The Mediating Role of Perceived Stress and Academic Procrastination between Physical Activity and Depressive Symptoms among Chinese College Students during the COVID-19 Pandemic

Depressive symptoms, a prevalent mood illness, significantly harm college students’ physical and mental health. Individuals have experienced some degree of psychological harm as a result of the COVID-19 pandemic. Taking this into account, the purpose of this study was to investigate the relationship between physical activity (PA) and depressive symptoms among college students during the COVID-19 pandemic, as well as the mediating roles of perceived stress and academic procrastination. A total of 586 college students were subjected to the Physical Activity Scale (PARS-3), the Perceived Stress Scale (PSS-10), the Procrastination Assessment Scale-Students (PASS), and the Patient Health Questionnaire (PHQ-9). Findings from this research demonstrated that there was a significant positive correlation between perceived stress, academic procrastination, and depressive symptoms, while PA was significantly negatively correlated with perceived stress, academic procrastination, and depressive symptoms. The results of the chain mediation analysis showed that PA had a significant direct effect on depressive symptoms. Perceived stress, academic procrastination, and perceived stress-academic procrastination had significant mediating and chain mediating effects on the relationship between PA and depressive symptoms. In conclusion, PA among college students during the COVID-19 pandemic affects their depressive symptoms directly and indirectly through the independent mediating effect of perceived stress and academic procrastination, as well as the chain mediating effect of perceived stress and academic procrastination.
Ripple induced fast ion loss and related effects in JT-60U

Experiments have been carried out in JT-60U to verify the modelling of fast ion ripple transport. The ripple induced loss was estimated from the neutron decay following neutral beam pulse injection and the loss related heat load on the first wall. Comparison of the lost fraction and the hot spot positions between measurements and orbit following Monte Carlo calculations exhibited good agreement, indicating that the ripple transport governing fast ion losses is explained within the framework of existing theory. Neutral beam heating experiments in JT-60U also indicate that H modes free of ELMs are still obtainable for ripple amplitudes of up to 2.2%
The Predictors of Unsafe Behaviors among Nuclear Power Plant Workers: An Investigation Integrating Personality, Cognitive and Attitudinal Factors

Unsafe behaviors, such as violations and human errors, have long been recognized as the main causes of accidents in nuclear power plants (NPPs). However, personal factors that influence unsafe behaviors among NPP workers have not been well examined, especially in an integrated model. This study proposes an integrated contextual mediated model to examine personality, cognitive and attitudinal predictors of unsafe behaviors among commissioning workers at NPPs. The model was verified using structural equation modeling technique with survey data from 177 commissioning workers in two Chinese NPPs. Results show that personality traits (i.e., conscientiousness, neuroticism, openness and agreeableness), executive function and safety attitudes exerted significant effects on unsafe behaviors. In addition, the effects of agreeableness and executive function were partly mediated by safety attitudes. Both conscientiousness and neuroticism indirectly influenced unsafe behaviors through the mediating role of executive function. The findings shed light on the design of evidence-based interventions for safety performance in NPPs.
TDFCAM: A method for estimating stable isotope trophic discrimination in wild populations

Abstract Stable isotope mixing models (SIMMs) are widely used for characterizing wild animal diets. Such models rely upon using accurate trophic discrimination factors (TDFs) to account for the digestion, incorporation, and assimilation of food. Existing methods to calculate TDFs rely on controlled feeding trials that are time‐consuming, often impractical for the study taxon, and may not reflect natural variability of TDFs present in wild populations. We present TDFCAM as an alternative approach to estimating TDFs in wild populations, by using high‐precision diet estimates from a secondary methodological source—in this case nest cameras—in lieu of controlled feeding trials, and provide a framework for how and when it should be applied. In this study, we evaluate the TDFCAM approach in three datasets gathered on wild raptor nestlings (gyrfalcons Falco rusticolus; peregrine falcons Falco perigrinus; common buzzards Buteo buteo) comprising contemporaneous δ13C & δ15N stable isotope data and high‐quality nest camera dietary data. We formulate Bayesian SIMMs (BSIMMs) incorporating TDFs from TDFCAM and analyze their agreement with nest camera data, comparing model performance with those based on other relevant TDFs. Additionally, we perform sensitivity analyses to characterize TDFCAM variability, and identify ecological and physiological factors contributing to that variability in wild populations. Across species and tissue types, BSIMMs incorporating a TDFCAM outperformed any other TDF tested, producing reliable population‐level estimates of diet composition. We demonstrate that applying this approach even with a relatively low sample size (n < 10 individuals) produced more accurate estimates of trophic discrimination than a controlled feeding study conducted on the same species. Between‐individual variability in TDFCAM estimates for ∆13C & ∆15 N increased with analytical imprecision in the source dietary data (nest cameras) but was also explained by natural variables in the study population (e.g., nestling nutritional/growth status and dietary composition). TDFCAM is an effective method of estimating trophic discrimination in wild animal populations. Here, we use nest cameras as source dietary data, but this approach is applicable to any high‐accuracy method of measuring diet, so long as diet can be monitored over an interval contemporaneous with a tissue's isotopic turnover rate.
Association between Experiences in Life and Quality of Life among Lebanese University Students in a Collapsing Country: The Moderating Role of Religious Coping and Positivity

(1) Background: No goal can be more important than optimal individual quality of life (QOL); life experiences, religious coping, and positivity play pivotal roles in achieving this goal. The aim is to assess the correlation between positive/negative experiences in life and QOL, taking into consideration the moderating role of positivity and positive/negative religious coping among a sample of Lebanese university students. (2) Methods: This cross-sectional study was carried out between November and December 2021, and enrolled 333 university students, aged between 18 and 30 years, from various areas in Lebanon’s governorates. The 12-item Short Form Health Survey, the brief religious coping methods scale, and the Scale of Positive and Negative Experience were included in the questionnaire. Forward linear regressions were conducted to check for correlates associated with physical and mental QOL scores. All variables that showed a correlation or effect size > |0.24| were entered in the multivariable and moderation models as independent ones. Significance was set at a p < 0.05. (3) Results: A linear regression, taking the physical QOL score as the dependent variable, showed that living in rural areas compared to urban and more positivity were significantly associated with a better physical QOL, whereas more negative religious coping was significantly associated with a lower physical QOL. More positivity and more positive religious coping were significantly associated with a better mental QOL. The moderation analysis showed that in people with high positive experiences, those with higher negative religious coping had lower mental QOL. (4) Conclusions: In a society as deeply religious as Lebanon, it is crucial to organize awareness programs to help in discriminating between religious coping mechanisms. Across order to stop further detrimental effects on QOL, our findings may serve as a solid foundation for future studies of QOL with additional variables, in other groups and nations.
The Past and Present Lives of the Intraocular Transmembrane Protein CD36

Cluster of differentiation 36 (CD36) belongs to the B2 receptors of the scavenger receptor class B family, which is comprised of single-chain secondary transmembrane glycoproteins. It is present in a variety of cell types, including monocytes, macrophages, microvascular endothelial cells, adipocytes, hepatocytes, platelets, skeletal muscle cells, kidney cells, cardiomyocytes, taste bud cells, and a variety of other cell types. CD36 can be localized on the cell surface, mitochondria, endoplasmic reticulum, and endosomes, playing a role in lipid accumulation, oxidative stress injury, apoptosis, and inflammatory signaling. Recent studies have found that CD36 is expressed in a variety of ocular cells, including retinal pigment epithelium (RPE), retinal microvascular endothelial cells, retinal ganglion cells (RGC), Müller cells, and photoreceptor cells, playing an important role in eye diseases, such as age-related macular degeneration (AMD), diabetic retinopathy (DR), and glaucoma. Therefore, a comprehensive understanding of CD36 function and downstream signaling pathways is of great significance for the prevention and treatment of eye diseases. This article reviews the molecular characteristics, distribution, and function of scavenger receptor CD36 and its role in ophthalmology in order to deepen the understanding of CD36 in eye diseases and provide new ideas for treatment strategies.
Relation between Shyness and Music Academic Engagement: The Mediation of Achievement Goals—A Cross-Sectional Survey Study

Music discipline that emphasizes expression, performance and collaboration may cause difficulties for shy students who are prone to anxiety about social interaction, which might cause low music academic engagement and achievement. According to Models of Personality and Affect regarding the role of psychological constructs in educational contexts, shyness and academic engagement are the first and third-level variables, respectively. We hypothesized that achievement goals might be the second-level variable between shyness and academic engagement. Two hypotheses were proposed in the study: (1) shyness is negatively related to music academic engagement; (2) the music achievement goals mediate shyness and music academic engagement. The research was conducted in May 2022. A total of 515 college students who major in music were randomly recruited from a public university in Shanxi province, China. A 20 min self-report questionnaire was conducted as the data collection method. The research results revealed the following: (1) shyness was negatively associated with musical academic engagement; (2) the music mastery goals and the music performance avoidance goals (excluding the performance approach goal) partially mediated the association between shyness and music academic engagement in music learning. These findings have implications for the research and practice of music academic engagement of shyness.
Diet composition and selection of Père David's deer in Hubei Shishou Milu National Nature Reserve, China

Abstract Hubei Shishou Milu National Nature Reserve is an ideal place to restore the wild population of Père David's deer (Elaphurus davidianus). Understanding foraging ecology and diet composition is essential for assessing population development or establishing long‐term effective conservation measures for endangered species. However, little is known about the diet composition of Père David's deer and its diet selection mechanism. In this study, we used stable isotope technology to investigate the diet composition of Père David's deer according to various tissues (i.e., fur, muscle, liver, heart, and feces) and seasons, and evaluated the correlation between the nutrient composition of plants and diet composition. Bayesian isotope analysis showed that the autumn and winter diet estimated by fur and fecal samples indicated a diet dominated by C3 grasses (42.7%–57.2%, mean), while the summer diet estimated by muscle and liver samples was dominated by C3 forbs (30.9%–41.6%, mean). The Pearson correlation test indicated that the contribution of winter diet composition reflected by fur and fecal samples was associated with correlations with crude protein (r = .666, p < .01) and soluble sugars (r = .695, p < .01). The results indicated that crude protein and soluble sugars were important factors influencing the winter diet selection of Père David's deer. In the context of the current reintroduction facing many challenges, such as habitat fragmentation, wetland degradation, and human disturbance, comprehensively evaluating the diet selection mechanism of Père David's deer under different resource specificities and temporal changes should be considered in the future.
Phage‐resistant mutations impact bacteria susceptibility to future phage infections and antibiotic response

Abstract Bacteriophage (phage) therapy in combination with antibiotic treatment serves as a potential strategy to overcome the continued rise in antibiotic resistance across bacterial pathogens. Understanding the impacts of evolutionary and ecological processes to the phage‐antibiotic‐resistance dynamic could advance the development of such combinatorial therapy. We tested whether the acquisition of mutations conferring phage resistance may have antagonistically pleiotropic consequences for antibiotic resistance. First, to determine the robustness of phage resistance across different phage strains, we infected resistant Escherichia coli cultures with phage that were not previously encountered. We found that phage‐resistant E. coli mutants that gained resistance to a single phage strain maintain resistance to other phages with overlapping adsorption methods. Mutations underlying the phage‐resistant phenotype affects lipopolysaccharide (LPS) structure and/or synthesis. Because LPS is implicated in both phage infection and antibiotic response, we then determined whether phage‐resistant trade‐offs exist when challenged with different classes of antibiotics. We found that only 1 out of the 4 phage‐resistant E. coli mutants yielded trade‐offs between phage and antibiotic resistance. Surprisingly, when challenged with novobiocin, we uncovered evidence of synergistic pleiotropy for some mutants allowing for greater antibiotic resistance, even though antibiotic resistance was never selected for. Our results highlight the importance of understanding the role of selective pressures and pleiotropic interactions in the bacterial response to phage‐antibiotic combinatorial therapy.
Weighted Breslow-type and maximum likelihood estimation in semiparametric transformation models

A semiparametric transformation model comprises a parametric component for covariate effects and a nonparametric component for the baseline hazard/intensity. The Breslow-type estimator has been proposed for estimating the nonparametric component in some inefficient estimation procedures. We show that introducing weights into this estimator leads to nonparametric maximum likelihood estimation, with the weights depending on the martingale residuals. The weighted Breslow-type estimator suggests an iterative reweighting algorithm for nonparametric maximum likelihood estimation, which can be implemented by a weighted variant of the existing algorithms for inefficient estimation, and can be computationally more efficient than an em -type algorithm. The weighting idea is further extended to semiparametric transformation models with mismeasured covariates. Copyright 2009, Oxford University Press.
Properties of Sharav (Khamsin) Dust–Comparison of Optical and Direct Sampling Data

Abstract Simultaneous measurements of optical depth and Size distribution in a dust storm are presented. The measured and derived properties of the aerosol are compared with each other and with other results published in the scientific literature. We observe some global commonality in the measured size spectra of desert aerosols especially for post-frontal conditions. On the other hand, during the passage of the front itself, high aerosol concentrations with a sharp peak in radius at −1 μm were observed. Generally, these were not similar to other size distributions reported in the literature. The imaginary part of the refractive index in the spectral region 0.3-1.7 μm was found to be similar to that found in other deserts. Comparison of the optical measurements with the direct sampling data suggests that the general time trends of the size distributions, as measured in situ, are followed by the optical depth and its variations with wavelength. On the other hand, detailed short-term fluctuations detected b.
Propagating surface plasmon resonances in two-dimensional patterned gold-grating templates and surface enhanced Raman scattering

Surface enhanced Raman scattering (SERS) from Raman active rhodamine-6G probe molecules is investigated on two-dimensional patterned gold-grating templates having submicron periodicity of 800 nm. Two-dimensional surface nano-patterning in the form of square, hexagonal, and rectangle has been obtained through cost effective laser interference lithography. We find a reproducible SERS enhancement of the order of 105 on these nano-patterned plasmonic templates, showing a slight superior result on hexagonal patterned templates. Strong localized near-fields due to surface plasmon resonance (SPR) lead to such an enhancement. We find evidence for good correlation in the SPR excitation and enhanced Raman scattering through experimental investigation by using different Raman pump excitation wavelengths of 785 nm, 633 nm, and 514 nm and different pump powers. The results are strongly supported by computer simulations of the electromagnetic fields at the pump wavelengths. Our results demonstrate that an optimized sel.
Dynamic force balance model for metal transfer analysis in arc welding

A dynamic force balance model is proposed by introducing the inertial force to predict metal transfer in arc welding. The dynamics of the pendant drop is modelled as a linear time-varying second-order system and the spring constant and electromagnetic force are calculated for the ellipsoidal drop. Two methods are employed to estimate the spring constant: numerical calculation for the ellipsoidal drop and a closed-form equation for the spherical drop at equilibrium. The inertial force is produced by drop oscillation and it is applied to the drop-detaching criterion. Since the inertial force reaches half the electromagnetic force at the transition current, it influences drop detachment with current increase. The proposed dynamic force balance model predicts the resonance frequency and detaching drop size with reasonable accuracy.
Insights into efficacy and safety of dapagliflozin treatment for the management in older adults with type 2 diabetes: a systematic review and meta-analysis

ABSTRACT Background This study aimed to evaluate the efficacy and safety of dapagliflozin as a monotherapy glucose-lowering drug treatment for older adults with diabetes. Research Design & Methods Randomized controlled trial reports were retrieved from PubMed, Embase Cochrane Library, and Web of Science from database inception to 8 May 2021. Publication bias and heterogeneity were assessed using the Cochrane risk-of-bias tool and the Cochrane Q statistic, respectively. Results Compared with placebo, dapagliflozin as a monotherapy glucose-lowering drug did improve the control of glycosylated hemoglobin and fasting plasma glucose levels in older adults. Our analysis also confirmed that the body weight of older adults was well controlled under treatment of dapagliflozin as a monotherapy glucose-lowering drug. Patients in older adults with diabetes took a higher risk of genital infection and renal impairment or failure after treatment of dapagliflozin. In addition, treatment with dapagliflozin reduced the risk of hypoglycemia, and did not reveal increased risk of urinary tract infection and developing fractures compared to placebo in older adults. Conclusions Dapagliflozin as a monotherapy glucose-lowering drug appeared to be an effective treatment for older adults with diabetes, although it might increase risk of genital infection and renal impairment or failure.
Impacts of Satellite-Observed Winds and Total Precipitable Water on WRF Short-Range Forecasts over the Indian Region during the 2006 Summer Monsoon

Abstract Assimilation experiments have been performed with the Weather Research and Forecasting (WRF) model’s three-dimensional variational data assimilation (3DVAR) scheme to assess the impacts of NASA’s Quick Scatterometer (QuikSCAT) near-surface winds, and Special Sensor Microwave Imager (SSM/I) wind speed and total precipitable water (TPW) on the analysis and on short-range forecasts over the Indian region. The control (without satellite data) as well as WRF 3DVAR sensitivity runs (which assimilated satellite data) were made for 48 h starting daily at 0000 UTC during July 2006. The impacts of assimilating the different satellite dataset were measured in comparison to the control run, which does not assimilate any satellite data. The spatial distribution of the forecast impacts (FIs) for wind, temperature, and humidity from 1-month assimilation experiments for July 2006 demonstrated that on an average, for 24- and 48-h forecasts, the satellite data provided useful information. Among the experiments, WR.
The diagnosis, natural history, and management of von Willebrand disease in women in the age of guidelines

ABSTRACT Introduction Women and girls with bleeding disorders face multiple bleeding challenges throughout their life. The most significant morbidity and mortality are due to heavy menstrual bleeding and postpartum hemorrhage in their reproductive years. The ASH/ISTH/NHF/WFH 2021 guidelines on diagnosing and managing von Willebrand disease (VWD) provide several new updates. Areas covered Women with VWD have a higher prevalence of heavy menstrual bleeding. The subpopulation of adolescents is particularly vulnerable, as the diagnosis is often delayed with increased comorbidity of iron deficiency anemia and associated symptoms. A detailed review is done on the prevalence of bleeding-related complications, especially heavy menstrual bleeding (HMB) and post-partum hemorrhage (PPH). The management strategies are also reviewed in detail, with a specific focus on the target factor levels and the use of antifibrinolytics. Expert opinion The 2021 ASH/ISTH/NHF/WFH diagnostic and management recommendations are reviewed with a specific focus on hormonal methods of HMB management and antifibrinolytics in this situation. The reviewed topics include neuraxial anesthesia, factor cutoff, and tranexamic acid use in the postpartum period.
Symbolic computation of stiffness matrices for quadratic triangular elements

Conditions under which it is possible to determine exact integrals for stiffness matrix entries for a 6-noded isoparametric plane strain element have been investigated. Considerable use has been made of the algebraic manipulation language MAPLE in obtaining the results. It has been shown that exact integration can be performed when the Jacobian becomes a degenerate quadratic and in some other cases. A precise algebraic condition has been found for the degenerate case and related to the geometry of the element. Copyright © 1999 John Wiley & Sons, Ltd.
