OBJECTIVES To compare the physiological and anthropometric characteristics of specific playing positions and positional playing groups in junior rugby league players. METHODS Two hundred and forty junior rugby league players underwent measurements of standard anthropometry (body mass, height, sum of four skinfolds), muscular power (vertical jump), speed (10, 20, and 40 m sprint), agility (L r...

Positional behavior in adult red colobus monkeys (Colobus badius) was examined in a variety of ecological contexts. Using a focal-animal methodology, we assessed how data collected by different observers, in different years, in different seasons, and in different forests affected estimates of positional behavior. In all, 23,000 bouts were recorded. Variation in frequency is greatest in the comm...

The suppression of the regenerative chatter phenomenon in turning process via the variation of the frequency and amplitude of the spindle motor excitation is carried out in this research. A programmable inverter is employed for variable periodic excitation of the spindle motor. A set of turning experiments is designed and performed on a number of conical work pieces both in constant spindle spe...

OBJECTIVE To assess the effect of uvulopalatopharyngoplasty (UPPP) on positional dependency in patients with obstructive sleep apnea (OSA). DESIGN Retrospective analysis. SETTING Tertiary care university hospital. PATIENTS Ninety-six patients who underwent UPPP because of OSA from June 1, 2004, through July 31, 2008, were included. Both preoperative and postoperative attended full-night p...

Linear Go is the game of Go played on the 1×n board. Positional Linear Go is Linear Go with a rule set that uses positional superko. We explore gametheoretic properties of Positional Linear Go, and incorporate them into a solver based on MTD( f ) search, solving states on boards up to 1×9.

BACKGROUND Positional therapy that prevents patients from sleeping supine has been used for many years to manage positional obstructive sleep apnea (OSA). However, patients' usage at home and the long term efficacy of this therapy have never been objectively assessed. METHODS Sixteen patients with positional OSA who refused or could not tolerate continuous positive airway pressure (CPAP) were...
