"¿Qué es entonces la verdad? Una Hueste en movimiento de metáforas, metonimias, antropomorfismos, en resumidas cuentas, una suma de relaciones humanas que han sido realzadas, extrapoladas y adornadas poética y retóricamente y que, después de un prolongado uso, un pueblo considera firmes, canónicas y vinculantes; las verdades son ilusiones de las que se han olvidado que lo son; metáforas que se ...

We present a study of the results obtained combining LO partonic matrix elements with either LO or NLO partons distributions. These are compared to the best prediction using NLO for both matrix elements and parton distributions. The aim is to determine which parton distributions are most appropriate to use in those cases where only LO matrix elements are available, e.g. as in many Monte Carlo g...

Reductive Claisen rearrangement of 1-allyloxy-8-methoxy-9, 10-anthraquinone followed by demethylation and reduction, and of 1,8-bisallyloxy-9,lO-anthraquinone followed by reduction provides regiospecific syntheses of 2-propyl- and 2,7-dipropyl anthralin

We present an all-electron, periodic ${G}_{\text{0}}{W}_{\text{0}}$ implementation within the numerical atomic orbital (NAO) basis framework. A localized variant of resolution-of-the-identity (RI) approximation is employed to significantly reduce computational cost evaluating and storing two-electron Coulomb repulsion integrals. demonstrate that error arising from RI can be reduced insignifican...

Aim. To study the role of left atrial posterior wall (LAPW) isolation in increasing clinical efficacy radiofrequency ablation (RFA) patients with persistent fibrillation (PeAF) during electrophysiological studies. Methods. A single-center randomized prospective study. From February 2020 to 2021, 35 procedures were performed on PeAF. Patients into two groups - pulmonary vein (PVI) plus LAPW accordi...
