The aim of this paper is to consider the problems of TCP performance in broadband GEO satellite networks and to propose a crosslayer approach for a transport-layer PEP that makes spoofing actions on ACKs to modify them in case the satellite network is congested. This approach is investigated here from the signaling standpoint with a special attention to the BSM reference model and considering a...

Satellite cells play a central role in mediating the growth and regeneration of skeletal muscle. However, whether satellite cells are stem cells, committed progenitors, or dedifferentiated myoblasts has remained unclear. Using Myf5-Cre and ROSA26-YFP Cre-reporter alleles, we observed that in vivo 10% of sublaminar Pax7-expressing satellite cells have never expressed Myf5. Moreover, we found tha...

The satellite cells are long regarded as heterogeneous cell population, which is intimately linked to the processes of muscular recovery. The heterogeneous cell population may be classified by specific markers. In spite of the significant amount of variation amongst the satellite cell populations, it seems that their activity is tightly bound to the paired box 7 transcription factor expression,...

For future commercial broad-band data satellite networks, satellite network topology, link capacity, and routing have major impacts on the cost of the network and the amount of revenue the network can generate. In this thesis, we establish a mathematical framework, using two-stage stochastic programming, to assist network designers in selecting the most cost-effective network topology for data ...

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...

The sixth generation (6G) of mobile network will be composed by different nodes, from macro-devices (satellite) to nano-devices (sensors inside the human body), providing a full connectivity fabric all around us. These heterogeneous nodes constitute an ultra dense managing tons information, often very sensitive. To trust services provided such network, security is mandatory feature design. In t...

Satellite clock offset is an important factor affecting the accuracy of real-time precise point positioning (RT-PPP). Due to missing service (RTS) products provided by International GNSS Service (IGS) or network faults, users may not obtain effective corrections, resulting in unavailability RT-PPP. Considering this issue, improved back propagation (BP) neural optimized heterogeneous comprehensi...

The paper began proposing two possible frameworks where the different solutions to improve the performance of the transport layer over satellite channels may be classified: the Black Box (BB) approach and the Complete Knowledge (CK) approach. The former implies that only the end terminals may be modified; the rest of the network is considered non-accessible (i.e. a black box). The latter allows...
