In this paper, An effective and simple numerical method is proposed for solving systems of integral equations using radial basis functions (RBFs). We present an algorithm based on interpolation by radial basis functions including multiquadratics (MQs), using Legendre-Gauss-Lobatto nodes and weights. Also a theorem is proved for convergence of the algorithm. Some numerical examples are presented...

A 71-year-old woman presented with shortness of breath and involuntary head shaking. Physical examination showed nodding of the head with each heart beat (Video 1). Her pulse rate and blood pressure were 40 bpm and 125/55 mm Hg, respectively. ECG revealed complete atrioventricular block with a ventricular rate of 40 and atrial rate of 75 (Fig. 1a). Transthoracic echocardiography displayed moder...

BACKGROUND Biventricular (BiV) and left ventricular (LV) pacing similarly augment systolic function in left bundle-branch block (LBBB)-failing hearts despite different electrical activation. We tested whether electrical synchrony is required to achieve mechanical synchronization and functional benefit from pacing. METHODS AND RESULTS Epicardial mapping, tagged MRI, and hemodynamics were obtai...

Matched-filter is widely used in real time signal processing, especially in Radar Signal Processing. This paper provides a novel structure of digital matched-filter used in tracking radar system. This design applies block-floating-point arithmetic to improve the precision. The whole digital matched-filter is implemented in only one chip of FPGA. This ASIC has two work modes: 512 points pulse co...

BACKGROUND Left ventricular or biventricular pacing/stimulation can acutely improve systolic function in patients with dilated cardiomyopathy (DCM) and intraventricular conduction delay by resynchronizing contraction. Most heart failure therapies directly enhancing systolic function do so while concomitantly increasing myocardial oxygen consumption (MVO(2)). We hypothesized that pacing/stimulat...

BACKGROUND This prospective, randomized, double-blind, clinical study was conducted to compare the effects of 4% articaine with 1:100,000 epinephrine (A100) and 4% articaine with 1:200,000 epinephrine (A200) on the vital signs and onset and duration of anesthesia in an inferior alveolar nerve block (IANB). METHODS In the first appointment, an IANB was performed by injecting A100 or A200 in 1 ...

Steady-state spin path. The tip-up pulse (blue) is tailored to the mean free precession angle ( within each voxel, and there is in general a mismatch between the isochromat spin phase in that voxel and the tip-up phase. (b) Transverse magnetization profile vs. phase mismatch. The observed voxel signal is obtained by integrating the profile over the intra-voxel B0 distribution, which depends on ...
