Exact Traveling Wave Solutions of Extended Kadomtsev–Petviashvili Equation via Modified Rational Sine–Cosine and New Extended Direct Algebraic Methods

This paper investigates the (2 + 1)–dimensional extended Kadomtsev–Petviashvili equation (eKPE), importantly describing multidimensional nonlinear wave phenomena. Its exact traveling wave solutions are constructed using the modified rational sine–cosine method and the new extende...

Microbial Oils from Tropical Fruit-Derived Oleaginous Yeasts: Lipid Profiles and Predicted Biodiesel Potential

Microbial oils produced by oleaginous yeasts are promising renewable lipid resources for biofuel and other biotechnological applications. Tropical fruits may harbor diverse yeasts with the capacity to accumulate intracellular microbial oils, but their lipid profiles and biodiesel...

Experimental and Modeling Investigation of Interfacial Effects on the Mechanical Properties of Iron‐Oxide‐Particle‐Reinforced Acrylonitrile–Butadiene–Styrene Composites for Extrusion‐Based Additive Manufacturing

ABSTRACT Waste iron oxide particles generated during steelmaking were proposed as promising reinforcements for enhancing the mechanical properties of acrylonitrile–butadiene–styrene (ABS)‐based composite filaments for extrusion‐based additive manufacturing. The surface chemical s...

Immunomodulatory Potential of KSTM in Activating Natural Killer Cells for Cancer Cell Elimination

Background/Objectives: Cancer remains a major cause of mortality worldwide, and resistance to therapy continues to limit treatment success. Improving the susceptibility of cancer cells to immune-mediated killing, particularly by natural killer (NK) cells, may enhance therapeutic...

Derivation of Analytical Solution to ARL Integral Equation of the Extended EWMA Control Chart for Time Series ARMAX Process

Control charts are effective tools in statistical process control that are used for monitoring process quality and detecting unusual changes. The extended exponentially weighted moving average (extended EWMA) control chart is one of a traditional EWMA-type improvement which showe...

From Green Policy Ambition to Investment-Ready Projects: Integrating Microeconomic and Policy Implementation Perspectives in Thailand

Thailand has introduced a broad policy architecture to support green industrial development, yet policy support does not automatically translate into commercially viable and socially desirable projects. Using Thailand as an institutionally grounded application rather than as empi...

A Two-Sex Mathematical Model of Sterile-Male Releases for the Suppression of Anopheles Mosquito Populations

This study develops a deterministic two-sex compartmental model to investigate the population-level effects of continuous sterile-male releases on Anopheles mosquitoes. The model distinguishes aquatic stages, unmated females, fertile-mated females, sterile-mated females, wild mal...

Valorization of Modified Residual Durain Peel Biochar Loaded in Composite Beads for Enhancing Cu(II) Removal: Optimization and Performance Evaluation

Abstract Sustainable wastewater treatment requires the development of efficient adsorbents derived from agricultural residues. The durian peel biochar (B-DP) was proposed as a residual biomass adsorbent for such purposes. In this study, B-DP was activated its functional groups us...

Effect of hybrid layer dominance on mechanical performance, moisture diffusion, and biodegradation of kenaf/pineapple leaf fiber-reinforced PLA laminated biocomposites

Abstract Hybrid natural fiber-reinforced biocomposites can be sustainable materials for lightweight engineering, but the impact of layer dominance on the multifunctional performance of such biocomposites is still poorly known. This study focused on kenaf fiber (KF) and pineapple...

The Development of Human Resource Middle-level Executives’ Potential Model in Public Limited Companies for Business Competitiveness in the Digital Era

The rapid advancement of digital technologies and artificial intelligence has increased governance complexity and workforce transformation in Thailand's public limited companies. This study aims to (1) identify the key competency components of human resource (HR) middle-level exe...

A New Nakagami–Weibull Non-Mixture Cure Model with Applications to Right-Censored Survival Data

Cure fraction models provide a useful framework for analysing survival data in which some individuals may never experience the event of interest. This paper introduces a flexible Nakagami–Weibull Non-Mixture Cure (NWNMC) model for right-censored survival data with a long-term sur...

Tribological and acoustic evaluation of non-asbestos copper-free automotive brake pads with olefin elastomers

Purpose This study aims to develop and evaluate copper-free brake pads using an olefin-based elastomer as an alternative to conventional nitrile butadiene rubber (NBR)-based formulations. This research also benchmarks the newly developed pad against the commercial brake pad to de...

Ballistic Resistance of Fiber-Reinforced Cement Composite: A Critical Review

This review examines the ballistic resistance of fiber-reinforced cement composites (FRCs) and related cementitious systems for protective structures, with emphasis on projectile–target interaction, penetration and scabbing mechanisms, and the governing roles of material and stru...

Lightweight Shoulder Physiotherapy Exercise Recognition via Efficient Channel Attention and Depthwise Separable Residual Networks on Wrist-Worn IMU

Accurate and subject-independent recognition of shoulder physiotherapy exercises from wrist-worn inertial measurement unit (IMU) signals is essential for automated home-based rehabilitation monitoring, yet existing deep learning models are too parameter-intensive to deploy on res...

Polynomial Stability of the Timoshenko Beam System with a Fractional Dynamic Boundary Feedback

We investigate the asymptotic behavior of a Timoshenko beam system in which the free end carries a tip mass subject to a restoring spring force and a tempered Caputo fractional damping force with parameter η>0 (the case η=0 is left as an open problem). Using a diffusive state...

Mechanical-press torrefaction of Napier grass for bio-coke production: effects of temperature and pressure on densification, fuel properties, and CO2 gasification behavior

This study investigated a mechanical-press torrefaction-assisted carbonization route for producing Napier grass-derived bio-coke. Napier grass was first torrefied under mechanical pressure at 280–340 °C and 20–70 MPa, followed by carbonization at 1000 °C. The effects of torrefact...

Analytical design of ARL based on a modified EWMA control chart under ARIMA processes
