Cell division entails a marked reorganization of the microtubule network to form the spindle, a molecular machine that ensures accurate chromosome segregation to the daughter cells. Spindle organization is highly dynamic throughout mitosis and requires the activity of several kinases and complex regulatory mechanisms. Aurora A (AurA) kinase is essential for the assembly of the metaphase bipolar...

The sequences of aura sensations in 143 patients with complex partial seizures, were analysed with special emphasis on aphasic symptoms. Anxiety, epigastric sensation and visual hallucination were experienced early in the course of the aura, while illusion of familiarity and aphasia occurred late in the course of the aura. Three groups of interconnections of aura sensations were found which cor...

Walter Benjamin is best known for his essay ‘The Work of Art in the Age of Mechanical Reproduction’, (Benjamin, 1968b) in which he argues that film and other mechanical technologies are destroying the aura that had belonged to traditional art. In this article we apply Benjamin’s concept of aura to new (digital) media, and in particular to ‘mixed reality’, a group of technologies that blend comp...

Gibbs random eld (GRF) models and co-occurrence statistics are typically considered as separate but useful tools for texture discrimination. In this paper we show an explicit relationship between co-occurrences and a large class of GRF's. This result comes from a new framework based on a set-theoretic concept called the \aura set" and on measures of this set, \aura measures". This framework is ...

Neurologic symptoms are a prominent and often disturbing component of the migraine syndrome in many patients. Collectively termed "aura," migraine-related neurologic symptoms include visual, sensory, language, and motor disturbance. They occur in about one quarter of migraine patients, are classically transient, and are thought to occur as the result of cortical phenomena. Recently, motor sympt...

Aura is an evolving software architecture and “real-time middleware” implementation that has been in use since 1994. As an integrated solution to many problems encountered in the design of distributed, real-time, interactive, multimedia programs, experience with Aura offers lessons for designers. By identifying common problems and evaluating how different systems solve them, we hope to learn ho...
