We have implemented a novel approach for robust ontology design from natural language texts by combining Discourse Representation Theory (DRT), linguistic frame semantics, and ontology design patterns. We show that DRT-based frame detection is feasible by conducting a comparative evaluation of our approach and existing tools. Furthermore, we define a(More)
Our aim was to perform a comprehensive analysis of the global and segmental features of gait in patients with genetically confirmed inherited ataxias. Sixteen patients with autosomal dominant (spinocerebellar ataxia, SCA1 or 2) or recessive (Friedreich’s ataxia, FRDA) ataxia were studied. We used a motion analysis system to record gait kinematic and kinetic(More)
We present Tı̀palo, an algorithm and tool for automatically typing DBpedia entities. T̀ıpalo identifies the most appropriate types for an entity by interpreting its natural language definition, which is extracted from its corresponding Wikipedia page abstract. Types are identified by means of a set of heuristics based on graph patterns, disambiguated to(More)
People with Parkinson's disease (PD) often have a posture characterized by lateral trunk flexion poorly responsive to antiparkinsonian drugs. To examine the effects of a rehabilitation programme (daily individual 90-minute-sessions, 5-days-a-week for 4-consecutive weeks) on lateral trunk flexion and mobility, 22 PD patients with mild to severe lateral trunk(More)
Increased antagonist muscle co-activation, seen in motor-impaired individuals, is an attempt by the neuromuscular system to provide mechanical stability by stiffening joints. The aim of this study was to investigate the co-activation pattern of the antagonist muscles of the ankle and knee joints during walking in patients with cerebellar ataxia, a(More)
Aemoo is a Web application supporting exploratory search over the Semantic Web. Through a simple keyword-based search interface, users can query Aemoo for information about any entity, which is then collected by aggregating knowledge from diverse sources such as linked data, Wikipedia, Twitter, and Google News. Such aggregation is performed according to(More)
The vestibulo-ocular reflexes (VORs) were studied in guinea pigs receiving daily administration of aminoglycoside antibiotics. The vestibular epithelia were also examined by scanning electron microscope technique (SEM). The treatment with aminoglycosides led to varying degrees of VORs according to (i) the type of aminoglycoside drug; (ii) the duration of(More)
Cerebellar ataxia is associated with unsteady, stumbling gait, and affected patients report a high rate of falls, particularly during locomotor tasks. U-turns (180° turns while walking) require a high level of coordination in order to completely reverse the body trajectory during ongoing motion, and they are particularly challenging for patients with(More)
Selected areas of sensorimotor cortex were stimulated with short trains adequate to evoke focal movements. Neurons belonging to the vestibular nuclear complex, including the lateral vestibular nucleus (LVN), were mainly affected by the stimulation of wrist-elbow, shoulder and cortical areas. The units responded to cortical stimulation either with a constant(More)
Twenty four workers (10 involved in the preparation and 14 in administration) exposed to cyclophosphamide (CP) and ifosfamide (IF) in two Italian hospitals were monitored. The extent of exposure was assessed by the analysis of air samples, wipe samples, pads and gloves. Urinary excretion at the beginning and at the end of the work shift was also measured by(More)
