▼ An increasingly common approach to treating severe to profound hearing loss in children and adults is cochlear implantation, with over 219,000 users worldwide. While most cochlear implant (CI) users achieve high levels of speech understanding in quiet, many continue to struggle with speech in the presence of background noise and music appreciation. One working hypothesis is that these deficits are related to impaired spectral resolution with CIs. Both device-related and patient-related factors are thought to contribute to impaired spectral resolution. This series of experiments were conducted to identify ways to improve spectral resolution in individuals using two approaches. First, a device-centered approach was used with a focused stimulus configuration to determine if it was possible to identify poorly-functioning CI channels with the hopes of improving how CIs are mapped clinically, using a behavioral (experiment 1) and an objective measure (experiment 2). Given that spectral resolution is likely not entirely related to device factors, and not all aspects of the device are modifiable or controllable, we also set out to determine if we could improve the implant user's ability to make use of the information they receive with their implant through auditory training (experiment 3). The results of the first two experiments demonstrated that problem channels can be identified using behavioral (single-channel thresholds and tuning curves) and objective measures (EABR). Using a single-subject design, we also showed that it is possible to alter perception of frequency through auditory training. All trained subjects improved on tests of speech in noise, but improvements did not generalize to tests of speech in quiet, music perception, or quality of life. The pattern of learning suggests that the improvements cannot be entirely explained by improved spectral resolution, and motivates future directions aimed at understanding what mechanism of action in the training paradigm contributed to improved speech reception in noise.

▼ Spectral analysis of signals, or the problem of spectral estimation revolves around estimating the distribution of power over frequency of a random signal. It has useful applications in various fields of study (including Speech analysis, Medicine, RADAR and SONAR) due to the fact that the frequency content of an observed signal can provide very useful information in these fields. A well known method for estimating the spectral content of a signal is the Periodogram (developed by Arthur Schuster), which is a data-independent method of estimation. This method is based on computing the Fourier transform of the signal which can be computed efficiently using the Fast Fourier Transform (FFT) algorithm. This method however, is limited by relatively poor resolution and high side-lobes, which can lead to degradation in retrieval of the desired information present within the signal. Data-dependent (adaptive) techniques both non-parametric and parametric can offer superior performance over data-independent methods like the periodogram at a cost of increased computational complexity. These data-adaptive approaches however, can lead to improved spectral resolution and lower side-lobes, which can reveal more information about the signal under study. These advantages have led to increased interest in data-adaptive approaches to the problem of spectral estimation. This dissertation proposal revolves around applying robust adaptive techniques to real-world problems to achieve superior performance. In Chapter 2, adaptive techniques are used in the problem of frequency estimation (harmonic retrieval) in the presence of strong interference. The focus is on the problem of digital audio forensics, where the goal is to extract the embedded network frequency from a digital recording and compare it to a known database for digital audio verification. In the presence of significant interference, extracting the network frequency using the standard method (Periodogram) is difficult due to poor resolution and high-sidelobes. We therefore use a robust adaptive algorithm (Iterative Adaptive Approach) to improve the spectral resolution and suppress side-lobes hence effectively separating the network frequency from interference. A frequency tracking method based on dynamic programming is used in addition to this data-adaptive method to extract the Network frequency accurately and hence provide more reliability for the verification process compared to the current standard. In Chapter 3, we once again apply an adaptive technique for harmonic retrieval. The goal here is to effectively suppress Radio Frequency Interference (RFI) picked up by an Ultra-wideband (UWB) RADAR (currently being built by the Army Research Lab (ARL) for landmine detection) which samples its returned signals using an equivalent sampling scheme. This equivalent sampling scheme makes RFI suppression difficult (due to under-sampling (aliasing)). The current method for RFI suppression for this UWB RADAR is simply averaging multiple realizations of the measured data.

▼ The ability to perceive speech is related to the listener's ability to differentiate among frequencies (i.e. spectral resolution). Cochlear implant users exhibit variable speech perception and spectral resolution abilities, which can be attributed at least in part to electrode interactions at the periphery (i.e. spatial resolution). However, electrophysiological measures of peripheral spatial resolution have not been found to correlate with speech perception. The purpose of this study was to systematically evaluate auditory processing from the periphery to the cortex using both simple and spectrally complex stimuli in order to better understanding the underlying processes affecting spatial and spectral resolution and speech perception. Eleven adult cochlear implant users participated in this study. Peripheral spatial resolution was assessed using the electrically evoked compound action potential (ECAP) to measure channel interaction functions for thirteen probe electrodes. We evaluated central processing using the auditory change complex (ACC), a cortical response, elicited with both spatial (electrode pairs) and spectral (rippled noise) stimulus changes. Speech perception included a vowel-discrimination task and the BKB-SIN test of keyword recognition in noise. We varied the likelihood of electrode interactions within each participant by creating three experimental programs, or MAPs, using a subset of seven electrodes and varying the spacing between activated electrodes. Linear mixed model analysis was used to account for repeated measures within an individual, allowing for a within-subject interpretation. We also performed regression analysis to evaluate the relationships across participants. Both peripheral and central processing abilities contributed to the variability in performance observed across CI users. The spectral ACC was the strongest predictor of speech perception abilities across participants. When spatial resolution was varied within a person, all electrophysiological measures were significantly correlated with each other and with speech perception. However, the ECAP measures were the best single predictor of speech perception for the within-subject analysis, followed by the spectral ACC. Our results indicate that electrophysiological measures of spatial and spectral resolution can provide valuable information about perception. All three of the electrophysiological measures used in this study, including the ECAP channel interaction functions, demonstrated potential for clinical utility.

▼ The major challenges in hyperspectral (HS) imaging and data analysis are expensive sensors, high dimensionality of the signal, limited ground truth, and spectral variability. This dissertation develops and analyzes machine learning based methods to address these problems. In the first part, we examine one of the most important HS data analysis tasks-vegetation parameter estimation. We present two Gaussian processes based approaches for improving the accuracy of vegetation parameter retrieval when ground truth is limited and/or spectral variability is high. The first is the adoption of covariance functions based on well-established metrics, such as, spectral angle and spectral correlation, which are known to be better measures of similarity for spectral data. The second is the joint modeling of related vegetation parameters by multitask Gaussian processes so that the prediction accuracy of the vegetation parameter of interest can be improved with the aid of related vegetation parameters for which a larger set of ground truth is available. The efficacy of the proposed methods is demonstrated by comparing them against state-of-the art approaches on three real-world HS datasets and one synthetic dataset. In the second part, we demonstrate how Bayesian optimization can be applied to jointly tune the different components of hyperspectral data analysis frameworks for better performance. Experimental validation on the spatial-spectral classification framework consisting of a classifier and a Markov random field is provided. In the third part, we investigate whether high dimensional HS spectra can be reconstructed from low dimensional multispectral (MS) signals, that can be obtained from much cheaper, lower spectral resolution sensors. A novel end-to-end convolutional residual neural network architecture is proposed that can simultaneously optimize both the MS bands and the transformation to reconstruct HS spectra from MS signals by analyzing a large quantity of HS data. The learned band can be implemented in sensor hardware and the learned transformation can be incorporated in the data processing pipeline to build a low-cost hyperspectral data collection system. Using a diverse set of real-world datasets, we show how the proposed approach of optimizing MS bands along with the transformation rather than just optimizing the transformation with fixed bands, as proposed by previous studies, can drastically increase the reconstruction accuracy. Additionally, we also investigate the prospects of using reconstructed HS spectra for land cover classification. Advisors/Committee Members: Eli Saber.

▼ Nuclear Magnetic Resonance spectroscopy (NMR), as the prime technique for efficient and rapid screening of the compounds in chemical samples, represents the nuclei in molecules as resonance peaks in the spectrum. The peaks are regarded as the “fingerprints” of the chemical components in the molecules, providing necessary information for researchers to elucidate the structure of the chemicals.The time domain signal obtained in the modern NMR experiment can ideally be modelled as the superposition of multiple damped complex exponentials in additive Gaussian noise. For obtaining key information of the chemical compound being analysed, all the useful components should be successfully detected and algorithms should be applied to estimate their parameters. However, practical features including large signal size, unknown number of components, the existence of weak and overlapped peaks, and signal distortions caused by experimental artefacts, make these tasks hard to achieve. In this thesis, we focus on finding effective methods for the signal detection and parameter estimation problems for NMR signals that are capable of handling the practical signal features.To tackle the signal detection problem, we develop the Localised Capon spectral Estimator (LoCapE), which is a high resolution spectral estimator in selected regions of the spectrum. Without a priori knowledge on the number of components, LoCapE is capable of resolving extremely closely spaced components in experimental NMR signals that cannot be separated by the Discrete Fourier Transform (DFT).In terms of the parameter estimation problem, we put forward several novel frequency domain interpolation algorithms for efficiently estimating parameters of signals related to the ideal NMR signal model. We first present the 2-D version of the parameter estimation algorithm proposed by Aboutanios and Mulgrew (the A&M algorithm), for estimating the frequencies/parameters of single 2-D exponentials in noise. This is followed by the presentation of the Iterative Windowed A&M (IWAM) algorithm for the estimation of the frequency and damping factor of a 1-D damped exponential in noise, that is robust when the signal has a long noisy tail. By combining with a leakage subtraction scheme, the A&M algorithm and the IWAM algorithm are then extended to the Multi-tone A&M (MAM) algorithms which address the parameter estimation of ideal 1-D NMR signals. Theoretical analysis and simulation results show that all the proposed parameter estimators are able to achieve performance that is extremely close to the Cramer-Rao Lower Bound (CRLB).To achieve simultaneous signal detection and parameter estimation of actual NMR signals, the IWAM algorithm is finally incorporated with a generalised lineshape model and a least squares lineshape adaptation scheme. This results the Peak Extraction using Adaptive Lineshape (PEAL) algorithm which can obtain reliable component extraction and accurate parameter estimation on experimental proton NMR datasets with arbitrary lineshape distortion.

▼ There has been significant progress in the optical resolution of microscopes over the last two decades. However, the majority of currently used methods (e.g. STED, PALM, STORM) have a number of drawbacks, including high intensities of light that result in damage to living specimens in STED, and long data acquisition time leading to limitations on live-cell imaging. Therefore, there is a niche for faster image acquisition at lower intensities while maintaining resolution beyond the diffraction limit. Here, we have developed a new methodology - Quantum Dot-based Optical Spectral Separation (QDOSS) - which relies on using Quantum Dots (QDs) as fluorophores, and on their separation and localisation based on their spectral signatures. We utilise the key advantages of QDs over the usual organic fluorophores: broad excitation, narrow emission spectra and high resistance to photobleaching. Besides, since QDOSS is based on spectral differences for separation, QDs can be deterministically localised in a relatively short time - milliseconds and, potentially, microseconds. Last but not least, QDOSS is suitable for obtaining super-resolution images using a standard confocal fluorescence microscope equipped with a single laser excitation wavelength and capable of spectral signal separation (e.g. Leica TCS SP series or Zeiss LSM series). First, we demonstrated resolution down to 60 nm using triangular DNA origami as a reference. Furthermore, we labelled and imaged the alpha-tubulin structure in HEK293T cells. We showed that using a mixture of standard off-the-shelf QDs of different sizes, resolution down to 40 nm could be achieved via spectroscopic separation of QDs. Finally, we demonstrated that QDOSS could also be used for multicolour imaging of synaptic proteins distributed around synapsis in neurons within diffraction limit. All in all, we believe that these features of QDOSS make it a potential method for long-term live super-resolution imaging, which is going to have a high impact in biological sciences.

Une perte auditive neurosensorielle est généralement associée à uneréduction de l’intelligibilité de la parole, et ce tout particulièrement dans le bruit.Les contributions respectives d’une réduction de l'audibilité et de déficitssupraliminaires sont encore débattues.L'objectif principal de cette thèse était d'évaluer l'effet spécifique desdéficits supraliminaires sur l’intelligibilité de la parole. L'effet de l'audibilité étaitcontrôlé en mesurant l’intelligibilité de signaux de parole sans signification filtrésdans les régions basses et moyennes fréquences au sein desquelles la détection desons purs était normale chez des auditeurs malentendants présentant par ailleursune perte auditive en hautes fréquences. Dans ces régions fréquentielles oùl’audibilité est supposée normale, des déficits d'intelligibilité de la parole légers àsévères ont été observés dans le silence comme dans le bruit chez les auditeursmalentendants. Les déficits étaient similaires dans les bruits masquantstationnaires et fluctuants. Ces résultats démontrent l’influence des déficitsauditifs supraliminaires sur l’intelligibilité de la parole.Le second objectif de cette thèse était d'étudier l'origine de ces déficitssupraliminaires. Les résultats indiquent qu’une réduction de la sélectivitéfréquentielle cochléaire ne peut pas expliquer entièrement les déficitsd’intelligibilité de la parole des auditeurs malentendants. L'influence de lasensibilité à la structure temporelle fine reste incertaine

Speech intelligibility is reduced for listeners with sensorineural hearingloss, especially for speech in noise. The extent to which this reduction is due toreduced audibility or to supra-threshold deficits is still debated.The main goal of this PhD work was to investigate the specific influenceof supra-threshold deficits on speech intelligibility. The effect of audibility wascontrolled for by measuring speech intelligibility for hearing-impaired listenersusing nonsense speech signals filtered in low- and mid-frequency regions wherepure-tone sensitivity was normal. Hearing-impaired listeners with hearing loss inhigh-frequency regions showed mild to severe intelligibility deficits for speechboth in quiet and in noise in these frequency regions of normal audibility. Similardeficits were obtained for speech in steady and fluctuating masking noises. Thisprovides additional evidence that speech intelligibility may be strongly influencedby supra-threshold auditory deficits.The second aim of this PhD work was to investigate the origin of thesesupra-threshold deficits. Results showed that reduced frequency selectivity cannotentirely explain the speech intelligibility deficits of the hearing-impaired listeners.The influence of temporal fine structure sensitivity remained unclear

▼ Living elasmobranchs occupy every major aquatic ecosystem throughout the world (Compagno 2003; Compagno et al. 2005). Sensory ecology can be a good determinant in comprehending the processes occurring between an organism and its natural environment (Weissburg and Browman 2005). By utilizing ecophysiological tools, insight into the adaptive responses of the sensory systems to their ever-changing ecological niche can help explain behavioral and life history characteristics (Hueter 1991; Litherland 2009). Aquatic animals show structural and physiological adaptations in their visual sense specific to the ecological requirements of their habitat (Hart et al. 2004), implying that vision is an important modality. The visual system of the smooth dogfish (Mustelus canis, family Triakidae) was examined using corneal electrophysiological methods to determine the visual spectral range, irradiance sensitivity, and speed of vision (flicker fusion frequency, FFF). The smooth dogfish, a shallow water bottom feeder inhabiting inshore waters along the eastern United States, was found to be extremely sensitive to dim light (-3.1- 0.1 log light intensity), and have a slow FFF (13 Hz), thus being well adapted to the scotopic conditions of the turbid coastal inshore waters. This prompted a second set of experiments focusing on the chromatic adaptations of the photoreceptor cells and retina function following light adaptation. Light adaptation increased the photopic threshold by 2.0 log light units of intensity (LLI). However, the temporal resolution was not dramatically increased (to 17 Hz), indicating that the retinal integration time is very slow for this species under all circumstances. The spectral sensitivity peak for M. canis (470 nm) was found to be significantly blue-shifted in comparison to other members of the Triakidae family (Crescitelli et al. 1995; Sillman et al. 1996). Smooth dogfish appear to forgo high spatial and temporal resolution for the enhancement of photon capture. The sandbar shark inhabits the same inshore estuaries during the summer months but has a visual system with a higher temporal resolution (FFF, 54 Hz) and a brighter photopic threshold (1.2 LLI-50% max) (Litherland 2009). Furthermore, other elasmobranch or telelost species inhabiting similar photic environments also exhibit faster temporal resolution; little skate (FFF, 30 Hz), weakfish (FFF, 40 Hz), red drum (FFF, 50 Hz), spotted sea trout (FFF, 60 Hz), and Atlantic croaker (FFF, 58 Hz) (Horodysky et al. 2008; McComb et al. 2010). Coastal seas tend to contain more dissolved organics and particulates than the clear oceanic waters of the epipelagic and pelagic zones (McFarland 1986), therefore the retina of smooth dogfish has adapted to be extremely sensitive to dim light, has a long integration time, a low flicker fusion frequency and temporal resolution, and retinal cells that are able to adjust to changing light conditions. All of these factors contribute to the visual system to provide optimal visual ability to enable smooth dogfish to accurately…

▼ Le sondeur hyperspectral infrarouge IASI, dont le premier modèle vole depuis 2006 sur le satellite défilant météorologique Metop-A, a déjà conduit a des retombées scientifiques très spectaculaires, en prévision météorologie et pour l’étude de la composition atmosphérique et du climat. Les mesures du sondeurs sont toutefois largement sous exploitées en grande partie du a la présence des nuages dans l’atmosphère. Ces derniers interagissent avec le rayonnement incident de façon hautement non-linéaire rendant le traitement de la mesure du sondeur bien plus complexe, voire parfois rédhibitoire pour accéder depuis l’espace aux propriétés des couches atmosphériques situées au-dessus du nuage, mais également en dessous dans le cas de semi-transparence. Cependant, au vue de la quantité d’informations potentielles qu’offre les sondeurs, la communauté scientifique s’intéresse de près a l’exploitation des radiances nuageuse, c’est dans ce cadre que s’inscrivent les travaux de recherche de cette thèse. Nous proposons d’étudier deux schémas nuageux radicalement différents : la clarification nuageuse et un schéma permettant de simuler la radiance nuageuse en utilisant les propriétés optique et microphysique des nuages. La première de ces méthodes, initiée par Smith et al. (1968), permet sous certaines conditions, de faire abstraction du nuage dans le pixel IASI. La méthode est basée sur l’algorithme du logiciel Scenes Heterogenes du CNES. Apres une première étape de validation, les performances de la méthode sont évaluées a travers la quantité d’information indépendante qu’offre la clarification par rapport a une chaine de traitement des radiances nuageuses mise en place au CMS. Les résultats sont favorables à la méthode testée permettant de traiter les couches atmosphériques situées sous le nuage, possédant donc une quantité plus importante. Cependant la clarification repose a la fois sur une hypothèse forte d’homogénéité atmosphérique et ne s’applique qu’à 15% des situations nuageuses. La seconde méthode est une simulation de la radiance nuageuse par des modèles de transfert radiatif rapides utilisant les propriétés optique et microphysique du nuage. Cette méthode présente l’avantage majeur d’utiliser les mêmes profils nuageux que ceux produits par les modèles de prévision numérique, laissant entrevoir l’assimilation de ces profils à partir de la mesure IASI. Cependant, l’utilisation de ces modèles de transfert radiatif rapide dans le cadre d’une assimilation de données n’en est encore qu’à ces prémices, très peu d’études ont été menées sur ce sujet. Nous proposons une étude en trois étapes permettant une utilisation en opérationnel de ces modèles de transfert radiatif. La première étape est une compréhension des modèles et de leur validité en réalisant quelques études de cas s’appuyant sur la campagne de mesures de Lindenberg. Ensuite, dans le cadre de la campagne ConcordIasi, une statistique est réalisée mettant en place des filtrage pour sélectionner uniquement les profils nuageux cohérent avec l’observation IASI. La dernière… Advisors/Committee Members: Rabier, Florence (thesis director), Lavanant, Lydie (thesis director).

▼ Traditional spectral imaging approaches require scanning the scene to construct a 3-dimensional data cube. These methods experience low sensing speed and the resulting amount of data makes its management very challenging. In contrast, compressive spectral imaging (CSI) systems capture the spatial and spectral information of the scene at once, in a 2-dimensional set of coded projections. Compressed sensing (CS) reconstruction algorithms are then used to reconstruct the underlying spectral 3D data cube from an underdetermined system of linear equations. In general, CSI projections consist on integrating encoded and dispersed versions of the input source. Thus, different optical configurations yield different sampling strategies and reconstruction performance. More specifically, image reconstruction quality depends on the employed coding of the input scene. ☐ This dissertation aims at exploring different optical coding strategies in CSI systems. A first strategy considers CSI architectures with coded apertures as the coding element. The structure of the coded apertures is crucial inasmuch as they determine the entries of the sensing matrix. Given that conventional coded aperture patterns are selected at random, leading to suboptimal reconstruction solutions, the proposed strategy exploits the restricted isometry property of the sensing matrix and its incoherence with respect to the sparse representation basis to optimize the coded aperture ensemble. ☐ On the other hand, a different coding strategy is introduced motivated by the complicated optical paths of state-of-the-art CSI systems that compromise their portability. In this case, we propose a new compact CSI architecture that exploits the benefits of colored mosaic FPA detectors and the compression capabilities of CSI sensing techniques. The optical and the mathematical models of the explored encoding strategies are presented along with testbed implementations of the systems. Simulations and experimental data evaluate the accuracy of the proposed strategies. ☐ In addition to the optical coding strategies, this dissertation studies the multiresolution (MR) reconstruction problem in compressive spectral imaging. To date, the common CSI reconstruction framework has focused on obtaining an approximation of the underlying spatial and spectral information of a scene from a set of coded projections, where the resolution of the reconstruction is as high as the measurements allow. Even though CSI enables fast multiplexed sensing, the complexity of the inverse problem depends on the spatial and spectral resolution of the data to be recovered. Motivated by such cases where a fast preview reconstruction is often desirable, we propose a multi-resolution reconstruction scheme for CSI that enables the sequential recovery of multiple versions of the same data cube at different spatial resolutions. Simulations are developed to analyze the performance of the proposed MR reconstruction model. Advisors/Committee Members: Arce, Gonzalo R.Arguello, Henry.

▼ Dark matter in the Milky Way could potentially be made of axions. If so, these axions would be detectable on Earth using an axion Haloscope. A search of this nature has been performed by the Axion Dark Matter eXperiment (ADMX). The high resolution (HR) data acquisition channel employed by ADMX is capable of searching for populations of non-virialized axions which are characterized by very low velocity dispersions. These populations are expected to lend structure to the Milky Way halo in the form of degenerate yet discrete flows. The motivations for dark matter, axions as a dark matter candidate, and halo structure caused by non-virialized dark matter are considered, as are their expected properties. These properties guide the direction of the analysis of HR data. Details of the experimental apparatus are examined, and any analysis-limiting factors are noted. A discussion of axion signal properties follows, including the expected effects of signal modulation. Data from the HR channel is analyzed at multiple resolutions, with each resolution corresponding to a maximum velocity dispersion for dark matter axions. For each resolution, the data are corrected for systematic errors and searched for peaks above a candidate threshold in the thermal noise power spectrum. Frequency coincidence is looked for among all candidate signals at a given resolution, with an allowance made for signal modulation due to terrestrial motion. Failure of a signal to be persistent, i.e. coincident in the majority of allowable power spectra, discounts it as being a real axion signal. No candidate signals have shown statistically significant persistence over the frequency range of 812 to 892 MHz. This corresponds to a mass range of 3.36 µeV to 3.69 µeV. Exclusion limits are placed on the local density of non-virialized axions in this range. Lastly, hardware upgrades and changes to the search algorithm are considered as means of improving and/or expanding upon these limits.

▼ For cochlear implant (CI) listeners, poorer than normal speech recognition abilities are typically attributed to degraded spectral acuity. However, estimates of spectral acuity have most often been obtained using simple (tonal) stimuli, presented directly to the implanted electrodes, rather than through the speech processor as occurs in everyday listening. Further, little is known about spectral acuity for dynamic stimuli, as compared to static stimuli, even though the perception of dynamic spectral cues is important for speech perception. The primary goal of the current study was to examine spectral acuity in CI listeners, and a comparison group of normal hearing (NH) listeners, for both static and dynamic stimuli presented through the speech processor. In addition to measuring static and dynamic spectral acuity for simple stimuli (pure tones) in Experiment 1, spectral acuity was measured for complex stimuli (synthetic vowels) in Experiment 2, because measures obtained with speech-like stimuli are more likely to reflect listeners’ ability to make use of spectral cues in naturally-produced speech. Sixteen postlingually-deaf, adult CI users and sixteen NH listeners served as subjects in both experiments. In Experiment 1, frequency discrimination limens (FDLs) were obtained for 1.5 kHz reference tones, and frequency glide discrimination limens (FGDLs) were obtained for pure-tone frequency glides centered on 1.5 kHz. Glide direction identification thresholds (GDITs) were also measured, in order to determine the amount of frequency change required to identify glide direction. All three measures were obtained for stimuli having both longer (150 ms) and shorter (50 ms) durations. Spectral acuity for dynamic stimuli (FGDLs, GDITs) was poorer than spectral acuity for static stimuli (FDLs) for both listener groups at both stimulus durations. Stimulus duration had a significant effect on thresholds in NH listeners, for all three measures, but had no significant effect on thresholds in CI listeners for any measure. Regression analyses revealed no systematic relationship between FDLs and FGDLs in NH listeners at either stimulus duration. For CI listeners, the relationship between FDLs and FGDLs was significant at both stimulus durations, suggesting that, for tonal signals, the factors that determine spectral acuity for static stimuli also largely determine spectral acuity for dynamic stimuli. In Experiment 2, estimates of static and dynamic spectral acuity were obtained using three-formant synthetic vowels, modeled after the vowel /^/. Formant discrimination thresholds (FDTs) were measured for changes in static F2 frequency, whereas formant transition discrimination thresholds (FTDTs) were measured for stimuli that varied in the extent of F2 frequency change. FDTs were measured with 150-ms stimuli, and FTDTs were measured with both 150-ms and 50-ms stimuli. For both listener groups, FTDTs were similar for the longer and shorter stimulus durations, and FTDTs were larger than FDTs at the common duration of 150 ms. Measures from…

▼ We present a novel methodology to characterize and quantify the Mitral Valve (MV) geometry and physical attributes in a multi-resolution framework. A multi-scale decomposition was implemented to model the MV geometry by using superquadric shape primitives and spectral reconstruction of the finer-scale geometric details. Superquadrics provide a basis to normalize the size and approximate a basic model of the MV geometry. The point-wise difference between the original geometry and the superquadric model denotes the finer-scale geometric details, which can be modeled as a scalar attribute for the MV model development. The additive decomposition of the basic MV geometry from geometric details (attributes) allows recovering the actual geometry by superposition of the superquadric approximation and the finer-details model. We implemented a lasso optimization algorithm to perform spectral analysis and develop the Fourier reconstruction of the geometric details. The spectral modeling enabled us to resample the geometric details or use spectral filters in order to adjust the spatial resolution in the model reconstruction. It also provides the basis to control the level of detail in the final model reconstruction by applying low-pass filters in the frequency domain. The higher-order attributes such as internal fiber architecture can be integrated with the geometric models using the same framework. We applied our pipeline to create models of three ovine MVs based on computed-tomography 3D images with micrometer resolution. We were able to quantify the MV leaflet geometry, reconstruct models with custom level of geometric details, and develop medial representation of the MV leaflet structure. The results show that our methodology for geometry analysis provides a basis for assessing patient-specific geometries and facilitates developing population-averaged models. Ultimately, this approach allows building personalized image-based computational models for medical device design and surgical treatment simulations. Advisors/Committee Members: Sacks, Michael S.

Les propriétés optiques de nanotubes de carbone sont décrites idéalement parla physique d’un objet unidimensionnel, donnant lieu notamment à l’apparition des excitons pour décrire les transitions optiques de ces objets. Les expériences d’optique(émission, absorption) réalisées sur ces objets à température ambiante et sur des ensemble d’objets ont permis de confirmer les prédictions théoriques basées sur la physique des objets 1D. Mais à température cryogénique et à l’échelle de l’objet unique,les propriétés optiques observées expérimentalement sont systématiquement très éloignées de celles d’un objet 1D. On peut notamment citer l’apparition de propriétés comme l’émission de photons uniques, qui a largement contribué à l’intensification de la recherche sur ces objets pour des applications en photonique quantique. Ces propriétés sont attribuées à la localisation des excitons le long de l’axe des nanotubes dans des puits de potentiel créés aléatoirement par l’interaction des nanotubes avec leur environnement. Les propriétés optiques sont alors proches de celles des objets0D, et sont fortement modulées par l’environnement. Les mécanismes et l’origine de la localisation et la connaissance physique de ces puits sont encore très limités. Ce travail montre d’une part le développement d’une technique d’absorption sur objet individuel et la caractérisation de sa sensibilité, et d’autre part l’étude statistique de l’émission de nanotubes à température cryogénique. Les résultats obtenus par une technique de super-résolution couplée à une imagerie hyper-spectrale montrent les grandeurs caractéristiques des puits de potentiels au sein de nanotubes individuels.Un dispositif expérimental de photoluminescence résolue en excitation implémenté au cours de ce travail a également montré une modification de l’état excitonique fondamental par l’environnement, avec l’apparition d’une discrétisation spatiale et spectrale de l’état fondamental délocalisé en une multitude d’états localisés.

The optical properties of carbon nanotubes are ideally described by the physicsof a one-dimensional object, giving rise in particular to the emergence of excitons todescribe the optical transitions of these objects. The optical experiments (emission,absorption) carried out on these objects at ambient temperature and on ensemblesconfirm the theoretical predictions based on the physics of 1D objects. But atcryogenic temperature and at the single emitter scale, the optical properties observedexperimentally are systematically different from those of a 1D object. One can citethe emergence of properties such as photon antibunching, which largely contributed tothe intensification of research on these objects for applications in quantum photonics.These properties are attributed to the localization of excitons along the nanotube axisin local potential wells (traps) created randomly by the interaction of nanotubes withtheir environment. The optical properties are then close to those of 0D objects, andare strongly modulated by the environment. The mechanisms and…
