Microvascular Health as a Key Determinant of Organismal Aging

open access: yesAdvanced Science, Volume 12, Issue 47, December 18, 2025.
Abstract Aging is a complex, multifaceted process affecting all organ systems, with vascular aging playing a central role in organismal health decline. Beyond its role in circulation, the vascular system acts as a dynamic interface between tissues, influencing countless physiological functions such as tissue regeneration and repair, immune responses ...

Review of Analytical Lithium Detection and Quantification Methods Along the Lithium Value Chain

open access: yesApplied Research, Volume 4, Issue 6, December 2025.
This article reviews a selection of suitable state‐of‐the‐art analytical methods for different scales of spatial resolution and detection of lithium for a variety of lithium‐bearing materials along the lithium value chain. The various materials differ greatly in terms of their lithium content by more than 5 orders of magnitude and also vary in their ...

The origin of cosmic rays and TeV gamma-ray astronomy

open access: yesEPJ Web of Conferences, 2013
Cosmic rays are accelerated to high energies in Galactic and extragalactic objects like Supernova remnants (SNR) and active galactic nuclei (AGN). How these accelerators work and how efficient they accelerate different types of particles to energies of ...

INTERACTION OF SUPERNOVA BLAST WAVES WITH WIND-DRIVEN SHELLS: FORMATION OF

open access: yesOdessa Astronomical Publications, 2017
Most of middle-aged supernova remnants (SNRs) have a distorted and complicated appearance which cannot be explained in the framework of the Sedov-Taylor model.

Revisiting γ-Ray Emission of the Supernova Remnant RCW 103

open access: yesThe Astrophysical Journal
We analyze more than 15 yr of γ -ray data obtained with the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope (Fermi) for the region of the young supernova remnant (SNR) RCW 103, since the nearby source 4FGL J1616.2−5054e ...

Positron Annihilation Spectroscopy of Young Supernova Remnants

open access: yesOdessa Astronomical Publications, 2018
This paper discusses radiative and thermodynamic properties of cold rarefied aggregates of non-uniformly distributed gas and dust through which high fluxes of positrons with energies of 0.011-3.6 MeV pass.

Mapping the Dense Molecular Gas toward 13 Supernova Remnants

open access: yesThe Astrophysical Journal
Supernova remnants (SNRs) can exert strong influence on molecular clouds (MCs) through interaction by shock wave and cosmic rays. In this paper, we present our mapping observation of HCO ^+ and $\mathrm{HCN}$ 1–0 lines toward 13 SNRs interacting with MCs,
