Multi-head attention-driven multimodal feature integration network for autism spectrum disorder detection

The growing prevalence of Autism Spectrum Disorder (ASD) highlights the need for accurate and reliable intelligent screening systems for early behavioral assessment. However, ASD-related behaviors vary significantly across individuals, making diagnosis based on a single modality...

Preparation of gold nanoparticles supported on microcrystalline cellulose by solid-mortar grinding and their catalytic activities

A solid-grinding approach for transforming microcrystalline cellulose into less ordered matrices, followed by the deposition of a high density of gold nanoparticles (NPs) without employing environmentally toxic chemicals, solvents, or external reducing agents is reported. The gen...

In vitro antioxidant activity and cytotoxic effects of sulfated galactan polysaccharides from Gracilaria spinulosa

This study investigated the extraction, chemical composition, structural characteristics, antioxidant activity, and in vitro cytotoxic potential of sulfated galactan polysaccharides (SGP) isolated from the red seaweed Gracilaria spinulosa collected from the Gulf of Mannar, Tamil...

Enhanced ionic conductivity in a sustainable eucalyptus gum-chitosan biopolymer electrolyte for electrochemical device applications

Polymer electrolytes, owing to their distinct characteristics, present a viable alternative to liquid electrolytes in batteries. This study presents a biodegradable polymer electrolyte membrane composed of a blend of eucalyptus gum (EG), chitosan (CS), and ammonium thiocyanate (A...
