subject: antimicrobial activity; apoptosis; glioma cancer; mitochondrial membrane potential; NiO; NiO-PF 127-FA
description: Drug-resistant bacteria and cancer remain major challenges in healthcare, highlighting the need for multifunctional nanomaterials. In this study, folic acid- and Pluronic F127-modified nickel oxide nanocomposites (NiOPF127FA) were synthesized via a one-pot method, and their invitro antibacterial, antioxidant, and anticancer properties were evaluated. XRD analysis showed a crystallite size of 19.42 nm for NiOPF127FA, while PL spectra exhibited a green emission peak at 507 nm, indicative of structural defects in the NiO lattice. NiOPF127FA displayed enhanced antibacterial activity against MRSA and Candida albicans compared to bare NiO, as evidenced by larger inhibition zones and lower MIC and MBC values. The DPPH assay demonstrated improved radical scavenging activity of the modified nanocomposites, likely related to their smaller size, higher surface area, and surface defect-mediated electron transfer. Invitro anticancer studies using rat C6 glioblastoma cells revealed dose-dependent decreases in cell viability, with IC50 values of 12.3 ?g/mL for NiO and 9.6 ?g/mL for NiOPF127FA. Fluorescence staining with AO/EB and DAPI indicated morphological changes in nuclei and alterations in MMP, consistent with induction of cell death. Overall, these findings suggest that NiOPF127FA nanocomposites exhibit improved invitro biological activity, providing a foundation for further preclinical investigations of their potential biomedical applications. 2026 John Wiley & Sons Ltd.

A Pathway to Better EMI Shielding Performance in Natural Rubber Through Ternary Carbonaceous Filler Systems
subject: dielectric; EMI shielding; hybrid fillers; natural rubber; viscoelatic
description: In the present study, we fabricated and characterized ternary hybrid fillers of conductive carbon black (CCB), carbon nanotubes (CNT), and reduced graphene oxide (RGO) reinforced natural rubber (NR) composites. The ternary filler system exhibited good filler-polymer interaction as observed from the cure characteristics and mechanical properties. We used impedance analysis to study the dielectric permittivity and associated polarization mechanisms, and the AC conductivity was fitted using the Jonsher Power law. The presence of functional groups on the ternary nanofiller surfaces caused increased filler-filler interactions, leading to the formation of an excellent conductive network. Mechanical and viscoelastic studies revealed the reinforcing effect of the CCB, CNT, and RGO fillers. The theoretical models, such as Nicolais-Narkis and Turcsanyi, were employed to predict the tensile strength. Morphological analysis confirms the homogeneous dispersion of filler in the matrix. The present system also demonstrated excellent electromagnetic interference (EMI) shielding performance, with the highest shielding effectiveness (SE) values of 37.4 and 35.3 dB at 12 GHz for the ternary composites, satisfying commercial requirements. 2026 John Wiley & Sons Ltd.

Biogenic Carboxymethyl Cellulose and L-Histidine Coated Barium Peroxide Nanocomposite: A Tri-Functional Platform Targeting Antimicrobial Resistance, Cancer, and Oxidative Stress
subject: barium peroxide; Candida albicans; carboxymethyl cellulose; DPPH free radical scavenging assay; L-histidine; MRSA; osteosarcoma MG-63
description: The study addresses the urgent need for novel therapeutic agents in combating multidrug-resistant pathogens, cancer, and oxidative stress-related diseases. Barium peroxide (BaO2) nanoparticles and its novel nanocomposite, carboxymethyl cellulose and L-histidine coated BaO2 (BaO2-CMC-LH) were synthesized, characterized, and evaluated for their antibacterial, anticancer, and DPPH radical scavenging activities. Structural and functional characterizations were carried out using various analytical techniques. Biological evaluations demonstrated enhanced antibacterial activity against Methicillin-resistant Staphylococcus aureus (MRSA) and Candida albicans (C. albicans), with BaO2-CMC-LH exhibiting superior inhibition zones compared to BaO2. For MRSA, the zone of inhibition (ZOI) for BaO2 is about 9 mm, whereas the BaO2-CMC-LH nanocomposite exhibits a substantially larger ZOI of 21 mm. Likewise, for C. albicans, BaO2 presents a ZOI of 12 mm, and BaO2-CMC-LH exhibits a greater inhibition zone of 18 mm. Cytotoxicity analysis against osteosarcoma MG-63 cells revealed significantly improved anticancer activity, with BaO2-CMC-LH achieving an IC?? value of 28.6 ?g/mL compared to 53.3 ?g/mL for BaO2. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay showed that the BaO2-CMC-LH nanocomposite (78.45%) had activity compared to BaO2 alone (64.43%). These findings underscore the synergistic effects of the CMC-LH matrix in enhancing BaO2's biological activities, positioning BaO2-CMC-LH as a promising multifunctional therapeutic agent for addressing global health challenges. 2026 John Wiley & Sons Ltd.

Pluronic F127 and Dopamine Functionalized Fe2O3 Nanocomposites: A Multifunctional Polymer-Based Platform for Anticancer, Antibacterial, and Antioxidant Applications
subject: antibacterial activity; anticancer activity; antioxidant activity; biomedical applications; Fe2O3-PF127-DOP nanocomposites; HCT-116 colon cancer cells; reactive oxygen species
description: Cancer, bacterial infections, and oxidative stress continue to pose serious global health challenges, necessitating the development of multifunctional therapeutic agents. Iron oxide (Fe2O3) nanoparticles were selected as the core material owing to their intrinsic biocompatibility, redox activity, and established biomedical relevance. To overcome the limitations of particle aggregation and poor solubility, pluronic F127 (a biocompatible triblock copolymer) was employed as a stabilizer, while dopamine was introduced as a surface modifier to enhance functionalization, improve dispersion, and facilitate cellular uptake. The resulting Fe2O3-PF127-DOP nanocomposites were thoroughly characterized using XRD, FTIR, SEM, TEM, PL, and XPS analyses, confirming successful functionalization and enhanced stability. Antioxidant assays revealed 79.24% activity at 20 ?g/mL, comparable to Vitamin C, highlighting its antioxidant activity. Antibacterial studies against multiple pathogenic strains, including Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Shigella dysenteriae, and Vibrio cholerae, showed markedly larger inhibition zones for Fe2O3-PF127-DOP than for Fe2O3, confirming its broad-spectrum antibacterial potential. Fe2O3-PF127-DOP exhibited superior cytotoxicity against HCT-116 colon cancer cells (IC50 = 15.3 ?g/mL) compared to Fe2O3 (IC50 = 17.2 ?g/mL), attributed to improved uptake and ROS-mediated apoptosis. Importantly, cytocompatibility studies on L929 fibroblast cells revealed high cell viability of 83% and 86% for Fe2O3 and Fe2O3-PF127-DOP, respectively, demonstrating the nanocomposite's biocompatibility. Overall, this study demonstrates that strategic functionalization of Fe2O3 with pluronic F127 and dopamine yields a stable, multifunctional nanocomposite with significant anticancer, antioxidant, and antibacterial applications. 2025 John Wiley & Sons Ltd.

Biocompatible Sodium Alginate Modified BaO2H2O2 Nanoparticles With Improved Therapeutic Efficacy Against Multidrug-Resistant Pathogens and Cancer Cells
subject: antibacterial; anticancer; antifungal; barium peroxide; SA; surface modification
description: The increasing problem of multidrug-resistant pathogens and the limitations of conventional therapies for cancer treatments require designing new therapeutic agents. BaO2H2O2 and BaSA nanoparticles were prepared and characterized to determine their antimicrobial, antifungal, and anticancer activities. The XRD confirmed the crystallite sizes to be 34 nm for BaO2H2O2 and 25 nm for BaSA. The UVvisible analysis confirmed the band gap energies as 4.13 and 4.11 eV for BaO2H2O2 and BaSA, respectively. A shift in the blue-green PL emission from 488510 nm in BaO2H2O2 to 535 nm in BaSA indicated increased oxygen vacancies. EDAX analysis demonstrated elemental variations due to SA modification, whereas DLS measurements showed a decrease in the mean size of the nanoparticles from 116.70 nm (BaO2H2O2) to 111.90 nm (BaSA). Antimicrobial activity was shown against Klebsiella pneumoniae, Shigella dysenteriae, Escherichia coli, Pseudomonas aeruginosa, and Proteus vulgaris, while a considerable enhancement of antifungal activity against Candida albicans was observed in BaSA. Against MG-63 osteosarcoma cells, BaSA exhibited lower IC50 values (21.5, 20.2, 18.7 ?g mL?1 at 24, 48, and 72 h) when compared with BaO2H2O2 (23.4, 22.5, 21.3 ?g mL?1). Zebrafish embryos tolerated BaSA at 0.5 mg mL?1, with developmental abnormalities observed only at 1.0 mg mL?1. 2025 John Wiley & Sons Ltd.

Influence of Material Composition and Printing Parameters on Impact Strength and Hardness Properties of SLA-Fabricated BN/Resin Composites
subject: additive manufacturing; BN/resin composites; hardness; impact strength; statistical analysis; stereolithography (SLA)
description: The impact strength and hardness characteristics of boron nitride (BN) reinforced photosensitive resin composites made by stereolithography (SLA) 3D printing are examined in this work in relation to the effects of material composition and printing settings. Taking into account the process factors of material composition, lift speed, build angle, and post-curing time, a Taguchi L16 orthogonal array was utilized to optimize the design parameters. Analysis of variance (ANOVA) and the signal-to-noise (S/N) ratio were used to examine the experimental data. Material composition of 1 wt% BN, build angle of 0, post-curing time of 60 min, and lift speed of 30 mm/min were the ideal process parameters for high impact strength, according to the S/N ratio analysis. For high hardness, the ideal parameters were the material composition of 1 wt% BN, a build angle of 90, a post-curing time of 90 min, and a lift speed of 45 mm/min. According to ANOVA results, the build angle had the biggest impact on hardness (56.74%), whereas post-curing time had the biggest impact on impact strength (49.66%). The study also indicates that all parameters should be tuned simultaneously for their combined influence on the mechanical characteristics, according to interaction graphs. 2025 John Wiley & Sons Ltd.

Optimized Multi-Scale Attention Convolutional Neural Network for Micro-Grid Energy Management System Employing in Internet of Things
subject: convolutional neural network; ensemble Kalman filter; fault detection; internet of things; microgrid energy management; sheep flock optimization
description: The combination of micro-grid energy management systems (EMSs) with the Internet of Things (IoT) offers a promising way to improve energy use and distribution. However, challenges such as device compatibility and the difficulty of managing energy efficiently make it hard to implement these systems effectively. This study offers a significant advancement in energy management by using IoT for microgrid systems. An Optimized Multi-scale Attention Convolutional Neural Network for microgrid EMS employing IoT (OMACNN-MGEMS-IoT) is proposed in this study, which enables efficient monitoring and control of energy resources. The proposed model's input data are gathered from the MQTT dataset. This research employs a Regularized Bias-aware Ensemble Kalman Filter (RBAEKF) for pre-processing input data, ensuring the removal of outliers and updating missing values. The MACNN is then used for effective fault detection within the microgrid. To enhance its performance, the Sheep Flock Optimization Algorithm (SFOA) is introduced to optimize the MACNN parameters, ensuring accurate fault detection. Implemented on the MATLAB platform, the performance of the OMACNN-MGEMS-IoT method is assessed through various performance metrics, demonstrating significant improvements. Notably, the proposed method achieves higher cost reductions of 25%, 22%, and 26% compared to existing approaches such as the IoT platform for energy management in multi-micro grid systems (IoT-PEM-MMS), a micro-grid system infrastructure implementing IoT for efficient energy management in buildings (MSII-IoT-EEM) and a hybrid deep learning-based online energy management scheme for industrial microgrids (HDL-OEM-IM). The findings highlight the impact of the proposed OMACNN-MGEMS-IoT method in enhancing energy efficiency and cost-effectiveness in microgrid systems. 2025 John Wiley & Sons Ltd.

A Three-Species Model With Predator-Taxis Sensitivity: Hopf Bifurcation and Active Control Stabilization
subject: active control method; fear effect; fractional Hopf bifurcation; predator-taxis sensitivity; stability analysis
description: This study presents an analysis of a novel fractional two preyone predator model incorporating predator-taxis sensitivity. We conduct a comprehensive stability analysis, explore the model's chaotic nature through period-doubling bifurcations, and also show the existence of limit cycles through fractional Hopf bifurcation. It is observed that the fractional-order parameter brings in a stabilizing effect and, simultaneously, a shift of the Hopf bifurcation point. At the Hopf bifurcation point, the system moves from stable equilibria to sustained oscillations. In addition, regardless of initial conditions, the system approaches a stable limit cycle, showing the robustness of the method. We also demonstrate the effectiveness of the active control method to eliminate the periodicity of the fractional system and also unravel the decelerating influence of the fractional-order parameter on the convergence time to equilibrium. These results provide valuable insights into the stabilization of ecosystem dynamics and contribute more broadly to our understanding of population dynamics in ecological systems. 2025 John Wiley & Sons Ltd.

Deterministic, Stochastic, and Deep Learning Approaches to Understand the Economic Fluctuations in India
subject: GDP; inflation; long short-term memory; stochastic model; unemployment
description: In the present work, a new mathematical framework is proposed for studying the interrelation among population growth rate, GDP, inflation rate, and unemployment rate within deterministic and stochastic frameworks. The values of the parameters of the proposed model are estimated using real data from India. The local and global uniqueness of solutions is established for the stochastic model. The deterministic model is solved by using the Adams-Bashforth-Moulton predictor-corrector method, and Milstein's method is used for solving the stochastic model. Numerical simulations correlated quite strongly with observed data, while projections for the 20242030 period indicate that controlled population growth bodes well for the outlook of the economy for India, supporting economic prosperity alongside reduced inflation and better employment conditions. The findings presented in this work are correlational; therefore, to find the possible cause for this phenomenon, further research is required with detailed datasets. Comparing our model's GDP predictions with that obtained using a long short-term memory recurrent neural network model returned very high values of predictive accuracy, thus reinforcing the strength and reliability of our framework. 2025 John Wiley & Sons Ltd.

Exploring Revenge Travel Intentions to Offbeat Destinations: Assessing the Mediating and Moderating Mechanisms
subject: health belief model; mental health; offbeat destinations; revenge travel; theory of planned behavior; travel behavior
description: This study integrates the Health Belief Model and Theory of Planned Behavior to examine factors influencing revenge travel intentions to offbeat destinations, including perceived susceptibility, perceived severity, perceived benefits, perceived barriers, attitude, social norms, and perceived behavioral control. It also explores the moderating role of social media influencer information search. Data from 363 online survey responses were analyzed using SmartPLS and structural equation modeling. Results show that constructs from both models significantly impact revenge travel intentions to offbeat destinations, with attitude and perceived behavioral control as partial mediators. Notably, social media information search strengthens the positive link between attitudes toward offbeat tourism and revenge travel intentions to offbeat destinations. The proposed model outperforms the original models in predictive capacity. The study acknowledges its limitations and discusses theoretical and practical implications for understanding revenge travel behavior to offbeat destinations. 2026 The Author(s).

Personal Cognitive Predictors Influencing Career Resilience Among Indian Women Information Technology Professionals
subject: career resilience; career salience; career self-management; Indian information technology industry; occupational self-efficacy; women professionals; work volition
description: Career resilience, which is culturally and contextually determined, has been insufficiently explored in the literature regarding women, with an inadequate investigation into the factors predicting their resilience. This investigation offers fresh insights into the determinants of career resilience among women professionals in the Indian information technology sector by examining career-related personal cognitive factors. The study specifically explored the effects of career self-management skills, work volition, career salience, and occupational self-efficacy on career resilience (N = 306). Hierarchical multiple regression analysis revealed that career self-management skills, work volition, and occupational self-efficacy significantly predicted career resilience in women professionals. Additional analyses revealed occupational self-efficacy as a mediating factor. These findings contribute to formulating strategies to enhance career resilience through organizational support and targeted interventions. 2025 by the American Counseling Association.

Transition in Kpen Climate Zones and Its Impacts on Hydroclimatic Extremes Across India
subject: climate change; climate zones; drought; hydroclimatic extremes; SPEI; SPI
description: Shifting climatic zones across India are reshaping the country's hydroclimatic balance, with significant consequences for drought behaviour and water security. This study examines how spatial changes in KpenGeiger climate zones between two climatological periods (19611990 and 19912020) are influencing long-term drought characteristics. Using high-resolution gridded rainfall and temperature data from the India Meteorological Department, the Standardised Precipitation Index (SPI) and the Standardised Precipitation Evapotranspiration Index (SPEI) are used to assess drought intensity and extent across five major climate categories: tropical, arid, temperate, continental and polar. Results reveal a noticeable expansion of the arid zone by 3.86% and a contraction of the temperate zone by 6.94%, indicating a transition toward warmer and drier climates. These spatial shifts have altered regional drought behaviour, with formerly moderate zones experiencing more frequent and intense droughts. The arid and tropical zones, where expansion is observed, show increasing drought severity, largely driven by rising evapotranspiration due to temperature increases of 0.12C0.25C/decade (Tmax) and 0.10C0.20C/decade (Tmin). In contrast, regions where the temperate climate is receding are showing a loss of climatic buffering capacity against drought. SPEI captures more widespread and severe drought events than SPI, underscoring the increasing role of thermal stress in water balance anomalies. This study highlights that changes in the spatial extent of climate zones are a key driver of evolving drought patterns in India. Recognising these shifts is essential for improving temperature-sensitive drought monitoring and formulating zone-specific adaptation strategies in the face of accelerating climate change. 2026 Royal Meteorological Society.

Executive Function Decline and Its Association With TNF-? in the Later Stages of Post-Acute Sequelae of COVID
subject: brain fog; cognitive decline; executive functions; inflammation; post-COVID syndrome
description: Beyond the immediate impact of the COVID-19 pandemic, survivors often grapple with incapacitating post-infection symptoms, referred to as Post-Acute Sequelae of COVID (PASC) when persistent beyond 90 days. Cognitive manifestations, encompassing attention, memory, and executive functions (EF), collectively termed brain fog, contribute to functional challenges in PASC. This infection also elicits a long-lasting pro-inflammatory response that persists even after viral clearance, potentially correlated with brain fog. However, it is unclear whether pro-inflammatory responses and cognitive sequelae persist beyond 1 year after the onset of infection. Thus, this study sought to investigate the long-term consequences of PASC on EFs as well as a potential association with markers of inflammation. Forty individuals with PASC who passed performance validity testing (PVT) and 40 matched healthy controls (HC) underwent neuropsychological assessments, including the Montreal Cognitive Assessment to assess global cognition, Victoria Stroop Test to assess inhibitory control, Wisconsin Card Sorting Test to assess cognitive flexibility, Digit Span Task to assess working memory, and Mackworth Clock Test to assess sustained attention on the Psychology Experiment Building Language (PEBL) toolkit. Serum was assayed for tumor necrosis factor-? (TNF-?) and interleukin-10 (IL-10). Results indicate significant EF decline in PASC, inversely correlated with serum TNF-? concentrations, approximately 562 225 days after the onset of infection. Thus, there exists protracted EF decline in PASC, persistent even beyond 1 year after the onset of infection. Increased levels of TNF-? are observed to be associated with poorer executive functioning in PASC. 2025 Wiley Periodicals LLC.

Navigating the Autism Journey: Parental Experiences, Barriers and the Role of Early Intervention in India
subject: autism spectrum disorder; diagnosis; focus group; parental experiences; patient and public involvement; support services
description: Parents of children with autism spectrum disorder (ASD) often encounter significant challenges in accessing timely diagnosis and appropriate support services. This study explores the experiences of parents navigating autism-related services in India, focusing on barriers to diagnosis, post-diagnosis support and the role of early intervention. Using a qualitative research design, we conducted focus group discussions with 11 parents of children with ASD and analysed the data using thematic analysis. Sentiment analysis and chi-square statistical testing were also applied to assess parental perspectives across key themes. The findings reveal systemic delays in diagnosis, limited public awareness and inconsistencies in service availability, which contribute to heightened parental stress. Parents expressed difficulties in implementing intervention strategies at home and reported challenges related to accessibility and affordability of professional support. Whereas some parents acknowledged the benefits of available services, many highlighted gaps in tailored, culturally appropriate interventions. Sentiment analysis showed a relatively even distribution of positive, neutral and negative sentiments across themes, indicating the complexity of parental experiences. This study underscores the need for a more structured and inclusive approach to ASD support, including digital tools, peer support networks and early screening programmes. Strengthening policy frameworks and expanding accessible interventions can enhance the effectiveness of autism services and improve outcomes for families. These findings contribute to the growing body of research advocating for parent-inclusive, culturally responsive autism support systems. 2025 International Society for Developmental Neuroscience.

Digital Bridges: Harnessing Social Media for Social and Cultural Unity in Disaster Recovery
subject: cultural unity; digital bridge; disaster recovery; social cohesion; social media
description: This manuscript investigates the role of social media as digital bridges which link individuals, groups, and organizations within a?community in post-disaster recoveries. By synthesizing research from disaster studies, social capital theory, and digital communication literature, the paper draws on empirical evidence on social media supporting situational awareness, community mobilization, digital storytelling, and cross-cultural?solidarity. Simultaneously, it also?examines the problems of fake news, social media apartheid, surveillance dystopia, and the fleeting nature of online solidarity. Instead of a general literature review, the article provides an integrative conceptual synthesis that?connects theory to policy and practice. It concludes with concrete suggestions for policymakers, platform designers, and recovery specialists who want to leverage social media's connecting?power while reducing its separating dangers. 2026 Policy Studies Organization.

Associations Between Religious Coping and Anxiety Symptoms Among Emerging Adults in India: Religious Centrality as a Potential Moderator
subject: anxiety; ethnolinguistic identity; India; religious centrality; religious coping
description: Anxiety disorders are globally prevalent, with the highest disease burden in low- and middle-income countries. However, most research on protective factors of anxiety is predominantly conducted in high-income countries. Focusing on India, the most populous middle-income country where religion is salient, this study examined the association between religious coping and generalised anxiety symptoms and whether aspects of social identity moderated this association. A religiously and ethnolinguistically diverse sample of emerging adults (N = 484, Mage = 20.48 years) completed measures of religious coping, religious centrality and anxiety. Results indicated that negative religious coping was positively associated with anxiety symptoms, whilst positive religious coping was unrelated to anxiety. Religious centrality did not moderate the relation between religious coping and anxiety. However, ethnolinguistic identity (Northeastern vs. other regions) moderated the association, such that negative religious coping predicted higher concurrent anxiety among Indians from other regions, but not among Northeasterners. Findings support the role of negative religious coping in anxiety and suggest investigations into the role of ethnolinguistic identity as a critical contributing factor to mental health. 2026 The Author(s).

Collaborative Processes in the Development of the International Competences for Undergraduate Psychology (ICUP) Model
subject: basic psychological needs; competence model; group development theory; international collaboration; international foundational psychology competence; undergraduate psychology outcomes
description: Across all nations, undergraduate psychology programmes aim to promote the acquisition of foundational psychology competences. Yet, until recently, a universally recognised model outlining essential competences did not exist. The International Collaboration on Undergraduate Psychology Outcomes (ICUPO) addressed this gap by developing the International Competences for Undergraduate Psychology (ICUP) Model. The aim of this article is to provide guidance about how other groups might successfully approach similar efforts to delineate discipline-specific key competences. We describe the processes that led to the development of the ICUP Model, framed by group development theory (Preparing, Forming, Storming, Norming, and Performing Stages), with additional consideration of individual ICUPO Committee member psychological needs for competence, relatedness, and autonomy. Each group development Stage section (a) describes project activities relevant to the characteristics of that Stage, and (b) lists key strategies employed and lessons learned, as well as commentary on psychological needs. To further enhance the value of this endeavour, the Discussion includes (a) commentary on the strengths and limitations of these theories for understanding and enhancing the effectiveness of such project processes, and (b) actionable insights for educational leaders undertaking similar projects. 2025 The Author(s).

Dual-Phase-Lag Bioheat Analysis of Non-Fourier Thermal Wave Propagation in Multilayer Ocular Tissues
subject: dual-phase-lag bioheat model; human eye thermodynamics; non-Fourier heat conduction; porosity and perfusion effects; sensitivity analysis; surrogate modeling/reduced-order modeling; thermal safety assessment; thermal wave propagation
description: This study presents an advanced analytical framework for predicting thermal wave propagation in a multilayer ocular structure using the dual-phase-lag (DPL) bioheat formulation. The results confirm that non-Fourier thermal transport mechanisms are essential for accurately capturing transient heat behavior in biological tissues, particularly under external thermal exposure. Compared with classical Fourier and LordShulman models, the DPL model predicts smoother temperature gradients and lower peak thermal loads, thereby providing more physiologically realistic temperature distributions. The model validity regime analysis demonstrates clear operational boundaries where classical diffusion-based formulations fail and non-Fourier effects dominate thermal response. Sensitivity analysis reveals that ambient temperature and evaporation primarily control anterior ocular thermal behavior, while tissue porosity and blood perfusion significantly influence deeper layers such as the retina and sclera. Transient thermal comparisons confirm that classical models overpredict early-time heating due to the absence of relaxation effects. Multi-parameter response surface and thermal safety mapping highlight strong nonlinear coupling between environmental and physiological transport mechanisms, enabling quantitative identification of safe exposure limits. Additionally, surrogate modeling demonstrates high prediction accuracy relative to full DPL solutions while significantly reducing computational cost, enabling real-time thermal prediction and parametric optimization. Overall, the proposed hybrid analyticalcomputational framework establishes a robust platform for ocular thermal safety assessment, biomedical treatment planning, and environmental exposure risk evaluation. The findings also provide a generalized foundation for studying non-Fourier heat transport in layered porous biological media and support the development of next-generation predictive thermal modeling tools. 2026 Wiley P…

Influence of Sinusoidal and Non-Sinusoidal Two-Frequency Gravity Modulation in Viscoelastic Fluids Driven by Triple Diffusivity
subject: gravity modulation; nusselt number; sherwood number; triple diffusive convection; viscoelastic fluid
description: This study focuses on understanding the system's response to gravity modulation with two frequency components, characterized by both sinusoidal (sine wave) and non-sinusoidal (square, triangular, and sawtooth) waveforms, on three-component convection, considering a viscoelastic fluid modelled using an Oldroyd-B fluid. We apply the Venezian approach to evaluate the Rayleigh number, its corrected form, and the wave number by deriving a five-mode Lorenz model to investigate the onset of convection. A nonlinear analysis is conducted to investigate the dynamics of heat and mass transfer by solving an extended eight-mode Lorenz model, capturing higher order interactions. The onset of convection and the transport properties were observed to be influenced by combinations of sinusoidal and non-sinusoidal waveforms. This study optimizes convection-driven systems subjected to external periodic forcing by offering a more comprehensive understanding of convective instabilities in viscoelastic fluids. 2025 Wiley Periodicals LLC.
