A hybrid framework with uncertainty-aware cooperative fusion for robust spectrum sensing in beyond 5G cognitive radio networks

This paper presents a hybrid Gated Recurrent Unit–Long Short-Term Memory–Convolutional Neural Network (GRU–LSTM–CNN) deep learning framework designed to enhance Cooperative Spectrum Sensing (CSS) in Cognitive Radio (CR) networks. The proposed architecture combines Convolutional N...

High-Isolation Super-Wideband MIMO Antenna Based on Elliptical-Ring Geometry for Next-Generation Wireless Applications

In this work, a compact elliptical-shaped multiple-input multiple-output (MIMO) super-wideband antenna with port isolation greater than 17 dB is suggested for use in future wireless communication systems. The simulated outputs indicate a super-wide band from 2 to 30 GHz, with a p...

Sociodemographic Predictors of Neurological Outcomes and Quality of Life in Acute Stroke Patients: A Hospital-based Prospective Study from South India

Abstract Introduction: Stroke remains a major cause of death, disability, and reduced quality of life worldwide, with a disproportionate burden in low- and middle-income countries. In India, inequalities in income, occupation, education, and access to preventive care may influenc...

Development of a Deep Learning Model for Audio Question Answering (AQA)

This paper presents a high-efficiency multimodal framework designed for Audio Question Answering (AQA). To overcome standard CPU and disk I/O bottlenecks, the architecture implements a zero-I/O data pipeline that pre-processes and caches 10,686 samples directly into the 48 GB VRA...

Genome-wide association analysis of endometriosis in Indian women supports shared genetic susceptibility and suggestive population specific signals

Endometriosis is an estrogen-dependent, chronic gynaecological disorder affecting approximately 10% of women of reproductive age and is associated with pelvic pain, infertility, and reduced quality of life. Genetic studies indicate substantial heritability, yet genome-wide associ...

Machine learning-based optimization, characterization and CI engine assessment of biodiesel synthesised from waste soybean cooking oil

Abstract Waste cooking oil as a feedstock for biodiesel production is a sustainable choice which resolves the environmental concerns related to its disposal. The present paper focusses on biodiesel production from waste soyabean oil via transesterification using ethanol and potas...

Traditional agroecological calendar, phenology, and biotic indicators among the Lepchas of Sikkim, Eastern Himalaya

Traditional ecological knowledge plays a crucial role in understanding ecological processes, seasonal forecasting, and sustainable agroecosystem management among indigenous communities.The present study documents and analyzes the traditional agroecological calendar and biotic eco...
