We investigate the computational performance of a cutting-plane algorithm for the problem of determining a maximal subclique in an edge-weighted complete graph. Our numerical results are contrasted with reports on closely related problems for which cutting-plane approaches perform well in instances of modera te size. Somewhat surprisingly, we find that our approach already in the case of n = 15...

Widespread application of thermoelectric devices for waste heat recovery requires low-cost high-performance materials. The currently available n-type thermoelectric materials are limited either by their low efficiencies or by being based on expensive, scarce or toxic elements. Here we report a low-cost n-type material, Te-doped Mg3Sb1.5Bi0.5, that exhibits a very high figure of merit zT ranging...

Design of the Alcator C-Mod Thomson Scattering (TS) diagnostic is discussed and the results of the measurements are presented. The TS system has 6 spatial channels with observation volumes evenly distributed between the midplane and the edge of the plasma. Each channel is capable of measuring the electron density in the range Ne = 5x 1019 m-3-5x 1021 m-3 and temperature from Te = 200 eV-10 keV....

Monolithic lasers on Si are ideal for high-volume and large-scale electronic-photonic integration. Ge is an interesting candidate owing to its pseudodirect gap properties and compatibility with Si complementary metal oxide semiconductor technology. Recently we have demonstrated room-temperature photoluminescence, electroluminescence, and optical gain from the direct gap transition of band-engin...

in the present paper, resonant frequencies and modes of a three-atom photonic molecule and a photonic crystal placed within a cavity are numerically calculated. first, governing formulation in transverse electric field mode (te) is obtained using maxwell equations. then, an algorithm based on a finite difference scheme and matrix algebra is presented. the algorithm is then implemented in a comp...

background: transient elastography (te) is a new modality for the diagnosis of liver fibrosis caused by various etiologies. this study was conducted to determine the accuracy of te in detecting the different stages of liver fibrosis in non-alcoholic fatty liver disease (nafld) patients. methods: medline/pubmed, embase, ovid, cochrane library, american college of physicians (acp) journal club, g...

This paper presents a novel approach for tracking feature points in video sequences. In this method, the image intensity is represented by a 3D deformable surface model. Tracking is performed by exploiting a by−product of explicit surface deformation governing equations. The proposed method was compared with the well known KLT tracking algorithm, in terms of tracking accuracy and robustness. Th...

We report on the final results of a series of experiments on double decay of Te carried out with an array of twenty cryogenic detectors. The set-up is made with crystals of TeO2 with a total mass of 6.8 kg, the largest operating one for a cryogenic experiment. Four crystals are made with isotopically enriched materials: two in Te and two others in Te . The remaining ones are made with natural t...
