Introduction: Coronary artery disease (CAD) is the most common type of heart disease, with a mortality rate of 385,000 person per year in the United States. There are two main methods for CAD treatments: angioplasty and bypass surgery. Coronary Artery Bypass Grafting (CABG) is one of the greatest surgical operations of the 20th century and it is presented as most effective and long-term therapi...

the effects of pulsed electric field (pef) on the cell disintegration of sugar beet were studied. field strength (0.5kv/cm to 6kv/cm), pulse number (1 to 100 pulses) and capacity of capacitors (0.5 f to 32 f) were evaluated on degree of cell disintegration and consumed energy in pef treatment. the field conditions of 1 and 2 kv/cm, 8 f with 20 and 10 pulses respectively disintegrated the cel...

During the past decade the application of light pulses in the picosecond time domain has received increasing attention. In these investigations it is of primary interest to know the duration of the ultrashort light pulses. Two methods to measure the pulse duration have found frequent application: The two-photon fluorescence technique, TPF [I] and the streak camera [2]. The autocorrelation patte...

Introduction: The elemental composition of rocks and soils is one of the most fundamental types of information needed to understand geologic contexts and to search for likely locations of biological activity. Nearly all methods for determining elemental composition involve in-situ analysis, requiring time-consuming maneuvering of a rover to acquire the desired sample. By contrast, analyses at s...

Discrete event simulation is a methodology to study the behavior of complex systems. Its drawback is that, in order to get reliable results, simulations have to be usually run over a long stretch of time. This time requirement could decrease through the usage of parallel or distributed computing systems. In this paper we analyze the Time Warp synchronization protocol for parallel discrete event...

We propose a method to broaden the cut-off region of high harmonic generation by optimizing the parameters of two-color laser fields synthesized by an intense 5 fs pulse at 800 nm and a relatively weak, subharmonic pulse at 2400 nm. Simulated Annealing (SA) algorithm is employed to optimize the electric field amplitude, pulse duration of the control pulse, and the time delay between two pulses....
