We investigated the ability of mutual nonlinear prediction methods to assess causal interactions in short-term cardiovascular variability during normal and impaired conditions. Directional interactions between heart period (RR interval of the ECG) and systolic arterial pressure (SAP) short-term variability series were quantified as the cross-predictability (CP) of one series given the other, an...

Inhalation of the short-lived radon decay products, Po, Pb, Bi/Po, in homes, in the outdoor atmosphere and at work places yield the greatest amount of the natural radiation exposure of the human. In all dosimetric models the dominant parameter related to dose is the activity size distribution of the decay products in the air because the original deposition destination and amount of the inhaled ...

Time-related optimization problems are very hard to solve. Scheduling covers a subcategory of such problems where the goal is to place events in time. The discretization of time triggers a rapid growth of possible placements, leading to large search spaces. While scheduling problems were already computationally solved two decades ago, large real-world sized instances seemed to be out of reach b...

Spiny dogfish shark (Squalus acanthias) lateral and IV choroid plexuses (CPs) are ultrastructurally similar to the corresponding tissues of rat. However, shark IV CP is proportionally larger and easily accessible. Moreover, this epithelial sheet can be halved and studied in Ussing flux chambers. We have used confocal fluorescence microscopy and radiotracer techniques to characterize transepithe...

The synthesis and reactivity of nickel complexes with the [2-(dimethylamino)ethyl]cyclopentadienyl ligand (CpN) are described. The reaction of NiBr2 with CpNLi leads to the new paramagnetic nickelocene derivative (Cp)2Ni (1), which has been characterized by 1H and 13C NMR, elemental analysis, and mass spectroscopy. Synproportionation of this complex with Ni(CO)4 affords quantitatively the dimer...

The CP violation in K and B decays are discussed with the emphasize on the precise prediction for ǫ ′ /ǫ and the new physics effects from a class of models with additional Higgs doublets and fermions. The contributions from standard model with two-Higgs-doublet (S2HDM) to K, B mixing and decays are briefly reviewed. The possible large effects on CP violation in B → φK is discussed in an extende...

The effects of dietary copper (Cu) supplementation in broiler chickens challenged with a single injection of Salmonella typhymurium lipopolysaccharide (LPS) on the antioxidant capacity and plasma levels of ceruloplasmin (Cp) were evaluated. The broiler chickens were provided with a basal diet or diets supplemented with 8 and 50 mg/kg Cu from 1d of age. At 25d of age, 48 chickens with similar bo...
