A LDA+U and LDA+DMFT study of uranium mononitride: from nonmagnetic to paramagnetic and ferromagnetic
Authors: Sun Weiwei , Di Marco Igor , Korzhavyi Pavel 
Published: May 2014

ABSTRACTThe combination of density functional theory in local density approximation and dynamical mean field theory (LDA+DMFT) was employed in a preliminary study of the strong electron correlation effects in a promising nuclear fuel—uranium mononitride (UN). For the ferromagnetic phase, the effective impurity problem arising in the LDA+DMFT [1-3] cycle is solved with the spin-polarized T-matrix fluctuation exchange (SPTF) solver, which includes spin–orbit interactions. Concerning the paramagnetic phase, the disordered local moment (DLM) approach was used, based on both standard local density approximation (LDA) and LDA+U. Basic spectral properties and material properties, such as the spin, orbital and total magnetic moments on U atom were calculated for various values of the Hubbard parameter U with a fixed exchange parameter J. Our main focus was to compare the calculated spectral functions (density of states) for different magnetic phases and different methods to the experimental XPS data [4]. On top of that, the total moments of the paramagnetic and ferromagnetic phases are compared with the measured values by neutron spectroscopy [4, 5].
Industry Audit Experts and Ownership Structure in the Syndicated Loan Market: At the Firm and Partner Levels
Authors: Chin Chen-Lung , Yao Wei-Ren , Liu Pei-Yi 
Published: May 2014

SYNOPSIS
The PCAOB has recently issued two concept releases that seek feedback on a proposal that requires audit firms to disclose the name of the engagement partner in the audit report. This paper provides evidence about the efficacy of this proposal by examining whether industry audit experts at the partner level are valued by stakeholders—lenders in the syndicate loan market. Our paper is based on the unique data in Taiwan, where the audit report is issued in the name of two signing auditors, as well as the audit firm. Prior research suggests that lead arrangers prefer to hold a lower share of the loan and to have a larger number of other lenders. First, we find no evidence that Big 4 audit firms are related to the lower share of a syndicated loan held by the lead arrangers, after controlling for industry audit expertise; we also find no evidence that firm-level expertise alone is associated with the share held by lead arrangers. However, we do find that partner-level industry audit experts, either alone or in conjunction with a firm-level industry audit expert, are associated with the lower share of syndicated loans held by lead arrangers. Second, we find that the number of lenders in general (or the number of foreign lenders in particular) in a loan is the largest when borrowers retain industry audit experts at both the firm and partner levels.
A Study of Assimilation Bias in Name-Based Sampling of Migrants
Authors: Schnell Rainer , Trappmann Mark , Gramlich Tobias 
Published: May 2014

Abstract
The use of personal names for screening is an increasingly popular sampling technique for migrant populations. Although this is often an effective sampling procedure, very little is known about the properties of this method. Based on a large German survey, this article compares characteristics of respondents whose names have been correctly classified as belonging to a migrant population with respondentswho aremigrants and whose names have not been classified as belonging to a migrant population. Although significant differences were found for some variables even with some large effect sizes, the overall bias introduced by name-based sampling (NBS) is small as long as procedures with small false-negative rates are employed.

Published: May 2014

Abstract
In this paper distortion of surface topography measurement results by improper selection of the reference plane is taken into consideration. The following types of surfaces from cylindrical elements were analyzed: cylinder liners after plateau honing, cylinder liners with additionally burnished oil pockets and turned piston skirts. Surface topographies of these elements after a low wear process were also studied. In order to obtain areal surface topography parameters, the form was eliminated using cylinders and polynomials of the following degrees: 2, 3, 4, 6, 8, 10 and 12. Parameters of surfaces after form removal were compared. After analysis of results the reference elements for each kind of surface were recommended. A special procedure was proposed in order to select the degree of a polynomial. This method is based on surface topography changes with increase of polynomial degree. The effect of improper form elimination on measuring uncertainty was studied.
Complications of Implanting Three-Piece C-Loop Posterior Chamber Lenses in the Anterior Chamber
Authors: Liu John F , Koch Douglas D , Emery Jared M 
Published: May 2014

ABSTRACT
We have examined a total of four eyes in three patients who had undergone implantation of threepiece C-loop posterior chamber intraocular lenses into the anterior chamber. All four eyes exhibited four or more of the following complications: 1) loop encapsulation by peripheral anterior synechiae; 2) recurrent iritis; 3) central loop displacement with corneal endothelial touch; 4) progressive endothelial cell loss and corneal edema; 5) glaucoma; and 6) cystoid macular edema. Intraocular lens removal was required in all four eyes, and penetrating keratoplasty was performed in one. We believe that these complications are attributable to the inherent fallacies of fixating threepiece open-loop lenses in the anterior chamber angle.
An Improved Approach to Aqueous Paracentesis
Authors: May Donald R , Noll Francis G 
Published: May 2014

ABSTRACT
We describe a quick and effective technique for performing safe anterior chamber paracenteses. The technique consists simply of inserting a small gauge disposable hypodermic needle without an attached syringe into the anterior chamber. The intraocular pressure and capillary action of the needle readily cause the rapid drainage of aqueous humor. This technique eliminates the cumbersome manipulations and potential complications associated with using an attached syringe for aspiration.
L’écologie politique de la ville
Authors: Durand-Folco Jonathan 
Published: May 2014

Loin de se limiter à l’évangile de l’éco-efficience de l’urbanisme durable, l’écologie politique de la ville vise à favoriser la relocalisation économique, le développement communautaire et la démocratie participative à travers la promotion de la « sphère autonome ». Néanmoins, l’extension de cette sphère nécessite du temps, actuellement contraint par la logique économique du régime postfordiste. Une défense du revenu suffisant garanti sera présentée à partir de la perspective de l’écologie politique et la pensée d’André Gorz, afin de montrer comment la libération du temps permet de multiplier les activités autonomes au sein de l’espace urbain.
Licensing Requirements and Occupational Mobility Among Highly Skilled New Immigrants in Canada
Authors: Banerjee Rupa , Phan Mai 
Published: May 2014

The present study compares the occupational trajectories of highly skilled immigrants in regulated occupations to those outside of the regulated occupations, from their pre-migration occupation, to their first job in Canada, and to subsequent jobs. Licensing requirements are likely to affect new immigrants’ occupational trajectories since they have a direct effect on how employers assess qualifications. This study utilizes growth curve modeling (GCM) and a unique dataset that contains detailed information on new immigrants’ experiences in Canada: the Longitudinal Survey of Immigrants to Canada (LSIC).
Our findings indicate that immigrants working in regulated occupations prior to migration who are unable to find jobs in regulated occupations in Canada face a significantly greater drop in occupational status when they first arrive than those working in unregulated professions in their home country. Furthermore, their occupational progression over time is not faster than that of their counterparts from unregulated professions. Those who worked in unregulated fields prior to migration but found jobs in regulated fields in Canada experience an improvement in their occupational status after migration. Lastly, for those who worked in regulated professions in their home country and were able to find jobs within regulated fields in Canada, initial occupational status scores are similar to their scores in their country of origin, and there is little change in occupational status with time in Canada.
The results of this study highlight the importance of ensuring that the licensing process is made easier to navigate for new immigrants. Our findings clearly indicate that immigrants who are able to successfully enter a regulated profession soon after migration fare much better in terms of occupational status than those who are unable to become licensed.
Les effets possibles de la formation sur la productivité : l’apport de données longitudinales
Authors: Bernier Amélie 
Published: May 2014

Cet article analyse les effets possibles des dépenses de formation formelle sur la productivité des entreprises canadiennes. Si certains travaux mesurent l’intensité de la formation en entreprise à partir de données longitudinales, les résultats obtenus demeurent partagés. Les différences observées dans les résultats antérieurs peuvent être expliquées notamment par les données disponibles, le type de formation, la mesure de formation et les biais techniques influençant cette relation. Cette recherche s’appuie essentiellement sur la théorie du capital humain.
Notre étude s’appuie sur les données de l’Enquête sur les milieux de travail et les employés (EMTE) de Statistique Canada de 1999 à 2005, auprès d’un échantillon de 1621 emplacements où, nous modélisons la relation entre la formation et la productivité à l’aide d’une fonction de production Cobb-Douglas, en intégrant les investissements en capital physique et une variable technologique. Ceci nous permet de montrer que les dépenses de formation contribuent à accroître la performance des établissements, via la productivité, de façon progressive dans le temps. Ces dépenses effectuées au cours d’une année donnée influent significativement sur la productivité jusqu’à trois années plus tard, là où elles atteignent leur maximum d’effet, pour se stabiliser par la suite. Toutefois, ces résultats permettent de soulever un paradoxe : celui de la rentabilité observée des dépenses de formation d’un côté, mais, de l’autre, l’hésitation du monde des affaires à investir en cette matière pour leurs propres employés. Nos résultats suggérent également que les investissements en formation au sein des entreprises devraient être considérés davantage comme un atout, plutôt qu’une simple obligation financière à l’appui d’une stratégie globale de développement des compétences au sein des entreprises.

ImportanceGiven the expiration of expanded unemployment and other benefits during the COVID-19 pandemic, it is important to understand the association between pandemic income or job loss and long-term implications on mental health.ObjectiveTo evaluate the association between income or job loss due to the COVID-19 pandemic and later psychological distress.Design, Setting, and ParticipantsThis cohort study used 5 waves of nationally representative, longitudinal survey data (September 16, 2019, through September 18, 2022) from the Pew Research Center’s American Trends Panel. Doubly robust propensity score–weighted quasi-Poisson models were used to estimate the association of self or household income or job loss during the early phase of the COVID-19 pandemic with later psychological distress, while controlling for pre–income loss characteristics (demographics, finances, and psychological distress). The study sample comprised US working-age adults (aged 18-64 years) who had not experienced income or job loss due to the COVID-19 pandemic by March 24, 2020.ExposureParticipant-reported self or household income or job loss (ie, reduced hours or demand for work) due to the COVID19 pandemic between March 24, 2020, and August 16, 2020.Main Outcome and MeasuresPsychological distress was measured using a composite scale of 0 to 15 based on participants’ reported frequency of feeling depressed, on edge, sleepless, lonely, and hopeless in the past week in March 2020, February 2021, and September 2022.ResultsOf 1392 working-age adults (survey weighted 52.7% male and 47.7% aged 30-49 years) who had not reported income or job loss before March 24, 2020, a survey weighted 35.7% reported job or income loss between March 24 and August 16, 2020. Early-phase pandemic income or job loss was associated with higher distress in February 2021 (estimated ratio, 1.09; 95% CI, 1.01-1.18; P = .03) and September 2022 (estimated ratio, 1.11; 95% CI, 1.02-1.22; P = .02) among participants who experienced job or income loss between March 24 and August 16, 2020, compared with the propensity score–weighted mean in the group who did not experience income loss.Conclusions and RelevanceThese small but significant within-person associations between early-phase pandemic household income or job loss and psychological distress up to 29 months later suggest that policies are needed to support people with income or job loss to help mitigate the long-term adverse mental health outcomes of economic disruption.

AbstractBackgroundData collected from hospitals are usually partially annotated by radiologists due to time constraints. Developing and evaluating deep learning models on these data may result in over or under estimationPurposeWe aimed to quantitatively investigate how the percentage of annotated lesions in CT images will influence the performance of universal lesion detection (ULD) algorithms.MethodsWe trained a multi‐view feature pyramid network with position‐aware attention (MVP‐Net) to perform ULD. Three versions of the DeepLesion dataset were created for training MVP‐Net. Original DeepLesion Dataset (OriginalDL) is the publicly available, widely studied DeepLesion dataset that includes 32 735 lesions in 4427 patients which were partially labeled during routine clinical practice. Enriched DeepLesion Dataset (EnrichedDL) is an enhanced dataset that features fully labeled at one or more time points for 4145 patients with 34 317 lesions. UnionDL is the union of the OriginalDL and EnrichedDL with 54 510 labeled lesions in 4427 patients. Each dataset was used separately to train MVP‐Net, resulting in the following models: OriginalCNN (replicating the original result), EnrichedCNN (testing the effect of increased annotation), and UnionCNN (featuring the greatest number of annotations).ResultsAlthough the reported mean sensitivity of OriginalCNN was 84.3% using the OriginalDL testing set, the performance fell sharply when tested on the EnrichedDL testing set, yielding mean sensitivities of 56.1%, 66.0%, and 67.8% for OriginalCNN, EnrichedCNN, and UnionCNN, respectively. We also found that increasing the percentage of annotated lesions in the training set increased sensitivity, but the margin of increase in performance gradually diminished according to the power law.ConclusionsWe expanded and improved the existing DeepLesion dataset by annotating additional 21 775 lesions, and we demonstrated that using fully labeled CT images avoided overestimation of MVP‐Net's performance while increasing the algorithm's sensitivity, which may have a huge impact to the future CT lesion detection research.

Published: July 2024

AbstractPeople sometimes lie by omitting information. The information lie tellers then report could be entirely truthful. We examined whether the truthful information that lie tellers report in omission lies contains verbal cues indicating that the person is lying. We made a distinction between (i) essential information (events surrounding the omission) and non‐essential information (the rest); and (ii) made a distinction between informing or not informing participants about the key event they witnessed. Participants followed a target person. Truth tellers reported all activities truthfully; lie tellers omitted the key event. Participants were or were not informed what this key event was. In the analyses we discarded the information truth tellers reported about the key event lie tellers omitted. Truth tellers reported more external and contextual details, more complications and fewer common knowledge details and self‐handicapping strategies than lie tellers, but only when discussing essential information. Being informed had no effect.

Published: July 2024

SummaryIn this article, the issue of resilient filtering for descriptor nonhomogeneous Markovian jump cyber‐physical systems under hybrid cyber‐attacks has been studied. First, occurrences of both deception attacks and replay attacks are modeled as two mutually independent Bernoulli distributed random variables. To depress the ratio of sampled data transmissions over the network, the dynamic version of event‐triggered transmission policy is properly proposed. Then, criteria of stochastically admissible for the filtering error systems guaranteeing mixed and passive performance are addressed via linear matrix inequalities (LMIs). The gains of resilient filter and the dynamic event‐based transmission policy can be simultaneously gained by optimizing the LMIs. Finally, two examples that include a numerical example and a direct current motor system are provided to testify the feasibility and effectiveness of the developed technique.

Published: July 2024

AbstractThe role of glial scars in the pathophysiology of spinal cord injury (SCI) is widely recognized, as they pose physical barriers against axonal regeneration and persistent chronic inflammation by releasing cytotoxic agents, thereby impeding nerve repair. Consequently, preventing glial scarring has emerged as an important therapeutic objective in SCI management. Following SCI, astrocytes undergo a phenotypic transition into scar‐forming astrocytes, which critically depends on the activation of inflammatory responses and the integrin‐N‐cadherin pathway. To explore improved SCI treatment, a nano‐antagonist hydrogel (Nano‐ant Gel), comprising N‐cadherin nano‐antagonists and a polyphenol hydrogel designed to inhibit glial scarring by mitigating inflammatory response and modulating astrocyte behavior, thereby facilitating spinal cord‐injury repair, is developed and characterized. The hydrogel exhibits notable anti‐inflammatory properties, specific calcium ion‐adsorption capabilities, and antagonistic effects against N‐cadherin, effectively impeding the formation and aggregation of scar‐forming astrocytes. Its efficacy is comprehensively assessed using a model of contusive SCI, with which it effectively inhibits glial scar formation and promotes axonal regeneration. Notably, the Nano‐ant Gel significantly improves the locomotor functions of mice with SCI, suggesting that it represents a promising approach for treating the condition.

Published: July 2024

AbstractFor an ideal electrostatic energy storage dielectric capacitor, the pursuit of simultaneously high energy density and efficiency presents a formidable challenge. Typically, under an applied electric field, an increase in energy density is usually accompanied with a deteriorated energy storage efficiency due to the escalated hysteretic loss, which is harmful to the reliability of the capacitor. Thus, a well‐balanced performance of improved energy density and maintained high efficiency is highly demanded. In this work, a structure with amorphous phases embedded in polycrystalline nanograins using the entropy tactic, leading to a higher transport barrier of carrier is constructed. Hence, the hysteretic loss is largely suppressed at a high electric field and the high polarization is still sustained in the high‐entropy film. Consequently, an ultrahigh energy density of 139.5 J cm−3 with a high efficiency of 87.9%, and a high figure of merit of 1153 are simultaneously achieved in the high‐entropy Ba2Bi4Ti5O18‐based relaxor ferroelectric. This work offers a promising avenue in materials structure design for advanced high‐power energy storage applications.

Published: July 2024

AbstractThe redox‐active organic compounds including potassium 1,1′‐biphenyl‐4,4′‐dicarboxylate (K‐BPDC) are attracting considerable attention as anodes for potassium‐ion batteries (PIBs). Nevertheless, the practical applications of K‐BPDC organic anodes are severely hindered by short cycle life due to their relatively sluggish redox kinetics and instability. In this work, Ni single atoms (up to 6 wt.%) are implanted into K‐BPDC (NiSA@K‐BPDC) by using an electrochemical‐induced reconstruction (EIR) strategy to enhance the reaction kinetics and stability of PIBs. During the EIR process, Ni‐based metal‐organic framework (Ni‐BPDC) is in situ reconstructed into K‐BPDC by replacing Ni2+ with K+ to make the rest nickel species exist in the form of single atoms in K‐BPDC. By kinetic analysis and theoretical calculations, it is uncovered that the Ni single atoms supported on K‐BPDC efficiently redistribute the local charge of K‐BPDC to accelerate the K+ transport rate, and thermodynamically reduce the redox energy barrier. As a result, the NiSA@K‐BPDC anode exhibits outstanding cycle stability with 88.5% capacity retention during 4000 cycles at 1 A g−1 and an excellent rate capability (114 mAh g−1 at 2 A g−1). This study opens up a new door to the design of organic anodes with single atoms for high‐performance PIBs.
