Adaptive leaky integrator models of cerebellar Purkinje cells can learn the clustering of temporal patterns
(1999-06)
We have shown previously that the metabotropic glutamate receptor signalling network in a cerebellar Purkinje cell can implement adaptive postsynaptic delays. Here we present a leaky integrator version of the Purkinje cell ...
Design principles from traditional mountain irrigation systems (bisses) in the Valais, Switzerland
(1999-05)
The bisses are a traditional mountain irrigation system constructed in response to periodic water deficit during the summer months in the Valais canton of Switzerland. The origins of the bisse system can be traced back to ...
The potential magnetic field of AB Doradus: comparison with Zeeman-Doppler images
(1999-05-01)
We have modelled the global-magnetic-field topology of the young, rapidly rotating KO dwarf AB Dor by assuming that the field is potential and using as a boundary condition Zeeman-Doppler images of the surface radial field ...
The astrophysical r-process : A comparison of calculations following adiabatic expansion with classical calculations based on neutron densities and temperatures
(1999-05-01)
The rapid neutron-capture process (r-process) encounters unstable nuclei far from beta-stability. Therefore its observable features, like the abundances, witness (still uncertain) nuclear structure as well as the conditions ...
A meta-analysis of mass-media tests of extrasensory perception
(1999-05)
Some scientists have argued that recent meta-analyses of many different types of parapsychological study suggest that extrasensory perception (ESP) might exist, albeit as a small effect. Large-scale ESP experiments conducted ...
Implications of land use change for the production of plant biomass in densely populated Sahelo-Sudanian shrub-grasslands in north-east Nigeria.
(1999-05)
The production of plant biomass on small farms and in woodland in densely populated locations in the Nigerian Sahelo-Sudan is estimated in order to test the hypothesis that conversion of land from natural vegetation to ...
Microphysical particle parameters from extinction and backscatter lidar data by inversion with regularization: theory
(1999-04-20)
A method is proposed that permits one to retrieve physical parameters of tropospheric particle size distributions, e.g., effective radius, volume, surface-area, and number concentrations, as well as the mean complex ...
Microphysical particle parameters from extinction and backscatter lidar data by inversion with regularization: simulation
(1999-04-20)
A sensitivity study with an inversion scheme that permits one to retrieve physical parameters of tropospheric particle size distributions, e.g., effective radius, volume, surface-area, and number concentrations, as well ...
Characterization of progressive motor deficits in mice transgenic for the human Huntington's disease mutation
(1999-04-15)
Transgenic mice expressing exon 1 of the human Huntington's disease (HD) gene carrying a 141-157 CAG repeat (line R6/2) develop a progressive neurological phenotype with motor symptoms resembling those seen in HD. We have ...
