BACKGROUND: Previous studies based on local case series estimated the annual incidence of endocarditis in the U.S.at about 4 per 100,000 population.Small-scale studies elsewhere have reported similar incidence rates.However, no nationally-representative population-based studies have verified these estimates.METHODS AND FINDINGS: Using the 1998-2009
Natural Deep Eutectic Solvents as Rust Removal Agents from Lithic and Cellulosic Substrates
The peculiar physicochemical features of deep eutectic solvents (DESs), in particular their tunability, make them ideal media for various applications.Despite their ability to solubilize metal oxides, their use as rust removers from valuable substrates has not yet been thoroughly investigated.In this Call Bells study, we chose three known DESs, con
A Multi-Global Navigation Satellite System (GNSS) Time Transfer Method with Federated Kalman Filter (FKF)
Relative to single Global Navigation Satellite System (GNSS) measurements, i.e., the measurements from a single GNSS system, a single GNSS code, and a single GNSS receiver, multi-GNSS measurements for time transfer could improve reliability and provide better short-term stability.Previous studies applied equal weighting to different GNSS systems or
Cylinder quantum field theories at small coupling
Abstract We show that any 2D scalar field theory compactified on a cylinder and with a Fourier expandable potential V is equivalent, in the small coupling limit, to a 1D theory involving a massless particle in a potential V and an infinite tower of free massive Kaluza-Klein (KK) modes.Moving slightly away from the deep IR region has the effect of s
