In the mid-1980's Rodney Brooks touched off a firestorm of interest in autonomous robots with the introduction of the Subsumption architecture1 [Brooks86]. At the time, the dominant view in the AI community was that a control system for an autonomous mobile robot should be decomposed into three functional elements: a sensing system, a planning system, and an execution system [Nilsson80]. The jo...

Umbilical cord blood (UCB) has been used for transplantation in the treatment of hematologic disorders as a source of hematopoietic stem cells (HSCs). Because of insufficient number of cord blood CD34+ cells, the expansion of these cells seems to be important for clinical application. Mesenchymal stromal cells (MSCs), playing an important role in HSCs maintenance, were used as feeder layer. Apo...

introduction: human hematopoietic stem cells (hhscs) have been used for transplantation in hematologic failures. because the number of hhscs per cord blood unit is limited, the expansion of these cells is important for clinical application. it has been reported that cytokines and feeder layer provide a perspective to in vitro expansion of hhscs. in this regard, cord blood cd34+ cells expanded a...

Both cloud and grid are computing paradigms that manage large sets of distributed resources, and the scientific community would benefit from their convergence. This paper proposes a novel computing model, cloudgrid, able to achieve full cloud and grid integration. After presenting its three-layer architecture, the security issues involved are analyzed, proposing a solution based on fine-grained...

Silicon (Si) based complementary metal-oxide semiconductor (CMOS) technology has been the driving force of the information-technology revolution. However, scaling of CMOS technology as per Moore's law has reached a serious bottleneck. Among the emerging technologies memristive devices can be promising for both memory as well as computing applications. Hybrid CMOS/memristor circuits with CMOL (C...

This work consists in a numerically evaluation of elastic fields distribution, caused by intrinsic dislocation networks placed at a nanometric trilayers interfaces, in order to estimate their influence on the surface topology during heterostructure operation. The organization of nanostructures is ensured by the knowledge of different elastic fields caused by buried dislocation networks and calc...
