We study a global transonic solution for a relativistic, magnetized, viscous advective accretion flow around a rotating black hole, incorporating the effects of mass and angular momentum loss through winds. Our model con...

Abstract Prior observational uncertainties have hindered the clear understanding of the link between tropospheric Lamb waves and ionospheric disturbances. In this study, we precisely extracted ionospheric Lamb waves orig...

Abstract The conversion of solar radiation into thermal energy has gained increasing attention due to the growing demand for renewable sources of heat and electricity. Nanofluids, owing to their enhanced heat transfer ca...

Plasmonic nanoantennas have the ability to confine and enhance incident electromagnetic fields into very sub-wavelength volumes, while at the same time efficiently radiating energy to the far-field. These properties have...

The main objectives of this study are to enhance the power extraction of photovoltaic (PV) systems under rapidly changing ecological circumstances using Maximum Power Point Tracking (MPPT) and to improve the power qualit...

Abstract Objective Photon-counting CT (PCCT) combines improved dose efficiency with spectral imaging, enabling dynamic functional imaging at chest CT dose levels. Dual energy CT typically uses perfused blood volume (PBV)...

Currently, subsea mining is primarily limited to sea sand extraction and deep-sea mining that focus mainly on mining activities at the seabed surface. These conventional methods not only pose significant environmental ri...

Goji berry polysaccharides have physiological functions such as antioxidant, anti-tumor, liver protection, blood sugar lowering, and immune regulation. They have good therapeutic effects on preventing and treating some c...

Abstract Background Timely and accurate pregnancy detection in the dairy animals is essential for minimizing calving intervals to accelerate reproductive turnover and increase milk production from livestock farming. Urin...

Under adverse weather conditions, ice accumulation and strong winds cause low-frequency and high-amplitude swaying of transmission lines, increasing the risk of wire fatigue, hardware damage, and tower collapse, posing a...

Abstract Due to the complexity of substation systems and the diversity of data sources, potential inaccuracies or inconsistencies in data may compromise the accuracy of intelligent detection. To address this issue, an in...

INTRODUCTION: Accurate power quality disturbances (PQDs) classification is critical for maintaining grid stability and reliability in modern power systems. However, existing deep learning methods predominantly rely on si...

Fil: Lacabana, Miguel. Universidad Nacional de Quilmes; Argentina. Las masivas intervenciones antrópicas con sus consecuencias de incremento de gases efecto invernadero (GEI) y cambio climático que afectan a las poblac...

"La constante demanda energética mundial y las nuevas políticas económicas han impulsado a la industria petrolera a lograr grandes avances en lo referente a técnicas de extracción de hidrocarburos y ha llevado a té...
