The core of current-generation high-performance multiprocessor systems is out-of-order execution processors with aggressive branch prediction. Despite their relatively high branch prediction accuracy, these processors still execute many memory instructions down mispredicted paths. Previous work that focused on uniprocessors showed that these wrong-path (WP) memory references may pollute the cac...

This paper outlines technical and aesthetic approaches to sound spatialization for electroacoustic music composition. In particular, the paper discusses how spatialization (sound diffusion) can be used to realize specific musical objectives. Technological solutions to problems associated with adapting multichannel compositions for live spatialization are explored, with particular reference to t...

Visual context often plays a crucial role in visual processing. In the domain of visual motion processing, the response to a stimulus presented to a neuron's classical receptive field can be modulated by presenting stimuli to its surround. The nature of these center-surround interactions is often inhibitory; the neural response decreases when the same direction of motion is presented to center ...

The objective of this study was to determine the effect of dietary supplementation with whey powder (WP, 1g/kg feed) from weaning to slaughter (150 d) on dry-aged loin quality of pigs. Fifty-eight pigs were randomly divided into two dietary treatment groups (seven replications of four pigs per treatments). Basal diet with 0.1% whey powder was supplied to the WP group. Basal diet was used for th...

Signal decomposition methods like Wavelet Transform (WT) have been widely used in a large set of applications such as image, speech and biomedical signal processing, reporting good results. In this paper, two versions of the WT are analyzed: the Discrete Wavelet Transform (DWT) and the Wavelet Packets (WP). The DWT is implemented by means of a filter bank with a fixed structure that provides a ...

We model the responses of cells in visual area VI during natural vision. Our model consists of a classical energy mechanism whose output is divided by nonclassical gain control and texture contrast mechanisms. We apply this model to review movies, a stimulus sequence that replicates the stimulation a cell receives during free viewing of natural images. Data were collected from three cells using...

This study was aimed at the chemical composition and inhibitory effects of walnut polyphenols (WP) in vitro lipase activity and on obesity in obese mice models. More than 20 individual phenolics such as gallotannins, ellagitannins, flavonoids and phenolic acids were identified in WP. Studying the interactions between porcine pancreatic lipase (PL) and WP were based on fluorescence quenching and...

Previous research has found that people are seen as more attractive when they appear in a group rather than in isolation. Do faces that surround us in time also affect how attractive we seem? Participants rated the attractiveness of famous female faces presented in a sequence of three and in isolation. We found that people do integrate information about attractiveness over time, but that tempor...
