General formalism of absorption and emission spectra, and of radiative and nonradiative decay rates are derived using a thermal vibration correlation function formalism for the transition between two adiabatic electronic states in polyatomic molecules. Displacements, distortions, and Duschinsky rotation of potential energy surfaces are included within the framework of a multidimensional harmoni...

The structure of doped BiMnO3 was studied using synchrotron x-ray powder diffraction. The dopants included isovalent magnetic and non-magnetic ions in the magnetic Mn sublattice (BiMn1-xMx O3 with M=Cr, Fe and Ga), isovalent ions in the Bi sublattice (Bi0.9La0.1MnO3) and isovalent self-dopants (Bi0.95MnO2.925). The results indicate that at low doping levels, the orbitally ordered structure (C2/...

The evolution of hubs etabolic networks rely heavily on a few crucial metabolic hubs, such as ATP, NADH, and glutamate, that are widely used in many cellular biochemical reactions. In contrast to hubs, most other metabolites each participate in only a few reactions. Now, research from Thomas Pfeiffer, Orkun Soyer, and Sebastian Bonhoeffer (ETH Zürich, Switzerland) shows that hubs are the natura...

Recently, Pfeiffer and colleagues have published protocols that allow the isolation of human hepatocytes and non-parenchymal liver cells from the same donor (Pfeiffer et al., 2014). Cell isolation is performed with resected liver tissue, usually obtained from hepatectomy because of metastasis from colon cancer. Human liver cells are initially isolated by the conventional two-step EDTA/ collagen...

A cluster Monte Carlo algorithm for the Ashkin-Teller (AT) model is constructed according to the guidelines of a general scheme for such algorithms. Its dynamical behaviour is tested for the square lattice AT model. We perform simulations on the line of critical points along which the exponents vary continuously, and find that critical slowing down is significantly reduced. We find continuous v...

Mesoporous rutile TiO(2) nanoneedles have been successfully synthesized using a reverse microemulsion-mediated sol-gel method at room temperature. The materials were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and the Bruauner-Emmet-Teller (BET) adsorption method, and their electrochemical properties were investigated by galvanostatic charge and discharge t...

Nehmen uns Roboter die Arbeit weg? Wer diese Frage stellt, missversteht Digitalisierung - sie ist keine industrielle Revolution mit anderen Mitteln. Sabine Pfeiffer sucht nach dem wirklich Neuen hinter der und digitalen Kapitalismus. Sie stellt in ihrer Analyse Marx'schen Begriff Produktivkraft Idee Distributivkraft zur Seite. Von Plattformökonomie bis künstlichen Intelligenz wird damit versteh...
