Global Navigation Satellite System performance can be significantly enhanced by introducing inter-satellite links (ISLs) in navigation constellation. The improvement in position, velocity, and time accuracy as well as the realization of autonomous functions requires ISL distance measurement data as the original input. To build a high-performance ISL, the ranging consistency among navigation sat...

introduction: satellite cells are known as the main regenerative cell type in skeletal muscles. our study established a modified digestion and preplating method for the isolation of slow or weak adherent cells for the enrichment of satellite cells. low-survival rate of these primary stem cells prompted us to address whether cell culture medium substitution might change cell viability status. me...

Satellite DNA profiles have been characterized in the congeneric species Palorus ratzeburgii, Palorus subdepressus, Palorus genalis, and Palorus ficicola (Coleoptera, Insecta), each of which contains a single, A + T-rich satellite DNA comprising a considerable portion of the genome (20%-40%). These satellites exhibit insignificant mutual sequence similarity. Using PCR assay, it has been shown t...

Low earth orbit (LEO) satellite has the advantages of global coverage, low propagation delay and low path losses, etc. Combined with orthogonal frequency division multiplexing (OFDM) transmission, LEO satellite system can support very high capacity suitable for wideband multimedia traffic. This paper analyzes the channel model and throughput for LEO OFDM satellite communication system. First, s...

One of the main factors for satellite design is simulating of total ionizing dose due to space ionizing rays in devices used in space. By measurement of induced dose based on available data in different altitudes, expenses of designing, satellite weight and amount of needed fuel will be reduced. Optimum design of satellite for protecting satellite against ionizing radiation has considerable eff...

Exposure to high levels of genotoxic stress, such as high-dose ionizing radiation, increases both cancer and noncancer risks. However, it remains debatable whether low-dose ionizing radiation reduces cellular function, or rather induces hormetic health benefits. Here, we investigated the effects of total-body γ-ray radiation on muscle stem cells, called satellite cells. Adult C57BL/6 mice were ...
