In recent years, Pulsed Field Ablation (PFA) has emerged as a novel non thermal energy source for ablation. To compare lesion durability and collateral damage between unipolar/biphasic PFA RF delivered through contact-force sensing catheter both in point-by-point fashion. A 4 arm pre-clinical study (n=12 swine) was designed with the multimodality generator TRUPULSE™ 2. nominal dose (12 pulses) ...

We report first–principles frozen–phonon calculations for the determination of the force–free geometry and the dynamical matrix of the five Raman–active A1g modes in YBa2Cu3O7. To establish the shape of the phonon potentials atomic forces are calculated within the LAPWmethod. Two different schemes – the local density approximation (LDA) and a generalized gradient approximation (GGA) – are emplo...

we have investigated the electronic structure and thermodynamic properties of supercell of the
-al2o3 by first-principles calculation in framework of density functional theory (dft) and full potential linearized augmented plane wave (fp-lapw) with generalized gradient approximation (gga) and by quasi-harmonic debye model. our calculated value for direct band gap of α-al2o3 is 7.2 ev which is v...

The prevention of esophageal thermal injury (ETI) during atrial fibrillation (AF) ablation is still a challenge and the optimal luminal temperature (LET) strategy remains to be proved. Recent studies showed lower incidence (3.5- 6%) endoscopic ETI high-power, short-duration (HPSD) AF in which radiofrequency (RF) delivery was tolerated at LET cutoff point 39-41°C. We investigated whether monitor...

In this research paper, we investigated the structural, electronic, and magnetic features of titanium atom substituting calciumatom in rock salt structure CaS to explore new dilute semiconductor compounds. The calculations are carried out using full potential linearized augmented plane wave (FP-LAPW) method based on spin-polarized density functional theory, implemented WIEN2k code. generalized ...

In this theoretical study, we presents for the first time, to best of our knowledge, structural, electronic and elastic properties perovskite Sr0.5Be0.5TiO3 type structure (Tetragonal), P4/mmm, space group, 123.using full potential linearized augmented plane wave (FP-LAPW) method on basis density functional theory (DFT) integrated in Wien2k code .
