In recent years, social commitment based approaches have been proposed to solve problems issuing from previous mentalistic based semantics for agent communication languages. This paper follows the same line of thought since it presents the latest version of our dialogue game based agent communication language – DIAlogue-Game based Agent Language (DIAGAL) –(More)
This paper presents a new approach to polyphonic music retrieval, based on a structured pattern representation. Polyphonic patterns are formed by joining and layering pattern components into sequences and simultaneities. Pattern components are conjunctions of features which encode event properties or relations with other events. Relations between events(More)
BACKGROUND Fine-needle aspiration is the procedure of choice for evaluating thyroid nodules. Core-needle biopsy (CNB) is not included in the American Thyroid Association recommendations for evaluating such nodules. CNB complications are classically bleeding and hematomas. To our knowledge, no case of arteriovenous fistula (AVF) secondary to a CNB has been(More)
OBJECTIVES Rigid bronchoscopy (RB) is the principal method used for the extraction of a tracheo-bronchial foreign body (FB), but its use as a diagnostic tool implies a certain rate of negative exams, exposing the child to the risk of procedure and anesthesia-related complications. Technological progress has improved the accuracy and availability of(More)
This paper develops and applies a new method for the discovery of polyphonic patterns. The method supports the representation of abstract relations that are formed between notes that overlap in time without being simultaneous. Such relations are central to understanding species counterpoint. The method consists of an application of the vertical viewpoint(More)
A higher level of interdisciplinary collaboration between music information retrieval (MIR) and musicology has been proposed both in terms of MIR tools for musicology, and musicological motivation and interpretation of MIR research. Applying association mining and content citation analysis methods to musicology references in ISMIR papers, this paper(More)
We report a unique case of extensive bilateral arteriovenous malformation (AVMs) in a child's mandible, discuss treatment options and review literature. A healthy 8 year-old girl presented with bright blood of unknown source found on her pillow. Three large AVMs involving the symphyseal region and bilateral mandibular bodies were found on angiography. Due(More)
