The production of high quality animations which feature compelling lighting effects is computationally a very heavy task when traditional rendering approaches are used where each frame is computed separately. The fact that most of the computation must be restarted from scratch for each frame leads to unnecessary redundancy. Since temporal coherence is typically not exploited, temporal aliasing ...

People with eating disorders (EDs) are reported to have set-shifting difficulties, strengths in local or detailed information processing and weak central coherence or global processing. This study aimed to explore the validity of a novel, brief, global, neurocognitive task which has not previously been utilised in an ED population, the Navon Figures Task (NFT). The NFT is substantially quicker ...

Anomic aphasia is a disturbance affecting lexical retrieval. Nonetheless, persons with this disorder may also experience difficulties in the construction of coherent narratives. Whether this symptom is a sign of a macrolinguistic difficulty per se or reflects the lexical disorder is still an open debate. In order to analyze the effect of the lexical impairment on macrolinguistic processing, we ...

The ability to interactively render dynamic scenes with global illumination is one of the main challenges in computer graphics. The improvement in performance of interactive ray tracing brought about by significant advances in hardware and careful exploitation of coherence has rendered the potential of interactive global illumination a reality. However, the simulation of complex light transport...

Fragment reconstruction is a cache coherence protocol for transactional storage systems based on global caching in a network of workstations. It supports ne-grained sharing and works in the presence of object-based concurrency control algorithm. When transactions commit new versions of objects, stale cached copies of these objects get invalidated. Therefore, pages in a client's cache may become...

Early visual motion signals are local and one-dimensional (1-D). For specification of global two-dimensional (2-D) motion vectors, the visual system should appropriately integrate these signals across orientation and space. Previous neurophysiological studies have suggested that this integration process consists of two computational steps (estimation of local 2-D motion vectors, followed by the...

Frith and Happé (1994) argue that individuals with autism exhibit ‘weak central coherence’: an inability to integrate elements of information into coherent wholes. Some authors have speculated that a higher-level impairment might be present in the magnocellular visual pathway in autism, and furthermore, that this might account for weak central coherence, at least at the visuospatial level. We a...

The present study aimed at exploring how two main primarily semantic factors of discourse comprehension, namely global coherence and amount of information cumulated across a passage, may impact on the sentential syntactic processing. This was measured in two event-related brain potentials (ERP) to grammatical (morphosyntactic) violations: anterior negativities (LAN) and posterior positivities (...
