There was also no significant difference between patients and spouses in the subcategories of QoL with the exception of the perceived effect on work life, which was greater in patients than spouses
(P = 0.041).
Conclusions: AF has a similar perceived impact on the QoL of spouses and patients. QoL improvement strategies for patients with AF should take spouses into account. (PACE 2011; 34: 804-809)”
“Information processing in the human brain arises from both interactions between adjacent areas and from Citarinostat concentration distant projections that form distributed brain systems. Here we map interactions across different spatial scales by estimating the degree of intrinsic functional connectivity for the local (<= 14 mm) neighborhood directly surrounding brain regions as contrasted with distant (>14 Prexasertib ic50 mm) interactions. The balance between local and distant functional interactions measured at rest forms a map that separates sensorimotor cortices from heteromodal association areas and further identifies regions that possess both high local and distant cortical-cortical interactions. Map estimates of network measures demonstrate that high local connectivity is most often associated with a high clustering
coefficient, long path length, and low physical cost. Task performance changed the balance between local and distant functional coupling in a subset of regions, particularly, increasing local functional coupling in regions engaged by the task. The observed
properties suggest that the brain has evolved a balance Tariquidar datasheet that optimizes information-processing efficiency across different classes of specialized areas as well as mechanisms to modulate coupling in support of dynamically changing processing demands. We discuss the implications of these observations and applications of the present method for exploring normal and atypical brain function.”
“A modified Landau-Ginzburg-Devonshire theory is developed to investigate the “”diameter-temperature”" phase diagram and the ferroelectric behaviors of BaTiO3 nanowires. Four phases, such as the Cubic phase, the Tetragonallike phase, the Orthorhombic phase, and the Monoclinic phase, are obtained. The ferroelectric phase transition temperatures are all depressed as the diameter decreases. A temperature-dependent critical diameter below which the polarization disappears is 0.8 nm at 0 K. Moreover, the magnitude and the direction of the polarization are strongly dependent on the diameter as well as the dielectric behaviors. Therefore, it can generate a specific direction of the polarization by controlling the diameter of the nanowires which may optimize the physical properties. (C) 2011 American Institute of Physics.
