An anticipatory agent [1] is a hybrid agent which is able to predict changes of itself and its environment. Such agents prove interesting [2] [3] [4] in embedded systems such mobile robots. Indeed, they combine a reactive fast layer with a cognitive layer capable to perform corrective actions to avoid undesired situations before they occur actually. We present in this paper a generic architectu...

Video streaming is in high demand by mobile users, as recent studies indicate. But in mobile networks fluctuating available data rates can degrade video quality and interrupt video playback. Assuming that we can predict data rates, we developed an anticipative approach to plan the quality and download time of the video segments ahead. This anticipatory scheduling avoids playback interruptions b...

the purpose of this study was to gain more information on the structure of different layers of renal arteryand comparing these structures in post-natal male and female sheep. to do so, right and left renal arteries of6 adult and 6 newborn animals were dissected; the middle parts of arteries were only collected. after tissueprocessing using paraffin embedding method, 5–6-μm sections were cut and...

The primate caudate nucleus plays a crucial role in transforming cognitive/motivational information into eye movement signals. A subset of caudate projection neurons fire before a visual target's onset. This anticipatory activity is sensitive to position-reward contingencies and correlates with saccade latency, which is shorter toward a rewarded position. We recorded single-unit activity of cau...

BACKGROUND The disorganized and negative dimensions of schizotypy are characterized by cognitive disorganization and anhedonia, respectively. The aim of the study was to investigate the relationships between these two dimensions of schizotypy by taking into account ambivalence and the distinction between consummatory and anticipatory anhedonia. METHODS Dimensional analysis and categorical ana...

This study investigated the relation between impaired anticipatory postural adjustments and bradykinesia in Parkinson's disease. Patients with Parkinson's disease and age matched controls stood on a platform. In one series of experiments, they performed fast, discrete shoulder flexion or extension movements. In another series, they were required to press a trigger with the right thumb and thus ...

The organization of the retinal nerve fiber layer of the cynomolgus monkey was studied by electron microscopy. Nerve fiber size spectra were obtained from measurements of every fiber in enlarged montages of selected bundles. Variation in spectra among nasal, arcuate, and papillomacular bundles was examined, and variation of spectra of a given bundle as it crossed the retina was determined. Amon...

Th e search for interventions to reduce avoidable readmissions aft er an exacerbation of COPD has attracted substantial attention aft er the Centers for Medicare & Medicaid Services included COPD exacerbations in its Hospital Readmissions Reduction Program. 1 We read with great interest the study by Jennings et al 2 in a recent issue of CHEST (May 2015) and applaud the authors for conducting a ...

National surveys have revealed significant differences in patient outcomes following admission to hospital with acute exacerbation of COPD which are likely to be due to variations in care. We developed a care bundle, comprising a short list of evidence-based practices to be implemented prior to discharge for all patients admitted with this condition, based on a review of national guidelines and...
