Authors: Chiu Kenny , Stringaris Argyris , Leigh Eleanor 
Published: June 2024

AbstractBackgroundSocial anxiety disorder typically emerges in adolescence and its symptoms often co‐occur with depression and suicidal ideation. It is important to understand whether social anxiety symptoms precede depression and suicidal ideation in youth. This study aimed to investigate the temporal associations between baseline social anxiety and later suicidal ideation and depressive symptoms in a community youth sample.MethodsThe Wellcome Trust NSPN (Neuroscience in Psychiatry Network) study recruited 2397 youth aged 14–24 in the United Kingdom to participate in a prospective observational study. Participants were assessed for symptoms of social anxiety, generalised anxiety, depression and suicidal ideation at baseline, 1‐year follow‐up, and 2‐year follow‐up. We conducted multiple linear regression analyses and mediation analyses to examine whether baseline social anxiety was associated with 2‐year suicidal ideation and depressive symptoms (excluding suicide‐related items), and whether these associations were mediated by 1‐year depressive symptoms. The study was preregistered on the Open Science Framework.ResultsResults from multiple linear regression analyses indicated that baseline social anxiety symptoms were associated with 2‐year suicidal ideation (β = 0.07, p < 0.05, 95% CI [0.02, 0.12]) and 2‐year depressive symptoms (β = 0.08, p < 0.05, 95% CI [0.02, 0.13]), after controlling for baseline predicted variable. Furthermore, 1‐year depressive symptoms significantly mediated the relationship between baseline social anxiety symptoms and 2‐year suicidal ideation (β = 0.04, 95% CI [0.02, 0.05]), and the relationship between baseline social anxiety symptoms and 2‐year depressive symptoms (β = 0.06, 95% CI [0.03, 0.08]) after adjusting for age, sex, and other covariates.ConclusionsWe found evidence that baseline social anxiety symptoms were associated with 2‐year suicidal ideation and 2‐year depressive symptoms via 1‐year depressive symptoms in non‐clinical adolescents. These results may have important implications for targeted psychological interventions.

Authors: Moradi Seyed Ali Hosseini , Ghobadi Nader 
Published: June 2024

AbstractHere, NiFe2O4, MnFe2O4, and CoFe2O4 nanoferrites are prepared by coprecipitation synthesis technique from nickel, manganese, and cobalt chloride precursors. Synthesized nanoferrites are annealed by calcination process at 800°C for 2 h. To produce a novel anode electrode material for asymmetric supercapacitors (ASCs), the composite material of GO/NiFe2O4‐MnFe2O4‐CoFe2O4 is fabricated. Physicochemical aspects of the synthesized nanoferrites are evaluated. X‐ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and x‐ray photoelectron spectroscopy tests are conducted, respectively. The electrochemical activities are studied by cyclic voltammetry, glavanostatic charge–discharge, and electrochemical impedance spectroscopy (EIS) in 2 M KOH as the electrolyte. In three electrode system, the novel GO/NiFe2O4‐MnFe2O4‐CoFe2O4 electrode displays a high specific capacity of 325 C g−1 and preserves about 99.9% of its initial specific capacity. The GO/NiFe2O4‐MnFe2O4‐CoFe2O4//GO ASCs device is assembled using GO/NiFe2O4‐MnFe2O4‐CoFe2O4, GO, and 2 M KOH solution as the positive electrode, negative electrode, and electrolyte, respectively. Significantly, the GO/NiFe2O4‐MnFe2O4‐CoFe2O4//GO ASCs represent an outstanding energy density of 50.5 W h kg−1 at power density of 2560 W kg−1. Through the long‐term charge discharge cycling tests, this ASC device illustrates about 93.7% capacity retention after 3000 cycles. Then, the present study provides the NiFe2O4‐MnFe2O4‐CoFe2O4 composite nanoferrites as a novel favorable candidate for anode material.Research Highlights

AbstractTo evaluate the inflammatory tissue response to BioRoot™ RCS (BR) and AH Plus Jet (AHPJ) sealers implanted in mice subcutaneous tissue. It was hypothesized that the inflammatory tissue response to BR would be milder than to AHPJ. An in vivo study was carried out using isogenic mice. The sealers were implanted during standardized surgical procedures. The inflammatory response was evaluated by microscopic analysis and von Kossa reaction in the reactionary tissue around the specimens after 7, 21, and 63 days. For comparisons, a zinc oxide and eugenol sealer (ZOE) was used as a positive control, in addition to a negative control without a sealer (n = 10 per group/period). All statistical analyses considered a significance level of 5%. All endodontic sealers triggered an inflammatory tissue response after 7 days. BR had a higher inflammatory cell count and a thicker fibrous capsule when compared with AHPJ, but both were less inflammatory than ZOE (p < .001). After 21 days, BR continued to trigger an intense inflammatory tissue response, higher in both microscopic parameters compared to AHPJ, and a thicker fibrous capsule than ZOE (p < .001). After 63 days, the inflammatory tissue response decreased in BR, matching the fibrous capsule thickness with AHPJ and ZOE. BR promoted intense calcium precipitation in all study periods. After 63 days, AHPJ and BR sealers were more biocompatible to subcutaneous mice tissue, but AHPJ present better early inflammatory response, as well as BR showed potential bioactivity.Research Highlights
The inflammatory tissue response triggered by a bioceramic endodontic sealer (BR) was not milder than that triggered by an epoxy‐resin based endodontic sealer (AHPJ) during the first 3 weeks, considering the microscopic analysis of the reactionary tissue.
Acting authentically: Using play to cultivate authentic interrelating in role performance
Authors: Garrett Lyndon E. 
Published: June 2024

SummaryResearch is increasingly demonstrating that authenticity and human connection are fundamental and interrelated human needs. However, organizational roles often constrain authenticity and connection in workplace interactions, especially roles that are highly scripted. People want to feel authentic and connected at work, but they also need to adhere to role expectations. Organizational role scholars have long explored how roles cause feelings of inauthenticity, and more recently, the conditions that promote authenticity. We have limited understanding of how people approach being authentic in their roles without compromising or deviating from rigid role demands. To explore this, I conducted an inductive, qualitative study of six community theater productions, a context where roles are rigidly scripted, yet where actors strive to “live truthfully” within their fictional roles. I find that actors and directors work together to cultivate authentic interrelating in their roles, characterized by the combination of personal engagement and interpersonal attunement. This process involves engaging in different forms of play to move from mechanically learning their roles, to crafting personalized intentions, to ultimately transcending their roles, gradually increasing in vulnerability and responsiveness until they are able to experience authentic interrelating in their roles.

Published: June 2024

AbstractThis study investigates the variations in air–sea heat fluxes and temperatures in two ocean front regions, the Southwestern Atlantic Ocean (SWA) and the Drake Passage, widely recognized as hotspot areas with significant influences on South America weather and climate. We analyse means and trends of latent and sensible heat fluxes (LHF and SHF) and their associated air–sea temperatures (SAT and SST), based on monthly ERA5 (1985–2014) and eight CMIP6 models, for historical and long‐term simulations (2015–2099). The ERA5 trend for all parameters was positive over SWA, contrasting with the negative values observed in the Drake Passage, indicating surface warming and cooling, respectively. In the SWA, the ERA5 and CMIP6 multi‐model ensemble (MME) align in SST and SAT values, with a historical trend of 0.1°C·decade−1 and a significantly increasing trend in warming estimated by 0.4°C·decade−1 up to 2099. The ERA5 LHF and SHF trends were 4 and 0.6 W·m−2·decade−1, respectively. The MME shows historical (SSP5‐8.5) trends of 0.2 (1.3) W·m−2·decade−1 for LHF and −0.2 (−0.1) W·m−2·decade−1 for SHF. In the Drake Passage, the models accurately reproduced the air–sea mean temperatures; however, they failed to simulate negative trends observed in SAT and SST. Under the high emissions scenario, all CMIP6 models predict an increasing warming trends of 0.1–0.4°C·decade−1 and ocean heat gain of −0.2 to −1.2 (−1 to −2) W·m−2·decade−1 for LHF (SHF). For both regions, spatial analyses of SST and SAT highlight the coupling between the ocean and the atmosphere, alongside changes in air–sea heat fluxes. Our findings reveal inhomogeneous patterns of SST warming trends by the end of the 21st century, which are approximately 2–4 times greater than historical trends. The results suggest the persistence and enhancement of these regions as hotspots with significant potential to influence oceanic and atmospheric dynamics.

Published: June 2024

AbstractBACKGROUNDβ‐Carotene (BC) is difficult to apply effectively in the food industry due to its low solubility and bioavailability. This work aimed to fabricate Moringa oleifera seed protein (MOSP) stabilized emulsions as delivery vehicles for BC and investigate the effect of aqueous phase conditions including pH and ionic strength on this system.RESULTSAll MOSP samples were positively charged and the particle size of MOSP increased with the increase of pH. At pH 5.0 and 0.2 mol L−1 sodium chloride (NaCl), the MOSP emulsion demonstrated the highest stability coefficient and minimal creaming index, while exhibiting a lower release rate in vitro digestion. The rheological behavior of all MOSP emulsions within the frequency range of 0.1–10 Hz was dominated by viscoelasticity, forming an elastic network structure through dispersed droplets. Additionally, the MOSP emulsion loaded with BC prepared at pH 5.0 and 0.2 mol L−1 NaCl displayed enhanced ultraviolet light stability (52.31 ± 0.03% and 51.86 ± 0.05%) as well as thermal stability (72.39 ± 8.67% and 86.78 ± 10.69%). Furthermore, the BC in the emulsion at pH 7.0 exhibited favorable stability (65.14 ± 0.02%) and optimal bioaccessibility (40.30 ± 0.04%) in vitro digestion.CONCLUSIONThe results provided reference data for utilizing MOSP as a novel emulsifier and broadening the application of BC in the food industry. © 2024 Society of Chemical Industry.

AbstractBACKGROUNDGarlic is a promising source of antimicrobial peptide separation, and chemical modification is an effective method for activity improvement. The present study aimed to improve the antifungal activity of a peptide extracted from garlic. Chemical modifications were conducted, and the structure–activity relationship and antifungal mechanism were investigated.RESULTSThe results indicated that the cationic charge induced by Lys residue at the N‐terminal was important for the antimicrobial activity, and the modified sequence exhibited significant antifungal activity with low mammalian toxicity and a low tendency of drug resistance (p < 0.05). The structure–activity relationship analysis revealed that the modified active peptide had a predominant α‐helical structure and an inner cyclic correlation. Transcriptomic analysis showed that peptide KMLKKLFR (Lys‐Met‐Leu‐Lys‐Lyse‐Leu‐Phe‐Arg) affected the rRNA processing and carbon metabolism process of Candida albicans. In addition, the membrane potential study indicated a non‐membrane destruction mechanism, and molecular docking analysis and a DNA interaction assay suggested promising inner targets.CONCLUSIONThe results of the present study indicate that chemical modification by amino acid substitution was effective for antimicrobial activity improvement. The present study would benefit future antimicrobial peptide development and suggests that garlic is a great source of antibacterial peptides and peptide template separations for coping with antibiotic resistance. © 2024 Society of Chemical Industry.

Published: June 2024

AbstractDespite the established association between posttraumatic stress disorder (PTSD) and impulsivity, the literature is limited regarding impulsivity as a multifaceted construct. That is, the field's understanding of how PTSD symptoms may increase particular impulsive tendencies and behaviors is constrained by examining impulsivity solely as an umbrella term. The aim of the present study was to determine if there are differential associations between PTSD symptom severity and various components of impulsivity across multiple self‐report measures. A sample of 215 undergraduate women (M age = 19.77 years, SD = 1.91, Range: 18–39 years) completed the PTSD Checklist for DSM‐5 (PCL‐5), Barratt Impulsiveness Scale (BIS‐11), short version of the UPPS‐P Impulsive Behavior Scale (SUPPS‐P), and Delaying Gratification Inventory (DGI). Structural equation modeling was used to examine associations between PTSD symptoms and each measure's subscales. The findings included significant predictions from PTSD symptoms to the BIS‐11 Attentional Impulsiveness subscale, β = .23, SE = .07, 95% CI [.09, .37]; DGI Physical Pleasures, β = ‐.24, SE = .07, 95% CI [‐.38, ‐.11], and Achievement subscales, β = ‐.19, SE = .08, 95% CI [‐.34, ‐.04]; and the SUPPS‐P Positive Urgency, β = .22, SE = .08, 95% CI [.07, .37], and Negative Urgency subscales, β = .32, SE = .07, 95% CI [.19, .46]. These results have implications for precision medicine approaches that emphasize targeting these specific facets of impulsivity, with likely downstream effects on health risk behaviors for emerging adult women.
Social inequality and body mass differences in two post‐Medieval Dutch populations
Authors: Niu Yuran , Schrader Sarah 
Published: June 2024

AbstractAdult body mass is largely related to nutrition levels, which can be affected by external stressors, such as diet, environment, and disease. High‐status and low‐status groups likely had very different nutrition and stress experiences, which might result in differences in population's body mass. Since inequality between social statuses prevailed in Europe in the post‐Medieval period, did these differences result in body mass variations between high‐status and low‐status populations in the Netherlands? In order to answer this question, this research compared body size of two post‐Medieval urban skeletal collections with different social statuses from the Eusebius cemetery of two cemeteries of the 17th–19th centuries: the Arnhem and the Broerenkerk church of Zwolle, the Netherlands. Social statuses of the two collections are estimated based on the burial locations, grave goods, and historical records. Body mass was estimated using both femoral head diameter method and stature/bi‐iliac breadth method. Results have shown no statistically significant differences in body mass between the two samples. Therefore, this research suggests that inequality in post‐Medieval Dutch society did not result in observable population body mass differences in the skeletal collections of different social status groups. It cannot, however, prove that social inequality in populations did not impact body size or health more broadly.

AbstractObjectiveModerate‐to‐vigorous physical activity (MVPA) improves glucose levels; however, whether its timing affects daily glycemic control remains unclear. This study aims to investigate the impact of lifestyle MVPA timing on daily glycemic control in sedentary adults with overweight/obesity and metabolic impairments.MethodsA total of 186 adults (50% women; age, 46.8 [SD 6.2] years) with overweight/obesity (BMI, 32.9 [SD 3.5] kg/m2) and at least one metabolic impairment participated in this cross‐sectional study. MVPA and glucose patterns were simultaneously monitored over a 14‐day period using a triaxial accelerometer worn on the nondominant wrist and a continuous glucose‐monitoring device, respectively. Each day was classified as “inactive” if no MVPA was accumulated; as “morning,” “afternoon,” or “evening” if >50% of the MVPA minutes for that day were accumulated between 0600 and 1200, 1200 and 1800, or 1800 and 0000 hours, respectively; or as “mixed” if none of the defined time windows accounted for >50% of the MVPA for that day.ResultsAccumulating >50% of total MVPA during the evening was associated with lower 24‐h (mean difference [95% CI], −1.26 mg/dL [95% CI: −2.2 to −0.4]), diurnal (−1.10 mg/dL [95% CI: −2.0 to −0.2]), and nocturnal mean glucose levels (−2.16 mg/dL [95% CI: −3.5 to −0.8]) compared with being inactive. This association was stronger in those participants with impaired glucose regulation. The pattern of these associations was similar in both men and women.ConclusionsThese findings suggest that timing of lifestyle MVPA is significant. Specifically, accumulating more MVPA during the evening appears to have a beneficial effect on glucose homeostasis in sedentary adults with overweight/obesity and metabolic impairments.
Influences of heat treatment on mechanical properties of SCF/PEEK composites in FDM‐3D printing process with UV laser assistance

Published: June 2024

AbstractFused deposition modeling (FDM) process with laser assistance can effectively enhance the interfacial strength of short carbon fiber/poly‐ether‐ether‐ketone (SCF/PEEK) composites. However, excessive crystallization of the semi‐crystalline matrix generally results in irregular shrinkage, which seriously deteriorates dimensional accuracy of composite specimens. To overcome this issue, we establish a novel heat treatment technique by the combinations of laser assistance and post‐treatment to improve the interlayer properties and dimensional accuracy simultaneously. It is found that lateral cracks at the interlayer interfaces can be completely eliminated at laser pre‐heating temperature , due to the reduction of temperature gradient and residual stresses. The further increased evidently promotes molecular diffusion and crystallization behaviors, thus increasing the interlaminar shear strength of FDM‐printed specimens. The post‐treatment temperature visibly promotes mutual diffusions of the molecules and formations of the perfect crystals, strengthening the interlayer adhesion of specimens. The proposed combination technique can increase the interlayer strengths of composite specimens by approximately 22.5%, while their warpage deformations are suppressed simultaneously.Highlights
Pre‐heated temperature was a threshold for eliminating lateral cracks at interlayer interfaces.
Post‐treatment significantly promoted molecular diffusion and crystallization behaviors.
A novel technique was established to improve interlayer strength while suppressing warpage.
The combination technique could increase the interlayer shear strength by approximately 22.5%.
Parameter estimation of inverse Weibull distribution under competing risks based on the expectation–maximization algorithm
Authors: Alotaibi Refah , Rezk Hoda , Park Chanseok 
Published: June 2024

AbstractA system consisting of interconnected components in series is under consideration. This research focuses on estimating the parameters of this system for incomplete lifetime data within the framework of competing risks, employing an underlying inverse Weibull distribution. While one popular method for parameter estimation involves the Newton–Raphson (NR) technique, its sensitivity to initial value selection poses a significant drawback, often resulting in convergence failures. Therefore, this paper opts for the expectation–maximization (EM) algorithm. In competing risks scenarios, the precise cause of failure is frequently unidentified, and these issues can be further complicated by potential censoring. Thus, incompleteness may arise due to both censoring and masking. In this study, we present the EM‐type parameter estimation and demonstrate its superiority over parameter estimation based on the NR method. Two illustrative examples are provided. The proposed method is compared with the existing Weibull competing risks model, revealing the superiority of our approach. Through Monte Carlo simulations, we also examine the sensitivity of the initial value selection for both the NR‐type method and our proposed method.
