We derive a value of about 10 . The second experiment deals with the release rate of adsorbed H 2 from the Ti film by He + of Ar + ion bombardment using a residual gas analyzer. The intention was to simulate the hydrogen recycling from tokamak walls by plasma irradiation. We obtained a...
As ASIM is mounted on the International Space Station (ISS), which is orbiting at about 400 km altitude with a 51.6° inclination, it will reach the latitudes where particles from the radiation belt and auroral particles precipitate in the upper atmosphere. While auroral observations and ...

However, the ability to distinguish between different models depends critically on the capability to point to the target location and start monitoring the emission early, about an hour after receiving the gravitational wave signal. In the case of GW170817, which represents the current state of the ...

Active VHF radiations are detected in about 70 % of optical observations without obvious regional or seasonal dependency. Estimations of the EM direction-of-arrival (DOA) are attempted using the broadband digital interferometry. Some results agree with the optical observations, even though DOA ...
These indirect measurements are the first ones made on the continental shelf off the Antarctic Peninsula. They indicate a submarine ridge of about 150 to 300m water depth nearly perpendicular to the coastline at about 70掳 45掳 S between 56掳 30掳 Wand 58掳 30'' W.doi:10.1080/...
Radars performing observations of resident space objects (RSO) measure Doppler variations in wave events of several minutes duration, with frequencies in the 0.2–1 Hz range peaking near 0.5–0.7 Hz, consistent with variations in electron density induced by waves in the intervening ionosphere. The ...
The real challenge about Huygens' synchronization is 'enclosed' in the orange circles in Fig. 1. It should be noted that a proper mathematical model has not been derived yet. Current models are an oversimplification of the real Huygens' system, in part because the coupling structure has ...
