New Paper Published in Nature Communications titled, “Exact exchange-correlation potentials from ground-state electron densities”
Published titled Exact potentials electron densities
2019/10/10
The quest for accurate exchange-correlation functionals has long remained a grand challenge in density functional theory (DFT), as it describes the many-electron quantum mechanical behavior through a ...
Correlation between wheat starch annealing conditions and retrogradation during storage
annealed starch degree of retrogradation X-ray diffraction differential scanning calorimetry
2016/2/23
The effects of annealing conditions on the degree of retrogradation (DR) in wheat starch were analysed by differential scanning calorimetry (DSC) and X-ray diffraction (XRD). Three annealing parameter...
Cross-correlation of quality parameters of musts and wines enriched with lignans
hydroxymatairesinol (HMR) enrichment of must and wine correlations antioxidant activity total polyphenol concentration consumer acceptability
2016/2/23
Hydroxymatairesinol (HMR) is the main lignan found in spruce knots. This lignan has been used for enrichment of musts and wines. Quality parameters of these products have been studied for several year...
Multivariate Regression Shrinkage and Selection by Canonical Correlation Analysis
Adaptive Lasso Canonical Correlation Analysis Multivariate Regression
2016/1/25
The problem of regression shrinkage and selection for multivariate regression is considered. The goal is to consistently identify those variables relevant for regression. This is done not only for pre...
Static program checking tools can find many serious bugs in software, but due to analysis limitations they also frequently emit false error reports. Such false positives can easily render the error ch...
Coalition-Proofness and Correlation with Arbitrary Communication Possibilities
Coalition-Proofness Correlation Arbitrary Communication Possibilities
2015/7/21
The ability of the members of a coalition to communicate secretly determines whether the coalition can coordinate to deviate from a proposed strategy and thus affects which strategies are ‘‘coalition ...
A negative correlation between mercury content in muscle and body weight in carp from uncontaminated ponds
Cyprinus carpio total mercury sediment
2015/5/18
The relationship between body weight and total mercury content in the muscle of common carp (Cyprinus carpio) from 13 uncontaminated ponds in South and West Bohemia was investigated. In total, 215 thr...

Objectives. To assess the association between scores on the Health Sciences Reasoning Test (HSRT) and pharmacy student admission variables.
Methods. During the student admissions process, cognitive d...
Correlation between the Degree of Hydrolysis and the Peptide Profile of Whey Protein Concentrate Hydrolysates: Effect of the Enzyme Type and Reaction Time
Hydrolysis Peptide Profile
2016/6/2
The use of protein hydrolysates for the development of new food products requires their prior characterization including the determination of the degree of hydrolysis (DH) and the distribution of pept...
Analysis of elliptical copula correlation factor model with Kendall's tau
Elliptical copula correlation matrix factor model Kendall’s tau nuclear norm penalty oracle inequality primal-dual certificate
2013/6/14
We study a factor model for the correlation matrix $\Sigma\in\RR^{d\times d}$ of an elliptical copula. The correlations are connected to Kendall's tau and a natural estimation procedure is to plug-in ...
