description: Objectives. We examined whether frequent drug use increases the likelihood of subsequent sexual or physical intimate partner violence (IPV) and whether IPV increases the likelihood of subsequent frequent drug use. Methods. A random sample of 416 women on methadone was assessed at baseline (wave 1) and at 6 months (wave 2), and 12 months (wave 3) following the initial assessment. Propensity score matching and multiple logistic regression were employed. Results. Women who reported frequent crack use at wave 2 were more likely than non-drug using women to report IPV at wave 3 (odds ratio [OR]=4.4; 95% confidence interval [CI]=2.1, 9.1; P
On the local nature and scaling of chaos in weakly nonlinear disordered chains

description: The dynamics of a disordered nonlinear chain can be either regular or chaotic with a certain probability. The chaotic behavior is often associated with the destruction of Anderson localization by the nonlinearity. In the presentwork it is argued that at weak nonlinearity chaos is nucleated locally on rare resonant segments of the chain. Based on this picture, the probability of chaos is evaluated analytically. The same probability is also evaluated by direct numerical sampling of disorder realizations and quantitative agreement between the two results is found.

description: The pharmaceutical industry is undergoing a period of uncertainty. Profits are being squeezed by increasing costs and competitive pressures, and new drug production is slowing down. This Perspective reviews two policies that could assist in realigning incentives toward genuine innovation while also keeping drug spending growth under check. Value-based pricing can incentivize genuinely new discoveries and align research and development with social welfare. Public funding of clinical trials likewise can reduce both pharmaceutical costs and prices and direct research effort in a manner that is more socially productive than the current state of affairs.
Business Trends & Challenges in Islamic FinTech: A Systematic Literature Review

description: Background: This systematic literature review (SLR) study is on Islamic financial technology (FinTech) business trends and challenges. It follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. This research identifies the gaps in Islamic FinTech, which require further studies. Moreover, it highlights the issues raised during the pandemic coronavirus disease 2019 (COVID-19).
 Methods: This study is based on the FinTech business model (BM) classifications by Lee & Shin and Imerman & Fabozzi. Furthermore, the set of challenges used in this study is adopted from research by Lee & Shin and Li & Xu. The Scopus database was used to collect data using nine keywords. Articles and review papers published between 2016 and 2022 were included. Studies that were not published in English and those with no ranking journals were excluded. The results were presented using bibliometric analysis.
 Results: The results showed 36 articles discussing Islamic FinTech business trends and challenges, and most of these studies are conducted on FinTech crowdfunding vertical BM. By contrast, the most dominant horizontal BMs are FinTech regulation and FinTech funding BMs. The top challenge found in this study is the regulation management challenge. Moreover, remarkably dominating articles and reviews published in 2020 and 2021 discuss COVID-19.
 Conclusions: This study concluded that many horizontal BMs were not covered in Islamic FinTech, especially horizontal technology BMs. Investment, property and insurance BMs are examples of unavailable articles. Islamic FinTech is considered a promising field due to the size of the opportunities it presents, the available capital, and the great demand for banking and financial products that comply with the Sharia. This study will help the Islamic FinTech industry grow and predict the demand, and provide an alternative to conventional banking FinTech and further boost the technological progress in the financial industry.

description: We calculate the acoustic radiation force from an ultrasound wave on a compressible, spherical particle suspended in a viscous fluid. Using Prandtl--Schlichting boundary-layer theory, we include the kinematic viscosity of the solvent and derive an analytical expression for the resulting radiation force, which is valid for any particle radius and boundary-layer thickness provided that both of these length scales are much smaller than the wavelength of the ultrasound wave (mm in water at MHz frequencies). The acoustophoretic response of suspended microparticles is predicted and analyzed using parameter values typically employed in microchannel acoustophoresis.

description: This paper examines access to external financing in the privatization context and provides new evidence on the effects of financing constraints on performance and investment. Ownership reforms increase firms' reliance on external financing. Empirically, performance and investment changes around ownership reforms are increasing in country-level measures of access to credit. The presence of a severe prior public financing constraint contributes to stronger investment growth after privatization. Privatized enterprises do not outperform publicly owned industries, all else given. Our analyses rely on new international sector- and firm-level data and correct for potential endogeneity of ownership changes.

description: The isomeric and β decays of the N = Z +2 nucleus 96Ag were investigated at NSCL. A cascade of γ-ray transitions originating from the de-excitation of a μs isomer was observed for the first time and was found in coincidence with two previously-known transitions with energies of 470 and 667 keV. The isomeric half-life was determined as 1.45(7) μs, more precise than previously reported. The existence of a second, longer-lived μs isomer, associated with a 743-keV transition, is also proposed here. Shell model results within the (p_{3/2}p_{1/2}f_{5/2}g_{9/2}) model space, using the jj44b interaction, reproduced level energies and isomeric decay half-lives reasonably well.

description: Social network analysis has emerged as a technique in sociology. However, it has become more and more interesting to researchers of other fields. The flexibility and scalability supported by the new technology encouraged the extension of the social network technology to handle new applications. A social network is defined as a set of nodes and a set of links connecting them. Social network analysis is the task of analyzing a social network with the purpose of gaining some information about the network such as patterns of connection or important nodes. However, there are a lot of applications where only raw data is available. Usually, the data sets contain data objects with their set of features. In this work, we propose an approach to construct a social network fom a raw data set. The approach is based on the assumption that if two objects are similar, there is a higher probability that they are placed in the same cluster in different clustering solutions. Based on this assumption, we use a multi-objective genetic algorithm approach to find different solutions for partitioning the data objects. The actors of the final social network are the data objects, and the link between them shows the ratio of partitioning solutions that the objects are placed in the same cluster. This work is implemented in NetDriller, a powerful social network analysis tool developed at Data Mining group at the University of Calgary. We show the validity of our approach by evaluating both the intermediate clustering results and the constructed social network in a case study on stock market.

description: The top quark is the heaviest of the six quarks of the Standard Model. Precise knowledge of its mass is important for imposing constraints on a number of physics processes, including interactions of the as yet unobserved Higgs boson. The Higgs boson is the only missing particle of the Standard Model, central to the electroweak symmetry breaking mechanism and generation of particle masses. In this Review, experimental measurements of the top quark mass accomplished at the Tevatron, a proton-antiproton collider located at the Fermi National Accelerator Laboratory, are described. Topologies of top quark events and methods used to separate signal events from background sources are discussed. Data analysis techniques used to extract information about the top mass value are reviewed. The combination of several most precise measurements performed with the two Tevatron particle detectors, CDF and \D0, yields a value of $\Mt = 173.2 \pm 0.9$ GeV/$c^2$.

Vertical Structure and Coronal Power of Accretion Disks Powered by MRI Turbulence

description: In this paper we consider two outstanding intertwined problems in modern high-energy astrophysics: (1) the vertical thermal structure of an optically thick accretion disk heated by the dissipation of magnetohydrodynamic (MHD) turbulence driven by the magneto-rotational instability (MRI), and (2) determining the fraction of the accretion power released in the corona above the disk. For simplicity, we consider a gas-pressure-dominated disk and assume a constant opacity. We argue that the local turbulent dissipation rate due to the disruption of MRI channel flows by secondary parasitic instabilities should be uniform across most of the disk, almost up to the disk photosphere. We then obtain a self-consistent analytical solution for the vertical thermal structure of the disk, governed by the balance between the heating by MRI turbulence and the cooling by radiative diffusion. Next, we argue that the coronal power fraction is determined by the competition between the Parker instability, viewed as a parasitic instability feeding off of MRI channel flows, and other parasitic instabilities. We show that the Parker instability inevitably becomes important near the disk surface, leading to a certain lower limit on the coronal power. While most of the analysis in this paper focuses on the case of a disk threaded by an externally imposed vertical magnetic field, we also discuss the zero-net-flux case, in which the magnetic field is produced by the MRI dynamo itself, and show that most of our arguments and conclusions should be valid in this case as well.

description: Livestock – large carnivore coexistence occurs within a broader context of social-ecological systems, specifically ranches and rural communities. Coexistence practitioners can be more effective by expanding from a direct focus on carnivores and predation-prevention tools to livestock management context. Ranchers can apply many of the same approaches that work for rangeland health and livestock production to reduce conflicts with large carnivores. The central anti-predator behavior of wild grazing animals is to form large, dense herds that then move around the landscape to seek fresh forage, avoid fouled areas, and escape predators. They also have their young in short, synchronized birthing seasons (predator satiation). Grazing management involving high stocking density and frequent movement, such as rotational grazing and herding with low-stress livestock handling, can improve rangeland health and livestock production, by managing the distribution of grazing across time, space, and plant species. Short calving seasons can increase livestock production and reduce labor inputs, especially when timed to coincide with peak availability of forage quality. Livestock management approaches based on anti-predator behaviors of wild ungulates, including grazing management and synchronized calving, may directly and synergistically reduce predation risk—while simultaneously establishing a management context in which other predation-prevention practices and tools can be used more effectively. Pilot projects on summer cattle range in the U.S. Northern Rockies involving increased stocking density through intensification of existing grazing rotations with herding suggest methods that can be used to improve grazing distribution and prevent depredations.

description: We investigate the entanglement properties of the valence-bond-solid (VBS) state defined on two-dimensional lattices, which is the exact ground state of the Affleck-Kennedy-Lieb-Tasaki model. It is shown that the entanglement entropy obeys an area law and the non-universal prefactor of the leading term is strictly less than $\ln 2$. The analysis of entanglement spectra for various lattices reveals that the reduced density matrix associated with the VBS state is closely related to a thermal density matrix of a {\it holographic} spin chain, whose spectrum is reminiscent of that of the spin-1/2 Heisenberg chain. This correspondence is further supported by comparing the entanglement entropy in the holographic spin chain with conformal field theory predictions.

description: There is a broad class of astrophysical sources that produce detectable, transient, gravitational waves. Some searches for transient gravitational waves are tailored to known features of these sources. Other searches make few assumptions about the sources. Typically events are observable with multiple search techniques. This work describes how to combine the results of searches that are not independent, treating each search as a classifier for a given event. This will be shown to improve the overall sensitivity to gravitational-wave events while directly addressing the problem of consistent interpretation of multiple trials.

In a second time we prove that Ghoussoub and Moameni's theorem is true in L², and find the decomposition for particular example : u(x) = |x-1/2|.

description: Objectives. We examined the relationships between mobility characteristics and sexual risk behaviors among male and female migrant market vendors in Almaty, Kazakhstan. Methods. Participants completed a structured interview covering sociodemographics, mobility characteristics, sexual behaviors, and biomarkers for HIV, HCV, and syphilis. We used multivariate analyses to examine associations between mobility patterns and HIV risks after adjusting for sociodemographics. Results. Longer duration of a participant's last trip outside Almaty increased the odds of reporting multiple sexual partners. More frequent travel to visit family or friends was associated with multiple sexual partners and unprotected sex with steady partners. More frequent travel to buy goods in the past year was associated with multiple sexual partners. Men who traveled more often to buy goods were more likely to have purchased sex within the previous 90 days. Conclusions. Relationships between mobility patterns and sexual risk behaviors underscore the need for HIV-prevention strategies targeting the specific transmission dynamics that migrant vendors are likely to present.
Is there Correlation between Fine Structure and Dark Energy Cosmic Dipoles?

description: We present a detailed analysis (including redshift tomography) of the cosmic dipoles in the Keck+VLT quasar absorber and in the Union2 SnIa samples. We show that the fine structure constant cosmic dipole obtained through the Keck+VLT quasar absorber sample at $4.1σ$ level is anomalously aligned with the corresponding dark energy dipole obtained through the Union2 sample at $2σ$ level. The angular separation between the two dipole directions is $11.3^\circ \pm 11.8^\circ$. We use Monte Carlo simulations to find the probability of obtaining the observed dipole magnitudes with the observed alignment, in the context of an isotropic cosmological model with no correlation between dark energy and fine structure constant $α$. We find that this probability is less than one part in $10^6$. We propose a simple physical model (extended topological quintessence) which naturally predicts a spherical inhomogeneous distribution for both dark energy density and fine structure constant values. The model is based on the existence of a recently formed giant global monopole with Hubble scale core which also couples non-minimally to electromagnetism. Aligned dipole anisotropies would naturally emerge for an off-centre observer for both the fine structure constant and for dark energy density. This model smoothly reduces to \lcdm for proper limits of its parameters. Two predictions of this model are (a) a correlation between the existence of strong cosmic electromagnetic fields and the value of $α$ and (b) the existence of a dark flow on Hubble scales due to the repulsive gravity of the global defect core (`Great Repulser') aligned with the dark energy and $α$ dipoles. The direction of the dark flow is predicted to be towards the spatial region of lower accelerating expansion. Existing data about the dark flow are consistent with this prediction.

description: Perpetrators of male-to-female intimate partner violence (IPV) may be likely to have multiple service needs, the extent of which may vary with respect to criminal justice involvement. The salience of the criminal justice system and the potential impact on service needs due to arrest and incarceration is underscored given the association between substance use and IPV. This study utilized a sample of men in methadone treatment who perpetrated male-to-female IPV in order to examine associations between criminal justice involvement and perceived additional service need(s). Results indicate that the likelihood of having service needs significantly increased as time since most recent arrest or incarceration decreased. These findings highlight the need and potential benefit that can be derived from greater coordination amongst the criminal justice, IPV prevention, and drug treatment systems and service providers.

description: The geometrical structure known as the Tulczyjew triple has proved to be very useful in describing mechanical systems, even those with singular Lagrangians or subject to constraints. Starting from basic concepts of variational calculus, we construct the Tulczyjew triple for first-order Field Theory. The important feature of our approach is that we do not postulate {\it ad hoc} the ingredients of the theory, but obtain them as unavoidable consequences of the variational calculus. This picture of Field Theory is covariant and complete, containing not only the Lagrangian formalism and Euler-Lagrange equations but also the phase space, the phase dynamics and the Hamiltonian formalism. Since the configuration space turns out to be an affine bundle, we have to use affine geometry, in particular the notion of the affine duality. In our formulation, the two maps $α$ and $β$ which constitute the Tulczyjew triple are morphisms of double structures of affine-vector bundles. We discuss also the Legendre transformation, i.e. the transition between the Lagrangian and the Hamiltonian formulation of the first-order field theory

description: In this study, sexual risk behavior of 104 incarcerated female drug users is examined. Findings demonstrate that incarcerated women who use drugs are at high risk for human immunodeficiency virus (HIV) infection because of their behavior prior to arrest. During the month prior to arrest, the majority of respondents were sexually active. Half reported past sexual contacts with injecting drug users, and more than one-third had traded sex for money or drugs. Consistent with other studies, condom use was more frequent with casual or commercial partners. Those who traded sex for money were less likely to be white Anglo or regular heroin users, and more likely to be regular crack users and alcoholic, have fathers who were drug or alcohol users, and perceive themselves as at-risk for contracting HIV and other sexually transmitted diseases.

description: We analyze general convergence properties of the Taylor expansion of observables to finite chemical potential in the framework of an effective 2+1 flavor Polyakov-quark-meson model. To compute the required higher order coefficients a novel technique based on algorithmic differentiation has been developed. Results for thermodynamic observables as well as the phase structure obtained through the series expansion up to 24th order are compared to the full model solution at finite chemical potential. The available higher order coefficients also allow for resummations, e.g. Pade series, which improve the convergence behavior. In view of our results we discuss the prospects for locating the QCD phase boundary and a possible critical endpoint with the Taylor expansion method.

description: This study examines the financial technology (or FinTech) credit platform literature published between 2017 and 2022, as collected from the Scopus database. It follows the categorization of Imerman and Fabozzi, Lee and Shin, and Reiners for FinTech and credit platforms. In addition, this study follows the perceived risk classifications of Abramova and Bohme, Featherman and Pavlou, and Ryu. The significance of this study stems from the need for a comprehensive analysis of all FinTech credit platform types, their problems, and the gaps in the existing literature to guide future research. Therefore, this study focuses on the vertical business models of FinTech and its credit platforms. In doing so, it clarifies the relationships between perceived risk facets that could impact FinTech credit platforms, identifies the causes of perceived risks, and compiles all proposed solutions to mitigate perceived risks from previous studies. In addition, the format and methodology of this study adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) declaration, which includes four phases and a checklist of twenty-seven items. Using thirteen keywords, 1147 publications were collected from the Scopus database, from which 123 papers fitted the PRISMA procedure employed for this study. This survey determined peer-to-peer lending and crowdfunding platforms to be the most popular platforms. Financial, operational, legal, security, and overall risks were determined to be the five most prominent aspects of perceived risk. The default risk factor appeared as the largest contributor to financial and other interrelated hazards among the risk factors. Thus, this work makes several significant contributions. It aids regulators in formulating laws and policies to manage, monitor, and control the FinTech industry. It provides useful insight to lenders and investors, particularly in assisting them to obtain clearer feasibility for investment into such platforms by defining potential perceived risks and their factors. In conclusion, it guides scholars in the pursuit of future investigations.
Spin-precession-assisted supercurrent in a superconducting quantum point contact coupled to a single-molecule magnet

description: The supercurrent of a quantum point contact coupled to a nanomagnet strongly depends on the dynamics of the nanomagnet's spin. We employ a fully microscopic model to calculate the transport properties of a junction coupled to a spin whose dynamics is modeled as Larmor precession brought about by an external magnetic field and find that the dynamics affects the charge and spin currents by inducing transitions between the continuum states below the superconducting gap edge and the Andreev levels. This redistribution of the quasiparticles leads to a non-equilibrium population of the Andreev levels and an enhancement of the supercurrent which is visible as a modified current-phase relation as well as a non-monotonous critical current as function of temperature. The non-monotonous behavior is accompanied by a corresponding change in spin-transfer torques acting on the precessing spin and leads to the possibility of using temperature as a means to tune the back-action on the spin.

description: Arsenic (As) toxicity causes senous health problems in humans. Selenium (Se), an important micronutrient and antioxidant acts as an antagonist of arsenic (As). Selenium is seriously deficient in Southeast Asian soils, but has good levels in Saskatchewan (SK) soils. We evaluated two kinds of Se manipulated diets in counteracting As toxicity in rats evident through liver damage (peroxidative stress), immunotoxicity (antibody response), depleted glutathione levels, as well as increased As residues in tissue (liver, kidney, whole blood) and excreta (urine, feces). For both studies, higher Se diets (rodent chow and lentil-based feed) resulted in higher glutathione (GSH), lower lipid peroxidative damage, recovered antibody response, higher fecal As excretion and lower renal As residues. These findings support the hypothesis that As toxicity is decreased through naturally high Se lentil diets as well as Se fortified rodent chow by reducing the As induced damage and eliminating As from the body.
Analyzing Cosmic Bubble Collisions

description: We develop a set of controlled, analytic approximations to study the effects of bubble collisions on cosmology. We expand the initial perturbation to the inflaton field caused by the collision in a general power series, and determine its time evolution during inflation in terms of the coefficients in the expansion. In models where the observer's bubble undergoes sufficient slow-roll inflation to solve the flatness problem, in the thin wall limit only one coefficient in the expansion is relevant to observational cosmology, allowing nearly model-independent predictions. We discuss two approaches to determining the initial perturbation to the inflaton and the implications for the sign of the effect (a hot or cold spot on the Cosmic Microwave Background temperature map). Lastly, we analyze the effects of collisions with thick-wall bubbles, i.e. away from the thin-wall limit.

Conceptually delineating time and money: construal level theory and the case of charitable contributions

description: This thesis contributes to the marketing and psychology literatures by identifying a critical distinction in the perceptual nature that time and money each assumes using Construal Level Theory (Trope and Liberman 2003). With time being more psychologically distant and thus abstract than money, the results of seven experiments demonstrate that merely drawing individuals' attention to time, or to money, can significantly alter one's mindset, intentions and behaviors. After first examining how time and money differ on a construal level, I examine how the psychological construal of each resource affects intentions to make charitable contributions of time and money as a means of delineating these two concepts. This thesis begins by presenting an overview of the literature on Construal Level Theory (CLT) and the concepts of time and money (Chapter 1), followed by a set of seven experiments. Chapter 2 examines to what extent time (vs. money) is construed abstractly (vs. concretely; Studies 1-3). Next, the match between time (vs. money) and abstract (vs. concrete) construal level is examined as an individual difference (Study 4) and within the context of a charitable message (Study 5 and 6). Thus, Chapter 3 examines to what extent individual differences in construal predict contributions of time (vs. money; Study 4), and whether construal of a charitable message as abstract (vs. concrete) and a charitable request of time (vs. money) interact to predict consumers' intentions to contribute (Study 5) and contribution behaviors (Study 6). Finally, I examine the effect of reconstruing money in more abstract (vs. concrete) terms on charitable donation intentions (Study 7). I discuss theoretical and practical implications as well as future considerations in Chapter 4. This research contributes to the charitable-giving literature by suggesting that matching based on construal level, operationalized as both an individual difference (i.e., construal preference) and a tactical approach (i.e., matching message construal with the type of ask), can improve contribution outcomes. It also distinguishes specificity of the cause from identifying the "victim" and suggests marketing managers can identify prospects and develop marketing materials in a manner consistent with their desired time-raising or fundraising objectives. Finally, the current research proposes a mechanism for these effects. Specifically, that a match between construal level and the type of resource requested creates greater processing fluency, which increases consumer perceptions of the campaign's likelihood of success and, in turn, enhances contribution intentions.
Is H+3 cooling ever important in primordial gas?

description: Studies of the formation of metal-free Population III stars usually focus primarily on the role played by H2 cooling, on account of its large chemical abundance relative to other possible molecular or ionic coolants. However, while H2 is generally the most important coolant at low gas densities, it is not an effective coolant at high gas densities, owing to the low critical density at which it reaches local thermodynamic equilibrium (LTE) and to the large opacities that develop in its emission lines. It is therefore possible that emission from other chemical species may play an important role in cooling high-density primordial gas. A particularly interesting candidate is the H+3 molecular ion. This ion has an LTE cooling rate that is roughly a billion times larger than that of H2, and unlike other primordial molecular ions such as H +2 or HeH+, it is not easily removed from the gas by collisions with H or H2. It is already known to be an important coolant in at least one astrophysical context – the upper atmospheres of gas giants – but its role in the cooling of primordial gas has received little previous study. In this paper, we investigate the potential importance of H+3 cooling in primordial gas using a newly developed H+3 cooling function and the most detailed model of primordial chemistry published to date. We show that although H+3 is, in most circumstances, the third most important coolant in dense primordial gas (after H2 and HD), it is nevertheless unimportant, as it contributes no more than a few per cent of the total cooling. We also show that in gas irradiated by a sufficiently strong flux of cosmic rays or X-rays, H+3 can become the dominant coolant in the gas, although the size of the flux required renders this scenario unlikely to occur.
