GrIT: Group Informed Transformer for Sequential Recommendation

Sequential recommender systems aim to predict a user's future interests by extracting temporal patterns from their behavioral history. Existing approaches typically employ transformer-based architectures to process long sequences of user interactions, capturing preference shifts...

Resolving Erdős–Ulam Monochromatic Union-Closed Family Conjectures

We prove both Erdős–Ulam conjectures on monochromatic union-closed families, which are the two specific questions of Erdős Problem 1183. Every two-colouring of the subsets of a finite set contains a monochromatic union-closed family whose size grows faster than any fixed power of...

Reliability Analysis for Nadarajah–Haghighi Distribution Under Block Progressive Type‐II Censoring With an Application to Aircraft System Failure

ABSTRACT This article discusses estimations of reliability performance characteristics under block progressive Type‐II censoring when life tests are performed on different test facility. Different estimates are produced using classical and Bayesian frameworks, respectively, where...

Internal differentiation and caste identity: creamy layer, sub-categorisation, and the politics of equality in India

Affirmative action in India has entered a new constitutional phase in which debates extend beyond access to reservations to the equitable distribution of benefits within constitutionally protected groups. This paper examines internal differentiation within Scheduled Caste (SC) re...

A standardised auditing framework of economic, environmental, and social impact of utility-scale solar farms

The rapid worldwide deployment of utility-scale solar photovoltaic (PV) systems highlights the need for an integrated concept to evaluate their multidimensional sustainability performance. This study introduces a novel auditing protocol that combines economic, environmental, and...

Digital phenotyping and precision monitoring of honeybee colonies: emerging role of IoT and machine learning for predictive analysis

Abstract Predictive and observational monitoring of hives is essential for ensuring colony health, optimising pollination, and enhancing apicultural productivity. Traditional methods of hive monitoring, reliant on manual observation, are increasingly inadequate in addressing the...

Interpretable machine learning reveals contrasting drivers of streamflow droughts in regulated and natural river systems

This study investigates the spatial, temporal, and process-based dynamics of streamflow droughts across the Godavari River basin using daily discharge records from multiple gauging stations. A multivariate framework integrating drought duration, intensity, and deficit was employe...

Comprehensive review of CO 2 utilization: Transforming carbon into fuels, chemicals and materials for a sustainable future

Abstract Carbon dioxide (CO 2 ) utilization has emerged as a promising pathway to convert a major greenhouse gas into value‐added products, offering both environmental and economic benefits. While CO 2 to fuel, CO 2 to chemical, and CO 2 to material conversion routes have each be...

Affirmative Action in Education: A Systematic and Comparative Review of Policy, Equity and Outcomes

This study synthesizes scholarship on affirmative action in education from 2015 to 2025, drawing on 49 sources across the social sciences and allied fields. Using a PRISMA-guided systematic review of the literature, the article explores the conceptual framings that distinguish eq...

AMI-Assisted High-Capacity DWDM Optical Transmission with MIMO-OFDM for Future Networks

Line coding plays a critical role in determining the performance and reliability of digital communication systems. This paper proposes a novel high-speed optical transmission method that employs Alternate Mark Inversion (AMI) line coding in a DWDM system integrated with an OFDM m...

Context-aware image captioning using cosine transformer attention and optimal vision transformer with improved walrus optimization algorithm

Abstract Automatic image captioning aims to acquire the learning of the correlation between the visual and the linguistic cognitive domain through the generation of descriptive captions with respect to input images. But it is affected by the semantic distance between image featur...

Hierarchical federated edge learning with criticality-aware aggregation for privacy-preserving fetal health classification
