Geochemical profiling, pedogenesis, and paleoclimate: Understanding stone age archaeological context of Dulung River Valley, Eastern India

Fluvial sediments in Eastern India hold rich archaeological deposits, Lower Palaeolithic to Neolithic artifacts. Traditionally, studies of these sediments relied on qualitative analysis of their stratigraphy and morphology. This article advocates for a shift towards a Quaternary...

Model-dependent Galactic Environment Effects on Multitransonic Accretion and Emergent Acoustic Gravity around Kerr Black Holes

Abstract The hydrodynamics of low-angular-momentum, multitransonic, axisymmetric, inviscid accretion flow onto a rotating black hole in presence of a galactic environment has been systematically investigated in detail using three standard disk geometries and two thermodynamic equ...

A Comparative Analysis of Classical Biometrics and AI‐Driven Models for Yield Prediction in Brinjal ( Solanum melongena L.)

Optimizing yield stability in brinjal ( Solanum melongena L.) remains a challenge, as traditional biometric methods struggle to capture the complex, nonlinear trait interactions governing productivity. This study evaluates the biological information gap inherent in traditional bi...

Reflected intensity noise for laser diode to cylindrical microlens on the elliptical core step index fiber

Abstract The trustworthiness of the laser-to-fiber coupling is one of the main issues in optical communication technology. However, various types of misalignment lower the coupling efficiency (CE) in fiber-to-lens coupling. The lateral asymmetry also results in an unexpected nois...
