TUUSAT-1A stands for Taiwan Universities United Satellite NO.1A. The micro-satellite research team includes scholars from Tamkang University, China Institute of Technology, National Formosa University, National Taiwan Ocean University and National Chia Yi University. The micro-satellite is 28 cm in height and weighs 40 kg and it is powered by solar energy. For image acquisition using GPS and CM...

Skeletal muscle satellite cells are considered to play a crucial role in muscle fiber maintenance, repair and remodeling. Our knowledge of the role of satellite cells in muscle fiber adaptation has traditionally relied on in vitro cell and in vivo animal models. Over the past decade, a genuine effort has been made to translate these results to humans under physiological conditions. Findings fro...

A satellite DNA family (APSU) was isolated and characterized in the ant Aphaenogaster subterranea. This satellite DNA is organized in tandem repeats of 162 bp and is relatively AT rich (51.9%). Sequence analysis showed a high level of homogeneity between monomers. Loss of satellite DNA has been detected in queens in relation to workers, because the amount of satellite DNA in queens is about 25%...

Recalling the Palapa domestic satellite system, as a breakthrough technology for assessing isolated areas, and triggering business activities. INTELSAT commenced the opening of new horizons for reliable international satellite communication, and Indonesia took a wise decision to join, notwithstanding its economic hardships. Indonesia, had to take crucial decisions during ITU WARC-ORB ‘85 and ’8...

Recently, earth observation system by using satellite network have attracted much attention due to their wide coverage and disaster resistance. Although the system is useful for collecting various data, which have an affect on a natural disaster, ecology and so forth, earth observation satellite hardly send the collected observation data to the ground station. This is because that the earth obs...

Satellite cells represent the stem cell population of adult skeletal muscle. The molecular mechanisms that control the proliferation of satellite cells are not well understood. In this study, we show that in response to injury, myofibres activate Wnt ligand transcription and activate a reporter cell line that is sensitive to the canonical Wnt-signalling pathway. Activated satellite cells on iso...

Low Earth Orbit Satellite Networks can augment terrestrial wireless networks to provide global broadband services to users regardless of the users’ locations. Delivering QoS guarantees to the users of LEO satellite networks is complicated since footprints of LEO satellites move as the satellites traverse their orbits, and thus, causing frequent user handovers between the satellites. Traffic on ...

I calculate the action of a satellite, infalling through dynamical friction, on a coplanar gaseous disk of finite radial extent. The disk tides, raised by the infalling satellite, couples the satellite and disk. Dynamical friction acting on the satellite then shrinks the radius of the coupled satellite-disk system. Thus, the gas is “shepherded” to smaller radii due to the action of dynamical fr...

A wide variety of network applications require the use of reliable multicast protocols to disseminate data from one source to a potentially large number of receivers simultaneously. Broadband satellite is an ideal transmission medium to support such applications. Although several reliable multicast protocols have been proposed for the Internet, they are not optimized for satellite networks, and...

This paper discusses in-house designed and developed scale-down DVB-RCS hub along with the performance of the realized hub. This development is intended to support the Satellite Based e-Learning initiative in India. The scale-down DVB-RCS HUB is implemented around a single PC with other subsystems making it very cost effective and unique of its kind. This realization will drastically reduce the...
