Angular Dependence of Magnetoresistance with Twofold and Fourfold Symmetries and a Large Topological Hall Effect in a Ferrimagnetic Mn2SbBe0.1 Single Crystal

Abstract Ferrimagnetic intermetallics with inequivalent magnetic sublattices host rich magneto-transport properties arising from competing interactions and anisotropy. We report on a Mn2SbBe0.1 single crystal, where interstitial Be tunes the anisotropic response under strong in-p...

Hydrogen rich producer gas generation from coal Co-gasification with dual biomass feedstock in a downdraft fixed bed gasifier: Experimental study and RSM optimization

The increasing global demand for energy, driven by population growth, highlights the need for sustainable and efficient energy conversion technologies. Gasification has emerged as a promising approach for converting low-grade coal into valuable gaseous products. In this study, th...

Trimetallic Cu–Zn–Fe Layered Double Hydroxide Nanocarrier Enabling On-Demand Anticancer Drug Release with Prolonged Therapeutic Windows for Precision Oncology

Clinical oncology faces a critical technological bottleneck driven by the rapid emergence of therapy-resistant tumors. Melanoma, in particular, remains a highly aggressive malignancy with pronounced metastatic potential and poor responsiveness to traditional therapy, signify the...

Nested spatial processes in urban food delivery: How scale and boundary choice shape built-environment relationships in New Delhi, India

Platform-mediated food delivery demand concentrates last-mile freight, yet planning aggregates it into zonal units, introducing Modifiable Areal Unit Problem (MAUP) distortion. Even though increasing literature on MAUP in freight literature exists, its impact on digital delivery...

Defect Enhanced Charge Transport in Functional BaSnO3:La/rGO Heterostructures for Electromagnetic Interference Shielding Application

The increase in wireless networks and smart devices has led to a significant rise in Electromagnetic Interference (EMI), highlighting the need for functional materials to effectively reduce it. In this work, Ba 1-x La x SnO 3 (x = 0.00-0.03), synthesized via a solid-state route,...

Green-light-activated Os(II) metallo-photoantibiotics for antibacterial therapy and infected wound healing

The emergence of antibacterial resistance and persistent bacterial biofilms challenges conventional antibacterial therapies for infected wounds, while antibacterial photodynamic therapy offers a promising alternative. To address these challenges and explore the unknown potential...

Revival of Riverine Wetlands through Re-Establishing Longitudinal Connectivity of Extinct River Systems

The Indo-Gangetic Plain exhibits a number of riverine wetlands associated with extinct rivers in the form of interconnected channels, oxbow lakes, meander scars, etc. To develop a model for the revival of these riverine wetlands, the interfluvial zone of the Ganga and Sai Rivers...

Near-Surface Lunar Plasma Characteristics Derived from Chandrayaan-3 RAMBHA-LP Measurements

Abstract We present an independent analysis of near-surface lunar plasma parameters derived from the RAMBHA-LP payload aboard the Chandrayaan-3 lander during daytime operations from August 24 to September 3, 2023. Although Manju et al. (2025) already provided a detailed character...

Newton method for set optimization problems with set-valued mapping of finitely many vector-valued functions

In this paper, we propose a Newton method for unconstrained set optimization problems to find their weakly minimal solutions with respect to lower set-less ordering. The objective function of the problem under consideration is given by finitely many strongly convex twice continuo...

Study of Cu3SbS4/Sb2S3 photothermal heterostructure coating for enhanced solar still desalination performance with durability analysis

Passive Solar Stills are an alternative method of producing fresh water in a decentralized manner. However, they suffer from being limited due to the low broadband solar absorptivity of typical basin materials. In this study we present the synthesis, characterization and photothe...

Machine Learning-Based Prediction of Land Surface Temperature in a Mining-Intensive Region Using Google Earth Engine

This study examines the spatiotemporal dynamics of land surface temperature (LST) across Chhattisgarh, India, one of Asia’s largest coal-mining regions, from 1 January 2023 to 1 January 2024, using Google Earth Engine and a multi-variable dataset comprising NDVI, Albedo, Elevatio...

Thermal–Hydraulic Performance Analysis of Micro Pin‐Fin Heat Sinks With Different Fin Geometries: A Numerical Study

Asymptotic identities for Jacobi polynomials via spectral geometry of rank-one symmetric spaces

Radial eigenfunctions of the Laplace-Beltrami operator on compact rank-one symmetric spaces may be expressed in terms of Jacobi polynomials. We use this fact to prove an identity for Jacobi polynomials which is inspired by results of Minakshisundaram-Pleijel and Zelditch on the F...

Zooming in on ‘bi-large’ neutrino mixing with the first JUNO results
