A Bayesian method for detecting stellar flares [PDF]
, 2014 We present a Bayesian-odds-ratio-based algorithm for detecting stellar flares in light-curve data. We assume flares are described by a model in which there is a rapid rise with a half-Gaussian profile, followed by an exponential decay.

Solar and stellar flares and their connection [PDF]
This thesis focuses on bridging the gap between solar and stellar physics through the study of flares. Solar flares are the most powerful explosions in the solar system and many stellar flares have been observed to be orders of magnitudes larger ...

Advances in Understanding Solar and Stellar Flares
, 2016 Flares result from the sudden reconnection and relaxation of magnetic fields in the coronae of stellar atmospheres. The highly dynamic atmospheric response produces radiation across the electromagnetic spectrum, from the radio to X-rays, on a range of ...

Making the Case for Organ‐on‐Chip Platforms in Long‐Acting Therapeutics Development
Advanced Healthcare Materials, EarlyView.LATs release drug from a tissue‐resident depot over weeks to months, improving adherence, but their development is hampered by preclinical models that cannot reproduce the coupled tissue processes, sustained release, local microenvironment change, interstitial transport, immune and foreign‐body responses, and clearance that govern depot performance in ...

Helium Ion‐Induced Degradation Mechanisms in Optical Coatings for Space Applications
Advanced Optical Materials, EarlyView.Although low‐energy helium ions represent a significant source of degradation for optical coatings operating in space environments, their effects remain poorly understood. Systematic irradiation of over 150 metal and dielectric thin‐film samples at 4, 16, and 100 keV investigates the damage mechanisms and their impact on optical performance ...

A Statistical Study of Soft X-Ray Flares on Solar-type Stars
The Astrophysical JournalThe statistical characteristics of stellar flares at optical bands have received extensive study, but they remain to be studied at soft X-ray bands, in particular for solar-type stars.

Thermochemical Micro‐Explosion for Prompt Thrombolysis via Proximal Injection of Liquid Alkali Metal
Advanced Science, EarlyView.We report a micro‐explosive thermochemical thrombolysis (METCT) therapy via injectable liquid alkali metal encapsulated in dimethyl silicone (LAM@oil). METCT enables prompt and safe vascular recanalization within 90 s. Critically, the LAM@oil system demonstrates significantly higher thrombolytic efficacy compared to clinically available thrombolytic ...

Advanced Science, EarlyView.Nanomaterials offer dual applications in allergy management. For diagnosis, nanomaterials enhance analytical sensitivity and improve detection in specific IgE and functional assays such as the basophil activation test (BAT). For allergen‐specific immunotherapy, nanomaterials enable allergen masking and controlled release, and effectively modulate the ...
