description: One objective of this study was to determine the extent of highway safety and geometric problems associated with larger trucks using Kentucky's highways. The accident analysis involved both a general analysis of all truck accidents statewide as well as the identification of specific high-accident locations. A second objective was to identify criteria which can be used in identifying roadway sections that cannot safely accommodate large trucks.  The accident analysis given can be used to investigate locations which have a high number of truck accidents. The general accident statistics related to trucks can be used in the investigation of the high-accident locations to identify factors which may be contributing to the accident problem.  The summary of information obtained from the review of literature can be used as a guide when determining the appropriate criteria to use in formalizing truck access criteria. For example, several references gave recommendations concerning lane width and horizontal curvature appropriate for highways that allowed large truck traffic.

description: We present a pilot program using IRAM's NOrthern Extended Millimeter Array (NOEMA) to probe the molecular gas reservoirs of six $z=0.6-1.1$ star-forming galaxies whose circumgalactic medium has been observed in absorption along quasar lines-of-sight as part of the MusE GAs FLOw and Wind (MEGAFLOW) survey and for which we have estimates of either the accretion or the outflow rate. This program is motivated by testing the quasi equilibrium model and the compaction scenario describing the evolution of galaxies along the main sequence of star formation, which imply tight relations between the gas content, the star formation activity, and the amount of gas flowing in and out. We report individual carbon monoxide CO(4-3), CO(3-2) and dust continuum upper limits, as well as stacked CO detections over the whole sample and the three galaxies identified with outflows. The resulting molecular gas fractions and depletion times are compatible with published scaling relations established within a mass-selected sample, indicating that galaxies selected through their absorption follow similar relations on average. We further detect the dust continuum of three of the quasars and a strong emission line in one of them, which we identify as CO(4-3). Extending the sample to more galaxies and deeper observations will enable to quantify how the molecular gas fraction and depletion time depend on the inflow and ouflow rates.

description: Collective motion of dislocations is governed by the obstacles they encounter. In pure crystals, dislocations form complex structures as they become jammed by their anisotropic shear stress fields. On the other hand, introducing disorder to the crystal causes dislocations to pin to these impeding elements and, thus, leads to a competition between dislocation-dislocation and dislocation-disorder interactions. Previous studies have shown that, depending on the dominating interaction, the mechanical response and the way the crystal yields change. Here we employ three-dimensional discrete dislocation dynamics simulations with varying density of fully coherent precipitates to study this phase transition $-$ from jamming to pinning $-$ using unsupervised machine learning. By constructing descriptors characterizing the evolving dislocation configurations during constant loading, a confusion algorithm is shown to be able to distinguish the systems into two separate phases. These phases agree well with the observed changes in the relaxation rate during the loading. Our results also give insights on the structure of the dislocation networks in the two phases.

description: The objective of this project was to evaluate the performance of Stamark Brand Bisymmetric 1.75 Grade pavement Marking Tape (Series 320) on a large-scale installation on Interstate 24 in McCracken County. The evaluation consisted of periodic inspection of the tape to determine its durability, appearance, and reflectivity.  The tape has demonstrated good performance after two years in service. No durability problems were noted. While the appearance of the tape was not as bright as a typical traffic paint, it was adequate. The tape has maintained a high level of reflectivity. The performance of the material would potentially warrant additional use as longitudinal marking on moderate volume roadways. However, the cost of the tape must be considered in determining its use.

description: The dispersion of viral droplets plays a key role in the transmission of COVID-19. In this work, we analyze the dispersion of cough-generated droplets in the wake of a walking person for different space sizes. The air flow is simulated by solving the Reynolds-Averaged Navier-Stokes equations, and the droplets are modelled as passive Lagrangian particles. Simulation results show that the cloud of droplets locates around and below the waist height of the manikin after two seconds from coughing, which indicates that kids walking behind an infectious patient are exposed to higher transmission risk than adults. More importantly, two distinct droplet dispersion modes occupying significantly different contamination regions are discovered. A slight change of space size is found being able to trigger the transition of dispersion modes even though the flow patterns are still similar. This shows the importance of accurately simulating the air flow in predicting the dispersion of viral droplets and implies the necessity to set different safe-distancing guidelines for different environments.

description: This report includes an analysis of traffic accident data in Kentucky for the years of 1986-1990. A primary objective of this study was to determine average accident statistics for Kentucky highways. Average and critical number and rates of accidents were calculated for various types of highways in rural and urban areas. These data can be used in Kentucky's procedure to identify locations that have abnormal rates or numbers of accidents.  Another objective of this study was to provide data which can be used in the preparation of the problem identification portion of Kentucky's Annual Highway Safety Plan. County and city accident statistics were analyzed. A summary of results and recommendations in several problem identification areas is presented. These general areas include alcohol, occupant protection, speed, pedestrians, bicycles, motorcycles, and vehicle defects. Other areas included in the analysis included drugs, school bus accidents, and truck accidents.

description: The primary objective of this study was to conduct a statewide survey to determine public opinion of a statewide mandatory safety belt law. The survey was conducted so that opinions could be analyzed by areas of the state. The method used to separate the state into geographic regions was to use the boundaries of the 15 Area Development Districts (ADD). A mail survey was conducted with 1,000 questionnaires sent to each ADD. A response rate of 51 percent was obtained.  The respondents were in favor of a statewide law requiring use of safety belts. The statewide percentage in favor of such a law was 76 percent. All regions of the state supported such a law. The percentage in favor ranged from 65 percent in the Lake Cumberland, Gateway, and Buffalo Trace ADDs to 81 percent in the KIPDA ADD.

description: Autonomous agents such as self-driving cars or parcel robots need to recognize and avoid possible collisions with obstacles in order to move successfully in their environment. Humans, however, have learned to predict movements intuitively and to avoid obstacles in a forward-looking way. The task of collision avoidance can be divided into a global and a local level. Regarding the global level, we propose an approach called "Predictive Collision Management Path Planning" (PCMP). At the local level, solutions for collision avoidance are used that prevent an inevitable collision. Therefore, the aim of PCMP is to avoid unnecessary local collision scenarios using predictive collision management. PCMP is a graph-based algorithm with a focus on the time dimension consisting of three parts: (1) movement prediction, (2) integration of movement prediction into a time-dependent graph, and (3) time and risk-dependent path planning. The algorithm combines the search for a shortest path with the question: is the detour worth avoiding a possible collision scenario? We evaluate the evasion behavior in different simulation scenarios and the results show that a risk-sensitive agent can avoid 47.3% of the collision scenarios while making a detour of 1.3%. A risk-averse agent avoids up to 97.3% of the collision scenarios with a detour of 39.1%. Thus, an agent's evasive behavior can be controlled actively and risk-dependent using PCMP.

Collocation spectral methods in the solution of poisson equation
Creators: name: Su, Yuhong
Publisher: name: University of British Columbia
Year: 2009

description: The Poisson equation is a very important partial differential equation for many branches of science and engineering. A fast, robust and accurate Poisson equation solver can find immediate applications in many fields such as electrical engineering, plasma physics, incompressible fluid mechanics and space science. In this thesis, the collocation pseudospectral method is employed to solve Poisson equation. Many papers propose how to apply spectral methods to solve partial differential equations in Cartesian coordinates, but not much attention has been paid to the use of spectral methods in polar coordinates and cylindrical coordinates. In this thesis, the application of the collocation spectral methods to the solution of one and two-dimensional Poisson equations on a rectangular domain in Cartesian coordinates; and on a disk, a part of disk and an annulus in polar coordinates. Also considered is the three-dimensional Poisson equation in a cube in Cartesian coordinates; and a cylinder, a cylindrical annulus and part of a cylinder in cylindrical coordinates. Two of the most important approaches in this thesis are: First we put forward a new collocation spectral method that can avoid the coordinate singularities and solve the Poisson equation in a disk directly by the eigenvalue technique. This can simplify the use of the spectral method in polar coordinates and cylindrical coordinates, where coordinate singularities cause problems for spectral methods. Second, we also give an algorithm that can directly solve the discrete Poisson equation in cylindrical coordinates after discretization by the collocation spectral method. Basically, the idea is that we combine r and z directions together and transform the equation into a form that can be solved by an eigenvalue technique. This method is very fast and efficient.

description: This paper is devoted to the investigation of the energy-momentum problem in two theories, i.e., General Relativity and teleparallel gravity. We use Einstein, Landau-Lifshitz, Bergmann-Thomson and Möller's prescriptions to evaluate energy-momentum distribution of Bell-Szekeres metric in both the theories. It is shown that these prescriptions give the same energy-momentum density components in both General Relativity and teleparallel theory. Möller's prescription yields constant energy in both the theories.

description: Accessibility research has grown substantially in the past few decades, yet there has been no literature review of the field. To understand current and historical trends, we created and analyzed a dataset of accessibility papers appearing at CHI and ASSETS since ASSETS' founding in 1994. We qualitatively coded areas of focus and methodological decisions for the past 10 years (2010-2019, N=506 papers), and analyzed paper counts and keywords over the full 26 years (N=836 papers). Our findings highlight areas that have received disproportionate attention and those that are underserved--for example, over 43% of papers in the past 10 years are on accessibility for blind and low vision people. We also capture common study characteristics, such as the roles of disabled and nondisabled participants as well as sample sizes (e.g., a median of 13 for participant groups with disabilities and older adults). We close by critically reflecting on gaps in the literature and offering guidance for future work in the field.

description: Highly frustrated spin systems such as the kagome lattice (KL) are a treasure trove of new quantum states with large entanglements. We thus study the spin-$\frac{1}{2}$ Heisenberg model on a kagome-strip chain (KSC), which is one-dimensional KL, using the density-matrix renormalization group (DMRG) method. Calculating central charge and entanglement spectrum for the KSC, we find a novel gapless spin liquid state with doubly degenerate entanglement spectra in a 1/5 magnetization plateau. We also obtain a gapless low-lying continuum in the dynamic spin structure calculated by dynamical DMRG method. We propose a resonating dimer-monomer liquid state that would meet these features.

description: We extend the validity of Hardy's nonlocality without inequalities proof to cover the case of special one-parameter classes of non-pure statistical operators. These mixed states are obtained by mixing the Hardy states with a completely chaotic noise or with a colored noise and they represent a realistic description of imperfect preparation processes of (pure) Hardy states in nonlocality experiments. Within such a framework we are able to exhibit a precise range of values of the parameter measuring the noise affecting the non-optimal preparation of an arbitrary Hardy state, for which it is still possible to put into evidence genuine nonlocal effects. Equivalently, our work exhibits particular classes of bipartite mixed states whose constituents do not admit any local and deterministic hidden variable model reproducing the quantum mechanical predictions.

description: Development of dry, ultra-conformable and unperceivable temporary tattoo electrodes (TTEs), based on the ink-jet printing of PEDOT:PSS on top of commercially available temporary tattoo paper, has gained increasing attention as a new and promising technology for electrophysiological recordings on skin. In this work we present a TTEs epidermal sensor for real time monitoring of respiration through transthoracic impedance measurements, exploiting a new design based on the application of soft screen printed Ag ink and magnetic interlink, that guarantees a repositionable, long term stable and robust interconnection of TTEs with external docking devices. The efficiency of the TTE and the proposed interconnection strategy under stretching (up to 10%) and over time (up to 96 hours) has been verified on a dedicated experimental setup and on humans, fulfilling the proposed specific application of transthoracic impedance measurements. The proposed approach makes this technology suitable for large-scale production and suitable not only for the specific use case presented, but also for real time monitoring of different bio-electric signals, as demonstrated through specific proof of concept demonstrators.

description: Η παρούσα εργασία αναφέρεται στη σύνθεση και στη μελέτη δύο κατηγοριών συμπλόκων του Cu(II). Η πρώτη κατηγορία αναφέρεται στη σύνθεση και στη φαρμακοχημική μελέτη των συμπλόκων του χαλκού Cu(II) με α,β, κορεσμένα και ακόρεστα θειοφαινικά υποκατεστημένα παράγωγα των καρβοξυλινών οξέων. Η δεύτερη κατηγορία αναφέρεται στη σύνθεση και μελέτη των παραπάνω συμπλόκων με την παρουσία ενός συνεργιστικού ligand του Ν3. Οι υποκαταστάτες που χρησιμοποιήθηκαν ανήκουν στην συνεχώς αυξανόμενη κατηγορία των αντιφλεγμονωδών και αντιοξειδωτικών φαρμάκων. Τα Ligands αυτά είναι το 2-θειφαιν-καρβοξυλικό οξύ, το 2-θειοφαιν-2υλ-ολικό οξύ, το 3-θειφαιν-2-υλ-ακρυλικό οξύ και το 2-φαινυλ-3 θειφαιν-2-υλ-ακρυλικό οξύ. Παράλληλα τα ανιόντα των ψευδαλογόνων, όπως το ανιον του Ν3 είναι κατάλληλα για το σχεδιασμό ξεχωριστών συστημάτων μιας, δυο ή τριών διαστάσεων.Η σπουδαιότητα του Legand οφείλεται στη δυνατότα σύνδεσής του με σιθενή μεταλλικά ιόντα, όπως ο Cu+2. Ολα τα σύμπλοκα χαρακτηρίστηκαν τόσο σε στερεή κατάσταση όσο και σε διάλυμα από χημικής άποψης
description: The present paper refers to the composition and study of two categories of complexes of Cu(II). The first category corresponds to the composition and to the pharmacochomically study of copper Cu (II) complexes with thiophen-2-yl saturated and a,b, unsaturated substituted carboxylic axids. The second category refers to the composition and study of the previous complexes with the presence of cooperative ligand azide N3. The ligands that were used belong in the continuously increasing category of antiinflammatory and antioxidant drugs. These are the thiophene-2-carboxylic acid, 2 (thiophenen-2-yl)acetic acid, 3 (thiophenen-2-yl)-acrylic acied and 2-phenyl-3(thiophenen-2-yl) acrylic acid. At the same time the pheudohalogens, as the union of azide, are suitable for the planning at discrete systems, one, two or three dimensions.The efficiency of this ligand lies in his ability to connect with bivalent metol ious such as Cu2+. All complexes were characterized in solid state and in solution.

description: The goal of this paper is to extend the existence result of measure-valued solution to the Boltzmann equation in elastic interaction, given by Morimoto-Wang-Yang, to the inelastic Boltzmann equation with moderately soft potentials, also as an extensive work of our preceding result in the inelastic Maxwellian molecules case. We prove the existence and uniqueness of measure-valued solution under Grad's angular cutoff assumption, as well as the existence of non-cutoff solution, for both finite and infinite energy initial datum, by a delicate compactness argument. In addition, the moments propagation and energy dissipation properties are justified for the obtained measure-valued solution as well.

description: When atoms are loaded into an optical lattice, the process of gradually turning on the lattice is almost adiabatic. In this paper we investigate how the temperature changes when going from the gapless superfluid phase to the gapped Mott phase along isentropic lines. To do so we calculate the entropy in the single-band Bose-Hubbard model for various densities, interaction strengths and temperatures in one and two dimensions for homogeneous and trapped systems. Our theory is able to reproduce the experimentally observed visibilities and therefore strongly supports that current experiments remain in the quantum regime for all considered lattice depths with low temperatures and minimal heating.

description: We examine a Peierls ground state and its competing metastable state in the one-dimensional quarter-filled Peierls-Hubbard model with the nearest-neighbor repulsive interaction V and the electron-phonon interaction (\propto 1/K with K being the elastic constant). From the mean-field approach, we obtain the phase diagram for the ground state on the plane of parameters V and K. The coexistent state of the spin-density wave and the charge ordering is realized for large V and K. With decreasing K, it exhibits a first-order phase transition to the unconventional Peierls state which is described by the bond-centered charge-density-wave state. In the large region of the Peierls ground state in the phase diagram, there exists the metastable state where the energy takes a local minimum with respect to the lattice distortion. On the basis of the present calculation, we discuss the photoinduced phase observed in the (EDO-TTF)_{2}PF_{6} compound.

Imaginary charge quantum electrodynamics : a running coupling analysis
Creators: name: Ho, Andy C.T.
Publisher: name: University of British Columbia

description: We construct a modified version of the renormalized tree expansion developed by Gallavotti and Nicolo, the loop regularized running covariance (LRC) tree expansion for expressing the connected Green's functions of the imaginary charge QED model in perturbation theory. By integrating out a sequence of slice fields, the LRC scheme generates a flow of effective potentials V⁸. Here we do not demand that the flow of V⁸ be gauge invariant but only that the Ward Identities hold at the end of the flow. From the flow of V⁸, we obtain a flow of the couplings ʎ⁸ of the local parts of Vs. Using a fixed point analysis in a suitable Banach space whose norm captures the asymptotic form of ʎ⁸, we determine the asymptotic behavior of ʎ⁸ satisfying boundary conditions partially fixed by the Ward Identities. At each step of the flow, the slice covariance is transformed by shifting the local quadratic terms of V⁸ to the Gaussian measure. In this way, the corresponding ʎ⁸ is governed by a flow of an effective coupling ζ⁸which is ultra-violet asymptotically free around the origin. The UV asymptotic freedom of ζ⁸ provides the stability of ʎ⁸ so that the asymptotic form of ʎ⁸ can be obtained from a primitive flow corresponding to only a few low order diagrams of the LRC expansion.

description: The notion of topological phases extended to dynamical systems stimulates extensive studies, of which the characterization of non-equilibrium topological invariants is a central issue and usually necessitates the information of quantum dynamics in both the time and spatial dimensions. Here we combine the recently developed concepts of the dynamical classification of topological phases and synthetic dimension, and propose to efficiently characterize photonic topological phases via holographic quench dynamics. A pseudo spin model is constructed with ring resonators in a synthetic lattice formed by frequencies of light, and the quench dynamics is induced by initializing a trivial state which evolves under a topological Hamiltonian. Our key prediction is that the complete topological information of the Hamiltonian is extracted from quench dynamics solely in the time domain, manifesting holographic features of the dynamics. In particular, two fundamental time scales emerge in the quench dynamics, with one mimicking the Bloch momenta of the topological band and the other characterizing the residue time evolution of the state after quench. For this a dynamical bulk-surface correspondence is obtained in time dimension and characterizes the topology of the spin model. This work also shows that the photonic synthetic frequency dimension provides an efficient and powerful way to explore the topological non-equilibrium dynamics.

description: The constructive role of non-Gaussian random fluctuations is studied in the context of the passage over the dichotomously switching potential barrier. Our attention focuses on the interplay of the effects of independent sources of fluctuations: an additive stable noise representing non-equilibrium external random force acting on the system and a fluctuating barrier. In particular, the influence of the structure of stable noises on the mean escape time and on the phenomenon of resonant activation (RA) is investigated. By use of the numerical Monte Carlo method it is documented that the suitable choice of the barrier switching rate and random external fields may produce resonant phenomenon leading to the enhancement of the kinetics and the shortest, most efficient reaction time.
