mixed malaria infections, plasmodium falciparum and p. vivax, are suspected to occur at a greater frequency than is detected by conventional light microscopy. in order to determine the year round pattern of transmission and the frequency of mixed infections in malaria endemic area, we carried out a prospective comparison of diagnosis by conventional light microscopy and nested pcr in chahbahar ...

the b cell is a vital contributor to humoral immunity. the b cell-specific antigen cd20 is expressed during b cell development, starting at the pre-b cell level and persists through b cell differentiation, but is lost during terminal differentiation to plasma cells. rituximab is a monoclonal antibody that destroys both normal and malignant b cells that have cd20 on their surfaces and is therefo...

Mammary mixed tumours are the most frequent neoplasias in female dogs. In humans, mixed tumours are frequently found in the salivary glands and are known as pleomorphic adenomas. In addition to their histomorphologic similarities, mixed tumours and pleomorphic adenomas have the potential to become malignant and give rise to carcinomas in mixed tumours and carcinomas ex-pleomorphic adenoma, resp...

Let G be a nonsingular connected mixed graph. We determine the mixed graphs G on at least seven vertices with exactly two Laplacian eigenvalues greater than 2. In addition, all mixed graphs G with exactly one Laplacian eigenvalue greater than 2 are also characterized. c © 2006 Elsevier Ltd. All rights reserved.

In this paper we study two operations of merging components in a chain graph, which appear to be elementary operations yielding an equivalent graph in the respective sense. At first, we recall basic results on the operation of feasible merging components, which is related to classic LWF (Lauritzen, Wermuth and Frydenberg) Markov equivalence of chain graphs. These results are used to get a graph...

We present Reflets, a mixed-reality environment for musical performances that allows for freely displaying virtual content on stage, such as 3D virtual musical interfaces or visual augmentations of instruments and performers. It relies on spectators and performers revealing virtual objects by slicing through them with body parts or objects, and on planar slightly reflective transparent panels t...
