description: In the first quarter of 2020, the doors of museums around the world shut and their operations at physical sites were reduced in line with necessary security measures. This heralded the beginning of an uncertain future for museums and galleries as the COVID-19 pandemic hit and the only means to stay ‘open’ was to turn towards the digital. In this paper, we investigate how the physical closure of museum buildings due to lockdown restrictions caused shockwaves within their digital strategies and changed their data practices potentially for good. The methodology of the research involves a review of the impact of COVID-19 on the museum sector, based on literature and desk research, with a focus on the implications for three museums and art galleries in the United Kingdom and the United States, and their mission, objectives, and digital data practices. We also present analysis of ten qualitative interviews with expert witnesses working in the sector, representing different roles and types of institutions, undertaken between April and October 2020. Our research finds that digital engagement with museum content and practices around data in institutions have changed and that digital methods for organising and accessing collections for both staff and the general public have become more important. We present evidence that strategic preparedness influenced how well institutions were able to transition during closure, and that metrics data became pivotal in understanding this novel situation. Increased engagement online changed traditional audience profiles, challenging museums to find ways of accommodating new forms of engagement in order to survive and thrive in the post-pandemic environment. Our findings point to a longer-term shift in the operating models for museums and the need to realise economic value and diversify income streams through digital means, which have not yet been clearly established. The research suggests that the unprecedented situation brought on by the pandemic will shape future museum audiences and their interactions with institutions virtually and physically, posing challenges to museums and their constituents that require structural changes and adaptations, but also present opportunities to successfully survive in an ever-more connected world.

description: The free parameters of a flat accelerating model without dark energy are constrained by using Supernovae type Ia and observational H(z) data. Instead of the vacuum dominance, the present accelerating stage in this modified Einstein-de Sitter cosmology is a consequence of the gravitationally-induced particle production of cold dark matter. The model present a transition from a decelerating to an accelerating regime at low redshifts, and is also able to harmonize a cold dark matter picture with the latest measurements of the Hubble constant H_0, the Supernovae observations (Constitution sample), and the H(z) data.

description: It is estimated that 60% of people who die by suicide experience depression. For young people aged 15 to 34, suicide was the second leading cause of death in 2012. Men have had higher rates of suicide in Canada at every point in time – up to 3 times higher depending on the year - for the past 60 years. This qualitative study explores the experiences of ten male adults between the ages of 18 to 32 with mild-to-moderate symptoms of depression that participated in a single-gender group psychotherapy program called, The Men’s Transition Program (MTP). This study investigated the interventions and processes that were reported as helpful, in what capacity they were, and the perceived impact of these during and after the program. Ten semi-structured in-depth interviews, with questions inspired by the Enhanced Critical Incident Technique, were conducted. Thematic analysis was utilized to examine the reported changes as a result of the processes and interventions implemented in the program. Themes that emerged included: social connection and support, interpersonal learning, positive mood, self-confidence, self-esteem, normalization, improved social functioning, reduction in guilt, higher energy levels, and increased motivation. Implications of these findings will be discussed.

description: A sample of 27 sources, catalogued as pre-main sequence stars by the Pico dos Dias Survey (PDS), is analyzed to investigate a possible contamination by post-AGB stars. The far-infrared excess, due to dust present in the circumstellar envelope, is typical for both categories: young stars and objects that have already left the main sequence and are suffering a severe mass-loss. The presence of two known post-AGB stars in our sample inspired us to seek for other very likely or possible post-AGB objects among PDS sources previously suggested to be Herbig Ae/Be stars, by revisiting the observational database of this sample. In a comparative study with well known post-AGBs, several characteristics were evaluated: (i) parameters related to the circumstellar emission; (ii) spatial distribution to verify the background contribution from dark clouds; (iii) spectral features, and (iv) optical and infrared colors. These characteristics suggest that 7 objects of the studied sample are very likely post-AGBs, 5 are possible post-AGBs, 8 are unlikely post-AGBs, and the nature of 7 objects remains unclear.

description: Many local governments and transit agencies in the United States face financial difficulties in providing adequate public transit service in individual systems, and in providing sufficient regional coordination to accommodate transit trips involving at least one transfer between systems. These difficulties can be attributed to the recent economic downturn, continuing withdrawal of the state and federal funds that help support local transit service, a decline in local funding for transit service in inner cities due to ongoing suburbanization, and a distribution of resources that responds to geographic equity without addressing service needs. This study examines two main research questions: (1) the effect of a “delegated management” contract on efficiency and effectiveness within a single transit system, and (2) the effects of a single private firm—contracted separately by more than one agency in the same region—on regional coordination, exploring the case in Greater New Orleans. The current situation in New Orleans exhibits two unique transit service conditions. First, New Orleans Regional Transit Authority (RTA) executed a “delegated management” contract with a multinational private firm, outsourcing more functions (e.g., management, planning, funding) to the contractor than has been typical in the U.S. Second, as the same contractor has also been contracted by another transit agency in an adjacent jurisdiction—Jefferson Transit (JeT), this firm may potentially have economic incentives to improve regional coordination, in order to increase the productivity and effectiveness of its own transit service provision. Although the limited amount of available operation and financial data has prevented us from drawing more definitive conclusions, the findings of this multifaceted study should provide valuable information on a transit service contracting approach new to the U.S.: delegated management. This study also identified a coherent set of indices with which to evaluate the regional coordination of transit service, the present status of coordination among U.S. transit agencies, and barriers that need to be resolved for regional transit coordination to be successful.

description: This work reports the measurement of magnetic dichroism in angular-resolved photoemission from in-plane magnetized buried thin films. The high bulk sensitivity of hard X-ray photoelectron spectroscopy (HAXPES) in combination with circularly polarized radiation enables the investigation of the magnetic properties of buried layers. HAXPES experiments with an excitation energy of 8 keV were performed on exchange-biased magnetic layers covered by thin oxide films. Two types of structures were investigated with the IrMn exchange-biasing layer either above or below the ferromagnetic layer: one with a CoFe layer on top and another with a Co$_2$FeAl layer buried beneath the IrMn layer. A pronounced magnetic dichroism is found in the Co and Fe $2p$ states of both materials. The localization of the magnetic moments at the Fe site conditioning the peculiar characteristics of the Co$_2$FeAl Heusler compound, predicted to be a half-metallic ferromagnet, is revealed from the magnetic dichroism detected in the Fe $2p$ states.

description: Human motion recognition is an important topic in computer vision as well as security. It is used in scientific research, surveillance cameras industry and robotics technology as well. The human interaction with the objects creates a complex stance. Multiple artefacts such as clutter, occlusions, and backdrop diversity contribute to the complexity of this technology. Wi-Fi signals with the usage of their features could help solve some of these issues, with the help of other wearable sensors, such as: RGB-D camera, IR sensor (thermal camera), inertial sensor etc. This paper reviews various approaches for Wi-Fi human motion recognition systems, their analytical methodologies, challenges and proposed techniques along with the aspects to this paper: (a) applications; (b) single and multi-modality sensing; (c) Wi-Fi-based techniques; d) challenges and future works. More research related to Wi-Fi human related activity recognition can be encouraged and improved.

description: Infrared divergences of QCD scattering amplitudes can be derived from an anomalous dimension matrix, which is also an essential ingredient for the resummation of large logarithms due to soft gluon emissions. We report a recent analytical calculation of the anomalous dimension matrix with both massless and massive partons at two-loop level, which describes the two-loop infrared singularities of any scattering amplitudes with an arbitrary number of massless and massive partons, and also enables soft gluon resummation at next-to-next-to-leading-logarithmic order. As an application, we calculate the infrared poles in the q qbar -> t tbar and gg -> t tbar scattering amplitudes at two-loop order.

We gon’ be alright : Kendrick Lamar’s criticism of racism and the potential for social change through love
Creators: name: Heffernan, Courtney Julia
Publisher: name: University of British Columbia
Year: 2016

description: This thesis explores Kendrick Lamar’s criticism of institutionalized racism in America and its damaging effects on African-American subjectivity on his albums Section.80, Good Kid M.A.A.D City and To Pimp a Butterfly. The albums address the social implications of racism in the present day, throughout Lamar’s life and throughout the lives of his ancestors. In my analysis of Lamar’s albums, I address the history of American chattel slavery and its aftermath as a social system that privileges white over black. On the basis of my interpretation of the penultimate track on To Pimp a Butterfly, “i,” I propose a love ethic as a means through which the American social order can be changed. I take the term love ethic from Cornel West and bell hooks. A love ethic is a means through which individual bodies hurt by racism can be recognized and revalorized. Through the course of his three studio albums Lamar offers a narrative remediation of America’s discriminatory social order. In so doing, Lamar enacts the social change he wishes to see in America.
Instability of the Noncommutative Geometry Inspired Black Hole

description: Non-commutative geometries have been proposed as an approach to quantum gravity and have led to the construction of non-commutative black holes, whose interior singularities are purportedly eliminated due to quantum effects. Here we find evidence that these black holes are in fact unstable, with infalling matter near the Cauchy (inner) horizon being subject to an infinite blueshift of the type that has been repeatedly demonstrated for the Reissner-Nordstr\(\ddot{\text{o}}\)m black hole. This instability is present even when an ultraviolet cutoff (induced by anticipated non-commutative geometric effects) to a field propagating in that spacetime is included. We demonstrate this by following an analogous argument made for Reissner-Nordstr\(\ddot{\text{o}}\)m black holes, and conclude that stability is dependent on the surface gravities \(κ_-\) and \(κ_+\) of the inner and outer horizons respectively. In general if \(κ_- > κ_+\), as we show to be the case here, then the stability of the Cauchy horizon becomes highly questionable, contrary to recent claims.

However, concerns on the stability of the magnetic properties of different DMS systems have been raised. Their magnetic moment is often unstable, vanishing with a characteristic decay time of weeks or months, which precludes the development of real applications.

description: The aim of this work is to study the holographic dual to the gauge theory with a nonzero gluon condensate. We check for consistency the holographic way of describing the condensate and calculate the expectation value of a small Wilson loop in the presence of the gluon condensate, thus obtaining the relevant coefficient in the operator product expansion of the small loop in different holographic models. We also study the effect of the condensate on the Gross-Ooguri phase transition in the correlator of two circular Wilson loops in parallel and concentric configurations. In the numerical study of the concentric case, we find that the phase transition changes its order when the size of the loops is of order of the gluon condensate. We report this change of the phase transition order to be a new effect in Wilson loop correlators.

description: The ATLAS experiment at the Large Hadron Collider is one of the most powerful tools for the measurement of the Standard Model properties and the search for new physics beyond it. This thesis describes a search for such a Beyond the Standard Model theory and also the development of the readout system of the future ATLAS Inner Tracker Pixel detector. Supersymmetric expansions of the Standard Model can solve some of the fundamental problems of it, but no sign of Supersymmetry has been found so far. This work presents the search for a Supersymmetry model that does not adhere to the Minimal Flavour Violation paradigm that is usually followed by simplified Supersymmetry searches. This opens the door to a possible mixing between the second and third generation supersymmetric partners of the quarks, the top-squark (~t) and the charmsquark (~c). In this Supersymmetry realisation, the decay of pair-produced ~t1 can lead to final states with a b-jet, a c-jet and missing transverse momentum coming from the pair of neutralinos (~x01), which are the lightest supersymmetric particles in this model. I performed a search for this tc + EmissT final state using simultaneous b- and c-tagging and also top-tagging techniques. In this context, I developed a Neural Network classifier to target compressed signal scenarios, where the jets have low transverse momenta. Limits on the cross section of generic new physics models and of the tc + EmissT simplified model will be derived at the 95% confidence level, if no significant deviation from the Standard Model will be found once unblinded. Models featuring light neutralinos of m(~x01) = 1 GeV are expected to be excluded up to m(~t1) ∼ 1050TeV, while signal scenarios with Δm(~t1, ~x01) ∼ mt are excluded up to top-squark masses of 425 GeV. To enable more precise tests of the Standard Model and to expand the discovery reach for new physics, the Large Hadron Collider will be upgraded to drastically increase the collision rate in the context of the High Luminosity Large Hadron Collider project. The innermost part of the ATLAS detector will be replaced with the new Inner Tracker to cope with the higher requirements on radiation tolerance and the larger pile-up. The increased trigger rate and larger occupancy and number of readout channels call for a new readout system. This thesis describes the development and tests of the Optosystem, which is responsible for the recovery, aggregation and electrical-optical conversion of all Inner Tracker Pixel data links. The Optosystem successfully passed a preliminary design review and is scheduled to be installed in ATLAS in the next long shutdown during 2026.

description: Despite the existence of many short-period hot Jupiters, there is not one hot Neptune with an orbital period less than 2.5 days. Here we discuss a cluster analysis of the currently known 106 transiting exoplanets to investigate a possible explanation for this observation. We find two distinct clusters in the mass-density space, one with hot Jupiters with a wide range of orbital periods (0.8--114 days) and a narrow range of planet radii (1.2 +- 0.2 R_J); and another one with a mixture of super-Earths, hot Neptunes and hot Jupiters, exhibiting a surprisingly narrow period distribution (3.7 +- 0.8 days). These two clusters follow different distributions in the period-radius parameter plane. The branch of sub-Jupiter mass exoplanets is censored by the orbital period at large-radii: no planets with mass between 0.02--0.8 M_J or with radius between 0.25--1.0 R_J are known with P_orb<2.5 days. This clustering is not predicted by current theories of planet formation and evolution that we also review briefly.

description: We report on recent calculations of the differential cross section for top-quark pair production at hadron colliders. The results are differential with respect to the top-pair invariant mass and to the partonic scattering angle. In these calculations, which were carried out by employing soft-collinear effective theory techniques, we resummed threshold logarithms up to next-to-next-to-leading logarithmic order. Starting from the differential cross section, it is possible to obtain theoretical predictions for the invariant-mass distribution and the total cross section. We summarize here our results for these observables, and we compare them with the results obtained from different calculational methods.

Powder filters for a dilution fridge scanning tunneling microscope

Publisher: name: University of British Columbia
Year: 2016

description: In this thesis I present the design, construction, and characterization of metal powder microwave filters for a dilution refrigeration scanning tunneling microscope (STM) in the Laboratory for Atomic Imaging Research at the University of British Columbia. Scanning tunneling spectroscopy (STS) measurements performed by the STM are able to reveal features in the local density of states with energy resolution in the μeV regime if the sample and tunnel junction are cooled below 100 mK. The filters described in this work eliminate thermal noise and electromagnetic interference, which decrease energy resolution in STS measurements, up to seemingly indefinite frequency by exploiting the tremendous effective surface area of the metal powder which dissipates radio-frequency power via eddy currents induced in the grains.

description: The quantum Goos-Hänchen shift for ballistic electrons is investigated in a parabolic potential well under a uniform vertical magnetic field. It is found that the Goos-Hänchen shift can be negative as well as positive, and becomes zero at transmission resonances. The beam shift depends not only on the incident energy and incidence angle, but also on the magnetic field and Landau quantum number. Based on these phenomena, we propose an alternative way to realize the spin beam splitter in the proposed spintronic device, which can completely separate spin-up and spin-down electron beams by negative and positive Goos-Hänchen shifts.

description: We report on the noise of a lumped element Direct Current Superconducting Quantum Interference Device amplifier. We show that the noise temperature in the 4 GHz-8 GHz range over ranges of 10's of MHz is below 1 kelvin (three photons of added noise), characterize the overall behavior of the noise as a function of bias parameters, and discuss potential mechanisms which determine the noise performance in this amplifier. We show that this device can provide more than a factor of 10 improvement in practical system noise over existing phase-preserving microwave measurement systems in this frequency band.

description: Physical security is one of the most basic human needs. People care about it for various reasons; for the safety and security of personnel, to protect private assets, to prevent crime, and so forth. With the recent proliferation of AI, various smart physical security systems are getting introduced to the world. Many researchers and engineers are working on developing AI-driven physical security systems that have the capability to identify potential security threats by monitoring and analyzing data collected from various sensors. One of the most popular ways to detect unauthorized entrance to restricted space is using face recognition. With a collected stream of images and a proper algorithm, security systems can recognize faces detected from the image and send an alert when unauthorized faces are recognized. In recent years, there has been active research and development on neural networks for face recognition, e.g. FaceNet is one of the advanced algorithms. However, not much work has been done to showcase what kind of end-to-end system architecture is effective for running heavy-weight computational loads such as neural network inferences. Thus, this study explores different hardware options that can be used in security systems powered by a state-of-the-art face recognition algorithm and proposes that an edge computing based approach can significantly reduce the overall system latency and enhance the system reactiveness. To analyze the pros and cons of the proposed system, this study presents two different end-to-end system architectures. The first system is an edge computing-based system that operates most of the computational tasks at the edge node of the system, and the other is a traditional application server-based system that performs core computational tasks at the application server. Both systems adopt domain-specific hardware, Tensor Processing Units, to accelerate neural network inference. This paper walks through the implementation details of each system and explores its effectiveness. It provides a performance analysis of each system with regard to accuracy and latency and outlines the pros and cons of each system.

We develop a new modelling approach to enhance a recently proposed method to detect increases of contrast enhancing lesions (CELs) on repeated magnetic resonance imaging, which have been used as an indicator for potential adverse events. The method signals patients with unusual increases in CEL activity by estimating the probability of observing CEL counts as large as those observed on a patient's recent scans conditional on the patient's CEL counts on previous scans. This index, computed based on a mixed effect negative binomial regression model, can vary substantially depending on the choice of distribution for the patient-specific random effects. Therefore, we relax this parametric assumption to model the random effects with an infinite mixture of beta distributions, using the Dirichlet process, which effectively allows any form of distribution. As our inference is in the Bayesian framework, we adopt a meta-analytic approach to develop an informative prior based on previous trials. This is particularly helpful at the early stages of a trial. We illustrate our enhanced method with 10 multiple sclerosis (MS) trial datasets, and assess it by simulation studies. Identification of treatment responders is a challenge in comparative studies where a treatment efficacy is measured by various longitudinally-collected continuous and count outcomes. Existing procedures often identify responders based on only a single outcome. We propose to classify patients according to their posterior probability of being a responder estimated based on a multiple outcome mixture model. Our novel model assumes that, conditioning on a cluster label, each longitudinal outcome is from the generalized linear mixed effect model (GLMM), arguably the most popular longitudinal model. As GLMM is a rich class of models, our general procedure enables finding responders comprehensively defined by multiple outcomes from various distributions. We utilize the Monte Carlo expectation-maximization algorithm to obtain the maximum likelihood estimates of our high-dimensional model. We demonstrate the generality of our procedure on two MS trial datasets. Our simulation study shows that incorporating multiple outcomes improves the responder identification performance.

description: We investigate the possibility of using the X-ray telescope (XRT) on board the Swift satellite to improve the current accuracy of the ICM temperature measurements in the region close to the virial radius of nearby clusters. We present the spectral analysis of the Swift XRT observations of 6 galaxy clusters and their temperature profiles in the regions within 0.2-0.6 r200. Four of them are nearby famous and very well studied objects (Coma, Abell 1795, Abell 2029 and PKS0745-19). The remaining two, SWJ1557+35 and SWJ0847+13, at redshift z=0.16 and z=0.36, were serendipitously observed by Swift-XRT. We accurately quantify the temperature uncertainties, with particular focus on the impact of the background scatter (both instrumental and cosmic). We extrapolate these results and simulate a deep observation of the external region of Abell 1795 which is assumed here as a case study. In particular we calculate the expected uncertainties in the temperature measurement as far as r200. We find that, with a fairly deep observation (300 ks), the Swift XRT would be able to measure the ICM temperature profiles in the external regions as far as the virial radius, significantly improving the best accuracy among the previous measurements. This can be achieved thanks to the unprecedented combination of good PSF over the full field of view and very accurate control of the instrumental background. Somehow unexpectedly we conclude that, among currently operating telescope, the Swift-XRT is the only potentially able to improve the current accuracy in plasma temperature measurement at the edges of the cluster potential. This will be true until a newgeneration of low-background and large field of view telescopes, aimed to the study of galaxy clusters, will operate. These observations would be of great importance in developing the observing strategy for suchmissions.

description: An extension of the framework of the Finite Integration Technique (FIT) including dynamic and adaptive mesh refinement is presented. After recalling the standard formulation of the FIT, the proposed mesh adaptation procedure is described. Besides the linear interpolation approach, a novel interpolation technique based on specialized spline functions for approximating the discrete electromagnetic field solution during mesh adaptation is introduced. The standard FIT on a fixed mesh and the new adaptive approach are applied to a simulation test case with known analytical solution. The numerical accuracy of the two methods are shown to be comparable. The dynamic mesh approach is, however, much more efficient. This is also demonstrated for the full scale modeling of the complete RF gun at the Photo Injector Test Facility DESY Zeuthen (PITZ) on a single computer. Results of a detailed design study addressing the effects of individual components of the gun onto the beam emittance using a fully self-consistent approach are presented.

description: We calculate the Casimir interaction between two parallel wires and between a wire and a metall plate. The dielectric properties of the objects are described by the plasma, Drude and perfect metal models. We find that at asymptotically large separation interactions involving plasma wires and/or plates are independent of the material properties, but depend on the dc conductivity $σ$ for Drude wires. Counterintuitively, at intermediate separations the interaction involving Drude wires can become independent of $σ$. At smaller separations, we compute the interaction numerically and observe an approach to the proximity approximation.

description: Cosmic magnetic fields may be generated during early cosmic phase transition, such as the QCD- or electroweak- transitions. The magnitude of the remainder of such fields at the present epoch crucially depends on the exponent $n$ of their (initially super-Hubble) large-scale tail, i.e. B(lambda) ~ lambda^(-n). It has been claimed that causality requires n=5/2, contrary to much earlier claims of n=3/2. Here we analyze this question in detail. First, we note that contrary to current belief, the large-scale magnetic field tail is not established at the phase transition itself, but rather continuoulsy evolves up to the present epoch. Neglecting turbulent flows we find n=7/2, i.e. very strongly suppressed large-scale fields. However, in the inevitable presence of turbulent flows we find that the large-scale magnetic field tail has sufficient time to evolve to that of the fluid turbulence. For white noise fluid turbulence this yields n=3/2 up to a certain scale and n=5/2 beyond for the magnetic field spectrum. This picture is also not changed when primordial viscosity and fluid flow dissipation is taken into account. Appreciable primordial magnetic fields originating from cosmic phase transitions seem thus possible.
