Wind shear severity regimes and multi-step forecasting at Hong Kong International Airport: evidence from the central runway 07C/25C

Wind shear is a critical meteorological hazard in aviation, especially during takeoff and landing, where rapid changes in wind speed and direction can affect lift and airspeed, compromise aircraft performance, and threaten safety. Existing studies predominantly focus on single-ho...

AI dependency and its relationships with anxiety, quality of life, and digital stress

Abstract Background The integration of artificial intelligence (AI) into higher education has accelerated, yet little is known about the psychological mechanisms underlying students’ reliance on AI. This study conceptualizes AI dependency as a complex cognitive–motivational const...

Nurses’ Perceptions and Behaviors Regarding Climate Change and Health: A Correlational Study Aligned With Saudi Vision 2030

ABSTRACT Climate change is an escalating threat to population health, placing increasing pressure on healthcare systems. Nurses play a pivotal role in delivering climate‐resilient healthcare; however, evidence regarding their perceptions and climate‐related health behaviors in Sa...

Smartphone based clinical decision support system for early detection of neonatal jaundice using artificial intelligence with temporal convolutional network

Abstract Physiological jaundice is present in the initial week of life in neonates owing to the rise in level of bilirubin thereby resulting in yellowish coloring of sclera and skin. Severe jaundice and lethal bilirubin levels may result from brain damage as bilirubin is located...

Reinforcement Learning‐Based Adaptive Optimal Containment Control for Constrained Nonlinear Multiagent Systems

ABSTRACT This paper proposes an adaptive optimal containment control method for nonlinear strict‐feedback multiagent systems with state constraints. First, a neural network‐based reinforcement learning algorithm is developed within an optimized backstepping framework. Unlike the...

AI-Based Optimization for Biofuel Production: Strategies for Utilizing Degraded Land for Climate Change Mitigation, Green Finance Mobilization, and Achieving United Nations Sustainable Development Goals

Global land degradation affects approximately 2 billion hectares, threatening food security, biodiversity, and climate stability while undermining the United Nations Sustainable Development Goals (SDGs). The concurrent urgency to decarbonize the energy system and mobilize green f...

Shear bond strength of ceramic orthodontic brackets to bulk-fill, packable, and flowable composite restorations under different thermal aging protocol of the substrate: an in vitro study

Long term success of orthodontic treatment depends on the bond strength of orthodontic brackets with tooth and/or restorative materials. This in vitro investigation aimed to assess and compare the shear bond strength (SBS) of ceramic orthodontic brackets bonded to bulk-fill, pack...

Metabolic Signatures Associated with COVID-19 Vaccination in Serum from Healthy Individuals

Background: COVID-19 vaccines have proven effective in reducing severe disease and mortality from SARS CoV-2 infection. The underlying molecular mechanisms and alterations in the human serum metabolome influencing the effectiveness and development of immunity remain unclear. Meth...

Explainable multi-backbone deep feature fusion based wheelchair detection with disability-aware accessibility monitoring in smart urban environments

BACKGROUND: Reliable identification of wheelchair users in public environments is an important enabling technology for assistive systems that aids independent mobility, accessibility monitoring, and inclusive public infrastructure. Accurate automated recognition could assist reha...

Secure network forensic investigation framework with elliptic curve cryptography-based encryption and enhanced message digest integrity verification

Forensic evidence can be easily altered or disclosed to those who are not authorized, which reduces the evidence integrity, reliability, and admissibility in cyber forensic investigation. Current forensic approaches are mostly concerned with evidence collection and analysis, and...

Effectiveness of plasma atherogenic index as a predictor of cardiovascular risk in patients with metabolic syndrome and related cardiometabolic conditions: a systematic review.

Metabolic syndrome (MetS) and cardiovascular-kidney-metabolic syndrome represent escalating global health challenges characterized by complex lipid derangements. While traditional lipid panels are standard, the atherogenic index of plasma (AIP) has emerged as a potentially superi...

Laparoscopic versus open appendectomy for appendicitis in children: a systematic review and meta-analysis

Acute appendicitis is among the most common pediatric surgical emergencies worldwide. Laparoscopic appendectomy (LA) has gained wide acceptance in recent years ; however, its superiority over the traditional open appendectomy (OA) is still a topic of debate, particularly regardin...

Socio-economic vulnerability and effective institutions for adaptation to compounding climate hazards in Africa
