Effects of keiser-assisted Nordic hamstring curl training on hamstring flexibility, mechanical properties, and pitching performance in high school baseball pitchers

[Purpose] This study aimed to investigate the effects of 10-week Keiser-assisted Nordic hamstring curl (NHC) training on the mechanical properties, muscle strength, and flexibility of the hamstrings, as well as shoulder range of motion (ROM) and pitching performance in high schoo...

Dual-Layer Microencapsulated Phase Change Material Composite with Enthalpy-Active Shell for Thermal Absorption and Directional Heat Management

Abstract Localized heat accumulation in electronic devices degrades performance, safety, and cycle life. Phase change materials (PCMs) have been widely investigated for passive thermal regulation; however, conventional core–shell encapsulated PCMs often exhibit limited effective...

Endpoint genotyping of A2063G and A2064G mutations in Mycoplasma pneumoniae

Abstract Macrolide resistance in Mycoplasma pneumoniae is primarily associated with point mutations in domain V of the 23S rRNA gene, most commonly A2063G and A2064G. Rapid detection of these mutations is important for appropriate antimicrobial therapy. In this study, we develope...

Low-Temperature Plasma-Induced Oxygen-Vacancy Engineering Enables Orthorhombic-Phase Stabilization in Hf0.5Zr0.5O2 for 2D FeFETs toward Monolithic 3D Integration

Abstract The rapid growth in artificial intelligence and large-scale data processing has driven the urgent demand for energy-efficient electronic devices. Ferroelectric materials, especially hafnium zirconium oxide (Hf0.5Zr0.5O2, HZO), have emerged as promising candidates due to...

Physics‐Informed Agent‐Analytics Framework With Causal Validation for Crease Prediction in Multilayer Flexible Cover Stacks

ABSTRACT We propose an agent‐analytics framework for data‐driven crease mitigation in multilayer flexible cover stacks, where an LLM‐assisted workflow supports a human domain expert in formalizing engineering hypotheses into mechanics‐grounded descriptors and in organizing ensemb...

Depression as a Risk of Lung Cancer in Women: a Nationwide Cohort Study

BACKGROUND: Lung cancer is a leading contributor to global cancer incidence and mortality. While depression has been linked to adverse health behaviors, particularly tobacco smoking, that may elevate cancer risk, the direct relationship between depression and lung cancer remains...

Spatial nonparametric Bayesian Poisson hurdle model for analyzing zero-inflated tick data

Abstract Severe fever with thrombocytopenia syndrome, an infectious tick-borne disease, has been increasingly reported in South Korea. Understanding the epidemiology of its vectors will help predict the spatio-seasonal abundance of ticks and manage future health risks related to...

Dispersion-Contrasting Dual-Layer Metalens for Hybrid Chromatic-Aberration Correction in the Visible

Abstract Metalenses offer a pathway toward flat, wafer-level optics, but their translation to mobile imaging has been hindered by the difficulty of achieving broadband performance at millimeter-scale apertures. Here we report a visible metalens that imparts a wavelength-invariant...
