To establish a versatile means for screening and management of nonalcoholic steatohepatitis (NASH), shear wave velocity was measured in 20 normal controls and 138 consecutive nonalcoholic fatty liver disease (NAFLD) cases. Referencing biochemical properties in 679 healthy volunteers, a formula to distinguish NASH suspects was established and validated in another cohort of 138 histologically pro...

Vehicles parked on streets or roads can cause various hazards to people and property when they are swept away by urban floods. It is therefore approproriate to investigate the criterion of vehicle stability for such flood conditions, especially for different scenarios and where the criterion for vehicle stability is usually represented by the incipient velocity for the vehicle. In the current s...

abstract background: infants’ feeding is one of the critical periods in women’s health that can influence their life. the purpose of this study was to investigate the relationship between infants’ feeding patterns and mothers’ physical and psychological dimensions of quality of life. materials and methods: in this cross-sectional study, 189 mothers were selected by convenience sampling (n = 63 ...

We discuss the definition of particle velocity in doubly relativity theories. The general formula relating velocity and fourmomentum of particle is given. ∗supported by KBN grant 2 P03B 134 16

The limiting bubble wall velocity during a first-order electroweak phase transition is of interest in scenarios for electroweak baryogenesis. Khlebnikov has recently proposed an interesting method for computing this velocity based on the fluctuation-dissipation theorem. I demonstrate that at one-loop order this method is identical to simple, earlier techniques for computing the wall velocity ba...

introduction : cerebral autoregulation (ca) and mean cerebral blood flow velocity in males and females are still under controversy. the present study was scheduled to address the effect of sex on these parameters. materials and methods : the present study was interventional and performed on 30 healthy volunteers (15 males aging from 20-30 yrs and mean age of 23.9±3 years old and 15 females agin...

Prestack depth migration provides a powerful tool for velocity analysis in complex media. Both prominent approaches to velocity analysis—depth-focusing analysis and residual-curvature analysis, rely on approximate formulas to update velocity. Generally, these formulas are derived under the assumptions of horizontal reflector, lateral velocity homogeneity, or small offset. Therefore, the convent...

In a variety of applications, most notably microfluidics design, slip-based boundary conditions have been sought to characterize fluid flow over patterned surfaces. We focus on laminar shear flows over surfaces with periodic height fluctuations and/or fluctuating Navier scalar slip properties. We derive a general formula for the ‘effective slip’, which describes equivalent fluid motion at the m...
