description: This paper deals with products and ratios of average characteristic polynomials for unitary ensembles. We prove universality at the soft edge of the limiting eigenvalues' density, and write the universal limit in function of the Kontsevich matrix model ("matrix Airy function", as originally named by Kontsevich). For the case of the hard edge, universality is already known. We show that also in this case the universal limit can be expressed as a matrix integral ("matrix Bessel function") known in the literature as generalized Kontsevich matrix model.

description: Code snippet with the implementation of the analysis selection at truth-level
description: CERN-LHC. The results of a search for the direct pair production of stops, the supersymmetric partner of the top-quark, in final states with one isolated electron or muon, several energetic jets, and missing transverse momentum are reported. The search uses data from pp collisions delivered by the Large Hadron Collider in 2015 and 2016 at a center-of-mass energy of 13 TeV and recorded by the ATLAS detector, corresponding to an integrated luminosity of 36.1/fb. A wide range of signal scenarios with different mass splittings between the stop, the lightest neutralino and possible intermediate gauginos or higgsinos is considered, including cases where the W-bosons or the top-quarks are off-shell. The analysis also targets the production of dark matter in association with a pair of top-quarks using the same final state. No significant excess over the Standard Model prediction is observed. The null results are used to set exclusion limits at 95% confidence level in several benchmark models, which reach up to a stop mass of 940 GeV. Stringent exclusion limits are also derived for all other considered stop decay scenarios, and upper limits are set on the visible cross-section for processes beyond the Standard Model.

description: Quasi-elastic electron scattering on the deuteron is a benchmark reaction to test our understanding of deuteron structure and the properties and interactions of the two nucleons bound in the deuteron. The experimental data presented here can be used to test state-of-the-art models of the deuteron and the two-nucleon interaction in the final state after two-body breakup of the deuteron. Focusing on polarization degrees of freedom, we gain information on spin-momentum correlations in the deuteron ground state (due to the D-state admixture) and on the limits of the Impulse Approximation (IA) picture as it applies to measurements of spin-dependent observables like spin structure functions for bound nucleons. We measured the beam-target double spin asymmetry for quasi-elastic electron scattering off the deuteron at several beam energies using the CEBAF Large Acceptance Spectrometer (CLAS) at the Thomas Jefferson National Accelerator Facility. The deuterons were polarized along (or opposite to) the beam direction. The double spin asymmetries were measured as a function of photon virtuality , missing momentum, and the angle between the (inferred) "spectator" neutron and the momentum transfer direction. The results are compared with a recent model that includes Final State Interactions (FSI) using a complete parameterization of nucleon-nucleon scattering, as well as a simplified model using the Plane Wave Impulse Approximation (PWIA). We find overall good agreement with both the PWIA and FSI expectations at low to medium missing momenta, including the change of the asymmetry due to the contribution of the deuteron D-state at higher momenta. At the highest missing momenta, our data clearly agree better with the calculations including FSI.

Effect of Fiber Reinforcement and Early-Age Elastic Properties on Fatigue in PCC Pavements
Creators: name: Bassim, Raymond
Publisher: name: University of Illinois at Chicago
Year: 2019
Subjects: Uncategorized

description: Transportation agencies and state departments of transportation are facing increased traffic volumes and more congested work schedules in Portland Cement Concrete (PCC) construction and rehabilitation projects. Consequently, the decision for early opening traffic (EOT) becomes a major concern for pavement engineers seeking to limit roadway closure times and without compromising the structural integrity of the newly paved PCC sections. Additionally, this engineering challenge is amplified in high traffic zones and during cold weathering conditions. Current roadway specifications stipulate conservative reference compressive and flexural concrete strengths at the stage EOT. These rigorous strength figures are equivalent to closure times that can reach up to 28 days when strength monitoring or measurement is not achievable. In this context, early-age crack initiation in plain concrete applications such as PCC pavements consequently leads to uncontrolled structural failure and durability performance issues such as spalling, internal crack growth, and major slab breaks. This issue motivates the need to optimize EOT regulations in order to ensure long-term pavement serviceability and to decrease rehabilitation expenses throughout pavement service life. Accordingly, a thorough experimental program was conducted to evaluate the efficiency of strength monitoring techniques and to describe the fatigue performance of plain and fiber-reinforced PCC pavement prototypes under early-age loading and harsh environmental conditions.

A Neural Network Based Fault Detection/Management Scheme for Reliable Image Processing Applications
Creators: name: Biasielli, Matteo
Publisher: name: University of Illinois at Chicago
Year: 2019
Subjects: Uncategorized

description: Traditional reliability approaches introduce relevant costs to achieve unconditional correctness during data processing. However, many application environments are inherently tolerant to a certain degree of inexactness or inaccuracy. In this paper, we focus on the practical scenario of image processing in space, a domain where faults are a threat, while the applications are inherently tolerant to a certain degree of errors. We first introduce the concept of usability of the processed image to relax the traditional requirement of unconditional correctness, and to limit the computational overheads related to reliability. We then introduce our new flexible and lightweight fault management methodology for inaccurate application environments. A key novelty of our scheme is the utilization of neural networks to reduce the costs associated with the occurrence and the detection of faults. Experiments on two aerospace image processing case studies show overall time savings of 17.86% and 34.68% for the two applications, respectively, as compared with the baseline classical DWC scheme.

description: Recent progress in the field of topological states of matter(1,2) has largely been initiated by the discovery of bismuth and antimony chalcogenide bulk topological insulators (TIs)(3-6), followed by closely related ternary compounds(7-16) and predictions of several weak TIs(17-19). However, both the conceptual richness of Z$_2$ classification of TIs as well as their structural and compositional diversity are far from being fully exploited. Here, a new Z$_2$ topological insulator is theoretically predicted and experimentally confirmed in the $β$-phase of quasi-one-dimensional bismuth iodide Bi$_4$I$_4$. The electronic structure of $β$-Bi$_4$I$_4$, characterized by Z$_2$ invariants (1;110), is in proximity of both the weak TI phase (0;001) and the trivial insulator phase (0;000). Our angle-resolved photoemission spectroscopy measurements on the (001) surface reveal a highly anisotropic band-crossing feature located at the point of the surface Brillouin zone and showing no dispersion with the photon energy, thus being fully consistent with the theoretical prediction.
The Role of Estradiol in the Modulation of Estrogen Chemical Carcinogenesis by Isoflavones

Publisher: name: University of Illinois at Chicago
Year: 2019

description: Since the Women’s Health Initiative reported that hormone therapy correlated with increased risk of breast cancer, many women have turned to botanical dietary supplements to reduce menopausal symptoms. For example, soy bean (SBE) and red clover (RCE) extracts and their contained isoflavones are consumed by many women for the alleviation of hot flashes. Little is known about isoflavones’ potential ability to affect estrogen chemical carcinogenesis, and whether the presence of estradiol/estrone (E2/E1) in breast tissue influences this modulation. The estrogenic genotoxic pathway involves 4-hydroxylation of E2/E1 by P450 1B1, whereas the detoxification pathway involves 2-hydroxylation by P450 1A1. Both pathways are classically regulated by the aryl hydrocarbon receptor (AhR), and the detoxification pathway is epigenetically downregulated by estrogen receptor alpha (ERalpha). Isoflavone containing extracts were analyzed in a breast cancer cell model (MCF-7) with high, low (1 nM, 1 pM) and no E2 pretreatment and compared to their respective controls. A novel spheroid EROD assay developed for this investigation was applied in conjunction with computational modeling to evaluate extracts/compounds’ activity. 3D-EROD measured the activity of P450 1A/1B1, qPCR determined CYP1A1/1B1 gene expression, and a LC-MS/MS assay measured downstream estrogen metabolites. With no E2 present, RCE, containing both ERalpha and AhR agonists, preferentially increased the genotoxic P450 1B1 pathway. The estrogenic constituents genistein (GN) and daidzein (DZ) and the primarily estrogenic SBE selectively decreased P450 1A activity relative to the negative control. However, in the presence of 1 nM E2 and, to a lesser extent, 1 pM E2, the selective decrease in P450 1A activity reverses. An LC-MS/MS assay indicated that with 1 microM pre- and cotreatment, off target effects of the phytoestrogens, such as the COMT downregulation by GN, are observed. These data indicate that the phytoestrogens likely do not have an adverse effect on the detoxification pathway of estrogens in women, as pre-and postmenopausal breast tissue contains E2/E1. These results emphasize the importance of investigating the effects of botanical dietary supplements and their compounds in different model systems to better understand their efficacy and safety.

Machine-based Statistical Learning of Urban Metabolism
Creators: name: Dongwoo Lee
Publisher: name: University of Illinois at Chicago
Year: 2019
Subjects: Uncategorized

description: This dissertation aims to gain a fundamental understanding of how machine-based statistical learning (ML) can contribute and be applied to the realm of urban metabolism. Along with substantial computational advances, a deluge of ML algorithms has been successfully applied to many domains—although most applications at the time of this writing have focused on the processing of images and sounds. In the realm of urban planning and urban engineering, ML approaches have often been viewed as “mystical.” As acknowledged by many, the use of ML has received some reluctance in domains such as transportation due to their current limitations, often related to poor or lack of interpretability. In this sense, this dissertation fills knowledge gaps in the application of ML. In particular, the efforts are put into addressing interpretability (i.e., explainability), incorporating domain knowledge, and handling uncertainty to better capture patterns in resources use and human behaviors, providing more realistic conclusions in decision-making systems for urban metabolism. Furthermore, this dissertation also contributes to various domains in urban energy and resources consumption studies as these fields have not been exposed extensively to the realm of ML at the time of this writing.

Imposing LHC constraints on the combined Anomaly and $Z^\prime$ Mediation Mechanism of Supersymmetry Breaking
Creators: name: Roy, Joydeep
Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Combining anomaly with $Z^\prime$ mediation allows us to solve the tachyonic problem of the former and avoid fine tuning in the latter. This model includes an extra $U(1)^\prime$ gauge symmetry and extra singlet scalar $S$ which provides a solution to the `$μ$ problem' of the Minimal Supersymmetric Standard Model (MSSM). The low-energy particle spectrum is calculated from the UV inputs using the Renormalization Group Equations. The benchmark points considered in the original model, suggested before the Higgs discovery, predicted a Higgs mass heavier than the generic MSSM value. In 2012, the Higgs particle was discovered and found to have a mass of 125 GeV. Therefore, we can use that value and other current LHC data to scan the parameter space and update the predictions of the model, in particular the mass of the $Z^\prime$ gauge boson.

Preliminary Conceptual Design of 1.6 K Magnetic Refrigerator for CERN Future Circular Collider
Creators: name: Tkaczuk, Jakub
Publisher: name: Zenodo
Year: 2015
Subjects: magnetic refrigeration, Future Cirucla Collider, cryogenics

description: The main goal of this work was to perform a preliminary design of the regenerative magnetic refrigerator for application in the Future Circular Collider, the next-generation particle accelerator designed in CERN. The refrigerator is supposed to cool the superconducting, radio-frequency cavities to accelerate the particles. The design is considered an alternative to the series of cold compressors with a complicated control strategy. The refrigerator's cold end temperature is set at 1.6 K, which is one of the most important objectives of this work from the point of view of its application. The warm end temperature, 4.2 K is a result from using a liquid helium-4 bath at atmospheric pressure. Helium-3 is the medium transferring the heat inside the refrigerator. Despite its high price, this gas was chosen because of its properties - no superfluidity in the working range and the design parameters - no valves in the system. The refrigeration is based on the magneto-caloric effect - material's temperature change with the change of the external magnetic field. Gadolinium Gallium Garnet is the active, magneto-caloric material as it is characterized by a significant entropy change in the working temperature range. The significant difference between this application and previous magnetic refrigerator studies is its large cooling power (up to 1 kW). Such a considerable power implies large dimensions of the refrigerator. This work is the first to consider using the magneto-caloric effect for large cooling capacity. Hence, different phenomena and parameters are essential compared to small-power magnetic refrigerators. The work includes a review of the state of the art, magneto-caloric core geometry selection, calculations of magneto-caloric material and cooling medium properties; and 1D thermodynamic model calculations. The refrigerator's overall design was performed, including a preliminary design of heat exchanges, superconducting coils and displacer. Finally, the parametric study and optimization were done, which resulted in 200 W cooling power at 1.6 K with 1000 kg of Gadolinium Gallium Garnet.

description: Relative biological effectiveness (RBE) plays an important role in designing a uniform dose response for ion beam therapy. In this study the biological effectiveness of a carbon ion beam delivery system was investigated using Monte Carlo simulation. A carbon ion beam delivery line was designed for the Korea Heavy Ion Medical Accelerator (KHIMA) project. The GEANT4 simulation tool kit was used to simulate carbon beam transporting into media. An incident energy carbon ion beam in the range between 220 MeV/u and 290 MeV/u was chosen to generate secondary particles. The microdosimetric-kinetic (MK) model is applied to describe the RBE of 10% survival in human salivary gland (HSG) cells. The RBE weighted dose was estimated as a function of the penetrating depth of the water phantom along the incident beam direction. A biologically photon-equivalent Spread Out Bragg Peak (SOBP) was designed using the RBE weighted absorbed dose. Finally, the RBE of mixed beams was predicted as a function of the water phantom depth.
Translation System Engineering

description: Ribosomal engineering may help elucidate unexplored synthetic potential of the ribosome by manipulation of the peptidyl-transferase center (PTC). However, mutations of many functionally important nucleotides in the PTC are either lethal or highly deleterious for the cell. Therefore, the designed ribosome needs to be functionally isolated from the cellular translation machinery. One solution to this problem is an orthogonal translation system, where both small and large subunits are excluded from the production of cellular proteins and are only engaged in translation of specific mRNAs. The conceptual solution has been achieved recently by engineering of Ribo-T, the ribosome with tethered subunits. Many details of its functionality and assembly remain unknown which precluded further development of the Ribo-T-based orthogonal translation systems. For the first part of this work, we examined the details of the Ribo-T assembly and functionality. It became clear that the covalent linkage between the Ribo-T subunits impedes its assembly and functionality, restricting the bioengineering capacity of such ribosomes. We also attempted to bypass these limitations by developing the principally new design of a specialized translational system. This is achieved by engineering host cells in which Ribo-T carries out translation of cellular proteins, while dissociable ribosome functions as an orthogonal specialized translation machine. Based on this system, a comprehensive library of mutants carrying alterations at every nucleotide of the PTC was generated and it was used to identify the previously unknown aspects of the ribosome’s ability to respond to specific nascent peptide sequences and small molecular weight cofactors. We also used ribosome engineering as a tool for addressing fundamental question why 5S rRNA has been preserved in the course of evolution as a self-standing molecule. By incorporating circularly permutated 5S into 23S rRNAs we engineered a ribosome lacking free 5S rRNA. We showed that the engineered ribosome displays high translational activity while the assembly of the large ribosomal subunit is disrupted. Our results indicate that the evolutionary conservation of 5S rRNA as an independent molecule has been guided primarily by its role in the ribosome assembly, rather than dictated by functional requirements during protein synthesis.

The Effects of Permanent and Temporary Foreign Aid on Fiscal Decisions: Evidence from Sub-Saharan Africa

Publisher: name: University of Illinois at Chicago
Year: 2019
Subjects: Uncategorized

description: Foreign aid is mostly managed by recipient governments, and their decisions on the fiscal management of aid provide insights into how it affects the macroeconomic performance. This dissertation argues that whether aid receipts are permanent or temporary is an important yet overlooked determinant of the fiscal responses to aid. I present a theoretical framework that shows that permanent and temporary aid differently affect the recipient governments' choice between taxes and debt issuance. Empirically, I focus on foreign grants received by sub-Saharan Africa over the period 1990 - 2016, and I separately identify the fiscal responses to permanent and temporary foreign grants. Results suggest that failing to distinguish between permanent and temporary grant receipts results in misleading estimates of the fiscal responses. Results provide guidelines for designing foreign aid programs.

We calculate the Polyakov loop in a wide temperature range, obtain the free energy and the entropy of a single static quark and discuss the QCD crossover region in detail. We show that the entropy has a peak close to the chiral crossover and consider the consequences for the deconfinement aspects of the crossover phenomena. We study the renormalized Polyakov loop susceptibilities and place them into the context of the crossover. We also obtain a quantitative result for the onset of weak coupling behavior at high temperatures.

description: Binary bismuth chalcogenides Bi$_2$Se$_3$, Bi$_2$Te$_3$, and related materials are currently being extensively investigated as the reference topological insulators (TIs) due to their simple surface-state band dispersion (single Dirac cone) and relatively large bulk band gaps. Nanostructures of TIs are of particular interest as an increased surface-to-volume ratio enhances the contribution of surfaces states, meaning they are promising candidates for potential device applications. So far, the vast majority of research efforts have focused on the low-energy (0001) surfaces, which correspond to natural cleavage planes in these layered materials. However, the surfaces of low-dimensional nanostructures (nanoplatelets, nanowires, nanoribbons) inevitably involve higher-index facets. We perform a systematic ab initio investigation of the surfaces of bismuth chalcogenide TI nanostructures characterized by different crystallographic orientations, atomic structures and stoichiometric compositions. We find several stable terminations of high-index surfaces, which can be realized at different values of the chemical potential of one of constituent elements. For the uniquely defined stoichiometric termination, the topological Dirac fermion states are shown to be strongly anisotropic with a clear dependence of Fermi velocities and spin polarization on the surface orientation. Self-doping effects and the presence of topologically trivial mid-gap states are found to characterize the non-stoichiometric surfaces. The results of our study pave the way towards experimental control of topologically protected surface states in bismuth chalcogenide nanostructures.
Mobility, Cosmopolitanism, and the Productions of Place in Kathmandu: A Spatial Ethnography of Thamel
Creators: name: Linder, Benjamin
Publisher: name: University of Illinois at Chicago
Year: 2019
Subjects: Uncategorized

description: This dissertation explores the process through which transnationalism, cultural transformation, and urban space are mutually constituted in the Global South—specifically, in the neighborhood of Thamel in Kathmandu, Nepal. Thamel offers an ideal site to theorize the nexus that links place and subjectivity within a context of accelerating global mobilities. For diversely situated Nepalis, the neighborhood is a zone of ambivalent exception, where a variety of transgressive practices are sanctioned, enacted, and contested. First, this ethnography theorizes the creative practices through which Nepalis construct new cosmopolitanisms as a means of contesting global marginality and normative social roles. Second, it documents the reasons that these cultural shifts instantiated specifically in Thamel, and how the space itself reproduces these transformations. Finally, this project highlights the agency of Nepalis as they increasingly circulate across transnational diasporic networks, thereby (re)producing the socio-spatial changes taking place in Thamel. Since 1990, sharp increases in foreign media consumption, economic opportunity, and transnational mobility have drastically transformed Kathmandu. The practices that are sanctioned in Thamel—e.g., alcohol consumption, women’s use of public space, beef eating—fundamentally challenge notions of “traditional” Nepalipan (“Nepaliness”). This project develops a spatial theory of such cultural changes to understand (1) the way particular places reflect and expand new cultural horizons, and (2) the active role of Nepalis in such transformations. Thamel is a hub through which young Nepalis spatialize transnational mobilities, and it is a space that actively (re)produces emergent transformations in the subjective, cultural, and urban landscapes of contemporary Kathmandu. Part I details the histories, discourses, and cultural politics surrounding the meaning of Thamel. Part II ethnographically explores the spatial production of various cosmopolitanisms. Finally, Part III considers Thamel’s shifting linkages to other sites, both within Kathmandu and across the transnational Nepali diaspora.

description: A binary mixture of super-paramagnetic colloidal particles is confined between glass plates such that the large particles become fixed and provide a two-dimensional disordered matrix for the still mobile small particles, which form a fluid. By varying fluid and matrix area fractions and tuning the interactions between the super-paramagnetic particles via an external magnetic field, different regions of the state diagram are explored. The mobile particles exhibit delocalized dynamics at small matrix area fractions and localised motion at high matrix area fractions, and the localization transition is rounded by the soft interactions [T. O. E. Skinner et al, Phys. Rev. Lett. {\bf 111}, 128301 (2013)]. Expanding on previous work, we find the dynamics of the tracers to be strongly heterogeneous and show that molecular dynamics simulations of an ideal gas confined in a fixed matrix exhibit similar behavior. The simulations show how these soft interactions make the dynamics more heterogenous compared to the disordered Lorentz gas and lead to strong non-Gaussian fluctuations.

description: Accurately quantifying sediment transport rates in rivers remains an important goal for geomorphologists, hydraulic engineers, and environmental scientists. However, current techniques for measuring transport rates are laborious, and formulae to predict transport are notoriously inaccurate. Here, we attempt to estimate sediment transport rates using luminescence, a property of common sedimentary minerals that is used by the geoscience community for geochronology. This method is advantageous because of the ease of measurement on ubiquitous quartz and feldspar sand. We develop a model based on conservation of energy and sediment mass to explain the patterns of luminescence in river channel sediment from a first-principles perspective. We show that the model can accurately reproduce the luminescence observed in previously published field measurements from two rivers with very different sediment transport styles. The parameters from the model can then be used to estimate the time-averaged virtual velocity, characteristic transport lengthscales, storage timescales, and floodplain exchange rates of fine sand-sized sediment in a fluvial system. The values obtained from the luminescence method appear to fall within expected ranges based on published compilations. However, caution is warranted when applying the model as the complex nature of sediment transport can sometimes invalidate underlying simplifications.

description: Background Shift work may be a barrier to healthy eating behaviors among workers. However, the evidence is mainly built on comparisons of eating behaviors between shift workers and non-shift workers. Under what conditions shift work increases the likelihood of unhealthy eating behaviors is still unknown. Growing research also suggests daily experiences and exposures may contribute to fluctuations in people’s daily eating behaviors. Purpose Addressing the research gaps, the goals of this dissertation were to examine the within-person associations between shift work and empty calorie food/beverage consumption and to test whether these associations were exacerbated by daily poor sleep quality or shorter sleep duration. Methods This was a 14-day intensive longitudinal study using ecological momentary assessment. A convenience sample of 80 hospital registered nurses in Taiwan participated. A 21-item food checklist assessed participants’ empty food/beverage consumption. Three dimensions of shift work (i.e., shift timing, shift intensity, and shift speed) were derived from the registry-based work schedule. Daily sleep quality and duration were assessed with the Core Consensus Sleep Diary and Actigraph GT3X, respectively. Three-level mixed-effects regression models were employed for hypothesis testing. Results Participants on night shifts compared to day shifts had greater empty calorie food/beverage consumption. Greater night shift intensity was positively associated with the increased likelihood of sweetened beverage intake. Higher levels of shift speed exacerbated positive associations between (a) shift timing and (b) work shift intensity with sweetened beverage consumption. On days with poor sleep quality, the association between working night shift and fried food/fast food intake was stronger. Relative to slow shift speed workers, poor sleep quality was positively associated with medium/rapid shift speed workers’ likelihood of fried food/fast food consumption. Conclusions Night shift work is associated with increased empty calorie food/beverage consumption among workers. Poor sleep quality exacerbated the adverse effects of shift work on fried food/fast food consumption. Therefore, strategies to promote less hazardous shift work assignments and improve shift workers’ sleep hygiene may help to reduce their empty calorie food/beverage consumption and ultimately their health.

description: This page describes the creation of the stimulus videos and the accuracy criteria that were used to test the state and trait accuracy model. Situations of moderate strength were created so that affect would be the result of an interaction between the situations and personality, which would make it possible for judgments about affect to be informative about judgments of personality.

description: We show that disruption of charge-density-wave (stripe) order by charge transfer excitation, enhances the superconducting phase rigidity in La_{1.885}Ba_{0.115}CuO_4 (LBCO). Time-Resolved Resonant Soft X-Ray Diffraction demonstrates that charge order melting is prompt following near-infrared photoexcitation whereas the crystal structure remains intact for moderate fluences. THz time-domain spectroscopy reveals that, for the first 2 ps following photoexcitation, a new Josephson Plasma Resonance edge, at higher frequency with respect to the equilibrium edge, is induced indicating enhanced superconducting interlayer coupling. The fluence dependence of the charge-order melting and the enhanced superconducting interlayer coupling are correlated with a saturation limit of about 0.5 mJ/cm2. Using a combination of x-ray and optical spectroscopies we establish a hierarchy of timescales between enhanced superconductivity, melting of charge order and rearrangement of the crystal structure.

Hybrid Multi-Sensor Fusion Framework for Perception in Autonomous Vehicles

description: There are many sensor fusion frameworks proposed in the literature using different sensors and fusion methods combinations and configurations. More focus has been on improving accuracy performance; however, the implementation feasibility of these frameworks in an autonomous vehicle is less explored. Some fusion architectures can perform very well in lab conditions using powerful computational resources; however, in real-world applications, they cannot be implemented in an embedded edge computer due to their high cost and computational need. We propose a new hybrid multi-sensor fusion pipeline configuration that performs environment perception for autonomous vehicles such as road segmentation, obstacle detection, and tracking. This fusion framework uses a proposed encoder decoder based Fully Convolutional Neural Network (FCNx) and a traditional Extended Kalman Filter (EKF) nonlinear state estimator method. It also uses a configuration of a camera, lidar, and radar sensors that are best suited for each fusion method. The goal of this hybrid framework is to provide a cost effective, lightweight, modular, and robust (in case of a sensor failure) fusion system solution. It uses the FCNx algorithm that improves road detection accuracy compared to benchmark models while maintaining real-time efficiency that can be used in an autonomous vehicle embedded computer. This algorithm was tested on over 3K road scenes, and our fusion algorithm shows better performance in various environment scenarios compared to baseline benchmark networks. Moreover, the algorithm is implemented in a vehicle and tested using actual sensor data collected from a vehicle, performing real-time environment perception.

description: Techniques for producing cold and ultracold molecules are enabling the study of chemical reactions and scattering at the quantum scattering limit, with only a few partial waves contributing to the incident channel, leading to the observation and even full control of state-to-state collisions in this regime. A new R-matrix formalism is presented for tackling problems involving low- and ultra-low energy collisions. This general formalism is particularly appropriate for slow collisions occurring on potential energy surfaces with deep wells. The many resonance states make such systems hard to treat theoretically but offer the best prospects for novel physics: resonances are already being widely used to control diatomic systems and should provide the route to steering ultracold reactions. Our R-matrix-based formalism builds on the progress made in variational calculations of molecular spectra by using these methods to provide wavefunctions for the whole system at short internuclear distances, (a regime known as the inner region). These wavefunctions are used to construct collision energy-dependent R-matrices which can then be propagated to give cross sections at each collision energy. The method is formulated for ultracold collision systems with differing numbers of atoms.

description: Supervisors, who are in the middle-level positions in organizations, cognitively process and interpret the behaviors of their managers (who are in charge of supervisors). Drawing from motivated information processing theory, this dissertation proposes a dual-process model to explore conditions under which managers’ servant leadership behaviors promote supervisors’ self-interested behavior and team-oriented behavior through two cognitive mechanisms, psychological entitlement and perspective taking. When supervisors have high self-concern, managers’ servant leadership enacts supervisors’ psychological entitlement, which leads to more self-interested behavior and less team-oriented behavior. When supervisors have high other-orientation, managers’ servant leadership triggers supervisors’ perspective taking, which makes supervisors engage in less self-interested behavior and more team-oriented behavior. Using a field study with 76 supervisors and 508 followers, the results demonstrated a negative interactive effect between managers’ servant leadership and supervisors’ other-orientation on supervisors’ perspective taking. Results from the supplementary analysis further indicated a significant moderating effect of supervisors’ self-concern on the relationship between supervisors’ psychological entitlement and self-interested (team-oriented) behavior.

description: We study gender representation on the editorial boards of 435 journals in the mathematical sciences. Women are known to comprise approximately 15% of tenure-stream faculty positions in doctoral-granting mathematical sciences departments in the United States. Compared to this pool, the likely source of journal editorships, we find that 8.9% of the 13067 editorships in our study are held by women. We describe group variations within the editorships by identifying specific journals, subfields, publishers, and countries that significantly exceed or fall short of this average. To enable our study, we develop a semi-automated method for inferring gender that has an estimated accuracy of 97.5%. Our findings provide the first measure of gender distribution on editorial boards in the mathematical sciences, offer insights that suggest future studies in the mathematical sciences, and introduce new methods that enable large-scale studies of gender distribution in other fields.
