Updated model of cosmic-ray-induced ionization in the atmosphere (CRAC:CRII_v3): Improved yield function and lookup tables

Journal of Space Weather and Space Climate
Cosmic rays, including galactic cosmic rays and solar energetic particles, form the main source of ionization of the low and middle atmosphere, which is important for various chemical and physical effects in the atmosphere.

Mechanism study of an articular cartilage repair material and its forward‐looking test for space medicine

BMEMat, EarlyView.
The regeneration process following dLhCG engraftment progressed through four distinct and interconnected stages. dLhCG maintained its regenerative efficacy after 6 months of cosmic exposure, supporting its potential application in space medicine.

Evaluation of COSMIC‐2 Satellite Data for foF2 and hmF2 Against Ground‐Based Ionosondes and the PyIRI (2020) Model Across Middle to Low Latitudes

Space Weather
This study presents a comprehensive evaluation of COSMIC‐2 satellite‐derived ionospheric peak parameters (foF2 and hmF2) against ground‐based ionosonde observations and a comparative analysis with PyIRI (2020) model estimates across middle to low ...

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

Chemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Intravenous Lipopolysaccharide Challenge in Healthy Participants Reveals Pharmacodynamic Markers in Blood and Bone Marrow for Early‐Phase Oncology Drug Development

Clinical Pharmacology &Therapeutics, EarlyView.
Demonstrating pharmacological effects in early‐phase oncology clinical trials remains challenging, largely due to the lack of robust pharmacodynamic markers. Lipopolysaccharide (LPS) is used as an immune challenge agent in healthy participants to study drugs for autoimmune conditions.

High energy cosmic ray air showers and small-x QCD [PDF]

, 2005
We discuss that hadron-induced atmospheric air showers from ultra-high energy cosmic rays are sensitive to QCD interactions at very small momentum fractions x where nonlinear effects should become important.

Prospects for Detecting Cosmic Filaments in Lyα Emission across Redshifts z = 2–5

The Astrophysical Journal
The standard ΛCDM cosmological model predicts that a large amount of diffuse neutral hydrogen distributes in cosmic filaments, which could be mapped through Ly α emission observations.

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit

Contributions to Plasma Physics, EarlyView.
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.
