Received ; accepted – 2 – ABSTRACT We present a BeppoSAX observation of the X–ray source AX J0851.9−4617.4 that has been proposed as the neutron star associated to the shell like-supernova remnant RX J0852.0−4622. The image at E>5 keV shows the presence of a new source, SAX J0852.0−4615 , not resolved from AX J0851.9−4617.4 in previous observations. The improved positional accuracy obtained for...

The distance-resolved effective interaction between two star polymers in a good solvent is calculated by Molecular Dynamics computer simulations. The results are compared with a pair potential proposed recently by Likos et al. [Phys. Rev. Lett. 1998, 80, 4450] which is exponentially decaying for large distances and crosses over, at the corona diameter of the star, to an ultrasoft logarithmic re...

We describe our recent work in implementing a word-spotting system based on the ANGIE framework and the effects of varying the nature of the sublexical constraints placed upon the wordspotter’s filler model. ANGIE is a framework for modelling speech where the morphological and phonological substructures of words are jointly characterized by a context-free grammar and are represented in a multi-...

rules , and generates the set of all paths in the rule base . Path Hunter found 512 abstract rules in the Blackbox Expert’s rule base , which formed 516 paths . A single path found by Path Hunter is shown in Figure 1 . The square nodes represent abstract rules , the ‘‘round’’ nodes represent predicates , and the directed arcs represent data dependencies between the rules . The logical completio...

The crossing of the Galactic disk by a Globular Cluster could produce star formation due to gravitational focussing or compression of disk material. We report on simulations of the effect on disk material which reveal that the crossing can sometimes cause local gravitational focussing of disk material. We also present the salient points of a little-known paper by Levy (2000), that shows that st...

an extended star is a tree which has only one vertex with degree larger than two. the -center problem in a graph  asks to find a subset  of the vertices of  of cardinality  such that the maximum weighted distances from  to all vertices is minimized. in this paper we consider the -center problem on the unweighted extended stars, and present some properties to find solution.

The sharing economy is spreading rapidly worldwide in a number of industries and markets. The disruptive nature of this phenomenon has drawn mixed responses ranging from active conflict to adoption and assimilation. Yet, in spite of the growing attention to the sharing economy, we still do not know much about it. With the abundant enthusiasm about the benefits that the sharing economy can unlea...

A learning health system (LHS) integrates research done in routine care settings, structured data capture during every encounter, and quality improvement processes to rapidly implement advances in new knowledge, all with active and meaningful patient participation. While disease-specific pediatric LHSs have shown tremendous impact on improved clinical outcomes, a national digital architecture t...
