The empirical relations between rotation period, chromospheric activity, and age can be used to estimate stellar age. To calibrate these relations, we present a catalog, including the masses and ages of 52,321 FGK dwarfs, 47,489 chromospheric activit

The most common method for establishing bioequivalence (BE) is to demonstrate similarity of concentration–time profiles in the systemic circulation, as a surrogate to the site of action. However, similarity of profiles from two formulations in the

Using data from Gaia Data Release 3 and Kepler/K2, we present a catalog of 16 open clusters with ages ranging from 4–4000 Myr that provides detailed information on membership, binary systems, and rotation. We assess the memberships in 5D phase spac

Varying oxygen abundance could impact modeling-inferred ages. This work aims to estimate the ages of dwarfs considering observed oxygen abundance. To characterize 67,503 LAMOST and 4006 GALAH FGK-type dwarf stars, we construct a grid of stellar model

A ratiometric fluorescent sensor, Flu@Eu-dbia, was self-assembled through host–guest interaction for the detection of tyramine. Distinguishable color change and the logic gate endowed Flu@Eu-dbia with great potential in food safety monitoring.

Main Sequence Turn-off stars (MSTO) and subgiant stars are good tracers of galactic populations. We present a study of 41,034 MSTO and subgiant stars from the GALAH survey. Using a grid of stellar models that accounts for the variation of O abundance
