However, the existing self-healing strategies of embryonics circuits mainly focus on permanent faults inside the modules of cells such as the function module and the configuration register, while little attention is paid to transient faults. From the point of view of obtaining high efficiency of hardware utilization, it would be a huge waste of hardware resources by permanent elimination when a cell only suffers a transient fault which can be repaired by a configuration mechanism. A new self-healing strategy, the Fault-Cell Reutilization Self-healing Strategy(FCRSS) which presents a method for reusing transient fault cells, is proposed in this paper. The circuit structures of all the modules in the cells are described in detail. In the new strategy, two processes of elimination and reconfiguration are combined. Within the process of fault-cell elimination, cells with transient faults in the embryonics circuit array could be reused simultaneously to replace the functions of the cells on their left side in the same row. Therefore, transient fault-cells in a transparent state can be reconfigured to realize the fault-cell reutilization. Finally,a circuit simulation, resource consumption, a reliability analysis and a detailed normalization analysis are presented. The FCRSS can improve the hardware utilization rate and system reliability at the expense of a small amount of hardware resources and reconfiguration time. Following the conclusion, the method of determining the optimal self-healing strategy is presented according to the environmental conditions.展开更多

[Method] The starch residue of Shangshu 19 from four different processing sites was used as the test material, and the contents of main nutritional ingredients and moisture in the sweet potato starch residue were determined. [Result] In the sweet potato starch residue （calculated by fresh weight）, the average contents of moisture, starch, fat, protein, Zn, Fe, Se and Ca were 83.75%, 101.15 g/kg, 0255%, 0.497 3%, 11.18 mg/g, 1 219.00 mg/kg, 0.032 3 mg/kg and 6 460.00 mg/kg, respectively, but Vc, VA and chlorogenic acid were not detected. According to the characteristics of high starch content and abundant nutritional ingredients, the sweet potato starch residue can be used for producing edible alcohol and dietary fiber health food. [Coaclusio,] This study will provide certain reference for fully development and utilization of sweet potato starch residue.展开更多

To clarify the role of TdT-enzyme for this function of progenitor lymphocytes, their extracellular media with its components included by living cells analyzed <em>in vitro</em> before and after<em> in vivo</em> irradiation of donor rats. The nucleoid with DNase-sensitive (free) DNA and TdT activity discovered in extracellular media conditioned preliminary by spontaneous apoptotic death of a minor part of the thymocyte’s suspension <em>in vitro</em>. The penetration of labeled products of non-template synthesis with free DNA’ primers from media into cells by pinocytosis confirmed by exogenous polymeric DNA marked artificially. The DNA penetration into cells follows an increase of the cell’s viability and acceleration of spontaneous intracellular DNA-synthesis controlled with labeled thymidine uptake. Both phenomena are typical for either the lowest initial concentration of intact cells or their preliminary irradiation <em>in vivo</em>. The data point to possible involvement of apoptotic decay of TdT<sup>+</sup> cells in the reutilization of the extracellular DNA fragments for reparation/regeneration of surrounding living cells.展开更多
