objective: this study aimed to describe the characteristics of iran’s child and adolescent mental health research published from 1973 to 2002. method: the articles were drawn from iranpsych, which is a national database of published research in mental health and related fields. this database gathers scientific papers on psychiatry, psychology, and neuroscience published in both national and int...

OBJECTIVE Electronic medical records (EMRs) are a rich data source for discovery research but are underutilized due to the difficulty of extracting highly accurate clinical data. We assessed whether a classification algorithm incorporating narrative EMR data (typed physician notes) more accurately classifies subjects with rheumatoid arthritis (RA) compared with an algorithm using codified EMR d...

X.efficiency theory challenges the maximization postulate of standard economic theory. This paper shows that X-inefficiency is. at times, as much as 30 times greater than allocative inefficiency and suggests reasons for the existence of X-inefficiency—-i.e., (a) incomplete employment contracts, (b) discretionary effort, and (c) nonmaximization of profits.

In the near future, mobile devices are expected to have a storage capacity comparable to today’s desktop machines. As the amount of infomation grows, conventional search tools become less effective. To meet these challenges, we turn to desktop search. This paper presents Dessy, aDESktop Search directorY system for mobile and desktop computers alike. It allows a user to find files by their conte...

An image attention model and its application to image quality assessment are discussed in this paper. The attention model is based on rarity quantification, which is related to self-information to attract the attention in an image. It is relatively simpler than the others but results in taking more consideration of global contrasts between a pixel and the whole image. The visual attention model...

PURPOSE Metabolic syndrome (MS), which is framed by cardiovascular risk factors such as hypertension, obesity, glucose intolerance and dyslipidemia, is thought to be associated with the rheumatic diseases. The aim of this study is to examine the frequency of metabolic syndrome (MS) and insulin resistance in patients with rheumatoid arthritis (RA) and to examine the effect of the inflammation sy...

The development of automated methods for revealing the repetitive structure of a given music recording is of central importance in music information retrieval. In this paper, we present a novel scape plot representation that allows for visualizing repetitive structures of the entire music recording in a hierarchical, compact, and intuitive way. In a scape plot, each point corresponds to an audi...

The title compound, C(8)H(18)N(4)O(2) (2+)·2Cl(-), contains two oxime groups. The methyl oxime group has a Z configuration, and the ethyl oxime group is disordered, with both Z and E configurations in occupancies of 0.840 (8) and 0.160 (8), respectively. In the crystal structure, there are a number of N-H⋯Cl hydrogen bonds.

Modified tau is a parameter computed by ACAS to estimate the earliest time at which a collision could occur should an intruder aircraft accelerate toward the own aircraft. A concern with the modified tau calculation has been raised in a class of encounters where intruders are already close and converging slowly. In these problem cases, ACAS may induce a Near Mid-Air Collision by generating RAs ...
