The DNA hypomethylating agent 5-azacytidine greatly increased the reactivation of alphaherpesvirus saimiri-1 (alpha HVS) from latently infected rabbit dorsal root ganglia, although it inhibited the virus yield and plaque formation efficiency of alpha HVS in Vero cells. 12-O-Tetradecanoylphorbol 13-acetate (a protein kinase C activator) and sodium n-butyrate both had a stimulating action on repl...

The edge and motion are the main features that human visual system (HVS) perceives intensively. This paper proposes an algorithm for the segmentation of the moving object with accurate boundary using color and motion focusing on the HVS perception in the general image sequence. The proposed algorithm is composed of three parts: color segmentation, motion analysis, and region refinement and merg...

| Due to limitations in bandwidth or storage space, many applications require compression of digital images. One of the main hindrances to progress in the area of image communications is the large amount of information contained in an image. In this paper we propose a wavelet-based image compression technique which incorporates some of the properties of the human visual system (HVS). A new wave...

The purpose of this study was to test the effect of high voltage stimulation (HVS) on edema reduction in the rat hindpaw. The animals were divided into a control group (n = 20) and a treated group (n = 20). The right hindpaw volume was measured, and then the animal's paw was traumatized. The animals in the treated group were treated with HVS at 24, 48, and 72 hours posttrauma. Paw volume measur...

Herpesvirus saimiri (HVS) was propagated in vero cells for 3 passages at 39 degrees and cloned 3 times at 34 degrees. This virus was inoculated into cotton-topped marmoset and squirrel monkeys; all inoculated monkeys became infected as HVS was reisolated after their circulating lymphocytes were cultured with vero cells and measurable levels of antiviral antibodies developed that were measured b...

In this project, two improved perceptual quality methods are proposed. One is weighted PSNR (WPSNR). Based on the fact that the human eye will have less sensitivity to modifications in textured areas than in smooth areas, WPSNR uses an additional parameter called the Noise Visibility Function (NVF) that is a texture masking function as a penalization factor. The other method based on Watson HVS...

We have analysed the matrilineal genetic composition of three self-reported ethnic groups from São Tomé e Príncipe (Gulf of Guinea), an African archipelago whose settlement begun in the late fifteenth century. Sequence data from the hypervariable segments I (HVS-I) and II (HVS-II) were obtained for 30 Angolares, 35 Forros and 38 Tongas. The repertory of mtDNA lineages in São Tomé e Príncipe den...

Herpesvirus saimiri (saimirine herpesvirus 2) (HVS), a T-lymphotropic tumor virus, induces lymphoproliferative disease in several species of New World primates. In addition, strains of HVS subgroup C are able to transform T cells of Old World primates, including humans, to permanently growing T-cell lines. In concert with the Stp oncoprotein, the tyrosine kinase-interacting protein (Tip) of HVS...

OBJECTIVE The hidden vector state (HVS) model is an extension of the basic discrete Markov model in which context is encoded as a stack-oriented state vector. It has been applied successfully for protein-protein interactions extraction. However, the HVS model, being a statistically based approach, requires large-scale annotated corpora in order to reliably estimate model parameters. This is nor...

In this paper, two new full-reference metrics for image quality assessment are presented. They are based on the Peak-Signal-to-Noise Ratio (PSNR) and Universal Quality Index (UQI) modified to take into account the Human Visual System (HVS) properties. Many studies confirm that the HVS is more sensitive to low frequency distortions rather than to high frequency ones. It is also very sensitive to...
