Matroshka DOSTEL measurements onboard the International Space Station (ISS)

Journal of Space Weather and Space Climate, 2015
This paper presents the absorbed dose and dose equivalent rate measurements achieved with the DOSimetry TElescope (DOSTEL) during the two Matroshka (MTR) experiment campaigns in 2004/2005 (MTR-1) and 2007/2008 (MTR-2B). The comparison between the inside (

Genomic and Epidemiological Characterization of DENV‐1 and DENV‐2 Co‐Circulation During the 2023–2024 Dengue Epidemic in Espírito Santo, Brazil

Journal of Medical Virology, Volume 98, Issue 8, August 2026.
ABSTRACT In 2023 and 2024, Espírito Santo state, Brazil, experienced its largest dengue epidemic in 30 years, with record numbers of cases and deaths. This study aimed to characterize confirmed dengue cases and the dengue virus (DENV) during the epidemic and pre‐epidemic periods.

Long‐Term Observations of Galactic Cosmic Ray LET Spectra in Lunar Orbit by LRO/CRaTER

Space Weather, 2020
The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) has been orbiting the Moon since 2009 aboard the Lunar Reconnaissance Orbiter (LRO). From this vantage point, it samples the interplanetary energetic particle population outside the shielding

Near‐Earth Cosmic Ray Modulation Index ϕ and Neutron Monitor Cutoff Rigidities at Hourly Cadence: Toward an Improved Monitoring of Solar‐Terrestrial Radiation Environment, Space Weather, and Space Climate

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic rays (CRs) are energetic particles originating from galactic and extragalactic sources. When arriving into the solar system and the Sun's heliosphere, they are diverted and modulated by the magnetic activity of the Sun. This modulation can be quantified by the modulation parameter ϕ $\phi $ determined with the Force‐field approximation (

Quantitative Control of Transposable Elements: From Genome Plasticity to Immune Regulatory Circuits

Cell Biochemistry and Function, Volume 44, Issue 7, July 2026.
ABSTRACT Transposable elements (TEs) constitute nearly half of the human genome and are increasingly recognized as context‐dependent regulators of genome function rather than passive repetitive DNA. This Review synthesizes classical and recent evidence on TE biology, including TE classification, mechanisms of mobilization, host restriction pathways ...

Epitaxial Growth Mechanism and Magnetic Properties of Heterogeneous Core–Shell Grains in (Nd, Y)‐Fe‐B Alloys

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The construction of core–shell grains can enhance the coercivity of Nd2Fe14B magnets. However, it is a significant challenge to elucidate the formation of these core–shell grains particularly regarding the spontaneous core–shell structure in Y‐substituted Nd2Fe14B alloys.

Simulation of subsurface particle radiation and leakage flux on the moon from solar energetic particles and galactic cosmic rays

European Physical Journal C: Particles and Fields
The moon is continuously bombarded by cosmic rays, primarily Galactic Cosmic Rays (GCR) and Solar Cosmic Rays, which generate complex secondary radiation in the lunar subsurface.

Aircraft Ionizing Radiation Exposure for Solar Cycle 24/25 From ARMAS and NAIRAS

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Exposure to ionizing radiation from galactic cosmic rays and solar energetic particles at aviation flight altitudes can have an adverse effect on human health. Although airline crews are classified as radiation workers by the International Commission on Radiological Protection (ICRP), in most countries, their level of exposure is unquantified ...

Modeling of the Near-Earth Low-Energy Antiproton Fluxes

Advances in Astronomy, 2011
The local interstellar antiproton spectrum is simulated taking into account antineutron decay, (He,p) interaction, secondary and tertiary antiproton production, and the solar modulation in the “force field” approximation.
