Kyrgyzstan relies heavily on hydropower generation, which results in a pronounced seasonal mismatch between electricity supply and demand, posing significant challenges to power system reliability and supply security. During winter, reduced hydropower availability and increased electricity consumpti...

This study investigated the distribution and trophic transfer of copper (Cu) and zinc (Zn) from two freshwater fish species (Channa punctatus and Mastacembelus armatus) to the piscivorous bird Halcyon smyrnensis in River Kalpani, Pakistan. Samples collected from five sites between December 2017 and...

Polymer-derived carbons have emerged as efficient and economical electrocatalysts for energy-related reactions such as oxygen reduction and hydrogen evolution. However, their performance often faces an inherent trade-off between porosity and electronic conductivity, necessitating precise regulation...

Pakistan's `50 Million Olive Tree Tsunami' targets ~10 million acres of olive expansion by grafting commercial cultivars onto wild Olea ferruginea rootstocks, but physiological/ecological impacts are unknown. This 2023--2025 field study sampled 450 trees across three Balochistan sites (wild: \( n =...

Maternal mortality risk in Bangladesh remains a critical public health challenge, compounded by rural access gaps and the absence of scalable, data-driven early-warning systems. This study presents a reproducible, interpretable machine learning framework for maternal health risk classification using...

Singapore’s primary and secondary science education is widely recognized for its high performance through systemic reform. The synergistic innovation of its curriculum philosophy, textbook content, and assessment mechanisms warrants in-depth investigation. In terms of curriculum philosophy, Singapor...

As adversaries deploy advanced persistent threats (APTs), social engineering, and credential-stuffing attacks to circumvent classical reactive defenses, identity security faces a formidable challenge. This paper proposes GHOST (Game-theoretic Honeytoken Optimization for Strategic Threat Detection),...

Vortex beams carrying orbital angular momentum enable a new multiplexing dimension for optical wireless communications. However, atmospheric turbulence induces beam broadening, intensity scintillation, beam wander, angle-of-arrival fluctuations, and OAM crosstalk, degrading propagation performance....

Hydrocarbon reserve estimation and reservoir characterization remain critical aspects of field development planning, particularly in mature offshore basins such as the Niger Delta. This study integrates 3D seismic interpretation with petrophysical analysis to evaluate reservoir quality and estimate...

Injected water quality critically determines waterflooding effectiveness. The southern area of Gaoshen, a major deep reservoir block of the Gaoshangpu Oilfield (Jidong Oilfield), faces severe injection-well plugging, increased injection pressure, failing injection rates, and rapid production decline...
