TO THE EDITOR: We thank Snijders et al. (5) for raising important questions worthy of further discussion. In our study, 14 days of bed rest induced robust myofiber atrophy and muscle weakness that was accompanied by a reduction in satellite cell content (1). Individual changes in satellite cell quantity were significantly correlated with the decline in myofiber cross-sectional area after bed re...

Remote sensing has changed modern oceanography by proving synoptic periodic data which can be processed. Since the satellite data are usually too much and nonlinear, in most cases, it is difficult to distinguish the patterns from these images. In fact, SOM (Self-Organizing Maps) model is a type of ANN (Artificial Neural Network) that has the ability to distinguish the efficient patterns from th...

Image Quality of spacecraft sensors vary between ground pre-launch measure, after launch and over satellite lifetime due to launching vibration and space harsh environment. Due to the inaccessibility of the satellite on orbit, it is mandatory to use indirect method in order to estimate satellite performances. The aim of this work is to estimate the Image Quality of satellite by using the sharp ...

Satellite ground track display computer program is designed and implemented for the KOMPSAT-2 mission operations. Digitized world map and detailed Korean map is realized with zoom and pan capability. The program supports real-time ground trace and off-line satellite image planning on the world map. Satellite mission timeline is also displayed with the satellite ground track for the visualized m...

one of the most important information in urban forestry is acquaintance of urban landscape’s area or proportion. nowadays, in several countries variable methods are used to achieve this aim. since there is not any complete method to study urban forest’s status in iran, it is impossible to exert authentic management for these resources. hence, in this research, sampling methods and ikonos satell...

A satellite, in its orbit, is affected by perturbing forces, such as atmospheric drag, solar radiation pressure, Earth oblateness, and gravity of the celestial masses (other than the Earth). In this paper, the effects of these forces on the trajectories of different types of LEO satellites and a sample satellite (Z-SAT) are discussed. A few analyses are done on these orbits and the relevant res...

BACKGROUND Significant consequences of severe burn include skeletal muscle atrophy and heterotopic ossification (HO). The cellular mechanisms underlying either of these conditions are not known. Whether the functionality of satellite cells stem cells resident in skeletal muscle is affected by changes in circulatory factors following burn was determined to better understand their role in atrophy...

Path radiance due to aerosols plays an important role over satellite derived reflectance due to higher aerosol optical depth and their seasonal variations. In addition, satellite data from high-resolution sensors are subjected to adjacency effect, which reduces apparent surface contrast by decreasing the top of the atmosphere radiance over bright pixels and increasing the brightness of the dark...
