The cuff-leak test was widely used for the prediction of post-extubation stridor, but controversial results limit its clinical application. The current study used real-time ultrasonography to evaluate the air-leak and hypothesised that the air-column width, measured by ultrasonography, may be correlated to the development of post-extubation stridor. From June 1, 2001 to March 1, 2002, a total o...

Variational quantum eigensolver (VQE) is an appealing candidate for the application of near-term computers. A technique introduced in [Higgot et al., Quantum 3, 156 (2019)], which named variational deflation (VQD), has extended ability VQE framework finding excited states a Hamiltonian. However, no method to evaluate transition amplitudes between eigenstates found by VQD without using any costl...

Background: With respect to physical relations in force and pressure, we hypothesized that the prevalence of traumatic tympanic membrane perforation in patients with a patulous Eustachian tube is greater than normal, because in Eustachian tube patency, the internal air pressure of the middle ear will not increase after compression, subsequent to trauma. Therefore the force upon the tympanic...

Recent improvements to the QZ algorithm for solving generalized eigenvalue problems are summarized. Among the major modifications are novel multishift QZ iterations based on chasing chains of tiny bulges and an extension of the so called aggressive early deflation strategy. The former modification aims to improve the execution time of the QZ algorithm on modern computing systems without changin...

A new method for dimensionality reduction and feature extraction based on Support Vector Machines and minimization of the within-class data dispersion is proposed. An iterative procedure is proposed that successively applies Support Vector Machines on perpendicular subspaces using the deflation transformation in such a way that the within-class variance is minimized. The proposed approach is pr...

We studied 99 patients who were undergoing total knee arthroplasty (TKA) to determine the optimum protocol for the administration of tranexamic acid (TNA) in order to reduce blood loss. It decreased by more than 40% after the administration of TNA. The haemostatic effect was greatest when TNA was given preoperatively and on deflation of the tourniquet. There was no increase in the incidence of ...
