The aim of this research is to forecast the movement of SP&500 weekly. Support Vector Machine Classifier (SVMC) is used in order to examine the data. The data covers the period between 28/11/1997 and 29/12/2010. The inputs are technical analysis indicators such as the Moving Average Convergence Divergence (MACD) and the Relative Strength Index (RSI). SVMC is used to optimize the values of the M...

OBJECTIVE Laryngopharyngeal reflux (RFL) is diagnosed by the presence of laryngeal signs and symptoms. Some studies have noted that signs and symptoms may be non- specific and may have poor correlation. The goal of this study was to assess correlation of the reflux finding score (RFS) and reflux symptom index (RSI) as a fibroendoscopic assessment protocol. PATIENTS AND METHOD A sample of 34 c...

The purpose of this study was to assess the relationships between common measures of stretch shortening cycle function during a drop jump. Fifteen males from team sports performed three drop jumps from a height of 0.3 m onto a force platform. Ground contact time (CT), flight time (FT), height jumped (HJ), reactive strength index (RSI), reactive strength ratio (RSR) and vertical leg-spring stiff...

BACKGROUND To assess the prevalence of laryngopharyngeal reflux (LPR) in the Greek general population and its risk factors. METHODS Questionnaire based epidemiological, adult participants' survey. The Reflux Symptom Index (RSI) was used for the assessment of LPR prevalence. The RSI questionnaire was completed by 340 (183 male and 157 female) randomly selected subjects. Subjects with RSI score...

BACKGROUND The ratio of systolic blood pressure (SBP) to heart rate (HR), called the reverse shock index (RSI), is used to evaluate the hemodynamic stability of trauma patients. To minimize undertriage in emergency departments (EDs), we evaluated whether RSI < 1 (i.e., SBP lower than HR) could be used as an additional variable to identify patients at high risk for more severe injury within a le...

This study investigated whether lying requires executive control using a reaction-time based lie test. We hypothesized that (1) goal neglect induced by a long response-stimulus interval (RSI; 5-8s) would make lying harder relative to a short RSI (.2 s) that promoted attentional focus, and (2) participants whose executive control resources were depleted by an initial executive control task would...

We examined the hypothesis that fish species with similar ecomorphological patterns, but from different taxonomic groups, would use similar feeding modes. We contrasted the feeding behavior of Micropterus salmoides (Lacépède) (Centrarchidae) and Cichla ocellaris (Block and Schneider) (Cichlidae), both large-mouthed piscivores with a locomotor morphology designed for fast acceleration, with Lepo...

PURPOSE We assessed the utility of diffusion-weighted imaging (DWI) with relative signal intensity (rSI) statistical thresholding for delineating prostate cancer tumors. MATERIALS AND METHODS Seventeen patients with prostate cancer underwent DWI before total prostatectomy. We measured standard deviation (SD) of the signal intensity (SI) of the lesser pelvic space at DWI, created rSI maps, dis...

OBJECTIVES To assess the efficiency of a short-stay unit (SSU) for undifferentiated medical patients and evaluate its effect on the overall efficiency of a general medicine department. DESIGN, SETTING AND PATIENTS Retrospective study of all general medical patients admitted to the SSU at Flinders Medical Centre, South Australia, during its 5 years of operation (2005-2009), compared with 4 yea...

This study examined the relationship between lower body power and repeated as well as single sprint performance in soccer players. The performance of nineteen male soccer players was examined. The first testing session included the countermovement jump (CMJL) and the progressive full squat (FSL), both with external loads. Power in the CMJL and FSL was measured with each load that was lifted. Th...
