It is generally acknowledged that CMEs, especially the faster ones, must deceleration somewhere between the high corona and interplanetary medium. However, the detailed characteristics and spatial region over which this deceleration occurs is still largely unknown. Simultaneous radio and white-light observations can provide information on the speed profiles of the CME or CME/shock in the high c...

In this paper we consider the relation between the volume deceleration parameter obtained within the Buchert averaging scheme and the deceleration parameter derived from supernova observation. This work was motivated by recent findings that showed that there are models which despite having Λ = 0 have volume deceleration parameter qvol < 0. This opens the possibility that back-reaction and avera...

PURPOSE When saccade amplitude is systematically inadequate relative to the desired target position, the saccadic system adaptively modifies the amplitude of subsequent saccades so as to recover precise targeting capabilities. The effect of saccadic adaptation on saccade metrics (amplitude, direction) is well documented, but the effect on dynamics (velocity, duration, acceleration, deceleration...

The variable threshold(VT), which detects the speech rate deceleration, is proposed. The VT varies dynamically depending upon the duration of previous mora in the utterance. The VT should not change rapidly because listener cannot perceive small variations of mora duration. Thus, a set of functions with time constants which decide response speed of the VT is introduced. We apply the VT to six s...

Transient FHR reduction (deceleration) was classified to U-shape variable one and V-shape periodic one, which is further divided into early deceleration (ED) and late deceleration (LD), of which lag time to uterine contraction is 20 or rmore seconds (Figure 1). LD is placental insufficiency and its outcome was ominous by Hon [1]. CaldeyroBarcia Type I dip was ED and Type 2 was LD [2]. Controver...

in recent research on modelling road collisions very little attention has been paid  to rear-end chain reaction collisions, which is characterized by more than two vehicles involved in a collision at the same time. the core aim of the present research is to develop a methodology to estimate such potential collision probabilities based on a proactive perspective, where deceleration rate to avoid...

Preparatory heart rate deceleration occurs in tasks with an external focus of attention and is often assumed to facilitate balance performance. However, its effects upon sport-related complex balance movements have not been studied. Heart rate patterns during the preparation period of an acrobatic element (flic-flac) on the balance beam were studied in 14 female gymnasts (M age 13.2 years). A s...
