– We propose a design flow for Globally Asynchronous Locally Synchronous systems, which can be used by designers without prior knowledge of asynchronous circuits. The design flow uses conventional synchronous design tools and we have developed a tool to generate and handle the asynchronous circuits in the flow. The design flow starts with high-level model of the system behavior and proceeds dow...

0.1 The Model Consider material flowing among n compartments labeled 1, 2, · · · , n. Assume to begin that no material flows into any compartment from the external environment but that material can flow out of a compartment to the external environment and be lost. Material may flow between compartments. In Pharmacokinetics, the material is a drug, administered to the body, say orally, and the c...

• A number of new technics involving external detection of radioactivity in the blood stream or in tissues have been proposed as means for determining the rate, volume and pathway of blood flow in the intact subject. By virtue of their dependence on indirect, external measurement of indicator (isotope) activity in the body as opposed to direct measurement, these technics have been categorized a...

The blood flow may be diverted from the external to the internal carotid artery via the carotid bulb in the absence of flow in the common carotid artery. We aimed to investigate the prevalence, hemodynamics, and clinical features of this condition. Reviewing the records of color duplex ultrasonographic examinations, we found carotid steal in 12 carotid arteries of 10 patients. In three patients...

The physics of a locked magnetic island chain maintained in the pedestal of an H-mode tokamak plasma by a static, externally generated, multi-harmonic, helical magnetic perturbation is investigated. The non-resonant harmonics of the external perturbation are assumed to give rise to significant toroidal flow damping in the pedestal, in addition to the naturally occurring poloidal flow damping. F...

Air-Conditioning (AC) systems are responsible for a considerable portion of the energy consumption in buildings located in high cooling load requiring regions of Iran. In addition, the heat flow through the buildingschr('39') external walls plays a major role in cooling load estimations for the countrychr('39')s hot regions. Therefore, application of insulation materials in external walls has g...

The transport phenomena of Lennard-Jones molecules through a structural bottleneck driven by an external force are investigated by molecular dynamics simulations. We observe two distinct molecular flow regimes distinguished by a critical external force Fc and find scaling behaviors between external forces and flow rates. Below the threshold Fc, molecules are essentially stuck in the bottleneck ...

BACKGROUND Arteriogenesis (collateral artery growth) is nature's most efficient rescue mechanism to overcome the fatal consequences of arterial occlusion or stenosis. The goal of this trial was to investigate the effect of external counterpulsation (ECP) on coronary collateral artery growth. MATERIALS AND METHODS A total of 23 patients (age 61 +/- 2.5 years) with stable coronary artery diseas...
