This paper describes the effect of site of lesion on auditory detection, discrimination and speech processing. Three groups of ten patients with confirmed pathology of the eighth nerve and right and left temporal cortex and two normal-hearing control groups, differing with respect to hospitalization, participated. In each of the fifty subjects, measurements(More)
Local cerebral blood flow was measured in rats by the 14C-labeled iodoantipyrine technique with quantitative autoradiography during the processing of environmental stimuli. Presentation of a tone increased blood flow in the auditory but not the visual pathway. When the animal had previously been conditioned to fear the tone, blood flow additionally(More)
The importance of endogenous prostaglandins (PGs) in regulating CRF release was investigated by administering the PG synthesis inhibitor, indomethacin (Ind), in specific hypothalamic regions to adult female rats. Solid Ind pellets placed in the anterior hypothalamic area (AHA) significantly reduced the elevated levels of plasma corticosterone normally(More)
OBJECTIVE To test and develop, using structural equation modeling, a robust model of the mediational pathways through which health warning labels exert their influence on smokers' subsequent quitting behavior. METHOD Data come from the International Tobacco Control Four-Country Survey, a longitudinal cohort study conducted in Australia, Canada, the United(More)
This paper describes the design features, data collection methods and analytical strategies of the ITC China Survey, a prospective cohort study of 800 adult smokers and 200 adult non-smokers in each of six cities in China. In addition to features and methods which are common to ITC surveys in other countries, the ITC China Survey possesses unique features(More)
Recordings were made from units in or near nucleus ambiguus (NA) in the awake, drug-free dog while arterial pressure (AP) was increased and decreased nonpharmacologically by inflating occlusion cuffs that had been placed around the descending aorta and inferior vena cava, respectively. Units were recorded differentially through floating fine-wire electrodes(More)
BACKGROUND Although socio-economic factors have been identified as one of the most important groups of neighbourhood-level risks affecting birth outcomes, uncertainties still exist concerning the pathways through which they are transferred to individual risk factors. This poses a challenge for setting priorities and developing appropriate community-oriented(More)
BACKGROUND China currently does not have comprehensive laws or regulations on tobacco advertising and promotion, although it ratified the World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC) in October 2005 and promised to ban all tobacco advertising by January 2011. Much effort is needed to monitor the current situation of tobacco(More)
The International Tobacco Control (ITC) Policy Evaluation Survey of China uses a multi-stage unequal probability sampling design with upper level clusters selected by the randomized systematic PPS sampling method. A difficulty arises in the execution of the survey: several selected upper level clusters refuse to participate in the survey and have to be(More)
In this article, a new method for performance evaluation of Turbo-like codes is presented. This is based on estimating the Probability Density Function (pdf) of the bit Log-Likelihood-Ratio (LLR) using higher order statistics. We do not restrict ourselves to any specific model for the pdf and try to estimate it directly using a Cumulant matching method.(More)
