The regional differentiation of carotid sinus control of arterial pressure-flow relationships was studied in chloralose-anesthetized dogs. Simulatneous pressure-flow measurements were made in the ascending aorta, the celiac artery, the cranial mesenteric artery, the renal artery, and the femoral artery. The carotid sinuses were bilaterally isolated and perfused with pulsatile pressure. The open...

measurement of the stroke volume and its changes over time can be very helpful for diagnosis of dysfunctions in the blood circulatory system and monitoring their treatments. impedance cardiography (icg) is a simple method of measuring the stroke volume based on changes in the instantaneous mean impedanceof the thorax. this method has received much attention in the last two decades because it is...

Dipole antenna is the simplest and widely used antenna in telecommunication applications which consists of two identical conductive metal wires. Dipole antenna performance is dependent on many parameters such as metal conductivity, length, radius of wire, surrounding medium, feeding point and etc. but, In this article, we are studying the effect of length and radius on the performance of these ...

Recent work has demonstrated nanopatterning of gold, using a Focussed Ion Beam, and similarly, nanotemplating gold, for direct protein attachment, useful for alternative sensing techniques. The impedance changes due to myoglobin capture by antimyoglobin immobilised on gold, have been measured, in a 3 electrode electrochemical cell. The impedance changes reach an end-point level after 15-20 minu...

Point-of-care testing (POCT), or bedside testing is defined as medical testing at or near the site of patient care. In order to approach POCT, a miniaturization system consists of microfluidics chip, bio-recognition probes and electrically sensing element for providing enough information on clinical diagnosis. As the result, multidisciplinary researches and integrations are crucial for developi...

Theoretical work on two-sided matching markets has focussed on the stable outcomes that are optimal for one side of the market. An innovative exception is a paper by Rochford, who shows how to identify a nonempty set of interior points of the core of the assignment market first studied by Shapley and Shubik. We strengthen Rochfold’s results, by showing that such a set of fixed points must refle...

Exposure to whole-body vibration is a risk factor for the development of low back pain. In order to develop a fuller understanding of the response of the seated person to vibration, experiments have been conducted in the laboratory investigating the biomechanics of the seated person. Some of these methods are based on the driving force and acceleration at the seat and are reported in the litera...

A novel diagnosis method has been developed based on transistor operating point analysis. The method is worked by the way of fault logic propagation trace based on voltage value and the way of operation time setting of each gate circuit. The former way is to detect penetration current net result from fault, replace the net with impedance net, calculate voltage value of each node of the impedanc...

The direct point by point swept solution of the discretised Helmholtz equation over a broad frequency range can become computationally expensive for large systems when fine frequency increments are required. Approaches involving reduced-order models using Padéor waveform-based methods such as the well conditioned asymptotic waveform evaluation (WCAWE) can be used to significantly reduce this an...
