The transmembrane subunit (TM) of the avian leukosis and sarcoma virus (ALSV) envelope glycoprotein (Env) contains a stretch of conserved hydrophobic amino acids internal to its amino terminus (residues 21 to 42). By analogy with similar sequences in other viral envelope glycoproteins, this region has been proposed to be a fusion peptide. We investigated the role of this region by changing each...

UNLABELLED Cochlear implants may improve the medical and social prognosis of profound deafness. Nevertheless, some patients have experienced poor results without any clear explanations. One correlate may be an alteration in cortical voice processing. To test this hypothesis, we studied the activation of human temporal voice areas (TVA) using a well-standardized PET paradigm adapted from previou...

The present study investigated whether consuming dairy products naturally enriched in cis-9, trans-11 (c9,t11) conjugated linoleic acid (CLA) by modification of cattle feed increases the concentration of this isomer in plasma and cellular lipids in healthy men. The study had a double-blind cross-over design. Subjects aged 34-60 years consumed dairy products available from food retailers for 1 w...

Suction feeding fish differ in their capacity to generate subambient pressure while feeding, and these differences appear to relate to morphological variation. We developed a morphological model of force transmission in the fish head and parameterized it with measurements from individual fish. The model was applied to 45 individuals from five species of centrarchid fishes: Lepomis macrochirus, ...

This article proposes a hybrid numerical-analytical approach to effectively predict the sound absorption coefficient of complex periodic metamaterials with reasonably low computation time. A variation an existing metamaterial, consisting succession necks and cavities, is also proposed. The design was intended decrease frequencies resonant peaks consists in adding eccentricity neck position. com...

This paper describes a software system that provides significant new capabilities for visualization and analysis of network attack graphs produced through Topological Vulnerability Analysis (TVA). The TVA approach draws on a database of known exploits and system vulnerabilities to provide a connected graph representing possible cyber-attack paths within a given network. Our visualization approa...

The purpose of this study is to determine the financial performance that influences transaction volume activity and stock returns as moderation in retail. data used by researchers secondary form annual accounts retail companies listed on Indonesian Stock Exchange. This survey method, which targets 21 trading companies, uses multiple regression analysis methods. two dependent variables have a ne...

In human communication, direct speech (e.g., Mary said, "I'm hungry") is perceived as more vivid than indirect speech (e.g., Mary said that she was hungry). This vividness distinction has previously been found to underlie silent reading of quotations: Using functional magnetic resonance imaging (fMRI), we found that direct speech elicited higher brain activity in the temporal voice areas (TVA) ...

A neural theory of visual attention (NTVA) is presented. NTVA is a neural interpretation of C. Bundesen's (1990) theory of visual attention (TVA). In NTVA, visual processing capacity is distributed across stimuli by dynamic remapping of receptive fields of cortical cells such that more processing resources (cells) are devoted to behaviorally important objects than to less important ones. By use...
