Interhemispheric cooperation can be indicated by enhanced performance when stimuli are presented to both visual fields relative to one visual field alone. This "bilateral gain" is seen for words but not pseudowords in lexical decision tasks, and has been attributed to the operation of interhemispheric cell assemblies that exist only for meaningful words with acquired cortical representations. R...

Extension deficit builds up over centuries at divergent plate boundaries and is recurrently removed during rifting events, accompanied by magma intrusions and transient metre-scale deformation. However, information on transient near-field deformation has rarely been captured, hindering progress in understanding rifting mechanisms and evolution. Here we show new evidence of oblique rift opening ...

BACKGROUND Rift Valley fever virus (RVFV) is a mosquito-borne pathogen causing an important disease in ruminants often transmitted to humans after epizootic outbreaks in African and Arabian countries. To help combat the spread of the disease, prophylactic measures need to be developed and/or improved. METHODOLOGY/PRINCIPAL FINDINGS In this work, we evaluated the immunogenicity and protective ...

Rift Valley fever is a vector-borne zoonotic disease which causes high morbidity and mortality in livestock. In the event Rift Valley fever virus is introduced to the United States or other non-endemic areas, understanding the potential patterns of spread and the areas at risk based on disease vectors and hosts will be vital for developing mitigation strategies. Presented here is a general netw...

Water samples from 1286 boreholes from different parts of Kenya were analysed for their fluoride concentrations. The majority of the samples (61.4%) had fluoride ion concentrations above 1.0 parts per million, whilst 19.5% had above 5.0 ppm. Excess levels of fluoride were found to occur in most parts of the country, especially in the Nairobi, Rift Valley, Eastern and Central Provinces which con...

Rift Valley fever virus (RVFV) is a mosquito-borne Phlebovirus that causes periodic outbreaks of animal and human disease in Africa and the Arabian Peninsula. On the basis of its many competent vectors, its potential for aerosol transmission, and its progressive spread from East Africa to neighboring regions between 1950 and 2000, RVFV is ranked as a high-priority, emerging health threat for hu...

The antigenic relationship of the 31 currently recognized phlebotomus fever group viruses was examined by plaque reduction neutralization test. Although some low-level 0cross-neutralization was observed, each of the viruses was easily differentiated by this method. Rift Valley fever virus was shown to be antigenically related to Candiru, Frijoles, Karimabad and Punta Toro viruses. Naples, Tehra...

For years now, virtual reality devices have been applied in the field of vision science in an attempt to improve our understanding of perceptual principles underlying the experience of self-motion. Some of this research has been concerned with exploring factors involved in the visually-induced illusory perception of self-motion, known as vection. We examined the usefulness of the cost-effective...
