▼ Long-distance radical cation transport was studied in DNA condensates where linearized pUC19 plasmid was ligated to an oligomer and transformed into DNA condensates with spermidine. DNA condensates were detected by Dynamic Light Scattering and observed by Transmission Electron Microscopy. Introduction of
charge into the condensates causes long-distance
charge migration, which is detected by reaction at the remote guanines. The efficiency of
charge migration in the condensate is significantly less than it is for the corresponding oligomer in solution. This result is attributed to a lower mobility for the migrating radical cation in the condensate, caused by inhibited formation of
charge-transfer-effective states. Radical cation transport was also studied in DNA condensates made from an oligomer sandwiched between two linearized plasmids by double ligation. Unlike the single ligated plasmid condensates, the efficiency of
charge migration in the double ligated plasmid-condensates is high, indicative of local structural and conformational transformation of the DNA duplexes.
Organic monomer units having extended ð-conjugation as part of a long conducting polymer was synthesized and characterized. The monomer units were covalently attached to particular positions in DNA oligonucleotides by either the convertible nucleotide approach or by phosphoramidite chemistry. Successful attachment of the monomer units to DNA were confirmed by mass spectral analysis. The DNA-conjoined monomer units can self assemble in the presence of complementary sequences which act as templates that can control polymer formation and structure. By this method the para-direction of the polymer formation can be enforced and may be used to generate materials having nonrecurring, irregular structures.

▼ The dynamical simulation of biophysical systems requires force fields (interaction potentials) capable of describing bond formation and breaking and reactive
charge transfer. Molecular motor proteins such as kinesin, dynein and myosin have the extraordinary ability of converting chemical energy to mechanical energy by the process of ATP hydrolysis used for motility. This work is motivated by the reactive force field developed recently by Valone and Atlas[1—4], the
charge-transfer embedded atom method (CT-EAM). CT-EAM is based on the empirical embedded-atom method (EAM) pioneered by Daw and Baskes[5]. CT-EAM extends the EAM to re- active molecular systems, through a formal basis in density functional theory. Here we report results on the development of a database for reparameterizing the earlier CT-EAM water potential developed by Muralidharan et al.[6], and for developing a new CT-EAM potential for the amino acids that are the building blocks of all proteins. The reparametization will involve using this extensive ab initio conformational fitting database for six amino acids: glycine, alanine, cysteine, serine, proline, and lysine. These amino acids were chosen to represent canonical subclasses (polar, charged, hydrophobic, ring) of the 20 naturally-occurring amino acids, thereby incorporating varying degrees of
charge transfer and solvent interactions. The conformers for each amino acid, identified using a stochastic search method adapted from the work of Saunders[7], further sample distinct structural and bonding patterns. The full database includes information on the energetics of transition states linking selected amino acid conformers, an extensive survey of local minima for each amino acid, dipole moments for each conformer and includes several hitherto uncharacterized structures including novel unsolvated zwitterionic-like structures. All electronic structure calculations were performed at a high level of theory (electron correlation and high quality basis set, MP2/6-311++G**), in order to distinguish correctly between nearly-isoenergetic conformers. The resulting CT-EAM potential fitted to this database will be assessed by comparison with ab initio results for solvated amino acids and dipeptides.

▼ This thesis focuses on two of the most active fields of chemical physics. One is long-range charge transfer in complex molecular systems such as DNA, and another is quantum dissipation that is about the general theory of complex molecular system. Part I is on charge transfer in DNA molecules. Starting with the introduction of the standard electron transfer theory, we overview and summarize the current research status of charge transfer in DNA in both theory and experiment in Chapter 1. To build a bridge between theoretical calculations and experimental chemical yields, Chapter 2 presents a formulation based on a superexchange-mediated sequential hopping model. An exact mapping between the stationary chemical yields and the normalized electric currents is established, followed naturally by the Ohm's law for the kinetic multistep hopping processes. To determine the coherent unistep (superexchange) contributions, the scattering matrix technique is exploited. In order to examine the possibility and effects of partially incoherent tunneling in DNA systems, a generalized scattering matrix formalism is constructed in Chapter 3. This is a generalized Büttiker phase-breaking formalism that clearly elucidates the interplay of electron resonance, coherence, dephasing, inelastic scattering, and heterogeneity effects, which are known to be physically important in long range electron transfer/transport processes. Obtained is an analytical expression of partially incoherent tunneling probability in model donor-bridge-acceptor systems with arbitrary lengths and sequences. To take the effects of electronic structure and its incoherent interaction with aqueous solution into account, Chapter 4 gives a quantum chemistry based Green’s function formulation, and thus elucidates the mechanism of long-range charge transfer in DNA double helix at a microscopic level. Semiquantitive comparisons with experiments are also obtained. Part II is about the development of quantum dissipation theory, together its application to a general topic of quantum stochastic resonance transport. After a general overview of the background knowledge in Chapter 5, a Liouville-space algebraic approach is exploited in Chapter 6 to revisit and further bridge between two most commonly used quantum dissipation theories, the Bloch-Redfield theory and Fokker-Planck equations. The nature of the common approximation scheme involving in these two theories is analyzed in detail. With the general theory built on a solid basis, the cooperative effects of driving and dissipation on transport in a model two-level system is then studied in Chapter 7. Analyzed in detail are the rate-matching and Rabi resonance conditions for the tunneling stochastic resonance. Large amplitude transport is found near not only the fundametal-harmonics region, but also higher harmonic resonance vicinities. Demonstrations are carried out to highlight the interplay between the strength of dissipation, and the intensity and frequency of external driving field. Finally, we make a brief summary of…

▼ In this thesis electrochemical and photoelectrochemical investigations on
n-molybdenum disulfide and p-tungsten diselenide are presented. They have good
preconditions to be used in thin film solar cells. So far the major drawback
are the surface states induced by unsaturated bonds at the crystal edges which
lower the efficiency of energy conversion. A major focus of this work was the
investigation of the semiconductor/electrolyte interface. For the measurements
mainly n-type MoS2 and some p-type WSe2 samples were used. As basic
characterisation the back contact was tested. With AFM and XPS the surface was
investigated. Hall and conductance measurements were performed for the
electronic parameters and cyclic voltammetry and DEMS were carried out to test
the electrochemical behaviour. The characteristics of these crystals under
illumination were investigated using the combinatoric technique of
simultaneous measurement of the photocurrent and the microwave reflection. By
this method it is possible to detect the excess
charge carriers that reach the
external circuit (photocurrent) and the ones that remain in the semiconductor
(microwave reflection). The measurement of the from the periodically
illuminated crystal reflected microwave radiation provides the light induced
change in photoconductance. This change in conductance is proportional to the
number of excess
charge carriers that remain in the semiconductor whereby
their behaviour can be studied under different experimental conditions. The
measurements were performed potential controlled in a three electrode setup
with different electrolytes and different excitation wavelengths. By the
variation of the electrolytes the border cases of inhibited and uninhibited
charge transfer were approximated. Thereby conclusions on the
charge transfer
could be drawn. The behaviour of
charge carriers in the bulk and in space
charge region could be explored separately analysing different penetration
depth of different wavelengths. To passivate the unsaturated bonds at the
crystal edges, the surface was treated with different molecules (cysteine,
EDTA and Tween 80) and the impact on corrosion,
charge transfer and
recombination investigated. Tween 80 showed an effective reduction of dark and
photo corrosion in electrochemical inert electrolyte, whereas the photocurrent
was enhanced in electrolyte with redox system. Similar results were obtained
by the treatment with EDTA but to a smaller extent. If the surface was treated
with cysteine the photocurrent was also enhanced in analogy to the results of
the other adsorbed compounds. In electrochemical inert electrolyte along with
the reduction of photo corrosion a quenching of excess
charge carriers in the
semiconductor was observed. Finally the sensitivity factor of the microwave
reflection was calculated measuring at 875 nm illumination wavelength. This
sensitivity factor could be used to calculate a
charge transfer constant for
holes under conditions of a moderate
charge transfer.

▼ Ce travail porte sur l'obtention et la caractérisation de composites polymères à charges organiques et inorganiques obtenus par polymérisation radicalaire in situ de monomères dans une matrice organique de type cellulose ou inorganique de type silicate. Avec la cellulose, les monomères retenus sont d'abord des dérivés vinyliques de type acide (méth)acrylique et de comonomères tels que l'anhydride maléique, le styrène et le chlorométhylstyrène. Les produits sont caractérisés notamment par ATG et XRD. La conductivité électrique de ces composites en fonction de leur gonflement a été étudiée. La copolymérisation de l'anhydride maléique avec le dicyclopentadiène est ensuite étudiée dans le toluène et le dioxane. Ce type de copolymère n'avait pas été étudié jusqu'à présent. L'influence du type de solvant sur la conduite de la réaction est étudiée. La caractérisation des composites est effectuée par IR, XRD et microscopie SEM. L'interaction entre les composants est mise en évidence par XRD. Les composites à base de silicate sont obtenus par polymérisation radicalaire contrôlée après greffage de l'amorceur sur le support inorganique. Le greffage est caractérisé par IR. Les analyses XRD et IR mettent en évidence la prédominance du greffage du polymère à la surface du silicate. L'étude de la copolymérisation chlorométhylstyrène - méthacrylate d'hydroxyéthyle a été effectuée qui montre in fine l'influence du support sur la structure des copolymères. De même, les analyses XRD et IR révèlent la modification de la structure du silicate. La microscopie SEM met en évidence des structures homogènes. Une étude complète de dégradation thermique a été menée par ATG qui montre l'influence des différents polymères
The synthesis of organic-polymer or inorganic-polymer composites was a real challenge within the last decades due to the difficulty of optimally dispersing the reinforcing agent into the polymeric matrix. A method to solve this problem is the "in situ "polymerization. The first part of the experimental study deals with the synthesis of the polymer-cellulose composites. Cellulose-containing composites based on copolymers of acrylic acid with styrene, 4-chloro-methyl-styrene and maleic anhydride or based on copolymers of methacrylic acid with styrene and 4-chloro-methyl-styrene were prepared for proton conducting membranes. Next, cellulose composites with maleic anhydride – dicyclopentadiene copolymer matrix were obtained by “in situ” free-radical polymerization. The syntheses were carried out in two different solvents: toluene and dioxane, aiming to determine their influence upon both the polymerization process and properties of the resulting materials. To the best of our knowledge, studies concerning the preparation of this composite have not been published in the literature until now. The second part of the original contributions section is dedicated to the investigation of some polymer-layered silicates composites, using a commercial layered silicate (Cloisite 30B), modified with OH-containing quaternary ammonium salts.…

▼ One electron oxidation of DNA has been studied extensively over the years. When a
charge is injected into a DNA duplex, it migrates through the DNA until it reaches a trap. Upon further reactions, damage occurs in this area and strand cleavage can occur. Many works have been performed to see what can affect this damage to DNA. Netropsin is a minor groove binder that can bind to tracts of four to five A:T base pairs. It has been used in the studies within to determine if it can protect DNA against oxidative damage, caused by one-electron oxidation, when it is bound within the minor groove of the DNA. By using a naphthacenedione derivative as a photosensitizer, several DNA duplexes containing netropsin binding sites as well as those without binding sites, were irradiated at 420 nm, analyzed, and visualized to determine its effect on oxidative damage. It has been determined netropsin creates a quenching sphere of an average of 5.8 * 108 Šwhether bound to the DNA or not. Herein we will show netropsin protects DNA against oxidative damage whether it is free in solutions or bound within the minor groove of a DNA duplex.

▼ Multi-step photoinduced electron transfer takes place over a large distance in the photosynthetic reaction centres (PRCs). Electron donor in this life-spending event is the photo-excited 'special pair', a unit of two electronically coupled porphyrinoid chromophores. Bacteriopheophytin and two quinone molecules function as electron acceptors and contribute to the charge separation with almost unit quantum efficiency.The natural photosynthetic reaction centre is the most sophisticated molecular electronic device to date and interest is high in increasing our understanding of the basic quantum mechanical principles behind efficient electron transfer and ultimately copying Nature and construct similar efficient devices.Two main approaches towards a better understanding of the mechanisms involved have been taken. The more biological disciplines isolate, cultivate and alternate reaction centres whereas synthetic chemists prefer to construct well-defined models that mimic certain aspects of the reaction centres. Such a synthetic approach is described in the 'Synthesis of Advanced 'Special Pair' Models for the Photosynthetic Reaction Centre'. The aspect to be mimicked is the 'special pair'. One or two porphyrins in a well-defined spatial disposition (kinked or non-kinked in respect to each other) were to act as electron donor in rigid bichromophoric and trichromophoric systems. A tetracyanonaphthoquinodimethane (TCNQ) unit was employed as the electron acceptor in the series of dyads synthesised. The TCNQ acceptor was replaced by a naphthoquinone (NQ) primary acceptor covalently linked to a TCNQ secondary electron acceptor in the series of triads. Rigid norbornylogous bridges held the chromophores in place and Diels-Alder methodology as well as condensation reactions were applied to link donor, bridge and acceptor components.Despite larger interchromophoric separation than in the natural 'special pair', the two porphyrin chromophores of the series of 'special pair' dyads show some interaction and thereby prove the success of our approach towards 'special pair' mimics. Strong fluorescence quenching in the porphyrin-TCNQ dyads indicates the sought after electron transfer process.A number of synthetic problems experienced and overcome in the synthesis of the series of triads led to discovery of a one-step 'bis-ketonisation' from an olefin under Sharpless bis-hydroxylation conditions with N-methylmorpholine-N-oxide. High pressure was applied to circumvent a lack of reactivity in the condensation reaction used to attach the porphyrin moieties (one or two) to the donor backbone. For the linkage of donor, bridge and acceptor component, a procedure was developed and successfully applied to give the giant mono-porphyrin-NQ-TCNQ trichromophore. In a similar manner 'special pair' trichromophoric systems should be available as part of future work.

▼ TEMPO-mediated oxidation is a widely used approach to introduce aldehyde and carboxyl groups on cellulose. In the conventional TEMPO-mediated oxidation, the mediator TEMPO is a small molecule. Previous research in our group advanced TEMPO-mediated oxidation by grafting TEMPO onto high molecular weight poly(acrylic acid) and polyvinylamine. The polymer grafted TEMPO-mediated oxidation required less TEMPO and had a lower environmental impact.
This thesis describes new insights into the role of polymer grafted TEMPO as mediator for cellulose oxidation. The redox-activity of grafted TEMPO was analyzed by electrochemical techniques and the resulting aldehyde densities on cellulose surfaces, produced by polymer grafted TEMPO, were determined with a fluorescence-labeling method.
The properties of polymer grafted TEMPO solutions are essential to understanding the role of grafted TEMPO as the oxidation mediator. TEMPO substitution compacted both the conformation of poly(acrylic acid) and polyvinylamine due to the lower hydrophilicity of the TEMPO substituents. Poly(acrylic acid-g-TEMPO) (PAA-T) solutions phase separated over the pH range 2-4, whereas at lower and higher pH the polymer was water-soluble. The phase separation at low pH was proposed to be the combined result of the hydrophobic contributions of the TEMPO moieties and electrostatic interactions between the acid-induced cationic TEMPO species and the anionic ionized carboxyl groups. Polyvinylamine-g-TEMPO (PVAm-T) was water-soluble over a larger pH range (pH 1-9) due to the ionization of the amine groups. Both the PAA-T and PVAm-T were slightly surface active.
Multilayer films composed of PVAm-T and poly(styrene sulfonate) were stable and redox-active.
Charge transport in the redox multilayer films was realized through TEMPO-to-TEMPO electron hopping between neighboring TEMPO moieties. Only 20-30% of TEMPO moieties were redox-active, reflecting the requirement that TEMPO moieties must be closer than ~ 0.6 nm for electron hopping to occur. The redox multilayer films displayed significant interpenetration of layers. The ability of PVAm-T to spontaneously adsorb onto negatively charged surfaces in aqueous solutions provides an easy route to TEMPO-rich surfaces for other applications.
Specific attention was focused on the role of PVAm-T as mediator for cellulose oxidation in the presence of laccase. Positively charged PVAm-T formed colloidal complexes with negatively charged laccase. The behaviors of PVAm-T/laccase mixtures displayed the classic features of polyelectrolyte complexes formed between oppositely charged polyelectrolytes. For the first time, electrochemical quartz crystal microbalance with dissipation (EQCM-D) measurements were used to characterize the redox properties of the adsorbed PVAm-T/laccase complexes. The role of PVAm-T as mediator for cellulose oxidation depended upon TEMPO-to-TEMPO electron transfer within PVAm-T/laccase colloidal complexes. The aldehyde density on oxidized cellulose surfaces scaled with the square root of surface molar…

▼ The automotive industry is undertaking major technological steps in an effort to reduce emissions and fight climate change. To reduce the reliability on fossil fuels a lot of research is invested into electric motors (EM) and their applications. One such application is plug-in hybrid electric vehicles (PHEV), in which internal combustion engines (ICE) and EM are used in combination, and take turns to propel the vehicle based on driving conditions. The main optimization problem of PHEV is to decide when to use which motor. If this optimization is done with respect to emissions, the entire electric charge should be used up before the end of the trip. But if the charge is used up too early, latter driving segments for which the optimal choice would have been to use the EM will have to be done using the ICE. To address this optimization problem, we studied the fuel consumption during different driving conditions. These driving conditions are characterized by hundreds of sensors which collect data about the state of the vehicle continuously when driving. From these data, we constructed 150 seconds segments, including e.g. vehicle speed, before new descriptive features were engineered for each segment, e.g. max vehicle speed. By using the characteristics of typical driving conditions specified by the Worldwide Harmonized Light Vehicles Test Cycle (WLTC), segments were labelled as a highway or city road segments. To reduce the dimensions without losing information, principle component analysis was conducted, and a Gaussian mixture model was used to uncover hidden structures in the data. Three machine learning regression models were trained and tested: a linear mixed model, a kernel ridge regression model with linear kernel function, and lastly a kernel ridge regression model with an RBF kernel function. By splitting the data into a training set and a test set the models were evaluated on data which they have not been trained on. The model performance and explanation rate obtained for each model, such as R2, Mean Absolute Error and Mean Squared Error, were compared to find the best model. The study shows that the fuel consumption can be modelled by the sensor data of a PHEV test fleet where 6 features contributes to an explanation ratio of 0.5, thus having highest impact on the fuel consumption. One needs to keep in mind the data were collected during the Covid-19 outbreak where travel patterns were not considered to be normal. No regression model can explain the real world better than what the underlying data does.
Fordonsindustrin vidtar stora tekniska steg för att minska utsläppen och bekämpa klimatförändringar. För att minska tillförlitligheten på fossila bränslen investeras en hel del forskning i elmotorer (EM) och deras tillämpningar. En sådan applikation är laddhybrider (PHEV), där förbränningsmotorer (ICE) och EM används i kombination, och turas om för att driva fordonet baserat på rådande körförhållanden.

▼ A series of anthraquinone-linked DNA oligonucleotides was prepared and the efficiency of long-distance radical cation migration was measured. In one set of oligonucleotides, two GG steps are separated by either a TATA or an ATAT bridge. In these two compounds, the efficiency of radical cation migration from GG to GG differs by more than an order of magnitude. Replacement of the thymines in the TATA or ATAT bridges with 3-methyl-2-pyridone (t, a thymine analog) results in the much more efficient radical cation migration across the bridge in both cases. This is attributed to a decrease in the oxidation potential of t to a value below that of A. In contrast, replacement of the thymines in the TATA or ATAT bridges with difluorotoluene (f, a thymine analog with high oxidation potential) does not measurably affect radical cation migration. These findings are readily accommodated by the phonon-assisted polaron-hopping mechanism for long-distance
charge transfer in duplex DNA and indicate that DNA in solution behaves as a polaronic semiconductor.
Oligomers containing thiophene-pyrrole-thiphene (SNS) monomers were covalently linked to the nucleobases of DNA. Treatment of these oligomers with horseradish peroxidase and hydrogen peroxide lead to the formation of conducting oligomers conjoined to the DNA. The DNA template aligns the oligomers along one strand of the duplex and limits the intermolecular reaction of monomers. This method enables utilization of the unique self-recognizing properties and programmability of DNA to create tailored oligomers.

▼ With the recent advances in micro-electronics and exponential rise in demand for electronic devices and their miniaturization, it is of utmost importance that self-diffusion phenomena in silicon be well understood. However, self-diffusion of silicon clusters with fraction vacancies is still not well understood as is evident from the fact that the reported values of activation enthalpy of self-diffusion via vacancies range from 3.6 to 4.9 eV, for various experiments carried out in the same temperature range of 650 degrees C to 1388 degrees C, which indicates how imprecise the existing measured values are for the same temperature range. This work overcomes the experimental limitation using molecular dynamics to calculate the self-diffusion coefficients both at room temperature and temperature above the melting point. Silicon clusters of the same spherical geometry and size with varying fraction vacancy have been studied using molecular dynamics and Tersoff potential to estimate phase changes and diffusion coefficients.
At 300 K, the self-diffusion coefficient values vary non-monotonically, i.e. at 7.5 % fraction vacancy the value of self-diffusion coefficient falls to half of its value at 0 % fraction vacancy while it increases by two orders of magnitude at 20 % fraction vacancy. At 2000 K, however, there is only a marginal monotonic increase with gradually varying fraction vacancy. It is found that as fraction vacancy increases, the diffusion coefficient value of lithium in silicon shows non-monotonic behavior for the same number of Li atoms in silicon nanosphere which is an important result in a sense that the behavior of the variation of dopant diffusion with respect to vacancies is directly found in this work. This work thus furthers the understanding on vacancy mediated self-diffusion which can lead to better diffusion control essential to device miniaturization. It also provides information on the dependence of the temperature, energy, pressure and phase changes of the silicon clusters with varying fraction vacancy which can be critical as a guideline for material design and selection for thermoelectric, optoelectronic devices and thermal transducers.
It was also found that
charge equilibration, applied to small nanocluster system, gave more precise value of the diffusion coefficient.

▼ This study was carried out at Bibita Forest (Gura Ferda), southwest Ethiopia to determine floristic composition, vegetation structure and to identify community types and to investigate the role of environmental factors in the distribution of the vegetation.
60 relevés, 20 m x 20 m at 25 m altitudinal drop along an altitudinal gradient were laid to collect the data on cover–abundance (for trees and shrubs), DBH, height, density, seedling and sapling count (for trees only). The data on herbaceous species were collected from five, 5 m x 5 m subplots laid at four corners each and one at the centre of the large relevé. Two soil samples were taken from each relevé at a depth of 0–10 cm (topsoil) and 30–50 cm (subsoil). The analysis for soil pH, % sand, % clay, % silt, and Electrical Conductivity (EC) were done.
A total of 196 plant specimens belonging to 74 families and 170 genera were identified. The five most dominant families were Rubiaceae and Asteraceae (13 species each), Euphorbiaceae and Acanthaceae (9 species each) and Fabaceae (8 species). Out of 196 species 13 were endemic to Ethiopia. Ipomoea involucrata Beauv. and ? Harungana madagascariensis Lam. ex Poir. belonging to the families Convolvulaceae and Clusiaceae respectively were found to be new records for Ethiopia. Six community types were identified at 0.65 to 0.75 dissimilarity levels and each community was named after dominant tree and/or shrub species.
The study on vertical stratification showed that Bibita Forest(Gura Ferda) has the upper storey (above 29 m), middle storey (15–29 m) and lower storey (below 15 m). The study on vegetation and population structure showed that the density of tree species was high at the lower class levels. Density of trees greater than 2 cm DBH (ca. 777/ha), for height greater than 6 m the tree density (ca. 673/ha), basal area (ca. 70/ha), frequency of all the tree species (716/ha) and the respective IVI values for each tree species were also calculated. The comparison of Bibita Forest (Gura Ferda) with other forests in Ethiopia with respect to tree densities, percentage distribution of tree species, basal area and phytogeographical comparison was done.
Soil environmental factors such as pH of the top and subsoils, clay and sand particles of both the top and subsoils showed significant relations with altitude, species richness and diversity.

Soil environmental factors such as pH of the top and subsoils, clay and sand particles of both the top and subsoils showed significant relations with altitude, species richness and diversity.

▼ Phosphorescent organic light emitting diodes are
making major impacts on consumer electronics and solid state
lighting. The emitting layer comprising a guest-host system plays
an important role in device efficiency and lifetime, the two
critical issues to which this thesis is devoted through exploration
of an emerging class of bipolar hybrid hosts. Major accomplishments
are recapitulated as follows. Two non-conjugated bipolar hybrid
compounds and their parent unipolar compounds were synthesized for
the characterization of their charge transport properties in
vacuum-sublimed films by the photocurrent time-of-flight technique.
It is demonstrated that charge-carrier mobility can be modulated
over three decades without affecting HOMO and LUMO levels or
triplet energies by varying the ratio of the electron-transport to
hole-transport moiety, and the molecular conformation dictated by
spacer length through computation. The ability to balance the
electron and hole fluxes through EML will be beneficial to
maximizing device efficiency and lifetime. Three representative
bipolar hybrids, tBu-TPA-p-TRZ, tBu-TPA-m-TRZ, and tBu-TPA-L-TRZ,
were synthesized and characterized for a comprehensive evaluation
of their potentials for PhOLEDs. External quantum efficiency is
diminished by the formation of charge transfer complexes (CTC) and
the deviation from charge balance through EML. The L-hybrid is the
least prone to CTC formation while suffering inferior charge
balance to afford an EQE intermediate between those of the m- and
p-hybrids. Nevertheless, the L-hybrid offers the most stable EML
against crystallization from the desired glassy film, thus holding
promise for the fabrication of superior PhOLEDs. A mixture of mCP
and SiPh4 and its chemical hybrid counterpart, mCP-LPhSiPh3, have
been employed to elucidate how thermal annealing of EMLs affects
the temporal stability of blue-emitting PhOLEDs. Annealing
mCP:SiPh4:FIrpic induced crystallization in 1 h, while
mCP-L-PhSiPh3:FIrpic consistently resisted crystallization under
all conditions. Without incurring pinhole formation in the absence
of a free surface presented by EML, annealing mCP:SiPh4:FIrpic at
60°C for 1 h led to about 50 % loss in EQE. In contrast,
the pristine device's EQE persisted with mCP-L-PhSiPh3:FIrpic
annealed at 60°C for up to 24 h. The concept of bipolar
hybrids holds promise for mitigating morphological instability as
one of the challenges to PhOLED lifetime.

▼ Thermal properties play important roles in
applications such as high efficiency thermoelectric materials and
the thermal management of electronic devices. While electrons
dominate thermal transport in metal, phonons
(i.e., the quanta of lattice vibrations) are the
primary energy carriers in crystalline insulators and
semiconductors such as Silicon and Germanium. A fundamental
understanding of the transport properties of multiple carriers
including phonons and electrons can enable us to better design
nanoscale materials. However, many of the current techniques to
calculate the lattice thermal conductivity and interfacial thermal
conductance involve major approximations. The
first part of this work involves studying the role of scattering
strength, such as anharmonicity (i.e., high
order phonon-phonon scattering) and electron-phonon coupling, on
thermal conductance at interfaces, based on Molecular Dynamics (MD)
simulations. The second part of this work involves building
accurate tools to predict the thermal conductivity of crystal
materials. One approach is MD simulations. The other approach is
lattice dynamics calculation from Boltzmann Transport Equations
(BTE) combined with Fermi’s golden rule, based on the force
constants fitted from first-principles calculations. It is so far
the most accurate approach and is essential for the prediction of
thermal conductivity in crystal materials. With
the completion of the tool for thermal conductivity prediction,
several important semiconductor materials are studied using these
first-principles methods. One is single layer molybdenum disulfide
(MoS
2), a two dimensional material with an
intrinsic bandgap of 1.8 eV and a high electron mobility around 200
cm
2V
-1S
-1,
which can potentially enable applications in transistors,
photovoltaics, valleytronics and thermoelectrics. Another material
studied is Wurtzite Zinc-Oxide (w-ZnO), a wide bandgap
semiconductor that holds promise in power electronics and
transparent electronics applications. Finally,
with the proven predictive power of our methods, we discover a
strategy to tune thermal conductivity via bond engineering by
modifying the bond saturation of materials. We find that
penta-graphene and hydrogenated penta-graphene are promising
candidates for future nanoelectronics applications due to their
high lattice thermal conductivity. This helps providing a general
guideline for the design of high thermal conductivity
materials. All these studies provide us a better
understanding of thermal transport in solid state crystal materials
and can potentially enable us to design materials with desirable
thermal transport properties.

▼ The aim of this study was to model the differentiation of paraxial mesoderm in
the mouse embryo using an in vitro system. A protocol was established that
allowed the generation of paraxial mesoderm from murine embryonic stem cells
with high efficiency. Using this in vitro differentiation technique,
transcriptional changes in murine embryonic stem cells were monitored and
analyzed in the course of their differentiation. To track the differentiation,
a dual reporter cell line was generated, harboring distinguishable fluorescent
reporter genes for T (Brachyury) and Msgn1 activity. These reporter genes
showed the transition to the primitive streak stage and adoption of mesoderm
fate, respectively. The differentiation of the reporter cells was induced in
serum-free medium containing two combinations of recombinant proteins, either
WNT3a and Noggin or BMP4 and DKK1. Using the two reporter genes, it was
possible to isolate cells of each stage of differentiation and do comparative
transcriptional analysis. It was found that both reporters were activated
under both conditions. Transcriptional analysis revealed that only after
stimulation with WNT3a and Noggin the cells showed expressional
characteristics of paraxial mesoderm and anterior streak derivatives. Genes
which were only upregulated in the Msgn1-reporter expressing population after
stimulation with WNT3a and Noggin were identified and represent genes with a
potential role in the development of paraxial mesoderm.

▼ Improved modeling of angled-dielectric insulation in high-voltagesystems is described for use in particle-in-cell (PIC) simulations.Treatment of non-orthogonal boundaries is a significant challenge inmodeling angled-dielectric flashover, and conditions on boundaries aredeveloped to maintain uniform truncation error in discretized spaceacross the dielectric angles studied. Extensive effort was expended inisolating particular operating regimes to illustrate fundamentalphenomenological surface effects that drive the discharges studiedherein; consequently, this document focuses on the phenomenology oftwo specific dielectric angles at 6.12° for multiplicative breakdown(the so-called single-surface multipactor) and 22.9° for anon-multiplicative discharge that evolves into a dark current atsteady state.Phenomenological results for simulations in vacuum through "ultra-lowpressures" on the order of a few hundred mTorr are presented. Amultipactor front forms via net emission of electrons from impact onthe dielectric surface, where emission leads to saturated fieldconditions in the wake of the front, producing a well-definedforward-peaked wave. A treatment of the gain and saturationcharacteristics is presented, isolating the surface electric fields asthe driving contributor to both metrics. Physical models includeoftenneglected effects such as space-charge, dielectric-surfacecharging, and particle distributions in energy and space. For thedischarges treated in this study, breakdown voltages of the typicalPaschen form are not applicable, since multiplicative conditions aredriven primarily by surface effects.Phenomenological results are also presented for simulations at lowpressure (~ 1Torr), which is shown to be a transitional limit wherevolume effects become appreciable compared to surface effects. Acoupling between space charge and surface charge is shown to lead tooscillatory effects in otherwise DC discharges. Surface multipactorleads to increased ionization and space charge, and the ensuingspace-charge momentum alters what would have been a steady-statesaturation as in the case of vacuum-like discharges. Models fordiffusive outgassed species are developed and implemented, extendingthe capabilities of the PIC suite.The overarching theme of this study is to communicate the dependenceof multiplicative discharges dominated by surface effects onnear-surface electric field conditions. It is shown through variousexamples from vacuum through low pressures, and in diffusive gases,that single-surface multipactor conditions can be expressed solely interms of the dielectric surface field angles. This treatment lays thefoundation for a novel extension of RF breakdown susceptibility theory[1] to the DC regime, grounding breakdown susceptibility to thewell-established fundamentals on secondary emission [2, 3]. Thistheory shows that breakdown characteristics can be modeled in ana-priori framework, hence the lack of a Paschen-type curve.Finally, the effect of the seed source on discharge characteristics isalso studied. A comparison between…

▼ Os dispositivos MEMS têm apresentado ao longo dos anos um elevado crescimento, contudo
as estruturas RF MEMS apresentam um problema, a sua fiabilidade. Esta deve-se ao facto de o tempo
de vida das estruturas estar limitado, entre outros, aos efeitos de carga. Este efeito deve-se à contínua
aplicação de um determinado valor de tensão sobre o atuador que, por sua vez, vai levar à injeção de
carga no dielétrico do atuador, devido aos elevados campos elétricos gerados sobre o mesmo. Ao fim
de algum tempo, esta acumulação de cargas vai começar a ser significativa, chegando a influenciar o
comportamento do atuador, bem como o seu tempo de vida.
Este efeito, devido à sua importância nos MEMS, tem vindo a ser foco de imensos estudos [1]–
[7]. Desde o impacto que o valor da tensão de atuação tem sobre o tempo de vida dos atuadores [1], a
sua caracterização e modelização [4] até novas abordagens, recorrendo a atuações bipolares [7], para
tentar eliminar este efeito. Por outro lado, tem também sido explorado o impacto que fatores como a
temperatura, o packaging ou mesmo a humidade provocam na carga acumulada no dielétrico.
Contudo, os efeitos de carga em estruturas MEMS de placas paralelas continuam ainda por explorar,
tendo apenas em [3] sido medida experimentalmente a variação no valor da tensão de pull-in que a
acumulação de cargas no dielétrico provoca. No entanto, são ainda inexistentes os modelos que
permitam relacionar os valores de densidade de carga com os valores de tensão aplicados, ou com a
variação da tensão de pull-in. Além disto, é também ainda desconhecido o impacto que os tempos de
atuação on/off apresentam no processo de carga do dielétrico.
Assim, nesta dissertação foi efetuado um estudo em estruturas MEMS de placas paralelas
visando a modelização das mesmas, onde um dos elétrodos do atuador é móvel e o outro se encontra
fixo. Estes atuadores, devido ao seu processo de fabrico DRIE, possuem em cada um dos seus
elétrodos uma fina camada de Teflon. Os modelos matemáticos considerados de base eram
provenientes do estudo realizado em [4]. Contudo, para o estudo levado a cabo nesta dissertação, foi
usado um tipo diferente de estrutura, apresentando uma tensão de atuação, enquanto a on, em rampa
até ser atingida a tensão de pull-in, ao contrário do modelo apresentado por [4], onde as atuações são
feitas com apenas um degrau de tensão. É também elaborado o estudo com o objetivo de observar o
impacto que os diferentes tempos de atuação têm no processo de carga do dielétrico.
Para os atuadores de placas paralelas foi observada uma relação linear entre a carga injetada
no dielétrico e o valor da tensão de atuação. Foi também observado que a densidade de carga injetada no dielétrico é dada diretamente pela razão da área do dielétrico. Quanto aos tempos de atuação, foi
observado que, com o aumento do tempo a off, o dielétrico demorava mais até carregar
completamente, podendo mesmo chegar a nunca carregar na sua totalidade, dependendo do tempo a
off.

▼ We are living in the era of Big Data, witnessing an exponential increase in the amount of generated data, primarily driven by the substantial increase in the use of connected devices and embedded sensors. Machine learning plays a critical role in extracting meaningful information from such collected data. Furthermore, there are growing application domains in which resource-constrained hardware platforms are required to run machine-learning applications locally. These resource constraints usually appear in the form of energy, power consumption, throughput, latency and area, making it necessary to create new design strategies. Since the end of the Moore's law era, hardware acceleration and parallelization have been established as key approaches for addressing the energy and performance of computational kernels. Although accelerators provide an opportunity to address resource constraints, they primarily improve computational operations and not the memory-accessing/data-movement operations. However, in data-centric workloads, data movement becomes the bottleneck. Thus the leverage of hardware acceleration and the range of kernels for which it is beneficial is limited.
In this dissertation, the main focus has been on three matters. First, on a technological level and for sparse linear algebraic computation kernels, the leverage that 3D IC technology offers is analyzed to enable increasing performance gains from hardware acceleration. This is demonstrated via introducing a three layer architecture consisting of the "DRAM layer", the "SRAM layer", and the "Computation layer", interfaced with vertical 3D interconnects between the adjacent layers. This architecture implements the sparse matrix-vector multiplication (SpMV) kernel, as an example of a kernel that suffers from irregularities in memory-accessing pattern. We identify the key architectural parameters of this accelerator and analyze their impact and inter-dependencies towards the overall throughput of the computations. We show that memory-bandwidth improvement along with the ability to provide data to parallelized (and thus spatially-distributed) computational units are the key aspects which enable SpMV to benefit from acceleration.
Secondly, for dense linear algebraic computation kernels, we demonstrate the first
charge-domain in-memory-computing accelerator that integrates dense weight storage and multiplication in order to reduce the overall data movement. This is achieved via incorporating the computations inside the very compact memory bit cells, and using highly linear and stable interdigitated Metal-Oxide-Metal (MOM) capacitors that are laid out on top of the bit cells, occupying no additional area. The system demonstrates high computational accuracy primarily as a consequence of the very good matching, process, and temperature stability of the MOM capacitors (also shown to improve in advanced VLSI technology due to the more accurate lithographic precision). The silicon-CMOS prototype is fabricated in a 65nm CMOS and tested on several…

▼ Abstract: Infrared intensities of carbonyl stretching bands were studied using
charge-charge flux-dipole flux (QTAIM/CCFDF),
charge-charge transfer-counterpolarization (QTAIM/CCTCP) and atomic partition models, all of them developed by our group. Fourteen monocarbonyl and three dicarbonyl molecules were analyzed at MP2/6¿311++G(3d,3p) and QCISD/cc¿pVTZ levels of theory. The computational protocol stablished a decade ago was upgraded and now employs Gaussian09, AIMAll and the new release of Placzek programs. Good agreements were found between calculated and experimental molecular geometries, dipole moments, infrared frequencies and intensities of the carbonyl stretching band, in both levels of theory. The results, mainly from the CCTCP model, indicate a major importance of the
charge term, C², to the correct description of the total carbonyl stretching intensity, in agreement with the high polarity of the C=O bond in all molecules. This is particularly dramatic when the carbonyl is surrounded by highly electronegative groups like fluorine and hydroxyl. Furthermore, the smaller
charge separation in the less polar organic molecules lead to weaker total intensities, but the dominance of the
charge term is verified for these molecules as well. Differences in intensities of two given molecules can be explained by simple models concerning the similarity of the neighboring groups; for example, substituting a hydrogen by a methyl group has a negligible effect in the intensities, but substituting a hydrogen or methyl by a fluorine or hydroxyl dramatically increases the total intensity, as well the CCFDF and CCTCP contributions. Nonetheless, the proportions between the different contributions are quite constant. The same is verified for the atomic contributions to the intensities, which are almost completely distributed between the carbon and oxygen atoms that compose the carbonyl group. Even though the atomic contributions of carbon and oxygen vary quite a lot with substituent change, their proportions to the total intensity always approach ? and ?, respectively. The proportions among the contributions are quite constant for the three different partition models (CCFDF, CCTCP and atomic), suggesting that they are characteristic patterns of the intensities of the carbonyl group, in a clear parallel with frequencies. Since this is a feature that was also verified for other chemical groups like C-X (X=F, Cl), O-H and C-H in hydrocarbons, one can look the proportions between the contributions as a fingerprint of the intensities in the IR spectra, even though they are not as readily visualized as the patterns in the frequencies. These patterns can be used to pin point vibrations in the IR spectra since they are characteristic of the group since they are as intrinsic of a given vibration as its vibrational frequency

▼ Ce projet de thèse, dans le cadre d’une collaboration entre le LIMOS et le LPC, s’inscrit dans une démarche de recherche permettant la mise en synergie des domaines de la biologie, de la physique et de l’informatique par la proposition d’une démarche de simulation permettant la réalisation d’expériences in silico. Pour cela, nous nous proposons de développer une plateforme logicielle dédiée à la modélisation multiéchelle des systèmes biologiques qui pourra par la suite être interfacée avec les outils de simulation de physique des particules. Nous proposons également un modèle individu-centré de cellule biologique paramétrable à l’aide de données obtenues d’expériences in vitro. Nous présentons l’élaboration de cette plateforme et une démarche de validation de ses fonctionnalités à travers l’implémentation de modèles d’automates cellulaires de la littérature. Nous présentons ensuite la construction du modèle de cellule biologique en prenant le temps d’expliquer comment est pris en compte le système biologique, comment nous le modélisons puis comment nous paramétrons le modèle. Nous modélisons les processus internes de la cellule, dont les caractéristiques sont liées à l’information génétique qu’elle porte. Ce modèle de cellule permet de reproduire le comportement d’une cellule isolée, et à partir de là, d’un ensemble de cellules via l'automate. Le modèle est ensuite utilisé pour retrouver les courbes de croissance d'une population de bactéries Escherichia coli. Des valeurs de données de fluxomique ont été exploitées et ont permis la reproduction in silico des expériences in vitro dont elles étaient issues.
This PhD thesis project is part of a research program in the fields of biology, physics and computer science aiming to propose a simulation approach for performing experiments in silico. For this, we propose to develop a software platform dedicated to multi-scale modeling of biological systems that can be combined with particle physics simulation tools. We also propose a general individual-based model of biological cell in which data obtained from in vitro experiments can be used. We present the development of this platform and the validation process of its functionalities through the implementation of cellular automata from the literature. We then present the design of the biological cell model by giving the hypothesis we made, how we model and how we parameterize the model. Starting from a simple biological system, bacteria, observed in liquid culture, our model uses a multi-scale middle-out approach. We focus on the cell and we model internal processes, assuming that all their properties come from genetic information carried out by the cell’s genome. This model allows to consider the cell behavior, and then to obtain the behavior of a cell population. Data from fluxomic experiments have been used in this model to parameterize the biochemical processes. The results we obtain allow us to consider the model as validated as simulation results match the experimental data.

▼ Le cancer broncho-pulmonaire (CBP) le 4ème cancer le plus répandu au niveau mondial après les cancers de la prostate, du sein et du côlon. Diagnostiqués à des stades tardifs, il est la première cause de cancer par décès. Cependant, une meilleure compréhension des mécanismes moléculaires sous-jacents au cancer a permis de développer des thérapies personnalisées pour chaque patient. L’émergence des thérapies ciblées et de l’immunothérapie a révolutionné la prise en
charge thérapeutique, permettant d’améliorer la survie globale, la survie sans progression et les effets secondaires des patients en comparaison avec les traitements de chimiothérapies conventionnelles. La prescription des thérapies personnalisées est basée sur les caractéristiques moléculaires de la tumeur et, par conséquent, nécessite des analyses moléculaires innovantes. Néanmoins, entre 10 et 30% des analyses moléculaires des patients atteints de CBNPC sont non contributives et l’accès aux thérapies ciblées est compromis. De plus, même si l’analyse anatomo-pathologique reste utile pour l’évaluation du stade ou encore de l’histologie, elle reste peu adaptée en cas d’actes répétitifs, tout au long de la maladie. La « biopsie liquide », est un concept émergeant, correspondant à l’analyse des acides nucléiques circulants mais aussi des cellules tumorales circulantes (CTC), issus de la tumeur. Cette méthode faiblement invasive, basée sur un prélèvement sanguin, permet d’analyser le patrimoine tumoral circulant et donne accès aux informations moléculaires de la tumeur primaire. Le développement de nouvelles activités de diagnostic est donc primordial pour répondre à ses nouvelles demandes cliniques. Depuis 2015, les Hospices Civils de Lyon (HCL) ont déployé un programme de recherche translationnelle, appelé CIRCAN « CIRculating Cancer » dans lequel s’inscrit ce travail de thèse. De nombreuses méthodes de détection des biomarqueurs pertinents en oncologie thoracique dans l’ADNcir ont été développées et été validées au laboratoire pour plus de 1500 patients actuellement, leur permettant de bénéficier de thérapies ciblées. L’optimisation et la validation des technologies de biologie moléculaire telles que le séquençage à haut débit et la PCR digitale ultra-sensible ont été réalisées durant ce travail de thèse et valorisées dans des journaux internationaux. Au-delà des thérapies ciblées, les immunothérapies représentent les nouveaux traitements prometteurs pour ces patients dont le taux d’expression PD-L1 sur biopsie tissulaire est le biomarqueur de choix. Etant donné les contraintes qu’occasionne la biopsie tissulaire, nous avons développé un protocole de caractérisation phénotypique de PD-L1 dans les CTC. De plus, de nombreuses études montrent la pertinence clinique de l’utilisation de la
charge mutationnelle (TMB) comme marqueur prédictif de réponse à l’immunothérapie. En parallèle, nous avons développé des outils moléculaires en cours de validation pour le calcul du TMB dans l’ADNcir et dans les CTC en comparaison avec celui calculé dans le tissu, et le taux…

▼ Les cellules T jouent différents rôles dans la réponse immunitaire adaptative : elles stimulent les cellules B à produire les anticorps ; elles sécrètent les cytokines qui dirigent l'action des autres cellules immunitaires ; elles tuent les cellules du corps infectées ou porteuses de mutations ; elles assurent la mémoire immunitaire, permettant de répondre plus vite en cas de nouvelle infection avec le même pathogène. Toutes les cellules T s'activent quand elles reconnaissent leur antigène spécifique : un peptide court présenté par le complexe majeur d'histocompatibilité exprimé à la surface de la cellule présentatrice d'antigène. La liaison du récepteur de cellules T (TCR, ang. T cell receptor) à cet antigène initie la cascade de transduction de signal dans la cellule T ; ce processus mène aux modifications du cytosquelette, aux changements dans l'expression des gènes, et à la prolifération des cellules T. Récemment, il a été découvert que quand les cellules T reconnaissent l'antigène, elles poussent et tirent sur les cellules présentatrices d'antigène. Même si ces forces mécaniques ont été l'objet de recherches intenses pendant ces dernières années, leur nature et leur rôle restent toujours largement méconnus. La caractérisation des forces générées par les cellules T était l'objectif de ma recherche doctorale. J'ai mesuré les forces avec la technique appelée "micropipette force probe", qui utilise une micropipette en verre comme un cantilever de rigidité connue. Cette technique a permis de mesurer la force maximale et la vitesse de génération des forces, et, en même temps, de capturer l'image de la morphologie des cellules de profil. J'ai trouvé que les cellules T humaines, primaires, au repos, CD4+, activées avec les anticorps contre les molécules CD3 et CD28, suivent une succession de changements de morphologie, pendant laquelle elles génèrent des forces. Cette succession était qualitativement identique pour les lymphoblastes CD4+, un modèle des cellules T activées. Ensuite, j'ai étudié cette succession d'événements dans le contexte biologique de l'activation des cellules T. Les cellules T interagissent avec les cellules présentatrices d'antigène qui ont des propriétés mécaniques différentes. J'ai donc changé la rigidité de la micropipette utilisée comme sonde, afin de mesurer la réponse des cellules T à des cibles de rigidité différentes. J'ai trouvé que les forces générées par les cellules T sont mécanosensibles, car la vitesse de génération des forces de poussée et de traction changeaient avec la rigidité de la micropipette. Ensuite, j'ai étudié les conditions nécessaires à la génération des forces. Les forces étaient liées au processus d'activation, car l'attachement des anticorps aux molécules CD45 n'a pas conduit à la génération des forces. Pour étudier la contribution aux forces des différents acteurs du cytosquelette d'actine, j'ai utilisé différents inhibiteurs du remaniement du cytosquelette. L'influence la plus grande sur la génération de forces a été trouvée avec SMIFH2, un inhibiteur des formines.…

▼ As doenças cerebrovasculares de aparecimento súbito e as doenças osteoarticulares são
condições que conduzem à perda funcional, com limitação da mobilidade e consequente
dependência nos autocuidados.
Este relatório pretende expor a efetivação de um projeto de intervenção profissional
baseado num programa de cuidados de enfermagem de reabilitação, a pessoas com alteração
da mobilidade causada por AVC ou por artroplastia total da anca, avaliando os efeitos das
intervenções que visam a capacitação para a autonomia no autocuidado transferir-se.
Após a implementação do programa observou-se uma melhoria significativa na força
muscular, na propriocepção e no equilíbrio, contribuindo assim para a melhoria da
mobilidade e conduzindo à autonomia no autocuidado transferir-se.
Conclui-se que o programa de cuidados de enfermagem de reabilitação implementado,
teve resultados positivos melhorando a funcionalidade e o grau de autonomia no autocuidado
transferir-se; Abstract:
“Capacitation of the person with change of mobility, for autonomy in the self-care of
transfer”
The cerebrovascular diseases of sudden onset and the osteoarticular diseases are
conditions that lead to functional loss, with limited mobility and consequent dependence on
self-care.
This report intends to expose the implementation of the project of professional
intervention of rehabilitation nursing to people with stroke and people undergoing total hip
arthroplasty, who find themselves with mobility disorders, evaluating the effects of a
rehabilitation nursing program that aims to empower autonomy in the self-care of transfer.
After the implementation of the program, a significant improvement in muscle strength
and balance was observed, by the Lower Scale, Morse Falls Scale and Tinetti Index, thus
contributing to the improvement of the functionality assessed by the Functional
Independence Measure and leading to autonomy in self-care of transfer.
It is concluded that the rehabilitation nursing care implemented has positive results,
improving functionality and functional independence level in people with impaired mobility.

▼ Les transferts horizontaux (TH) d’ADN sont de plus en plus reconnus comme un phénomène important dans l’évolution des métazoaires. La grande majorité des TH entre animaux implique des éléments transposables (ET), séquences génomiques égoïstes capables de se déplacer par transposition dans le génome et générer ainsi de multiples copies. Si ces TH d’ET semblent avoir un rôle prépondérant dans l’évolution des métazoaires, les mécanismes sous-tendant ces TH restent mal connus. Un des mécanismes possibles implique les virus qui pourraient être des vecteurs d’ADN entre les hôtes qu’ils infectent. Cette thèse contribue à évaluer cette hypothèse.Dans le premier Chapitre, nous avons étudié l’impact du stress provoqué par une infection virale sur l’activité des ET. Certains ET sont surexprimés au cours de l’infection, et certains sont aussi exprimés après leur insertion dans des génomes viraux.Dans le deuxième Chapitre, nous avons élargi le spectre des systèmes hôte-virus connus à ce jour dont les ET de l’hôte transposent dans les génomes viraux. L’analyse de 11 de ces systèmes a permis de découvrir neuf nouveaux systèmes dont des ET hôtes sont retrouvés dans les génomes du virus. Cette étude nous a permis d'inférer la capacité des ET portés par les génomes viraux à transposer vers d'autres génomes viraux, ce qui constitue un des résultats majeurs de cette thèse.Dans le troisième Chapitre, la construction d'un pipeline bioinformatique a permis de caractériser de nombreuses insertions complètes d’ET dans les génomes viraux, ainsi que la diversité des variants structuraux génomiques présents dans quatre populations de grands virus à ADN double-brin.Dans le dernier Chapitre, l’intégration d’un génome complet de rétrovirus murin dans le génome d’une lignée cellulaire humaine a été caractérisée, fournissant des résultats supplémentaires sur les TH de virus dans l’hôte.Dans l’ensemble ces travaux apportent un éclairage nouveau sur le rôle des virus dans les TH d’ADN chez les métazoaires.
Horizontal transfers (HTs) of DNA are increasingly recognized as an important phenomenon in the evolution of metazoans. The vast majority of HTs between animals involves transposable elements (TEs), selfish genomic sequences capable of moving by transposition in the genome and thus generating multiple copies. While these HTs of TEs seem to have a major role in the evolution of metazoans, the mechanisms underlying these HTs remain poorly understood. One possible mechanism involves viruses which could be vectors of DNA between the hosts they infect. This thesis helps to evaluate this hypothesis.In the first chapter, we studied the impact of stress caused by a viral infection on the activity of TEs. Some TEs are overexpressed during infection, and some are also expressed after their insertion into viral genomes.In the second chapter, we have broadened the spectrum of host-virus systems known to date, in which host TEs transpose into viral genomes. Analysis of 11 of these systems revealed nine new systems in which host TEs were found in the genomes…

▼ Deux systèmes biologiques distincts, les muscles squelettiques et les sites d'adhésion de cellules kératocytes en mouvement, sont considérés dans un même cadre en raison de la similitude profonde de leur structure et de leur fonctionnalité. La réponse passive de l'un et de l'autre peut être modélisée à l'aide d'un grand nombre d'unités multi-stables couplées par des interactions à longue portée, et exposées à un désordre spatial fixé et un bruit thermique/mécanique. Les interactions à longue portée dans de tels systèmes conduisent à une synchronisation malgré les fluctuations temporelles et spatiales. Bien que les deux systèmes biologiques considérés présentent des différences structurelles importantes, nous montrons que l'on peut identifier une structure de verre de spin sous-jacente commune. À la lumière de cette analogie, ces systèmes vivants semblent être proches de points critiques et, à cet égard, le désordre gelé, reflétant l’incommensurabilité stérique des unités parallèles, peut être fonctionnel. Un autre paramètre important fixant la réponse est la rigidité interne du système qui couple les unités entre elles.
Two biological systems, a half-sarcomere of a skeletal muscle and an adhesive cluster of a crawling keratocyte, are considered in parallel because of the deep similarity in their structure and functionality. Their passive response can be modeled by a large number of multi-stable units coupled through long-range interactions, frustrated by quenched disorder and exposed to thermal noise. In such systems, long-range interactions lead to synchronization, defying temporal and spatial fluctuations. We use a mean-field description to obtain analytic results and elucidate the remarkable ensemble-dependence of the mechanical behavior of such systems in the thermodynamic limit. Despite important structural differences between muscle cross-bridges and adhesive binders, one can identify a common underlying spin glass structure, which we fully exploit in this work. Our study suggests that the muscle machinery is fine-tuned to operate near criticality, and we argue that in this respect the quenched disorder, reflecting here steric incommensuration, may be functional. We use the analogy between cell detachment and thermal fracture of disordered solids to study the statistics of fluctuations during cellular adhesion. We relate the obtained results to recent observations of intermittent behavior involved in cell debonding, also suggesting near-criticality. In addition to the study of the equilibrium properties of adhesive clusters, we also present the first results on their kinetic behavior in the presence of time-dependent loading.

▼ The ATLAS detector is a multi-purpose detector within the large hadron collider at CERN in Geneva. Its inner-most sub detector is the pixel detector which is an important part of the tracker system. It is a hybrid detector where readout electronics and sensors are manufactured separately and connected subsequently through bump bonds. Due to the location next to the interaction point sensors have to withstand high radiation. Test sensors were irradiated with neutrons at the JSI in Ljubljana and with protons at the irradiation center Karlsruhe and at CERN-PS. The radiation hardness of planar silicon n-in-n sensors was demonstrated in this thesis up to a fluence of 2E16 n_eq/cm², which is the expected end of life fluence for the inner layer after the HL-LHC upgrade of ATLAS. More
charge than calculated with a simple trapping model is collected, indicating that some sort of stable
charge amplification is taking place. The measurements were done with a
beta particle source and with high energy beams of electrons and pions at test beam sites. An excellent hit efficiency of 97% was achieved.
