A method for reducing hardware expenses in compositional microprogram control unit and CPLD chips is proposed. This method is based on the use of pseudoequivalent operational linear chains, wide fan-in of PAL macrocells, and existence of free outputs of embedded memory block in CPLD chips. An example of applying the method is given. It is shown that the method reduces hardware expenses to 30%. 相似文献

Obese (Lepr(fa)/Lepr(fa)) Zucker rats have a missense mutation in the leptin receptor gene. One amino acid substitution in the extracellular domain common to all known leptin receptor proteins results from this mutation. Obese Zucker rats are unable to respond behaviorally to leptin which is peripherally administered. However, conflicting reports exist on whether obese Zucker rats can respond to centrally administered leptin. The purpose of this study was to determine whether obese Zucker rats responded behaviorally and metabolically to intracerebroventricularly (i.c.v.) administered leptin and to compare the responses of lean and obese Zucker rats. We found that both lean and obese Zucker rats had similar body weight and food intake responses when administered a single i.c.v. leptin injection in a range of doses (1.25, 2.5, 5, and 10 microg), as well as daily i.c.v. administered leptin for five consecutive days. Both single and daily leptin administration also decreased respiratory quotient (RQ) similarly in lean and obese Zucker rats, indicating mobilization of fat as an energy source for leptin-treated rats. After withdrawal of daily leptin treatment, lean and obese Zucker rats exhibited different recovery responses. It is concluded that obese Zucker rats can respond to exogenous leptin when leptin is delivered into the brain ventricles. 相似文献

Improved hemodynamics and blood flow have been reported in patients with IABPs who experience cardiopulmonary arrest and require CPR. The following research questions, however, remain unanswered: Is there a more effective method of using IABP to prevent cardiac arrest and the need for CPR? Is the timing of balloon inflation and deflation the same for patients undergoing CPR as it is for patients who do not require CPR? Would earlier or later inflation or deflation further enhance cerebral or systemic blood flow? What are the most effective ways for healthcare staff to maintain competency skills in CPR in patients with IABPs? 相似文献

The independent and cumulative measured yields of residual products in thin lead and bismuth targets irradiated with 0.04-2.6 GeV protons are compared with results by the LAHET, CEM03, LAQGSM03, INCL+ABLA, CASCADE and YIELDX codes, in order to evaluate the predictive power of the codes in this energy region. We found that the predictive power of the tested codes is different but is satisfactory for most of the nuclides in the spallation region, though none of the codes agree well with the data in the whole-mass region of product nuclides and all should be improved further. On the whole, the predictive power of all codes for the data in the fission and fragmentation product regions and, especially, at the borders between spallation and fission and between fission and fragmentation regions is much worse than in the spallation region; therefore, development of better evaporation/fission/fragmentation models is of first priority. 相似文献

The paper addresses the application of a sessile drop method for the study of surface quality of thermoplastic polymer materials—polystyrene
and polymethyl methacrylate—upon edge cutting machining. A correlation has been found between the thermal-physical state of
their surface layer and the surface wettability. The method is demonstrated to be suitable for the assessment of thermodynamic
stability of the surface layer structure of polymers during finishing operations in the manufacture of optical products. 相似文献
