Using Extreme Value Theory for Determining the Probability of Carrington‐Like Solar Flares [PDF]

open access: yes, 2016
By their very nature, extreme space weather events occur rarely, and therefore, statistical methods are required to determine the probability of their occurrence.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Distribution of low-power solar flares by brightness rise time

open access: yesSolar-Terrestrial Physics, 2018
Using data from the international flare patrol for 1972–2010, we have formed an electronic database for more than 123 thousand solar flares. We determined the mean brightness rise time (flash phase) for flare area classes and importance. We show that the

The Anomalous Temporal Behaviour of Broadband Ly$\alpha$ Emission During Solar Flares From SDO/EVE

open access: yes, 2015
Despite being the most prominent emission line in the solar spectrum, there has been a notable lack of studies devoted to variations in Ly$\alpha$ emission during solar flares in recent years. However, the few examples that do exist have shown Ly$\alpha$

COMPTEL solar flare measurements [PDF]

open access: yes, 1996
We review some of the highlights of the COMPTEL measurements of solar flares. These include images of the Sun in γ rays and neutrons. One of the important features of the COMPTEL instrument is its capability to measure weak fluxes of γ rays and neutrons ...

Spatio-temporal Dynamics of Sources of Hard X-Ray Pulsations in Solar Flares [PDF]

open access: yes, 2016
We present a systematic analysis of the spatio-temporal evolution of sources of hard X-ray (HXR) pulsations in solar flares. We concentrate on disk flares whose impulsive phases are accompanied by a series of more than three successive peaks (pulsations)

Stable Nitrogen Isotope Analysis of Amino Acids by Orbitrap Mass Spectrometry: Application for Extraterrestrial Samples

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 23, 15 December 2025.
ABSTRACT Background Obtaining isotopic data on soluble organic compounds, such as amino acids, in extraterrestrial samples is crucial for understanding their origins, prebiotic chemistry, and potential contamination. Conventional GC‐IRMS requires grams of material to measure isotopic compositions, limiting the analysis of low‐concentration organics in ...

Long‐Term Real‐World Effectiveness of Rupatadine in Chronic Urticaria: A Retrospective Observational Study

open access: yesJEADV Clinical Practice, Volume 4, Issue 5, Page 1025-1032, December 2025.
This retrospective observational study analyzed a cohort of chronic urticaria (CU) patients to provide insight into the clinical practice of CU with second‐generation antihistamines (SgAHs) and to evaluate the long‐term real‐world effectiveness of rupatadine in CU. Patients with chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU)

A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.
