Advanced Science, EarlyView.MethyAnno enables robust and interpretable annotation of single‐cell DNA methylation data by integrating multi‐scale epigenetic information, bidirectional cross‐attention, and prototype‐based metric learning. The framework resolves rare and novel cell types across datasets while revealing cell‐type‐specific epigenetic signatures associated with disease

The Mass Dependence of Hα Emission and Stellar Spindown for Fully Convective M Dwarfs
The Astrophysical JournalFully convective M dwarfs typically remain rapidly rotating and magnetically active for billions of years, followed by an abrupt and mass-dependent transition to slow rotation and quiescence.

Extending the Search for Counterrotating Gas and Stars in Galaxies: A Study of Late-Type Dwarfs
, 2005 In a previous study on gas-stellar counterrotation for a large sample of E/S0 and spiral galaxies (Kannappan & Fabricant 2001), two dwarf irregular galaxies were included, of which one was tentatively identified as a counterrotator. Here we extend the search for counterrotation to include 10 more irregular/spiral dwarf galaxies.

AFar Ultraviolet Spectroscopic ExplorerSurvey of Late‐Type Dwarf Stars
The Astrophysical Journal, 2002 We describe the 910-1180 Aspectra of seven late-type dwarf stars obtained with the Far Ultraviolet Spec- troscopic Explorer (FUSE) satellite. The stars include Altair (A7 IV), Procyon (F5 IV-V), Cen A (G2 V), AB Dor (K1 V), Cen B (K2 V), Eri (K2 V), and AU Mic (M0 V). We present line identifications, fluxes, Doppler shifts, and widths.

Ab Initio Thermoelectric Transport Calculations of Alloyed Half‐Heuslers
Advanced Science, EarlyView.The effect of alloying on the electronic transport of half‐Heusler thermoelectric materials is explored using a fully ab initio approach. A novel method is developed that combines calculations of alloyed supercells with Boltzmann transport, considering the full energy and momentum dependent scattering processes from first principles extracted ...

The Influence of Chromospheric Activity on Line Formation
The Astrophysical JournalOne of the primary sources of stellar spectral variability is magnetic activity. While our current understanding of chromospheric activity is largely derived from specific lines sensitive to chromospheric heating, such as the Ca ii H and K doublet ...

Studies of late-type dwarfs. V - Theoretical models for lower main-sequence stars
The Astrophysical Journal, 1983 New theoretical stellar models for the lower end of the main sequence have been computed for a wide range in metallicity. These models are based on new low-temperature opacities, which include the contributions from the most important molecules, as well as published model atmospheres, which guided the choice of surface boundary conditions.

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 ...
