Cystic fibrosis (CF) is primarily characterised by bronchiectasis and trapped air on chest computed tomography (CT). The revised Cystic Fibrosis Questionnaire respiratory symptoms scale (CFQ-R RSS) measures health-related quality of life. To validate bronchiectasis, trapped air and CFQ-R RSS as outcome measures, we investigated correlations and predictive values for pulmonary exacerbations. CF ...

Stepwise one-electron reduction of oxygen to water produces reactive oxygen species (ROS) that are chemically and biochemically similar to reactive sulfide species (RSS) derived from one-electron oxidations of hydrogen sulfide to elemental sulfur. Both ROS and RSS are endogenously generated and signal via protein thiols. Given the similarities between ROS and RSS, we wondered whether extant met...

Content syndication through RSS is gaining wide acceptance, and it is envisaged that feed aggregators will be provided as a commodity in future browsers. As we consume more of our information by way of RSS feeds, search mechanisms other than simple keyword search will be required. To this end, advances in semantic tooling can effectively improve the current state of the art in feed aggregators....

Nowadays, RSS is becoming a hot topic for Web applications. A lot of famous Web sites have provided RSS for users. However, making RSS files manually is boring, and so far, most sites haven’t provided such a service. In this paper, we mainly describe the design, implementation and evaluation of HTML2RSS, a system to extract content from HTML Web pages based on DOM structure, and generate RSS fi...

This month we continue our discussion of graphics in R. This month we examine histogram generation, 1-D and 2-D kernel density estimation. The GNU S language, "R" is used to implement this procedure. R is a statistical programming environment that utilizes the S and S-Plus language developed at Lucent Technologies. In the following document we illustrate the use of a GNU Web interface to the R ...

This month we demonstrate the use of robust estimators of location using the GNU S-Plus language, "R". R is a statistical programming environment that is a clone of the S and SPlus language developed at Lucent Technologies. In the following document we will illustrate the use of a GNU Web interface to the R engine on the "rss" server, http://rss.acs.unt.edu/cgi-bin/R/Rprog. This GNU Web interfa...

Extreme and non-extreme response styles (RSs) are prevalent in survey research using Likert-type scales. Their effects on measurement invariance (MI) in the context of confirmatory factor analysis are systematically investigated here via a Monte Carlo simulation study. Using the parameter estimates obtained from analyzing a 2007 Trends in International Mathematics and Science Study data set, a ...

Location estimation is a crucial component of location-aware applications. Positioning based on received signal strength (RSS) in wireless networks is considered a promising and inexpensive solution. Existing techniques only use RSS from some fixed access points (APs) deployed within the area of interest to estimate user location. Through experiments on the properties of RSS, it is found that R...
