Authors: Zhang Hao , Qiao Mengying , Liu Xiangju , Wang Youqiang , Duan Jizhou 
Published: October 2024

AbstractLaser cladding technology is an advanced surface modification technique that has gained significant attention in various fields due to its energy savings, efficiency, and environmental friendliness. This paper discusses the preparation of AlCoCrFeNi high‐entropy alloy (HEA) coatings on the surface of a 5083 aluminum alloy using laser cladding technology under the Ar gas conditions. An orthogonal test system was used to optimize the laser cladding process parameters. The microstructure, as well as the mechanical, frictional, and electrochemical properties of the HEA coatings, were comparatively analyzed under the two process conditions S4 and S10. The results indicate that, under S10, the HEA coatings exhibit optimal surface quality. The coatings contained a mixture of Face‐centered cubic (FCC) and Body‐centered cubic (BCC) phases. Microscopic examination revealed three distinct areas: dark, gray, and off‐white. The coatings can significantly improve the wear and corrosion resistance of the alloy substrate. For the best results, it is set the laser power to 200 W, the laser scanning distance to .05 mm, and the laser scanning rate to 1250 mm/s. This present study offers a novel technical foundation for the fabrication of HEA coatings.

Published: October 2024

AbstractPorous mullite ceramics were synthesized via ceramic processing using a local industrial kaolin, alumina, and with AlF3 and MoO3 precursor additives to catalyze the formation of pores and acicular mullite grains. The textural properties, crystalline phases, microstructures, and mechanical properties of the obtained samples were comprehensively analyzed and compared with a reference mullite formulated without additives. The obtained ceramics have a well‐defined porous microstructure, with a porosity of about 50%, and a pore size distribution in the 0.1–2 µm range. Ceramics that involve the addition of MoO3 present well‐defined acicular mullite grains, with slightly higher porosity, larger pores, and better mechanical resistance compared to those processed using AlF3.To correlate the ceramic porosity with its mechanical properties, a simple model of spherical pores was proposed to assess the flexural strength of the dense ceramic. It was found that the inclusion of additives promoting needle‐like microstructures increases the mechanical resistance up to four times the value determined for the ceramic without additives (flexural strength up to 390 MPa for zero‐porosity extrapolation). These results, together with the refractoriness of mullite, allow inferring the potential applications of the developed materials as structural ceramics with relatively low density and for filtering applications.
Social media profiling: The influence of personal and professional social media content on hiring ratings
Authors: Hartwell Christopher J. , Harrison Jake T. , Campion Michael A. 
Published: October 2024

AbstractThis study integrates identity and situational strength theories into a realistic accuracy model framework to develop and test hypotheses regarding how hiring managers perceive social media (SM) information, and how those perceptions translate into ratings. In Study 1, 310 h professionals rated which SM content they perceive as most useful in assessing applicants on various work‐related constructs. The provided a foundation for Study 2, where 151 h professionals participated in an experimental hiring simulation to understand whether these perceptions of SM information translate into rating behavior. Results indicate that manipulating SM content influenced HR professionals’ ratings of applicants. Non‐job‐related SM content influenced ratings of work‐related constructs more strongly than job‐related content. Professional SM was rated more favorably than personal SM.
Improving the Use of Sensory Approaches in an Acute Inpatient Mental Health Unit Using a Co‐Designed Multifaceted Implementation Strategy
Authors: Wright Lisa , Meredith Pamela , Bennett Sally , Doig Emmah 
Published: October 2024

ABSTRACTDespite the therapeutic benefits of sensory approaches being well documented, little research has focused on improving their implementation in acute mental health units. The use of implementation frameworks to improve the use of evidence‐based practices has shown promising results in healthcare; however, there is little evidence for their use in acute mental health units. A pre–post comparison design was used to determine the effect of an 11‐month co‐designed theory‐informed multifaceted implementation strategy on the use of sensory approaches and the use of seclusion/restraint in one acute mental health ward. This study was guided by Integrated Knowledge Translation (IKT) and informed by the Behaviour Change Wheel (BCW) approach. Implementation strategies were co‐designed and included provision of sensory materials/resources; education/training; prompts/reminders; modelling; audit and feedback; workplace coalition; and facilitation. Data were collected through pre‐ and post‐project questionnaires (pre‐ n = 37, post‐ n = 40) and routine clinical data. Data were analysed using SPSS and thematic analysis. Data for matched pairs (n = 19) revealed significant improvements between pre‐ and post‐perceived levels of knowledge and confidence in using sensory approaches. Significant increases were found in the use of sensory kits, weighted modalities and sensory assessment/plans. Post participants' recommendations to sustain the use of sensory approaches in their unit included ongoing training; funding; maintenance and supply of sensory equipment; increased staffing; and support from colleagues. This is the first study to use the IKT and BCW to design, facilitate and evaluate a co‐designed, theory‐informed implementation strategy to improve the use of sensory approaches in an acute mental health unit.
Do retail investors gamble more during lockdown?
Authors: Pavabutr Pantisa , Zhao Bin 
Published: October 2024

AbstractRetail investors are known to favor stocks with lottery‐like features and trade too much. Less is known about their intertemporal demand and risk‐taking behavior in lottery‐type stocks. We use intraday transaction data between September 2019 and June 2020 from the Stock Exchange of Thailand to test how individual's risk attitude changes with respect to decline in their wealth prospects during the COVID‐19 lockdown. The behavior of the investors supports a reference dependent preference. Confronted with lowered wealth prospects, retail investors substantially reduce their underweighting in nonlottery stocks while increasing overweighting and turnover frequency in lottery stocks resulting in deteriorating portfolio performance.

Published: October 2024

ABSTRACTAlthough observational studies have linked primary aldosteronism (PA) with cardiovascular diseases (CVDs), the causality remains uncertain. In this study, we aimed to investigate whether PA is causally associated with CVD risk and cardiac magnetic resonance (CMR) parameters using the Mendelian randomization (MR) method. Independent and genome‐wide significant single nucleotide polymorphisms for PA were extracted from genome‐wide association study (GWAS) summary statistics. Genetic associations with the CVDs and CMR parameters were obtained from recent large‐scale GWASs or genetic consortia. Inverse‐variance weighted (IVW) method was utilized for the preliminary estimates, and multiple sensitivity analyses (including weighted median, Cochran's Q test, MR‐Egger, MR‐PRESSO, and leave‐one‐out analysis) were conducted to verify the robustness of the results. The MR analyses using the IVW method showed that genetically predicated PA was significantly associated with atrial fibrillation (OR = 1.046, 95% CI: 1.029–1.062, padj < 0.001), myocardial infarction (OR = 1.029, 95% CI: 1.005–1.053, padj = 0.027), heart failure (OR = 1.023, 95% CI: 1.004–1.042, padj = 0.027), any stroke (OR = 1.062, 95% CI: 1.031–1.095, padj < 0.001), any ischemic stroke (OR = 1.058, 95% CI: 1.022–1.095, padj = 0.004), and small vessel stroke (OR = 1.116, 95% CI: 1.041–1.196, padj = 0.004). Notably, PA also had a causal effect on adverse cardiac remodeling, including larger ventricular and atrial volumes, higher ventricular stroke volume, and reduced left atrial emptying fraction. Our findings support a causal role of PA in higher cardiovascular disease risk and adverse cardiac remodeling. Given the diagnostic delay and disease burden in PA, more attention should be paid to the screening and treatment of PA to reduce the incidence of cardiovascular outcomes.
What is the probability that higher versus lower quality of evidence represents true effects estimates?

Published: October 2024

AbstractRationale, Aims, and ObjectivesThe previous studies demonstrated that the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, a leading method for evaluating the certainty (quality) of scientific evidence (CoE), cannot reliably differentiate between various levels of CoE when the objective is to accurately assess the magnitude of the treatment effect. An estimated effect size is a function of multiple factors, including the true underlying treatment effect, biases, and other nonlinear factors that affect the estimate in different directions. We postulate that non‐weighted, simple linear tallying can provide more accurate estimates of the probability of a true estimate of treatment effects as a function of CoE.MethodsWe reasoned that stable treatment effect estimates over time indicate truthfulness. We compared odds ratios (ORs) from meta‐analyses (MAs) before and after updates, hypothesising that a ratio of odds ratios (ROR) equal to 1 will be more commonly observed in higher versus lower CoE. We used a subset of a previously analysed data set consisting of 82 Cochrane pairs of MAs in which CoE has not changed with the updated MA. If the linear model is valid, we would expect a decrease in the number of ROR = 1 cases as we move from high to moderate, low, and very low CoE.ResultsWe found a linear relationship between the probability of a potentially ‘true’ estimate of treatment effects as a function of CoE (assuming a 10% ROR error margin) (R2 = 1; p = 0.001). The probability of potentially ‘true’ estimates decreases by 21% (95% CI: 18%–24%) for each drop in the rating of CoE. A linear relationship with a 5% ROR error margin was less clear, likely due to a smaller sample size. Still, higher CoE showed a significantly greater probability of ‘true’ effects (53%) compared to non‐high (i.e., moderate, low, or very low) CoE (25%); p = 0.032.ConclusionThis study confirmed linear relationship between CoE and the probability of potentially ‘true’ estimates. We found that the probability of potentially “true” estimates decreases by about 20% for each drop in CoE (from about 80% for high to 55% for moderate to 35% to low and 15% to very low CoE).

AbstractAimTo investigate the effect of preadmission education given to laparoscopic sleeve gastrectomy patients on preoperative and postoperative anxiety, postoperative pain, and patient vital signs.MethodsThe study was designed as randomized, controlled, experimental, and single‐blind. This study was conducted with 68 patients who met the inclusion criteria and underwent laparoscopic sleeve gastrectomy in the general surgery clinic of a university hospital between December 2022 and October 2023. Data were collected using the ‘Perioperative Form,’ ‘Visual Analog Scale,’ and ‘State Anxiety Scale I‐II.’ Intervention group patients were informed and educated about the surgical process in the outpatient clinic. The anxiety levels of all patients were determined with the State Anxiety Scale the day before surgery. In the postoperative period, vital signs (once), anxiety (on the first day after surgery), and pain levels (eight times during 48 h) were measured.ResultsIn the analysis between the groups, the difference between the duration of postoperative hospital stay (p = 0.007), pain (p = 0.000 for all measured), and anxiety levels (p = 0.000) was statistically significant. There were also significant differences in the diastolic blood pressure (p = 0.007), body temperature (p = 0.000), and saturation values (p = 0.000). Patients' readiness level for surgery was the most influential factor in postoperative pain levels (p = 0.000).ConclusionThe education given to the patients before hospitalization decreased preoperative and postoperative anxiety levels, postoperative hospital stay and pain levels, and positively affected diastolic blood pressure, body temperature and saturation levels. One‐to‐one education given to patients in the outpatient clinic also contributes positively to their readiness for surgery. This study provides valuable evidence to the wider global clinical community by demonstrating the important benefits of preadmission education for patients undergoing bariatric surgery. Implementation of similar educational interventions in diverse healthcare settings worldwide may lead to increased postoperative recovery and improved overall patient well‐being after bariatric surgery.

Published: October 2024

AbstractSince the 1980s, the European eel (Anguilla anguilla) has declined by over 90% in recruitment across its European and North African distribution area. This diadromous fish spawns at sea and migrates into continental waters, where it grows for three to more than 30 years, depending on habitat conditions and location. During their growth, different habitat use tactics can locally influence the life‐history traits of eels, including their survival rates. Thus, the spatio‐temporal dimension of this species is crucial for management. Based on a rare Mediterranean long‐term survey of more than 20 years (2001–2022) in an artificial drainage canal connected to a vast brackish lagoon (the Vaccarès lagoon), we aimed to study the dynamics of one subpopulation's life‐history traits. We used Bayesian multistate capture‐mark‐recapture (CMR) models to assess the temporal variability in survival and abundance at both seasonal and inter‐annual scales, considering life‐stage structure. High survival rates and low detection probabilities were found for the undifferentiated and female yellow stages. In contrast, female silver eels exhibited lower survival rates and higher capture probabilities. Estimating detection probabilities and survival rates enabled accurate assessment of relative abundance across different life stages and time periods. Our findings indicated a substantial decrease in the abundance of undifferentiated and female yellow eels in the early 2000s, whereas the abundance of female silver eels remained consistently low yet stable throughout the study period. Considering the life stage seemed essential to study the dynamics of the eel during its continental growing period. The present results will provide key elements to propose and implement suitable sustainable environmental management strategies for eel conservation.
Responses to sound in three Centrarchid species: Do heterospecific interactions change behavior?
Authors: Bendig Taylor A. , Dycha Grace M. , Higgs Dennis M. 
Published: October 2024

AbstractDue to the increasing prevalence and variety of underwater anthropogenic noise sources, and the growing human population, anthropogenic noise has the potential to negatively impact aquatic organisms. With this growing threat, the question of how fishes respond to this stressor in their natural environments becomes more urgent. The current study used behavioral trials with bluegill sunfish Lepomis macrochirus, pumpkinseed sunfish Lepomis gibbosus, and rock bass Ambloplites rupestris, both in isolation and in a heterospecific trial, to determine how behaviors indicative of stress were influenced by interspecific interactions when exposed to recordings of pure tones and boat motors. Regardless of social context, all three species experienced an increase in fin beats per second, an increase in time spent at the bottom of the pen, and a decrease in time spent swimming when exposed to boat noise. Fishes in heterospecific trials experienced more fin beats per second and spent less time swimming, but there was no significant difference when comparing time spent at the bottom of pen with fish in individual trials. Our findings of behavioral changes when exposed to acoustic stimuli, in two social contexts, allow for a deeper understanding of interspecific effects and provide insight into how varied field studies can be useful in studying fish behavior when encountering acoustic stressors.
The influence of assistance in home‐based exercise programmes for individuals with intellectual disabilities
Authors: Noerr K. L. , Swinford R. 
Published: October 2024

AbstractBackgroundRegular physical activity (PA) decreases the risk of comorbidities associated with a sedentary lifestyle in individuals with intellectual disabilities (IDs). They also may experience additional barriers that may prevent PA, including access, proper instruction and support. At‐home PA programming is a feasible alternative to long‐term adherence. This study aimed to determine (1) how an at‐home DVD programme affects PA adherence and (2) the extent to which caregiver support influences PA.MethodsThirty‐one adolescent or adult‐aged participants with mild or moderate ID were randomised into a DVD or control group exercise intervention. Participants were given autonomy to choose what type of PA modality from the intervention they would like to participate in. Caregiver support during the PA was also measured.ResultsThe two‐way repeated‐measures MANOVA demonstrated that the intervention DVD group was statistically significant, with a large effect size in PA minutes (P = 0.014, ηP2 = 0.236) and rate of perceived exertion (P = 0.002, ηP2 = 0.342) compared with the control group.ConclusionsThe findings demonstrated that using an adapted DVD increased PA minutes and the rate of perceived exertion without high levels of caregiver support.

Published: October 2024

AbstractAstrocytes are the principle glial cells of the central nervous system and play an active role in maintaining proper metabolism in surrounding neurons. Because of their involvement in metabolic control, it is likely that their physiology changes in response to metabolic diseases such as diabetes and associated diabetic retinopathy. Here, we investigated whether microstructural changes in astrocyte morphology occur during the early stages of chronic hyperglycemia that may be indicative of early pathogenic programs. We used MORF3 mice in conjunction with streptozotocin‐induced hyperglycemia to investigate the morphology of single retinal astrocytes at an early timepoint in diabetic disease. We report that astrocytes initiate a morphological remodeling program, which depends on both the glycemic background and the presence of intravitreal injury, to alter the amount of the neuronal‐associated pad and bristle microstructural motifs. Additionally, hyperglycemia increases astrocyte uptake of cholera toxin B, possibly reflecting changes in glycolipid and glycoprotein biosynthesis. Chronic hyperglycemia coupled with intravitreal injection of cholera toxin B also causes extensive leukocyte infiltration into the retina. Our results have important clinical relevance as current therapies for diabetic retinopathy involve intravitreal injection of pharmaceuticals in individuals with often poorly controlled blood glucose levels.

Published: October 2024

AbstractThe functional signal of bone internal structure has been widely studied. Isolated form‐function relationships have often been assumed from the observation of presumed morphofunctional relationships, but have never been truly tested. Indeed, distinct bone microanatomical feature co‐evolve in response to various constraints that are difficult to detangle. This study tested for the first time the impact of various microanatomical parameters taken one by one, plus some in pairs, on bone strength under compression using biomechanical modelling. We carried out finite element analyses on humerus models, obtained from a white rhinoceros, with different heterogeneous internal structures, and analysed the magnitude and distribution of von Mises stresses. These tests validated earlier hypotheses of form‐function relationships about the greater resistance to compression provided by the thickening of the cortex and the filling of the medullary area by trabecular bone and highlighted the stronger impact of increasing trabecular bone compactness than of avoiding an open medullary cavity. By making it possible to estimate the relative impact of each parameter and of combinations of microanatomical features, they also showed the more limited impact of the trabecular bone compactness in the epiphyses to resist compression, and the fact that microanatomical changes of opposite but of similar amplitude impact can compensate each other, but that the impact of the sum of two negative microanatomical changes far exceeds the sum of the impacts of each of the two changes taken separately. These results contribute to a better understanding of bone adaptation and form‐function relationships so that they later can be used with confidence for palaeobiological inferences on fossil specimens, contributing to a better understanding of skeletal evolution during the evolutionary history of vertebrates. They also highlight the potential of taking internal structure into account in the bone biomechanical analyses. In addition, they can be used in bioinspiration to design resistant structures subjected to compression.
