Aperture averaged scintillation of four petal Gaussian beam is studied in this article. Split step propagation approach which used wave applications selected to model atmospheric turbulence. Results are plotted two types. First type the analysis aperture versus distance for constant receiver aperture. Second ones involve performance applying averaging at distance. All results compared with Gaus...

OBJECTIVES This study was designed to characterize the organization of ventricular fibrillation (VF) on the endocardium of humans. BACKGROUND Most proposed mechanisms for the maintenance of VF postulate the propagation of a number of activation wave fronts that reenter to maintain the arrhythmia. We tested the hypothesis that, in patients undergoing internal cardioverter-defibrillator implant...

the formation constants of the species formed in the systems h+ + mo(vi) + histidine and h+ +histidine have been determined at different aqueous solutions of methanol (0 - 45 % v/v) at 25 °c andconstant ionic strength (0.1 mol dm-3 sodium perchlorate), using a combination of spectrophotometricand potentiometric techniques. the composition of the complex species was determined by thecontinuous v...

avo theory was introduced around 20 years ago. in recent years, this technique was become to a major tool in hydrocarbon sources exploration. by the help of this method with the suitable understanding from underground layers and knowing how to use this technology, quantitative specifications of reservoir can be recognized. avo analysis is a seismic technique that by using of pre-stack data, est...

In this paper, the Lakshmanan-Porsezian-Daniel (LPD) equation is studied. New analytical rational solitons to LPD are presented by an ansatz method. Wave solutions of three types, such as parabolic, trigonometric and hyperbolic function have been retrieved. All plotted in 3D enhance understanding their physical characteristics. These simulations, which represent behavior resulting hyperbolic, p...

Experimental values of N/Z equilibration were calculated by the method developed by A. Keksis [1]. The isobaric yield ratios for the A=3,6,7,11,14,16 isobars were calculated from reactions of Ca beams on Sn targets. These isobar yield ratios were then plotted individually versus the N/Z of the quasi-projectile (QP) for the four systems. The (N/Z)QP was assumed to be a straight mixing between th...

seismic waves when crossing the earth in heterogeneous and anisotropic environments, having interaction. recognizing the impact of these factors on the seismograms help us to find out more information about interior of the earth. coda waves are the main reason for the random heterogeneities in earth. local earthquakes in the northeast region of iran with epicentral distance less than 200 km is ...

In this study, we will introduce the modified (G'/G2)-expansion method to explore some of exact traveling wave solutions nonlinear partial differential equations namely, Phi-4 equation, Joseph-Egri (TRLW) and Calogro-Degasperis (CD) equation. As a result, have obtained for expressed in terms trigonometric, hyperbolic rational functions. Moreover, selected are plotted using specific values param...

Figure 3. Left: Fitted RRFs for the average timecourse of 9 subjects (color) compared with the RRF in response to a single deep breath [1] (black), plotted as %BOLD versus scan volume. Center: Manual alteration of the a2 parameter of the original RRF [1] (2a2 and 3a2, black lines) suggests this parameter explains much of the difference in response dynamics. Right: Boxplots of fitted parameter v...
