AIM To study the coexistence of subthreshold diagnoses of both attention deficit hyperactivity disorder (ADHD) and disruptive behaviour disorders (DBD) with other symptoms of child and adolescent psychiatric disorders as well as risk behaviours associated with smoking, alcohol and drug use. METHODS A population-based sample of twins including 177 girls and 135 boys was interviewed using the S...

A Satellite Attitude Dynamics Simulator (SADS) has been developed to facilitate the research and development of spacecraft flight attitude control software at the Naval Postgraduate School in Monterey, CA. The simulator provides a real-time 3 degree of freedom (3DOF) synthetic spacecraft hardware-in-the-loop environment, that includes realistic angular motions, sensor-effector delays, and contr...

Received: February 11, 2016 Revised: June 24, 2016 Accepted: June 24, 2016 Abstract: Background: Supraglottic airway devices (SADs) are very useful airway adjunct in managing anticipated and unanticipated difficult airway and can be used as a ventilating aid and as a conduit for tracheal intubation. The new versions of SADs like i-gel and intubating laryngeal mask airway (ILMA), have advantage ...

RESULTS Sudden arrhythmic death syndrome (SADS) was the most prevalent cause of death (n 1⁄4 149 [42%]). Myocardial disease was detected in 40% of cases, including idiopathic left ventricular hypertrophy (LVH) and/or fibrosis (n 1⁄4 59, 16%); arrhythmogenic right ventricular cardiomyopathy (ARVC) (13%); and hypertrophic cardiomyopathy (HCM) (6%). Coronary artery anomalies occurred in 5% of case...

The frequency distribution of species abundances [the species abundance distribution (SAD)] is considered to be a fundamental characteristic of community structure. It is almost invariably strongly right-skewed, with most species being rare. There has been much debate as to its exact properties and the processes from which it results. Here, we contend that an SAD for a study plot must be viewed...

Supra-arcade downflows (SADs) are dark structures descending towards post-reconnection flare loops observed in extreme ultraviolet or X-ray observations and closely related to magnetic reconnection during solar flares. Due the lack of statistical study on SADs a single flare, evolutions kinematic thermal properties process still remain obscure. In this work, we identified 81 that occurred 2013 ...

Introduction Standardized instruments have been increasingly used in the psychiatric assessment of children and adolescents in clinical and research settings. There are many instruments with different characteristics which vary according to their purposes such as diagnostic formulation, identification of symptoms, on the assessment of personality and emotional dynamics or cognitive development....

BACKGROUND Semi-structural clinical interviews are very important in the area of mental health research and services. There were no studies of the reliability and validity of the Farsi (Persian) version of Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL) in Iran. This study compares the results of face-to-face, semi-structural interview and clin...

The principle ADS asserts that every linear order on ω has an infinite ascending or descending sequence. This has been studied extensively in the reverse mathematics literature, beginning with the work of Hirschfeldt and Shore [16]. We introduce the principle ADC, which asserts that every such linear order has an infinite ascending or descending chain. The two are easily seen to be equivalent o...
