In epithelial cells, myosin-II-dependent forces regulate many aspects of animal morphogenesis, such as apical constriction, cell intercalation, cell sorting, and the formation and maintenance of the adherens junction. These forces are mainly generated by the circumferential actomyosin belt, which is composed of F-actin-myosin II bundles located along apical cell-cell junctions. Although several...

30 Children show precocious ability in the learning of languages; is this the case with motor 31 learning? We used split-belt walking to probe motor adaptation (a form of motor 32 learning) in children. Data from 27 children (aged 8-36 months) were compared with 33 that from 10 adults. Children walked with the treadmill belts at the same speed (tied34 belt), followed by walking with the belts m...

[Purpose] The purpose of this study was to investigate the effects of a pelvic belt on the activities of trunk and lower extremity muscles in normal adults. [Subjects and Methods] The subjects were 20 normal individuals without a history of orthopedic problems. The pelvic compression belt (The Com-Pressor, OPTP, Minneapolis, MN, USA) was an adjustable body belt with four elastic compression ban...

On July 9, 1962, at 0900 UT (Universal Time) a nuclear device of 1.4-megatons yield was detonated at 400 km above Johnston Island in the Pacific Ocean. Since the explosion took place in the trapping region of the magnetosphere, an artificial radiation belt of considerable intensity was produced. The possible sources of the radiation belt were: (I ) beta-decay electrons from the fission fragment...

Context. The mysterious solar system object 133P/(7968) Elst-Pizarro is dynamically asteroidal, yet displays recurrent comet-like dust emission. Two scenarios were hypothesized to explain this unusual behavior: (1) 133P is a classical comet from the outer solar system that has evolved onto a main-belt orbit, or (2) 133P is a dynamically ordinary main-belt asteroid on which subsurface ice has re...

with the introduction of the use of seatbelts in cars, mortality following motor vehicle crashes has decreased significantly. however, two patterns of injuries, the ‘seatbelt sign’ and ‘seatbelt syndrome’ have emerged. injuries may consist of traumatic abdominal wall disruption. we present two cases of severe abdominal wall disruption caused by a seatbelt injury and treated with primary repair....

We discuss the structure of the Kuiper belt as it can be inferred from the first decade of observations. In particular, we focus on its most intriguing properties – the mass deficit, inclination distribution, the apparent existence of an outer edge and of a correlation among inclinations, colours and sizes – which clearly show that the belt has lost its pristine structure of a dynamically cold ...

We describe calculations of the evolution of an ensemble of small planetesimals in the outer solar system. In a solar nebula with a mass of several times the Minimum Mass Solar Nebula, objects with radii of 100–1000 km can form on timescales of 10–100 Myr. Model luminosity functions derived from these calculations agree with current observations of bodies beyond the orbit of Neptune (Kuiper Bel...

We present visible and near-infrared reflectance spectra and interpreted surface mineralogy for asteroid 10537 (1991 RY16). The spectrum of this object is without precedent amongst the Main Belt asteroids. A unique absorption band centered at 0.63 microns could be attributed to one of several mineralogies. Pronounced 1and 2-micron absorption bands suggest that the composition of 10537

The US Corn Belt supports agroecosystems that flourish in a temperate climate regime that could see significant changes in the next few decades. Because Wisconsin is situated on the northern, cooler fringes of this region, it may be the beneficiary of a warmer climate that could help support higher corn and soybean yields. Here we show that trends in precipitation and temperature during the gro...
