Background: Electronic fetal monitoring was used in many hospitals before labor and during delivery . The objective of this study was to investigate whether the use of fetal monitoring had effect on neonatal outcomes and cesarean section rate. Materials and Methods: A prospective study on monitoring neonatal Apgar and kind of delivery data, from deliveries occurring at Shahid Sadughi hospital i...

Humans are able to judge whether a target is accelerating in many viewing contexts, but it is an open question how the motion pattern per se affects visual acceleration perception. We measured acceleration and deceleration detection using patterns of random dots with horizontal (simpler) or radial motion (more visually complex). The results suggest that we detect acceleration better when viewin...

Background: Conventional echocardiography and tissue Doppler imaging have been highlighted to diagnose diastolic and systolic heart dysfunction. We aimed to compare tissue Doppler imaging with conventional echocardiography to diagnose heart dysfunctions in diabetes mellitus type 1 (DMT1) patients. <s...

Several past studies developed acceleration/deceleration rate models as a function of single explanatory variable. Most them were spot speed with speeds measured at specific locations on curves (usually midpoint the curve) and tangents to determine acceleration deceleration rates. Fewer adopted an estimated value 0.85 m/s2 for both rates while approaching departing curves, respectively. In this...

1. The role of phasic muscle activation in determining the temporal properties of human arm movements was studied. The experiments show that subjects can modulate the triphasic electromyographic (EMG) pattern to produce movements of varied temporal structures. 2. Subjects performed horizontal forearm movements in which they varied movement accelerations and decelerations. All movements were of ...

The Onsager reaction term is one of the most important notions for frustrated random systems. The role of the Onsager reaction term, however, has not been properly elucidated for non-equilibrium random systems with large degrees of freedoms. By analyzing oscillator associative memory models involving two types of diluted couplings, we make clear that the acceleration (deceleration) effect is ca...

Traffic flow on straight roads is the most common traffic phenomenon in urban road traffic networks. In this paper, a realistic cellular automaton (CA) model is proposed to investigate driver behavior on urban straight roads based on our field observations. Two types of driver behavior, free and car-following, are simulated. Free driving behavior is modeled by a novel five-stage speeding model ...

A major West Antarctic ice stream discharges by sudden and brief periods of very rapid motion paced by oceanic tidal oscillations of about 1 meter. Acceleration to speeds greater than 1 meter per hour and deceleration back to a stationary state occur in minutes or less. Slip propagates at approximately 88 meters per second, suggestive of a shear wave traveling within the subglacial till. A mode...
