description: In the urge of designing noble metal‐free and sustainable electrocatalysts for oxygen evolution reaction (OER), herein, a mineral Digenite Cu9S5 has been prepared from a molecular copper(I) precursor, [{(PyHS)2CuI(PyHS)}2](OTf)2 (1), and utilized as an anode material in electrocatalytic OER for the first time. A hot injection of 1 yielded a pure phase and highly crystalline Cu9S5, which was then electrophoretically deposited (EPD) on a highly conducting nickel foam (NF) substrate. When assessed as an electrode for OER, the Cu9S5/NF displayed an overpotential of merely 298±3 mV at a current density of 10 mA cm−2 in alkaline media. The overpotential recorded here supersedes the value obtained for the best reported Cu‐based as well as the benchmark precious‐metal‐based RuO2 and IrO2 electrocatalysts. In addition, the choronoamperometric OER indicated the superior stability of Cu9S5/NF, rendering its suitability as the sustainable anode material for practical feasibility. The excellent catalytic activity of Cu9S5 can be attributed to the formation of a crystalline CuO overlayer on the conductive Cu9S5 that behaves as active species to facilitate OER. This study delivers a distinct molecular precursor approach to produce highly active copper‐based catalysts that could be used as an efficient and durable OER electro(pre)catalysts relying on non‐precious metals.

description: We consider error suppression schemes in which quantum information is encoded into the ground subspace of a Hamiltonian comprising a sum of commuting terms. Since such Hamiltonians are gapped they are considered natural candidates for protection of quantum information and topological or adiabatic quantum computation. However, we prove that they cannot be used to this end in the 2-local case. By making the favorable assumption that the gap is infinite we show that single-site perturbations can generate a degeneracy splitting in the ground subspace of this type of Hamiltonians which is of the same order as the magnitude of the perturbation, and is independent of the number of interacting sites and their Hilbert space dimensions, just as in the absence of the protecting Hamiltonian. This splitting results in decoherence of the ground subspace, and we demonstrate that for natural noise models the coherence time is proportional to the inverse of the degeneracy splitting. Our proof involves a new version of the no-hiding theorem which shows that quantum information cannot be approximately hidden in the correlations between two quantum systems, and should be of independent interest. The main reason that 2-local commuting Hamiltonians cannot be used for quantum error suppression is that their ground subspaces have only short-range (two-body) entanglement.

description: In this work, we first predict the mass spectra of the $Ω_{c}^{(*)}{D}_s^{(*)}$-type doubly charmed molecular pentaquark candidates, where the one-boson-exchange model is adopted by considering both the $S$-$D$ wave mixing effect and the coupled channel effect. Our findings indicate that the $Ω_{c}{D}_s^*$ state with $J^P={1}/{2}^{-}$, the $Ω_{c}^*{D}_s^*$ state with $J^P={1}/{2}^{-}$, and the $Ω_{c}^*{D}_s^*$ state with $J^P={3}/{2}^{-}$ can be considered as the most promising doubly charmed molecular pentaquark candidates, and the $Ω_{c}{D}_s$ state with $J^P={1}/{2}^{-}$, the $Ω_{c}^*{D}_s$ state with $J^P={3}/{2}^{-}$, and the $Ω_{c}{D}_s^*$ state with $J^P={3}/{2}^{-}$ are the possible doubly charmed molecular pentaquark candidates. Furthermore, we further explore the radiative decays and the magnetic moments of the most promising doubly charmed molecular pentaquark candidates in the constituent quark model. As a crucial aspect of spectroscopy, the information of the radiative decays and the magnetic moments can provide the valuable clues to reflect their inner structures. With the accumulation of higher statistical data at the Large Hadron Collider, we propose that the LHCb Collaboration should focus on the problem of searching for these predicted doubly charmed molecular pentaquark candidates containing most strange quarks in the coming years.

Distrustful quantum steering

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Quantum steering is an asymmetric form of quantum nonlocality where one can trust the measurements of one of the parties. In this work, inspired by practical considerations we investigate the scenario if one can not fully trust their measurement devices but only up to some precision. We first find the effect of such an imprecision on standard device-dependent quantum tomography. We then utilise this result to compute the variation in the local bound of any general steering inequality depending on the amount of trust one puts in one of the party's measurement devices. This is particularly important as we show that even a small distrust on Alice might cause the parties to observe steerability even if the quantum state is unsteerable. Furthermore, this effect becomes more relevant when observing higher dimensional quantum steering.

description: When the supersymmetry breaking sector is a fluid background, Lorentz invariance is broken spontaneously. The super-Higgs mechanism leads to a gravitino Lagrangian with Lorentz symmetry violating terms. We analyse the resulting field equations and constraints. We identify the physical spin 3/2 and spin 1/2 helicity states, derive their equations of motion and construct the propagator. The violation of Lorentz symmetry implies that the longitudinal mode has a non-relativistic dispersion relation, whose speed is lower than the speed of light. We briefly comment on possible implications to gravitino cosmology and phenomenology.

description: How complex corporations with multidimensional structures create value is a topic of enduring interest and relevance. What is missing from the published literature are in-depth examinations of the nuances found in complex corporate structures, their vertical layers, and particularly with respect to multi-level headquarters (HQ) structures. To fill this gap, this dissertation presents the analysis of a multiple case study in the Massy Group, a large multidivisional, and multinational corporation that operates in the Caribbean, Latin America, and the United States. My research focuses specifically on how corporate parents seek to create value, particularly in relation to how organizational integration is sought in complex corporate structures. Through in-depth interviews with a total of 55 Massy Group insiders as informants across five strategic initiatives that involved different kinds of cross-unit collaboration, I sought insight into two research questions: 1) What is the role of multiple HQ levels in supporting cross-unit collaboration? and 2) How do multiple HQ levels deploy integrative devices to support cross-unit collaboration? In my research, I concluded that both management and oversight at multiple HQ levels are crucial for enabling cross-unit collaboration and elaborated on how the theoretical concepts of integrative devices can manifest as HQ roles. More specifically, the study highlights how the use of authority, communication, and cross-unit structure are important integrative devices that support collaboration within this organizational context. Overall, the findings of this research contribute to a better understanding of the roles and mechanisms through which multiple HQ levels can facilitate cross-unit collaboration in large, diversified multinational firms.

description: While the concept of transnationalism has gained widespread popularity among scholars as a way to describe immigrants’ long-term maintenance of cross-border ties to their origin communities, critics have argued that the overall proportion of immigrants who engage in transnational behavior is low and that, as a result, transnationalism has little sustained effect on the process of immigrant adaptation and assimilation. In this paper, we argue that a key shortcoming in the current empirical debate on transnationalism is the lack of data on the social networks that connect migrants to each other and to non-migrants in communities of origin. To address this shortcoming, our analysis uses unique bi-national data on the social network connecting an immigrant sending community in Guanajuato, Mexico, to two destination areas in the United States. We test for the effect of respondents’ positions in cross-border networks on their migration intentions and attitudes towards the United States using data on the opinions of their peers, their participation in cross border and local communication networks, and their structural position in the network. The results indicate qualified empirical support for a network-based model of transnationalism; in the U.S. sample we find evidence of network clustering consistent with peer effects, while in the Mexican sample we find evidence of the importance of cross-border communication with friends.
An economic evaluation of schizophrenia–1991

description: In 1991, the costs for schizophrenia, which has a lifetime prevalence of 1.5% among adult Americans, totaled $65 billion. Costs were broken down into their direct and indirect components. Direct costs, which totaled $19 billion dollars, consisted of treatment-related expenditures such as those for inpatients and outpatients, as well as nontreatment-related expenditures such as those for the criminal justice system used by individuals with schizophrenia. The direct costs were fairly similar to those of other recent estimates of the cost of schizophrenia. Indirect costs, which were $46 billion dollars, included the lost productivity of both wage earners ($24 billion) and homemakers ($4.5 billion), individuals who were in institutions ($4.5 billion) or who had committed suicide ($7 billion), and caregivers who took care of schizophrenic family members ($7 billion). Our method for calculating the indirect costs was slightly different than methods used in prior studies, which may account for our estimates being higher. The method for determining each expenditure is provided, and the implications of these staggering costs are discussed.
Small-scale Nonlinear Dynamics of K-mouflage Theories

description: We investigate the small-scale static configurations of K-mouflage models defined by a general function $K(χ)$ of the kinetic terms. The fifth force is screened by the nonlinear K-mouflage mechanism if $K'(χ)$ grows sufficiently fast for large negative $χ$. In the general non-spherically symmetric case, the fifth force is not aligned with the Newtonian force. For spherically symmetric static matter density profiles, the results depend on the potential function $W_{-}(y) = y K'(-y^2/2)$, which must be monotonically increasing to $+\infty$ for $y \geq 0$ to guarantee the existence of a single solution throughout space for any matter density profile. Small radial perturbations around these static profiles propagate as traveling waves with a velocity greater than the speed of light. Starting from vanishing initial conditions for the scalar field and for a time-dependent matter density corresponding to the formation of an overdensity, we numerically check that the scalar field converges to the static solution. If $W_{-}$ is bounded, for high-density objects there are no static solutions throughout space, but one can still define a static solution restricted to large radii. Our dynamical study shows that the scalar field relaxes to this static solution at large radii, whereas spatial gradients keep growing with time at smaller radii. If $W_{-}$ is not bounded but non-monotonic, there is an infinite number of discontinuous static solutions but they are not physical and these models are not theoretically sound. Such K-mouflage scenarios provide an example of theories that can appear viable at the cosmological level, for the cosmological background and perturbative analysis, while being meaningless at a nonlinear level for small-scale configurations. This shows the importance of small-scale nonlinear analysis of screening models.

description: Offspring of depressed parents are at increased risk for depressive and other disorders. We recently found that when depressed mothers reached full remission over 3 months of treatment, a significant improvement in the children’s disorders occurred. Since only a third of the mothers remitted, factors related to maternal remission rates, and thereby child outcomes, were important. This report examined the relationship of the presence of a father in the household to maternal depression remission and child outcomes.

description: Computing the state of a quantum mechanical many-body system composed of indistinguishable particles distributed over a multitude of modes is one of the paradigmatic test cases of computational complexity theory: Beyond well-understood quantum statistical effects, the coherent superposition of many-particle amplitudes rapidly overburdens classical computing devices - essentially by creating extremely complicated interference patterns, which also challenge experimental resolution. With the advent of controlled many-particle interference experiments, optical set-ups that can efficiently probe many-boson wave functions - baptised BosonSamplers - have therefore been proposed as efficient quantum simulators which outperform any classical computing device, and thereby challenge the extended Church-Turing thesis, one of the fundamental dogmas of computer science. However, as in all experimental quantum simulations of truly complex systems, there remains one crucial problem: How to certify that a given experimental measurement record is an unambiguous result of sampling bosons rather than fermions or distinguishable particles, or of uncontrolled noise? In this contribution, we describe a statistical signature of many-body quantum interference, which can be used as an experimental (and classically computable) benchmark for BosonSampling.

description: Self-propelled particles in anisotropic environments can exhibit a motility that depends on their orientation. This dependence is relevant for a plethora of living organisms but difficult to study in controlled environments. Here, we present a macroscopic system of self-propelled vibrated granular particles on a striated substrate that displays orientation-dependent motility. An extension of the active Brownian motion model involving orientation-dependent motility and inertial effects reproduces and explains our experimental observations. The model can be applied to general $n$-fold symmetric anisotropy and can be helpful for predictive optimization of the dynamics of active matter in complex environments.

description: Klinefelter, Turner, and fragile X syndromes are conditions defined by a genetic or chromosomal variant. The timing of diagnosis, tests employed, specialists involved, symptoms evident, and prognoses available vary considerably within and across these syndromes, but all three share in common a diagnosis verified through a molecular or cytogenetic test. The genetic or chromosomal variant identified designates a syndrome, even when symptoms associated with the particular syndrome are absent. This article analyzes interviews conducted with parents and grandparents of children with these syndromes from across the US to explore how they interpret a confirmed genetic diagnosis that is associated with a range of possible symptoms that may never be exhibited. Parents’ responses indicate that they see the genetic aspects of the syndrome as stable, permanent and authoritative. But they allow, and even embrace, uncertainty about the condition by focusing on variation between diagnosed siblings, the individuality of their diagnosed child, his or her accomplishments, and other positive aspects that go beyond the genetic diagnosis. Some families counter the genetic diagnosis by arguing that in the absence of symptoms, the syndrome does not exist. They use their own expertise to question the perceived certainty of the genetic diagnosis and to employ the diagnosis strategically. These multiple and often conflicting evaluations of the diagnostic label reveal the rich ways families make meaning of the authority attributed to genetic diagnosis.

description: In this work, we consider the spread of a 'civilisation' in an idealised homogeneous isotropic universe where all the planets of interest are habitable. Following a framework that goes beyond the usual idea of percolation, we investigate the behaviour of the number of colonised planets with time, and the total colonisation time for three types of universes. These include static, dark energy-dominated, and matter-dominated universes. For all these types of universes, we find a remarkable fit with the Logistic Growth Function for the number of colonised planets with time. This is in spite of the fact that for the matter- and dark-energy dominated universes, the space itself is expanding. For the total colonisation time, $T$, the case for a dark energy-dominated universe is marked with divergence beyond the linear regime characterised by small values of the Hubble parameter, $H$. Not all planets in a spherical section of this universe can be 'colonised' due to the presence of a shrinking Hubble sphere. In other words, the recession speeds of other planets go beyond the speed of light making them impossible to reach. On the other hand, for a matter-dominated universe, while there is an apparent horizon, the Hubble sphere is growing instead of shrinking. This leads to a finite total colonisation time that depends on the Hubble parameter characterising the universe; in particular, we find $T\sim H$ for small $H$ and $T\sim H^2$ for large $H$.

description: China has recently undergone rapid social and economic change. Increases in urbanization have led to equally rapid shifts toward more sedentary occupations through the acquisition of new technology and transitions away from a mostly agricultural economy. Our purpose was to utilize a detailed measure of urbanicity comprising 10 dimensions of urban services and infrastructure to examine its effects on the occupational physical activity patterns of Chinese adults. Longitudinal data were from individuals aged 18-55 from the years 1991-1997 of the China Health and Nutrition Survey (N = 4376 men and 4384 women). Logistic multilevel regression analyses indicated that men had 68% greater odds, and women had 51% greater odds, of light versus heavy occupational activity given the mean change in urbanization over the 6-year period. Further, simulations showed that light occupational activity increased linearly with increasing urbanization. After controlling for individual-level predictors, community-level urbanization explained 54% and 40% of the variance in occupational activity for men and women, respectively. This study provides empirical evidence of the reduction in intensity of occupational activity with modernization. It is likely that urbanization will continue unabated in China and this is liable to lead to further transitions in the labor market resulting in additional reductions in work-related activity. Because occupational activity remains the major source of energy expenditure for adults, unless alternative forms are widely adopted, the Chinese population is at risk of dramatic increases in the numbers of overweight and obese individuals.

Comparability work and the management of difference in research synthesis studies

description: The new imperative to be more methodologically inclusive has generated a burgeoning interest in synthesizing the findings of qualitative and quantitative studies, or mixed research synthesis. Yet, the very diversity seen to define the mixed research synthesis enterprise is also considered to defy it as it intensifies the problem of comparing the seemingly incomparable to enable the combination of the seemingly uncombinable. We propose here that the research synthesis enterprise, in general, and the mixed research synthesis enterprise, in particular, entail comparability work whereby reviewers impose similarity and difference on the studies to be reviewed. The very study diversity requiring management does not exist a priori but rather is itself an outcome of comparability work already done whereby judgments have been made about what constitutes methodological and topical diversity and uniformity. Conceiving the research synthesis process as defined by comparability work moves the backstage interpretive work of systematic review to center stage and, thereby, sets a new stage for addressing the methodological issues involved. These issues are explored by reference to the synthesis of empirical studies of antiretroviral adherence in HIV-positive women in the US.
The hot Neptune WASP-166 b with ESPRESSO. A blue-shifted tentative water signal constrains the presence of clouds
Creators: name: Lafarga, Marina
Publisher: name: Zenodo
Year: 2023

description: With high-resolution spectroscopy we can study exoplanet atmospheres and learn about their chemical composition, temperature profiles, and presence of clouds and winds, mainly in hot, giant planets. State-of-the-art instrumentation is pushing these studies towards smaller exoplanets. Of special interest are the few planets in the Neptune desert, a lack of Neptune-size planets in close orbits around their hosts. Studying these can provide insight to their planetary formation and evolution, and shed light on the origin of the desert. Here, we assess the presence of water in one such planet, the bloated super-Neptune WASP-166 b, which orbits an F9-type star in a short orbit of 5.4 days. Despite its close-in orbit, WASP-166 b preserved its atmosphere, making it a benchmark target for exoplanet atmosphere studies in the desert. We analyse two transits observed in the visible with ESPRESSO. We clean the spectra from the Earth's telluric absorption via principal component analysis, which is crucial to the search for water in exoplanets. We use a cross-correlation-to-likelihood mapping to simultaneously estimate limits on the abundance of water and the altitude of a cloud layer, which points towards a low water abundance and/or high clouds. We tentatively detect a water signal blue-shifted about 5 km/s from the planetary rest frame. This is the first time water has potentially been observed in the optical with ESPRESSO.

Here, two-mode correlated multiphoton bundle emission in a nondegenerate multiphoton Jaynes-Cummings model, which is comprised of a two-level system coupled with two cavity modes is studied. The two-level system is driven by a near-resonant strong laser such that the Mollow regime dominates the physical processes in this system. Under certain resonance conditions, a perfect super-Rabi oscillation between the zero-photon state $|0\rangle_{a}|0\rangle_{b}$ and the ($n+m$)-photon state $|n\rangle_{a}|m\rangle_{b}$ of the two cavity modes can take place. Induced by the photon decay, the two-mode correlated multiphoton bundle emission occurs in this system. More importantly, the results show that there is an antibunching effect between the strongly-correlated photon bundles, so that the system behaves as an antibunched ($n+m$)-photon source. The work opens up a route towards achieving two-mode correlated multiphoton source device, which has potential applications in modern quantum technology.

description: A theoretical frame for pump-probe photoemission is presented. The approach is based on a general formulation using the Keldysh formalism for the lesser Green's function to describe the real-time evolution of the electronic degrees of freedom in the initial state after a strong pump pulse that drives the system out of equilibrium. The final state is represented by a time-reversed low-energy electron diffraction state. Our one-step description is related to Pendry's original formulation of the photoemission process as close as possible. The formalism allows for a quantitative calculation of time-dependent photocurrent for simple metals where a picture of effectively independent electrons is assumed as reliable. The theory is worked out for valence- and core-electron excitations. It comprises the study of different relativistic effects as a function of the pump-probe delay.

Quantifying the urban environment: A scale measure of urbanicity outperforms the urban–rural dichotomy

description: The rapid urbanization of the developing world has important consequences for human health. Although several authorities have called for better research on the relationships between urbanicity and health, most researchers still use a poor measurement of urbanicity, the urban-rural dichotomy. Our goal was to construct a scale of urbanicity using community level data from the Cebu Longitudinal Health and Nutrition Survey. We used established scale development methods to validate the new measure and tested its performance against the dichotomy. The new scale illustrated misclassification by the urban-rural dichotomy, and was able to detect differences in urbanicity, both between communities and across time, that were not apparent before. Furthermore, using a continuous measure of urbanicity allowed for better illustrations of the relationships between urbanicity and health. The new scale is a better measure of urbanicity than the traditionally used urban-rural dichotomy.

Negative modes of Coleman-De Luccia bounces

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We investigate the negative modes about Coleman-De Luccia bounces governing vacuum transitions in de Sitter space, with the goal of gaining physical insight into the various anomalous results associated with these that have been reported in the literature. For the case of bounces with radii much less that the horizon distance $H^{-1}$ we find two distinct regimes, distinguished by the magnitude of the bubble nucleation rate $Γ$. If $Γ/H^4 \gg 1$, then the behavior of the modes contributing to the determinant factors in $Γ$ is much as in flat spacetime, and the calculation of $Γ$ goes over smoothly to the flat spacetime calculation as the gravitational coupling is taken to zero. This is not the case if $Γ/H^4 \ll 1$. These two regimes correspond to the two possible outcomes of de Sitter vacuum decay --- either a rapidly completed transition or non-percolation and eternal inflation. For bounces with radii comparable to the horizon length, we confirm previous results concerning anomalous negative modes with support on the bounce wall. We also find further evidence supporting previous claims, based on thin-wall arguments, of the absence of expected negative modes for a class of bounces that arises when the initial and final vacua are nearly degenerate.

Epidemiologic analysis of racial/ethnic disparities: Some fundamental issues and a cautionary example
Creators: name: Kaufman, Jay S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Racial/ethnic health disparities are a primary focus of epidemiologic research, encompassing both sociological hypotheses about differential treatment as well as biomedical hypotheses about distinctive etiologic processes that might underlie observed disparities. These two main currents in disparities research are often pitted against one another as opposing paradigms. Despite contentious debate about the balance between these hypotheses in the etiology of existing disparities, one consideration that has been largely ignored is that there are important distinctions in the statistical justifications for these two types of inferences. In this article I review the foundations of causal inference in etiologic epidemiology as applied to studies of racial/ethnic health disparities. I describe normative applications of quantitative techniques for causal inference as they are practiced in research on discrimination in health care and also for research on innate predisposition. I then show why the latter is an injudicious application of this statistical methodology, and illustrate this point with the example of an influential study in the biomedical literature that purported to demonstrate a lesser response to angiotensin-converting-enzyme inhibitor therapy in black as compared with white patients with left ventricular dysfunction.

description: Ultracold atoms in optical lattices have proven to provide an extremely clean and controlled setting to explore quantum many-body phases of matter. Now, imaging of atoms in such lattice structures has reached the level of single-atom sensitive detection combined with the highest resolution down to the level of individual lattice sites. This has opened up fundamentally new opportunities for the characterization and the control of quantum many-body systems. Here we give a brief overview of this field and explore the opportunities offered for future research.

description: China’s health profile has shifted to one dominated by obesity and nutrition-related noncommunicable diseases (NR-NCDs) necessitating an examination of how economic policies can improve this situation. Edible oil consumption is responsible for much of the increase in energy density of the Chinese diet and particularly linked with the shifting burden of NR-NCDs toward the poor. Longitudinal analysis among adults in the China Health and Nutrition Survey (CHNS) covering the period 1991 to 2000 revealed that price policy effects on edible oil can influence dietary composition (particularly of the poor) and the results identify a key preventive policy need.
