LUC‐CNDO computation scheme and its valence theory applications are discussed. Electronic structure calculations of well‐known semiconductors Cu2O are reviewed. The parameters of CNDO scheme for copper–oxygen compounds are calibrated using the results of Cu2O band theory calculations and experimental data.
The crystalline structure of copper‐oxygen compounds with copper atom in the oxidation states I, II, and III is reviewed. A calculation is made of the electronic structure of the row of crystals with copper‐oxygen bonding. It is shown that the covalence effects are essential for copper oxide compounds containing copper atoms in oxydation states CuII and CuIII LUC‐CNDO calculations of La2CuO4 and Y
AIMS: Failure of healing is a well-known problem after repair of the rotator cuff. This study aimed to investigate if early repair of trauma-related full-thickness rotator cuff tears (FTRCTs) could prevent this failure. PATIENTS AND METHODS: In this prospective trial, 62 consecutive patients (14 women (23%), 48 men (77%); median age 61 years (interquartile range (IQR) 54 to 65)) with trauma-relate
Different approaches to the theoretical study of the local centres in solids are discussed. Particular attention is paid to the embedded-cluster models. There are given the mathematical formulation, the computational scheme and applications for some local centres on/in graphite monolayers of the moderately large embedded cluster and the large-unit-cell-embedded-cluster (LUC-EC) models. It is shown
Objective Blood type A antigen on porcine aortic bioprostheses might initiate an immune reaction leading to an increased frequency of structural valve deterioration in patients with blood type B or O. The aim was to analyse the association between ABO blood type and porcine bioprosthetic aortic valve degeneration. Design Observational nationwide cohort study. Setting Swedish population-based study
Performing PET imaging during ongoing radionuclide therapy can be a promising method to follow tumor response in vivo. However, the high therapeutic activity can interfere with the PET camera performance and degrade both image quality and quantitative capabilities. As a solution, low-energy photon emissions from the therapeutic radionuclide can be highly attenuated, still allowing sufficient detec
National virtual multidisciplinary team meetings have been established in Swedish cancer care in response to centralized treatment of rare cancers. Though national meetings grant access to a large multidisciplinary network, we hypothesized that video-based meetings may challenge participants’ contributions to the case discussions. We investigated participants’ views and used observational tools to
This volume is a collection of articles dealing with a question of Jewish involvement in the interfaith and intercultural dialogue in the postwar Europe, Israel and the United States. Jewish relation to alterity is seen from a few different methodological standpoints: historical, sociological, theological and literary.
We construct a model based on the electroweak gauge group SU(2)L×SU(2)R×U(1)B-L augmented by an S3 symmetry. We assign nontrivial S3 transformation properties to the quarks, and consequently we need two scalar bidoublets. Despite the extra bidoublet, we have only six Yukawa couplings thanks to the discrete symmetry. Diagonalization of the quark mass matrices shows that at the leading order only th
In a truly model-independent approach, we reexamine a minimal extension of the Standard Model (SM) through the introduction of an additional U(1) symmetry leading to a new neutral gauge boson (Z′), allowing its kinetic mixing with the hypercharge gauge boson. An SM neutral scalar is used to spontaneously break this extra symmetry, leading to the mass of the Z′. Except for three right-handed neutri
