description: We revisit the idea of self-tuning the observed cosmological constant to a vanishing value and promote it to a selection criterion of brane-world models, in which our Universe is described by a 3-brane embedded in a 5d bulk. As a concrete setup, we consider a bulk scalar field $ϕ$ described by a general Lagrangian $P(X,ϕ)$ with $X=-(\partialϕ)^2/2$. By requiring that the model enforces the 4d curvature of the maximally symmetric 3-brane world-volume to vanish independently of the 4d effective vacuum energy, only two possibilities remain: one with a canonical bulk kinetic term and the other with an unconventional bulk kinetic term similar to a Cuscuton field. Further demanding the absence of bulk singularity, the latter is selected as a unique possibility within the class of models. At the background level, the solution can accommodate any warp factor profile free from bulk singularity and with a finite effective 4d Planck mass. In a cosmological context, our solution would describe our (almost) flat Universe at late times, with a bulk warp factor profile expected to be determined by the evolution of the Universe before dilution of the matter fields by cosmic expansion. Eventually, a simple analysis is performed in the bulk showing no obvious instability around the background solution. A full stability analysis taking into account brane bending modes is nevertheless necessary and left for future work.

description: We reveal the origin and structure of self-consistent source extensions of integrable equations from the perspective of binary Darboux transformations. They arise via a deformation of the potential that is central in this method. As examples, we obtain in particular matrix versions of self-consistent source extensions of the sine-Gordon, nonlinear Schrodinger, KdV, Boussinesq, KP, Davey-Stewartson, two-dimensional Toda lattice and discrete KP systems. We also recover a (2+1)-dimensional version of the Yajima-Oikawa system from a deformation of the pKP hierarchy. By construction, these systems are accompanied by a hetero binary Darboux transformation, which generates solutions of such a system from a solution of the source-free system and additionally solutions of an associated linear system and its adjoint. The essence of all this is encoded in universal equations in the framework of bidifferential calculus.

description: Dimethyl 4,4'-(ethane-1,2-diyl)dibenzoate, a dibenzyl derivative. It was synthesized in one step and confirmed by 13C NMR, 1H NMR, FT-IR, UV–vis, and MS spectroscopies. At the B3LYP/6-311 + G(2d, p) level, we used density functional theory (DFT) to optimize the molecular structure and determine the optimal structure of the title compound. The conformational analysis results showed that the optimized DFT molecular structure is consistent with the crystal structure determined using X-ray single-crystal diffraction. In addition, through more in-depth studies by MEP, FMOs, and Hirshfeld surfaces analysis of title compound, more physicochemical properties were investigated.
Discrete Interpersonal Stress Experiences and Prospective Suicidal Thoughts and Behaviors Across the Pubertal Transition

description: Suicide risk dramatically increases across the pubertal transition.  This study examined the relationship between two discrete interpersonal stressors, relational victimization and targeted rejection, and prospective suicide ideation and attempts.  The potential moderating effects of pubertal development were also observed.  160 adolescents (ages 12 to 18) at heightened risk for self-injurious behaviors were followed over an eighteen-month interval.  Participants completed phone-based assessments of suicidal thoughts and behaviors over the first nine months (Time 1) and the second nine months (Time 2).  Independently coded measures of relational victimization and targeted rejection were derived from interviews of life stress at Time 1.  Assessments of puberty and demographic information were collected at the beginning of Time 1.  Findings from logistic regression analyses indicated that relational victimization at Time 1 was associated with increased odds of suicide attempt but not ideation at Time 2, after accounting for prior suicidality and depressive symptoms.  Main and moderating effects of pubertal development were not significant.  The current study sheds light on potential discrete interpersonal stress experiences associated with heightened risk for suicidal thoughts and behaviors in adolescent females.  Evidence-based intervention programs and screening tools that directly target relational victimization are urgently needed.

description: To assess the predictive accuracy of code-based algorithms for identifying invasive Escherichia coli (E. coli) disease (IED) among inpatient encounters in US hospitals. The PINC AI Healthcare Database (10/01/2015–03/31/2020) was used to assess the performance of six published code-based algorithms to identify IED cases among inpatient encounters. Case-confirmed IEDs were identified based on microbiological confirmation of E. coli in a normally sterile body site (Group 1) or in urine with signs of sepsis (Group 2). Code-based algorithm performance was assessed overall, and separately for Group 1 and Group 2 based on sensitivity, specificity, positive and negative predictive value (PPV and NPV) and F1 score. The improvement in performance of refinements to the best-performing algorithm was also assessed. Among 2,595,983 encounters, 97,453 (3.8%) were case-confirmed IED (Group 1: 60.9%; Group 2: 39.1%). Across algorithms, specificity and NPV were excellent (>97%) for all but one algorithm, but there was a trade-off between sensitivity and PPV. The algorithm with the most balanced performance characteristics included diagnosis codes for: (1) infectious disease due to E. coli OR (2) sepsis/bacteremia/organ dysfunction combined with unspecified E. coli infection and no other concomitant non-E. coli invasive disease (sensitivity: 56.9%; PPV: 56.4%). Across subgroups, the algorithms achieved lower algorithm performance for Group 2 (sensitivity: 9.9%–61.1%; PPV: 3.8%–16.0%). This study assessed code-based algorithms to identify IED during inpatient encounters in a large US hospital database. Such algorithms could be useful to identify IED in healthcare databases that lack information on microbiology data.

description: We study the electronic structures of TiO2/Ti4O7 and Ta2O5/TaO2 interfaces using the screened exchange (sX-LDA) functional. Both of these bilayer structures are useful infrastructures for high performance RRAMs. We find that the system Fermi energies of both interfaces are just above the conduction band edge of the corresponding stoichiometric oxides. According to the charge transition levels of the oxygen vacancies in Ta2O5 and TiO2, the oxygen vacancies are stabilized at the -2 charged state. We propose to introduce interfacial dopants to shift the system Fermi energies downward so that the +2 charged oxygen vacancy can be stable, which is important for the controlled switching under the electrical field. Several dipole models are presented to account for the ability of Fermi level shift due to the interfacial dopants.

description: We selected the claim that the more differently valued are the issues over which states are bargaining, the more likely they are to offer concessions, all else constant (Hypothesis S1) (Statement 2). This reflects the following statement from the paper's abstract: "The results show that structural factors best explain variation in the EU states’ bargaining strategies" (Statement 1). The claim is tested with data on bargaining within the European Union. The bargaining strategy adopted by each EU state in each of 23 bargaining phases is analyzed, with each phase treated as its own bargaining interaction with its own bargaining structure. The unit of analysis is therefore “state-bargaining phase.” The dependent variable measures the degree of concession offering that characterizes a state’s bargaining strategy, and it takes on four ordered categories with larger values indicating more cooperative behavior, which is analyzed in an ordered logistic regression as a function of issue-linkage structure (the average zone of agreement across all issue pairs in the negotiation [larger values indicate that the issues by states with opposing interests are more differently valued]), four additional bargaining structure measures (agreement importance, parliamentary scrutiny, majority voting, and publicity), measures for power and socialization, and controls (see Model 1 of Table 1 for the full specification). The claim is tested with the coefficients on the issue-linkage structure term across each level of the dependent variable (the omitted level is the highest level of cooperation). The evidence for the claim used by the SCORE program is the coefficient on issue-linkage structure for the outcome of cooperative strategy = 0, though the full set of evidence is comprised of the coefficients across all levels of the dependent variable (Statement 3). Consistent with Hypothesis S1, negotiating over issues that are more differently valued by states with opposing interests exerts a positive and statistically significant effect on states’ bargaining strategies (coefficient on issue-linkage structure when cooperative strategy is 0 = 1.219, SE clustered by bargaining phase = 0.192, p < .05) (Statement 4). The focal test in the original paper is: Negotiating over issues that are more differently valued by states with opposing interests exerts a positive and statistically significant effect on states’ bargaining strategies (coefficient on issue-linkage structure when cooperative strategy is 0 = 1.219, SE clustered by bargaining phase = 0.192, p < .05)

description: The advent of noisy-intermediate scale quantum computers has introduced the exciting possibility of achieving quantum speedups in machine learning tasks. These devices, however, are composed of a small number of qubits, and can faithfully run only short circuits. This puts many proposed approaches for quantum machine learning beyond currently available devices. We address the problem of efficiently compressing and loading classical data for use on a quantum computer. Our proposed methods allow both the required number of qubits and depth of the quantum circuit to be tuned. We achieve this by using a correspondence between matrix-product states and quantum circuits, and further propose a hardware-efficient quantum circuit approach, which we benchmark on the Fashion-MNIST dataset. Finally, we demonstrate that a quantum circuit based classifier can achieve competitive accuracy with current tensor learning methods using only 11 qubits.

description: The COVID-19 pandemic significantly impacted and continues to impact the health and well-being of Australian adults. However, there has been no instrument validated to comprehensively measure how the COVID-19 pandemic impacted adults in Australia across several domains (e.g. fear of COVID-19, attitudes towards vaccination, psychosocial impact of lockdowns). The current study conducted a rigorous psychometric process to develop and validate an instrument to measure the impact of the COVID-19 pandemic in Australia, the COVID-19 Impact Scale (CIS). Data was obtained from the Australian population. Participants (N = 563) aged between 19 and 91 years (M = 54.50, SD = 16.16) provided online responses between June, 2021 and May, 2022. The majority of participants were female (60.9%), employed either full-time (37.7%) or part-time (22.0%), and had completed an undergraduate degree or higher (70.1%). An initial pool of 30 items was developed based on a review of the literature and input from a panel of experts including psychologists, epidemiologists, and public health experts, among others. The study used network psychometrics to examine the psychometric properties of: (1) item score distributions; (2) item redundancy; (3) dimensionality; (4) model fit; (5) measurement invariance; (6) reliability; and (7) criterion validity. Following an evaluation of items for ceiling/floor effects and redundancy, the final CIS network model included eighteen nodes and displayed a three-dimensional structure. The three communities of “Fear” (consisting of three nodes; ω = 0.82), “Attitudes” (consisting of ten nodes; ω = 0.89), and “Ill-being” (consisting of five nodes; ω = 0.79) displayed adequate reliability. The evaluation of model fit indicated a good fit of the network model (RMSEA = 0.047; CFI =0.98). The instrument is available to be used by Australian researchers and implemented to evaluate public policies, adapted for future pandemics, or used internationally.

description: Many natural language processing tasks, e.g., coreference resolution and semantic role labeling, require selecting text spans and making decisions about them. A typical approach to such tasks is to score all possible spans and greedily select spans for task-specific downstream processing. This approach, however, does not incorporate any inductive bias about what sort of spans ought to be selected, e.g., that selected spans tend to be syntactic constituents. In this paper, we propose a novel grammar-based structured span selection model which learns to make use of the partial span-level annotation provided for such problems. Compared to previous approaches, our approach gets rid of the heuristic greedy span selection scheme, allowing us to model the downstream task on an optimal set of spans. We evaluate our model on two popular span prediction tasks: coreference resolution and semantic role labeling. We show empirical improvements on both.

description: We study the dependence of the formation energies of oxygen and metal induced defects in Ta2O5, TaO2, TaO, TiO2 and Ti4O7 on the chemical potential of electron and atomic constitutes. In the study of single defect, metal induced defects are found to be preferable to oxygen induced defects. This is against the experimental fact of the dominant role of oxygen induced defects in the RS process. A simple multiple defects picture without correlated atomic rearrangement does not cure this problem. The problem is resolved under the correlated multiple defect picture where the multiple defects result in correlated atomic rearrangement and the final products show certain atomic ordering.

Nurses Supporting Nurses: Implementation of a Mentor Training Program to Improve New Graduate Registered Nurses' Sense of Belongingness
Creators: name: Phifer, Sheri
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Purpose: The purpose of this evidence-based, quality improvement project was to develop and implement a mentor training program for Registered Nurses who mentor new graduate registered nurses. The goal of the training was to foster a sense of belongingness among new graduate registered nurses in an acute care hospital. Background: New graduate registered nurse (NGRN) turnover is a critical issue for hospitals, as 35-60% of these nurses quit their jobs during the first year of employment. The use of mentors can help to ease NGRN transition to practice concerns and may help retain NGRNs during the first year of employment. Methods: A one-hour mentor training class was developed and offered to mentors. After training, mentors were matched with a NGRN employed in a different work unit who had a similar work shift and schedule. As part of this program, mentor-NGRN pairs met on a monthly basis. New graduate registered nurses’ perceptions of belongingness were measured before and three months after beginning the program using a modified version of the Belongingness Scale-Clinical Placement Experience survey (Levett-Jones, Lathlean, Higgins, & McMillian, 2008). Results: There were no differences in mean scores on the Belongingness Scale-Clinical Placement Experience survey as reported by NGRNs at pre-implementation and three-month post-implementation of the mentor training program. Also, the six-month NGRN turnover rate, for participants in this project was 9.37%, which is 3.83% higher than the same time in the previous year’s cohort. Conclusion: While the literature suggests that mentors can be an effective strategy for nurturing NGRNs during their early employment period, the findings of this project did not indicate that the training and assignment of mentors improved NGRNs’ sense of belongingness. Several limitations were noted in this study including a small sample size and a short time frame for evaluation. Nonetheless, these findings provide some insights into a NGRN mentor program that might help others.
title: Evolutionary Genetics and Conservation of the Critically Endangered Arabian Leopard (Panthera pardus nimr)
Creators: name: Al Hikmani, Hadi
Publisher: name: University of Kent
Year: 2019

description: Large carnivores are considered an important component of an ecosystem and their role as apex predators makes them crucial for maintenance of ecosystem function and biodiversity. Yet despite their important ecological value, large carnivores are among the world's most threatened species, mostly due to human persecution and loss of their habitat and prey species. The Arabian leopard (Panthera pardus nimr) is the region's last remaining big cat, and was once widely distributed across the Arabian Peninsula but its occupied range has contracted from ~888,300 km2 to 17,400 km2 since the 1970s, and it is listed as Critically Endangered on the IUCN Red List of Threatened Species. Despite its threatened status, scientific information is lacking for many aspects of the Arabian leopard, including its population and evolutionary genetics. The objectives of this study were therefore to improve the knowledge base to help develop better management strategies for the long-term persistence of the Arabian leopard. By generating a comprehensive mitochondrial DNA sequence database that included sequence data from wild Arabian leopard populations across the Arabian Peninsula my study provided evidence that the Arabian leopard is evolutionarily distinct from other leopard subspecies. Assessment of genetic diversity using a suite of microsatellite markers indicate that the Arabian leopard is genetically impoverished in comparison to other leopard subspecies. However, high levels of genetic diversity and unique alleles were discovered in wild and captive Arabian leopards of Yemeni origin, compared to the wild leopards of the Dhofar mountains of Oman, an area considered to be their last stronghold. Using genetic data from wild leopards obtained via non-invasive scat surveys, we detected fine-scale spatial genetic structure within the leopard population of Dhofar which is likely due to recent human development in the region. DNA surveys of the Dhofar population provided robust estimates of density and population size that are comparable with those derived from camera trap estimates, indicating the reliability of genetic sampling for monitoring of the Arabian leopard. Based on these findings a number of conservation management strategies are proposed including genetic rescue via introgression of Yemen genes to restore the genetic diversity of impoverished populations and enhance the overall evolutionary potential of the Arabian leopard. Other suggested measures include strengthening legislation and enforcement in combination with community engagement to ease human-wildlife conflict as well as the protection and safeguarding of critical habitat and habitat corridors to address population fragmentation. Urgent adoption of these recommendations is required, and the novel information generated by this research provides the evidential basis for their effective implementation that will help ensure the long-term persistence of the Arabian leopard.

description: Our topic concerns a long standing puzzle: the energy of gravitating systems. More precisely we want to consider, for gravitating systems, how to best describe energy-momentum and angular momentum/center-of-mass momentum (CoMM). It is known that these quantities cannot be given by a local density. The modern understanding is that (i) they are quasi-local (associated with a closed 2-surface), (ii) they have no unique formula, (iii) they have no reference frame independent description. In the first part of this work we review some early history, much of it not so well known, on the subject of gravitational energy in Einstein's general relativity (GR), noting especially Noether's contribution. In the second part we review (including some new results) much of our covariant Hamiltonian formalism and apply it to Poincaré gauge theories (GR is a special case). The key point is that the Hamiltonian boundary term has two roles, it determines the quasi-local quantities, and, furthermore it determines the boundary conditions for the dynamical variables. Energy-momentum and angular momentum/CoMM are associated with the geometric symmetries under Poincaré transformations. They are best described in a local Poincaré gauge theory. The type of spacetime that naturally has this symmetry is Riemann-Cartan spacetime, with a metric compatible connection having, in general, both curvature and torsion. Thus our expression for the energy-momentum of physical systems is obtained via our covariant Hamiltonian formulation applied to Poincaré gauge theories.

description: In this paper, we investigate imaginary part of the potential for a moving quarkonia in plasma. In order to verify the validity of imaginary part of the potential we employ hyperscaling violation metric background. In QCD system the imaginary part of potential shows the decay behaviour and the corresponding potential should be negative. The corresponding potential always appears in QCD as an exponential function. We find general constraints for Im$V_{Q\bar{Q}}$ at the near horizon limit and apply them for some known cases. Finally, we find the suitable spatial dimension d, z and $θ$ also rapidity $η$ for two interesting cases. Our calculation with AdS/CFT guarantees the dynamical parameter as a $θ$ in hyperscaling violation metric background. We also present the hyperscaling violationg metric in this context very close to YM theory with finite temperature.

description: Exoplanets orbiting close to their parent stars could lose some fraction of their atmospheres because of the extreme irradiation. Atmospheric mass loss primarily affects low-mass exoplanets, leading to suggest that hot rocky planets might have begun as Neptune-like, but subsequently lost all of their atmospheres; however, no confident measurements have hitherto been available. The signature of this loss could be observed in the ultraviolet spectrum, when the planet and its escaping atmosphere transit the star, giving rise to deeper and longer transit signatures than in the optical spectrum. Here we report that in the ultraviolet the Neptune-mass exoplanet GJ 436b (also known as Gliese 436b) has transit depths of 56.3 +/- 3.5% (1 sigma), far beyond the 0.69% optical transit depth. The ultraviolet transits repeatedly start ~2 h before, and end >3 h after the ~1 h optical transit, which is substantially different from one previous claim (based on an inaccurate ephemeris). We infer from this that the planet is surrounded and trailed by a large exospheric cloud composed mainly of hydrogen atoms. We estimate a mass-loss rate in the range of ~10^8-10^9 g/s, which today is far too small to deplete the atmosphere of a Neptune-like planet in the lifetime of the parent star, but would have been much greater in the past.

description: Six million Americans are living with heart failure and this number is expected to increase by 46% within the next 15 years.  Surgically implanted mechanical pumps [Ventricular Assist Devices (VADs)] are becoming a more common treatment for end stage heart failure.  However, there is limited research on the patient experience of living with a VAD. This study addresses the importance of self-image and body satisfaction for post-VAD psychological health.       This study utilized a mixed-methods approach to analyze the relationship between body image, age, sex, and ethnicity. Participants were 51 men and 14 women, with ages ranging from 20-83 years old.  Findings strongly suggested body image as a relevant factor in post-operative quality of life, as 58% of participants indicated experiencing VAD-related body image concerns.  Post hoc qualitative analysis found that when asked about general VAD-related stressors, 40% of participants mentioned factors relevant to body image and physical self-concept. Thematic analysis found that participants’ accounts centered around the following themes: Body Appearance, Physical Burden and Limited Freedom to Move, Physical Changes in Self-Identity, and Body Integrity. Recommendations are made for professionals working with VAD patients.

description: Interactions generically have important effects on the topological quantum phases. For a quantum anomalous Hall (QAH) insulator, the presence of interactions can qualitatively change the topological phase diagram which, however, is typically hard to measure in the experiment. Here we propose a novel scheme based on quench dynamics to detect the mean-field topological phase diagram of an interacting Chern insulator described by QAH-Hubbard model, with nontrivial dynamical quantum physics being uncovered. We focus on the dynamical properties of the system at a weak to intermediate Hubbard interaction which mainly induces a ferromagnetic order under the mean-field level. Remarkably, three characteristic times $t_s$, $t_c$, and $t^*$ are found in the quench dynamics. The first two capture the emergence of dynamical self-consistent particle density and dynamical topological phase transition respectively, while the last one gives a linear scaling time on the topological phase boundaries. A more interesting result is that $t_s>t^*>t_c$ ($t^*

description: Economic Load Dispatch (ELD) is one of the essential components in power system control and operation. Although conventional ELD formulation can be solved using mathematical programming techniques, modern power system introduces new models of the power units which are non-convex, non-differentiable, and sometimes non-continuous. In order to solve such non-convex ELD problems, in this paper we propose a new approach based on the Social Spider Algorithm (SSA). The classical SSA is modified and enhanced to adapt to the unique characteristics of ELD problems, e.g., valve-point effects, multi-fuel operations, prohibited operating zones, and line losses. To demonstrate the superiority of our proposed approach, five widely-adopted test systems are employed and the simulation results are compared with the state-of-the-art algorithms. In addition, the parameter sensitivity is illustrated by a series of simulations. The simulation results show that SSA can solve ELD problems effectively and efficiently.
