This article discusses in detail the rating system that won the kaggle competition “Chess Ratings: Elo vs the rest of the world”. The competition provided a historical dataset of outcomes for chess games, and aimed to discover whether novel approaches can predict the outcomes of future games, more accurately than the well-known Elo rating system. The rating system, called Elo++ in the rest of t...

Establishing a reliable rating curve is an integral part of water resource engineering. The present paper is a review of data driven techniques used for modelling the stage discharge relationship over the last two decades. Over the year’s several data driven techniques such as ANN, SVM, MT, fuzzy logic and GA have been applied by researchers in quest of arriving at a reliable technique to model...

OBJECTIVE To develop a reliable and valid parent-report screening instrument for mania, based on DSM-IVsymptoms. METHOD A 21-item Child Mania Rating Scale-Parent version (CMRS-P) was completed by parents of 150 children (42.3% female) ages 10.3 +/- 2.9 years (healthy controls = 50; bipolar disorder = 50; attention-deficit/hyperactivity disorder [ADHD] = 50). The Washington University Schedule...

BACKGROUND AND PURPOSES MR imaging is now widely used to monitor disease progression in patients with multiple sclerosis (MS). The purpose of this study was to explore the relationship between disability status and existing and new MR parameters in MS patients. METHODS Forty-one patients with clinically definitive MS were studied. MR imaging included T2- and T1-weighted imaging as well as gra...

AIMS Coronary heart disease is prevalent in the working-age population. Traditional outcome measures like mortality and readmission are of importance to evaluate the prognosis but are hardly sufficient. Ability to work is an additional outcome of clinical and societal significance. We describe trends and predictors of Return To Work (RTW) after PCI and describe a possible benefit using patient-...

[1] River suspended-sediment concentrations provide insights to the erosion and transport of materials from a landscape, and changes in concentrations with time may result from landscape processes or human disturbance. Here we show that suspended-sediment concentrations in the Santa Ana River, California, decreased 20-fold with respect to discharge during a 34-year period (1968 2001). These dec...

Existing guidelines for the number of ultrasounds required before clinical competency are based not on scientific study but on consensus opinion. The objective of this study was to describe the learning curve of limited right upper quadrant ultrasound. This was a prospective descriptive study. Ultrasounds collected over 1 year were reviewed for interpretive and technical errors. Possible errors...

The uncertainty in mean discharge from two large South American rivers (the Amazonas at Obidos, Brazil, and the Parana at Corrientes, Argentina) resulting from variation in the data used to fit rating curves at the two sites is evaluated. For the Amazonas at Obidos, where mean annual discharge over the 27-year period 19701996 was 164 200 m s'\ uncertainty arising from rating curve variability a...

The relationships between water level and discharge along the river channel are vital for decision support systems in river basin management. Normally the reliability of the so-called rating curves along the river channel depends greatly on the accuracy and duration of the measured discharge and water level data. In the Elbe Decision Support System (DSS), the rating curves are combined with the...

UNLABELLED To evaluate patients undergoing arthroscopic release of a stiff elbow, with discussion of the technique, possible difficulties and risks. METHODS Twenty-four elbow arthroscopy procedures were performed. All the patients were evaluated using goniometry before the operation and six months afterwards and were rated using the Mayo elbow performance score (MEPS). RESULTS Fifteen men a...
