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...

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...

The Individualization of Joint Tort Liability and Article 3 of the Trade Union and Labor Relations Adjustment Act: Implications for Korean Civil Law of Liability Apportionment and the Reduction of Damages

위법한 쟁의행위로 인한 손해배상책임에서 공동가해자별 책임을 어떻게 조정할 것인지는 공동불법행위의 부진정연대책임 구조와 노동조합 활동의 특수성이 교차하는 문제이다. 공동불법행위책임은 피해자에 대한 외부관계에서는 아직 전보되지 않은 손해에 관한 공동책임을, 공동가해자 사이의 내부관...

Comparative analysis of parametric X-ray radiation from diamond powders with varying particle sizes

The traditional Debye-Scherrer method for crystallite size determination faces fundamental limitations when analyzing nanosized objects due to peak broadening effects. This research explores parametric X-ray radiation (PXR) as a promising alternative approach, where radiation is...

Multimodality imaging of lithopedion in a postmenopausal woman: A case report emphasizing the diagnostic role of noncontrast computed tomography

Lithopedion is a rare sequela of unrecognized extrauterine pregnancy in which a nonviable fetus undergoes calcification and may retain for years, that occurs in approximately 0.005% of entire pregnancies and 1.5%-1.8% among abdominal ectopic pregnancies. We present a case of 62-y...
