An earlier proposed propagator method for the treatment of molecular ionization is tested in first applications. The method referred to as the non-Dyson third-order algebraic-diagrammatic construction [nD-ADC(3)] approximation for the electron propagator represents a computationally promising alternative to the existing Dyson ADC(3) method. The advantage of the nD-ADC(3) scheme is that the (N+/...

The influence of strong electron-electron interactions and Wigner-molecule (WM) formation on the spectra $2e$ singlet-triplet double-dot Si qubits is presented based a full configuration interaction (FCI) approach that incorporates valley degree freedom (VDOF) in context continuous (effective mass) description semiconductor materials. Our FCI treats VDOF as an isospin addition to regular spin. ...

We investigate the spectral shape, the anisotropy of the wave vector distributions and the anisotropy of the amplitudes of the magnetic fluctuations in the Earth’s magnetosheath within a broad range of frequencies [10−3, 10] Hz which corresponds to spatial scales from ∼ 10 to 10 km. We present the first observations of a Kolmogorov-like inertial range of Alfvénic fluctuations δB ⊥ ∼ f−5/3 in th...

Finding the most interesting correlations in a collection of items is essential for problems in many commercial, medical, and scientific domains. Much previous research focuses on finding correlated pairs instead of correlated itemsets in which all items are correlated with each other. Though some existing methods find correlated itemsets of any size, they suffer from both efficiency and effect...

OBJECTIVE Obesity, insulin resistance, and weight loss have been associated with changes in hypothalamic-pituitary-adrenal (HPA) axis. So far, no conclusive data relating to this association are available. In this study, we aim to investigate the effects of massive weight loss on cortisol suppressibility, cortisol-binding globulin (CBG), and free cortisol index (FCI) in formerly obese women. ...

BACKGROUND Hong Kong has a tripartite healthcare system, where western medicine provided in both public and private sectors coexist with Chinese medicine practice. The purpose of this study is to measure fragmentation of ambulatory care experienced by the non-institutionalized population aged 15 and over in such a tripartite system, thus shed light on the ongoing primary care reform. METHODS ...

OBJECTIVE This study aims at developing and introducing a new algorithm, called direct causal learner (DCL), for learning the direct causal influences of a single target. We applied it to both simulated and real clinical and genome wide association study (GWAS) datasets and compared its performance to classic causal learning algorithms. METHOD The DCL algorithm learns the causes of a single t...
