Background: This technical note presents a methodological approach to agrichemical inventory documentation. It complements exposure assessments in field settings with time-restricted observational periods. Conducted in Michoacán, Mexico, this method leverages large language model (LLM) capabilities for categorizing agrichemicals from brief video footage. Method: Given time-limited access to a storage shed housing various agrichemicals, a short video was recorded and processed into 31 screenshots. Using OpenAI’s ChatGPT (model: GPT-4o^®), agrichemicals in each image were identified and categorized as fertilizers, herbicides, insecticides, fungicides, or other substances. Results: Human validation revealed that the LLM accurately identified 75% of agrichemicals, with human verification correcting entries. Conclusions: This rapid identification method builds upon behavioral methods of exposure assessment, facilitating initial data collection in contexts where researcher access to hazardous materials may be time limited and would benefit from the efficiency and cross-validation offered by this method. Further refinement of this LLM-assisted approach could optimize accuracy in the identification of agrichemical products and expand its application to complement exposure assessments in field-based research, particularly as LLM technologies rapidly evolve. Most importantly, this Technical Note illustrates how field researchers can strategically harness LLMs under real-world time constraints, opening new possibilities for rapid observational approaches to exposure assessment.

Background: Dental phobia significantly impairs treatment adherence and oral health–related quality of life. While intravenous sedation (IVS) is commonly used to manage anxiety, interest in non-pharmacological alternatives is increasing. Visual color stimuli are known to affect emotional processing and autonomic nervous system activity. This study investigated whether brief exposure to colored goggles (translucent, green, blue, red) influenced physiological and psychological stress markers in patients with dental phobia undergoing IVS. Methods: Twenty patients with dental phobia (CMDAS ≥ 20) participated in a within-subject repeated measures design, experiencing all four color conditions in randomized order via Latin square. Salivary alpha-amylase (sAA), heart rate (HR), and Visual Analog Scale (VAS) scores for pain and satisfaction were measured at four time points. The Friedman test, followed by Wilcoxon signed-rank tests with Bonferroni correction, was used to compare conditions. Results: Prior to peripheral intravenous cannulation (PIC), green goggle exposure significantly reduced median sAA levels compared to the translucent control (p = 0.009). HR was lower in the green and blue conditions than in the red, although not significantly. VAS pain scores were significantly reduced under green and blue conditions; satisfaction scores remained uniformly high across all conditions. Red did not worsen stress responses compared to the control and may promote increased engagement. Conclusions: Cool color stimuli—particularly green and blue—may attenuate acute stress responses in patients with dental phobia prior to PIC. Incorporating such visual cues into preoperative environments may serve as a simple, non-invasive adjunct to managing dental anxiety. Full article

The Ti-6242 titanium alloy samples were forged at 1020 °C (slightly above the β-transus) and subjected to ultra-short isothermal holding (0–320 s) prior to quenching to investigate the rapid microstructural evolution in the parent β phase. Electron backscatter diffraction (EBSD) with parent β-phase reconstruction reveals that within only 1–3 s of holding, a pronounced <111> fiber texture develops along the forging axis, superseding the original <100> deformation fiber. This ultrafast texture change is attributed to metadynamic recrystallization (MDRX)—the post-deformation growth of nuclei formed during dynamic deformation. The newly formed <111>-oriented β grains still contain residual substructure, indicating incomplete strain release consistent with MDRX. Longer holds (tens of seconds) lead to more extensive static recrystallization and normal grain growth, which dilute the strong <111> fiber as grains of other orientations form and coarsen. These findings demonstrate that even a brief pause after forging can markedly alter the prior β texture via a MDRX mechanism. This insight highlights a novel approach to microtexture control in Ti-6242: by leveraging MDRX during short holds, one can potentially disrupt the formation of aligned α colony microtextured regions (MTRs, or “macrozones”) upon subsequent cooling, thereby mitigating dwell-fatigue susceptibility. The study revises the interpretation of the recrystallization mechanism in short-term holds and provides guidance for optimizing β-phase processing to improve fatigue performance. Full article

Background/Objectives: As global aging accelerates, there is a pressing and empirically substantiated demand for integrated and sustainable strategies, as evidenced by the rising prevalence rates of chronic conditions, social isolation, and digital exclusion among older adults worldwide. These factors underscore the urgent need for multidimensional interventions that simultaneously target physical, psychological, and social well-being. The HOPE-FIT (Hybrid Outreach Program for Exercise and Follow-up Integrated Training) model and the SAGE (Senior Active Guided Exercise) program were designed to address this need through a hybrid framework. These programs foster inclusive aging by explicitly bridging digitally underserved groups and mobility-restricted populations into mainstream health promotion systems through tailored exercise, psychosocial support, and smart-home technologies, thereby functioning as a scalable meta-model across healthcare, community, and policy domains. Methods: HOPE-FIT was developed through a formative, multi-phase process grounded in the RE-AIM framework and a Hybrid Type II effectiveness–implementation design. The program combines professional health coaching, home-based and digital exercise routines, Acceptance and Commitment Performance Training (ACPT)-based psychological strategies, and smart-home monitoring technologies. Empirical data from pilot studies, large-scale surveys (N = 1000), and in-depth user evaluations were incorporated to strengthen validity and contextual adaptation. Culturally tailored content and participatory feedback from older adults further informed ecological validity and program refinement. Implementation Strategy/Framework: The theoretical foundation integrates implementation science with behavioral and digital health. The RE-AIM framework guided reach, fidelity, and maintenance planning, while the Hybrid E–I design enabled the concurrent evaluation of effectiveness outcomes and contextual implementation strategies. Institutional partnerships with community centers, public health organizations, and welfare agencies further facilitated the translation of the model into real-world aging contexts. Dissemination Plan: The multi-pronged dissemination strategy includes international symposia, interdisciplinary academic networks, policy briefs, localized community deployment, and secure, authenticated data sharing for reproducibility. This design facilitates evidence-informed policy, empowers practitioners, and advances digital health equity. Ultimately, HOPE-FIT constitutes a scalable and inclusive model that concretely addresses health disparities and promotes active, dignified aging across systems and disciplines. Full article

Jurors play a critical role in the administration of justice, yet their compulsory exposure to graphic and distressing evidence during criminal trials is often overlooked in discussions of mental health and legal reform. This paper investigates the psychological impact of jury service in trials involving murder, domestic violence, sexual assault, and child abuse, where laypeople are required to view autopsy photographs, listen to emergency calls, and assess disturbing testimonies without any formal training or mandatory psychological support. While vicarious trauma, secondary traumatic stress, and moral injury are recognised in research on law enforcement, social work, and healthcare, there is limited acknowledgement that no professional group consistently receives adequate trauma prevention or recovery support. This gap is particularly concerning for jurors, who are laypeople compelled to participate in the justice process. Drawing on legal case studies, psychiatric research, and international precedent, this paper argues that the justice system imposes an invisible emotional burden on jurors while offering limited, inconsistent, and mostly reactive support. Although applicable to many countries, particular attention is given to Australian jurisdictions, where counselling services are sparse and optional, and where juror confidentiality laws restrict therapeutic disclosures. This research also considers the legal and ethical implications of exposing untrained civilians to traumatic material and explores whether the state could, or should, bear legal liability for post-trial psychological harm. Ultimately, this paper calls for the introduction of clearly defined trauma-informed jury procedures, including pre-trial psychological briefings, structured debriefings, and systemic reform, to acknowledge juror well-being as a necessary component of fair and ethical justice.

Background: Phenylketonuria (PKU) is an inherited metabolic disorder that requires early diagnosis and strict phenylalanine (Phe)-restricted diet to prevent neurocognitive impairment. Various infant feeding models have been used to achieve optimal metabolic control during early life. The aim of this study was to compare two different feeding models for infants with classical PKU in terms of metabolic control, growth parameters, micronutrient status, the process of introducing complementary foods, and with a particular focus on sleep quality. Methods: In this prospective observational study, 26 infants with classical PKU were followed for 12 months. Patients were assigned to one of two feeding groups: Group-1 received breast milk and Phe-free formula in alternating feeds, while Group-2 received Phe-free formula followed by breastfeeding until satiety. Blood Phe, micronutrient levels and anthropometric measurements were recorded. Sleep quality was evaluated using the Brief Infant Sleep Questionnaire-Revised (BISQ-R). A structured set of parental questions was used to evaluate their experiences during the complementary feeding period. Results: No statistically significant differences were observed between the groups in terms of blood Phe levels, anthropometric measurements, serum levels of iron, ferritin, vitamin-B12, vitamin-D, and zinc. Complementary feeding tolerance were similar across the groups. The BISQ-R analysis revealed no significant differences between the groups. Conclusions: Both feeding models were equally effective in maintaining metabolic control, supporting normal growth, complementary feeding processes, and preserving sleep quality during infancy. These findings suggest that either approach can be adopted based on the preference of the caregiver and the practicality of the clinical setting. Full article

Non-Intrusive Load Monitoring (NILM) aims to disaggregate a household’s total aggregated power consumption into appliance-level usage, enabling intelligent energy management without the need for intrusive metering. While deep learning has improved NILM significantly, existing NILM models struggle to capture load patterns across both longer time intervals and subtle timings for appliances involving brief or overlapping usage patterns. In this paper, we propose a novel GRU+BERT hybrid architecture, exploring both unidirectional (GRU+BERT) and bidirectional (Bi-GRU+BERT) variants. Our model combines Gated Recurrent Units (GRUs) to capture sequential temporal dependencies with Bidirectional Encoder Representations from Transformers (BERT), which is a transformer-based model that captures rich contextual information across the sequence. The bidirectional variant (Bi-GRU+BERT) processes input sequences in both forward (past to future) and backward (future to past) directions, enabling the model to learn relationships between power consumption values at different time steps more effectively. The unidirectional variant (GRU+BERT) provides an alternative suited for appliances with structured, sequential multi-phase usage patterns, such as dishwashers. By placing the Bi-GRU or GRU layer before BERT, our models first capture local time-based load patterns and then use BERT’s self-attention to understand the broader contextual relationships. This design addresses key limitations of both standalone recurrent and transformer-based models, offering improved performance on transient and irregular appliance loads. Evaluated on the UK-DALE and REDD datasets, the proposed Bi-GRU+BERT and GRU+BERT models show competitive performance compared to several state-of-the-art NILM models while maintaining a comparable model size and training time, demonstrating their practical applicability for real-time energy disaggregation, including potential edge and cloud deployment scenarios.

The present study investigates the bactericidal and anticancer potential of caprylic acid (CA) against Helicobacter pylori infection, a major global risk factor for gastric cancer. Several chronic inflammatory processes, bacterial virulence factors, and carcinogenic mechanisms—capable of inducing DNA damage in gastric epithelial cells, promoting genomic instability, and contributing to the development of gastritis or peptic ulcer disease in susceptible individuals—remain incompletely understood. CA, a medium-chain fatty acid naturally found in plant and animal sources such as coconut oil and goat’s milk, possesses notable biological properties that may confer gastroprotective effects against gastric cancer induced by H. pylori. Despite advances in medical management, no universally effective strategy currently exists for the treatment or prevention of H. pylori–associated gastric cancer. Conventional therapies, including surgery, radiotherapy, and chemotherapy, often entail long-term complications that may affect patients’ nutritional status. In brief, further elucidation of the mechanisms underlying medium-chain fatty acid metabolism, particularly that of CA in gastric cancer cells, may yield valuable insights for the development of innovative therapeutic approaches. Consequently, the integration of CA into therapeutic dietary regimens and the formulation of nutraceuticals targeting H. pylori infection and related gastric pathologies warrant consideration. Therefore, CA could be considered a potential adjuvant in the preventive treatment of H. pylori–induced gastritis and its associated complications. However, further in vitro and in vivo studies are needed to confirm its beneficial use for this pathology. Full article

Prescriptive grammars of Netherlandic Dutch usually explicitly warn against mixing T- and V-pronouns. Although the prescriptive norm opposes mixing, pronoun mixing does occur, and its use can often be interpreted as strategic, in the sense that mixing pronouns might help to balance conflicting needs such as signaling respect and formality to the addressee on the one hand as well as expressing closeness on the other hand. This article explores the perception of pronoun mixing among high school students who were in the process of acquiring the norm. As part of a student science project, we asked students to categorize real-world examples of pronoun mixing that they themselves had gathered as a strategy or as a mistake. Based on the students’ responses, we extrapolated that the most acceptable forms of mixing were brief switches to V in a T-context to express humor or urgency and—if there was no clear default pronoun—that mixing was most acceptable (1) when the text was free of spelling errors and other signs of sloppiness, (2) when the mixing was intersentential, (3) when the number of switches was infrequent, and (4) when there was a clear division of tasks between the pronouns. As an offshoot of this student science project, we designed a brief follow-up survey to gain insight into domains and consensus and variation among the students’ perceptions of pronoun mixing. This follow-up survey revealed that if not explicitly asked, most students do not notice pronoun mixing. We asked students to rank four real-life examples of address pronoun mixing that they had gathered during the student science project. We expected that with respect to their perception of the mixing of address pronouns all students would rank examples of mixing in the same order. A primary result of this part of our exploration was that there were large individual differences in the perception of mixing and that there was variation in the ranking of examples among the students. Intersentential mixing yielded the most neutral evaluations by the students, but intrasentential mixing showed the most extreme evaluations. It was disliked most strongly by students who had a general dislike of mixing and liked best by students who appreciated mixing as a style. Briefly switching to V in contexts associated with the T-pronoun was perceived to be humorous by a quarter of the students, and half of the students perceived a switch to the petrified abbreviation AUB (‘if you-V please’) as expressing urgency.

After a brief review of the concept of fertility in antiquity—from mythological, historical, religious, and artistic perspectives—this conceptual review examines the evolution of the notion of fertility in fruit growing, considering both its biological and agronomic dimensions. The discussion addresses the phenomena underlying the production process and the quantitative and qualitative yields of fruit trees, including the interactions between vegetative growth and reproductive aspects, as well as various interferences—such as alternate bearing or sterility—that mediate between potential and actual fertility. These aspects are analyzed in light of both well-established studies and the most recent research findings. Furthermore, a holistic and comprehensive approach is presented, aiming to transcend the limitations of a purely biological interpretation and to clarify certain ambiguities in the use of the term “fertility,” with particular focus on the physiology of flowering and fruiting in a paradigmatic Mediterranean fruit tree species (Olea europaea L. subsp. europaea var. europaea). Finally, the potential contributions of recent advances in the understanding of flowering and fruiting biology are discussed, particularly in relation to genetic improvement and the development of simulation models for the bio-agronomic behavior of fruit trees. Future perspectives are also explored, especially regarding bio-agronomic strategies to address alternate bearing. Full article

This article presents a collection of schlieren visualizations captured using a custom-built, laboratory-based imaging system, designed to explore a wide range of flow and refractive phenomena. The experiments were conducted as a series of observational case studies, serving as educational bloc notes for students and researchers working in fluid mechanics, optics, and high-speed imaging. High-resolution images illustrate various phenomena including shockwave propagation from bursting balloons, vapor plume formation from volatile liquids, optical surface imperfections in transparent materials, and the dynamic collapse of soap bubbles. Each image is accompanied by brief experimental context and interpretation, highlighting the physical principles revealed through the schlieren technique. The resulting collection emphasizes the accessibility of flow visualization in a teaching laboratory, and its value in making invisible physical processes intuitively understandable. Full article

Background: This paper empirically tests the new multi-level Associationalist Demand Control (ADC) theory by applying the Job Content Questionnaire (JCQ) 2.0 that assesses both a wide range of task characteristics as well as work organizational and external-to-work psychosocial characteristics. Methods: The paper is based on four JCQ 2.0 pilot studies among 16,125 workers in Korea, China, Australia, and Germany. All pilots used the original JCQ task-level scales and then added newly developed proposed items and scales, evolving more comprehensive higher-level scales from pilot to pilot from 2005 to 2011. A brief review of the analytic process is presented, followed by an assessment of the internal consistency and concurrent validity of the final 25 multi-level JCQ 2.0 scales at the task, the organizational, and the external levels. Results: Adequate psychometric properties were established for the JCQ 2.0 pilot scales. The extended set of task-level scales was found to be robust across all samples; the new organizational scales mainly showed adequate internal consistency with α > 0.7 in Australia and Germany (tested only there) and were associated with relevant work- and health-related outcome measures as expected. Similarly, the external-to-work scales (tested only in Germany) had adequate Cronbach’s Alpha values and showed expected associations to relevant outcome scales. Conclusions: Although not all scales were available in all countries, overall, the results support the “functional similarity” of the major scale areas across the four pilot countries and support the underlying extensions of the Demand–Control theoretical constructs to the multi-level psychosocial work assessment for the promotion of workers’ health and wellbeing as suggested by the new ADC model.

Polymer structuring is a valuable cost- and time-saving strategy for the production of high-performance polymer-based materials. The main issue in the spreading of this approach lies in the understanding of the relationships between the processing parameters, the microstructure and the resulting properties, which represent fundamental factors in the actual defining of the final characteristics owing to the production method employed. The aim of the present work is to provide a wide overview of the currently available knowledge on solvent-free approaches for obtaining structured materials, specifically focusing on extrusion- and injection molding-based technologies, given their relevance as the most industrially exploited methods for the melt processing of thermoplastic materials. Additionally, particular attention will be paid to the relationships between the variation in the processing parameters and the resulting flow fields (both shear and elongational), considering their role in the definition of microstructure.

Safety behaviors are mental processes and behaviors associated with the onset, maintenance, and treatment of anxiety-related disorders. But these behaviors are understudied in the context of posttraumatic stress disorder (PTSD). One reason is the lack of psychometrically valid instruments to assess safety behaviors specific to the diagnosis of PTSD. To address this gap in the literature, we adapted a well-validated general measure of safety behaviors to create a brief 10-item questionnaire for assessing PTSD-specific safety behaviors—the Safety Behavior Assessment Form-PTSD scale (SBAF-PTSD scale). The results of four studies, using both clinical and non-clinical populations, supported the reliability and validity of the SBAF-PTSD scale; the measure demonstrated strong internal consistency, test–retest reliability, inter-item correlations, and convergent and divergent validity across all four studies. It also demonstrated clinical utility as it predicted treatment outcomes for American military veterans diagnosed with PTSD. Results provide initial support for this measure as a tool that can be used in both research and in clinical practice (e.g., treatment monitoring). Full article
