The main contribution of this short note is to provide improved bounds on the approximability of constructing terminal Steiner trees in arbitrary undirected graphs. Technically speaking, our results are obtained by relating this computational task to that of computing group Steiner trees. As a secondary objective, we make a concentrated effort to distinguish between the factor by which construc...

OBJECTIVE Spontaneous mediastinal emphysema is uncommon. Its cause has not been determined precisely, but the entity is usually associated with suddenly raised alveolar pressure. METHODS Between 1980 and 2001, 114 patients with mediastinal emphysema of various causes were hospitalized in the Wolfson Medical Center. In 22 of these patients (19.3%) the emphysema occurred without an obvious prec...

OBJECTIVE During July-August 2014, the military operation "Protective Edge" presented Israel with a threat of missile attacks. We aimed to investigate the influence of the "Protective Edge" operation on the rate of pregnancy complications among the population exposed to missile attacks, compared to the population not exposed. STUDY DESIGN This was a retrospective study. Pregnancy outcomes wer...

Moving objects databases (MODs) provide the framework for the efficient storage and retrieval of the changing position of continuously moving objects. This includes the current and past locations of moving objects and the support of spatial queries that refer to historical location information and future projections as well. Nowadays, new spatiotemporal applications that require tracking and re...

Convex Polyhedra S. A. Cameron R. K. Culley McDonnell Douglas Research Laboratories Arti cial Intelligence Technology Group St. Louis, MO, USA 63166 Abstract Given two objects we de ne the minimal translational distance (MTD) between them to be the length of the shortest relative translation that results in the objects being in contact. MTD is equivalent to the distance between two objects if t...

MOTIVATION Atomic resolution modeling of large multimolecular assemblies is a key task in Structural Cell Biology. Experimental techniques can provide atomic resolution structures of single proteins and small complexes, or low resolution data of large multimolecular complexes. RESULTS We present a novel integrative computational modeling method, which integrates both low and high resolution e...
