NMR magnet coils are usually quite long, thick, and tightly wound with thin superconducting wires. The successful vacuum/pressure impregnation of such kind of coils demands the use of epoxy resins with superior properties such as low viscosity, long pot life, and high cracking resistance etc.. In order to find the most appropriate impregnating epoxy resin for the fabrication of high-field NMR m...

We demonstrate “on the fly” electron spin resonance ESR in which the defect generation process in the negative bias temperature instability NBTI can be observed without recovery contamination. Elevated temperature and modest negative gate bias generates ESR spectra due to E center defects. The NBTI generated E center spectrum disappears upon stress condition removal, a result consistent with re...

1. Adenosine and its metabolically stable analogue N-ethyl-carboxamidoadenosine (NECA) enhance histamine release from rat peritoneal mast cells when these are stimulated by calcium-mobilizing agents. NECA and adenosine shift the concentration-response curve of the calcium ionophore A23187 to lower concentrations. 2. The potencies of NECA or adenosine in enhancing A23187-induced histamine releas...

Corner-based design and verification are based on worst-case analysis, thus introducing over-pessimism and large area and power overhead and leading to unnecessary energy consumption. Typical case-based design and verification maximize energy efficiency through design margins reduction and adaptive computation, thus helping achieve sustainable computing. Dynamically adapting to manufacturing, e...

CERN has encouraged the US-LARP collaboration to participate in Phase I of the LHC luminosity upgrade by analyzing the benefits gained by using Nb3Sn technology to replace the functionality of select NbTi magnets that CERN is committed to construct. Early studies have shown that the much higher gradients (shorter magnetic lengths) and temperature margins (quench stability) of Nb3Sn magnets comp...

The effects aging of digital circuits are came into the focused due to observations made with several experiments and researchers has start working towards making changes for the improvements in base paper architecture. The integrated device suffers with NBTI and PBTI due to CMOS semiconductor properties and it affects the working of different logic operations and in the same context here we ha...

In this paper, delay and transient power-supply current (IDDT) testing has been applied for a 90nm VLIW DSP IP core, to demonstrate the IDDT testing an effective alternative of delay testing to detect aging degradation. The test environment for validation, implementing an accelerated test (AT) has been investigated, delay and IDDT measurement data resulting from AT is presented and analysed. It...

The term receptor reserve, first introduced and used in the traditional receptor theory, is an integrative measure of response-inducing ability of the interaction between an agonist and a receptor system (consisting of a receptor and its downstream signaling). The underlying phenomenon, i.e., stimulation of a submaximal fraction of receptors can apparently elicit the maximal effect (in certain ...

The Ion Cyclotron Resonance Accelerator (ICRA) uses a novel geometry which combines the radial confinement and azimuthal acceleration of cyclotrons together with the axial drift used in gyrotrons. Use of a common NbTi superconducting solenoid and an rf driven magnetron structure lead to a simple, lightweight, and compact machine that could be designed for portability. An ICRA designed to accele...

Adenosine (ADO), an endogenous regulator of coronary vascular tone, enhances vasorelaxation in the presence of nucleoside transport inhibitors such as dipyridamole. We tested the hypothesis that coronary smooth muscle (CSM) contains a high-affinity transporter for ADO. ADO-mediated relaxation of isolated large and small porcine coronary artery rings was enhanced 12-fold and 3.4-fold, respective...
