Scalable, Advanced Machine Learning Based Approaches for Stellar Flare Identification: Application to TESS Short-cadence Data and Analysis of a New Flare Catalog

The Astronomical Journal
We apply multialgorithm machine learning models to TESS 2 minute survey data from Sectors 1–72 to identify stellar flares. Models trained with deep neural network, random forest, and XGBoost algorithms utilize four flare light-curve characteristics as ...

X-Ray Analysis of Gamma-Ray Burst Flares and Underlying Afterglows: Insights into the Origin of Flares

The Astrophysical Journal
Gamma-ray burst (GRB) X-ray light curves exhibit a variety of complex temporal structures, such as flares and plateaus. The origin of flares seen in many GRB early afterglows is still uncertain. Here we analyze a sample of 89 GRBs, 61 of them with flares,

Human biomarker navigator

iMeta, Volume 5, Issue 5, October 2026.
The Human Biomarker Navigator integrates the disease continuum, biomarker dynamics, cross‐organ biomarker networks, biomarker classification, and technology‐driven paradigms. It maps how biomarkers link multi‐system physiology and pathology across the nervous, respiratory, endocrine, circulatory, immune, digestive, urinary, reproductive, and ...

Functional Adaptations for Load‐Bearing in a Dermal Bone: The Pectoral Fin Spine of the Russian Sturgeon (Huso Gueldenstaedtii)

Journal of Morphology, Volume 287, Issue 10, October 2026.
The pectoral fin spine (PFS) of the sturgeon is a robust dermal skeletal element that extends laterally and is located on the leading edge of the pectoral fin. The PFS is a load‐bearing dermal bone composed of peripheral parallel‐fibered bone and dermal osteonal bone organized around an interconnected neurovascular network.

A Long-duration Superflare on the K Giant HD 251108

The Astrophysical Journal
Many giant stars are magnetically active, which causes rotational variability, chromospheric emission lines, and X-ray emission. Large outbursts in these emission features can set limits on the magnetic field strength and thus constrain the mechanism of ...

Understanding higher‐order aberrations in keratoconus

Optometry and Vision Science, Volume 103, Issue 10, October 2026.
ABSTRACT Keratoconus is characterized by progressive thinning and increasing irregularity of the cornea, leading to substantial degradation in optical quality through the induction of both lower‐ and higher‐order aberrations (HOAs). In addition to inducing myopic and astigmatic refractive error, asymmetric corneal steepening generates complex optical ...

Sun-as-a-star Analysis of the X1.6 Flare on 2023 August 5: Dynamics of Postflare Loops in Spatially Integrated Observational Data

The Astrophysical Journal Letters
Postflare loops are loop-like plasmas observed during the decay phase of solar flares, and they are expected to exist for stellar flares. However, it is unclear how postflare loops are observed in stellar flares’ cases.
