background and aim: some risk factors for obstructive sleep apnea (osa) such as upper respiratory airways abnormalities and obesity overlap with the risk factors for eustachian tube dysfunction (etd). in this study, we investigated the prevalence of etd in a population of patients with osa. methods: tubal dysfunction was determined by tympanometry and inflation-deflation test in 36 patients dia...

D eflation, the opposite of inflation, is a situation of falling general prices. It should not be confused with disinflation, which refers to a declining inflation rate that nevertheless remains positive. It was the successful U.S. disinflation of the 1990s, a disinflation that lowered the inflation rate sufficiently to create concern that further downward pressure might push it into negative t...

BACKGROUND Inflation and deflation of a pneumatic tourniquet used in total knee replacement surgery induces various changes in patient's hemodynamic and metabolic status, which may result in serious complications, especially in aged patients. Near-infrared spectroscopy (NIRS) is a monitoring device designed to estimate the regional cerebral oxygen saturation. We evaluated the effect of tourniqu...

Aggressive early deflation has proven to significantly enhance the convergence of the QR algorithm for computing the eigenvalues of a nonsymmetric matrix. One purpose of this paper is to point out that this deflation strategy is equivalent to extracting converged Ritz vectors from certain Krylov subspaces. As a special case, the single-shift QR algorithm enhanced with aggressive early deflation...

Close to the chiral limit, many calculations in numerical lattice QCD can potentially be accelerated using low-mode deflation techniques. In this paper it is shown that the recently introduced domain-decomposed deflation subspaces can be propagated along the field trajectories generated by the Hybrid Monte Carlo (HMC) algorithm with a modest effort. The quark forces that drive the simulation ma...

CANDECOMP/PARAFAC (CPD) approximates multiway data by sum of rank-1 tensors. Our recent study has presented a method to rank-1 tensor deflation, i.e. sequential extraction of the rank-1 components. In this paper, we extend the method to block deflation problem. When at least two factor matrices have full column rank, one can extract two rank-1 tensors simultaneously, and rank of the data tensor...

background: to assess the endothelial function via noninvasive method, in pregnant women with preeclampsia compared to normotensive pregnant women. materials and methods: brachial artery diameter was measured via ultrasound, in 28 women with preeclampcia in case group and normotensive pregnant women in control group, at rest, after inflation of sphygmomanometer cuff up to 250-300 mmhg, immediat...
