The present study was designed to examine the cerebral hemispheric differences in memory of positive, negative and non-emotional words using a new method of successive presentation to each visual half-field in which perception of each item was nearly perfect thereby allowing laterality differences for effects of emotion on memory to emerge unconfounded by perception (Experiment 1). This procedu...

The Photoexcited carrier lifetime (τ) and peak to valley transmission difference (ΔTp-v) in direct and indirect band gap crystals has been investigated by the use of single beam open and closed aperture z-scan technique using frequency doubled Nd:YAG laser. The peak to valley transmission difference (ΔTp-v) is found to be of the order of 10-2 in case of direct band gap crystals and of the order...

Understanding the syntax of an undeciphered writing is a significant challenge. This can provide important clues to the nature of writing and guide potential decipherments. Here we evaluate a set of computational tools that can help us address this problem. We show that significant aspects of the writing can be inferred through this approach without making any assumption about the underlying co...

Introduction The Moab Slickrock Trail was the first trail designated primarily for mountain bike use and is one of the most popular mountain bike trails in the world. It was established as a motorcycle trail in 1969, but by the mid 1980s, it was primarily used by mountain bikers. The trail is located on a sandstone plateau overlooking the Colorado River, Moab Valley, and Arches National Park. T...

We show why and how the IĪ valley trajectory commonly used in the literature so far is in fact unsatisfactory. A better IĪ valley is suggested. We also give analytic expressions for the multiple instanton-antiinstanton configurations in the pure Yang-Mills theory. These formulas make it possible to go beyond the dilute gas approximation and calculate the multi-body interactions among instantons...

During May-July 2010 in Namibia, outbreaks of Rift Valley fever were reported to the National Veterinary Service. Analysis of animal specimens confirmed virus circulation on 7 farms. Molecular characterization showed that all outbreaks were caused by a strain of Rift Valley fever virus closely related to virus strains responsible for outbreaks in South Africa during 2009-2010.
