Aura is a new sound synthesis system designed for portability and flexibility. Aura is designed to be used with W, a real-time object system. W provides asynchronous, priority-based scheduling, supporting a mix of control, signal, and user interface processing. Important features of Aura are its design for efficient synthesis, dynamic instantiation, and synthesis reconfiguration. operating syst...

In our work on AURA, we are dealing with (controlled) natural language queries to a scientific knowledge base, and this paper explores the extent to which Popescu et al’s framework can be applied in the AURA context. The AURA task differs from the database task in several important ways, in particular the variety and complexity of questions is much more open-ended than in Popescu et als databas...

We present an estimation of the expected number of arcs and arclets in a sample of nearby (z < 0.1) clusters of galaxies, that takes into account the magnitude limit of the Visiting Astronomer at Cerro Tololo Inter-American Observatory. CTIO is operated by AURA, Inc. under contract to the National Science Foundation.

BACKGROUND Synesthesia is, as visual migraine aura, a common and fascinating perceptual phenomenon. Here we present a unique case with synesthesias exclusively during visual migraine auras. CASE PRESENTATION A 40-year-old woman with a cyclic mood disorder had suffered from migraine with visual aura for several years. On several occasions she had experienced "mixing of senses" during the aura ...

Persistent migraine aura without infarction is a rare but well documented condition. According to the International Headache Society (HIS) criteria, this disturbance is defined by the persistence of a migraine aura for more than one week without radiographic evidence of infarction. Here we describe the case of an 11-year-old girl suffering from migraine without aura since the age of four. She e...

The authors describe a patient who developed chronic paroxysmal hemicrania (CPH) in close temporal relationship to a head injury. The subsequent attacks of CPH were associated with a typical migrainous sensory and motor aura. Administration of indomethacin 75 mg daily resulted in isolated occurrence of autonomic and aura symptoms in the absence of pain symptoms. The patient became completely as...

Migraine has been traditionally considered a nonprogressive, paroxysmal disorder with no brain abnormalities between attacks. We used diffusion tensor imaging to examine interictal diffusion properties of the brains of migraineurs with aura, migraineurs without aura and matched healthy controls. Areas of lower fractional anisotropy were present in migraineurs along the thalamocortical tract. In...

BACKGROUND AND PURPOSE Our aim in this study was to compare headache-free and spontaneous migraine measurements of blood flow velocity and the pulsatility index in the anterior cerebral artery, middle cerebral artery, and posterior cerebral artery. METHODS Thirty-one patients (nine having experienced migraine with aura and 22 migraine without aura) were studied in headache-free periods and du...

Most studies of Aurora A (AurA) describe it as a mitotic centrosomal kinase. However, we and others have recently identified AurA functions as diverse as control of ciliary resorption, cell differentiation, and cell polarity control in interphase cells. In these activities, AurA is transiently activated by noncanonical signals, including Ca(2+)-dependent calmodulin binding. These and other obse...

Tissue homeostasis requires accurate control of cell proliferation, differentiation and chromosome segregation. Drosophila sas-4 and aurA mutants present brain tumours with extra neuroblasts (NBs), defective mitotic spindle assembly and delayed mitosis due to activation of the spindle assembly checkpoint (SAC). Here we inactivate the SAC in aurA and sas-4 mutants to determine whether the genera...
