The single-flavour quark condensate 〈0 |qq| 0〉 is a fundamental parameter of χPT , determining the relative size of mass and momentum terms in the expansion. Since it can not be predicted theoretically, its value must be determined experimentally, e.g. by measuring the ππ scattering lengths, whose values are predicted very precisely within the framework of χPT , assuming a big quark condensate ...

background and aims. anticariogenic effects of different mouthrinses have been shown previously. in this in vitro study the anticariogenic effects of polyphenol extract of green tea with 0.05% fluoride, 0.2% chlorhexidine and fluoride-chlorhexidine were compared. materials and methods. this in vitro study was performed on 50 maxillary premolars in 5 groups: 1) normal saline; 2) a 10% solution o...

The automata-theoretic approach to verification of LTL relies on an algorithm for finding accepting cycles in the product of the system and a Büchi automaton for the negation of the formula. Explicit-state model checkers typically construct the product space “on the fly” and explore the states using depthfirst search. We survey algorithms proposed for this purpose and propose two improved algor...

The increasingly available Graphics Processing Units (GPU) hardware and the emerging General Purpose computing on GPU (GPGPU) technologies provide an attractive solution to high-performance geospatial computing. In this study, we have proposed a parallel primitive based approach to quadtree construction by transforming a multidimensional geospatial computing problem into chaining a set of gener...

PURPOSE The purpose of the present study was to evaluate the effect of root planing on the reduction of probing pocket depth and the gain of clinical attachment depending on the pattern of bone resorption (vertical versus horizontal bone loss) in the interproximal aspect of premolar teeth that showed an initial probing pocket depth of 4-6 mm. METHODS In this study, we analyzed 68 teeth (15 fr...

In this paper we present a novel approach for interactive rendering of virtual views from real image sequences. Combining the concepts of light fields, depth-compensated image warping and view dependent texture mapping, this plenoptic modeling approach can handle large and complex scenes. A portable, handheld multi-camera system has been developed that allows to record multiple image streams by...

The composition and depth of the airway surface liquid (ASL) are key parameters in airway physiology that are thought to be important in the pathophysiology of cystic fibrosis and other diseases of the airways. We reported novel fluorescent indicator and microscopy methods to measure [Na+], [Cl-], pH, and depth of the ASL in large airways (Jayaraman, S., Y. Song, L. Vetrivel, L. Shankar, and A....
