    FDMP-Fluid Dynamics & Materials Processing, Vol.22, No.1, 2026, DOI:10.32604/fdmp.2026.076681 - 06 February 2026

    Abstract Predicting the precise impacts of climate change on extreme winds remains challenging, yet strong storms are widely expected to occur more frequently in a warming climate. Wind barriers are commonly used on bridges to reduce aerodynamic loads on trains through blocking effects. This study develops a novel wind barrier based on Tesla valves, which not only blocks incoming flow but also dissipates mechanical energy through fluid collision. To demonstrate this energy-dissipation capability, a Tesla plate is placed in a circular duct to examine its influence on pressure drop. Experimental tests and numerical simulations comparing a… More >

    CMES-Computer Modeling in Engineering & Sciences, Vol.146, No.1, 2026, DOI:10.32604/cmes.2025.074898 - 29 January 2026

    Abstract In this work, a computational modelling and analysis framework is developed to investigate the thermal buckling behavior of doubly-curved composite shells reinforced with graphene-origami (G-Ori) auxetic metamaterials. A semi-analytical formulation based on the First-Order Shear Deformation Theory (FSDT) and the principle of virtual displacements is established, and closed-form solutions are derived via Navier’s method for simply supported boundary conditions. The G-Ori metamaterial reinforcements are treated as programmable constructs whose effective thermo-mechanical properties are obtained via micromechanical homogenization and incorporated into the shell model. A comprehensive parametric study examines the influence of folding geometry, dispersion arrangement, More >

    CMES-Computer Modeling in Engineering & Sciences, Vol.146, No.1, 2026, DOI:10.32604/cmes.2025.074680 - 29 January 2026

    Abstract Fluid dynamic research on rectangular and trapezoidal fins is aimed at increasing heat transfer by means of large surfaces. The trapezoidal cavity form is compared with its thermal and flow performance, and it is revealed that trapezoidal fins tend to be more efficient, particularly when material optimization is critical. Motivated by the increasing need for sustainable energy management, this work analyses the thermal performance of inclined trapezoidal and rectangular porous fins utilising a unique hybrid nanofluid. The effectiveness of nanoparticles in a working fluid is primarily determined by their thermophysical properties; hence, optimising these properties… More >

    Sanjog Chhetri Sapkota1,2, Liborio Cavaleri3, Ajaya Khatri4, Siddhi Pandey5, Satish Paudel6, Panagiotis G. Asteris7,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.146, No.1, 2026, DOI:10.32604/cmes.2025.069691 - 29 January 2026

    Abstract Optimization is the key to obtaining efficient utilization of resources in structural design. Due to the complex nature of truss systems, this study presents a method based on metaheuristic modelling that minimises structural weight under stress and frequency constraints. Two new algorithms, the Red Kite Optimization Algorithm (ROA) and Secretary Bird Optimization Algorithm (SBOA), are utilized on five benchmark trusses with 10, 18, 37, 72, and 200-bar trusses. Both algorithms are evaluated against benchmarks in the literature. The results indicate that SBOA always reaches a lighter optimal. Designs with reducing structural weight ranging from 0.02%… More >

    Synthesis and Photoresponse of Quinary Zinc-Blende Cu3FeInSnS6 Nanoplates

    Dehui Li1,#, Yiming Guo1,#, Tao He1, Binbin Zhang1, Haixia Yu2,*, Lingkun Meng1,*

    Chalcogenide Letters, Vol.23, No.1, 2026, DOI:10.32604/cl.2026.075922 - 26 January 2026

    Abstract Quinary Cu3FeInSnS6 (CFITS) nanoplates were synthesized through a synergistic dual-cation substitution strategy using a hot-injection method, where oleylamine and 1-dodecanethiol served as coordinating ligands to guide two-dimensional growth. The nanocrystals were characterized by X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, and absorption spectroscopy. Structural analysis confirms that the CFITS nanoplates crystallize in a phase-pure cubic zinc-blende structure (space group F-43 m) without detectable secondary phases. Optical measurements reveal that the nanoplates exhibit broad and intense visible-light absorption with a direct bandgap of 1.51 ± 0.03 eV, suitable for photovoltaic applications. Under standard AM 1.5 G… More >

    Thermal Insulation Performance of Natural Fibre-Reinforced Composites—A Comprehensive Review

    Raviduth Ramful*

    Journal of Renewable Materials, Vol.14, No.1, 2026, DOI:10.32604/jrm.2025.02025-0116 - 23 January 2026

    Abstract Typically used thermal insulation materials such as foam insulation and fibreglass may pose notable health risks and environmental impacts thereby resulting in respiratory irritation and waste disposal issues, respectively. While these materials are affordable and display good thermal insulation, their unsustainable traits pertaining to an intensive manufacturing process and poor disposability are major concerns. Alternative insulation materials with enhanced sustainable characteristics are therefore being explored, and one type of material which has gained notable attention owing to its low carbon footprint and low thermal conductivity is natural fibre. Among the few review studies conducted on… More > Graphic Abstract

    Role of NETosis in the Pathogenesis of Respiratory Diseases: Molecular Mechanisms and Emerging Insights

    SEUNGIL KIM, GUN-DONG KIM*

    BIOCELL, Vol.50, No.1, 2026, DOI:10.32604/biocell.2025.073781 - 23 January 2026

    Abstract Neutrophil extracellular trap (NET) formation or NETosis is a specialized innate immune process in which neutrophils release chromatin fibers decorated with histones and antimicrobial proteins. Although pivotal for pathogen clearance, aberrant NETosis has emerged as a critical modulator of acute and chronic respiratory pathologies, including acute respiratory distress syndrome, asthma, and chronic obstructive pulmonary disease. Dysregulated NET release exacerbates airway inflammation by inducing epithelial injury, mucus hypersecretion, and the recruitment of inflammatory leukocytes, thereby accelerating tissue remodeling and functional decline. Mechanistically, NETosis is governed by peptidyl arginine deiminase 4 (PADI4)-mediated histone citrullination, NADPH oxidase-dependent reactive More >

    Melatonin as a Neuroprotective Agent in Ischemic Stroke: Mechanistic Insights Centralizing Mitochondria as a Potential Therapeutic Target

    Mayuri Shukla1, Soraya Boonmag2, Parichart Boontem1, Piyarat Govitrapong1,*

    BIOCELL, Vol.50, No.1, 2026, DOI:10.32604/biocell.2025.072557 - 23 January 2026

    Abstract Ischemic stroke is one of the major causes of long-term disability and mortality worldwide. It results from an interruption in the cerebral blood flow, triggering a cascade of detrimental events like oxidative stress, mitochondrial dysfunction, neuroinflammation, excitotoxicity, and apoptosis, causing neuronal injury and cellular death. Melatonin, a pleiotropic indoleamine produced by the pineal gland, has multifaceted neuroprotective effects on stroke pathophysiology. Interestingly, the serum melatonin levels are associated with peroxidation and antioxidant status, along with mortality score in patients with severe middle cerebral artery infarction. Melatonin exhibits strong antioxidant, anti-inflammatory, and anti-apoptotic properties and preserves More >

    HATLedger: An Approach to Hybrid Account and Transaction Partitioning for Sharded Permissioned Blockchains

    Shuai Zhao, Zhiwei Zhang*, Junkai Wang, Ye Yuan, Guoren Wang

    CMC-Computers, Materials & Continua, Vol.86, No.3, 2026, DOI:10.32604/cmc.2025.073315 - 12 January 2026

    Abstract With the development of sharded blockchains, high cross-shard rates and load imbalance have emerged as major challenges. Account partitioning based on hashing and real-time load faces the issue of high cross-shard rates. Account partitioning based on historical transaction graphs is effective in reducing cross-shard rates but suffers from load imbalance and limited adaptability to dynamic workloads. Meanwhile, because of the coupling between consensus and execution, a target shard must receive both the partitioned transactions and the partitioned accounts before initiating consensus and execution. However, we observe that transaction partitioning and subsequent consensus do not require… More >
