Research on ICCD for space observation of cosmic ray and dark matter

open access: yes, 2014
The low light level imaging and ultrafast detection system is a high performance ICCD composed of imaging intensifier and high-frame-rate CCD, the important readout system of the semi-digital 3D-imaging calorimeter for space observation of cosmic ray and

Analysis of Galactic Cosmic Ray Variability and Time-Lagged Relation to Solar Activity

open access: yes
The study of galactic cosmic ray variations and their connection to solar activity has been explored using various methods, such as cross-correlation analysis, which measures the synchronization between time series peaks, and power spectral density or ...

A search for TeV gamma ray emission from X-ray binary stars [PDF]

open access: yes, 1993
This work is concerned with the detection of pulsed TeV gamma ray emission from a number of X-ray binary systems by the use of the atmospheric Cerenkov technique.

Cosmic Ray Radiography [PDF]

open access: yes
On the analogy of X-ray or gamma-ray radiography, it is shown that cosmic radiations are applicable to non-destructive estimations of various environment materials closely concerned with human life.

Methods for Tracking Cosmic-Ray Spectral Changes Using Neutron Monitors at High Cutoff Rigidity

open access: yesThe Astrophysical Journal
Neutron monitors are a standard tool for high-precision monitoring of changes in the Galactic cosmic ray (GCR) flux that occur as a result of variations of the heliospheric conditions and solar storms.

Women in space: A review of known physiological adaptations and health perspectives

open access: yesExperimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Topics in Energy Release and Particle Acceleration in the Heliosphere

open access: yes, 2014
This thesis investigates both the release of energy in solar flares, and the acceleration and transport of particles in various astrophysical situations.

Radio emission of cosmic-ray air showers at the South Pole and a new icetop trigger

open access: yes
Schroeder, Frank G.The sources of highly energetic cosmic rays are still not fully understood. Better accuracy in composition measurement at different energies is essential to establish the origin of these energetic particles.

Computer modeling and experimental work on the astrobiological implications of the martian subsurface ionising radiation environment [PDF]

open access: yes, 2008
Any microbial life extant in the top meters of the martian subsurface is likely to be held dormant for long periods of time by the current permafrost conditions.

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 ...
