The inclusive production of the ω(782) vector meson in hadronic Z decays is measured and compared to model predictions. The analysis is based on 4 million hadronic Z decays recorded by the ALEPH detector between 1991 and 1995. The production rate for x p = p meson /p beam > 0.05 is measured in the ω → π + π − π 0 decay mode and found to be 0.585 ± 0.019(More)
The full LEP-1 data set collected with the ALEPH detector at the Z pole during 1991-1995 is analysed in order to measure the τ decay branching fractions. The analysis follows the global method used in the published study based on 1991-1993 data, but several improvements are introduced, especially concerning the treatment of photons and π 0 's. Extensive(More)
We reviewed the results of imaging studies on 111 children and adolescents with partial epilepsy to determine which imaging procedure had the greatest sensitivity and specificity for partial epilepsy in this age range. All cases were classified as idiopathic, lesional, and cryptogenic epilepsy based on the 1989 International League Against Epilepsy(More)
Decades of experimentation with a variety of pharmacological treatments have identified some effective therapies for heroin addiction but not for cocaine addiction. This may be due, at least in part, to our incomplete understanding of the factors involved in the differential vulnerability to these addictions, which are often considered mere variations of(More)
Extensive preclinical data implicate corticotropin-releasing hormone (CRH), acting through its CRH1 receptor, in stress- and dependence-induced alcohol seeking. We evaluated pexacerfont, an orally available, brain penetrant CRH1 antagonist for its ability to suppress stress-induced alcohol craving and brain responses in treatment seeking alcohol-dependent(More)
The problem of detecting moving objects is very important in many application contexts such as people detection and recognition, visual surveillance both in indoor and outdoor environments, and so on. In this paper we propose a motion detection algorithm based on background subtraction and shadow removing. The main idea is to implement a fast and reliable(More)
Drug abuse is often seen as a unitary phenomenon, partly as a result of the discovery over the past three decades of shared mechanisms of action for addictive substances. Yet the pattern of drug taking is often very different from drug to drug. This is particularly evident in the case of 'club drugs', such as ketamine. Although the number of ketamine(More)
In Italy, little is known about the spectrum of adverse fetal effects related to maternal alcohol use during pregnancy. In this paper, we report on the phenotype of Italian children with fetal alcohol spectrum disorders (FASD). These data were gathered as part of a field study assessing the prevalence of FASD in children in an in-school study in a rural(More)
The triple gauge-boson couplings involving the W are determined using data samples collected with the ALEPH detector at mean centre-of-mass energies of 183 GeV and 189 GeV, corresponding to integrated luminosities of 57 pb −1 and 174 pb −1 , respectively. The couplings, g Z 1 , κ γ and λ γ , are measured using W-pair events, single-W production and single-γ(More)
Posttraumatic stress disorder (PTSD) and alcoholism are frequently comorbid, suggesting the possibility of overlapping neural substrates. The neurokinin 1 (NK1) receptor for substance P (SP) has been implicated in both stress- and alcohol-related behaviors. The NK1 antagonist aprepitant, clinically available as a treatment for chemotherapy-induced nausea,(More)
