The analytic center of an n dimensional polytope P fx R aTi x bi i m g with a nonempty interior Pint is de ned as the unique minimizer of the logarithmic potential function F x Pmi log aTi x bi over Pint It is shown that one cycle of a conjugate direction method applied to the potential function at any v Pint such that q v Tr F v generates a point x Pint such that q x Tr F x pn

Many nonlinear quantum phenomena of intense laser-atom physics can be intuitively explained with the concept of trajectory. In this paper, Bohmian mechanics (BM) is introduced to study a multiphoton process of atoms interacting with the intense laser field: above-threshold ionization (ATI). Quantum trajectory of an atomic electron in intense laser field is obtained from the BohmNewton equation ...

The alveolar epithelium represents a major site of tissue destruction during lung injury. It consists of alveolar epithelial type I (ATI) and type II (ATII) cells. ATII cells are capable of self-renewal and exert progenitor function for ATI cells upon alveolar epithelial injury. Cell differentiation pathways enabling this plasticity and allowing for proper repair, however, are poorly understood...

BACKGROUND Human immunodeficiency virus type 1 (HIV-1) vaccines directed to the cell-mediated immune system could have a role in lowering the plasma HIV-1 RNA set point, which may reduce infectivity and delay disease progression. METHODS Randomized, placebo-controlled trial involving HIV-1-infected participants who received a recombinant adenovirus serotype 5 (rAd5) HIV-1 gag vaccine or place...

This study evaluates the effects of an acute treatment with a Centella asiatica (CA) extract on the biodistribution of the radiopharmaceutical NaTcO4 and on the fixation of technetium-99m on blood constituents. Wistar rats were treated with CA extract and, 1 hour after, NaTcO4 was administered; organs/tissues were withdrawn and weighted. The radioactivity was counted to calculate the percentage...

Spheroidin (SPH) is the most highly expressed gene of the entomopoxvirus isolated from Amsacta moorei (AmEPV). The level of expression of poxvirus genes is believed to be governed in large part by the promoter. Poxvirus promoters generally consist of approximately 40 bp which frequently terminate at the 3' end with a translation initiating TAAATG sequence. We have examined the requirements for ...

Vellozia pusilla Pohl is a species of the botanic family Velloziaceae that occurs in the subtropical regions of South America and, although it lives under conditions of high solar irradiation and low water availability, shows great longevity. The methanol extract of roots, stem and leaf sheaths of this species showed an antitumoral activity through the inhibition of the enzyme Topoisomerase I w...

The ideal choices for the tasks presented in the project proposal would be the NVIDIA CUDA toolkit (http://developer.nvidia.com/object/cuda. html), which exposes more underlying architecture to programmers. However, the package requires a capable NVIDIA video card, and we could not get for this project. ATI also designed a similar platform “Close-to-Metal (CTM) Device” (http://ati.de/companyinf...
