Same hospital, same price, different protection: out-of-pocket expenditure for emergency trauma under public insurance, private insurance and self-payment in India

Background Out-of-pocket expenditure (OOPE) finances 43.4% of total health expenditure in India, and emergency trauma—unforeseeable, unpostponable and costly—is among the sharpest tests of whether a health-financing mechanism protects households from catastrophic spending. Insure...

Unlocking catalytically active sites in FeMnS/MXene@Ni(OH)2 arrays via heterojunction strategy for highly efficient overall water splitting

Developing efficient and earth-abundant bifunctional electrocatalysts for water electrolysis remains a critical challenge due to sluggish reaction kinetics and limited structural durability. Herein, a FeMnS/Ti 3 C 2 T x @Ni(OH) 2 (NFMM) heterostructure is fabricated through the s...

First evidence of bright-red syndrome in Pacific white shrimp Penaeus vannamei broodstock from India

Abstract Objective This study aimed to isolate and characterize the putative causative agent of bright-red syndrome (BRS) in Pacific white shrimp Penaeus vannamei broodstock in India and to evaluate its pathogenic potential through controlled experimental infection. To the best o...

Comprehensive investigation of intermittent large-amplitude excursions in the memristive Hindmarsh-Rose neuron model

Abstract This study systematically investigates intermittent large-amplitude oscillations across all three state variables of the memristive Hindmarsh–Rose neuron model. The large-amplitude excursions, arising from interior crisis-induced intermittency, are first identified throu...

Energy Efficient Federated Graph Reinforcement Learning and Digital Twin Assisted Demand Response for Blockchain-Enabled Self-Healing Smart Grids

Abstract Smart grids today are highly decentralized and data-driven, with the growing incorporation of renewable energy resources, electric vehicles, distributed energy systems and intelligent edge devices. Energy efficiency, operational resilience, privacy protection and secure...

Microstructure and mechanical properties of bimetallic austenitic stainless steel 317 L/inconel 686 fabricated by wire arc additive manufacturing

This study investigated the feasibility of fabricating a bimetallic structure composed of austenitic stainless steel (SS317L) and the nickel-based superalloy Inconel 686 using Gas Metal Arc Welding (GMAW)-based Wire Arc Additive Manufacturing (WAAM). The microstructural evolution...

Digital Paradox Navigation: A Second‐Order Cybernetic Framework for Organisational Reflexivity in Digital Transformation

ABSTRACT This study develops and empirically examines the Digital Paradox Navigation (DPN) framework, which integrates second‐order cybernetics with digital transformation theory to explain how organisations manage paradoxical tensions through reflexive self‐observation. Using a...

Machine learning for mechanical property assessment and optimisation in hybrid natural fibre/epoxy composites

The development of sustainable engineering materials and rising environmental awareness has encouraged the development of research in high performance natural fibre reinforced polymer composites. This study aims to provide a comprehensive experimental and machine learning based s...
