Board gender diversity and renewable energy consumption: evidence from G20 countries

Purpose The purpose of the study is to examine the impact of board gender diversity (BGD) on renewable energy consumption in firms across G20 countries. Design/methodology/approach Firm-level data are collected from the LSEG database, and country-level data from the World Bank, W...

From Noise to Knowledge: Distill Social Media Opinions on Rumor Detection Exploiting LLMs

The majority of social media research relies on datasets gathered from social media websites such as Reddit and Twitter. However, their intrinsic high noisy content reduces the performance of data-driven models. This restriction of noisy data has made data preparation techniques...

Nitrogen-Incorporated Reduced Graphene Oxides as ElectrodeMaterials for Tunable Electrochemical Applications

Abstract Because of high defect density and good electrical conductance, nitrogen-incorporated reduced graphene oxides (NrGOs) are highly promising materials for energy storage, energy conversion, and electrochemical applications. Surface area modifications and controllable elect...

Quartz Optimizer: Robust Gradient Shaping and Bounded Adaptive Steps for Stable Deep Learning Training

Optimization plays a critical role in training deep neural networks, directly impacting convergence speed, model generalization, and stability. While existing methods such as stochastic gradient descent (SGD) and adaptive optimizers like Adam and AdamW have achieved significant s...

ControllingSpin-Vibrational Coupling and Spin Relaxationin Cu(II) Molecular Spin Qubits via Ligand Rigidity

Abstract A clear understanding of spin relaxation is central to the design and development of molecular spin qubits. A detailed computational study of spin-vibrational coupling and spin–lattice relaxation is presented here for a series of Cu(II) complexes with varying ligand rigi...

Decoding the MicroscopicEffects of BiocompatibleIonic Liquids on Model Phospholipid Membrane

Abstract Ionic liquids (ILs) are increasingly explored in pharmaceutical and therapeutic applications because of their roles in drug delivery and biomolecular stabilization. As cell membranes serve as the primary protective barrier of the cellular environment, decoding the effect...

Experimental investigation on the shear strength, consolidation and permeability characteristics of cross-linked biopolymer-stabilized soils

This study investigates the influence of guar gum (G), xanthan gum (X), and their cross-linked blend on the shear strength and consolidation characteristics of soils with contrasting plasticity and mineralogical characteristics. Direct shear, one-dimensional consolidation, consta...

Updated comprehensive probabilistic seismic hazard analysis of the Andaman-Nicobar and Sumatra regions

The Andaman-Sumatra subduction zone is among the most seismically active regions on Earth and has generated several great earthquakes (M w ≥ 8.0) in recent decades. This study presents an updated probabilistic seismic hazard assessment (PSHA) for the Andaman-Nicobar and Sumatra r...

Probabilistic seismic hazard and historical scenario-based assessment of liquefaction potential in the Bengal Basin for liquefaction mitigation strategies

Soil liquefaction and ensuing ground failure significantly contribute to structural damage in loose, non-cohesive, and water-saturated alluvial regions during moderate-to-great earthquakes. The Bengal Basin, situated on the Ganga-Brahmaputra-Meghna Deltaic deposits, exhibits a su...

Strength and environmental assessment of fly ash-slag-stabilised kaolin for road sub-base

The stabilisation of weak soils, such as kaolin, is essential for improving their engineering properties for geotechnical applications. This study investigates kaolin stabilisation using fly ash (FA) and ground granulated blast furnace slag with 12 mixes at 10%, 20%, and 30%. Lab...

Threshold Encrypted Search System from Function Secret Sharing

We propose a novel multi-server threshold oblivious retrieval system (ThORY). Our construction extends DORY (a two-server non-threshold oblivious retrieval system proposed in USENIX OSDI 2020) to support arbitrary threshold access structures. The technical centrepiece of ThORY is...
