TiO2/PdO-based eye-detectable fast-responding sensor to address H2 safety infrastructure: Unveiling the colour change mechanism and active sites

Deployment of hydrogen-based infrastructure is impeded by the difficulty of real-time detection of hydrogen leaks. To address this issue, a TiO 2 /PdO composite chemochromic hydrogen sensor is optimized by tuning TiO 2 particle size and Pd precursor concentration to achieve rapid...

Phonon-Assisted Photoluminescence and Ultrafast Exciton Dynamics in Two-Dimensional Silicon Carbide

Phonon-assisted photoluminescence provides a direct window into exciton-phonon interactions in semiconductors. Using fully ab initio many-body perturbation theory, including finite-momentum Bethe-Salpeter calculations, we investigate phonon-assisted emission and exciton dynamics...

Extrapolating CSR–HRM interdependencies and employee well-being for sustainable workplaces in generative AI era

The development of generative AI (GAI) capabilities has led corporate entities to rethink their strategic initiatives towards sustainable workforce management. This dynamism has been broadly identified as a concern for managerial teams. Despite strong consensus on the roles of or...

Projected changes in extreme waves and coastal hazards along the North Indian Ocean Coast utilizing high-resolution CMIP6 wave ensemble

Ocean surface waves are key drivers for coastal dynamics, influencing shoreline changes, sediment transport, and the structural stability of coastal infrastructures. In this study, we investigated the projected changes in wave climate with a particular focus on extreme waves and...

π-Stack-Web: A Curated Database and Similarity-Guided Platform for Supramolecular Stack Generation

Abstract The generation of stable one-dimensional (1D) supramolecular assemblies is computationally demanding because identifying low-energy stacking configurations requires exploration of complex configurational spaces and highly multimodal energy landscapes. Moreover, even when...

Political connection, audit quality, and tax avoidance

Abstract Crony capitalism and business‐politics nexus have been the focus of academic research and policy‐making in recent decades, particularly in developing countries where regulatory frameworks are evolving. This study investigates the relationship between political connection...

A task-adapted structurally reparameterized diverse-branch YOLO network for mulberry leaf disease detection

Mulberry leaf diseases reduce leaf yield and quality, with direct consequences for sericulture. Detecting symptoms in field imagery is challenging because lesions are often small and visually similar across disease types. In this study, a task-adapted YOLOv10-based detector is pr...

Metal-coordinated water-assisted enhanced proton conductivity of robust Ni(II)-based 3D/2D metal-organic frameworks

MOFs are considered as frontline support materials for obtaining high proton conduction under humid conditions. This study deals with a 3D and a 2D single-crystal Ni-MOFs. The open-network 3D Ni-MOF (Ni-NDC-BPYH), constructed from 2,6-napthalenedicarboxylic acid (2,6-NDC) and 1,2...

Assessment of mechanical damage in canola using X-ray radiography and deep learning

Mechanical damage during post-harvest handling and processing can drastically impair the quality, germination potential, and market value of canola ( Brassica napus L.) seeds. Traditional visual inspection methods are subjective and limited to detecting external defects, often mi...

Synoptic and large‐scale drivers of extreme precipitation events in the Himalayas

Abstract Extreme precipitation events (EPEs) in the Western Himalayas (WH) have significant cross‐sector impacts, yet understanding of their seasonal characteristics and synoptic drivers remains inadequate. This study presents an analysis of EPEs across the full annual cycle of t...

Ultra-fast spin Hall nano-oscillator based microwave spectral analysis

Abstract Ultra-fast spectrum analysis based on rapidly tuned spintronic nano-oscillators has been under development for the last few years and has already demonstrated promising results. Here, we demonstrate an ultra-fast microwave spectrum analyzer based on a chain of five mutua...

MudraGen: Geometrically Supervised Generation of Interacting Two-Hand Mudras for preserving Indian Classical Dance Heritage

Automatic generation of hand gestures is essential for the transmission of Indian classical dance and critical for its preservation. Indian classical dance gesture datasets are inherently low-resource, and the canonical Sanskrit definitions of many mudras lack precise textual des...

A comprehensive review of guava production and regional distribution in India

Guava stands as a cornerstone of global horticulture, renowned for its adaptability, nutritional richness, and economic significance. Enhancing its productivity and nutritional quality will not only benefit millions of farmers and consumers but also reinforce guava’s vital role i...

A household level investigation into personal chauffeured automobility
