Advanced Science, EarlyView.Refined data are extracted from CIF files to construct a hierarchical machine‐learning framework integrating sublattice classification, Fe‐site occupancy prediction, and reliability assessment. External validation yields 96% accuracy for sublattice classification and a macro mean absolute error of 0.0584 for Fe‐site prediction.

Asteroseismology of the Nearby K Dwarf σ Draconis Using the Keck Planet Finder and TESS
The Astrophysical JournalAsteroseismology of dwarf stars cooler than the Sun is very challenging owing to the low amplitudes and rapid timescales of oscillations. Here we present the asteroseismic detection of solar-like oscillations at 4-minute timescales ( ${\nu }_{\max }\sim ...

Comparative Insights and Overlooked Factors of Interphase Chemistry in Alkali Metal‐Ion Batteries
Advanced Energy Materials, EarlyView.This review presents a comparative analysis of Li‐, Na‐, and K‐ion batteries, focusing on the critical role of electrode–electrolyte interphases. It especially highlights overlooked aspects such as SEI/CEI misconceptions, binder effects, and self‐discharge relevance, emphasizing the limitations of current understanding and offering strategies for ...

Low Participation and Risk Reduction Potential of Supplemental Crop Insurance in the United States
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Federally subsidized crop insurance is a cornerstone of U.S. farm risk management, yet policies with the greatest share of participation only trigger indemnities after losses exceed 15%. Supplemental insurance was introduced to cover part of this deductible, but participation remains largely unchanged.

The Astronomical JournalThe fundamental parameters of a low-mass star can potentially be determined from its photometry and astrometry. This is complicated by the fact that 10%–20% of low-mass stars are predicted to be equal-mass binaries.

Agronomic and Nutritional Perspectives on Vegetable Crops in Africa
AgriFood: Journal of Agricultural Products for Food, EarlyView.Vegetable production plays a key role in food security, nutrition, and livelihoods across Africa. Moreover, African indigenous vegetables emerge as underutilized yet highly valuable crops, rich in macro‐ and micronutrients, as well as bioactive compounds with an array of health benefits.

A spectral differential characterization of low-mass companions
EPJ Web of Conferences, 2013 We present a new approach with which the dynamical mass of low-mass companions around cool stars can be found. In order to discover companions to late-type stars the stellar spectrum is removed.
