conclusions the results of the study show no significant association between norepinephrine transporter polymorphism scl6a2 and adhd. results the percentages of adhd subtypes for combined, inattentive, and hyperactive/impulsive were 72.2%, 17.2%, and 11.9%, respectively. there was no significant association between norepinephrine transporter polymorphism and adhd (p = 0.81). moreover, no signif...

Segmentation of news videos into stories is among key issues for achieving efficient treatment of news-based digital libraries. Indeed, anchor shot detection is a fundamental step for segmenting news into stories. In this paper we present an improved algorithm for anchor shot detection. It is based on a graph theoretical clustering method and exploits the idea of the cluster lifetime for improv...

Recently, large-scale distributed systems are being developed. Owing to the high construction cost, the lifetime of the systems are prolonged. Therefore, it is an important problem to achieve exible distributed systems by introducing some mechanism in the system software for updating application software. The system cannot be kept highly available by the conventional updating methods because mu...

After an introductory section summarizing the paleontological data and some of their theoretical descriptions, we describe thèreset' model and its (in part analytically soluble) mean eld version, which have been brieey introduced in Letterss1, 2]. Macroevolution is considered as a problem of stochastic dynamics in a system with many competing agents. Evolutionary events (speciations and extinct...

OBJECTIVE The purpose of this study was to compare sociodemographic and family history correlates, symptomatic presentation, and comorbidity with Axis I and Axis II disorders, in an epidemiologic sample of adults with DSM-IV antisocial personality disorder (ASPD) who lacked, vs those who did not lack, remorse. METHODS This study is based on a nationally representative sample of adults. Lifeti...

BACKGROUND A nationally representative study of psychiatric disorders in South Africa provided an opportunity to study the association between perpetration of human rights violations (HRVs) during apartheid and psychiatric disorder. Prior work has suggested an association between perpetration and post-traumatic stress disorder (PTSD), but this remains controversial. METHODS Subjects reported ...

BACKGROUND Increasing literature has been focused on complicated grief (CG) and its distinctiveness from other potentially loss related mental disorders such as major depression (MD). In this regard, symptoms of separation distress seem to play a key role. The aim of this study was to compare the clinical features of CG to those of MD and of CG+MD, with particular attention to separation anxiet...

BACKGROUND Non-suicidal self-injury (NSSI) is a proposed new "condition for further study" in the DSM-5. To date no prevalence data has been available on this diagnostic entity from a representative sample of the general population. METHODS A representative sample of the German population (N = 2509, mean age = 48.8 years, SD = 18.1, female 55.4 %) completed the NSSI section of the German vers...

Broadcasting is a common and basic operation used to support various network protocols in wireless networks. To achieve energy-efficient broadcasting is especially important for ad hoc wireless sensor networks because sensors are generally powered by batteries with limited lifetimes. Energy consumption for broadcast operations can be reduced by minimizing the number of relay nodes based on the ...
