Background During automated radiofrequency (RF) annotation-guided pulmonary vein isolation (PVI), respiratory motion adjustment (RMA) is recommended, yet lacks in vivo validation. Methods Following contact force (CF) PVI (continuous RF, 30 W) using general anesthesia and RF annotation-guidance (VISITAG™: force-over-time 100% minimum 1 g; 2 mm position stability; ACCURESP™ RMA “off”) 25 patients...

background: old methods of administrating can't cover the rapid changes of today. these changes redounded new organizations like learning organizations to be formed. the purpose of this research is to study the relationship between the learning organization and organizational commitment among nursing managers. methods: this is a descriptive analytic survey. the population of study was 90 nursin...

A theoretical study of electronic and optical properties of PbTe using the full-potential augmented plane waves (FP-LAPW) within density-functional theory (DFT) was presented as implemented in WIEN2k code. We adopted the dipole approximation in our optical calculations. The dielectric function was calculated in the momentum representation, which requires matrix elements of the momentum p betwee...

Using the density-functional theory within the Full Potential Linear Augmented PlaneWave (FP-LAPW) method, we have calculated, in this work, the equation of state, the e ective charges and the phonon dispersion along [100] and [111] directions for the cubic III-Nitrides(c-BN, c-AlN, c-GaN and c-InN), including hydrostatic strains dependence. A good agreement with the micro-Raman scattering expe...

The electronic structure of SrBi 2 Ta 2 O 9 is investigated from first-principles, within the local density approximation, using the full-potential linearized augmented plane wave (LAPW) method. The results show that, besides the large Ta(5d)-O(2p) hybridization which is a common feature of the ferroelectric perovskites, there is an important hybridization between bismuth and oxygen states. The...

Dennis Lo, also called Yuk Ming Dennis Lo, is a professor at the Chinese University of Hong Kong [5] in Hong Kong, China. In 1997, Lo discovered fetal DNA in maternal plasma, which is the liquid component of a pregnant woman's blood. By 2002, Lo distinguished the DNA differences between pregnant women and their fetuses, enabling scientists to identify fetal DNA in pregnant women's blood. Lo use...
