Comparative study of endotoxin-induced hypotension in kininogen-deficient rats with that in normal rats.
Description :
1. The aim of this study was to clarify the role of endogenous bradykinin (BK) in the hypotensive response induced by lipopolysaccharide (LPS) by comparing the degree of hypotension caused by LPS in a strain of specific pathogen-free (SPF) Brown Norway (B/N), kininogen-deficient mutant Katholiek rat...

Subband filling and Mott transition in Ca_{2-x}Sr_xRuO_4
Description :
A new concept is proposed for the paramagnetic metal insulator transition in
the layer perovskite Ca_{2-x}Sr_xRuO_4. Whereas the pure Sr compound is
metallic up to very large Coulomb energies due to strong orbital fluctuations,
structural changes induced by doping with Ca give rise to a interorbit...

An embedding potential definition of channel functions
Description :
We show that the imaginary part of the embedding potential, a generalised
logarithmic derivative, defined over the interface between an electrical lead
and some conductor, has orthogonal eigenfunctions which define conduction
channels into and out of the lead. In the case of an infinitely extended...

Coulomb correlations do not fill the e'_g hole pockets in Na_{0.3}CoO_2
Description :
There exists presently considerable debate over the question whether local
Coulomb interactions can explain the absence of the small e'_g Fermi surface
hole pockets in photoemission studies of Na_{0.3}CoO_2. By comparing dynamical
mean field results for different single particle Hamiltonians and e...

The Mott insulator LaTiO_3 in heterostructures with SrTiO_3 is metallic
Description :
It is shown that LaTiO_3 in superlattices with SrTiO_3 is not a Mott
insulator but a strongly correlated metal. The tetragonal lattice geometry
imposed by the SrTiO_3 substrate leads to an increase of the Ti 3d t2g band
width and a reversal of the t2g crystal field relative to the orthorhombic bul...

Embedding approach for dynamical mean field theory of strongly correlated heterostructures
Description :
We present an embedding approach based on localized basis functions which
permits an efficient application of the dynamical mean field theory (DMFT) to
inhomogeneous correlated materials, such as semi-infinite surfaces and
heterostructures. In this scheme, the semi-infinite substrate leads connect...

Correlation induced spin freezing transition in FeSe: a dynamical mean field study
Description :
The effect of local Coulomb interactions on the electronic properties of FeSe
is explored within dynamical mean field theory combined with finite-temperature
exact diagonalization. The low-energy scattering rate is shown to exhibit
non-Fermi-liquid behavior caused by the formation of local moments...

Coulomb blockade and Kondo effect in the electronic structure of Hubbard molecules connected to metallic leads: a finite-temperature exact-diagonalization study
Description :
The electronic structure of small Hubbard molecules coupled between two
non-interacting semi-infinite leads is studied in the low bias-voltage limit.
To calculate the finite-temperature Green's function of the system, each lead
is simulated by a small cluster, so that the problem is reduced to tha...

Block of pancreatic ATP-sensitive K+ channels and insulinotrophic action by the antiarrhythmic agent, cibenzoline.
Description :
1. We investigated the effect of cibenzoline (a class Ia antiarrhythmic drug) on basal insulin secretory activity of rat pancreatic islets and ATP-sensitive K+ channels (KATP) in single pancreatic beta cells of the same species, using radioimmunoassay and patch clamp techniques. 2. Micromolar cibenz...
