Low-velocity impact performance of aluminum honeycomb sandwich structures with composite face sheets

Abstract In this study, AL 3003 aluminum honeycomb cores with heights of 10 mm and 15 mm, which have been widely used in the automotive, aerospace, and defense industries in recent years, were employed. As face sheet materials, glass/epoxy, carbon/epoxy, and Kevlar (aramid)/epoxy...

Alaska North Slope HYDRATE 02 Geo Data Well (GDW) Downhole Logging, Pressure Coring, and Completion Operations and Data

Abstract The “Collaborative Gas Hydrate R&D Project in Alaska,” led by the Japan Organization for Metals and Energy Security (JOGMEC), the U.S. Department of Energy (DOE), and the U.S. Geological Survey, aims to examine and assess gas hydrate reservoir systems, their production b...

Uric Acid-to-High-Density Lipoprotein Cholesterol Ratio and Coronary Slow Flow: An Integrative Marker of Microvascular Dysfunction

BACKGROUND: Coronary slow flow (CSF) is an angiographic finding characterized by delayed distal vessel opacification despite normal epicardial coronary arteries. Its pathophysiology is multifactorial and involves microvascular dysfunction, endothelial impairment, and chronic infl...

Improved Artificial Protozoa Optimizer-Based PI Control for Temperature and Power Regulation of PCM Thermal Energy Storage

Phase-change material (PCM) thermal energy storage requires effective discharge regulation because the available stored energy and resulting thermal output vary continuously during operation. This study develops an Improved Artificial Protozoa Optimizer (IAPO) for proportional–in...

Taguchi-based analysis of WEDM performance of cryogenically treated and untreated Inconel 718: Surface roughness, kerf width, and material removal rate

This study investigates how deep cryogenic treated (DCT) affects the machining characteristics and surface morphology of Inconel 718 during wire electrical discharge machining (WEDM). Surface roughness (R a , R q , and R z ), kerf width (KW), and material removal rate (MRR) were...

Hybrid SIO2/AL2O3 Filler Reinforcement in Glass Fiber/Epoxy Composites: Flexural and Tensile Behavior with Physics-Informed Neural Network Validation

Glass fiber-reinforced polymer (GFRP) composites are widely used in structural applications, yet the inherent brittleness of the epoxy matrix limits their mechanical performance. While SiO2 and Al2O3 have individually been shown to improve polymer composite properties, the synerg...

Alaska North Slope HYDRATE 02 Geo Data Well Multicomponent Inversion and NMR Log and Core Analysis of the B1 Sand Gas Hydrate Reservoir

Abstract The Collaborative Gas Hydrate R&D Project in Alaska, a joint initiative by the Japan Organization for Metals and Energy Security, the U.S. Department of Energy, and the U.S. Geological Survey, aims to advance understanding of gas hydrate reservoir systems and their produ...

Hydrate-Based Carbon Dioxide Sequestration in the Black Sea: Implications for Turkiye’s Exclusive Economic Zone

Abstract This study evaluates the potential for hydrate-based carbon dioxide (CO2) sequestration within Türkiye’s Exclusive Economic Zone (EEZ) in the Black Sea by mapping the CO2 Hydrate Stability Zone (CHSZ) and estimating storage capacities under different pore-water salinity...

Classification of mandibular impacted third molar teeth on panoramic radiographs using deep learning algorithms

This study aimed to evaluate the image-based technical performance of deep learning-based models in classifying impacted mandibular third molars on panoramic radiographs. Accurate identification of angular impaction patterns is essential for treatment planning, yet manual interpr...

Effect of welding parameters on tensile and impact strength of dissimilar Hardox 450–St 52 steel joints

Abstract This study investigates the influence of welding parameters and joint configuration on the mechanical efficiency and microstructural evolution of dissimilar Hardox 450–St 52 steel joints. These materials are commonly used together in excavator and backhoe loader buckets...
