The adenosine uptake site has been localized in rat brain by an in vitro light microscopic autoradiographic method, using [3H]nitrobenzylthioinosine ( [3H]NBI) as the probe. The binding characteristics of [3H]NBI on slide-mounted sections are comparable to those seen in studies performed on brain homogenates. A very high density of uptake sites occurs in the nucleus tractus solitarius, in the s...

Abstract We focuse on issues related to degradation of FPGAs which has become dominant due to scaling and quantitatively estimate the degradation of FPGAs by NBTI. We map ring oscillators on the Cyclone II FPGAs and measure the variation of oscillation frequency. In the result, the variation of oscillation frequency is 5.97%. As for degradation of FPGAs, we measure the variation of oscillation ...

According to the requirement of the development of superconducting magnets, the research and production of superconducting materials are much interested in many laboratories in China. This article will review the development of superconducting materials in the past ten years in China, and the present situations, mainly in the field of practical materials, Such as NbTi, Nb3Sn, V3Ga and some othe...

While the defects constituting the recoverable component R of NBTI have been very well analyzed recently, the slower defects forming the more “permanent” component P are much less understood. Using a pragmatic definition for P, we study the evolution of P at elevated temperatures in the range 200◦C to 350◦C to accelerate these very slow processes. We demonstrate for the first time that P not on...

The commercial specification of superconducting NbTi and Nb,Sn composite wires is normally given by a few numbers : I,(p,B,T), n, RRR, wire and filament diameter and twist length. To some extent their values cannot be chosen independently, nor do they guarantee proper operation of the system in all aspects, for instance fields in dipoles for accelerators. For Nb,Sn composites, depending on the ...
