Adults ( N = 54, 80.78 ± 6.08 years) who reported falling during the previous 12 months participated in a 12-week wobble board training program with internal focus or external (EF) instructions. Verbal manipulation checks were performed after sessions as self-report of attentional foci used. The percentage which participants using an EF (EF SR ) was subsequently calculated. Mean velocity and me...

We present evidence from high resolution optical spectra for the presence of bipolar jets in the bright super soft X-ray source RX J0019.8+2156, the second such discovered case after RX J0513.9-6951. The jets seem to appear and disappear over a time scale of several months. No jet precession is observed. From the velocity separation of the emission lines produced by the jets a lower limit of ∼ ...

Witasse) We simulate space weathering of Phobos’ surface due to both sputtering by solar wind ions (H and He) and planetary protons, and surface material vaporization by micrometeoroids impact. Assuming an Ironrich composition of Phobos’ regolith, ...

Data from 3 recently completed studies were pooled and analyzed to answer the question whether breastfed infants of overweight/obese mothers show accelerated growth. It was shown that these infants gain weight faster than indicated by the WHO standards and that they grow significantly faster than infants of lean mothers. The question whether fast infant growth can be slowed down by lowering the...

DOI: 10.4103/0019‐5154.198054 A 65‐year‐old apparently healthy male presented with an asymptomatic growth over the right thigh, present for the past 1 year. Initially, the lesion was a pea‐sized growth which gradually increased in its dimension and morphology to attain the the present size. (2.5 cm × 3 cm). Cutaneous examination showed a solitary moist firm slightly tender nodule over the later...

A new geometric approach to the a ne geometry of curves in the plane and a ne-invariant curve shortening is presented. We describe methods of approximating the a ne curvature with discrete nite di erence approximations, based on a general theory of approximating di erential invariants of Lie group actions by joint invariants. Applications to computer vision are indicated. y Supported in Part by...

Levison We present a scenario for building the equatorial ridge and de-spinning Iapetus through an impact-generated disk and satellite. This impact puts debris into orbit, forming a ring inside the Roche limit and a satellite outside. This satelli...
