Initial investigations of the cerebellar microcircuit inspired the Marr-Albus theoretical framework of cerebellar function. We review recent developments in the experimental understanding of cerebellar microcircuit characteristics and in the computational analysis of Marr-Albus models. We conclude that many Marr-Albus models are in effect adaptive filters, and that evidence for symmetrical long-te
This review explores the social causes and psychological and organizational consequences of the criminalization of human error in aviation and healthcare. Increasing prevalence of criminal prosecution is seen as a threat to the health and safety of employees and entire safety-critical systems in many industries, but initiatives to counter or mitigate the trend are local and haphazard. Social cause
Background: Acetyl Coenzyme A carboxylase beta (ACACB) is the rate-limiting enzyme in fatty acid oxidation, and continuous fatty acid oxidation in Acacb knock-out mice increases insulin sensitivity. Systematic human studies have not been performed to evaluate whether ACACB variants regulate gene expression and insulin sensitivity in skeletal muscle and adipose tissues. We sought to determine wheth
The purpose of this article is to examine the impact of organisational structure and hoteliers’ risk proclivity on innovativeness in the context of the Japanese hotel industry. Survey questionnaires were used to collect relevant data from 115 hotels in Japan. Using a multiple regression analysis, the antecedents of innovativeness in the hotel industry are been examined. The findings are mixed with
In the intentional-expressive approach, a development within the phenomenographic tradition, an alternative view of the role of language is adopted. The approach focuses the learner's use of expressions and intended meanings, in relation to his/her conception of a phenomenon. The article presents empirical findings from a study made at a university of technology using a special dialogue structure.
Polarimetric radar observations of deep convective storms frequently reveal columnar enhancements of differential reflectivity Z(DR). Such "Z(DR) columns" can extend upward more than 3 km above the environmental 0 C level, indicative of supercooled liquid drops being lofted by the updraft. Previous observational and modeling studies of Z(DR) columns are reviewed. To address remaining questions, th
There are emerging data to support a role for genetic and immune-related factors in the pathogenesis of lymphoplasmacytic lymphoma/Waldenstrom's macroglobulinemia. In this article, we review our recently published, large, population-based studies using data from Sweden and from United States veterans and propose mechanisms and pathways underlying our observations. We also discuss future directions
Background: Biomass fuel smoke exposure contributes to respiratory infections in childhood, but its association with asthma has not been established. We studied the relationship of biomass fuel use with asthma symptoms and lung function in Nigerian children. Methods: A cross-sectional study was performed in 299 village children aged 5-11 years in North Central Nigeria. Data were collected regardin
In the honeybee Apis mellifera, the bacterial gut community is consistently colonized by eight distinct phylotypes of bacteria. Managed bee colonies are of considerable economic interest and it is therefore important to elucidate the diversity and role of this microbiota in the honeybee. In this study, we have sequenced the genomes of eleven strains of lactobacilli and eria isolated from the honey
Single-crystal neutron diffraction reveals two distinct components to the magnetic ordering in geometrically frustrated SrEr2O4. One component is a long-range ordered k = 0 structure which appears below T-N = 0.75 K. Another component is a short-range incommensurate structure which manifests itself by the presence of a strong diffuse scattering signal. On cooling from higher temperatures down to 0
The clinical performance of two nucleic acid amplification assays targeting the cryptic plasmid and two assays targeting rRNA molecules in Chlamydia trachomatis was examined. First-catch urine samples from Malmoe, Sweden, were tested for C. trachomatis with the Abbott real-time PCR assay m2000 and an in-house PCR for the new variant strain of C. trachomatis with a deletion in the cryptic plasmid.
Annually laminated (varved) sediments from the River Angermanalven, mid-central Sweden, have been used to construct an annual 2000-year long record of varve thickness. Maximum daily annual discharge and mean varve thickness for the years 1909-1971 are significantly correlated (r = 0.87). A relationship between maximum daily annual discharge for the observed period (1909-1971) and varve thickness w
Despite their success in different segments of the food industry, membranes are not well-established in the beet and cane sugar industry. A comprehensive overview on the potential applications of membranes in both the beet and cane sugar industry is given. The part on the beet sugar industry focuses on pulp press water recycling, pectin production from beet pulp, beet juice purification, demineral
First, in the absence of pair correlation the properties of one-particle orbits of neutrons in nuclei close to the neutron drip line are briefly reviewed for both weakly bound neutrons and the neutrons in the continuum. The low-lying states in the continuum, which are close to the Fermi level, are of immediate importance for pair correlation and deformations of those nuclei. Then, the Hartree-Fock
The notion of organizations as learning entities has gained considerably in popularity over the last decade, and is now regarded an important issue both theoretically and in practice. Many organizational activities and events have been referred to as learning phenomena, and learning theory is being applied to increasingly varied and complex settings of organizational life. This divergence would su
Various aspects of the lichen genus Xanthoparmelia have been investigated using ITS rDNA sequences. The delimitation of the genus and phylogeographic trends within the genus are reviewed. Three south African genera, Almbornia, Namakwa and Xanthomaculina, are synonymized with Xanthoparmelia. The transfer of Xanthoparmelia peruviensis to Psiloparmelia is strongly supported by a bootstrap analysis. T
