Forkhead box P3 (FoxP3)-positive T cells are a specialized T cell subset for immune regulation and tolerance. We investigated the trafficking receptor switches of FoxP3(+) T cells in thymus and secondary lymphoid tissues and the functional consequences of these switches in migration. We found that FoxP3(+) T cells undergo two discrete developmental switches in trafficking receptors to migrate f...

MinD and MinC cooperate to form an efficient inhibitor of Z-ring formation that is spatially regulated by MinE. MinD activates MinC by recruiting it to the membrane and targeting it to a septal component. To better understand this activation, we have isolated loss-of-function mutations in minD and carried out site-directed mutagenesis. Many of these mutations block MinC-MinD interaction; howeve...

Composition, change and complexity have attracted ev- eryone’s attention towards Self-Adaptive systems. These systems, inspired by the human body, are capable of adapting to changes in the inner and outer environment. The main objective of this study is to achieve a more con- venient availability for e-banking services in the payment switch, using self-healing systems and focusing on the failur...

In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the ZETA converter advantages such as, buck-boost capability and input to output DC insulation. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low v...

Objective: Using the safety goggles to protect and treat process of fog, powder or laser injury eyes, reduce noise thus patient's discomfort. At same time, pulse frequency vital signs patients can be detected during treatment improve treatment. Methods: The device is a for dental that monitor pulse, including mirror frame, protective lens mounted on one side frame first elastic band second loca...

[1] Rapid and extensive growth of sea ice cover was suggested to play a major role in the sea ice switch mechanism for the glacial cycles as well as on shorter millennial scales [Gildor and Tziperman, 2000]. This mechanism also predicts a hysteresis between sea ice and land ice, such that land ice grows when sea ice cover is small and withdraws when sea ice cover is more extensive. The switch-l...

the periodic trimming of the long hairs growing at the distal end of the tail -switch trimming- is humane alternative of tail docking. the purpose of this study was to determine the influence of switch trimming on somatic cell count (scc), california mastitis test (cmt) and udder cleanliness of lactating cows in a free-stall dairy farm. in the present study, 219 healthy, pregnant holstein cows ...

Preemptive hardware multitasking is not supported in most reconfigurable systems-on-chip (rSoCs), which severely limits the scope of hardware scheduling techniques on these platforms. While modern field-programmable gate arrays (FPGAs) support dynamic partial reconfiguration of any region at any time, most hardware tasks cannot be preempted at arbitrary points in time, because context saving an...
