▼ Complex networks are dynamic, evolving structures that can host a great number of dynamical processes. In this thesis, we address current challenges regarding the dynamics of and dynamical processes on complex networks. First, we study complex network dynamics from the standpoint of network growth. As a quantitative measure of the complexity and information content of networks generated by growing network models, we define and evaluate their entropy rate. We propose stochastic growth models inspired by the duplication-divergence mechanism to generate epistatic interaction networks and find that they exhibit the property of monochromaticity as a result of their dynamical evolution. Second, we explore the dynamics of quantum mechanical processes on complex networks. We investigate the Bose-Hubbard model on annealed and quenched scale-free networks as well as Apollonian networks and show that their phase diagram changes significantly in the presence of complex topologies, depending on the second degree of the degree distribution and the maximal eigenvalue of the adjacency matrix. We then study the Jaynes-Cummings-Hubbard model on various complex topologies and demonstrate the importance of the maximal eigenvalue of the hopping matrix in determining the phase diagram of the model. Third, we investigate dynamical processes on interacting and multiplex networks. We study opinion dynamics in a simulated setting of two antagonistically interacting networks and recover the importance of connectivity and committed agents. We propose a multiplex centrality measure that takes into account the connectivity patterns within and across different layers and find that the dynamics of biased random walks on multiplex networks gives rise to a centrality ranking that is different from univariate centrality measures. Finally, we study the statistical mechanics of multilayered spatial networks and demonstrate the emergence of significant link overlap and improved navigability in multiplex and interacting spatial networks.

▼ This work aims to inform the formulation and processing of polymer mixtures through the use of models that have minimally sufficient complexity. Models with minimal complexity are easier to develop, understand, explain, and extend, all of which underpin model validation, verification, and reproducibility. We develop simplified models for two different material systems, semiconducting polymers and thermosets. With the relatively low cost of predicting morphologies enabled by these models, we investigate structure-property-processing relationships in record system sizes and combinatorial parameter spaces. The insight from these models lays the foundation for improving the efficiency of organic solar cells and air travel. The morphology of the active layer of an organic solar cell determines its efficiency, but is also the most difficult aspect to control during manufacturing. Morphology can in principle be controlled through the thermodynamic self-assembly of active layer components. We develop models of two semiconducting polymers. We find our predictions are validated by morphological and charge transport measurements from experiments and we provide guidance for optimizing conditions for self-assembly. Thermoset polymers present a unique modeling challenge because their properties are sensitive to processing kinetics that are at odds with thermodynamic modeling frameworks. The primary source of this difficulty is bridging time (1×10−12s) and length scales (1×10−10m) of reaction dynamics with the time (1×102s) and length scales (1×10−6m) of morphology evolution. We implement a coarse-grained model of toughened thermosets where each amine, epoxy, and toughener mer is treated as a single simulation element. This simplification allows us to reach the time and length scales necessary to model the epoxy amine reaction and observe curing-driven morphology evolution. We simulate curing of (100 nm)3, million-particle volumes, which allows observation of experimentally-relevant volume evolution. To practice behaviors necessary for computational research to be usable and reproduced by others, we make available all the models, initial configurations, submission scripts, analysis scripts, and simulation data associated with this work with an opensource, permissive license. We describe software development practices and design choices that make this possible and discuss opportunities for improvement in future computational materials research.

▼ This thesis consists of two projects on the behaviour of a novel vibrating-wire rheometer and a third project studying the gelation dynamics of aqueous solutions of Pluronic F127. In the first study, we use COMSOL to perform two-dimensional simulations of the oscillations of a wire in Newtonian and shear-thinning fluids. Our results show that the resonant behaviour of the wire agrees well with the theory of a wire vibrating in Newtonian fluids. In shear-thinning fluids, we find resonant behaviour similar to that in Newtonian fluids. In addition, we find that the shear-rate and viscosity in the fluid vary significantly in both space and time. We find that the resonant behaviour of the wire can be well described by the theory of a wire vibrating in a Newtonian fluid if the viscosity in the theory is set equal to the viscosity averaged over the circumference of the wire and over one period of the wire’s oscillation at the resonant frequency. In the second study, we present the design and operation of our vibrating-wire rheometer and use it to measure the properties of Newtonian and viscoelastic fluids. We find that our device can accurately measure small viscosities. In homogeneous polymer solutions, we find that the viscoelastic moduli measured using our device are consistent with measurements at lower frequencies using a shear rheometer. In addition, we find that our device can measure the microrheological properties of an aging Laponite clay suspension that is heterogeneous on the micron scale. In the third project, we study the gelation dynamics of aqueous solutions of Pluronic F127. Using shear rheometry we find that when slowly heating the solutions, they undergo a transition from sol to gel around room temperature, followed by a gel to sol transition at a higher temperature. Our results show that these transitions take place over a temperature range of a few degrees. When cooling the solutions, the reverse transitions occur over a larger range of temperature and the width in temperature of the gel phase is larger. At temperatures near the phase transitions, we find that the rheological relaxation time becomes very long.

▼ The adhesion at solid/liquid interface plays a fundamental role in diverse fields and helps explain the structure and physical properties of interfaces, at the atomic scale, for example in catalysis, crystal growth, lubrication, electrochemistry, colloidal system, and in many biological reactions. Unraveling the atomic structure at the solid/liquid interface is, therefore, one of the major challenges facing the surface science today to understand the physical processes in the phenomena such as surface coating, self-cleaning, and oil recovery applications. In this thesis, a variety of theory/computational methods in statistical physics and statistical mechanics are used to improve understanding of water adhesion at solid/liquid interfaces. In here, we addressed two separated, but interconnected problems: First, we consider water adhesion on fiber/surface, responsible for the emergence of droplet residue upon droplet detachment. In this project, we study the mechanism of water droplet detachment and retention of residual water on smooth hydrophilic fibers and surfaces using nonequilibrium molecular dynamics simulations. We investigate how the applied force affects the breakup of a droplet and how the minimal detaching force per unit mass decreases with droplet size. We extract scaling relations that allow extrapolation of our findings to larger length scales that are not directly accessible by molecular models. We find that the volume of the residue on a fiber varies nonmonotonically with the detaching force, reaching the maximal size at an intermediate force and associated detachment time. The strength of this force decreases with the size of the drop, while the maximal residue increases with the droplet volume, V, sub-linearly, in proportion to the V^2/3. Second, we address the adhesion on conducting graphene. We improved the graphene model by incorporating the conductivity of graphene sheet using the fluctuating charge technique of Constant Potential Molecular Dynamics (CPMD). We evaluated the wettability by measuring the contact angle of cylindrical water drops on a conducting graphene sheet. We found that the CA of a water droplet on a graphene sheet supported by water is lower than in the absence of water under graphene. Our calculations reveal effective attractions between partial charges of equal sign across the conducting graphene sheet. Attractive correlations are attributed to the formation of the highly localized image charges on carbon atoms between the partially charged sites of water molecules on both sides of graphene. By performing additional computations with nonpolar diiodomethane, we confirm that graphene transmits both polar and dispersive interactions. These findings are important in applications including sensors, fuel cell membranes, water filtration, and graphene-based electrode material to enhance the supercapacitor performance. A challenge for future work concerns dynamic polarization response of wetted graphene at alternating (AC) field condition. Advisors/Committee Members: Neda Ojaghlou.

▼ Calcium oxalate crystals are found in kidney stones as either calcium oxalate monohydrate (COM) or calcium oxalate dihydrate (COD). COM crystals are the most abundant form as they are thermodynamically more stable than COD crystals under physiological conditions. Certain aspartic acid-rich molecules such as osteopontin (OPN) are known to affect stone formation by inhibiting COM and COD growth. We have studied COM {010} and COD {100} faces in the presence of OPN, poly-aspartic acid (poly-ASP) and synthetic peptides derived from OPN to investigate the inhibitor mechanism. We observed that poly-ASP preferentially inhibits one particular direction of {010} faces on COM crystals, creating “finger-like” features, while growth continues in other directions. We find that these features appear at a threshold concentration of poly-ASP that varies with the length of the polymer. Attempts to model the threshold concentration suggest that this is due to a competition between adsorption of polymer to already-pinned steps and removal of poly-ASP by desorption and possibly coverage by advancing steps between strongly pinned steps. Growth of {100} faces of COD crystals in the presence of synthetic peptides derived from OPN with different iso-electric points displayed varying levels of inhibition. The two principal directions of the elongated elliptical hillocks on {100} faces were inhibited to different degrees by the peptides. This preferential inhibition is most likely the result of different Ca2+ ion densities and structures of the two different step directions. The effects of imaging on the growth itself were studied for the case of COM growth in the presence of OPN. In the presence of OPN molecules, a continuously-scanned area showed faster growth relative to a larger area scanned less frequently. This enhanced vertical growth in the continuously-scanned area was found to vary with the OPN concentration and calcium oxalate supersaturation. We modeled this effect using a modified version of the Cabrera-Vermilyea model (1958), in which steps are pinned by adsorbed impurities, resulting in a decreased propagation speed due to the resulting curvature. In our case, we assume adsorption directly to steps, rather than to terraces as in the Cabrera-Vermilyea model.

▼ Excluded Volume (EV) and Hydrodynamic Interactions (HI) play a central role in static and dynamic properties of macromolecules in solution under equilibrium and nonequilibrium settings. The computational cost of incorporating HI in mesoscale Brownian dynamics (BD) simulations, particularly in the semidilute regime has motivated significant research aimed at development of high-fidelity and efficient techniques. In this study, I have developed several algorithms for the mesoscale bead-spring representation of a macromolecular solution in dilute and semidilute regimes. The Krylov subspace method enables fast calculation of single chain dynamics with simulation time scaling of O(Nb2) [order N subscript b squared], where Nb is the number of beads in the chain. For simulations of multichain systems, a matrix-free approach is implemented which leads to O(NlogN) scaling of simulation time, where N is the number of beads in the periodic box. The Krylov and predictor-corrector schemes are used to study the behavior of dilute solutions of high molecular weight flexible macromolecules, and in particular Polystyrene (PS). The influence of HI and EV on the extensional hardening of the macromolecular solutions is considered. It is demonstrated that the combination of HI and successive fine-graining results in a remarkable prediction of rheological properties of solutions containing 1.95, 3.9, and 10.2 million molecular weight PS. Further, a bead-spring model is developed to overcome the deficiencies of the current mesoscale worm-like chain models, i.e., to accurately describe the correlation along the backbone, segmental length, and the force-extension behavior even at the limit of 1 Kuhn step per spring. The new model is utilized to examine the relaxation and stretching behavior of linear and comb DNA molecules. The BD computational results are in good agreement with single molecule visualization experiments in a cross-slot device (planar extensional flow). For interacting multichain systems, the fidelity of the matrix-free algorithm is demonstrated by evaluating the asymptotic value of center of mass diffusivity at low concentrations and the radius of gyration as a function of number of beads in θ [theta] and good solvent conditions. Our results are consistent with blob theory, which is commonly used to describe the concentration dependence of polymer solution properties.

▼ Room temperature ionic liquids are an important class of materials due to their chemical tunability and numerous advantageous physicochemical properties. As a result, ionic liquids are currently being investigated for use in a wide array of chemical and electrochemical applications. Despite their great potential, however, the relationship between the chemical structure and physicochemical properties of ionic liquids is not well understood. To this end, this dissertation presents experimental studies of the reorientational structural dynamics and charge transport properties of a variety of room temperature ionic liquids using quasielastic light scattering spectroscopy and broadband dielectric spectroscopy. Studies of a series of 1-butyl-3-methylimidazolium based ionic liquids, in which the anion was systematically varied, have revealed that the anion chemical structure has a significant impact on the structural dynamics and charge transport properties of ionic liquids. As the anion becomes larger and more asymmetrical, ionic mobility increases strongly as a result of an increased fluidity. Surprisingly, the mole fraction of free ions remains unaffected by the anion chemical structure. The influence of cation chemical structure on the transport properties of ionic liquids was explored in a homologous series of tetra-alkylammonium based ionic liquids. It was found that pronounced chemical heterogeneity causes ionic liquids to exhibit complex and strongly heterogeneous molecular dynamics. Furthermore, when aliphatic side-groups of cations occupy a large liquid volume fraction, both the ion mobility as well as the mole fraction of free ions were found to decrease strongly as a consequence of pronounced nanophase segregation. The transport properties of a novel carboxylic acid-tertiary amine based protic ionic liquid were also studied in this dissertation. The structural dynamics and charge transport mechanism in this protic ionic liquid are surprisingly very similar to the aprotic ionic liquids, despite the fundamental differences in the intrinsic charge carrier. Through these comparative studies, this dissertation not only provides a fundamental understanding of the unique dynamical properties of room temperature ionic liquids, but it also elucidates the complex interrelationship between key chemical structure variations and molecular transport properties of these important materials.

▼ Mathematical theories reveal the fundamental physics involved in experimentalphenomena. Computer models of such theories are routinely used to corroborate or explain experiments and predict properties of chemical systems. Therefore, an important effort in computational chemistry is the development of more accurate and efficient chemical models. Current-generation models are only beginning to approach experimental-quality predictions of hydration free energies (HFEs).Using computations of quantum mechanical (QM) forces and classical simulations based on these forces, I investigate models to predict several properties of solutes and solutions. This dissertation is a collection of projects exemplifying methods used to gain insight into chemical systems. Simulations of bulk, supercooled, liquid water using a model based solely on QM data predict an exponential rise in the surface tension with increased supercooling, supporting the existence of a highly debated second phase of liquid water. A new method for computing static charges of atomic nuclei is derived, which offers a simple and physically sound method that can be used to investigate charge transfer in model systems and generate atomic charges for use in simulations. Formulae used to calculate HFEs and the assumptions under which they may be equated are investigated, demonstrating that, under physical conditions that validate ideal gas assumptions, theoretical and experimental HFE measurements should be directly comparable. This project also shows how to resolve disagreement between experimental and computational measurements made outside ideal conditions. Methods for developing custom, QM-based force fields (FFs) by Adaptive Force Matching are described, including specific details for FFs of aqueous methane, ethane, methanol, and ethanol. These FFs are used to predict HFEs and other properties in good agreement with experiments. These projects demonstrate the capability of computational methods to enhance scientific knowledge when carefully developed from sound theory. Using simple models constructed to reproduce the underlying QM characteristics of a system, classical simulations are able to accurately predict HFEs. Supplemental attachments to the dissertation include the first users’ manual for the CRYOFF software and a tutorial for using CRYOFF in Adaptive Force Matching.

▼ Water vapor is the most dominant greenhouse gas in Earth's atmosphere. It is highly variable and its variations strongly depend on changes in temperature. Atmospheric water vapor can be expressed as relative humidity (RH), the ratio of the partial pressure of water vapor in the mixture to the equilibrium vapor pressure of water over a flat surface of pure water at a given temperature. Liquid water can exist as super-cooled water for temperatures between 0C to -38C. Thus, RH can be measured either relative to water (RHw) or to ice (RHi). RHi measurements are important in the upper tropospheric region, where the temperature is always less than 0C, to study ice supersaturation (ISS) and its relation to the formation of cirrus clouds. I present three studies all using a mathematical scheme called the optimal estimation method (OEM). The OEM is an inverse method that determines the most probable state consistent with the measurements and a priori knowledge. These studies use parts of a large set of existing measurements from the Raman Lidar for Meteorological Observations (RALMO) instrument located at the meteorological observatory in Payerne, Switzerland. I first develop an OEM retrieval for temperature using RALMO's two pure rotational Raman (PRR) channel measurements. Retrieved temperatures show excellent agreement with coincident balloon-borne radiosonde measurements. A second OEM scheme is introduced to retrieve RHw directly from RALMO measurements of back-scatter due to water vapor and nitrogen. I validate the OEM retrievals developed for temperature and RHw. I then combine the OEM-retrieved temperature and RHw with data from the European Centre for Medium-Range Weather Forecasts Re-analysis (ERA5) to compute a new and improved temperature and relative humidity product. The retrieval is enhanced by assimilating it with the ERA5 data. The quality of the RHw retrievals from the assimilated OEM scheme greatly improves over retrievals which use less accurate a priori information. Thirdly, I retrieve RHi to detect ISS layers. I find the frequency of ISS layers in the free troposphere over Payerne to be about 27% using 82.5 hours of measurements.

▼ In this thesis, a new way of simulating a two-way coupling between a liquid crystal and an immersed object is proposed. It can be used for objects of various geometries and can be expanded to be used for an object of any geometry. Additionally, a simple yet effective model was suggested for calculations of transmitted light through a nematic liquid crystal sample. This model allowed us to clarify the behavior of a ferromagnetic disc in a nematic liquid crystal observed in experiments and incorrectly interpreted at that time. Our simulations have demonstrated the following: in the absence of external forces and torques, discs with homeotropic (perpendicular) anchoring align with their surface normal parallel to the director of the nematic liquid crystal. In the presence of a weak magnetic field, a ferromagnetic disc will rotate to equilibrate the elastic torque due to the distortion of the nematic director and the magnetic torque. When the magnetic field rotates the disc so that the angle between normal to the surface of the disc and director of the liquid crystal becomes greater than 90 degrees, the disc flips around the axis perpendicular to the rotation axis, thus resolving the distortion in the liquid crystal. An analysis of this behavior was performed in Chapter 3. In particular, we look at the impact of the disc thickness, and conditions on the edges of the object, on defect creation and the flipping transition. We also analyze the importance of backflow (i.e. coupling of tensor order parameter with velocity field). We also study the same system under the action of fast rotating weak magnetic fields, that demonstrates a different behavior: the disc avoids flipping via creation of two symmetric defects on the sides. Some results on disc pairs are presented in Chapter 4. Interactions between discs, their motion and final position strongly depend on the distance between them, and the magnitude and angular velocity of the rotating magnetic field. Depending on the initial configuration of the system, different stable structures of discs result.

▼ This dissertation introduces two statistical techniques to tackle high-dimensional data, which is very commonplace nowadays. It consists of two topics which are inter-related by a common link, dimension reduction. The first topic is a recently introduced classification technique, the weighted principal support vector machine (WPSVM), which is incorporated into a spatial point process framework. The WPSVM possesses an additional parameter, a weight parameter, besides the regularization parameter. Most statistical techniques, including WPSVM, have an inherent assumption of independence, which means the data points are not connected with each other in any manner. But spatial data violates this assumption. Correlation between two spatial data points increases as the distance between them decreases. However, under some conditions on the spatial point process, the WPSVM is still valid. Furthermore, through extensive simulations it has been shown that WPSVM performs better than other dimension reduction techniques. The main advantage of WPSVM comes from the fact that it can handle non-linear relationships. WPSVM is also applied to a rainforest dataset. The second topic talks about another recently introduced technique, joint-screening. Unlike the previous method, this works for ultra-high dimensional data (p >> n). Most existing variable screening methods fail to identify those marginally unimportant but jointly important genetic variables. The joint screening (JS) procedure screens all the covariates at the same time based on a criterion. In this way a subset of variables that are suspected to be highly associated with the outcome can be identified. One massive advantage of the JS procedure comes from the fact that it is computationally simple and easy to understand. The performance of the proposed JS procedure is evaluated via simulation studies and an application to the Genetics Analysis Workshop 20 data.

▼ Understanding a system as complex as the human brain is a very demanding task. Directly working with structural and functional neuroimaging data has led to most of the understanding we have gained about the human brain. However, performing only the direct statistical comparisons on the empirical function and the structure does not fully explain the observed long-range functional correlations. Therefore, implementations of mathematical models to gain further understanding of the relationship between the structure and function of the brain is critical. Additionally, spontaneous functions of the brain can only be predicted using computer simulated models; which will be pivotal for studying the patients with accidental brain injuries. Therefore, this research aims to present an optimized computer simulated model not only to further understand the structure-function relationship of the brain but also to predict the functional changes when anatomy is altered. Based on prior work, 2-dimensional classical Ising model stands out among the other models in modeling the functions of the brain due to its simplicity. Hence, a 2-dimensional Ising model was simulated on a structural connectome (generalized Ising model) that acts as a proxy for the anatomical connectivity in the brain. Simulations allowed the prediction of functional connectivity using the structure, at criticality. It also enabled the introduction of a novel methodology to calculate the ”dimensionality” of the brain. Our results showed the dimensionality of a healthy brain is two when it is defined using the information flow in the brain. Further research illustrated the dependency of dimensionality on the diffusion tractography method used to obtain the structural connectome. It was also concluded that an optimized generalized Ising model has to be simulated using a structural connectome generated by deterministic tractography to acquire the best predictions of empirical function. Additional investigations into a more generalized version of the Ising model—Potts model with different number of spin states—illustrated that increasing the number of spin states does not increase the predictability. It also supported the hypothesis that the model could be simulating the digital nature of direct neural activity rather than the indirect activity measured by brain imaging.

▼ Although many technical advancements have been made, neuroscientists still struggle to explain the underlying behaviour of how brain regions communicate with each other to form large-scale functional networks. functional Magnetic Resonance Imaging (fMRI) has been commonly used to investigate changes between brain regions over time using the Blood Oxygen Level Dependent (BOLD) signal. The goal of this thesis is to show the applicability of novel techniques and tools, such as the generalized Ising model (GIM) and the independent component graph analysis (GraphICA), to obtain information on the functional connectivity of populations with altered perception of consciousness. The GIM was used to model brain activity in healthy brains during various stages of consciousness, as induced by an anesthetic agent, propofol, in the auditory paradigm. GraphICA, a tool that combines ICA and graph theory was used to investigate the functional connectivity of resting state networks (RSNs) in patients with altered perception caused by tinnitus and in patients with altered states of consciousness caused by severe brain injury. For the tinnitus patients, we examined whether a correlation exists between tinnitus behavioural scores and functional brain connectivity of RSNs. Moreover, for the severely brain injured patients, a multimodal neuroimaging approach with hybrid FDG-PET/MRI was implemented to study the functional connectivity changes of the RSNs. The GIM simulated with an external field was able to model the brain activity at different levels of consciousness under naturalistic stimulation, at a temperature in the super critical regime. Further, a strong correlation was observed between tinnitus distress and the connectivity pattern within and between the right executive control network and the other RSNs. This suggests that tinnitus distress is the consequence of a hyperactive attention condition. A variability was observed in the appearance and temporal/spatial patterns of RSNs among the two resting state fMRI acquisitions acquired within the same scanning session of the severely brain injured patients. This suggests the need for new strategies to be developed in order to pick the best RSN from each acquisition. Overall, this work demonstrated that the GIM and GraphICA were promising tools to investigate brain activity of populations with altered perception of consciousness and in future can be extended to investigate different neurological populations.

▼ This dissertation presents work that increases our understanding of the effects of composition and architecture on copolymer structure and dynamics and how they affect material diffusion between filaments in a 3D printed model. Copolymers are polymer chains made up of at least two different monomers. The ordering and arrangement of the two monomer species within a copolymer can have drastic effects on the behavior and properties of the copolymer. The first chapter of this dissertation examines how the copolymer composition affects the structure and dynamics of the chain in a homopolymer blend. This study used a modified Monte Carlo BFM to simulate random polystyrene(PS)-polymethymethacrylate(PMMA) copolymers in a PMMA matrix. The results suggest that the faster moving PS segments in the copolymer chain dominate the chain’s motion. However, concentration fluctuations in the local volume around segments of the chain ultimately slow the chain down. This work sheds light into why a randomly distributed copolymer will move faster than a di-block copolymer of the same monomer composition. The next project focused on the effect of copolymer architecture on the structure and dynamics of branched polymers in a homopolymer matrix using a Monte Carlo simulation. In these simulations, branched polymer consisted of a backbone and the side-chains being unlike monomer species. The number and the molecular weight of the branches was varied to study the effects of branch packing densities on homopolymer copolymer comb structure and motion. Additionally, the temperature varied to determine the effect of available thermal energy on each architectural copolymer configuration. The results of this project concluded that the structure and motion of a branched polymer are a result of the balance in the thermodynamic environment surrounding the copolymer. Finally, the effect of inter-filament heat and copolymer diffusion on inter-filament bonding in 3D printed part was examined. In this study the importance of thermal history in the print environment was determined quantitatively and its effect on the adhesion between acrylonitrile-butadiene-styrene (ABS) copolymer filaments was probed. Additionally, the interface between ABS filaments was improved using a chemical cross-linker. These studies provide insight into improving the mechanical strength of 3D printed parts.
