description: Given documented variation in pre-migration and migration-related experiences, Cuban immigrants in the U.S. who arrived during or subsequent to 1980 may be disadvantaged in mental health and psychosocial adjustment relative to earlier arrivals. Using wave 1 of the Physical Challenge and Health study, we compare earlier and later arriving immigrants in levels of depression, anxiety, and self-esteem and test whether adversity and social support, acculturation-related factors, or pre-migration conditions account for any differences observed among a sample of adults living in South Florida (N=191). Bivariate analyses reveal that later arrivals are relatively disadvantaged in anxiety and self-esteem and marginally so in depression. While later arrivals do not report more adversity in the U.S., they have lower levels of family support to cope with any adversity experienced. Later arrivals are also less likely to interview in English or to have a strong American identity, and they were more likely to have arrived as adults. Relative disadvantages in anxiety and self-esteem are best explained by indicators of acculturation and family support. Policies and programs that address acculturation difficulties and increase family support could improve the health and adjustment of these and similar immigrants.

description: In this paper we present a hierarchical data analysis pipeline for all-sky searches of continuous gravitational wave signals, like those emitted by spinning neutron stars asymmetric with respect to the rotation axis, with unknown position, rotational frequency and spin-down. The core of the pipeline is an incoherent step based on a particularly efficient implementation of the Hough transform, that we call frequency-Hough, that maps the data time-frequency plane to the source frequency/spin-down plane for each fixed direction in the sky. Theoretical ROCs and sensitivity curves are computed and the dependency on various thresholds is discussed. A comparison of the sensitivity loss with respect to an "optimal" method is also presented. Several other novelties, with respect to other wide-parameter analysis pipelines, are also outlined. They concern, in particular, the construction of the grid in the parameter space, with over-resolution in frequency and parameter refinement, candidate selection and various data cleaning steps which are introduced to improve search sensitivity and rejection of false candidates.

description: A recent CMS search for the right handed gauge boson $W_R$ reports an interesting deviation from the Standard Model. The search has been conducted in the $eejj$ channel and has shown a 2.8$σ$ excess around $m_{eejj} \sim 2$ TeV. In this work, we explain the reported CMS excess with R-parity violating supersymmetry (SUSY). We consider resonant selectron and sneutrino production, followed by the three body decays of the neutralino and chargino via an $\mathcal{R}-$parity violating coupling. We fit the excess for slepton masses around 2 TeV. The scenario can further be tested in neutrinoless double beta decay ($0νββ$) experiments. GERDA Phase-II will probe a significant portion of the good-fit parameter space.

Understanding community context and adult health changes in China: Development of an urbanicity scale

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: The classification of places as either urban or rural is typically based on an absolute threshold of population and/or population density. However, conceptual definitions of urbanization and urbanicity encompass dimensions beyond solely population size and population density. Multiple important distinguishing urban characteristics beyond population size have been described. The crude classification of places as urban or rural coupled with infrequent updates to this information create a measure that is prone to misclassification error. An improved measure of urbanicity would draw information from the domains that characterize urban and rural places, would be sensitive to changes over time, and would represent gradations on the continuum from rural to urban environments. The goal of the current study was to develop such a scale from existing data, test whether the scale was reliable and valid, and assess whether it provided information beyond what could be determined from the traditional urban/rural dichotomous variable. We utilized established scaling procedures from the psychometric literature to construct and evaluate a multicomponent scale to measure urban features on a continuum in China. We also provided an example of its potential contribution to health research by examining its relationship with the adult body mass index (BMI). Because the scale was constructed and tested using established scaling procedures and using a wide array of variables, it represents an improvement over previous attempts at such a scale and will provide a reliable and valid measurement tool for researchers in this arena. The scale was developed to predict the incidence of overweight/obesity populations in China, but it promises to be most useful for other economic, demographic, social welfare, and health outcomes.

What do physicians gain (and lose) with experience? Qualitative results from a cross-national study of diabetes

description: An empirical puzzle has emerged over the last several decades of research on variation in clinical decision making involving mixed effects of physician experience. There is some evidence that physicians with greater experience may provide poorer quality care than their less experienced counterparts, as captured by various quality assurance measures. Physician experience is traditionally narrowly defined as years in practice or age, and there is a need for investigation into precisely what happens to physicians as they gain experience, including the reasoning and clinical skills acquired over time and the ways in which physicians consciously implement those skills into their work. In this study, we are concerned with 1) how physicians conceptualize and describe the meaning of their clinical experience, and 2) how they use their experience in clinical practice. To address these questions, we analyzed qualitative data drawn from in-depth interviews with physicians from the United States, United Kingdom, and Germany as a part of a larger factorial experiment of medical decision making for diabetes. Our results show that common measures of physician experience do not fully capture the skills physicians acquire over time or how they implement those skills in their clinical work. We found that what physicians actually gain over time is complex social, behavioral and intuitive wisdom as well as the ability to compare the present day patient against similar past patients. These active cognitive reasoning processes are essential components of a forward-looking research agenda in the area of physician experience and decision making. Guideline-based outcome measures, accompanied by underdeveloped age- and years-based definitions of experience, may prematurely conclude that more experienced physicians are providing deficient care while overlooking the ways in which they are providing more and better care than their less experienced counterparts.

description: This study explores community members’ perspectives regarding the relationship between neighborhood characteristics and adolescent sexual behaviors in two rural, African American communities. The data were collected as part of a community needs assessment to inform the development of HIV prevention interventions in two contiguous counties in northeastern North Carolina, USA. We conducted eleven focus groups with three population groups: adolescents and young adults aged 16–24 (N=38), adults over age 25 (N=42), and formerly incarcerated individuals (N=13). All focus groups were audio-recorded, transcribed and analyzed using a grounded theory approach to content analysis and a constant comparison method. Six major themes emerged from the discussions linking neighborhood context and adolescents sexual behavior: the overwhelming absence of recreational options for community members; lack of diverse leisure-time activities for adolescents; lack of recreational options for adolescents who are dating; adolescent access to inappropriate leisure time activities that promote multiple risk behaviors; limited safe environments for socializing; and cost-barriers to recreational activities for adolescents. In addition, lack of adequate parental supervision of adolescents’ time alone and with friends of the opposite sex, as well as ineffective community monitoring of adolescent social activities, were thought to create situations that promoted sexual and other risk behaviors. These findings allowed us to develop a conceptual model linking neighborhood structural and social organization factors to adolescent sexual behaviors and provided insights for developed interventions tailored to the local socioeconomic realities.

description: If $Γ$ is any nonuniform lattice in the group ${\rm PU}(2,1)$, let $\overlineΓ$ be the quotient of $Γ$ obtained by filling the cusps of $Γ$ (i.e. killing the center of parabolic subgroups). Assuming that such a lattice $Γ$ has positive first Betti number, we prove that for any sufficiently deep subgroup of finite index $Γ_{1} < Γ$, the group $\overline{Γ_{1}}$ is noncoherent. The proof relies on previous work of M. Kapovich as well as of C. Hummel and V. Schroeder.

description: Южное Предуралье рассматривается как экотон. Лесные экосистемы Южного Предуралья, в том числе и Оренбургской области, сильно отличаются от таковых в европейской части РФ, в Сибири, на Дальнем востоке и пр. В период отсутствия агроценозов основной фон растительного покрова лесостепной зоны составляли сообщества луговой степи, чередующиеся с участками лиственных лесов. Для ряда видов древесно-кустарниковых растений лесных фитоценозов по территории области проходят границы ареалов. На данной территории систематически наблюдаются случаи загрязнения атмосферы, почвы, воды водоемов и подземных вод. Экологическая обстановка на территории Оренбургской области крайне неблагоприятная, что обусловлено повышенным содержанием тяжелых металлов в горных породах и грунтовых водах, высокой техногенной нагрузкой. В настоящее время сформировалась проблема техногенного загрязнения земель, в результате чего увеличиваются площади территорий, загрязненных отходами промышленных предприятий, нефтью и нефтепродуктами, тяжелыми металлами, пестицидами и другими токсичными веществами. Это определяет формирование экстремальных и критических условий для произрастания деревьев и кустарников, для успешного существования лесных экосистем. Лесные насаждения в значительной степени ослаблены, находятся в стрессовом состоянии и характеризуются пониженной устойчивостью и способностью к саморегуляции. В настоящее время в лесах региона в фоновом режиме присутствуют различные листои хвоегрызущие филлофаги. Уникальность Южного Предуралья в границах Оренбургской области состоит в том, что в условиях негативного воздействия на природные комплексы со стороны промышленности, добычи природных ископаемых, радиации (последствия Тоцкого ядерного взрыва), перевода естественных ландшафтов в агроландшафты, но и в том, что данная территория находится на границах полупустыни и степи, степи и лесостепи. Лесные насаждения в этих условиях характеризуются высокой частотой вспышек массового размножения вредителей.

description: We demonstrate successful "dry" refrigeration of quantum fluids down to $T=0.16$\,mK by using copper nuclear demagnetization stage that is pre-cooled by a pulse-tube-based dilution refrigerator. This type of refrigeration delivers a flexible and simple sub-mK solution to a variety of needs including experiments with superfluid $^3$He. Our central design principle was to eliminate relative vibrations between the high-field magnet and the nuclear refrigeration stage, which resulted in the minimum heat leak of $Q=4.4$\,nW obtained in field of 35\,mT. For thermometry, we employed a quartz tuning fork immersed into liquid $^3$He. We show that the fork oscillator can be considered as self-calibrating in superfluid $^3$He at the crossover point from hydrodynamic into ballistic quasiparticle regime.

description: The high prevalence of child under-nutrition remains a profound challenge in the developing world. Maternal autonomy was examined as a determinant of breast feeding and infant growth in children 3 to 5 months of age. Cross-sectional baseline data on 600 mother-infant pairs were collected in 60 villages in rural Andhra Pradesh, India. The mothers were enrolled in a longitudinal randomized behavioral intervention trial. In addition to anthropometric and demographic measures, an autonomy questionnaire was administered to measure different dimensions of autonomy (e.g. decision-making, freedom of movement, financial autonomy, and acceptance of domestic violence). We conducted confirmatory factor analysis on maternal autonomy items and regression analyses on infant breast feeding and growth after adjusting for socioeconomic and demographic variables, and accounting for infant birth weight, infant morbidity, and maternal nutritional status. Results indicated that mothers with higher financial autonomy were more likely to breastfeed 3–5 month old infants. Mothers with higher participation in decision-making in households had infants that were less underweight and less wasted. These results suggest that improving maternal financial and decision-making autonomy could have a positive impact on infant feeding and growth outcomes.

They argue further that this solves the problem of making sense of probabilities within Everettian quantum theory, even though the theory itself is deterministic. We note some problems with these arguments.

description: Data fusion is the combination of the results of independent searches on a document collection into one single output result set. It has been shown in the past that this can greatly improve retrieval effectiveness over that of the individual results. This paper presents probFuse, a probabilistic approach to data fusion. ProbFuse assumes that the performance of the individual input systems on a number of training queries is indicative of their future performance. The fused result set is based on probabilities of relevance calculated during this training process. Retrieval experiments using data from the TREC ad hoc collection demonstrate that probFuse achieves results superior to that of the popular CombMNZ fusion algorithm.

description: Spiking Neural Networks (SNNs) offer a promising alternative to Artificial Neural Networks (ANNs) for deep learning applications, particularly in resource-constrained systems. This is largely due to their inherent sparsity, influenced by factors such as the input dataset, the length of the spike train, and the network topology. While a few prior works have demonstrated the advantages of incorporating sparsity into the hardware design, especially in terms of reducing energy consumption, the impact on hardware resources has not yet been explored. This is where design space exploration (DSE) becomes crucial, as it allows for the optimization of hardware performance by tailoring both the hardware and model parameters to suit specific application needs. However, DSE can be extremely challenging given the potentially large design space and the interplay of hardware architecture design choices and application-specific model parameters. In this paper, we propose a flexible hardware design that leverages the sparsity of SNNs to identify highly efficient, application-specific accelerator designs. We develop a high-level, cycle-accurate simulation framework for this hardware and demonstrate the framework's benefits in enabling detailed and fine-grained exploration of SNN design choices, such as the layer-wise logical-to-hardware ratio (LHR). Our experimental results show that our design can (i) achieve up to $76\%$ reduction in hardware resources and (ii) deliver a speed increase of up to $31.25\times$, while requiring $27\%$ fewer hardware resources compared to sparsity-oblivious designs. We further showcase the robustness of our framework by varying spike train lengths with different neuron population sizes to find the optimal trade-off points between accuracy and hardware latency.

description: We study analytically and numerically a bistable reaction-diffusion equation on an arbitrary finite network. We prove that stable fixed points (multi-fronts) exist for any configuration as long as the diffusion is small. We also study fold bifurcations leading to depinning and give a simple depinning criterion. These results are confirmed by using continuation techniques from bifurcation theory and by solving the time dependent problem near the treshold. A qualitative comparison principle is proved and verified for time dependent solutions, and for some related models.
Quantum critical behavior of the quantum Ising model on fractal lattices

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: I study the properties of the quantum critical point of the transverse-field quantum Ising model on various fractal lattices such as the Sierpiński carpet, Sierpiński gasket, and Sierpiński tetrahedron. Using a continuous-time quantum Monte Carlo simulation method and the finite-size scaling analysis, I identify the quantum critical point and investigate its scaling properties. Among others, I calculate the dynamic critical exponent and find that it is greater than one for all three structures. The fact that it deviates from one is a direct consequence of the fractal structures not being integer-dimensional regular lattices. Other critical exponents are also calculated. The exponents are different from those of the classical critical point, and satisfy the quantum scaling relation, thus confirming that I have indeed found the quantum critical point. I find that the Sierpiński tetrahedron, of which the dimension is exactly two, belongs to a different universality class than that of the two-dimensional square lattice. I conclude that the critical exponents depend on more details of the structure than just the dimension and the symmetry.

description: Quantum codes excel at correcting local noise but fail to correct leakage faults that excite qubits to states outside the computational space. Aliferis and Terhal have shown that an accuracy threshold exists for leakage faults using gadgets called leakage reduction units (LRUs). However, these gadgets reduce the accuracy threshold and can increase overhead and experimental complexity, and these costs have not been thoroughly understood. Our work explores a variety of techniques for leakage-resilient, fault-tolerant error correction in the context of topological codes. Our contributions are threefold. First, we develop a leakage model that differs in critical details from earlier models. Second, we use Monte-Carlo simulations to survey several syndrome extraction circuits. Third, given the capability to perform three-outcome measurements, we present a dramatically improved syndrome processing algorithm. Our simulation results show that simple circuits with one extra CNOT per qubit and no additional ancillas reduce the accuracy threshold by less than a factor of 4 when leakage and depolarizing noise rates are comparable. This becomes a factor of 2 when the decoder uses 3-outcome measurements. Finally, when the physical error rate is less than 2 x 10^-4, placing LRUs after every gate may achieve the lowest logical error rates of all of the circuits we considered. We expect the closely related planar and rotated codes to exhibit the same accuracy thresholds and that the ideas may generalize naturally to other topological codes.

description: We interpret the close link between the critical points of Mather's barrier functions and minimal homoclinic orbits with respect to the Aubry sets on $\mathbb{T}^n$. We also prove a critical point theorem for barrier functions, and the existence of such homoclinic orbits on $\mathbb{T}^2$ as an application.

description: "In this paper, I consider some of the alternative ways of being a man that have emerged in Papua New Guinea. Specifically, I discuss the ways that some forms of Christianity are promoting more caring, responsible and non-violent forms of masculinity in Papua New Guinea. Considering Christianity’s huge influence there, together with the need to ground interventions in the local context, a good understanding of the nature of Papua New Guinean forms of Christianity, and how they impact on gender, is necessary for designing effective primary prevention initiatives. Though my focus here is on the specific case of Papua New Guinea, which I know best, many of my observations are almost certainly applicable to other countries in Melanesia and the wider Pacific, where Christianity is also highly influential..." - page 3
Warten auf Ersch_Computationally feasible bounds for the free energy of nonequilibrium steady states, applied to simple models of heat conduction

description: In this paper, we study computationally feasible bounds for relative free energies between two many-particle systems. Specifically, we consider systems out of equilibrium that admit a nonequilibrium steady state that is reached asymptotically in the long-time limit. The bounds that we suggest are based on the well-known Bogoliubov inequality and variants of Gibbs' and Donsker–Varadhan variational principles. As a general paradigm, we consider systems of oscillators coupled to heat baths at different temperatures. For such systems, we define the free energy of the system relative to any given reference system in terms of the Kullback–Leibler divergence between steady states. By employing a two-sided Bogoliubov inequality and a mean-variance approximation of the free energy (or cumulant generating function), we can efficiently estimate the free energy cost needed in passing from the reference system to the system out of equilibrium (characterised by a temperature gradient). A specific test case to validate our bounds are harmonic oscillator chains with ends that are coupled to Langevin thermostats at different temperatures; such a system is simple enough to allow for analytic calculations and general enough to be used as a prototype to estimate, e.g. heat fluxes or interface effects in a larger class of nonequilibrium particle systems.

description: In bacteria, production of aberrant RNAs and transcription of foreign genes, including those on phages, are readily terminated by a hexameric ATPase, Rho. However, to make necessary transcripts, particularly during stress, bacteria depend on mechanisms to temper Rho activity. Similarly, phages have evolved diverse Rho-inhibitory mechanisms to enable the expression of their own genomes. In recent years, the structural bases of many such anti-termination mechanisms have been elucidated.
A Radio and X-ray Study of the Merging Cluster A2319

description: A2319 is a massive, merging galaxy cluster with a previously detected radio halo that roughly follows the X-ray emitting gas. We present the results from recent observations of A2319 at 20 cm with the Jansky Very Large Array (VLA) and a re-analysis of the X-ray observations from XMM-Newton, to investigate the interactions between the thermal and nonthermal components of the ICM . We confirm previous reports of an X-ray cold front, and report on the discovery of a distinct core to the radio halo, 800 kpc in extent, that is strikingly similar in morphology to the X-ray emission, and drops sharply in brightness at the cold front. We detect additional radio emission trailing off from the core, which blends smoothly into the 2 Mpc halo detected with the Green Bank Telescope (GBT; Farnsworth et al., 2013). We speculate on the possible mechanisms for such a two-component radio halo, with sloshing playing a dominant role in the core. By directly comparing the X-ray and radio emission, we find that a hadronic origin for the cosmic ray electrons responsible for the radio halo would require a magnetic field and/or cosmic ray proton distribution that increases with radial distance from the cluster center, and is therefore disfavored.

Mechanisms of the Effect of Individual Education on Pro-European Dispositions

description: A burgeoning empirical literature on attitudes towards Europe shows that highly educated individuals are more likely to hold pro-European dispositions than non-highly educated individuals. The literature provides structural and cultural accounts for this relationship. The structural account highlights that formal education contributes to earning higher incomes and attaining an upper-class occupation, which are conducive to pro-European dispositions. The cultural account instead highlights that formal education instils universalist and non-traditionalist values in individuals, which are conducive to pro-European dispositions. This is the first article to assess the relative predictive power of these two approaches. Using structural equation models, Rounds 8–10 of the European Social Survey and three indicators of pro-European dispositions, this article examines whether socio-economic location measured by income and upper-class occupation or commitment to human values measured by universalism and traditionalism mediates this association. All in all, the structural approach receives stronger support than the cultural one.
Stellar multiplicity aspect in the chemo-dynamic Milky Way disk model
Creators: name: Kseniia, Sysoliatina
Publisher: name: Zenodo
Year: 2022

description: The Just-Jahreiß (JJ) model describes an axisymmetric Milky Way (MW) disk and is a tool for stellar population synthesis. It includes exponential thin and thick disks, atomic and molecular gas layers, spherical stellar halo, and cored isothermal dark matter sphere. The overall thin-disk thickness is independent of radius, and the radial variation of the thin-disk SFR reflects the inside-out disk growth. A smooth power-law star formation rate (SFR) continuum can be modified by an arbitrary number of Gaussian peaks consisting of dynamically hot stars, thus, representing gas infall episodes. For the stellar population synthesis, the JJ model is complemented by three alternative isochrone sets – PARSEC, MIST, and BaSTI.
 Up to now, the JJ model relies only on single-star evolution models, but the lack of binaries reveals itself when the modeled and realistic observed color-magnitude diagrams (CMD) are compared. As CMD comparison is often used to optimize the model parameters, it is necessary to account for binary stellar evolution in the future.

Subjects: subject: International Development

subject: Africa

description: Globalization has transformed the entire world into a borderless entity, making it very difficult to separate domestic policies from foreign ones. The interdependency of economies has made African countries more vulnerable to any given policy error or economic shocks in a foreign country. Domestic policy decisions have global repercussions. Besides, the unsustainable production and consumption systems (including greenhouse emissions associated with industrialization and urbanization) in the largest economies of the world unequivocally contribute to the rising impact of climate change in Africa – the continent that contributed to climate change the least, yet has the weakest capacity to manage its impacts. How does this dynamically changing development context affect the implementation of SDGs in Africa? What are the emerging opportunities and challenges associated with the implementation of SDGs in Africa? What specific actions should Africa and the rest of the world take to ensure the objective of ‘leaving no one behind’ in Africa by 2030 is realized? These are some of the questions this paper will address. However, it is first important to know: why are the SDGs important to Africa?
