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

Experimental 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 ...

Survival of the Accretion Disk in LMC Recurrent Nova 1968-12a: UV–X-Ray Case Study of the 2024 Eruption

The Astrophysical Journal
We report on UV and X-ray observations of the 2024 eruption of the recurrent nova LMCN 1968-12a, a rapidly recurring extragalactic system with a ∼4.3 yr recurrence period and a massive white dwarf. The eruption was discovered on 2024 August 1.8 by Swift,

Measurement of the volume CT dose index on spiral CT scanning with a real‐time ionization chamber

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background The measurement of computed tomography dose index 100 (CTDI100$CTD{{I}_{100}}$), which is feasible only through axial scanning, requires that the clinical spiral protocols be replaced with those for axial scanning. The real‐time ionization chamber detects the integral of radiation dose rate profile, enabling the direct verification ...

Constraints on the X-Ray and Very-high-energy Gamma-Ray Flux from Supernova Remnant W44

The Astrophysical Journal
Observations of GeV gamma-ray emission from the well-studied mixed-morphology supernova remnant (SNR) W44 by Fermi-Large Area Telescope and AGILE imply that it is a site of significant cosmic-ray acceleration.

Selective vignetting of Type 1 X-ray telescopes [PDF]

, 1969
Selective vignetting technique optimizes the performance of a Type 1 X-ray telescope. The image quality of the telescope system is improved by matching the detector to the optimum focal surface and by vignetting rays which formerly contributed to the ...

Bursty Precipitation of Relativistic Electrons Unveiled by CIRBE/REPTile‐2 Measurements and Their Physical Implications

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Energetic electron precipitation plays a pivotal role in shaping Earth's radiation belt dynamics and drives significant physical and chemical changes in the upper atmosphere. However, the detailed mechanisms governing the loss of relativistic electrons have remained unclear, largely due to the limited energy coverage and coarse resolution of ...
