description: The range of the U bosonic coupling constants in neutron star matter is a very interesting but still unsolved problem which has multifaceted influences in nuclear physics, particle physics, astrophysics and cosmology. The combination of the theoretical numerical simulation and the recent observations provides a very good opportunity to solve this problem. In the present work, the range of the U bosonic coupling constants is inferred based on the three relations of the mass-radius, mass-frequency and mass-tidal deformability in neutron star containing hyperons using the GM1, TM1 and NL3 parameter sets under the two flavor symmetries of the SU(6) and SU(3) in the framework of the relativistic mean field theory. Combined with observations from PSRs J1614-2230, J0348+0432, J2215-5135, J0952-0607, J0740+6620, J0030-0451, J1748-2446ad, XTE J1739-285, GW170817 and GW190814 events, our numerical results show that the U bosonic coupling constants may tend to be within the range from 0 to 20 GeV$^{-2}$ in neutron star containing hyperons. Moreover, the numerical results of the three relations obtained by the SU(3) symmetry are better in accordance with observation data than those obtained by the SU(6) symmetry. The results will help us to improve the strict constraints of the equation of state for neutron stars containing hyperons.

description: The emerging field of silicon photonics seeks to unify the high bandwidth of optical communications with CMOS microelectronic circuits. Many components have been demonstrated for on-chip optical communications, including those that utilize the nonlinear optical properties of silicon[1, 2], silicon dioxide[3, 4] and silicon nitride[5, 6]. Processes such as second harmonic generation, which are enabled by the second-order susceptibility, have not been developed since the bulk $χ^{(2)}$ vanishes in these centrosymmetric CMOS materials. Generating the lowest-order nonlinearity would open the window to a new array of CMOS-compatible optical devices capable of nonlinear functionalities not achievable with the?$χ^{(3)}$ response such as electro-optic modulation, sum frequency up-conversion, and difference frequency generation. Here we demonstrate second harmonic (SH) generation in CMOS compatible integrated silicon nitride (Si3N4) waveguides. The $χ^{(2)}$ response is induced in the centrosymmetric material by using the nanoscale structure to break the bulk symmetry. We use a high quality factor Q ring resonator cavity to enhance the efficiency of the nonlinear optical process and detect SH output with milliwatt input powers.

description: Accurately predicting the z-component of the interplanetary magnetic field, particularly during the passage of an interplanetary coronal mass ejection (ICME), is a crucial objective for space weather predictions. Currently, only a handful of techniques have been proposed and they remain limited in scope and accuracy. Recently, a robust machine learning (ML) technique was developed for predicting the minimum value of Bz within ICMEs based on a set of 42 'features', that is, variables calculated from measured quantities upstream of the ICME and within its sheath region. In this study, we investigate these so-called explanatory variables in more detail, focusing on those that were (1) statistically significant; and (2) most important. We find that number density and magnetic field strength accounted for a large proportion of the variability. These features capture the degree to which the ICME compresses the ambient solar wind ahead. Intuitively, this makes sense: Energy made available to CMEs as they erupt is partitioned into magnetic and kinetic energy. Thus, more powerful CMEs are launched with larger flux-rope fields (larger Bz), at greater speeds, resulting in more sheath compression (increased number density and total field strength).
Extrapolation from hypergeometric functions, continued functions and Borel-Leroy transformation; Resummation of perturbative renormalization functions from field theories

description: Physically relevant field-theoretic quantities are usually derived from perturbation techniques. These quantities are solved in the form of an asymptotic series in powers of small perturbation parameters related to the physical system, and calculating higher powers typically results in a higher amount of computational complexity. Such divergent expansions were handled using hyper-geometric functions, continued functions, and Borel-Leroy transforms. Hypergeometric functions are expanded as series, and a rough estimate of next-order information is predicted using information from known orders. Continued functions are used for the resummation of these series. The effective nature of extrapolation using such functions is illustrated by taking different examples in field theories. In the vicinity of second-order phase transitions, critical exponents are the most interesting numerical quantities corresponding to a wide range of physical systems. Using the techniques mentioned in this work, precise estimates are obtained for these critical exponents in ϕ^4 and ϕ^3 field models.

description: The current-voltage characteristics of long and narrow superconducting channels are investigated using the time-dependent Ginzburg-Landau equations for complex order parameter. We found out that the steps in the current voltage characteristic can be associated with bifurcations of either steady or oscillatory solution. We revealed typical instabilities which induced the singularities in current-voltage characteristics, and analytically estimated period of oscillations and average voltage in the vicinity of the critical currents. Our results show that these bifurcations can substantially complicate dynamics of the order parameter and eventually lead to appearance of such phenomena as multistability and chaos. The discussed bifurcation phenomena sheds a light on some recent experimental findings.

A critical ethnographic study of overdose prevention sites as a community-based response to overdose deaths
Creators: name: Olding, Michelle
Publisher: name: University of British Columbia
Year: 2022

description: Background: In response to an increasingly toxic illicit drug supply, drug user activists and allied organizations in British Columbia, Canada have rapidly implemented overdose prevention sites (OPS): sanctioned spaces where people can use drugs while monitored by responders trained to manage overdoses. While emerging research documents multiple health and social benefits of OPS, the distinct expertise, socio-spatial practices, and labour underpinning these interventions have not been studied in-depth. This dissertation uses community-based and critical ethnographic approaches to examine the implementation and operation of OPS in Vancouver as a community-based response to escalating overdose deaths. Methods: Ethnographic fieldwork was conducted at four OPS between July 2018 and March 2020. Ethnographic fieldwork entailed observation of OPS activities, in-depth qualitative interviews with staff and service users, and site-specific focus groups with responders with lived experience. Rooted in critical research approaches, I analysed data to explore how OPS operated to mitigate overdose-related harms within the context of broader structural vulnerabilities such as poverty, criminalization, socio-spatial exclusion, and an increasingly unpredictable and toxic illicit drug supply. Findings: Findings underscored how OPS extended forms of experiential and embodied expertise already existing among people who use drugs (PWUD), while also enabling comprehensive, specialized, and collective practices to emerge around overdose management. The overdose response function of sites had to be negotiated with other survival uses of the space by low-income services users who lacked access to safe, affordable housing and were regularly displaced from public space by urban governance techniques. Given their embeddedness within and deep knowledge of the communities they served, OPS workers were able to rapidly implement and adapt operational practices to address the broader social and health vulnerabilities of service users. However, the emotional burden and precarity of OPS labour intersected with other dimensions of structural vulnerability (e.g., poverty, criminalization) to place OPS workers with lived experience at heightened risk of burnout, with adverse impacts on service delivery. Conclusion: This dissertation highlights the importance of overdose prevention services being designed by and leveraging the expertise of structurally vulnerable PWUD, while also indicating the need for policy changes to better support community-based overdose response.

description: A simple version of exact finite dimensional reduction for the variational setting of mechanical systems is presented. It is worked out by means of a thorough global version of the implicit function theorem for monotone operators. Moreover, the Hessian of the reduced function preserves all the relevant information of the original one, by Schur's complement, which spontaneously appears in this context. Finally, the results are straightforwardly extended to the case of a Dirichlet problem on a bounded domain.

description: Solar filaments are dense and cool plasma clouds in the solar corona. They are supposed to be supported in a dip of coronal magnetic field. However, the models are still under argument between two types of the field configuration; one is the normal polarity model proposed by Kippenhahn & Schlueter (1957), and the other is the reverse polarity model proposed by Kuperus & Raadu (1974). To understand the mechanism that the filaments become unstable before the eruption, it is critical to know the magnetic structure of solar filaments. In this study, we performed the spectro-polarimetric observation in the He I (10830 angstrom) line to investigate the magnetic field configuration of dark filaments. The observation was carried out with the Domeless Solar Telescope at Hida Observatory with a polarization sensitivity of 3.0x10^-4. We obtained 8 samples of filaments in quiet region. As a result of the analysis of full Stokes profiles of filaments, we found that the field strengths were estimated as 8 - 35 Gauss. By comparing the direction of the magnetic field in filaments and the global distribution of the photospheric magnetic field, we determined the magnetic field configuration of the filaments, and we concluded that 1 out of 8 samples have normal polarity configuration, and 7 out of 8 have reverse polarity configuration.

description: We investigate the dynamics of two miscible superfluids experiencing fast counterflow in a narrow channel. The superfluids are formed by two distinguishable components of a trapped dilute-gas Bose-Einstein condensate (BEC). The onset of counterflow-induced modulational instability throughout the cloud is observed and shown to lead to the proliferation of dark-dark vector solitons. These solitons, which we observe for the first time in a BEC, do not exist in single-component systems, exhibit intriguing beating dynamics and can experience a transverse instability leading to vortex line structures. Experimental results and multi-dimensional numerical simulations are presented.

description: The transverse nuclear magnetic resonance (NMR) decays of $^{129}$Xe in polycrystalline xenon were recently shown to have a universal property: in the long-time regime these decays all converge to the same sinusoidally modulated exponential function irrespective of the initial transverse spin configuration prepared by a sequence of one or more radio frequency pulses. The present work constitutes a more comprehensive survey of this phenomenon. It examines transverse decays for several different isotopic concentrations of $^{129}$Xe, employs additional pulse sequences, and performs similar measurements in a different material: $^{19}$F in single-crystal and polycrystalline CaF$_2$. We additionally verified the polycrystalline nature of our frozen xenon samples by X-ray diffraction measurements. With the possible exception of polycrystalline CaF$_2$ where the observation of the long-time behavior is limited by the experimental resolution, all these systems display the long-time universal behavior characterized by particular values of the exponential decay coefficient and beat frequency that were unique for each lattice. This behavior has been theoretically predicted based on the notion of microscopic chaos.

description: Analyses have found a "haze" of anomalous microwave emission surrounding the Galactic Center in the WMAP sky maps. A recent study using Fermi data detected a similar haze in the gamma-ray. Several studies have modeled these hazes as radiation from the leptonic byproducts of dark matter annihilations, and arguably no convincing astrophysical alternative has been suggested. We discuss the characteristics of astrophysical cosmic ray sources that could potentially explain this microwave and gamma-ray emission. The most promising astrophysical scenarios involve cosmic ray sources that are clustered such that many fall within ~1 kpc of the Galactic Center. For example, we show that several hundred Galactic Center supernovae in the last million years plus a diffusion-hardened electron spectrum may be consistent with present constraints on this emission. Alternatively, it could be due to a burst of activity probably associated with Sagittarius A* occurring ~1 Myr ago and producing >10^51 erg in cosmic ray electrons. Different models predict different trends for the spectral index of the microwave and gamma-ray spectrum as a function of angle from the Galactic Center that should be robust to cosmic ray propagation uncertainties. In particular, if the haze is from dark matter annihilations, it should have a very hard microwave and gamma-ray spectrum for which the spectral shape does not change significantly with angle, which we argue would be difficult to achieve with any astrophysical mechanism. Observations with the Planck and Fermi satellites can distinguish between viable haze models using these signatures.

Stroke and white matter hyperintensities : investigating lesion impacts on cognition and white matter structure
Creators: name: Ferris, Jennifer Kathleen
Publisher: name: University of British Columbia
Year: 2022

description: After stroke many individuals experience chronic cognitive and motor impairments, and it is difficult to predict the severity of these impairments. In addition to the stroke infarct, age-related vascular damage occurs in the brain, notably from white matter hyperintensities (WMHs). WMHs relate to cognitive decline in older adults and share common cardiovascular risk factors with stroke. Yet, little work has considered the combined impact of WMHs and stroke lesions on brain structure and behaviour. This thesis employed diffusion tensor imaging (DTI); a neuroimaging technique that measures the microstructure of white matter pathways. We investigated how WMHs and stroke lesions are associated with cognitive outcomes and white matter structure in older adults and individuals with chronic stroke. First, we evaluated candidate white matter markers of processing speed and executive function using the trail making test (TMT). Among a group of white matter tracts, DTI microstructure of the anterior thalamic radiation emerged as a predictor of TMT performance in older adults and individuals with chronic stroke. Next, we tested the sensitivity of DTI to the presence of lesions in white matter tracts. We found that tract microstructure related to WMH lesion load in older adults and related to both WMH and stroke lesion load in individuals with chronic stroke. Further, we observed focal impacts of WMHs and stroke lesions on tract microstructure along the length of white matter tracts. Finally, we used DTI in combination with myelin water imaging to evaluate white matter structure in WMHs and surrounding white matter. We found that white matter adjacent to WMHs exhibits characteristics of a transitionary stage between healthy white matter and WMH lesions. This was observed in imaging metrics sensitive to interstitial fluid, but not in the specific marker of myelin concentration derived from myelin water imaging. In summary, DTI microstructure is a potential biomarker of cognitive performance, and a sensitive index of structural cerebrovascular damage to white matter tracts. However, the physiological implications of lesion-related changes to DTI metrics must be interpreted with caution. This thesis contributes foundational knowledge of the application and limitations of DTI as a structural biomarker in cerebrovascular disease.

description: We report the discovery and orbital characterization of three new transiting warm giant planets. These systems were initially identified as presenting single transit events in the light curves generated from the full frame images of the Transiting Exoplanet Survey Satellite (TESS). Follow-up radial velocity measurements and additional light curves were used to determine the orbital periods and confirm the planetary nature of the candidates. The planets orbit slightly metal-rich late F- and early G-type stars. We find that TOI 4406b has a mass of $M_P$= 0.30 $\pm$ 0.04 $M_J$ , a radius of $R_P$= 1.00 $\pm$ 0.02 $R_J$ , and a low eccentricity orbit (e=0.15 $\pm$ 0.05) with a period of P= 30.08364 $\pm$ 0.00005 d . TOI 2338b has a mass of $M_P$= 5.98 $\pm$ 0.20 $M_J$ , a radius of $R_P$= 1.00 $\pm$ 0.01 $R_J$ , and a highly eccentric orbit (e= 0.676 $\pm$ 0.002 ) with a period of P= 22.65398 $\pm$ 0.00002 d . Finally, TOI 2589b has a mass of $M_P$= 3.50 $\pm$ 0.10 $M_J$ , a radius of $R_P$= 1.08 $\pm$ 0.03 $R_J$ , and an eccentric orbit (e = 0.522 $\pm$ 0.006 ) with a period of P= 61.6277 $\pm$ 0.0002 d . TOI 4406b and TOI 2338b are enriched in metals compared to their host stars, while the structure of TOI 2589b is consistent with having similar metal enrichment to its host star.

description: Confinement and wall effects are known to affect the kinematics and propulsive characteristics of swimming microorganisms. When a solid body is dragged through a viscous fluid at constant velocity, the presence of a wall increases fluid drag, and thus the net force required to maintain speed has to increase. In contrast, recent optical trapping experiments have revealed that the propulsive force generated by human spermatozoa is decreased by the presence of boundaries. Here, we use a series of simple models to analytically elucidate the propulsive effects of a solid boundary on passively actuated filaments and model flagella. For passive flexible filaments actuated periodically at one end, the presence of the wall is shown to increase the propulsive forces generated by the filaments in the case of displacement-driven actuation, while it decreases the force in the case of force-driven actuation. In the case of active filaments as models for eukaryotic flagella, we demonstrate that the manner in which a solid wall affects propulsion cannot be known a priori, but is instead a nontrivial function of the flagellum frequency, wavelength, its material characteristics, the manner in which the molecular motors self-organize to produce oscillations (prescribed activity model or self-organized axonemal beating model), and the boundary conditions applied experimentally to the tethered flagellum. In particular, we show that in some cases, the increase in fluid friction induced by the wall can lead to a change in the waveform expressed by the flagella which results in a decrease in their propulsive force.

description: Results of a large program of spectroscopic monitoring of nearby solar-type stellar hierarchical systems using the CHIRON echelle spectrograph at the 1.5 m telescope are summarized. Ten papers of this series contain 102 spectroscopic orbits and substantially contribute to the knowledge of periods and eccentricties, providing input for the study of their formation and early evolution. Radial velocities of additional 91 targets without CHIRON orbits (members of wide physical pairs) are published here. Our results are compared to the recent Gaia Non-Single Star (NSS) catalog, revealing its strengths and weaknesses. The NSS provides orbital periods for 31 objects of the CHIRON sample (about one third). Of the 22 spectroscopic NSS orbits in common, 14 are in good agreement with CHIRON, the rest have reduced velocity amplitudes or other problems. Hence ground-based monitoring gives, so far, a more accurate and complete picture of nearby hierarchies than Gaia. The distribution of inner periods in hierarchical systems is non-monotonic, showing a shallow minimum in the 30-100 days bin and a strong excess at shorter periods, compared to the smooth distribution of simple binaries in the field. The period-eccentricity diagram of inner subsystems updated by this survey, recent literature, and Gaia, displays an interesting structure.

description: The Kondo breakdown scenario has been claimed to allow the $T$-linear resistivity in the vicinity of the Kondo breakdown quantum critical point, two cornerstones of which are the dynamical exponent $z = 3$ quantum criticality for hybridization fluctuations in three dimensions and irrelevance of vertex corrections for transport due to the presence of localized electrons. We revisit the issue of vertex corrections in electrical transport coefficients. Assuming that two kinds of bosonic degrees of freedom, hybridization excitations and gauge fluctuations, are in equilibrium, we derive coupled quantum Boltzmann equations for two kinds of fermions, conduction electrons and spinons. We reveal that vertex corrections play a certain role, changing the $T$-linear behavior into $T^{5/3}$ in three dimensions. However, the $T^{5/3}$ regime turns out to be narrow, and the $T$-linear resistivity is still expected in most temperature ranges at the Kondo breakdown quantum critical point in spite of the presence of vertex corrections. We justify our evaluation, showing that the Hall coefficient is not renormalized to remain as the Fermi-liquid value at the Kondo breakdown quantum critical point.
The strategic compulsion of offending states to compliment the virtues of international law : Kremlin's Ukraine Policy

description: Since the illegal annexation of Crimea in 2014, studies on the Kremlin’s foreign policy have reached Cold War levels. According to the dominant majority, composed of realist scholars, the Kremlin had executed an expected move by retaliating against Western expansion toward Ukraine. However, despite the apparent influence of realism on the Kremlin’s Ukraine policy, scholars and policymakers neglected to predict the eagerness of the Russian Federation to avoid damaging the existing international legal system, even while systematically violating it. During the two military offensives against Ukraine in less than a decade, Moscow has put great effort into legitimizing its actions with international law. And when it was unable to do so, the Kremlin has sought to avoid challenging the existing international order by identifying its offensive as a “special military operation.” This thesis aims to show that, despite their proactive policy agendas, powerful states are eager to legitimize their actions with international law, and when they cannot, they do not disregard nor challenge it. By drawing on a diversity of examples from four different case studies in which the United States or the Russian Federation played a major role, this study aims to present the commitment of powerful states to follow and preserve the existing international system, for their long-term interests.

description: Iterated commutators of multilinear Calderon-Zygmund operators and pointwise multiplication with functions in $BMO$ are studied in products of Lebesgue spaces. Both strong type and weak end-point estimates are obtained, including weighted results involving the vectors weights of the multilinear Calderon-Zygmund theory recently introduced in the literature. Some better than expected estimates for certain multilinear operators are presented too.
description: A typo in the original manuscript lead to overlook a gap in one of our arguments which has been fixed. The new arguments are provided in the proof of Theorem 3.1 in Section 3. With the exception of some new notation introduced and some minor changes in wording in a few places, those new details are the only modifications to the original manuscript

description: Three important properties in aggregation theory are investigated, namely horizontal min-additivity, horizontal max-additivity, and comonotonic additivity, which are defined by certain relaxations of the Cauchy functional equation in several variables. We show that these properties are equivalent and we completely describe the functions characterized by them. By adding some regularity conditions, these functions coincide with the Lovász extensions vanishing at the origin, which subsume the discrete Choquet integrals. We also propose a simultaneous generalization of horizontal min-additivity and horizontal max-additivity, called horizontal median-additivity, and we describe the corresponding function class. Additional conditions then reduce this class to that of symmetric Lovász extensions, which includes the discrete symmetric Choquet integrals.
title: Gender inequality in long-term marriages : Negotiation and renegotiation of gendered responsibilities by married couples aged 50-70
Creators: name: Mason, J
Publisher: name: University of Kent
Year: 2022

description: This thesis adopts the kind of perspective which investigates inequality in the 'personal' sphere of marriage by reference to links between the interpersonal and structural or patterned inequalities. It is based on a study of 18 couples aged between 50 and 70 who are in the process of negotiating various transitions in their lives. These have a disruptive potential for the ways in which inequality has been observed to be constructed in younger marriages, and form the focus for a discussion about negotiations and renegotiations of gender inequalities. Gendered responsibility is identified as the crucial structuring component of gender inequality. It involves women's servicing of, caring for, and maintenance of the wellbeing of their husbands and families, and men's provision and protection for their families. Negotiations in the lives of the couples, although producing meaningful changes in gender divisions, did not challenge the relations of gendered responsibilities and hence did not overcome inequality. In fact, those responsibilities gained a new significance and priority in the light of the life course positions of the couples in the study . The couples were found to be making sense of the social material which formed the context of their 'private' lives through various common sense ideologies. These ideologies helped to create an aura of inevitability and immutability about gendered responsibilities and helped to preclude their renegotiation. Essentially, these helped to sustain a taken—for granted fabric of married life, encompassing a particular kind of gender division whose consequence was gender inequality.

description: It is shown that attempts to accurately deduce the magnetic penetration depth of overdoped BaFe_{1.82}Co_{0.18}As2 single crystals by transverse-field muon spin rotation (TF-muSR) are thwarted by field-induced magnetic order and strong vortex-lattice disorder. We explain how substantial deviations from the magnetic field distribution of a nearly perfect vortex lattice by one or both of these factors is also significant for other iron-based superconductors, and this introduces considerable uncertainty in the values of the magnetic penetration depth obtained by TF-muSR.

description: We present here the signal-to-noise (S/N) calculator developed for the Colorado Ultraviolet Transit Experiment (CUTE) mission. CUTE is a 6U CubeSat operating in the near-ultraviolet (NUV) observing exoplanetary transits to study their upper atmospheres. CUTE was launched into a low-Earth orbit in September 2021 and it is currently gathering scientific data. As part of the S/N calculator, we also present the error propagation for computing transit depth uncertainties starting from the S/N of the original spectroscopic observations. The CUTE S/N calculator is currently extensively used for target selection and scheduling. The modular construction of the CUTE S/N calculator enables its adaptation and can be used also for other missions and instruments.

description: Prion diseases {\it (e.g. Creutzfeldt-Jakob disease (CJD), variant CJD (vCJD), Gerstmann-Str$\ddot{\text{a}}$ussler-Scheinker syndrome (GSS), Fatal Familial Insomnia (FFI) and Kuru in humans, scrapie in sheep, bovine spongiform encephalopathy (BSE or `mad-cow' disease) and chronic wasting disease (CWD) in cattles)} are invariably fatal and highly infectious neurodegenerative diseases affecting humans and animals. However, by now there have not been some effective therapeutic approaches or medications to treat all these prion diseases. Rabbits, dogs, and horses are the only mammalian species reported to be resistant to infection from prion diseases isolated from other species. Recently, the $β$2-$α$2 loop has been reported to contribute to their protein structural stabilities. The author has found that rabbit prion protein has a strong salt bridge ASP177-ARG163 (like a taut bow string) keeping this loop linked. This paper confirms that this salt bridge also contributes to the structural stability of horse prion protein. Thus, the region of $β$2-$α$2 loop might be a potential drug target region. Besides this very important salt bridge, other four important salt bridges GLU196-ARG156-HIS187, ARG156-ASP202 and GLU211-HIS177 are also found to greatly contribute to the structural stability of horse prion protein. Rich databases of salt bridges, hydrogen bonds and hydrophobic contacts for horse prion protein can be found in this paper.

description: Crescent-shaped structures in transition disks hold the key to studying the putative companions to the central stars. The dust dynamics, especially that of different grain sizes, is important to understanding the role of pressure bumps in planet formation. In this work, we present deep dust continuum observation with high resolution towards the Oph IRS 48 system. For the first time, we are able to significantly trace and detect emission along $95\%$ of the ring crossing the crescent-shaped structure. The ring is highly eccentric with an eccentricity of $0.27$. The flux density contrast between the peak of the flux and its counter part along the ring is $\sim 270$. In addition, we detect a compact emission toward the central star. If the emission is an inner circumstellar disk inside the cavity, it has a radius of at most a couple of astronomical units with a dust mass of $1.5\times 10^{-8}\rm\, M_\odot$, or $0.005\rm\, M_\oplus$. We also discuss the implications of the potential eccentric orbit on the proper motion of the crescent, the putative secondary companion, and the asymmetry in velocity maps.
