A multidisciplinary collaborative study examining cognition in a large sample of twins is outlined. A common experimental protocol and design is used in The Netherlands, Australia and Japan to measure cognitive ability using traditional IQ measures (i.e., psychometric IQ), processing speed (e.g., reaction time [RT] and inspection time [IT]), and working(More)
We report a high-quality draft sequence of the genome of the horse (Equus caballus). The genome is relatively repetitive but has little segmental duplication. Chromosomes appear to have undergone few historical rearrangements: 53% of equine chromosomes show conserved synteny to a single human chromosome. Equine chromosome 11 is shown to have an evolutionary(More)
1. Prestriate area V4 and the middle temporal area (MT) compose the first stage in which the ventral and dorsal visual cortical pathways are segregated. To better known the functional dichotomy between the two pathways at this level, we recorded cell responses from V4 and MT using anesthetized, immobilized macaque monkeys and compared the selectivity for(More)
In order to control dispersion and dispersion slope of indexguiding photonic crystal fibers (PCFs), a new controlling technique of chromatic dispersion in PCF is reported. Moreover, our technique is applied to design PCF with both ultra-low dispersion and ultra-flattened dispersion in wide wavelength range. A full-vector finite element method with(More)
The potentiating effect of low doses of sigma ligands on the N-methyl-D-aspartate (NMDA)-induced excitation of pyramidal CA3 dorsal hippocampal neurons has recently been reported. In the present study, we investigated behavioral effects relevant to these findings in the experimental amnesia induced by the non-competitive NMDA antagonist, dizocilpine(More)
We present an analysis of atmospheric neutrino data from a 33.0 kiloton-year (535-day) exposure of the Super{Kamiokande detector. The data exhibit a zenith angle dependent decit of muon neutrinos which is inconsistent with expectations based on calculations of the atmospheric neutrino ux. Experimental biases and uncertainties in the prediction of neutrino(More)
Agricultural production is sensitive to weather and thus directly affected by climate change. Plausible estimates of these climate change impacts require combined use of climate, crop, and economic models. Results from previous studies vary substantially due to differences in models, scenarios, and data. This paper is part of a collective effort to(More)
BACKGROUND Descending necrotizing mediastinitis resulting from oropharyngeal abscess, is a serious, life-threatening infection. Exisiting strategies for surgical management, such as transcervical mediastinal drainage or aggressive thoracotomic drainage, remain controversial. METHODS Four patients, (three males and one female) were treated for descending(More)
The histological variability of solitary fibrous tumors may contribute to the difficulty in diagnosing these neoplasms, especially when they arise in extrathoracic sites. Like intrathoracic lesions, the behavior of extrathoracic solitary fibrous tumors is currently unpredictable because these types of tumor have only recently been recognized. This study(More)
To investigate the toxicity of beta-amyloid protein which consisted of senile plaques of Alzheimer's disease (AD), this was infused into cerebral ventricle for 14 days by using mini-osmotic pump. The performance of the water maze task in beta-amyloid protein-treated rats was impaired. Choline acetyltransferase activity significantly decreased in the frontal(More)
