Authors: Xu Xiaosu , Su Yujie , Zhang Huanhuan , Zhang Yunfeng , Hao Shanshan 
Published: June 2024

Abstract

This study investigates the burgeoning interest in ChatGPT's role in education, with a particular emphasis on its effects on postgraduate students' English-speaking proficiency, a topic previously explored mainly through theoretical lenses with scant empirical evidence. The research aims to fill this gap by examining the experiences and perceptions of Chinese postgraduate students using ChatGPT for IELTS speaking practice. Employing a mixed-methods approach, the study combines experimental engagement with ChatGPT, analysis of reflective diaries, and responses from questionnaires to gauge the platform's efficacy in fostering enthusiasm for English language practice. The findings indicate a positive impact of ChatGPT on learners' engagement, as evidenced by an increase in practice frequency. A significant correlation was observed between regular interaction with ChatGPT and improvements in English grammar skills among participants. Thematic analysis of reflective diaries highlighted ChatGPT's contribution to language learning and students' proactive approach to acquiring English-speaking skills. Nonetheless, there was a consensus among students for a need for more human-like interactions from ChatGPT. The study contributes valuable insights into the potential of chatbots to enhance English-speaking skills in EFL contexts, offering practical recommendations for educators and developers to optimize chatbot learning experiences.

Abstract

T-cell receptor stimulation (TCR) by antigen bound to the major histocompatibility complex (MHC) on an antigen-presenting cell (APC) induces protein kinase C (PKC) activation and the formation of the immune synapse (IS), followed by depletion of filamentous actin (F-actin) at the central region of the IS (cIS) and the polarization of multivesicular bodies (MVB) and the microtubule-organizing center (MTOC) to the IS. These events lead to polarized exosome secretion at the IS. These exosomes are involved in several crucial immune responses such as autocrine activation-induced cell death (AICD) of T lymphocytes and cytotoxicity. We analysed here how formin-like 1 beta (FMNL1beta), an actin cytoskeleton-regulatory protein, regulates MTOC/MVB polarization and exosome secretion at an IS model in a phosphorylation-dependent manner. IS formation was associated with transient recruitment of FMNL1beta to the IS, which was independent of protein kinase C delta (PKCdelta). Simultaneous RNA interference of all FMNL1 isoforms prevented MTOC/MVB polarization and exosome secretion, which were restored by FMNL1betaWT expression. However, expression of the non-phosphorylatable mutant FMNL1βS1086A did not restore neither MTOC/MVB polarization nor exosome secretion to control levels, supporting the crucial role of S1086 phosphorylation in MTOC/MVB polarization and exosome secretion. In contrast, the phosphomimetic mutant, FMNL1βS1086D, restored MTOC/MVB polarization and exosome secretion. Conversely, FMNL1βS1086D mutant did not recover the deficient MTOC/MVB polarization occurring in PKCdelta-interfered clones, indicating that S1086 FMNL1beta phosphorylation alone is not sufficient for MTOC/MVB polarization and exosome secretion. FMNL1 interference inhibited the depletion of F-actin at the cIS, which is necessary for MTOC/MVB polarization. FMNL1betaWT and FMNL1βS1086D, but not FMNL1βS1086A expression, restored F-actin depletion at the cIS. Thus, actin cytoskeleton reorganization at the IS underlies the effects of all these FMNL1beta variants on polarized secretory traffic. FMNL1 was found in the IS made by primary T lymphocytes, both in TCR and chimeric antigen receptor (CAR)-evoked synapses. Taken together, these results point out a crucial role of S1086 phosphorylation in FMNL1beta activation, leading to cortical actin reorganization and subsequent control of MTOC/MVB polarization and exosome secretion.

Abstract

Water treatment residual (WTR) is a burden for many water treatment plants due to the large volumes and associated management costs. Here, we transform aluminum-salt WTR (Al-WTR) into ceramsite (ASC) to recover phosphate from challenging waters. ASC showed remarkably higher specific surface area (SSA, 70.53 m2/g) and phosphate adsorption capacity (calculated 47.2 mg P/g) compared with previously reported ceramsite materials (< 40 m2/g SSA and < 20 mg P/g). ASC recovered > 94.9% phosphate over a wide pH range (3 – 11) and generally sustained > 90% of its phosphate recovery at high concentrations of competing anions (i.e., Cl-, F-, SO42-, or HCO3-) or humic acid (HA). We challenged the material with real municipal wastewater at 10℃ and achieved simultaneous phosphate (>97.1%) and COD removal (71.2%). Once saturated with phosphate, ASC can be repurposed for landscaping or soil amendment. Economic analysis indicates that ASC can be a competitive alternative to natural clay-based ceramsite, biochar, or other useful materials. Therefore, ASC is an eco-friendly, cost-effective adsorbent for phosphate recovery from complex waters, shedding light upon a circular economy in the water sector.
Synopsis: Ceramsite made from aluminum-salt water treatment residual exhibited great capability of recovering phosphate from waters under challenging conditions.

Published: June 2024

Abstract

Endometriosis affects 1 in 9 women. Current medical and surgical management strategies are not always effective and often result in significant side effects, including sub-optimal pain management. Exercise may exhibit benefits to those with endometriosis, via hormonal and/or inflammatory cytokine mediation pathways. However, previous research has provided mixed results about the impact of exercise, with some studies reporting significant adverse effects. This study aims to determine if those with endometriosis are engaging in exercise, what type(s) of exercise and what impact it has on their symptoms. A cross-sectional online survey was conducted via Qualtrics (August to October 2022). Inclusion criteria included endometriosis diagnosis, 18 + years of age and living in Australia or Aotearoa New Zealand (NZ). 424 responses were received, 63% from Australia and 37% from NZ. 73.8% exercised regularly (weekly basis), with walking the most common modality (87.8%). More than half of respondents revealed exercise was part of their endometriosis self-management strategy (51.6%). The majority of respondents exercised for mental health benefits (84.5%). Negative effects on endometriosis symptoms (e.g. pain) was the most frequently reported reason for not currently exercising (36.6%). This study showed many people with endometriosis in Australia and NZ chose to exercise regularly. Some respondents reported not currently exercising due to negative effects on symptoms, but many used exercise for symptom management, or to benefit their ongoing physical and mental health. Exercise may be a promising avenue for non-surgical treatment of endometriosis, but further research is needed to explore appropriate exercise prescription to limit symptom exacerbation.
Generation principle for the robust comb-like resonant modes in photonic crystal ring resonator
Authors: Ge Rui , Xing Dengke 
Published: June 2024

Abstract

Topological valley photonic crystal cavity supports the robust comb-like resonant modes, and thus is widely applied in chiral coupling of quantum dots, laser, nonlinear frequency conversion process, and photonic logical elements. So far, its robustness is mostly attributed to the different topological properties of the valley photonic crystals. In this work, we illustrate that the position of circular polarization topological singularity is the most important factor to generate comb-like resonant modes with robustness. We proposed a photonic crystal ring resonator purely by the linedefect waveguide, and simulation results demonstrate that the proposed cavity can generate robust comb-like resonant modes. This work can provide guidance to the design of high-quality and robust photonic crystal cavity.

Abstract

Background: Coronary heart disease (CHD) is a serious condition with significant impacts on morbidity, mortality and healthcare costs, particularly prevalent among police officers. Police are a high-risk occupational group due to their activities. Police work is thought to be associated with high workload, occupational stress, disordered eating, lack of exercise, limited food options at work, overtime and shift work, as well as sleep disturbances which are significantly correlated with the risk of CHD. This research aims to investigate the variances in coronary heart disease (CHD) incidence and risk factors among urban and rural police officers within the East Java Regional Police, providing an assessment and strategic preventive approach for CHD.
Results: A cross-sectional study enrolled 766 participants, comprising 383 urban police officers and 383 rural police officers. Data were collected during medical check-ups at the Bhayangkara State Police Hospital Surabaya in 2024, including complete physical and laboratory examinations such as initial electrocardiography, treadmill tests, total cholesterol and fasting blood sugar. CHD was assessed by ischaemic changes in ECG and/or symptoms during treadmill testing, pre-existing evidence from medical history e.g. previous cardiac events (MI, angina) angiography. The Mann-Whitney U test was performed using IBM SPSS version 26. CHD prevalence was significantly higher in urban police officers (89.7%) compared to rural police officers (10.3%) (p=0.000). Total cholesterol, as a risk factor variable, showed a significant correlation with CHD (p=0.003, p<0.05).
Conclusions: Both urban and rural police officers exhibit CHD risk, with urban officers demonstrating a higher prevalence. These findings underscore the importance of implementing aggressive CHD prevention strategies, treatments, early clinical and echocardiographic follow-ups to improve outcomes.

Published: June 2024

Abstract

We present novel mathematical models for inventory management within a reverse logistics system. Technological advancements, sustainability initiatives, and evolving customer behaviours have significantly increased the demand for repaired products. Our models account for varying demand levels for newly produced and repaired items. To optimize overall costs with constrained scenarios, we formulated mixed integer programming problems. Solution procedures for the proposed problems are introduced, and the accuracy of these solutions has been validated through numerical experiments. Additionally, we address the cost of waste disposal as an environmental concern. This paper develops a multiobjective mathematical model and provides an algorithm for the Pareto solution. Various scalarization techniques are utilized to identify the Pareto front, and a comparison of these techniques is presented.

Abstract

Background
Internet-based cognitive behavioral therapy (iCBT) shows promise in the prevention of depression. However, the specific iCBT components that contribute to its effectiveness remain unclear.

Objective
We aim to evaluate the effects of iCBT components in preventing depression among university students.

Methods
Using a smartphone cognitive behavioral therapy (CBT) app, we randomly allocated university students to the presence or absence of 5 different iCBT components: self-monitoring, behavioral activation, cognitive restructuring, assertiveness training, and problem-solving. The active intervention lasted 8 weeks but the app remained accessible through the follow-up. The primary outcome was the onset of a major depressive episode (MDE) between baseline and the follow-up after 52 weeks, as assessed with the computerized World Health Organization Composite International Diagnostic Interview. Secondary outcomes included changes in the 9-item Patient Health Questionnaire, 7-item General Anxiety Disorder, and CBT Skills Scale.

Results
During the 12-month follow-up, 133 of 1301 (10) participants reported the onset of an MDE. There were no significant differences in the incidence of MDEs between the groups with or without each component (hazard ratios ranged from 0.85, 95% CI 0.60‐1.20, for assertiveness training to 1.26, 95% CI 0.88‐1.79, for self-monitoring). Furthermore, there were no significant differences in the changes on the 9-item Patient Health Questionnaire, 7-item General Anxiety Disorder, or for CBT Skills Scale between component allocation groups. However, significant reductions in depression and anxiety symptoms were observed among all participants at the 52-week follow-up.

Conclusions
In this study, we could not identify any specific iCBT components that were effective in preventing depression or the acquisition of CBT skills over the 12-month follow-up period, but all participants with and without intervention of each iCBT component demonstrated significant improvements in depressive and anxiety symptoms. Further research is needed to explore the potential impact of frequency of psychological assessments, nonspecific intervention effects, natural change in the mental state, and the baseline depression level.
