Kernel sensitivity and robust optimal control for Banach-valued weakly singular Volterra systems

We study kernel sensitivity and robust optimal control for Banach-space-valued Volterra systems whose memory kernels may have integrable diagonal singularities. A kernel space based on continuous causal sections provides the topology for perturbing the entire memory law. We estab...

A Fuzzy Multi-Criteria Decision-Making Framework for Optimal Mining Method Selection in Complex Geological Conditions

Mining Method Selection (MMS) is a complex, multi-criteria decision-making problem influenced by geological, technical, economic, environmental, and safety factors. Traditional methods, such as Nicholas, University of British Columbia (UBC), and reformed UBC approaches, rely on e...

Optimizing pre-listening activities with AI-assisted priming for L2 listening comprehension

As second language (L2) listening presents significant real-time processing challenges for less competent L2 learners, pre-listening activities provide them with the much-needed mental scaffolding. Recent research has suggested that augmenting top-down predictive processing could...

Computational identification of potential inhibitors for chikungunya virus nsP2pro

Abstract Chikungunya virus remains a crucial global health issue with no approved therapy available. In particular, the viral replication is associated with the non-structural protein 2 protease (nsP2pro). In this study, possible inhibitors for nsP2pro from the National Cancer In...

Molecular dynamics reveals functional group control of Rhodamine B hydrochar adsorption

Abstract This study elucidates the molecular mechanisms of Rhodamine B (RHB) dye removal from aqueous solution using hydrochar adsorbents through comprehensive molecular dynamics simulations. Three model hydrochars were evaluated across a wide range of concentrations: mixed oxyge...

Calderón-Zygmund gradient estimates for p-Laplace systems with BMO complex coefficients

This work is concerned with global gradient bounds for a class of divergence-form degenerate elliptic systems with complex-valued coefficients. Notably, the leading coefficients are merely required to be sufficiently small in BMO, which is strictly weaker than the VMO condition....

Sub-cell-free weighted least-squares integration methods with and without stabilization terms for higher-order shear deformation analysis of isotropic plates

ABSTRACT This paper presents a sub-cell-free weighted least-squares integration (SCF-WLSI) framework for higher-order shear deformation analysis of isotropic plates, formulated in two variants: un-stabilized (u-SCF-WLSI) and stabilized (s-SCF-WLSI). Advancing the estimation-based...

Macroeconomic Determinants of Housing Prices in Malaysia: Evidence from Time-Series Econometric Analysis

This study examines the effects of population, unemployment rate, construction costs, income per capita, and interest rates on housing prices using annual data from 1990 to 2024. Adopting time series econometric analyses, including stationarity, the ARDL model, VAR, Granger causa...

VietLegalLM: Progressive Legal Expertise Through Synthetic Comprehension and Reinforcement Learning

Legal AI systems require accuracy and verifiable reasoning, yet under-resourced languages lack the specialized models needed to meet these standards. This challenge is particularly acute for statute-based civil law systems like Vietnam’s, where the core task is interpreting and a...

The development and contributions of secondary ecological succession to protecting eroding mangrove dominated muddy coasts: evidence from the vietnamese mekong delta

Recent literature reveals that the ecological restoration of eroding mangrove-dominated muddy coasts (MDMCs) requires human intervention. However, there is limited information regarding secondary ecological succession (SES) in abandoned MDMCs. The Vietnamese Mekong Delta (VMD) co...

Effects of ultrasound-assisted freezing on drying kinetics, mass transfer and quality of freeze-dried Abelmoschus sagittifolius root

Freeze-drying is widely recognized as an effective technique for preserving thermolabile medicinal materials. In practice, the long drying period can significantly increase both energy consumption and operating expenses. This study investigated the effects of ultrasound-assisted...

Enhanced FOC performance using a hysteresis current controller for EV induction motor drives

Electric vehicle traction drives require fast, robust, and efficient induction motor control, especially under variable speed, load torque, and thermal operating conditions. In Field-Oriented Control integrated Hysteresis Current Controller (FOC-HCC) induction motor drives, varia...

One-step method for preparation of Fe3O4/g-C3N4 composite using hydrazine for heterogeneous photocatalysis

Environmental pollution and the global energy demand have significantly increased, necessitating sustainable development strategies, with advanced functional materials emerging as key solutions. Specifically, photocatalysis technology has attracted considerable attention due to i...

From gamification to work performance: a two-wave, two-study examination of psychological needs and meaningful work of employees in China and Singapore

Purpose Organisations are increasingly adopting gamification as a strategy to enhance employee motivation, engagement, and performance. While prior research has primarily examined gamification as an organisational tool, this study shifts the focus to how employees experience gami...

Secure and reliable SWIPT in active RIS-aided downlink NOMA with hardware impairments

Abstract Due to growing system complexity and the vulnerability of wireless transmissions to information leakage, maintaining secure and private communication in sixth-generation (6G) networks continues to be a significant problem. By enabling wireless power transfer to distant I...

Deconvolution of cumulative distribution function from repeated measurements with uniform noises

This work is devoted to the estimation of a cumulative distribution function (CDF) using repeated measurements contaminated by additive noise. The noise is assumed to follow a uniform distribution on [−S,S] with an unknown S>0. Since the characteristic function of the noise exhib...
