description: In this paper, we propose a compositional approach to construct opacity-preserving finite abstractions (a.k.a symbolic models) for networks of discrete-time nonlinear control systems. Particularly, we introduce new notions of simulation functions that characterize the distance between control systems while preserving opacity properties across them. Instead of treating large-scale systems in a monolithic manner, we develop a compositional scheme to construct the interconnected finite abstractions together with the overall opacity-preserving simulation functions. For a network of incrementally input-to-state stable control systems and under some small-gain type condition, an algorithm for designing local quantization parameters is presented to orderly build the local symbolic models of subsystems such that the network of symbolic models simulates the original network for an a-priori defined accuracy while preserving its opacity properties.

A time of passing things : an exploration of the decline and disappearance of the devadasi tradition through the medium of historical fiction
Creators: name: Hunter, Lauren
Publisher: name: University of British Columbia
Year: 2009

description: Written in the form of an historical fiction, this thesis explores the multiple influences that were active in the lives of temple dancers in Southern India from 1861 to 1947. It addresses the question of whether or not the devadasis were prostitutes, placing this debate in the context of conflicting colonial, Hindu and reform movement pressures, influences directing the decline and disappearance of the temple dancing tradition. In gathering information about this period, I have drawn from three main sources: colonial literature of the time, modern feminist research, and dance scholarship on the nature and history of the technical aspects of temple dancing. My aim has been to reconstruct, as accurately as possible, a close approximation of a devadasi's life, and to compare how it differs from those lived by previous generations of temple dancers.

description: We propose a mixed analytical-ab-initio method for the accurate calculation of the conductance in monovalent atomic wires. The method relies on the most general formula for ballistic transport through a monovalent wire, whose parameters can be determined from first-principles calculations. Our central result is the demonstration of the highly non-universal behavior of the conductance, which depends on the fine details of the contacts to the leads. We are therefore able to reconcile a large number of the apparently contradictory results that have recently appeared in the literature.

description: The controlled modification of the electronic properties of ZnO nanorods via transition metal doping is reported. A series of ZnO nanorods were synthesized by chemical bath growth with varying Co content from 0 to 20 atomic % in the growth solution. Optoelectronic behavior was probed using cathodoluminescence, time-resolved luminescence, transient absorbance spectroscopy, and the incident photon-to-current conversion efficiency (IPCE). Analysis indicates the crucial role of surface defects in determining the electronic behavior. Significantly, Co-doping extends the light absorption of the nanorods into the visible region, increases the surface defects, shortens the non-radiative lifetimes, while leaving the radiative lifetime constant. Furthermore, for 1 atomic % Co-doping the IPCE of the ZnO nanorods is enhanced. These results demonstrate that doping can controllably tune the functional electronic properties of ZnO nanorods for applications.

description: Speaker Recognition and Speaker Identification are challenging tasks with essential applications such as automation, authentication, and security. Deep learning approaches like SincNet and AM-SincNet presented great results on these tasks. The promising performance took these models to real-world applications that becoming fundamentally end-user driven and mostly mobile. The mobile computation requires applications with reduced storage size, non-processing and memory intensive and efficient energy-consuming. The deep learning approaches, in contrast, usually are energy expensive, demanding storage, processing power, and memory. To address this demand, we propose a portable model called Additive Margin MobileNet1D (AM-MobileNet1D) to Speaker Identification on mobile devices. We evaluated the proposed approach on TIMIT and MIT datasets obtaining equivalent or better performances concerning the baseline methods. Additionally, the proposed model takes only 11.6 megabytes on disk storage against 91.2 from SincNet and AM-SincNet architectures, making the model seven times faster, with eight times fewer parameters.

Center vortex model for the infrared sector of SU(4) Yang-Mills theory: String tensions and deconfinement transition
Creators: name: Engelhardt, Michael

Year: 2005
Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: FOS: Physical sciences

description: A random vortex world-surface model for the infrared sector of SU(4) Yang-Mills theory is constructed, focusing on the confinement properties and the behavior at the deconfinement phase transition. Although the corresponding data from lattice Yang-Mills theory can be reproduced, the model requires a more complex action and considerably more tuning than the SU(2) and SU(3) cases studied previously. Its predictive capabilities are accordingly reduced. This behavior has a definite physical origin, which is elucidated in detail in the present work. As the number of colors is raised in Yang-Mills theory, the corresponding infrared effective vortex description cannot indefinitely continue to rely on dynamics determined purely by vortex world-surface characteristics; additional color structures present on the vortices begin to play a role. As evidenced by the modeling effort reported here, definite signatures of this behavior appear in the case of four colors.

description: The reduction of systematic errors in terrestrial reference frames (TRF) is crucial fornumerous scientific and societal applications. To support this effort, the European SpaceAgency (ESA) plans to launch a dedicated space-geodetic mission, Genesis, in 2028. Forthe first time, VLBI will be required to observe and process satellite data, presenting bothnovel challenges and exciting opportunities.In this work, we present preliminary studies supporting the Genesis mission, with a focuson scheduling and simulations. We investigate key aspects such as network visibility underdifferent orbital parameters, specifically examining the impact of orbit altitude (ranging from4000 to 9000 km) and inclination (ranging from 60 to 95 degrees). Our simulations showthat while orbit altitude significantly affects visibility, lower inclinations allow the satellite tobe observed slightly longer by at least two stations. Conversely, higher inclinations result inlonger visibility with a larger network.Additionally, we outline the current status and roadmap for essential VLBI softwaredevelopments, aiming to foster discussions and potential collaborations within thecommunity.

description: Successful risk management strategies for agribusiness firms are contingent on the ability to accurately forecast basis. There has been substantial research on the actual use of basis forecasts, yet little research has been conducted on actually forecasting basis. This study evaluates the effect incorporating current basis information into a historical-average-based-forecast has on forecasting accuracy when forecasting live cattle and feeder cattle basis. Furthermore, the optimal weight to place on this current information is evaluated in an out-of-sample framework. Root mean squared errors are generated for both commodities and evaluated to determine the significance of these issues. Results suggest that livestock basis forecasters should consider incorporating a proportion of the difference in current basis and the historical average of the current week when making their projections. The optimal amount of current information to include declines as the time interval between the week the forecast is being made and the week being forecasted increases.

Optical model data analyzes were performed with an adjustable factor of normalization included in the imaginary part of the potential. These analyzes indicated a reduction of absorption for systems with small reduced masses that was detected due to the refractive nature of the scattering by light systems.

description: Urban greenery is considered an important factor in relation to sustainable development and people's quality of life in the city. Although ways to measure urban greenery have been proposed, the characteristics of each metric have not been fully established, rendering previous researches vulnerable to changes in greenery metrics. To make estimation more robust, this study aims to (1) propose an improved indicator of greenery visibility for analytical use (standardized GVI; sGVI), and (2) quantify the relation between sGVI and other greenery metrics. Analyzing a data set for Yokohama city, Japan, it is shown that the sGVI, a weighted form of GVI aggregated to an area, mitigates the bias of densely located measurement sites. Also, by comparing sGVI and NDVI at city block level, we found that sGVI captures the presence of vegetation better in the city center, whereas NDVI is better in capturing vegetation in parks and forests. These tools provide a foundation for accessing the effect of vegetation in urban landscapes in a more robust matter, enabling comparison on any arbitrary geographical scale.

description: Motivated by the instability of the Savvidy-Nielsen-Olesen vacuum we make a systematic search for a stable magnetic background in pure SU(2) QCD. It is shown that a pair of axially symmetric monopole and antimonopole strings is stable, provided that the distance between the two strings is less than a critical value. The existence of a stable monopole-antimonopole string background strongly supports that a magnetic condensation of monopole-antimonopole pairs can generate a dynamical symmetry breaking, and thus the magnetic confinement of color in QCD.

description: We investigate the use of image-and-spatial transformer networks (ISTNs) to tackle domain shift in multi-site medical imaging data. Commonly, domain adaptation (DA) is performed with little regard for explainability of the inter-domain transformation and is often conducted at the feature-level in the latent space. We employ ISTNs for DA at the image-level which constrains transformations to explainable appearance and shape changes. As proof-of-concept we demonstrate that ISTNs can be trained adversarially on a classification problem with simulated 2D data. For real-data validation, we construct two 3D brain MRI datasets from the Cam-CAN and UK Biobank studies to investigate domain shift due to acquisition and population differences. We show that age regression and sex classification models trained on ISTN output improve generalization when training on data from one and testing on the other site.

The modulator acts as a phase grating which can generate arbitrary diffraction patterns and be rapidly reconfigured at rates up to 1 kHz to create smooth, time-varying optical potentials. The flexibility of the device is demonstrated with our experimental results for splitting a Bose-Einstein condensate and independently transporting the separate parts of the atomic cloud.

description: Mandatory livestock price reporting has changed how prices are reported and used. Reporting has affected the availability of many reports and has added new reports and information. A variety of research issues are facilitated by the scope of new information available. However, the new information often needs to be put into meaningful form for direct use. A brief overview of the evolution and implementation of mandatory price reporting is given. The new price reports are then discussed and compared to voluntary reports. There is enough new information that analysts may be able to make different insights into price formation. Special attention is given to new reports that give insights into the short-run cattle supply situation. While the focus is on cattle reports, swine reports are also briefly discussed.

It is shown that the Goldstone mode, or helimagnon, is a propagating mode with a highly anisotropic dispersion relation, in analogy to the Goldstone mode in chiral liquid crystals. Starting from a microscopic theory, a comprehensive effective theory is developed that allows for an explicit description of the helically ordered phase, including the helimagnons, for both classical and quantum helimagnets. The directly observable dynamical spin susceptibility, which reflects the properties of the helimagnon, is calculated.

description: The farm level economic impacts of the Farm Security and Rural Investment Act of 2002 on representative crop and livestock operations are projected in this report. The analysis was conducted over the 2005-2012 planning horizon using FLIPSIM, AFPC’s whole farm simulation model. Data to simulate farming operations in the nation’s major production regions came from two sources: • Producer panel cooperation to develop economic information to describe and simulate representative crop, livestock, and dairy farms, and • Projected prices, policy variables, and input inflation rates from the Food and Agricultural Policy Research Institute (FAPRI) August 2007 Baseline. The FLIPSIM policy simulation model incorporates the historical risk faced by farmers for prices and production. This report presents the results of the August 2007 Baseline in a risk context using selected simulated probabilities and ranges for annual net cash farm income values. The probability of a farm experiencing negative ending cash reserves and the probability of a farm losing real net worth are included as indicators of the cash flow and equity risks facing farms through the year 2012.

description: We have investigated charged Higgs boson production via the gluon-bottom quark mode, gb -> tH+, followed by its decay into a chargino and a neutralino. The calculations are based on masses and couplings given by the Minimal Supersymmetric Standard Model (MSSM) for a specific choice of MSSM parameters. The signature of the signal is characterized by three hard leptons, a substantial missing transverse energy due to the decay of the neutralino and the chargino and three hard jets from the hadronic decay of the top quark. The possibility of detecting the signal over the Standard Model (SM) and non-SM backgrounds was studied for a set of tanBeta and mA. The existence of 5-sigma confidence level regions for H+ discovery at integrated luminosities of 100 fb-1 and 300 fb-1 is demonstrated, which cover also the intermediate region 4 < tanBeta < 10 where H+ decays to SM particles cannot be used for H+ discovery.

Expressed as 90% confidence levels (CL), we find $< 0.46 % $ and $ < 0.78%$ respectively. This is the first successful use of genetic programming in a high energy physics data analysis.

description: Entangled ring polymers, along with blends of ring and linear polymers, continue to be a topic of great interest and debate due to the conflicting experimental results in the literature as well as the difficulty of producing entangled synthetic rings devoid of linear contaminants. Here, we create blended solutions of entangled ring and linear DNA with varying mass fractions of linear DNA. We use optical tweezers microrheology to measure the linear and nonlinear viscoelastic response of these blends. Our measurements reveal a strong non-monotonic dependence of linear viscoelastic properties on linear DNA fraction, with a pronounced maximum when the mass fraction of rings and linear chains are comparable, suggestive of pervasive threading of rings by linear chains. We observe a similar non-monotonicity in the nonlinear regime; however, a comparatively higher fraction of linear chains (0.5-0.7) is required for a substantial increase in resisitive force and slowing of relaxation dynamics to emerge. This nonlinear response also appears to be rate dependent, which we argue arises from force-induced de-threading of rings at high strain rates. Our results fill a longstanding gap in knowledge regarding the microrheology and nonlinear response of ring-linear polymer blends. Moreover, the uniquely strong mechanical response that ring-linear blends exhibit, along with the ability to finely tune these blends by varying the blend composition, provides new materials design principles.

description: Durante los últimos 25 años el gasto educativo público real en el Perú se ha mantenido relativamente constante, aunque con fluctuaciones relacionadas con el ciclo económico. Sin embargo, en un contexto de marcado crecimiento de la matrícula, esto ha implicado una caída significativa en el gasto por alumno, en particular, en la educación básica. Como parte de este proceso se observó un aumento del número de docentes y de personal administrativo - en particular a partir de 1985 - con una caída en los ingresos reales de los mismos. El gasto por alumno así como la variabilidad del gasto educativo en el Perú es similar al promedio latinoamericano. Sin embargo, el gasto es menos de un sexto del observado en países de la OECD. El gasto público en educación alcanzó el 2.8% del PBI en 1994. Estimaciones realizadas en base a encuestas de hogares muestran que las familias que matricularon a sus hijos en instituciones educativas públicas aportaron un 0.8%. Si además, se contabiliza el gasto de las familias en instituciones privadas, el gasto total de las familias llega a 1.9%. Así, si bien la educación pública, que en el caso de la educación básica constituye el 85% de la matrícula, es gratuita, las familias peruanas en conjunto gastan en educación -a través de aportaciones extraordinarias, cuotas de padres de familia, y gastos en materiales- 2/3 de lo que gasta el Estado. La sociedad peruana en conjunto gasta al menos 4.7% del PBI en educación. Finalmente, se encuentra que, la distribución del gasto educativo por alumno no es equitativa, siendo éste mayor en aquellos departamentos donde los indicadores de pobreza son menores.

description: Using very general arguments, we prove that any entanglement measures based on distance must be maximal on pure states. Furthermore, we show that Bures measure of entanglement and geometric measure of entanglement satisfy the monogamy inequality on all pure multiqubit states. Finally, using the power of Bures measure of entanglement and geometric measure of entanglement, we present a class of tight monogamy relations for pure states of multiqubit systems.

description: We study unitary random matrix ensembles in the critical case where the limiting mean eigenvalue density vanishes quadratically at an interior point of the support. We establish universality of the limits of the eigenvalue correlation kernel at such a critical point in a double scaling limit. The limiting kernels are constructed out of functions associated with the second Painleve equation. This extends a result of Bleher and Its for the special case of a critical quartic potential. The two main tools we use are equilibrium measures and Riemann-Hilbert problems. In our treatment of equilibrium measures we allow a negative density near the critical point, which enables us to treat all cases simultaneously. The asymptotic analysis of the Riemann-Hilbert problem is done with the Deift/Zhou steepest descent analysis. For the construction of a local parametrix at the critical point we introduce a modification of the approach of Baik, Deift, and Johansson so that we are able to satisfy the required jump properties exactly.

The center-mode instability of viscoelastic plane Poiseuille flow

description: A modal stability analysis shows that plane Poiseuille flow of an Oldroyd-B fluid becomes unstable to a `center mode' with phase speed close to the maximum base-flow velocity, $U_{max}$. The governing dimensionless groups are the Reynolds number $Re = ρU_{max} H/η$, the elasticity number $E = λη/(H^2ρ)$, and the ratio of solvent to solution viscosity $η_s/η$; here, $λ$ is the polymer relaxation time, $H$ is the channel half-width, and $ρ$ is the fluid density. For experimentally relevant values (e.g., $E \sim 0.1$ and $β\sim 0.9$), the predicted critical Reynolds number, $Re_c$, for the center-mode instability is around $200$, with the associated eigenmodes being spread out across the channel. In the asymptotic limit of $E(1 -β) \ll 1$, with $E$ fixed, corresponding to strongly elastic dilute polymer solutions, $Re_c \propto (E(1-β))^{-\frac{3}{2}}$ and the critical wavenumber $k_c \propto (E(1-β))^{-\frac{1}{2}}$. The unstable eigenmode in this limit is confined in a thin layer near the channel centerline. The above features are largely analogous to the center-mode instability in viscoelastic pipe flow (Garg et al., Phys. Rev. Lett., 121, 024502 (2018)), and suggest a universal linear mechanism underlying the onset of turbulence in both channel and pipe flows of suffciently elastic dilute polymer solutions.

description: Global environmental research requires long-term climate data. Yet, meteorological infrastructure is missing in the vast majority of the world’s protected areas. Therefore, gridded products are frequently used as the only available climate data source in peripheral regions. However, associated evaluations are commonly biased towards well observed areas and consequently, station-based datasets. As evaluations on vegetation monitoring abilities are lacking for regions with poor data availability, we analyzed the potential of several state-of-the-art climate datasets (CHIRPS, CRU, ERA5-Land, GPCC-Monitoring-Product, IMERG-GPM, MERRA-2, MODIS-MOD10A1) for assessing NDVI anomalies (MODIS-MOD13Q1) in two particularly suitable remote conservation areas. We calculated anomalies of 156 climate variables and seasonal periods during 2001–2018, correlated these with vegetation anomalies while taking the multiple comparison problem into consideration, and computed their spatial performance to derive suitable parameters. Our results showed that four datasets (MERRA-2, ERA5-Land, MOD10A1, CRU) were suitable for vegetation analysis in both regions, by showing significant correlations controlled at a false discovery rate

title: Manipulating anisotropic transport and superconductivity by focused ion beam microstructuring

Publisher: name: University of St Andrews

description: This thesis presents the results of electrical transport experiments performed on two microstructured quantum materials, namely on the ultra-pure metal PdCoO₂ and on the heavy fermion superconductor CeIrIn₅. Throughout this work, focused ion beam (FIB) microsculpting was utilised to design the investigated devices. I begin with an introduction to the FIB instrument, with a specific focus on its application for microstructuring transport devices from quantum materials. In particular, our standard fabrication procedure, in which a thin slab of material is extracted from a bulk single crystal for further processing is described in detail, as this approach can be utilised for most metallic compounds. Furthermore, I describe a micro-fabrication process for creating transport devices from platelet-shaped single crystals. Thereafter I present ballistic transport measurements of the ultra-pure delafossite metal PdCoO₂. By investigating mesoscopic transport bars which are narrower than the electron mean free path (up to 20 μm), I demonstrate that the ballistic transport in PdCoO₂ is strongly anisotropic as a result of the underlying quasi-hexagonal Fermi surface shape. Moreover, I report on the results of transverse electron focusing (TEF) experiments, a technique which directly probes the real space ballistic trajectories of electrons in a magnetic field, which demonstrate the super-geometric focusing effect. Furthermore, by investigating microstructures of the superconducting heavy fermion compound CeIrIn₅ by means of transport measurements as well as scanning SQUID microscopy in collaboration with external groups, a route to controllably manipulate the local strain in microstructured devices was found. The presented approach is based on exploiting the substrate-induced biaxial strain due to differential thermal contraction, which is spatially tailored by defined FIB cuts. As the superconducting transition in the heavy fermion compound CeIrIn₅ is highly sensitive to strain, the local T[sub]c within the device is controlled via the spatial strain distribution.
The effect of growth factors on bulbospinal neurite outgrowth in an in vitro embryonic chick model
Creators: name: Salie, Rishard
Publisher: name: University of British Columbia

description: Injury to the spinal cord of higher vertebrates damages motor axons that connect the brain and brainstem with their targets in the spinal cord. Axotomized central nervous system (CNS) neurons often experience degeneration of the distal axon, retraction of the proximal end, and atrophy of the cell body. Injured neurons in the CNS do not experience significant functional regeneration, so spinal cord insult often results in permanently compromised locomotor ability. The capability of a severed axon to re-grow is thought to depend on the interplay between intrinsic and external cues. Regenerative failure in the mature axon is thought to be the result of: a) failure to survive primary and secondary damage, b) glial scarring, c) presence of inhibitory growth substrates that prevent neuronal extension, and d) decreased availability of neurotrophic factors and permissive substrates supporting neuronal process extension. Application of trophic factors to axotomized neurons has been shown to enhance survival and neurite outgrowth. Although brainstem-spinal connections play the pivotal role in motor dysfunction, we still know relatively little about the trophic sensitivity of these populations. The experiments presented in this study will help to elucidate the role trophic molecules play in process extension in brainstem-spinal neuron populations. Using an assay specifically developed to examine the effect of trophic molecules on neuronal process extension, this study explores the response of bulbospinal populations to various trophic factors. Already investigated in our laboratory using these techniques are members of the fibroblast growth factor family, (FGF-1,-2, -5 and -9). Several growth factors were initially examined for potential trophic effects on the projection neurons of the brainstem. Nerve growth factor (NGF), glial derived neurotrophic factor (GDNF) and epidermal growth factor (EGF) did not effect process outgrowth in the bulbospinal neurons of the vestibular complex (vestibulospinal neurons). Brain derived neurotrophic factor (BDNF) and insulin-like growth factor (IGF-1) significantly enhance mean process length in both the vestibulospinal neurons and projection neurons from the raphe nuclei (raphespinal neurons). Neurotrophin-3 (NT-3) and neurotrophin-4 (NT-4) require further study to determine their contribution to process elongation. In order to examine the mechanism of trophic factor effects, immunohistochemistry to the cognate receptors for BDNF and IGF-1 was performed. At the developmental stages used in the study, it was determined that receptors for BDNF and IGF-1 were present both on bulbospinal neurons and on surrounding cells with a non-neuronal morphology. It is hoped that this study will contribute to the growing pool of knowledge on spinal cord injury, and may one day play a role in development of a multi-faceted therapy for spinal cord injury.

description: The axino and the gravitino are well-motivated candidates for the lightest supersymmetric particle (LSP) and also for cold dark matter in the Universe. Assuming that a charged slepton is the next-to-lightest supersymmetric particle (NLSP), we show how the NLSP decays can be used to probe the axino LSP scenario in hadronic axion models as well as the gravitino LSP scenario at the Large Hadron Collider and the International Linear Collider. We show how one can identify experimentally the scenario realized in nature. In the case of the axino LSP, the NLSP decays will allow one to estimate the value of the axino mass and the Peccei-Quinn scale.
