A comparative study of physically activated biochars with multiple aqueous binders for sustainable supercapacitors

Electric double-layer capacitors were fabricated using CO 2 -activated carbons derived from three biochar precursors, two industrial Finnish biochars and an in-house willow biochar, combined with water-based chitosan and styrene-butadiene rubber/carboxymethyl cellulose binders. T...

Cardiac signal monitoring using femtosecond laser inscribed FBGs in CYTOP optical fiber

In this study, fiber Bragg gratings (FBGs) were inscribed into cyclic transparent optical polymer (CYTOP) optical fibers using a femtosecond laser plane-by-plane (Pl-b-Pl) technique. A custom-designed integrated cardiac sensor was then developed, incorporating a 3D-printed struct...

Children’s health before, during, and after parental/caregiver immigration detention in the United States: findings from a cross-sectional survey

Background Parental immigration detention is a significant yet understudied stressor with potential consequences for children's well-being. We examined children's general health before, during, and after parental detention, and compared to the United States (US) pediatric populat...

Thermal-economic performance assessment of heat recovery-oriented design of integrated CCHP-H₂ system; multi-objective optimization with LCA and AdaBoost decision-making

Combined cooling, heating, power systems integrated with hydrogen production (CCHP–H₂) can simultaneously supply useful outputs while improving the utilization of fuel and recoverable thermal energy. The present project proposes a methane-fueled CCHP–H₂ configuration integrating...

Enhancing the interfacial transition zone of coal gangue aggregate mortar through the synergistic effect of red mud substitution and CO₂ mineralization during mixing

To improve the weak interfacial transition zone (ITZ) associated with coal gangue (CG) aggregates while promoting industrial solid waste valorization and carbon reduction, a synergistic modification strategy combining red mud (RM) substitution (8–24%) and in-situ CO₂ mineralizati...

Short-term thermal dynamics in single U-tube borehole heat exchangers: an unbalanced trade-off between coefficient of performance and delivered energy under variable flow rate operation

Variable-speed circulation pumps are common in ground-source heat pump (GSHP) installations, but the short-term response of borehole heat exchangers (BHEs) to variable flow is poorly resolved: line-source methods omit the in-borehole thermal capacity, and thermal-resistance-capac...

Changes in General Anesthesia Utilization Disparity among Patients with Autism Spectrum Disorder Before and After Health Insurance Coverage Expansion: A Retrospective Analysis of a Single Regional Specialized Dental Center, 2021-2025

Background: Patients in Korea with autism spectrum disorder (ASD) rely heavily on general anesthesia (GA) during dental treatments at specialized dental centers.In February 2022, the expanded National Health Insurance (NHI) coverage reduced out-ofpocket expenses for patients unde...

Optimization and controlling of the microstructure and mechanical properties of high-Nb TiAl alloy by extrusion temperature

Hot extrusion is an effective route to tailor the microstructure and mechanical performance of TiAl intermetallic alloys. In the present work, a Ti-45Al-8Nb-0.2W-0.1B alloy was multi-pass extruded at five temperatures spanning the (α + γ) two-phase region to the α single-phase re...

Explosion characteristics and flame propagation of HHO/NH3/air premixed mixtures in a closed vessel

Brown’s gas (HHO), a highly reactive carbon-free fuel, has attracted increasing attention for hydrogen-based energy applications, while ammonia (NH 3 ) is considered a promising hydrogen carrier. Understanding the explosion behavior of HHO/NH 3 /air mixtures is essential for thei...

Genetic diversity and population structure of the Asian yellow pond turtle (Mauremys mutica)

To investigate the genetic diversity and structure of farmed Asian yellow pond turtle ( Mauremys mutica ), we performed whole-genome resequencing on 180 individuals collected from eight farms spanning six regions in China. A total of 2072,663,419 single nucleotide polymorphisms (...

From curated datasets to social-media reality: In-the-wild, multimodal, and generalizable deepfake detection

Deepfake detection has advanced rapidly alongside progress in generative adversarial networks, diffusion models, neural rendering, and multimodal synthesis. However, strong performance on curated benchmark datasets does not necessarily translate into reliable performance in real-...

Radiation dose analysis in the IR-IECF device: numerical analysis with geant4 simulation and experimental measurements

This study presents a combined experimental and Geant4-based assessment of the radiation field and shielding performance of the Iranian Inertial Electrostatic Confinement fusion device (IR-IECF) operating in deuterium–deuterium (D–D) mode and producing 2.45 MeV neutrons. A detail...

Thermal plume intensification and double-diffusive transport in sawtooth-finned non-Newtonian enclosures with dual-ANN prediction

Advanced thermal engineering increasingly demands compact geometries that intensify heat and mass transport for energy storage, electronic cooling, and high-performance heat exchangers. This study introduces a centrally heated and concentrated triangular sawtooth fin within a non...

How do multidimensional land use conflicts shape rural multifunctionality? An empirical study of the Yangtze River Delta from a conflict–coordination perspective

In the context of urban–rural integration, how multidimensional land use conflict (LUC) differentially shapes rural multifunctionality is a key question for sustainable rural development. Existing studies, however, have largely treated the two independently, with limited systemat...
