Introduction: The H spectra of certain tumor cells, in vivo tumors and biopsies, show an intense resonance in the 1.26-1.30 ppm area that has been usually assigned to NMR visible mobile lipids (MLs) . The presence of large ML signal seems to correlate with necrotic areas in the tumors 3 and the non-invasive detection of necrosis would suggest a high grade of malignancy in untreated tumors or co...

We consider the problem of static transmissionpower assignment for lifetime maximization of a wireless sensor network with stationary nodes operating in a datagathering scenario. Using a graph-theoretic approach, we propose two distributed algorithms, MLS and BSPAN, that construct spanning trees with minimum maximum (minmax) edge cost. MLS is based on computation of minmaxcost paths from a refe...

numerical solutions obtained by the meshless local petrov–galerkin (mlpg) method are presented for two-dimensional steady-state heat conduction problems. the mlpg method is a truly meshless approach, and neither the nodal connectivity nor the background mesh is required for solving the initial-boundary-value problem. the penalty method is adopted to efficiently enforce the essential boundary co...

The objective of this study was to identify the differences in histopathological distribution and clinical features of mediastinal lesions (MLs) across the age spectrum in Chinese series of patients and to compare with the available literature. A total of 409 cases of MLs, including 137 pediatric and 272 adult patients from a single institution, was reviewed and categorized into groups accordin...

Sharp features in manufactured and designed objects require particular attention when reconstructing surfaces from unorganized scan point sets using moving least squares (MLS) fitting. It’s an inherent property of MLS fitting that sharp features are smoothed out. Instead of searching for appropriate new fitting functions our approach computes a modified local point neighborhood so that a standa...

Two-way group voice communications, otherwise known as teleconferencing are common in commercial and defense networks. One of the main features of military teleconferences is the need to provide means to enforce the Multilevel Security (MLS) model. In this paper we propose an architecture and protocols facilitating MLS conferences over Public Switched Telephone Network (PSTN). We develop protoc...

This article presents an extension to a Multi-Level Secure (MLS) data model that requires the classification of data and users into multiple security levels. In MLS systems, cover stories allow information provided to users at lower security levels to differ from information provided to users at higher security levels. Previous versions of the MLS model did not permit cover stories for key attr...

With sensors and mobile devices becoming ubiquitous, situation monitoring applications are becoming a reality. Data Stream Management Systems (DSMSs) have been proposed to address the data processing needs of such applications that require collection of high-speed data, computing results on-the-fly, and taking actions in real-time. Although a lot of work appears in the area of DSMS, not much ha...

This paper examines protoryping as a rcscarch tool for studying multilcvcl secure databases (MLS/DBMS). The paper proposes that an MLS/DSMS design can be quickly prototypcd in Prolog. The prototype is then used as a research tool to expcritnent with the policies and models of the MLVDBMS. To illustrate the principle, we built a Prolog prototype based on the dell and LaPadula model. This prototy...
