Background While blood flow in the majority of arteries peaks in systole, the rhythmic squeezing of the coronary arteries and microcirculation as the heart beats results in left anterior descending artery (LAD) flow being diastolicpredominant while for the right coronary artery (RCA), there is approximately equal flow in systole and diastole. These temporal flow patterns can provide important i...

Effect of nonlinear thermal radiation on the unsteady magnetohydrodynamic slip flow of Casson fluid between parallel disks in the presence of thermophoresis and Brownian motion effects are investigated numerically. A similarity transformation is employed to reduce the governing partial differential equations into ordinary differential equations. Further, Runge-Kutta and Newton’s methods are ado...

This model focuses on the behavior of capillary-tissue fluid exchange system when the diameter of the capillary is less than that of red cell. In vivo and in vitro observations indicate that the width of the gap between the red cell and the vessel wall is generally small compared to the radius of the capillary for a single file flow of red cell in narrow vessel, particularly if the vessel diame...

In this paper, we report a theoretical study of transient squeezing flow through thin porous gap driven by an oscillating boundary. The process is governed the viscous, inertial, and Darcy effects. It shows that when depth increases, alternating dominance viscous inertial effects would increase oscillation velocity profiles. existence media effectively stabilizes fluid field. presented herein, ...

We introduce a model of squeezing and noise reduction in the Kerr effect that accounts for noise in all quadratures of the driving field. Consequently we show that Kerr squeezing is much more sensitive to driving noise than squeezing produced by second harmonic generation (SHG). We experimentally demonstrate this sensitivity using a nonlinear system that tunes between strong classical SHG and K...

We present a brief history of experimental studies of quadrature squeezing, a tutorial on the physical origin and theory of squeezing, and our experimental study of squeezing by means of x (2) (second-order) nonlinear waveguides. We recently obtained 28% squeezing in quasi-phase-matched LiTaO3 waveguides, using picosecond pulses. The amount of squeezing appears to be limited primarily by blue-l...
