We study the pion-mass dependence of two-pion channel in hadronic-vacuum-polarization (HVP) contribution to anomalous magnetic moment muon a?HVP, by using an Omnès representation for pion vector form factor with phase shift derived from inverse-amplitude method (IAM). Our results constrain dominant isospin-1 part isospin-symmetric light-quark contribution, and should thus allow one better contr...

Abrupt motion of camera or objects in a scene result blurry video, and therefore recovering high quality video requires two types enhancements: visual enhancement temporal upsampling. A broad range research attempted to recover clean frames from blurred image sequences temporally upsample by interpolation, yet there are very limited studies handling both problems jointly. In this work, we prese...

High-resolution spectrum estimation techniques have been extensively studied in recent publications. Knowledge of the noise variance is vital for spectrum estimation from noise-corrupted observations. This paper presents the use of noise compensation and data extrapolation for spectrum estimation. We assume that the observed data sequence can be represented by a set of autoregressive parameters...

This paper describes a very efficient algorithm for image signal extrapolation. It can be used for various applications in image and video communication, e. g. the concealment of data corrupted by transmission errors or prediction in video coding. The extrapolation is performed on a limited number of known samples and extends the signal beyond these samples. Therefore the signal from the known ...

Splitting extrapolation is an efficient technique for solving large scale scientific and engineering problems in parallel. This article discusses a finite element splitting extrapolation for second order hyperbolic equations with time-dependent coefficients. This method possesses a higher degree of parallelism, less computational complexity, and more flexibility than Richardson extrapolation wh...

We develop a new 3D wavefield-extrapolation method for a transversely isotropic (TI) medium with a symmetry axis. The wavefield extrapolation is done by an implicit isotropic extrapolation operator with an explicit correction operator. The explicit correction is a 2D convolution operator in the space domain, whose coefficients are estimated by a weighted least-squares method in the Fourier doma...

In two previous papers [lO,ll] convergence and stability results for the following vector extrapolation methods were presented: Minimal Polynomial Extrapolation, Reduced Rank Extrapolation, Modified Minimal Polynomial Extrapolation, and Topological Epsilon Algorithm. The analyses were carried out for vector sequences that include those arising from iterative methods for linear systems of equati...
