BackgroundLoss of high-molecular-weight multimers (HMWMs) of von Willebrand factor (vWF) occurs due to high shear stress in patients with aortic stenosis. As symptoms of aortic stenosis occur during exercise, measurement of vWF during exercise might

First-principles calculations of the electronic and spatial structures of the Ba1−x LaxF2+x system within the supercell model
Autor: A. B. Sobolev, J. Andriessen, A. Yu. Kuznetsov, C.W.E. van Eijk, A. N. Varaksin
Publikováno v: Physics of the Solid State. 45:838-844
The electronic and spatial structures of the La impurity in BaF2 are investigated using the ab initio method of linear combinations of atomic orbitals based on the Hartree-Fock approximation in the supercell model. Calculations are performed using th

4 f n−1 5 d centroid shift in lanthanides and relation with anion polarizability, covalency, and cation electronegativity
Autor: C.W.E. van Eijk, Pieter Dorenbos, J. Andriessen
Publikováno v: Journal of Solid State Chemistry. 171:133-136
Data collected on the centroid shift of the 5 d -configuration of Ce 3+ in oxide and fluoride compounds were recently analyzed with a model involving the correlated motion between 5 d -electron and ligand electrons. The correlation effects are propor

Hartree–Fock calculation of BaF2:La systems
Autor: A. Yu. Kuznetsov, J. Andriessen, C.W.E. van Eijk, A. B. Sobolev
Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 486:385-389
We present the results of an investigation of the electron structures of BaF 2 , LaF 3 and BaF 2 :La crystals. The effects of lattice polarization and relaxation were considered. The calculations were performed using the C rystal 98 code, the molecul

Explanation of the T- and X-line components of the emission of ns2 impurity ions in alkali halides by lattice relaxation studies
Autor: J. Andriessen, C.W.E. van Eijk
Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 486:403-407
Accurate lattice relaxation studies were performed on the impurity centres Ga, In and Tl in FCC KCl, when these ions are excited from the ground ns 2 state to the triplet nsnp state. Using HF-LCAO as the basic model for the electronic structure a sat

The centroid shift of the 5d levels of Ce3+ with respect to the 4f levels in ionic crystals, a theoretical investigation
Autor: C.W.E. van Eijk, Pieter Dorenbos, J. Andriessen
Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 486:399-402
The centroid shifts of the 5d level of Ce 3+ in BaF 2 , LaAlO 3 and LaCl 3 have been calculated using the ionic cluster approach. By applying configuration interaction as extension of the basic HF-LCAO approach the dynamical polarization contribution

Lattice relaxation of luminescence centres of theX-line emission ofns2impurity ions in alkali halides; anomalous geometry of the impurity centre in the excitednsnp state
Autor: C.W.E. van Eijk, M. Marsman, J. Andriessen
Publikováno v: Journal of Physics: Condensed Matter. 13:10507-10515
Clear evidence was found that in the active centre from which the X-line emission of ns2 impurities in alkali halides originates the excited impurity ion is statically displaced over an anomalously large distance in a direction which depends on the l
