The Vertical Metallicity Gradient of the Galactic Disk for Mono-age Stellar Populations in LAMOST
The Astrophysical JournalThe vertical metallicity gradient of the Galactic disk offers valuable insights into the disk’s formation and chemical evolution over time. We utilized the Large Sky Area Multi-Object Fibre Spectroscopic Telescope low-resolution spectral young stellar ...

The Theory of Spiral Structure of Galaxies [PDF]
Symposium - International Astronomical Union, 1970 A Landau-type instability mechanism for generating spiral waves is suggested.Two populations of stars, Populations I and II, are considered, the second one with mean rotational velocity zero. Then a dispersion relation is derived which is reduced to the Lin-Shu dispersion relation in the case of vanishing Population II. The amplification of the wave is

Somato‐Cognitive Action Network in Focal Dystonia
Movement Disorders, EarlyView.Abstract Background The central pathology causing idiopathic focal dystonia remains unclear. The recently identified somato‐cognitive action network (SCAN) has been implicated. Objective We tested whether the effector‐agnostic SCAN may constitute a central pathology shared across dystonia subtypes, whereas the effector‐specific regions in the primary ...

Current understanding of electroautotrophy and its relevance in astrobiology‐related research
mLife, EarlyView.Abstract Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy. Its occurrence in deep‐earth and deep‐sea environments suggests profound implications for astrobiology, yet electroautotrophic microorganisms remain poorly explored ...
