The Astrophysical Journal, 1974 Sizes of starspots on flare stars can be derived from the author's convection-cell hypothesis. The sizes are in fair agreement with those observed on YY Gem, CC Eri, and BY Dra by Bopp and Evans (1973). The hypothesis predicts that periodic brightness variations due to starspots are restricted to stars brighter than a critical absolute visual ...

Advanced Science, EarlyView.We developed a senolytic approach using procyanidin C1 (PCC1)‐loaded platform, a clinically established and safe hyaluronic acid‐based scaffold, to selectively eliminate senescent endothelial and microglial cells. This dual‐targeting strategy significantly suppresses pathological neovascularization and promotes vascular repair, presenting a safe and ...

Worm‐Inspired Soft Robots With Modular Outfit‐Changing for Intelligent Multienvironment Adaptation
Advanced Intelligent Systems, EarlyView.This study proposes a worm‐inspired soft robot capable of locomotion across multiple environments through a modular “outfit‐changing” strategy. The robot integrates pneumatically actuated peristaltic segments with interchangeable external modules, enabling efficient motion on ground surfaces, within pipelines, through granular media, and underwater ...

Molecular Hydrogen Controls the Temperatures of Flares on TRAPPIST-1
The Astrophysical Journal LettersEarly JWST observations of TRAPPIST-1 have revealed an unexpected puzzle: energetic white-light flares ( E > 10 ^30 erg) reach temperatures of only ∼3500–4000 K, nearly 3 times cooler than typical solar flares, which peak around 9000–10,000 K.

Flare in Late-type Stars: UV [PDF]
International Astronomical Union Colloquium, 1995 Early studies of stellar flares were made entirely in the optical regime. It was recognised that flares arose from the generation of hot plasma within the stellar chromosphere at whose temperature (indicated, for instance, by the presence of a strong, blue optical continuum) a substantial emission in the ultraviolet would be expected.

American Journal of Community Psychology, EarlyView.Abstract Mobile technologies have become significant resources for crisis communication and social support in recent years. However, despite empirical evidence pointing to the centrality of these technologies for parenthood in everyday life, it is yet unknown how parents' coping resources play a role in the digital environment.

Time-dependent Stellar Flare Models of Deep Atmospheric Heating
The Astrophysical JournalOptical flares have been observed from magnetically active stars for many decades; unsurprisingly, the spectra and temporal evolution are complicated.

Advanced NanoBiomed Research, EarlyView.This review highlights how autoimmune diseases arise from intertwined immunological, genetic, and environmental factors, emphasizing gut microbiota dysbiosis as a pivotal driver. It outlines emerging nanotechnology‐based strategies—such as liposomes, hydrogels, and polymeric nanoparticles—that enhance targeted drug delivery, minimize systemic toxicity,
