The search for the ultimate exercise countermeasure to preserve crew health and ensure mission success in long‐duration spaceflight

Experimental Physiology, EarlyView.
Abstract The current understanding of crew health maintenance is founded upon decades of physiological research conducted in terrestrial spaceflight analogues and in low Earth orbit, particularly on the International Space Station. However, as we progress towards the Lunar Gateway and interplanetary missions, it is imperative that the tools employed to

Submillimeter Spectrum of the Cosmic Background Radiation [PDF]

Highlights of Astronomy, 1989
Recent observations of the spectrum of the 3K cosmic background radiation (CBR) indicate that the CBR spectrum is consistent with a blackbody spectrum of T = 2.74 ±0.02K (Smoot et al. 1987). These measurements, however, were carried out in the Rayleigh-Jeans part of the spectrum, while theories predict spectral distortion in the Wien part.

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 ...

The Atacama Cosmology Telescope: Millimeter Observations of a Population of Asteroids or: ACTeroids

The Astrophysical Journal
We present fluxes and light curves for a population of asteroids at millimeter wavelengths, detected by the Atacama Cosmology Telescope (ACT) over 18,000 deg ^2 of the sky using data from 2017 to 2021.

Wilms Tumor in Children With AMER1/WTX Germline Pathogenic Variants: A Multicenter Case Series

Pediatric Blood &Cancer, Volume 72, Issue 8, August 2025.
ABSTRACT Background 10–15% of children with Wilms tumor (WT) have predisposing genetic syndromes. Somatic mutations are frequently identified; however, germline pathogenic variants in AMER1 are much less prevalent and are associated with osteopathia striata with cranial sclerosis (OSCS).

Changes of Poleward Oceanic Heat and Salt Transport Associated With the Central Eurasian Seaway During the Early Paleogene

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract During the early Paleogene, the Arctic Ocean existed in a warm yet restricted freshwater regime, with episodic strong freshening leading to proliferation of the freshwater‐adapted Azolla at basal middle Eocene times (49–48 Ma). The Kara Strait, located between the Arctic Ocean and the West Siberian Sea (WSS), facilitated an open central ...

Design of Waveguide NbN‐Based Superconductor–Insulator–Superconductor Mixer for 650 GHz

Advanced Photonics Research, Volume 6, Issue 7, July 2025.
This research work focuses on a waveguide NbN‐based superconductor–insulator–superconductor mixer operating at 650 GHz. The signal coupling circuit is designed using a waveguide‐microstrip coupling structure, and the return loss obtained is lower than −16 dB. For the mixing circuit, its return loss is less than −7.5 dB, and the return loss reduces with

SCALING PROPERTIES OF THE COSMIC BACKGROUND PLASMA AND RADIATION [PDF]

International Journal of Modern Physics D, 2003
Scaling properties of the cosmic microwave background (CMB) radiation are studied using satellite (COBE-DMR maps), balloon-borne and ground-based (combined QMASK map) data. Quantitative consistency is found between the multiscaling properties of the COBE-DMR and QMASK CMB maps.
