Mobility justice

description: The disability community has been largely underrepresented in the transportation planning process, resulting in accessibility challenges and limitations in access and mobility. Disability rates in the U.S. have increased from 12.5% in 2010 to 13.4% in 2020 and is expected to continue to trend upwards. My dissertation contributes to understanding how disabled people experience the first and last mile segments of public transit trips to access the opportunities they need. To analyze this phenomenon, I frame first and last mile planning for disabled people within the theoretical framework of mobility justice, providing new connections between transportation systems, decisions, and experiences. Scholars can be most effective in advancing justice by shifting power away from planners and agency leaders to capitalize on citizen-led planning goals. This work examines if greater involvement and recognition in the engagement, data analysis, and planning process for the disability community, using a critical lens, can transportation planning for disabled people. My work centers disabled travelers by integrating their experiences throughout the planning process, rather than making assumptions based on insufficient data about pedestrian and transit environments. Using a mixed-methods research design, I compare missing sidewalk infrastructure, public agency planning for transit riders with disabilities, and the travel experiences of disabled transit riders along the first and last mile. I find contextual and intersectional burdens along the first and last mile trip segments for disabled people who use public transit and discuss how spatial and socioeconomic inequities impact these burdens. My dissertation makes three contributions to transportation planning scholarship. I situate first and last mile trips within the complex, socio-political realm of the existing built environment and social systems that link the travel behavior of disabled people with intersectionality, social exclusion, and equitable active transportation. My pedestrian network analysis of missing sidewalk infrastructure uses a novel approach to suggest that first and last mile conditions are needed in measures of access to opportunity. Lastly, I propose that intersectionality, and the complex factors that contribute to a traveler’s identity, need to be prioritized in the transportation planning process.

description: Soil erosion on agricultural land in the United States does not pose an immediate threat to the Nation's ability to produce food and fiber. However, erosion is impairing long-term soil productivity in some areas and is the largest contributor to nonpoint source pollution of the Nation's waterways. Over half of the soil erosion comes from slightly more than a quarter of total cropland acreage. New conservation programs since 1985 have specifically targeted these highly erodible lands, and erosion has significantly declined. Conservation and commodity programs are currently being coordinated to further conservation objectives. This report provides background information on soil use, erosion, and conservation policies and programs; summarizes assessments of economic and environmental effects of erosion; and discusses policies and programs as well as options for their improvement

description: Spin-based silicon quantum electronic circuits offer a scalable platform for quantum computation, combining the manufacturability of semiconductor devices with the long coherence times afforded by spins in silicon. Advancing from current few-qubit devices to silicon quantum processors with upwards of a million qubits, as required for fault-tolerant operation, presents several unique challenges, one of the most demanding being the ability to deliver microwave signals for large-scale qubit control. Here we demonstrate a potential solution to this problem by using a three-dimensional dielectric resonator to broadcast a global microwave signal across a quantum nanoelectronic circuit. Critically, this technique utilizes only a single microwave source and is capable of delivering control signals to millions of qubits simultaneously. We show that the global field can be used to perform spin resonance of single electrons confined in a silicon double quantum dot device, establishing the feasibility of this approach for scalable spin qubit control.

description: The prerogative of mercy is an ancient power to forgive, or temper the punishment of, a legal wrong. In the Middle Ages in England, and later in colonial Australia, it was regularly used to spare the lives of persons found guilty of offences carrying mandatory death sentences. Scholarship and case law considering the prerogative of mercy in the United Kingdom and Australia have almost exclusively focused on its application to pardon persons whose convictions are attended by doubt, irregularity or other infirmity. This article takes a different perspective, highlighting the continued, albeit limited potential application of the prerogative of mercy to alleviate the injustices occasioned by mandatory sentencing. This potential application of the prerogative of mercy is explored in its historical, theoretical and contemporary dimensions, with the contemporary discussion focusing on a recent Australian case study. Drawing upon the case study and the historical and theoretical discussion, this article concludes by making practical recommendations as to how defence lawyers might begin to more regularly petition for mercy in mandatory sentencing cases.

In Section 4, we give a novel calculation for the zero-total energy result.

description: We present spatially resolved BPT mapping of the extended narrow line regions (ENLRs) of seven nearby Seyfert 2 galaxies, using HST narrow band filter imaging. We construct the BPT diagrams using $\leq$ 0.1" resolution emission line images of [O III]$λ$5007, H$α$, [S II]$λ$$λ$6717,6731, and H$β$. By mapping these diagnostic lines according to the BPT classification, we dissect the ENLR into Seyfert, LINER, and star-forming regions. The nucleus and ionization cones are dominated by Seyfert-type emission, which can be interpreted as predominantly photoionization by the active galactic nucleus (AGN). The Seyfert nucleus and ionization cones transition to and are surrounded by a LINER cocoon, extending up to $\sim$ 250 pc in thickness. The ubiquity of the LINER cocoon in Seyfert 2 galaxies suggests that the circumnuclear regions are not necessarily Seyfert-type, and LINER activity plays an important role in Seyfert 2 galaxies. We demonstrate that spatially resolved diagnostics are crucial to understanding the excitation mechanisms in different regions and the AGN-host galaxy interactions.

description: We use perturbative QCD to calculate the parton level cross section for the production of two jets that are far apart in rapidity, subject to a limitation on the total transverse momentum Q0 in the interjet region. We specifically address the question of how to combine the approach which sums all leading logarithms in Q/Q0 (where Q is the jet transverse momentum) with the BFKL approach, in which leading logarithms of the scattering energy are summed. This paper constitutes progress towards the simultaneous summation of all important logarithms. Using an "all orders" matching, we are able to obtain results for the cross section which correctly reproduce the two approaches in the appropriate limits.

description: In July of 2019, the IceCube experiment detected a high-energy neutrino from the direction of the powerful blazar PKS 1502+106. We perform multi-wavelength and multi-messenger modeling of this source, using a fully self-consistent one-zone model that includes the contribution of external radiation fields typical of flat-spectrum radio quasars (FSRQs). We identify three different activity states of the blazar: one quiescent state and two flaring states with hard and soft gamma-ray spectra. We find two hadronic models that can describe the multi-wavelength emission during all three states: a leptohadronic model with a contribution from photo-hadronic processes to X-rays and gamma rays, and a proton synchrotron model, where the emission from keV to 10 GeV comes from proton synchrotron radiation. Both models predict a substantial neutrino flux that is correlated with the gamma-ray and soft X-ray fluxes. Our results are compatible with the detection of a neutrino during the quiescent state, based on event rate statistics. We conclude that the soft X-ray spectra observed during bright flares strongly suggest a hadronic contribution, which can be interpreted as additional evidence for cosmic ray acceleration in the source independently of neutrino observations. We find that more arguments can be made in favor of the leptohadronic model vis-a-vis the proton synchrotron scenario, such as a lower energetic demand during the quiescent state. However, the same leptohadronic model would be disfavored for flaring states of PKS 1502+106 if no IceCube events were found from the direction of the source before 2010, which would require an archival search.

description: The Coulomb deexcitation of $(πp)$ atom in collisions with the hydrogen atom has been studied in the fully quantum mechanical close-coupling approach for the first time. The total Coulomb deexcitation cross-sections of $nl\to n'l'$ transitions and $l$-averaged cross-sections are calculated for $n=3 - 8$ and at the relative energies $E=0.01 - 100$ eV. The strong interaction and vacuum polarization shifts of $ns$-states are taken into account. It is shown that the $Δn > 1$ transitions are very important and make up a substantial fraction of the Coulomb deexcitation cross-section (up to $\sim 47%$).

description: We investigate heating of the cool core of a galaxy cluster through the dissipation of sound waves excited by the activities of the central active galactic nucleus (AGN). Using a weak shock theory, we show that this heating mechanism alone cannot reproduce observed temperature and density profiles of a cluster, because the dissipation length of the waves is much smaller than the size of the core and thus the wave energy is not distributed to the whole core. However, we find that if it is combined with thermal conduction from the hot outer layer of the cluster, the wave heating can reproduce the observational results.

description: Microscopic insight into interactions is a key for understanding the properties of heterogenous interfaces. We analyze local attraction in non-covalently bonded Xe{Cs+ aggregates and monolayers on Cu(111) as well as repulsion upon electron transfer. Using two-photon photoemission spectroscopy, scanning tunneling microscopy, and coupled cluster calculations combined with an image-charge model we explain the intricate impact Xe has on Cs+/Cu(111). We find that attraction between Cs+ and Xe counterbalances the screened Coulomb repulsion between Cs+ ions on Cu(111). Furthermore, we observe that the Cs 6s electron is repelled from Cu(111) due to xenon's electron density. Together, this yields a dual, i.e., attractive or repulsive, response of Xe depending on the positive or negative charge of the respective counterparticle, which emphasizes the importance of the Coulomb interaction in these systems.

The effect of cadence on the rate of neuromuscular fatigue and the slow component of oxygen uptake in cyclists during heavy exercise
Creators: name: Tiessen, Dale A.
Publisher: name: University of British Columbia
Year: 2009

description: This study was designed first to replicate previously published data which examined the effect of cadence on the rate of neuromuscular fatigue of the vastus lateralis muscle in cyclists during heavy exercise and how neuromuscular fatigue was incorporated in the selection of preferred cadence in cyclists. It was the intention of this study to expand previous work and include the examination of other lower limb musculature and detemine a global measure of neuromuscular fatigue for each cadence selected. In addition, the present study sought to assess the affect of cadence on the slow component of oxygen uptake (VO₂ SC) and attempt to establish a relationship between this slow component and a global measure of neuromuscular fatigue. Twelve cyclists performed four sessions of cycling exercise at a power output corresponding to their individual ventilatory thresholds (VT). Each criterion exercise session was performed at a different cadence, ranging from 55 to 100 RPM in 15 RPM steps. A measure of the rate of neuromuscular fatigue was calculated using both a previously published and a novel methodology. Neuromuscular fatigue was evaluated in vastus lateralis, soleus, gastrocnemius, biceps femoris, and gluteus maximus; a global representation was calculated as the sum of the rates of neuromuscular fatigue from all muscle groups. No level of neuromuscular fatigue was observed during the criterion exercise for any of the cadence conditions. There was no relationship between a global representation of neuromuscular fatigue and cadence. The VO₂ SC displayed a significant quadratic trend (p < 0.05) over the range of cadences, with a calculated minimum value at 80.8 RPM. No relationship between neuromuscular fatigue and the VO₂ SC was established, suggesting a different mechanistic basis for these two variables. These data suggested that cyclists do not use a measure of neuromuscular fatigue in the selection of preferred cadence at power outputs corresponding to VT. The cadence minimizing the VO₂ SC did not match the cyclists' preferred cadence, however did corresponded to the pedal frequency previously shown to maximize the efficiency of Type I muscle fibers.

description: We present a three-year series of observations at 24 microns with the Spitzer Space Telescope of the interstellar material in a 200 x 200 arcmin square area centered on Cassiopeia A. Interstellar dust heated by the outward light pulse from the supernova explosion emits in the form of compact, moving features. Their sequential outward movements allow us to study the complicated three-dimensional structure of the interstellar medium (ISM) behind and near Cassiopeia A. The ISM consists of sheets and filaments, with many structures on a scale of a parsec or less. The spatial power spectrum of the ISM appears to be similar to that of fractals with a spectral index of 3.5. The filling factor for the small structures above the spatial wavenumber k ~ 0.5 cycles/pc is only ~ 0.4%.

description: We consider a model where a population of diffusively coupled limit-cycle oscillators, described by the complex Ginzburg-Landau equation, interacts nonlocally via an inertial field. For sufficiently high intensity of nonlocal inertial coupling, the system exhibits birhythmicity with two oscillation modes at largely different frequencies. Stability of uniform oscillations in the birhythmic region is analyzed by means of the phase dynamics approximation. Numerical simulations show that, depending on its parameters, the system has irregular intermittent regimes with local bursts of synchronization or desynchronization.

description: We use Lipatov's high energy effective action to determine the next-to-leading order corrections to Higgs production in the forward region within high energy factorization making use of the infinite top mass limit. Our result is based on an explicit calculation of real corrections combined with virtual corrections determined earlier by Nefedov. As a new element we provide a proper definition of the desired next-to-leading order coefficient within the high energy effective action framework, extending a previously proposed prescription. We further propose a subtraction mechanism to achieve for this coefficient a stable cancellation of real and virtual infra-red singularities in the presence of external off-shell legs. Apart from its relevance for direct phenomenological studies, such as high energy resummation of Higgs + jet configurations, our result will be further of use for the study of transverse momentum dependent factorization in the high energy limit.

It outlines the evolving landscape of online education, particularly in K-12 settings, and the increasing need for effectively prepared online educators.The review addresses the current status of pre-service teacher preparation for online learning, highlighting a significant gap between the growing demand for online education and the preparation of teachers for this modality. It examines the complexity of preparing teachers for online settings, delving into aspects like teacher decision-making, knowledge, skills, practices, epistemologies, and orientations. The review heavily utilises Epistemic Frame Theory to understand teachers' decision-making processes.In response to these challenges, the Monash Virtual School (MVS) model is presented, detailing the design and delivery of a K-12 online teacher professional learning program. This model integrates theoretical foundations like Epistemic Frame Theory and Constructivism, focusing on technological proficiency, pedagogical strategies for online learning, assessment and feedback methods, collaborative learning communities, reflective practice, practical experience, and continuous professional development. These components are designed to prepare PSTs comprehensively for the unique challenges of online education, equipping them with a blend of theoretical knowledge, practical skills, reflective practices, and continuous development.The document concludes by emphasising the importance of these elements in crafting the competencies of PSTs to meet the unique challenges of the dynamic environment of online education. It underlines the integration of Epistemic Frame Theory in developing a holistic set of skills and attributes essential for effective online teaching.

description: Efficient low-variance gradient estimation enabled by the reparameterization trick (RT) has been essential to the success of variational autoencoders. Doubly-reparameterized gradients (DReGs) improve on the RT for multi-sample variational bounds by applying reparameterization a second time for an additional reduction in variance. Here, we develop two generalizations of the DReGs estimator and show that they can be used to train conditional and hierarchical VAEs on image modelling tasks more effectively. First, we extend the estimator to hierarchical models with several stochastic layers by showing how to treat additional score function terms due to the hierarchical variational posterior. We then generalize DReGs to score functions of arbitrary distributions instead of just those of the sampling distribution, which makes the estimator applicable to the parameters of the prior in addition to those of the posterior.

description: Using a simple model, we study the effects of turbulence on the motion of bubbles produced by AGN jet activities in the core of a galaxy cluster. We focus on the turbulence with scales larger then the size of the bubbles. We show that for a bubble pair with an age of ~10^8 yr, the projected angle between the two vectors from the cluster center to the two bubbles should be ~> 90 degree and the ratio of their projected distances from the cluster center should be ~< 2.5, if the velocity and scale of the turbulence are ~250 km s^-1 and ~20 kpc, respectively. The positions of the bubbles observed in the Perseus cluster suggest that the turbulent velocity is ~>100 km s^-1 for the cluster.

description: Two-photon excitation is an attractive means for controlling chemistry in both space and time. Isoenergetic one- and two-photon excitations (OPE and TPE) in non-centrosymmetric molecules are often assumed to reach the same excited state and, hence, to produce similar excited-state reactivity. We compare the solvent-to-solute excited-state proton transfer of the super photobase FR0-SB following isoenergetic OPE and TPE. We find up to 62 % increased reactivity following TPE compared to OPE. From steady-state spectroscopy, we rule out the involvement of different excited states and find that OPE and TPE spectra are identical in non-polar solvents but not in polar ones. We propose that differences in the matrix elements that contribute to the two-photon absorption cross sections lead to the observed enhanced isoenergetic reactivity, consistent with the predictions of our high-level coupled-cluster-based computational protocol. We find that polar solvent configurations favor greater dipole moment change between ground and excited states, which enters the probability for two-photon excitations as the absolute value squared. This, in turn, causes a difference in the Franck-Condon region reached via TPE compared to OPE. We conclude that a new method has been found for controlling chemical reactivity via the matrix elements that affect two-photon cross sections, which may be of great utility for spatial and temporal precision chemistry.

description: Many particle physics models for dark matter self-interactions - motivated to address long-standing challenges to the collisionless cold dark matter paradigm - fall within the semi-classical regime, with interaction potentials that are long-range compared to the de Broglie wavelength for dark matter particles. In this work, we present a quantum mechanical derivation and new analytic formulas for the semi-classical momentum transfer and viscosity cross sections for self-interactions mediated by a Yukawa potential. Our results include the leading quantum corrections beyond the classical limit and allow for both distinguishable and identical dark matter particles. Our formulas supersede the well-known formulas for the momentum transfer cross section obtained from the classical scattering problem, which are often used in phenomenological studies of self-interacting dark matter. Together with previous approximation formulas for the cross section in the quantum regime, our new results allow for nearly complete analytic coverage of the parameter space for self-interactions with a Yukawa potential. We also discuss the phenomenological implications of our results and provide a new velocity-averaging procedure for constraining velocity-dependent self-interactions. Our results have been implemented in the newly released code CLASSICS.

On the Swampland Cobordism Conjecture and Non-Abelian Duality Groups

description: We study the cobordism conjecture of McNamara and Vafa which asserts that the bordism group of quantum gravity is trivial. In the context of type IIB string theory compactified on a circle, this predicts the presence of D7-branes. On the other hand, the non-Abelian structure of the IIB duality group $SL(2,\mathbb{Z})$ implies the existence of additional $[p,q]$ 7-branes. We find that this additional information is instead captured by the space of closed paths on the moduli space of elliptic curves parameterizing distinct values of the type IIB axio-dilaton. This description allows to recover the full structure of non-Abelian braid statistics for 7-branes. Combining the cobordism conjecture with an earlier Swampland conjecture by Ooguri and Vafa, we argue that only certain congruence subgroups $Γ\subset SL(2,\mathbb{Z})$ specifying genus zero modular curves can appear in 8D F-theory vacua. This leads to a successful prediction for the allowed Mordell-Weil torsion groups for 8D F-theory vacua.

description: We focus on the chiral Lagrangian couplings describing radiative corrections to weak semi-leptonic decays and relate them to the decay amplitude of a lepton, computed by Braaten and Li at one loop in the Standard Model. For this purpose, we follow a two-step procedure. A first matching, from the Standard Model to Fermi theory, yields a relevant set of counterterms. The latter are related to chiral couplings thanks to a second matching, from Fermi theory to the chiral Lagrangian, which is performed using the spurion method. We show that the chiral couplings of physical relevance obey integral representations in a closed form, expressed in terms of QCD chiral correlators and vertex functions. We deduce exact relations among the couplings, as well as numerical estimates which go beyond the usual $\log(M\_Z/M\_ρ)$ approximation.

Estimation of visceral adipose tissue and body fat in middle aged men
Creators: name: Warren, Tracy
Publisher: name: University of British Columbia

description: BACKGROUND: Human obesity is associated with a large number or diseases and metabolic complications such as heart disease, diabetes mellitus, hypertentension, gallbladder disease and some types of cancer (Bjorntorp,1990; Depres et al., 1991). Though a causative relationship has not been established between adipose tissue (AT) distribution and these metabolic disturbances, both prospective and epidemiological studies have demonstrated that measures of visceral adipose tissue (VAT) stores are strong predictors of coronary heart disease, diabetes and stroke. Thus the ability to measure abdominal AT, especially VAT, may be important in epidemiological and clinical research. Advanced imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) offer new promise for the visualization and quantification of abdominal A T masses. However, these imaging techniques are expensive, not generally available, and in the case of CT, expose the subjects to ionizing radiation. OBJECTIVE: The aim of this study was to offer a less expensive, quick, safe and accurate method to predict VAT and body fat (BF) using measurements from dual-energy X-ray absorptiometry (DXA) and anthropometry. Eleven men over 50 (50r69 y) participated in this study with a wide range of Body Mass Index's. VAT, subcutaneous abdominal adipose tissue (SAAT) and total abdominal adipose tissue (TAAT) was measured from the 1st to the 5th.lumbar vertebrae using MRI as the criterion measure. BF and trunk fat (TF) were also measured using DXA . RESULTS: Measurements of TF by DXA explained about 70% of the variation in the VAT[sub L1-L5] measured by MRI. TF measured by DXA ( x₁) in combination with the subscapular (x₂) and sum of seven skinfolds (X3) could accurately predict the VAT[sub L1-L5] mass measured by MRI (r² = 0.95, SEE = 8.00 %): VAT (kg) = 0.304(x₁) - 0.0526(x₂) - 0.00707(x₃) + 0.414. A single MRI scan at the L2-L3 intervertebral disk region was found to be the best predictor of VAT[sub L1-L5] mass (r = 0.95). The waist-to-hip ratio was highly correlated with VAT[sub L1-L5] (r = 0.83). This study also found that BF and TF measured by DXA could be accurately predicted with the suprailiac skinfold (x₄) and waist girth (x₅): BF (kg) = 0.341(x₄) + 0.274(x₅) - 15.5 (r² =. 0.96, SEE = 7.18 %). TF (kg) = 0.150(x₄) + 0.199(x₅) - 9.01 (r² = 0.95, SEE = 8.80 %). CONCLUSION: D X A combined with anthropometry can accurately predict V A T mass from the L1-L5 vertebrae, and anthropometry alone can accurately predict BF.and TF in men over 50 y.

description: A two-band model involving the A- and B-valence bands was adopted to analyze the temperature dependent Hall effect measured on N-doped \textit{p}-type ZnO. The hole transport characteristics (mobilities, and effective Hall factor) are calculated using the ``relaxation time approximation'' as a function of temperature. It is shown that the lattice scattering by the acoustic deformation potential is dominant. In the calculation of the scattering rate for ionized impurity mechanism, the activation energy of 100 or 170 meV is used at different compensation ratios between donor and acceptor concentrations. The theoretical Hall mobility at acceptor concentration of $7 \times 10^{18}$ cm$^3$ is about 70 cm$^2$V$^{-1}$s$^{-1}$ with the activation energy of 100 meV and the compensation ratio of 0.8 at 300 K. We also found that the compensation ratios conspicuously affected the Hall mobilities.
