Generation of Cosmic rays in Historical Supernova Remnants

open access: yesEPJ Web of Conferences, 2013
We present the results of observations of two types of Galactic supernova remnants with the SHALON mirror Cherenkov telescope of Tien-Shan high-mountain Observatory: the shell-type supernova remnants Tycho, Cas A and IC 443; plerions Crab Nebula, 3c58 ...

Nowcasting Solar Energetic Particle Events for Mars Missions

open access: yesSpace Weather, Volume 23, Issue 4, April 2025.
Abstract In addition to the omnipresent Galactic Cosmic Rays, sudden Solar Energetic Particle (SEP) events present considerable health hazards for manned space missions. These events not only contribute to an increased long‐term cancer risk, but can, in extreme cases, cause acute radiation syndromes.

SARS‐COV‐2 Pre‐Exposure Prophylaxis With Tixagevimab‐Cilgavimab in Haematological, Immunocompromised Patients in the Omicron Era

open access: yesEuropean Journal of Haematology, Volume 114, Issue 4, Page 690-699, April 2025.
ABSTRACT Background Pre‐exposure prophylaxis with tixagevimab‐cilgavimab significantly reduced severe COVID‐19 outcomes in high‐risk individuals during the pre‐Omicron era (PROVENT trial). However, efficacy in patients with haematological malignancies (HM) was underreported.

Shock‐heated graphite in three IAB iron meteorites—Implications on the formation of diamond

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 4, Page 744-756, April 2025.
Abstract Iron meteorites, originating from the deepest parts of their parent bodies and separated during major break‐up events, surprisingly rarely contain diamonds despite experiencing similar pressure–temperature conditions as diamond‐bearing ureilites. In this study, graphite from three non‐magmatic IAB iron meteorites Canyon Diablo, Campo del Cielo,

Diaminotriazinyl‐Substituted N‐Heterotriangulene: Hydrogen Bonding‐Driven Self‐Assembly in the Solid State, in the Gas Phase and on Surfaces

open access: yesChemistry – A European Journal, Volume 31, Issue 18, March 25, 2025.
Dimethylmethylene‐bridged N‐heterotriangulene with lateral diaminotriazinyl groups was developed as a versatile building block for robust self‐assembly via self‐complementary hydrogen bonding under ambient conditions. Comprehensive mass spectrometry experiments, X‐ray diffraction and scanning probe microscopy techniques were used to investigate the ...
