A computational model with three interacting components for context sensitive reinforcement learning, context processing and automation can autonomously learn a focus attention and a shift attention task. The performance of the model is similar to that of normal children, and when a single parameter is changed, the performance on the two tasks approaches that of autistic children.

The reactive vascular-injuring amino acid homocysteine was measured in plasma samples from 79 well-characterized type 1 diabetic patients and 46 control subjects. Patients with proliferative retinopathy had higher homocysteine levels (15.0 +/- 6.3 mumols l-1; mean +/- SD, p less than 0.001; n = 42) than those with progressive retinopathy during a two-year period (10.4 +/- 1.6 mumols l-1; n = 12),

We report on fabrication of double quantum dots in catalytically grown InAs/InP nanowire heterostructures. In the few-electron regime, starting with both dots empty, our low-temperature transport measurements reveal a clear shell structure for sequential charging of the larger of the two dots with up to 12 electrons. The resonant current through the double dot is found to depend on the orbital cou

To evaluate the large pore radius of the glomerular capillary filter, plasma-to-urine fractional clearances of a number of endogenous proteins were assessed in normal and in nephrotic Wistar rats in which proximal tubular reabsorption had been inhibited using lysine. The proteins studied varied in radius from 16.2 A (Beta 2-microglobulin) to 90 A (alpha 2-macroglobulin). The nephrotic syndrome was

The colorimetric 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was standardized for direct detection of rifampin-resistant Mycobacterium tuberculosis in sputum samples. The sensitivity and specificity of the direct MTT assay matched those of the standard indirect susceptibility assay on 7H10 medium, and interpretable results were obtained for 98.5% of the samples within

Renal cell carcinoma (RCC) is the most prevalent cancer of the kidney. In human RCC cells, we recently showed that insulin-like growth factor I (IGF-I) has growth-promoting effects regulated by IGF-binding protein 3 (IGFBP-3). In this study, the analysis was expanded to include the interaction between the IGF and transforming growth factor-beta (TGF-beta) systems in the human RCC cells Caki-2 (fro

Yoghurts were produced with 24 different cultures differing in their ability to produce exopolysaccharides (EPS). Rheological and sensory analyses showed large differences in texture properties in the yoghurt samples. EPS production was found to have a major effect oil the texture properties, but varying textures within the EPS +/- groups were also found. Yoghurts fermented with EPS-producing cult

The aim of this report is to study how the authorities in twelve Swedish municipalities consider social vulnerability in disasters. The study is based on telephone interviews with ten officials responsible for safety and risk analysis and with ten officials responsible for social and psychological support after disasters. Three group interviews about the support for affected citizens after the sto

Moments of the hadronic invariant mass and of the lepton energy spectra in semileptonic B decays have been determined with the data recorded by the DELPHI detector at LEP. From measurements of the inclusive b-hadron semileptonic decays, and imposing constraints from other measurements on b- and c-quark masses, the first three moments of the lepton energy distribution and of the hadronic mass distr

PURPOSE. To characterize the spectrum of mutations in the OPA1 gene in a large international panel of patients with autosomal dominant optic atrophy (adOA), to improve understanding of the range of functional deficits attributable to sequence variants in this gene, and to assess any genotype-phenotype correlations. METHODS. All 28 coding exons of OPA1, intron-exon splice sites, 273 bp 5' to exon 1

A search for pair-produced charged Higgs bosons was performed in the high energy data collected by the DELPHI detector at LEP II at centre-of-mass energies from 189 GeV to 202 GeV. The three different final states, taunutaunu, c (s) over bar(c) over bars and c (s) over bar taunu were considered. New methods were applied to reject wrong hadronic jet pairings and for the tau identification, where a

In this paper we construct quasi-deformations of sl(2) (R) with the Laurent polynomials over the reals as base algebra and general vector fields for sl(2) (R) in the base of the quasi-deformation.

Fiber-reinforced flexible composites are extensively used for different kinds of applications, for example, tubes, drive belts, tires, and coated fabrics. Typical for these materials are matrix materials allowing large strain deformation and reinforcement structures allowing bending. Apart from the tensile strength and limited bending stiffness, damage resistance and ductile-brittle transition cha
