The impact of the entropy parameter in generalized information measures for image quality assessment

We introduce and study Mathai’s cumulative residual entropy, a generalized entropy measure motivated by Mathai’s entropy. We establish fundamental properties, including finiteness, limiting behavior, and connections with existing cumulative residual entropy measures. The entropy...

Improving Slow-Roll Estimates in Starobinsky Inflation Using an Analytic Hubble Parameter

Abstract Inflationary observables are naturally formulated in terms of the Hubble-flow hierarchy. Because exact background solutions are often unavailable, the Hubble-flow parameters are commonly approximated using potential slow-roll (PSR) quantities constructed from derivatives...

Report on the Occurrence of Anisakid Nematodes in Commercial Fish from the Southwestern Indian Waters

Anisakid nematodes are zoonotic parasites with a heteroxenous life cycle involving diverse hosts across multiple trophic levels in the marine ecosystem. Anisakiasis represents a significant global public health issue, with numerous clinical cases documented across the regions whe...

Hybrid Hexagonal Boron Nitride and Few‐Layer Graphene Incorporated XNBR ‐ NR Blends With Enhanced Oil Resistance, Mechanical, and Antibacterial Properties

ABSTRACT Latex blends of carboxylated nitrile‐butadiene rubber (XNBR) and natural rubber (NR) were prepared at different blend ratios, and the optimized 50:50 (phr) blend was reinforced with mono‐ and hybrid fillers of h‐BN and FLG, making it suitable for dip‐molded products. Sca...

Analysis of Dynamic Mechanical Responses of Carbon Black Filled Natural Rubber Composites Using Shear and Tensile Testing

ABSTRACT Natural rubber / high abrasion furnace (HAF) carbon black were prepared, and the frequency‐ dependent dynamic mechanical properties were investigated. Dynamic mechanical characterization was carried out using both Rubber Process Analyzer (RPA) and Dynamic Mechanical Anal...

Sustained vane rotation in a circular ratcheted Leidenfrost engine

This study investigates a vane-driven Leidenfrost engine based on evaporation-induced self-propulsion of liquid volumes of deionized water on a radially ratcheted circular substrate. Asymmetric surface topography rectifies vapor flow beneath the levitated liquid, creating pressur...

Diagnosing CESM2 Biases in Northwest Indian Ocean Warming and Its Implications for India Summer Monsoon Precipitation

Abstract Declining monsoon rainfall over agriculture‐dependent Eastern Central India (ECI) during 1901–2014 threatens regional food and water security. Observations link ECI drying to rapid Northwest Indian Ocean (NWIO) warming, which weakens monsoon circulation. However, the wid...

Distribution of surface layer temperature inversion in the North Indian Ocean and associated acoustic propagation characteristics

Surface Layer Temperature Inversion (SLTI), a warm layer between the surface and subsurface colder waters, is a significant oceanographic feature that has a profound impact on the oceanic acoustic propagation. Strong inversions are observed in northern BoB and in the South Easter...

Converging pathomechanisms link SARS-CoV-2 infection with major neurodegenerative diseases

Neurological complications are among typical clinical manifestations, both during the acute phase of SARS-CoV-2 infection and long-term post-acute COVID-19 sequelae, i.e., Long COVID. A growing body of evidence connects SARS-CoV-2 infection to systemic inflammation, peripheral im...

Triclosan Induces Oxidative Stress, Gene Expression Changes, and Cardiomyocyte Dysfunction in Magallana bilineata Heart Cell Cultures

ABSTRACT Triclosan (TCS) is an antimicrobial compound widely used in pharmaceutical and personal care products (PPCPs). It is classified as a contaminant of emerging concern (CEC) due to its environmental health implications. However, significant knowledge gaps remain regarding t...
