Transient absorption spectra in the Soret region have been measured following the photolysis of human MbCO in 75%(w/w) glycerokwater at 250,270, and 290 K. The peak of the transient difference spectrum near 436 nm shifts from low to high energy on the nanosecond time scale. The spectral changes are quantitatively analyzed using an approach based on singular value decomposition, and the results ...

Polar regions are shown to mediate a strong coupling between polarization and strain in the paraelectric phase of the mixed ferroelectric K12xLixTaO3 ~KLT! and KTa12xNbxO3 resulting in a field-induced piezoelectric response. The coupling is shown to result in a resonance in the dielectric spectrum of the crystals. In KLT, polar nanoregions can reorient via 180° ~p relaxation! or 90° ~p/2 relaxa...

In this article, a framework for the joint modelling of default and recovery risk in a portfolio of credit risky assets is presented. The model especially accounts for the correlation of defaults on the one hand and correlation of default rates and recovery rates on the other hand. Nested Archimedean copulas are used to model different dependence structures. For the recovery rates a very flexib...

– Molecular dynamics simulations of a Lennard-Jones binary mixture confined in a disordered array of soft spheres are presented. The single particle dynamical behavior of the glass former is examined upon supercooling. Predictions of mode coupling theory are satisfied by the confined liquid. Estimates of the crossover temperature are obtained by power law fit to the diffusion coefficients and r...
