background  short stature is a manifestation of a wide variety of conditions that some of which may be amenable to timely treatment and a suboptimal growth rate may be an early marker pointing to the cause of growth retardation. this study was conducted to evaluate the diagnostic utility of growth rate in differential diagnosis of children with short stature. materials and methods all children ...

To meet the asymmetric (sub micro-radian towards Earth, tens of micro-radians elsewhere) pointingrequirements of the RIP mission, a hybrid approach to optical attitude determination is suggested. Aredundant pair of Coarse Star Scanners (CSS) have line-of-sight normal to the spin axis. If attitude updaterates are not too high, a straightforward extension of presently available techno...

BACKGROUND Asymmetry in animal bodies and behavior has evolved several times, but our knowledge of their linkage is limited. Tanganyikan scale-eating cichlids have well-known antisymmetry in their bodies and behavior; individuals open their mouths leftward (righty) or rightward (lefty), and righties always attack the right flank of the prey, whereas lefties attack the left. This study analyzed ...

Abstract The preliminary impulse of the sudden commencement is simply explained by generation compressional wave due to compression dayside magnetopause and mode conversion from Alfvén in magnetosphere. However, this simple model cannot explain a time delay peak displacement longer duration higher latitudes pre-noon post-noon sectors polar region. Based on global magnetohydrodynamic simulation ...

Computing accurate approximations to the perimeter of an ellipse is a favourite problem of mathematicians, attracting luminaries such as Ramanujan [1, 2, 3]. As is well known, the perimeter, , of an ellipse with semimajor axis a and semiminor axis b can be expressed exactly as a complete elliptic integral of the second kind, which can also be written as a Gaussian hypergeometric function, (1) ...

The present study makes two contributions to the literature on tactile feedback. First, it investigates the effect of tactile feedback in isometric rate control devices. The use of tactile feedback in this type of device has not been systematically investigated. An isometric joystick, such as the IBM TrackpointTM in-keyboard pointing device does not perceptibly move and is operated by force. Ca...
