Magnetic granular matter: A review of phenomena and modeling approaches

Abstract Magnetic granular matter extends classical granular physics through the introduction of tunable, long-range dipolar interactions. These interactions give rise to a wide range of collective phenomena, including field-aligned chain formation, enhanced cohesion, anisotropic...

Interfacial synergy in NiO-MnO2-g-C3N4 ternary heterostructure nanostructure for enhanced electrocatalytic water splitting

Developing affordable, highly stable, and efficient bifunctional electrocatalysts for overall water splitting and hydrogen production is essential for advancing clean and sustainable energy technologies. In this study, a ternary heterostructure nanocomposite consisting of NiO, Mn...

Circular Economy Readiness and Sustainable Value Creation: A Moderated Mediation Model of Green Intellectual Capital and Environmental Uncertainty

ABSTRACT This paper examines the relationship between circular economy readiness (CER) and sustainable value creation (SVC), as well as the mediation between CER‐SVC by green intellectual capital (GIC) and the moderation between CER‐SVC by environmental uncertainty (EU) in the co...

Interfacial-coupling-driven 2D Ni(OH)2/SnO2 hybrid heterostructures for carbon-free, durable supercapacitor electrodes

Low-cost, carbon-free electrodes that stay stable over long cycling are hard to make without conductive scaffolds such as graphene or carbon nanotubes. We report 2D Ni(OH) 2 /SnO 2 hybrid nanostructures prepared by a single-step hydrothermal route, in which ultrathin β-Ni(OH) 2 n...

Exact Stability Atlases and a Memoryless-Surrogate Failure Theorem for a Caputo Allee Predator-Prey Model

We study a strong-Allee predator–prey system with Holling type-II predation under a commensurate Caputo derivative of order α∈(0,1]. The coexistence equilibrium is given in closed form, and its local fractional stability reduces to the trace and determinant of the Jacobian, both...

Epidemiological trends and pertussis-related mortality in Jigawa State, Northwest Nigeria: evidence from five years of case-based surveillance

To describe five-year epidemiological trends of pertussis in Jigawa State, northwest Nigeria, using case-based surveillance data. A retrospective descriptive cross-sectional analysis was conducted on 768 pertussis cases reported through the Integrated Disease Surveillance and Res...

Lightweight online offline authenticated encryption for secure UAV systems

Abstract Unmanned aerial vehicles (UAVs) are rapidly being used for surveillance, environmental monitoring, disaster response, and intelligent transportation systems. However, protecting their connection remains a significant issue due to open wireless channels, severe energy lim...

Closed-Form Solutions and Stability of Delayed Discrete Matrix Equations with Second-Order Differences and Multiple Delays

This paper presents a new technique for finding explicit solutions to multi-delay linear discrete matrix equations. The method suggested here does not need the coefficient matrices to commute with each other or the coefficient matrices and the nonhomogeneous term. The fundamental...

Dynamic Analysis and Optimal Control Strategy for the Impact of Stem Cell Therapy on Type 1 Diabetes

Type 1 diabetes (T1D) is a chronic autoimmune disease in which autoreactive effector T cells destroy insulin-producing pancreatic β-cells, leading to impaired insulin production and long-term metabolic complications. This study develops a mathematical model of the interactions am...

Lead-free Cs2MH6 (M = Ge, Sn) vacancy-ordered double perovskites for optoelectronic applications: a first-principles study

Abstract Lead-free vacancy-ordered double perovskite hydrides are gaining attention as environmentally friendly materials for next-generation optoelectronic applications. In this work, first-principles density functional theory (DFT) calculations are employed to systematically in...

Effectiveness of gabapentinoids for postoperative pain management and opioid reduction after lumbar spine surgery: a systematic review and meta-analysis

Background Lumbar spine surgery is commonly associated with moderate to severe postoperative pain, often requiring opioid analgesics. Gabapentinoids are widely incorporated into multimodal analgesic regimens; however, their effectiveness in this setting remains uncertain. Methods...

Nocturnal Surface Urban Heat Island Dynamics in a Semi-Arid Mediterranean City: Evidence from Damascus

Although nocturnal surface urban heat islands, which impede physiological recovery during rest, have been characterized in many cities worldwide, Syria’s capital, Damascus, situated in the Eastern Mediterranean region, remains without a quantitative, multi-time assessment of its...

Tracing the Roots of Inquiry: A Historical Review of Nursing Research Through Professionalisation Theory

ABSTRACT Nursing research has developed unevenly across history, shaped by shifting institutional structures, professional aspirations and societal demands. Yet existing historical reviews have largely adopted descriptive approaches, while few have applied an explicit theoretical...

A Feature‐Enhanced Artificial Neural Network‐Assisted Adaptive Truncated EWMA Control Chart for Robust Monitoring of Contaminated Processes

ABSTRACT The use of conventional memory‐type control charts can be significantly hindered by the presence of outliers and contaminated observations, as these can lead to excessive false alarms and be difficult to detect true process shifts. To tackle the aforementioned problems,...

Leakage-Aware Multi-Representation EEG Fusion with Confidence-Gated Learnable MLP for Robust Epileptic Seizure Detection

Automated epileptic seizure detection from Electroencephalogram (EEG) signals remains challenging due to the non-stationary nature of EEG activity, strong inter-patient variability, and the tendency of window-based evaluation protocols to produce overly optimistic results when te...

Ocular complications following facial dermal filler injections: a systematic review and proportion meta-analysis of visual and neurologic outcomes

Background Facial dermal fillers are widely used for aesthetic procedures but can rarely cause severe ocular and cerebral vascular complications. This systematic review and meta-analysis evaluated the spectrum of ocular complications and quantified permanent vision loss and brain...

Teacher accountability and educational reform: Exploring Saudi EFL teachers’ well-being, professional practice and identity

Saudi Arabia's Vision 2030 reform agenda emphasises teacher accountability to improve education and provide students with future skills. Despite its policy significance, there is a lack of research on how English as a Foreign Language (EFL) teachers in Saudi Arabia perceive the a...

Assessment of combustion behavior and catalytic converter deposits in a CI engine operated with MWCNT-enriched pongamia biodiesel: experimental study

Abstract Although biodiesel seems to be a promising alternative fuel for compression ignition (CI) engines, its use can cause deposit formation on the catalytic converter and impact engine durability. The effects of 30 ppm multi-walled carbon nanotube (MWCNT) dispersed Pongamia b...

Combined Effects of Physiotherapy and Vitamin D Supplementation on Pain, Disability, and IL-6 Expression in Chronic Low Back Pain: A Randomized Controlled Trial
