This paper explores the geometric structure of spectrahedral cone, called symmetry adapted positive semidefinite (PSD) and Gram spectrahedron a symmetric polynomial. In particular, we determine dimension PSD describe its extremal rays, discuss matrix representations. We also consider spectrahedra for specific families polynomials including binary polynomials, quadratics, ternary quartics sextic...

We present the first fundamental simulation method for the determination of crater morphology due to femtosecond-pulse laser damage. To this end we have adapted the particle-in-cell (PIC) method commonly used in plasma physics for use in the study of laser damage and developed the first implementation of a pair potential for PIC codes. We find that the PIC method is a complementary approach to ...

The fauna collected by MAREANO represents a wealth of different life-forms, from sea cucumbers retrieved from 3000 meters depth to small crustaceans hidden in the sediments of fishing banks. They are all adapted for the environment in which they are living. Their morphology and behavior are fine-tuned to the specific environment they are living in, and their state of health indicates environmen...

Actin is a protein abundant in many cell types. Decades of investigations have provided evidence that it has many functions in living cells. The diverse morphology and dynamics of actin structures adapted to versatile cellular functions is established by a large repertoire of actin-binding proteins. The proper interactions with these proteins assume effective molecular adaptations from actin, i...

In this paper Brill’s rule-based PoS tagger is tested and adapted to Hungarian. It is shown that the present system does not obtain as high accuracy for Hungarian as it does for English because of the structural difference between these languages. Hungarian has rich morphology, is agglutinative with inflectional characteristics and has free word order. The tagger has the greatest difficulties w...

OBJECTIVES To determine the stability/reversibility and mechanism of monensin adaptation in monensin-treated cattle isolates compared with reference bacterial isolates, exposed in vitro to high monensin concentrations. METHODS We evaluated the potential for cattle-origin strains of Clostridium perfringens, Enterococcus faecium and Enterococcus faecalis exposed to monensin in vivo (in vivo mon...
