A method to visualize many-body correlations using the information of full wave function is presented. The set nucleon coordinates which maximizes square function, that is, most probable spatial configuration nucleons, visualized. applied Hartree-Fock (HF) and HF+BCS functions $p$- $sd$-shell $N=Z$ even-even nuclei analyze in those systems. It found there are $\alpha$-cluster-like four-body alr...
A rterial stiffness has re-emerged over the past 20 years as an important predictor of cardiovascular outcomes. However, the evidence on the role of arterial stiffness in the development of heart failure (HF) is limited to 2 large studies with some conflicting resulting. Furthermore, both studies lack the distinction between HF phenotypes, which could be associated differently with arterial sti...
Bound energy levels and properties of the Cl(2P)-HF complex were obtained from full three-dimensional (3D) calculations, with the use of the ab initio computed diabatic potential surfaces from the preceding paper and the inclusion of spin-orbit coupling. For a better understanding of the dynamics of this complex we also computed a 2D model in which the HF bond length r was frozen at the vibrati...
ELF/VLF waves can be generated via amplitude modulated HF heating of the auroral electrojet, which turns a patch of ionospheric currents into a radiating antenna. A new, more powerful technique, termed `geometric modulation', involves scanning the HF beam in geometric patterns with no power modulation. Utilizing results obtained from the HAARP facility, we show that geometric modulation enhance...
Depressed contractility of failing myocytes involves a decreased rate of rise of the Ca2+ transient. Synchronization of Ca2+ release from the junctional sarcoplasmic reticulum (SR) is responsible for the rapid rise of the normal Ca2+ transient. This study examined the idea that spatially and temporally dyssynchronous SR Ca2+ release slows the rise of the cytosolic Ca2+ transient in failing feli...
There is evidence that gastrointestinal function adapts in response to a high-fat (HF) diet. This study investigated the hypothesis that an HF diet modifies the acute effects of duodenal lipid on appetite, antropyloroduodenal pressures, plasma CCK and plasma glucagon-like peptide-1 (GLP-1) levels in humans. Twelve healthy men were studied twice in randomized, crossover fashion. The effects of a...
The mechanism of the huge optical recti cation (OR) in asymmetrical quantum wells (AQW) has been investigated at high frequencies (HF) obtained by short far infrared pulses generated by a free electron laser. The HF coupling into the fundamental mode of the traveling wave transmission line is tested using the bulk OR in GaAs. Whereas the observed signal clearly demonstrates the principle of our...
Depressed contractility of failing myocytes involves a decreased rate of rise of the Ca transient. Synchronization of Ca release from the junctional sarcoplasmic reticulum (SR) is responsible for the rapid rise of the normal Ca transient. This study examined the idea that spatially and temporally dyssynchronous SR Ca release slows the rise of the cytosolic Ca transient in failing feline myocyte...
Background Heart failure with preserved ejection fraction (HF-PEF) is common and has a poor prognosis with a 3 year mortality rate of 23%. There are currently no effective therapies for this condition. HF-PEF is characterized by symptoms of heart failure, normal or a mildly impaired ejection fraction and evidence of adverse cardiac and vascular remodelling. A feature of all heart failure is a h...
