The doping mechanism and realistic Fermi surface (FS) evolution of La2−xSrxCuO4 (LSCO) are modelled within an extensive ab initio framework including advanced band-unfolding techniques. We show that ordinary Kohn-Sham DFT+U can reproduce the observed metal-insulator transition, when not restricted to the paramagnetic solution space. Arcs are self-doped by orbital charge transfer within the Cu-O planes, while the introduced Sr charge is strongly localized. Arc protection and the inadequacy of the rigid-band picture are consequences of a rapid change in orbital symmetry at the Fermi energy: the material undergoes a dimensional crossover along the Fermi surface, between the nodal (2D) and antinodal (3D) regions. In LSCO, this crossover accounts for FS arcs, the antinodal pseudogap, and insulating behavior in c-axis conductivity, all ubiquitous phenomena in high-Tc cuprates. Ligand Coulomb integrals involving out-of-plane sites are principally responsible for the most striking effects observed by ARPES in LSCO.

The main aim of this paper is to examine the influence of bank specific determinants on realization of credit risk in the portfolio of commercial banks in Bosnia and Herzegovina (B&H). This study comprises a sample of seventeen out of twenty eight planned banks that are analyzed over the period of 2002 to 2012. The effect of variations in the determinants of bank credit risk exposure is based on using a multivariate panel regression model. Our empirical results suggest that a significant relationship exists between credit risk and the following variables:[Inefficiency (IE), profitability (ROE), Credit growth (CG) and Deposit rate (DR) while variables Solvency (SR), Loans to deposit ratio (LTD), Market power (MP), profitability (ROA) and Reserve ratio (RR)] are not statistically significant in terms of credit risk.

Probiotics are live microorganisms which administered in adequate quantities have beneficial effects on the health of the host. The word probiotic means “for life”. Probiotics contribute to the microbial balance, protect the body from harmful microorganisms, enhancing the immune system, and play an important role in maintaining oral health. Bacteria are commonly used as probiotics. Dental caries and periodontal disease the most common diseases in oral cavity caused by bacterial activities. Probiotics used in the treatment of oral changes are in the form of lozenges, tablets, capsules, liquids, yogurt and cheese.

When it comes to industrial organizations, current collaboration efforts in software engineering research are very often kept in-house, depriving these organizations of the skills necessary to build independent collaborative research. The current trend, towards empirical software engineering research, requires certain standards to be established which would guide these collaborative efforts in creating a strong partnership that promote independent, evidence-based, software engineering research. This paper examines key enabling factors for an efficient and effective industry-academia collaboration in the software testing domain. A major finding of the research was that while technology is a strong enabler to better collaboration, it must be complemented with industrial openness to disclose research results and the use of a dedicated tooling platform. We use as an example an automated test generation approach that has been developed in the last two years collaboratively with Bombardier Transportation AB in Sweden.
