Abstract The remediation of viscous oil spills and organic contaminants in harsh environments requires sorbents that possess not only adsorption capability but also exceptional thermal and chemical stability. Herein, we report the facile synthesis of a novel class of fluorinated copolyimine xerogels (XG-CoPI) following the solvent exchange method via the polycondensation of terephthalaldehyde (PA), 4,4′-oxydianiline (ODA),...

Abstract In this paper, we study the structure of locally generalized radical subgroups of the general skew linear group GLn(D) of degree n ≥ 1 over a division ring D. Among results, we show that if G is a locally generalized radical almost subnormal subgroup of GLn(D), then G is central provided D is not a locally finite field in case n...

Abstract In this study, endospore-forming bacteria were isolated, screened, and characterized from samples collected in Tan Phu protection forest for potential use in biofertilizer application. Twelve endospore-forming bacteria showed the ability to produce indole-3-acetic acid were evaluated. Based on the relative enzyme activity, siderophore production, phosphate and potassium solubilization, strain CN12 was selected. Strain CN12...

Abstract Ho Chi Minh City (HCMC), one of Southeast Asia’s fastest-growing megacities, has expanded its road networks, sluice gates, and flood-control structures in response to rapid urbanization and rising climate risks. While these grey-infrastructure interventions aim to protect the city, they have increasingly altered natural hydrological processes by reducing permeable surfaces, fragmenting wetlands, and obstructing...

Abstract EUV lithography is advancing towards high productivity and yield, but the thickness of the interface diffusion layer and surface roughness in Mo/Si multilayer mirrors critically impact optical performance, presenting a major obstacle. This work presents a comprehensive study on controlling the ion beam sputtering deposition parameters to optimize the interface quality, roughness, and microstructure...

Abstract In this letter, we study the average block error rate (BLER) performance of short-packet communications (SPC) for pinching-antenna systems (PASS). A base station equipped with a pinching antenna serves an Internet of Things downlink user using SPC. Closed-form expressions for the average BLER of SPC for PASS networks are analytically derived under in-waveguide attenuation....

Abstract Deep learning has demonstrated remarkable success across domains such as image, audio, video, and text processing. However, its application to tabular data remains challenging due to the heterogeneous nature of features and the lack of positional information, which complicates feature interaction modeling. While deep learning approaches for tabular data have achieved performance levels comparable...

Abstract The sol–gel technique offers a versatile route for synthesizing electrode materials with reduced and uniform grain sizes, enabling the development of high-performance cathodes for next-generation sodium-ion batteries (SIBs). Achieving high-performance layered oxide cathodes requires control over chemical homogeneity and phase composition. Herein, we investigate the feasibility of tuning the structural integrity, electrochemical behavior, and...
