COVARIANT OPERATOR BASES FOR CONTINUOUS VARIABLES

Covariant operator bases for continuous variables

Coherent-state representations are a standard tool to deal with continuous-variable systems, as they allow one to efficiently visualize quantum states in phase space.Here, we work out an alternative basis consisting of monomials on C the basic observables, with the crucial property of behaving well under symplectic transformations.This basis is the

Prevalence of and risk factors for perioperative arrhythmias in neonates and children after cardiopulmonary bypass: continuous holter monitoring before and for three days after surgery

Abstract Background A comprehensive evaluation of postoperative arrhythmias following surgery for congenital heart disease by continuous Holter monitoring has not been carried out.We aimed, firstly, to establish the time course of pre- and early postoperative arrhythmias by beat-to-beat analysis following cardiopulmonary bypass and, secondly, to ex

Synergistic effects of bacteriophage cocktail and antibiotics combinations against extensively drug-resistant Acinetobacter baumannii

Abstract Background The extensively drug-resistant (XDR) strains of Acinetobacter baumannii have become a major cause of nosocomial infections, increasing morbidity and mortality worldwide.Many different treatments, including phage therapy, are attractive ways to overcome the challenges of antibiotic resistance.Methods This study investigates the b
