This paper describes Monitorix, a video-based traffic surveillance multi-agent system. Monitorix agents are grouped in four tiers, according to the kind of information processing they perform: the sensors and effectors tier, the objective description tier, the application assistant tier, and the user assistant tier. The video analysis algorithms use an(More)
Leber Congenital Amaurosis (LCA), the most severe inherited retinal dystrophy, is genetically heterogeneous, with 14 genes accounting for 70% of patients. Here, 91 LCA probands underwent LCA chip analysis and subsequent sequencing of 6 genes (CEP290, CRB1, RPE65, GUCY2D, AIPL1and CRX), revealing mutations in 69% of the cohort, with major involvement of(More)
György Dán introduced a study whose goal was to characterize the distribution of content-popularity metrics, in particular instantaneous and the download popularity in BitTorrent systems. To this end the authors conducted a practical study in which they used a Mininova.org screen scrape and a scrape of 721 of BitTorrent trackers. The study showed that it is(More)
Cornelia de Lange syndrome (CdLS) is a multisystem genetic disorder with distinct facies, growth failure, intellectual disability, distal limb anomalies, gastrointestinal and neurological disease. Mutations in NIPBL, encoding a cohesin regulatory protein, account for >80% of cases with typical facies. Mutations in the core cohesin complex proteins, encoded(More)
BACKGROUND The dental visit is a unique opportunity for tobacco control. Despite evidence of effectiveness in dental settings, brief provider-delivered cessation advice is underutilized. OBJECTIVE To evaluate an Internet-delivered intervention designed to increase implementation of brief provider advice for tobacco cessation in dental practice settings.(More)
The authors present two cases of purulent pericarditis secondary to pneumococcus pneumonia, a rare entity in the antibiotic era, one of them in an apparently healthy person. A systematized diagnostic approach to moderate pericardial effusion is presented, together with a review of purulent pericarditis. The presence of pericardial effusion with persistent(More)
This paper focuses on the identification of disfluent sequences and their distinct structural regions, based on acoustic and prosodic features. Reported experiments are based on a corpus of university lectures in European Portuguese, with roughly 32h, and a relatively high percentage of disfluencies (7.6%). The set of features automatically extracted from(More)
Isolated pulmonary valve endocarditis is a very rare entity, usually associated with intravenous drug abuse. We describe a case of isolated pulmonary valve endocarditis in a diabetic patient with no apparent precipitating factors besides a lesion on the right hallux. The clinical course was favorable and he was discharged home after a six-week course of(More)
The microphthalmia-associated transcription factor (MITF) is a basic helix-loop-helix leucine zipper transcription factor, which regulates melanocyte development and the biosynthetic melanin pathway. A notable relationship has been described between non-truncating mutations of its basic domain and Tietz syndrome, which is characterized by albinoid-like(More)
