Hashchain-based Authentication Framework Against Blended Attacks in Constrained IoT Networks

Many Internet of Things (IoT) deployments rely on multi-hop routing protocols designed for low-power and resource-constrained devices. These protocols are susceptible to routing attacks that degrade network reliability, compromise data integrity, and disrupt system operation. Exi...

β-carotene enhances drought tolerance in fenugreek by modulating antioxidant defense and redox homeostasis

Drought stress is one of the main abiotic factors that modulates the morphology and physiology of crops. This study investigated the effect of foliar application of β-carotene on the growth, physiological, and biochemical responses of fenugreek (Trigonella foenum-graecum L.) unde...

Norepinephrine Versus Vasopressin as First-Line Vasopressor Therapy in Septic Shock: Implications for Patients Presenting to the Emergency Department

Background: Septic shock requires rapid restoration of perfusion with infection treatment. Norepinephrine is the recommended initial vasopressor, while vasopressin offers an alternative mechanism of vascular support. This review examines comparative clinical outcomes and their re...

Job satisfaction among Saudi and Non-Saudi critical care and emergency nurses: associations with psychological distress, turnover intention, and perceived retention strategies

Critical care and emergency nurses work in complex and demanding environments that may affect their occupational well-being, psychological health, and job satisfaction. Although previous studies have examined nurse retention challenges, limited evidence exists regarding factors a...

Integrative Multi-Omics Analysis Reveals Host Regulatory and Immune Networks with Inferred Dysbiosis Relevance in Colorectal Cancer

Background: Colorectal cancer (CRC) remains one of the leading causes of cancer-related mortality worldwide. Increasing evidence suggests that intestinal microbial dysbiosis contributes to colorectal tumorigenesis by reshaping host molecular signaling and the tumor immune microen...

Carbon mitigation governance strategies in Morocco, China, and Norway

This study examines the gap between the mitigation objectives promoted under the Paris Agreement and their implementation within contrasting national contexts. Using Morocco, China, and Norway as strategically selected cross-continental case studies, the paper evaluates how share...

Comparative efficacy and safety of intra-articular versus intravenous tranexamic acid in primary total knee arthroplasty: a systematic review and meta-analysis

Total knee arthroplasty (TKA) is frequently associated with considerable perioperative and postoperative blood loss, making tranexamic acid (TXA) a key component of modern blood-sparing protocols. Although both intravenous (IV) and intra-articular (IA) routes are widely used, the...

Machine Learning for Autism Spectrum Disorder Prediction: A Review of Data Augmentation and Feature Selection Techniques

ABSTRACT Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by persistent difficulties in social communication, social interaction, and repetitive behaviors. Early and accurate diagnosis is essential but is often hindered by subjective clinical...

A secure multilayer audio encryption scheme based on chain ring algebraic S-boxes, Rössler diffusion, and 4D hyperchaotic permutation

Abstract The secure transmission of digital audio requires encryption techniques that can protect audio information against different types of cryptanalytic attacks. Existing chaos-based audio encryption methods commonly use conventional $$\:GF\left({2}^{8}\right)$$ -based substi...

EdgeTwin-DRL: Real-Time Counter-UAS Detection and Response Optimization Using Edge-Assisted Digital Twins and Multi-Agent Deep Reinforcement Learning

The time available for a counter-drone system to detect an unauthorized aircraft and determine an appropriate response can be limited. Although cloud processing remains useful for storage and offline analysis, communication delays may constrain its use in time-critical decision l...

Maternal Psychological Distress and Parent-Reported Child Behavioural and Emotional Outcomes Among Mothers of Children with Autism Spectrum Disorder: A Cross-Sectional Study

Background: Mothers of children with autism spectrum disorder (ASD) face numerous challenges in meeting their children’s needs. This study aimed to assess parent-reported child behavioural and emotional outcomes and the levels of anxiety, depression, and stress among mothers of c...

Determinants of self-esteem among children in Jordan

Self-esteem is an important factor affecting personality development. School-aged children can have lower self-esteem levels compared to people of other age groups and it can be influenced by several factors which vary across cultures. This study aimed to assess self-esteem and e...

A layer-aware graph attention and patch transformer framework for multi-class IIoT attack classification

The proliferation of IIoT devices has dramatically expanded the attack surface of critical infrastructure. IIoT systems span multiple communicating tiers from physical sensors to cloud back-ends, attackers increasingly exploit inter-tier boundaries in ways that single-layer detec...

Integrated optimization for least-cost, low-emission electricity pathways: Evidence from Saudi Arabia

This paper analyses least-cost, low-emission electricity pathways for Saudi Arabia over 2018–2040. Using the LEAP modelling framework, four supply pathways are evaluated under a common electricity demand trajectory reaching 640.2 TWh by 2040, requiring approximately 707.4 TWh of...

Quad port MIMO antenna design for WLAN and N78 application using regression machine learning validation
