The covering radius of a code is the least r such that the set of balls of radius r around codewords covers the entire ambient space. We introduce a generalization of the notion of covering radius. The m-covering radius of a code is the least radius such that the set of balls of the radius covers all m-tuples of elements in the ambient space. We investigate basic properties of m-covering radii....

A simple argument concerning bremsstrahlung shows how the presence of many %ofV particles increases the radius of a system. This suggests there is a natural basis for a growth of a particle’s effective radius at high energy in terms of the angular momentum fluctuations of a system containing increasingly larger numbers of particles. A formula which results for the radius in terms of the multipl...

Since 1996 a monitoring campaign of the Galactic Bulge region has been performed by the BeppoSAX Wide Field Cameras in the 2–28 keV band. This allowed accurate and unbiased studies of classes of objects. In particular the type-I X-ray bursters, whose distribution is concentrated in the monitored sky region, have been investigated. High luminos-ity radius-expansion bursts have been observed from...

We present here an analysis based on the Weyl tensor of the Lemaˆıtre-Schwarzschild problem of finding the equilibrium conditions of an anisotrop-ically sustained spherical body (with thus different radial and tangential pressure) under its relativistic gravitational field. An overview of the problem is presented as well as a justification of the unbounded surface redshift when the radial press...

Few studies on the anatomy of the radial epiphysis have been published in the past 10 years. However, with the availability of new intra- and extra-medullary implants and the recent rash of avoidable iatrogenic injuries, now is the time for a more detailed description of the metaphyseal-epiphyseal regions in the distal radius. Published studies on distal radius anatomy in recent years have focu...

BACKGROUND Microscopic colitis presents with similar symptoms to classic inflammatory bowel diseases. Osteoporosis is a common complication of Crohn's disease but there are no data concerning bone metabolism in microscopic colitis. AIMS The aim of the present study was to evaluate bone density and metabolism in patients with microscopic colitis. METHODS Fourteen patients microscopic colitis...

+Wagner, D W; Lindsey, D P; Beaupre, G S Bone & Joint Center of Excellence, VA Palo Alto Health Care System, Palo Alto, CA 94304 [email protected] INTRODUCTION: The degree of mineralization of bone (DMB) is a metric that has been used to non-destructively quantify the distribution of mineral density using micro-computed tomography (microCT). Small increases in the average DMB value hav...

OBJECTIVE A site-specific bone loading index was developed to predict post-menarcheal arm bone mass, geometry, areal density and non-bone lean mass using organized activity records. METHODS Two cohorts of post-menarcheal girls (A= 55, B= 48) met analysis inclusion criteria: (1) Whole body and non-dominant radius DXA scans +1.0 to +2.6 years post-menarche; (2) detailed, organized activity reco...

Over the years, management of complex distal radius fractures by closed means has often failed leading to late collapse. We have chosen the principle of ligamentotaxis using external fixation and bone grafting in this study to prevent late complications. Eighty one patients with complex distal radius fractures belonging to Type IV A, IV B, IV C of Universal classification were treated with an A...
