The partial molar volume, .hivin.V, and the partial sp. vol., .hivin.n, were estd. for more than 25 polyelectrolyte structures. The materials investigated by d. measurements in highly dild. aq. solns. (c < 10-2 monomol/L) included both synthetic polyelectr ...
Chemically zoned FeNi metal grains in the metal-rich chondrites QUE 94411 and Hammadah al Hamra 237 formed by gas-solid condensation in the temperature range from similar to1500 to 1400 K during highly energetic thermal events in the solar nebula. We obser ...
Most mammalian cells have in their plasma membrane at least two types of lipid microdomains, non-invaginated lipid rafts and caveolae. Glycosylphosphatidylinositol (GPI)-anchored proteins constitute a class of proteins that are enriched in rafts but not ca ...
A role for corticosterone in the consolidation of contextual fear conditioning has previously been proposed. In this study, physiological evidence was found to support this view. The extent of conditioned fear and the levels of plasma corticosterone in rat ...
The purpose of this paper is to illustrate a method which can be used to select relevant input variables for non-linear regression. The proposed method is an extension to the concept of SOM such that the linear correlation coefficient is computed over a wh ...
We analyse a model for the development of orientation-selective receptive fields of simple cells in a locally connected network of cortical neurons. The Hebbian learning rule that underlies the development is described by a linear differential equation. Th ...
We analyze a model of navigational map formation based on correlation-based, temporally asymmetric potentiation and depression of synapses between hippocampal place cells. We show that synaptic modification during random exploration of an environment shift ...
An analysis of correlation coefficients for climatological data covering the period 1901-1994 or 1931-1994 for six locations in Switzerland has been made in order to highlight the relationships between temperature, precipitation (rain and snow) and snow in ...
In a survey of cardiovascular risk factors in 185 men and 173 women of a Belgian population group, an independent and highly significant positive correlation was found between the serum concentrations of 25-hydroxyvitamin D3 and apolipoprotein A-I (p less ...
Vertical electric field waveforms of leader-return stroke sequences measured 500 m and 30 m from rocket-triggered lightning are presented. The 500-m data were recorded during the boreal summer of 1986, the 30-m data during the summer of 1991, both at the N ...
