Tele-Optometry and Mobile Eye Care Units: A Rural Vision Care Model for India

India accounts for about 20% of the world’s visually impaired population. Rural and underserved populations are disproportionately affected by avoidable causes of blindness such as uncorrected refractive errors, cataracts, diabetic retinopathy, and glaucoma. Traditional facility-...

Geometric and wave optics analysis of BTZ-like charged wormholes with disclinations

We study the geometric and wave-optical properties of a charged BTZ wormhole (BTZCWH) spacetime carrying disclinations. The metric function \(f(r)=1-b_0/r-\mathcal {Q}^2 r^2/4\) has two positive zeros, an inner throat \(r_0\) and an outer zero \(r_*\) ; the static Lorentzian desc...

DASTNet-X: an explainable dual-attention based spatio-temporal network for arrhythmia classification

Deep learning (DL) models have demonstrated strong performance in electrocardiography (ECG) arrhythmia classification. However, the criteria and processes for selecting ECG samples for analysis are often unclear. This lack of transparency, together with the challenge of interpret...

A Bioactive Fraction of Euphorbia antiquorum Stem Powder Ameliorates High‐Fat High‐Fructose Diet/Streptozotocin‐Induced Diabetes via GLUT‐4 Modulation

Euphorbia antiquorum L. (Euphorbiaceae), a traditionally used Asian medicinal plant, was systematically evaluated for its antidiabetic efficacy through a bioactivity-guided approach integrating in vitro, in vivo, and in silico studies. Among the four solvent fractions of the etha...
