SHELS: A COMPLETE GALAXY REDSHIFT SURVEY WITH R ⩽ 20.6

The SHELS (Smithsonian Hectospec Lensing Survey) is a complete redshift survey covering two well-separated fields (F1 and F2) of the Deep Lens Survey to a limiting R = 20.6. Here we describe the redshift survey of the F2 field (R.A.2000 = 091932.ˢ4 and decl.2000 = +30°00′00″). The survey includes 16,294 new redshifts measured with the Hectospec on the MMT. The resulting survey of the 4 deg2 F2 field is 95% complete to R = 20.6, currently the densest survey to this magnitude limit. The median survey redshift is z = 0.3; the survey provides a view of structure in the range 0.1 ≲ z ≲ 0.6. An animation displays the large-scale structure in the survey region. We provide a redshift, spectral index Dn4000, and stellar mass for each galaxy in the survey. We also provide a metallicity for each galaxy in the range 0.2 <z < 0.38. To demonstrate potential applications of the survey, we examine the behavior of the index Dn4000 as a function of galaxy luminosity, stellar mass, and redshift. The known evolutionary and stellar mass dependent properties of the galaxy population are cleanly evident in the data. We also show that the mass–metallicity relation previously determined from these data is robust to the analysis approach.
Are only-children different? Evidence from a lab-in-the-field experiment of the Chinese one-child policy

In this paper, we present evidence from a lab-in-the-field experiment of the effects of the Chinese one-child policy on adults in China who were born just before and after the introduction of the policy. We measure risk, uncertainty, and time preferences, as well as subjects’ preferences in the social domain, i.e., concerning competitiveness, cooperation, and bargaining. We sampled people from three Chinese provinces born both before and after the introduction of the policy in 1979. We utilize the fact that the one-child policy was introduced at different times and with different degrees of strictness in different provinces. Overall, we find a statistically significant effect only on risk and uncertainty aversion and not on any other preferences in the experiments: Those born after the introduction of the one-child policy are less risk and uncertainty averse. These results hold for various robustness checks and heterogeneity tests. Hence, our results do not confirm the general wisdom and stereotype of only-children in China being “little emperors. ”
Compliance of non-pharmacological preventive practice of venous thromboembolism among Jordanian nurses

Many practices, such as non-pharmacological preventive practices, have demonstrated significant improvement and reduced the venous thromboembolism incidence. This study aims at investigating the compliance with non-pharmacological preventive practice of venous thromboembolism guidelines among Jordanian intensive care and medical and surgical nurses. Descriptive and cross-sectional with the non-participant observational design was used. This study recruited 271 registered nurses in adult medical-surgical units and intensive care units of 12 different government hospitals in Jordan’s middle and north regions. The observational checklist included 10 preventive practices based on the non-pharmacological preventive of venous thromboembolism guidelines. In the observational checklist, the highest score was 20, and the lowest was 0. If the nurse received equal to or higher than (>14) score were classified as sufficient compliance, while insufficient compliance was (≤14) score. The observations period started from September 2019 until March 2020. The participants’ overall mean venous thromboembolism compliance score was insufficient compliance (10.6 ± 1.6). The majority of nurses were classified as insufficient compliance 67%. “Doing foot exercise and early ambulation 2 times per day 50.3%” and “checked the integrity of the patient’s skin at regular intervals 50.0%” were the highest practices done rightly and completely by half of the participants. The participants who had a bachelor of nursing degree, staff nurse, and works in the intensive care unit, are less experienced and have no previous venous thromboembolism education reported low venous thromboembolism compliance. This study presents expanded compliance regarding venous thromboembolism preventive practices among Jordanian intensive care and medical & surgical nurses, so the policymakers need to develop an initiative to improve nurses’ compliance.
Born's rule from measurements of classical signals by threshold detectors which are properly calibrated

The very old problem of the statistical content of quantum mechanics (QM) is studied in a novel framework. The Born's rule (one of the basic postulates of QM) is derived from theory of classical random signals. We present a measurement scheme which transforms continuous signals into discrete clicks and reproduces the Born's rule. This is the scheme of threshold type detection. Calibration of detectors plays a crucial role. Creation of such a detection model provides a possibility to represent the basic quantum phenomena as classical field phenomena completed by measurements with threshold type and properly calibrated detectors. Finally, the wave-particle duality has been resolved in favor of the purely wave description. It is well known that coincidence probability plays an important role in the debate on the possibility to reduce quantum theory (especially quantum optics) to classical field theory. Our model matches well the predictions of quantum theory and experiment. It violates the prediction of the classical field model which does not take into account the presence of threshold type detectors with proper calibration.
Mast cells disrupt the duodenal mucosal integrity: Implications for the mechanisms of barrier dysfunction in functional dyspepsia

Abstract Background Functional dyspepsia (FD) is a common functional gastrointestinal (GI) disorder, but its pathophysiology is poorly understood. Mast cells (MCs) may play a critical role in the development of FD. Therefore, the aim of this study was to investigate the effect of MCs on barrier function, tight junction (TJ) proteins and related signaling pathways. Methods The expression of the TJ proteins claudin-8, ZO-1 and occludin in biopsy tissues from seven FD patients and five controls was assessed. Based on the in vivo results, we further investigated the effect of (1) MC degranulation in a coculture model of Caco-2/RBL-2H3 cells and tryptase in Caco-2 monolayers, (2) MC degranulation in the presence or absence of a PAR-2 antagonist and (3) MC degranulation in the presence or absence of an ERK1/2 signaling pathway inhibitor. The epithelial integrity of Caco-2 cell monolayers was assessed by measuring the transepithelial electrical resistance (TEER). The expression of TJ proteins was evaluated by western blotting, QT-PCR and immunostaining. Results Epithelial claudin-8, ZO-1 and occludin protein expression were significantly reduced in tissues from FD patients compared with controls. MC degranulation and tryptase decreased the TEER and reduced the expression of TJ proteins in Caco-2 cell monolayers. A PAR-2 antagonist and an ERK1/2 signaling pathway inhibitor significantly reduced the effect of MC degranulation on the TEER and TJ protein expression in Caco-2 cell monolayers. Conclusions MCs disrupt duodenal barrier function by modulating the levels of TJ proteins, and the PAR-2 and ERK1/2 signaling pathways may mediate the pathogenesis of FD.
On weak shock diffraction in real gases

Asymptotic solutions are obtained for the two-dimensional Euler system for real gases with appropriate boundary conditions which describe the diffraction of a weak shock at a right-angled wedge; the real gas effects are characterized by a van der Waals type equation of state. The behavior of the flow configuration influenced by the real gas effects, that includes the local structure near a singular point, is studied in detail.
Intricacies of cosmological bounce in polynomial metric f(R) gravity for flat FLRW spacetime

In this paper we present the techniques for computing cosmological bounces in polynomial f(R) theories, whose order is more than two, for spatially flat FLRW spacetime. In these cases the conformally connected Einstein frame shows up multiple scalar potentials predicting various possibilities of cosmological evolution in the Jordan frame where the f(R) theory lives. We present a reasonable way in which one can associate the various possible potentials in the Einstein frame, for cubic f(R) gravity, to the cosmological development in the Jordan frame. The issue concerning the energy conditions in f(R) theories is presented. We also point out the very important relationships between the conformal transformations connecting the Jordan frame and the Einstein frame and the various instabilities of f(R) theory. All the calculations are done for cubic f(R) gravity but we hope the results are sufficiently general for higher order polynomial gravity.
Non-perturbative approach for curvature perturbations in stochastic δ N formalism

In our previous paper [1], we have proposed a new algorithm to calculate the power spectrum of the curvature perturbations generated in inflationary universe with use of the stochastic approach. Since this algorithm does not need the perturbative expansion with respect to the inflaton fields on super-horizon scale, it works even in highly stochastic cases. For example, when the curvature perturbations are very large or the non-Gaussianities of the curvature perturbations are sizable, the perturbative expansion may break down but our algorithm enables to calculate the curvature perturbations. We apply it to two well-known inflation models, chaotic and hybrid inflation, in this paper. Especially for hybrid inflation, while the potential is very flat around the critical point and the standard perturbative computation is problematic, we successfully calculate the curvature perturbations.
Ferroelectric van der Waals heterostructures of CuInP2S6 for non-volatile memory device applications

Two-dimensional (2D) ferroelectric materials are providing promising platforms for creating future nano- and opto-electronics. Here we propose new hybrid van der Waals heterostructures, in which the 2D ferroelectric material CuInP2S6 (CIPS) is layered on a 2D semiconductor for near-infrared (NIR) memory device applications. Using density functional theory, we show that the band gap of the hybrid bilayers formed with CIPS can be tuned and that the optical and electronic properties can be successfully modulated via ferroelectric switching. Of the 3712 heterostructures considered, we identified 19 structures that have a type II band alignment and commensurate lattice matches. Of this set, both the CuInP2S6/PbSe and CuInP2S6/Ge2H2 heterostructures possess absorption peaks in the NIR region that change position and intensity with switching polarisation, making them suitable for NIR memory devices. The CuInP2S6/ISSb, CuInP2S6/ISbSe, CuInP2S6/ClSbSe and CuInP2S6/ZnI2 heterostructures had band gaps which can be switched from direct to indirect with changing the polarisation of CIPS making them suitable for optoelectronics and sensors. The heterostructures formed with CIPS are exciting candidates for stable ferroelectric devices, opening a pathway for tuning the band alignment of van der Waal heterostructures and the creation of modern memory applications that use less energy.
A MULTI-WAVELENGTH ANALYSIS OF NGC 4178: A BULGELESS GALAXY WITH AN ACTIVE GALACTIC NUCLEUS

We present Gemini longslit optical spectroscopy and Very Large Array radio observations of the nuclear region of NGC 4178, a late-type bulgeless disk galaxy recently confirmed to host an active galactic nucleus (AGN) through infrared and X-ray observations. Our observations reveal that the dynamical center of the galaxy is coincident with the location of the Chandra X-ray point source discovered in a previous work, providing further support for the presence of an AGN. While the X-ray and IR observations provide robust evidence for an AGN, the optical spectrum shows no evidence for the AGN, underscoring the need for the penetrative power of mid-IR and X-ray observations in finding buried or weak AGNs in this class of galaxy. Finally, the upper limit to the radio flux, together with our previous X-ray and IR results, is consistent with the scenario in which NGC 4178 harbors a deeply buried AGN accreting at a high rate.
Overcoming the Interobserver Variability in Lung Adenocarcinoma Subtyping.

CONTEXT. — The accurate identification of different lung adenocarcinoma histologic subtypes is important for determining prognosis but can be challenging because of overlaps in the diagnostic features, leading to considerable interobserver variability. OBJECTIVE. — To provide an overview of the diagnostic agreement for lung adenocarcinoma subtypes among pathologists and to create a ground truth using the clustering approach for downstream computational applications. DESIGN. — Three sets of lung adenocarcinoma histologic images with different evaluation levels (small patches, areas with relatively uniform histology, and whole slide images) were reviewed by 18 international expert lung pathologists. Each image was classified into one or several lung adenocarcinoma subtypes. RESULTS. — Among the 4702 patches of the first set, 1742 (37%) had an overall consensus among all pathologists. The overall Fleiss κ score for the agreement of all subtypes was 0.58. Using cluster analysis, pathologists were hierarchically grouped into 2 clusters, with κ scores of 0.588 and 0.563 in clusters 1 and 2, respectively. Similar results were obtained for the second and third sets, with fair-to-moderate agreements. Patches from the first 2 sets that obtained the consensus of the 18 pathologists were retrieved to form consensus patches and were regarded as the ground truth of lung adenocarcinoma subtypes. CONCLUSIONS. — Our observations highlight discrepancies among experts when assessing lung adenocarcinoma subtypes. However, a subsequent number of consensus patches could be retrieved from each cluster, which can be used as ground truth for the downstream computational pathology applications, with minimal influence from interobserver variability.
Physician Perception of the Importance of Medical Genetics and Genomics in Medical Education and Clinical Practice

ABSTRACT The importance of medical genetics and genomics in medical practice has grown proportionally with scientific advances in these areas. Purpose The objective of this study was to determine physician perceptions regarding the importance of and comfort with the use of medical genetics and genomics in medical education and practice, as well as physician expectations for medical trainees. Methods A retrospective survey was sent to physicians employed by a health system associated with a public medical school to assess their perceived training in medical genetics and genomics and their comfort level with ordering genetic testing. Results Despite reporting formal genetics training in medical schools, clinicians’ comfort with and knowledge in this content area does not meet personal expectations of competency. Though physicians report some discomfort with the use of medical genetics and genomics, the majority also believe that its impact on practice will increase in the next five years. Survey recipients were also asked about their expectations for preparation in the same domains for medical students and incoming residents. The surveyed physicians expect a high level of competency for medical students and incoming residents. Conclusions Our study revealed that practicing physicians feel current medical curricula do not produce physicians with the necessary competency in medical genetics and genomics. This is despite physicians’ perceived importance of this domain in medical practice. Our findings suggest a need for re-evaluation of medical genetics and genomics education at all levels of training.
Why Wolbachia-induced cytoplasmic incompatibility is so common

Significance Wolbachia are obligately intracellular alphaproteobacteria that infect approximately half of all insect species. Maternal inheritance of these endosymbionts produces selection to enhance female fitness. In addition to mutualistic phenotypes such as nutrient provisioning, Wolbachia produce various reproductive manipulations that favor infected females. Most common is cytoplasmic incompatibility, namely reduced embryo viability when Wolbachia-infected males fertilize Wolbachia-uninfected females. The regular loss of cytoplasmic incompatibility indicates this phenotype is not favored by natural selection among Wolbachia variants within host populations. Instead, we argue that cytoplasmic incompatibility is pervasive because it enhances interspecific transmission and intraspecific persistence. Specifically, cytoplasmic incompatibility produces high prevalence frequencies within host populations and allows Wolbachia to persist in host species even when their mutualist phenotypes wane or vanish.
Uniform estimates for positive solutions of semilinear elliptic equations and related Liouville and one-dimensional symmetry results

We consider a semilinear elliptic equation with Dirichlet boundary conditions in a smooth, possibly unbounded, domain. Under suitable assumptions, we deduce a condition on the size of the domain that implies the existence of a positive solution satisfying a uniform pointwise estimate. Here, uniform means that the estimate is independent of the domain. The main advantage of our approach is that it allows us to remove a restrictive monotonicity assumption that was imposed in the recent paper. In addition, we can remove a non-degeneracy condition that was assumed in the latter reference. Furthermore, we can generalize an old result, concerning semilinear elliptic nonlinear eigenvalue problems. Moreover, we study the boundary layer of global minimizers of the corresponding singular perturbation problem. For the above applications, our approach is based on a refinement of a result, concerning the behavior of global minimizers of the associated energy over large balls, subject to Dirichlet conditions. Combining this refinement with global bifurcation theory and the sliding method, we can prove uniform estimates for solutions away from their nodal set. Combining our approach with a-priori estimates that we obtain by blow-up, a doubling lemma, and known Liouville type theorems, we can give a new proof of a known Liouville type theorem without using boundary blow-up solutions. We can also provide an alternative proof, and a useful extension, of a Liouville theorem, involving the presence of an obstacle. Making use of the latter extension, we consider the singular perturbation problem with mixed boundary conditions. Moreover, we prove some new one-dimensional symmetry and rigidity properties of certain entire solutions to Allen-Cahn type equations, as well as in half spaces, convex cylindrical domains. In particular, we provide a new proof of Gibbons' conjecture in two dimensions.
From visco to perfect plasticity in thermoviscoelastic materials

We consider a thermodynamically consistent model for thermoviscoplasticity. For the related PDE system, coupling the heat equation for the absolute temperature, the momentum balance with viscosity and inertia for the displacement variable, and the flow rule for the plastic strain, we propose two weak solvability concepts, ‘entropic’ and ‘weak energy’ solutions, where the highly nonlinear heat equation is suitably formulated. Accordingly, we prove two existence results by passing to the limit in a carefully devised time discretization scheme. Furthermore, we study the asymptotic behavior of weak energy solutions as the rate of the external data becomes slower and slower, which amounts to taking the vanishing‐viscosity and inertia limit of the system. We prove their convergence to a global energetic solution to the Prandtl‐Reuss model for perfect plasticity, whose evolution is ‘energetically’ coupled to that of the (spatially constant) limiting temperature.
Initial Laboratory Values Can Predict Mortality in Burn Patients.

BACKGROUND There are several burn scores used to predict mortality in burn patients. However, minimal data exists on the role of laboratory values in risk stratification. We hypothesized that laboratory derangements seen on admission can predict mortality in burn patients. MATERIALS AND METHODS A retrospective chart review was conducted on burn patients admitted to a busy Level 1 Trauma and Burn Center from 2013 to 2019. Data analysis included patients with partial or full thickness burns and a total body surface area (TBSA) burn greater than 15%. Exclusion criteria included patients presenting with electrical burns, non-thermal conditions (Stevens-Johnson Syndrome, Toxic Epidermal Necrolysis, or soft tissue infections) or patients with significant polytrauma. RESULTS 112 patients were included in the analysis. Admission phosphate, creatinine, albumin, and glucose levels were associated with mortality. There was a difference in serum phosphate (3.48 and 6.04 mg/dL), creatinine (0.85 and 1.13 mg/dL), albumin (3.26 and 2.3 mg/dL), and glucose (138 and 233 mmol/L) levels for survivors and non-survivors; respectively. There were increased mortality rates seen in patients presenting with abnormal serum levels compared to normal serum levels (Phosphate: 7.5% vs. 53.3%, creatinine: 13.5% vs. 38.9%, albumin: 38.5% vs. 8.10% and glucose: 10.1% vs. 31.6% (normal vs. abnormal; respectively)). Serum sodium, potassium, and hemoglobin levels had no association with mortality. DISCUSSION Specific laboratory derangements seen on admission are associated with an increased risk for mortality. This can be used as a framework for future studies in risk stratification of burn victims.
Homological and Bloch invariants for Q-rank one spaces and flag structures

We use group homology to define invariants in algebraic K-theory and in an analogue of the Bloch group for Q-rank one lattices and for some other geometric structures. We also show that the Bloch invariants of CR structures and of flag structures can be recovered by a fundamental class construction.
The Nexus of Violent Victimization, Mental Health, and Employment: Findings From a Sample of Post-Incarcerated Individuals

The goals of this study were to assess the prevalence of victimization among people who are transitioning from prison to the community, and to examine the nexus of violent victimization during reentry, mental health, and weekly work hours. The participants (n = 724; average age = 29.09 years) were interviewed before release, and in the 3rd, 9th, and 15th months into reentry. Longitudinal data about their mental health, work hours, family environment, and victimization were collected. We drew on Agnew’s general strain theory and employed multilevel longitudinal modeling to examine how victimization affected respondents’ work hours via mental health. Findings revealed that greater exposure to violent victimization deteriorated mental health among respondents. Furthermore, an indirect effect between victimization and reduced work capacity operating through poor mental health was observed at the between-person level. These results underscored the alarmingly high prevalence of victimization among reentering individuals and that maintaining stable employment, a critical step of reintegration after imprisonment, is difficult for reentering individuals when they become a victim of violence and suffer mental health deterioration. Implications for addressing victimization among people transitioning out of prison are discussed.
