    Syndromic craniosynostosis (SC), such as Apert and Crouzon syndromes, causes midface hypoplasia that severely limits nasal cavity development. A computed tomography (CT)-based volumetric protocol for nasal cavity volumetry and choanal airway classification in pediatric SC patients, using landmark-based image segmentation software, is described and tested for intra-rater reproducibility. The protocol was applied to 10 SC patients (5 Apert, 5 Crouzon; 2-48 months; paired pre-/postoperative CT) and 10 reference children (60-168 months), not age-matched because CT is rarely indicated in healthy children. Intra-rater reliability was excellent (ICC = 0.987 and 0.909; 95% CI 0.934-0.997 and 0.689-0.976). Preoperative nasal cavity volume was significantly lower in SC patients (median 2,063.77 mm3; Q1-Q3 1,275.53-3,457.18) than in the reference group (median 35,502.13 mm3; Q1-Q3 28,811.21-39,167.15) (Mann-Whitney U = 0.000, Z = -3.780, p < 0.001). Nasal cavity volume increased between the paired CT scans in nine of ten patients (Wilcoxon Z = -2.701, p = 0.007; difference in medians +1,584.25 mm3; +76.8%), remaining at only 10.3% of the reference group median postoperatively. A weighted regression sensitivity analysis (log[Volume] vs log[Age], w = 1/Age; n = 10), accounting for the age disparity between cohorts, yielded an exploratory, model-based, non-normative estimate of 7,580 mm3 at the SC median age (8.5 months), extrapolated below the reference group age range; the SC median represented 27.2% of this estimate. Preoperative volume varied descriptively by choanal category (normal, stenosis, atresia) without tracking narrowing severity, possibly reflecting global hypoplasia; small subgroups precluded inferential testing. Nasal cavity volume is an anatomical measure and does not by itself indicate functional airway obstruction. The protocol offers a standardized workflow for larger, age-matched multicenter studies.

    This paper investigates the economic energy management of a wireless electric vehicle charging stations (EVCS) connected to hybrid renewable energy system comprising photovoltaic (PV), wind, battery storage, and the main grid. The study adopts an Improved Harris Hawk Optimization (IHHO) algorithm to optimize energy management and minimize operational costs under varying scenarios. Three distinct wireless EV charging load profiles are considered to evaluate the performance of the proposed optimization technique. Simulation results demonstrate that the IHHO algorithm achieves significant cost reductions and improves energy utilization efficiency compared to other state-of-the-art optimization algorithms such as Improved Quantum Particle Swarm Optimization (IQPSO), Honeybee Mating Optimization (HBMO), and Enhanced Exploratory Whale Optimization Algorithm (EEWOA). For scenarios with renewable energies, the IHHO algorithm reduced electricity costs by up to 36.41%, achieving a per-unit cost as low as 3.17 INR for the most demanding EV charging profile. Under scenarios of renewable generation disconnection, the IHHO algorithm maintained its superiority, reducing costs by up to 37.89% compared to unoptimized dispatch strategies. The integration of battery storage further enhanced the system's resilience and cost-effectiveness, particularly during periods of renewable unavailability. The IHHO algorithm's robust performance, reflected in its ability to handle dynamic and challenging operational conditions, demonstrates its potential for practical deployment in real-world wireless EVCS powered by hybrid renewable energy systems. The findings highlight the IHHO algorithm as a reliable and efficient tool for optimizing energy dispatch, promoting the integration of renewable energy, and supporting sustainable wireless EVCS infrastructure development. Simulation results demonstrate that IHHO outperforms all benchmark algorithms, achieving electricity cost reductions of up to 35.82% in EV Profile 3, with a minimum per-unit electricity cost of 3.11 INR/kWh across all scenarios. Specifically, IHHO achieved the lowest electricity cost of 6479.72 INR/day for EV Profile 1, 10,893.23 INR/day for EV Profile 2, and 20,821.63 INR/day for EV Profile 3, consistently outperforming IQPSO, HBMO, and EEWOA.

    Continuous real-time monitoring of non-cognitive markers is essential for the preliminary detection, control, and regulation of long-standing health conditions. Existing diagnostic techniques are frequently invasive and often not well suited for at-home monitoring, limiting their use in early detection of disorders. In this study, a flexible organohydrogel-based wearable sensor has been developed offering high accuracy and durability for real-time human health assessment. Employing a solvent co-cross linking strategy, a wrinkle texture organohydrogel is synthesized by combining polyacrylamide (PAm), and polymethylmethacrylate (PMMA) grafted onto the surface of cellulose nanocrystals (CNCs) through the free radical graft copolymerization technique. This innovative approach combines both physical and chemical interaction to eliminate mechano-chemical conflict and provide the organohydrogel with a balanced mechanical performance (2100% stretchability), toughness (519 kJ m-3), flexibility, conductivity ( 0.29 S m-1), remarkable adhesion, wide working range (-60 °C to 60 °C), and fast self-healing properties. In contrast to conventional hydrogels, this one-pot synthesis eliminates the need for metallic nanofillers, lowering cytotoxicity. In addition, PAm in combination with CNCs also provides biocompatibility, whereas sodium chloride makes the organohydrogel ionically conductive and sensitive. The engineered sensor exhibits enhanced efficiency, durability, and sensitivity and can be employed in haptic sensing technology.

    Microplastics (MPs) pose a major environmental challenge owing to their persistence and interactions with emerging contaminants (ECs). Their co-occurrence raises concerns about combined effects on aquatic ecosystems. MPs transport hydrophobic pollutants, affecting water quality. Studies show MPs can adsorb ECs at concentrations up to 106 times higher than their natural levels, increasing bioavailability. MPs and ECs accumulate in aquatic organisms, with evidence of trophic transfer. Their combined toxicity is often greater than their individual effects, causing physiological stress, reduced survival rates and microbial alterations, including enhanced antibiotic resistance. Beyond aquatic ecosystems, MPs and ECs pose risks to human health via bioaccumulation in the food chain. This review analyzes the mechanisms of interactions between MPs and ECs, including uptake, accumulation, and toxicity in aquatic organisms. These findings highlight the need for an integrated environmental impact assessment. Finally, future research directions are proposed, emphasizing key parameters to advance understanding in this field.

    This study investigates the effectiveness of using various agricultural waste ashes-namely eggshell ash (ESA), clamshell ash (CSA), cockle shell ash (CKSA), and oyster shell ash (OSA)-for the stabilization of expansive clay soils (ECS). Laboratory experiments assessed the impacts of these ashes on the soil's consistency limits, shrink-swell behavior, compaction properties, unconfined compressive strength (UCS), shear strength, and mineralogical and microstructural characteristics. The results demonstrated that the inclusion of agricultural waste ashes significantly improved the ECS properties by reducing plasticity from 29.6 up to 7.84%, increasing shrinkage limit from 15.55 to 33.06%, reducing free sweeling index from 57 to 39.66%, and enhancing UCS and shear strength from 114.64 to 1509.95 kPa. Microstructural analysis revealed the formation of cementitious compounds that contributed to a denser and more robust soil structure. This research highlights the potential of these waste materials in sustainable soil stabilization, supporting environmental conservation and infrastructure resilience while aligning with Sustainable Development Goals (SDGs).

    Perfluorooctanoic acid (PFOA) is a long-chain legacy congener of the per- and polyfluoroalkyl substances (PFAS) family, notorious as a "forever chemical" owing to its environmental persistence and toxic nature. Essential elements such as zinc (Zn) can cause toxic effects when they change their metal speciation and become bioavailable, such as zinc sulfate (ZnSO4). Combined toxicity assessment is a realistic approach and a challenging task to evaluate chemical interactions and associated risks. Therefore, the present study aims to elucidate the acute mixture toxicity (12-48 h) of PFOA and ZnSO4 in Daphnia magna at environment-relevant concentrations (ERCs, low dose: PFOA 10 μg/L ZnSO4 20 μg/L; high dose: PFOA 20 μg/L ZnSO4 50 μg/L) in terms of developmental impact, apoptosis induction, and interaction with major endogenous antioxidants. Our results showed that deformity rates significantly increased (p

    This study investigates the use of various industrial waste materials-silica fume (SF), cement kiln dust (CKD), calcium carbide residue (CCR), rice husk ash (RHA), and ground granulated blast furnace slag (GGBS)-as eco-friendly stabilizers for expansive clay soil (ECS). Laboratory tests were conducted to assess the impact of different proportions (3 %, 6 %, and 9 %) of these additives on the soil's physical, mechanical, and microstructural properties. Results indicated that the inclusion of industrial waste significantly improved the soil's behavior, with notable reductions in liquid limit (up to 37.66 %), plasticity index (up to 74.76 %), and swell potential. Additionally, unconfined compressive strength (UCS) and shear strength increased substantially, with UCS values rising from 114.64 kPa to 1582.91 kPa at 30 days of curing for 9 % GGBS. Microstructural analyses confirmed the formation of cementitious compounds, which enhanced soil particle bonding and durability. These findings suggest that industrial waste materials can serve as effective and sustainable alternatives to traditional soil stabilizers, offering both performance improvements and environmental benefits.

    An efficient trigonometrical-fitted two-derivative multistep collocation (TF-TDMC) method using Legendre polynomials up to order five as the basis functions, has been developed for solving second-order ordinary differential equations with oscillatory solution effectively. Interpolation method of approximated power series and collocation technique of its second and third derivative are implemented in the construction of the methods. Two-derivative multistep collocation methods are developed in predictor and corrector form with varying collocation and interpolation points. Later, trigonometrically-fitting technique is implemented into TF-TDMC method, using the linear combination of trigonometrical functions, to produce frequency-dependent coefficients in TF-TDMC method. The stability of the TF-TDMC method, with fitted parameters, is thoroughly analyzed and has been proven to achieve zero stability. Stability polynomials and regions for predictor and corrector of TF-TDMC method are developed and plotted. In the operation of the TF-TDMC method, initial conditions and the frequency for each problem (based on the exact solutions) are identified. The frequency-dependent coefficients are then adjusted according to the identified frequency. Predictor and corrector steps are implemented to estimate and refine the values of the dependent variable and its derivative, ensuring that convergence is achieved. A numerical experiment demonstrates that the proposed method significantly outperforms other existing methods in the literature, achieving the lowest maximum global error with moderate computational time across all step sizes for solving second-order ordinary differential equations with oscillatory solutions. Additionally, it effectively addresses real-world perturbed Kepler problems. The results include a detailed discussion and analysis of the numerical performance.•An efficient two-derivative multistep collocation method in predictor-corrector mode with trigonometrically-fitting technique (TF-TDMC) is developed for direct solving second-order ordinary differential equations with oscillatory solution.•TF-TDMC method has been proved to acquire zero-stability and its stability region is analyzed.•TF-TDMC method is the best among all selected methods in solving second-order ordinary differential equations with oscillatory solution, including perturbed Kepler problem.

    INTRODUCTION: The current study explored the influence of Chat Generative Pre-Trained Transformer (ChatGPT) on the concepts, parameters, policies, and practices of creativity and plagiarism in academic and research writing.

    METHODS: Data were collected from 10 researchers from 10 different countries (Australia, China, the UK, Brazil, Pakistan, Bangladesh, Iran, Nigeria, Trinidad and Tobago, and Turkiye) using semi-structured interviews. NVivo was employed for data analysis.

    RESULTS: Based on the responses, five themes about the influence of ChatGPT on academic and research writing were generated, i.e., opportunity, human assistance, thought-provoking, time-saving, and negative attitude. Although the researchers were mostly positive about it, some feared it would degrade their writing skills and lead to plagiarism. Many of them believed that ChatGPT would redefine the concepts, parameters, and practices of creativity and plagiarism.

    DISCUSSION: Creativity may no longer be restricted to the ability to write, but also to use ChatGPT or other large language models (LLMs) to write creatively. Some suggested that machine-generated text might be accepted as the new norm; however, using it without proper acknowledgment would be considered plagiarism. The researchers recommended allowing ChatGPT for academic and research writing; however, they strongly advised it to be regulated with limited use and proper acknowledgment.

    This systematic review evaluates studies focusing on parenting and feeding practices, children's feeding behavior, and growth stunting in Asian countries. Eight electronic databases were searched to screen studies published between Jan 2015 and May 2021. There were contradictory findings related to gender differences in growth stunting and factors that reinforce/facilitate or inhibit acquisition of optimum growth in children. Theme of parenting practices showed that time spent on childcare, traditional beliefs about child-care feeding and responsive feeding were also contributing factors. Amidst economic improvement, political, social changes, and worldwide execution of various nutritional programs, stunting continues to be relentlessly persistent and widespread in Asia. Undernutrition disturbs areas of the mind involved in reasoning, reminiscence, locomotor skills and also an adverse influence on the physical and psychological growth of children and ensuing learning capabilities. Stunted children have more anxiety and depression and lower self-esteem than non-stunted children. A public health strategy is required to: (i) properly examine stunting with time through collaborated efforts of community members and various sectors, (ii) tackle malnutrition with steps to enhance maternal nutrition during pregnancy, infant feeding practices and (iii) involvement of effective multi-sectoral partnership programs for management of stunting.

    This work demonstrates a label-free dual-sensing biosensor utilizing cascaded single-mode tapered fiber (SMTF) for the concurrent detection of Dengue II envelope (E) and SARS-CoV-2 spike (S) proteins. Two fiber tapers of different dimensions were employed in-line, with each taper functionalized with specific complementary antibodies to the targeted antigens. The cascaded interferometric effect yielded composite spectral output that exhibited discrete response toward localized refractive index changes due to binding of antigens and antibodies. Consistent red shifts were observed with increasing concentration of the targeted analyte, which led to sensitivity values of 6.91 nm/nM for SMTF1 and 9.96 nm/nM for SMTF2, with a detection limit of 0.1 pM. This dual-sensing platform demonstrates high sensitivity and specificity, rapid response times, and the potential for integration into portable diagnostic devices, presenting it as a promising tool for point-of-care diagnostics and simultaneous detection of multiple disease biomarkers.

    The transportation sector is the primary catalyst for environmental deterioration on a global level. Growing concerns about environmental issues caused by the overuse of fossil fuels in this industry have prompted countries to prioritize eco-friendly and energy-efficient vehicles. Electric and hybrid vehicles offer a potential solution to the global challenge of meeting carbon neutrality objectives, especially in the transportation sector. In this context, this study focuses on the comparative impact of technological development in conventional, hybrid, and electric vehicles on the load capacity factor (LCF) and carbon emissions (CO2) in the G7 countries over the period 2000-2021. For this purpose, the regularized common correlated effects (rCCE) approach is applied. The empirical outcomes indicate that (i) developments in conventional vehicles are detrimental to the environment; (ii) technological advancements in hybrid vehicles are ineffective in responding to carbon neutrality efforts; (iii) developments in electric vehicles contribute to environmental sustainability.

    To promote sustainable development and reduce fossil fuel consumption, there is a growing demand for high-performance, cost-effective, safe and environmentally friendly batteries for large-scale energy storage systems. Among the emerging technologies, zinc-air batteries (ZABs) have attracted significant interest. By integrating the principles of traditional zinc-ion batteries and fuel cells, ZABs offer remarkably high theoretical energy density at lower production cost compared to the current state-of-the-art lithium-ion batteries (LIBs). However, the critical challenge remains in developing high-performance zinc anode. Herein, this review provides a comprehensive analysis of the current status and advancements in zinc anodes for rechargeable aqueous ZABs. We begin by highlighting the major challenges and underlying mechanisms associated with zinc anodes including issues such as uneven zinc deposition, dendrite growth and hydrogen evolution reaction. Then, this review discusses the recent advancements in zinc anode modifications, focusing on strategies such as alloying, surface porosity and zincophilicity. By reviewing the latest research, we also identify existing gaps and pose critical questions that need further exploration to push the field forward. The goal of this review is to inspire new research directions and promote the development of more efficient zinc anodes.

    BACKGROUND: Infectious uveitis is a significant cause of visual impairment worldwide, caused by diverse pathogens such as viruses, bacteria, fungi, and parasites. Understanding its prevalence, etiology, pathogenesis, molecular mechanism, and clinical manifestations is essential for effective diagnosis and management.

    METHODS: A systematic literature search was conducted using PubMed, Google Scholar, Web of Science, Scopus, and Embase, focusing on studies published in the last fifteen years from 2009 to 2023. Keywords included "uveitis," "infectious uveitis," "viral uveitis," and others. Rigorous inclusion and exclusion criteria were applied, and data were synthesized thematically. Gene symbols related to infectious uveitis were analyzed using protein-protein interaction (PPI) networks and pathway analyses to uncover molecular mechanisms associated with infectious uveitis.

    RESULTS: The search from different databases yielded 97 eligible studies. The review identified a significant rise in publications on infectious uveitis, particularly viral uveitis, over the past fifteen years. Infectious uveitis prevalence varies geographically, with high rates in developing regions due to systemic infections and limited diagnostic resources. Etiologies include viruses (39%), bacteria (17%), and other pathogens, substantially impacting adults aged 20-50 years. Pathogenesis involves complex interactions between infectious agents and the ocular immune response, with key roles for cytokines and chemokines. The PPI network highlighted IFNG, IL6, TNF, and CD4 as central nodes. Enriched pathways included cytokine-cytokine receptor interaction and JAK-STAT signaling. Clinical manifestations range from anterior to posterior uveitis, with systemic symptoms often accompanying ocular signs. Diagnostic strategies encompass clinical evaluation, laboratory tests, and imaging, while management involves targeted antimicrobial therapy and anti-inflammatory agents.

    CONCLUSION: This review underscores the complexity of infectious uveitis, driven by diverse pathogens and influenced by various geographical and systemic factors. Molecular insights from PPI networks and pathway analyses provide a deeper understanding of its pathogenesis. Effective management requires comprehensive diagnostic approaches and targeted therapeutic strategies.

    This research investigates how despotic leadership influences follower creativity within the hospitality context. Grounded in social exchange theory (SET), the research delves into the mediating role of psychological safety in the link between despotic leadership and follower creativity. Additionally, it explores how power distance moderates this relationship, potentially alleviating the adverse implications of despotic leadership. By analyzing data collected from 447 employees in China, our findings reveal that despotic leadership behaviors diminish follower creativity. The results emphasize the crucial role of psychological safety as a mediating factor in this relationship. Furthermore, the study uses moderated path analysis to reveal that high power distance intensifies the negative impact of despotic leadership on psychological safety, further reducing employees' creativity. The research concludes with a discussion of the implications of these findings for both theoretical and practical applications.

    Physical activity (PA) is crucial for improving stroke survivors' health outcomes and quality of life (QoL). Impaired PA levels are common among stroke survivors, a significant portion of whom spend their days in sedentary occupations. Understanding the factors that influence physical inactivity and addressing the barriers to exercise participation can contribute significantly to improving stroke survivors' health outcomes and prognoses. Therefore, in the current review, we systematically searched five databases (PubMed/Medline, Scopus, SpringerLink, ScienceDirect and Google Scholar) for published studies reporting PA levels among stroke survivors, which yielded 301 potential articles. Based on the identification and screening processes recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR), 13 articles were finally included in the analysis. The results of these studies, covering 1,318 stroke survivors, revealed physical inactivity among most of the participants and significant heterogeneity among the outcome measures used. The factors affecting PA levels among stroke survivors were mainly categorised as physical, psychological, and sociodemographic, and all were significantly associated with PA levels after strokes.

    We examined the evidence for intermittent fasting (IF) as a preventative tool to influence β-amyloid in animal models of Alzheimer's disease (AD). A Scopus, Ovid, PubMed, and Web of Science (WoS), search yielded 29 results using the keywords "amyloid beta", "intermittent fasting", "intermittent caloric restriction", "alternate day fasting", "modified alternate-day fasting", "time-restricted feeding", "Ramadan fast", "intermittent calori* restriction", "intermittent restrictive diet", and "Alzheimer*". Five research articles addressed directly the effects of intermittent fasting on β-amyloid levels in animal models of AD: alternate day fasting (ADF) and time-restricted feeding (TRF) methods were incorporated in these studies. The study designs were found to be heterogeneous. Variations in the levels of β-amyloid peptides or plaque in either the hippocampus, cortical areas, or both in animals following dietary intervention were observed as compared to the ad libitum group. Non-significant changes were observed in three studies, while two studies interestingly demonstrated amelioration and reduction in β-amyloid levels. Given the conflicting results obtained from this study, significant care has to be taken into consideration before the protocol can be applied as a preventative approach to treat Alzheimer's disease. Longitudinal research is warranted to fully grasp how dietary habits can help alleviate the disease either through upstream or downstream of AD pathology.

    The risk factors for stunting incidence involve categorical data in both the response and predictor variables. Therefore, we developed a sparse categorical principal component logistic regression model capable of handling data with multicollinearity. The parameters of the sparse categorical principal component logistic regression model were estimated using the maximum likelihood method and the Newton-Raphson iterative approach. The analysis yielded a likelihood ratio value of 144.81 and a chi-square statistic value of 11.07, indicating that all factors included in the model are statistically significant. The results highlight that medical history, inadequate complementary feeding, formula feeding, lack of complementary feeding programs, and lack of iron supplementation for mothers are highly associated with the risk of stunting in toddlers. This emphasizes the need for attention to maternal nutrition from pregnancy through breastfeeding, as well as the nutrition of the toddler. Some important points proposed in this method are:•Stunting data consists of categorical variables containing multicollinearity.•The method applied is sparse logistic regression combined with categorical principal component analysis.•Analysis of risk factors for stunting in toddlers is based on the child's own condition, as well as parental factors, namely age, education, and intake of additional food and supplementary tablets during pregnancy.
