    A Novel Multi-Step Numerical Framework for Ice Accretion Prediction Based on Unsteady Water Film Dynamics

    Ke Shen1,2,*, Dan Zeng1,2, Changhao Wang1, Lei Wang1, Yuliang Dong1

    Frontiers in Heat and Mass Transfer, Vol.23, No.6, pp. 1957-1980, 2025, DOI:10.32604/fhmt.2025.070396 - 31 December 2025

    Abstract Ice accretion on aircraft poses a critical threat to flight safety by significantly altering aerodynamic performance. This study presents a novel numerical framework for ice accretion prediction, developed by extending the Myers model and incorporating an advanced multi-step approach. The proposed framework integrates ice layer growth into the modeling of unsteady water film dynamics and introduces a revised criterion for determining the icing condition. A multi-step scheme, accounting for the continuous variation of physical parameters, is implemented to enhance computational accuracy. The framework is validated through simulations on both 2D and 3D configurations. For the… More > Graphic Abstract

    Ling Li1,#, Ninghui Xu1,#, Wenjing Wang2,*, Jianfen Ying1,*

    Journal of Psychology in Africa, Vol.35, No.6, pp. 833-842, 2025, DOI:10.32604/jpa.2025.071557 - 30 December 2025

    Abstract This study explores the role of teachers’ professional identity (TPI) on employee learning engagement (LE), with mediation by basic needs satisfaction (BNS). Participants were 255 Chinese pre-service teachers (191 females = 74.9%, 16 freshmen = 6.2%, 135 sophomores = 52.9%, 35 juniors = 12.5%, 72 seniors = 28.2%). They completed surveys on the “QuestionStar” online survey platform and 12 of the teachers completed interviews for sharing their personal insights. The results of Structural Equation Modeling (SEM) indicated that teachers’ professional identity significantly predicted both learning engagement and basic needs satisfaction, with basic needs satisfaction partially More >

    Abstract Background: In China, the policy of rotating teachers between urban and rural schools has been implemented to reduce educational disparities and ensure equitable access to quality education. These teachers face unique professional and emotional challenges during the rotation process, making their emotional labor a critical factor influencing their job performance. This study aimed to explore the relationship between rotating teachers’ emotional labor strategies and job performance. Methods: This study conducted a cross-sectional survey among 577 rotating teachers selected through stratified random sampling from primary and secondary schools in mainland China.

    A Unified Parametric Divergence Operator for Fermatean Fuzzy Environment and Its Applications in Machine Learning and Intelligent Decision-Making

    Zhe Liu1,2,3,*, Sijia Zhu4, Yulong Huang1,*, Tapan Senapati5,6,7, Xiangyu Li8, Wulfran Fendzi Mbasso9, Himanshu Dhumras10, Mehdi Hosseinzadeh11,12,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.145, No.2, pp. 2157-2188, 2025, DOI:10.32604/cmes.2025.072352 - 26 November 2025

    Abstract Uncertainty and ambiguity are pervasive in real-world intelligent systems, necessitating advanced mathematical frameworks for effective modeling and analysis. Fermatean fuzzy sets (FFSs), as a recent extension of classical fuzzy theory, provide enhanced flexibility for representing complex uncertainty. In this paper, we propose a unified parametric divergence operator for FFSs, which comprehensively captures the interplay among membership, non-membership, and hesitation degrees. The proposed operator is rigorously analyzed with respect to key mathematical properties, including non-negativity, non-degeneracy, and symmetry. Notably, several well-known divergence operators, such as Jensen-Shannon divergence, Hellinger distance, and χ2-divergence, are shown to be special cases More >

    Bibhuprasad Sahu1, Amrutanshu Panigrahi2, Abhilash Pati2, Ashis Kumar Pati3, Janmejaya Mishra4, Naim Ahmad5,*, Salman Arafath Mohammed6, Saurav Mallik7,8,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.145, No.1, pp. 1029-1054, 2025, DOI:10.32604/cmes.2025.069618 - 30 October 2025

    Abstract Metaheuristic optimization methods are iterative search processes that aim to efficiently solve complex optimization problems. These basically find the solution space very efficiently, often without utilizing the gradient information, and are inspired by the bio-inspired and socially motivated heuristics. Metaheuristic optimization algorithms are increasingly applied to complex feature selection problems in high-dimensional medical datasets. Among these, Teaching-Learning-Based optimization (TLBO) has proven effective for continuous design tasks by balancing exploration and exploitation phases. However, its binary version (BTLBO) suffers from limited exploitation ability, often converging prematurely or getting trapped in local optima, particularly when applied to… More >

    Yusheng Jian, Xiujiang Shi*, Xiaoxiao Li, Zehong Cai, Bailing Guan, Xiqun Lu

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.33, No.3, pp. 1-1, 2025, DOI:10.32604/icces.2025.011085

    Abstract The optimization of the lubricant supply quantity contributes to minimizing energy losses and wastage. Stearic acid is commonly used for boundary lubrication as an organic friction modifier. To enhance the performance of hydrodynamic bearings running with limited lubricant supply (LLS), under conditions of limited oil supply, the effect of stearic acid oiliness additive was studied on the relationship between oil film thickness of PAO10 (polyα-olefin) and inclination angle of the slider with an optical test rig for measuring the film lubrication in the slider-on-disc contact. The results showed that the film thickness presented an overall… More >

    Abstract Magnetohydrodynamic (MHD) radiative chemically reactive mixed convection flow of a hybrid nanofluid (Al2O3Cu/H2O) across an inclined, porous, and stretched sheet is examined in this study, along with its unsteady heat and mass transport properties. The hybrid nanofluid’s enhanced heat transfer efficiency is a major benefit in high-performance engineering applications. It is composed of two separate nanoparticles suspended in a base fluid and is chosen for its improved thermal properties. Thermal radiation, chemical reactions, a transverse magnetic field, surface stretching with time, injection or suction through the porous medium, and the effect of inclination, which introduces gravity-induced… More >

    Journal of Psychology in Africa, Vol.35, No.5, pp. 557-563, 2025, DOI:10.32604/jpa.2025.068969 - 24 October 2025

    Abstract This study investigated the role of work role engagement and interpersonal perspectives mediation in the relationship between school principal moral leadership and teachers’ voice behavior. A sample comprising 315 middle school teachers from a central province in China participated in the research (females = 73.3%). These teachers completed surveys on moral leadership, work engagement, trust in superiors, and voice behavior. The results of dual mediation modeling indicated evidence of an indirect effect of moral leadership on teachers’ voice behavior through work engagement. The results also indicated evidence of mediating effect of trust between moral leadership More >
