A New Current Fingerprinting Sensing Method for Adaptive Protection of PV-Integrated Distribution Networks

Grid-following photovoltaic (PV) inverters inject fault currents whose magnitude and phase are set by the control mode active during the disturbance, so directional overcurrent relay (DOCR) settings coordinated for one inverter response can miscoordinate after a mode change. This...

DA-MC-SEP: a distance-aware multi-hop clustering and stable election protocol for heterogeneous WSNs

Abstract Wireless Sensor Networks (WSNs) consist of large numbers of sensor nodes (SNs) operating under strict energy constraints, making efficient routing protocols essential for extending network lifetime and ensuring reliable data delivery. This paper introduces a Distance-Awa...

Torque expression in directly printed and thermoformed clear aligners: a controlled in vitro biomechanical comparison of power ridge effects

Abstract Background Torque control of anterior teeth remains a major challenge in clear aligner therapy. Power ridges have been introduced to improve buccolingual root control; however, their biomechanical performance in directly printed aligners remains insufficiently investigat...

Evaluating How Artificial Intelligence Tools Influence Educational Outcomes, Usage Patterns, and User Perceptions in Research Proposal Development: A Convergent Mixed Methods Study.

Abstract Background Artificial intelligence (AI) is increasingly integrated into higher education, including medical education, particularly for research training and academic writing. Research methodology and biostatistics courses are often perceived as challenging, with student...

Carotid artery stenting utilizing self-expansion without post-stenting angioplasty in patients at high risk for reperfusion injury (a pilot study of a technical modification)

Carotid artery stenosis accounts for 15–20% of cerebrovascular ischemic strokes. Endovascular carotid artery stenting (CAS) has been recognized as an alternative treatment method for carotid artery stenosis with outcomes similar to carotid endarterectomy (CEA) [ 1 ]. One of the m...

Cluster headache care gaps among primary healthcare physicians in the Middle East, North Africa, and Türkiye: a multinational study

Cluster headache is one of the most severely disabling primary headache disorders and is frequently associated with diagnostic delay, inappropriate treatment, disability, and substantial psychosocial burden. Because primary healthcare (PHC) physicians are commonly the first point...

Characterizing optimal task latency in mobile edge computing both mathematically and metaheuristically

Abstract A large body of research has recently focused on minimizing task latency in mobile edge computing (MEC). Researchers in the field have typically posed the minimization exercise as a non-convex optimization problem and solved it either mathematically or metaheuristically,...

Improving the cryo-resistance of Egyptian buffalo semen via chlorogenic acid and rutin supplementation: molecular docking, antioxidant, and anti-apoptotic pathways

Abstract This study compared the antioxidant effects of chlorogenic acid (CGA) and rutin (RU) supplementation in freezing extenders on the cryo-resistance of buffalo spermatozoa. Over eight weeks, 56 ejaculates were collected from seven fertile buffalo ( Bubalus bubalis ) bulls....

Effect of Artemisia Annua on oxidative stress and antioxidant gene expression in Nile tilapia after chlorpyrifos toxicity

Abstract In this study, the toxic effects of chlorpyrifos (CPF) on fish antioxidant enzyme activity in serum and transcriptomic levels of oxidative stress-related genes in liver tissue and histopathology of the liver tissue of Nile tilapia were examined. Additionally, the effects...

Comparative effectiveness of 31 endodontic file systems on postoperative pain: a systematic review and network meta-analysis

Postoperative pain following root canal treatment remains a common clinical problem, with the influence of engine‑driven endodontic file systems on pain being unclear. We conducted a PROSPERO‑registered systematic review and network meta‑analysis, reported in accordance with PRIS...

Integrated geophysical and hydrogeochemical characterization of a fractured limestone aquifer in new Tuna El Gabel village, West El-Minia, Egypt

Abstract Groundwater is a vital component of water supply in arid regions, such as West El-Minia Governorate, Egypt, where water scarcity is projected to worsen, with per capita water supply expected to drop below 500 m 3 by 2025. In response, Egypt’s One and a Half Million Fedda...

GL-TGS: Guarded Learning-Based Time-Gap Supervision for Adaptive MPC in Perception-in-the-Loop Autonomous Highway Driving

Adaptive cruise control (ACC) tracks a time-gap reference that trades efficiency against spacing safety; in practice this gap is fixed offline, although the safest choice depends on the closing speed and on the reliability of the perception that supplies the lead-vehicle state. W...

Pre-monsoon hydrochemistry and multivariate analysis of deep groundwater, Sagar Island, Sundarbans

Abstract Deep Quaternary aquifers in Holocene mega-deltas are often assumed to be protected by low-permeability clay aquitards, yet they remain vulnerable to climate-driven and anthropogenic stress. This study investigated the confined aquifer system of Sagar Island, India, durin...

Effect of diode laser and hyaluronic acid on occlusion of dentinal tubules: an in-vitro study on human dentin

Abstract Background Dentin hypersensitivity (DH) is a common clinical condition characterized by short, sharp pain arising from exposed dentinal tubules. Occlusion of dentinal tubules remains a widely accepted approach for managing DH in dental practice. This in vitro study aimed...
