We derive the fractional master equation with space-dependent anomalous exponent. We analyze the asymptotic behavior of the corresponding lattice model both analytically and by Monte Carlo simulation. We show that the subdiffusive fractional equations with constant anomalous exponent μ in a bounded domain [0,L] are not structurally stable with respect to the nonhomogeneous variations of paramet...

The SWAN approach, presented in this paper, addresses the challenging task of developing Semantic Web Applications, i.e., Web applications that fully and effectively exploit and serve the Semantic Web as their operational environment. It is based on the support of two types of models, semantic domain models and conceptual user interface models, as well as on flexible model mappings. The SWAN fr...

Streptococcus sanguinis, a member of the commensal mitis group of streptococci, is a primary colonizer of the tooth surface, and has been implicated in infectious complications including bacteremia and infective endocarditis. During disease progression, S. sanguinis may utilize various cell surface molecules to evade the host immune system to survive in blood. In the present study, we discovere...

There are three basic objectives to this program: (1) to develop a forward prediction capability for the expected value of the SAR-image spectrum, with the SWAN wave-spectrum prediction as input; (2) to develop methods to bring the SWAN-based SAR-spectrum prediction into agreement with satellite-based SAR observations by adjusting the SWAN model inputs; and (3) to validate the improvement in th...

We present SWAN, a statistical framework for robust detection of genomic structural variants in next-generation sequencing data and an analysis of mid-range size insertion and deletions (<10 Kb) for whole genome analysis and DNA mixtures. To identify these mid-range size events, SWAN collectively uses information from read-pair, read-depth and one end mapped reads through statistical likelihood...

INTRODUCTION Most behavior checklists for attention problems or attention deficit/hyperactivity disorder (ADHD) such as the Child Behavior Checklist (CBCL) have a narrow range of scores, focusing on the extent to which problems are present. It has been proposed that measuring attention on a continuum, from positive attention skills to attention problems, will add value to our understanding of A...

Swan is a data structure visualization system. It allows users to visualize the data structures and execution process of a C/C++ program. Swan views a data structure as a graph or collection of graphs. By “graph” we mean general directed and undirected graphs and special cases such as trees, lists and arrays. As a part of Virginia Tech’s NSF Educational Infrastructure Grant, Swan will be used i...

Failure to withdraw a catheter is related primarily to catheter entrapment or knotting. Placement of a Swan-Ganz catheter is associated with various complications, one of which is entrapment. Entrapment of a Swan-Ganz catheter in the heart, vena cava, or pulmonary artery is a very rare and serious complication that may lead to life-threatening complications if not treated appropriately. Most re...
