This paper presents a patch-based non-parametric approach to the correction of intensity inhomogeneity from magnetic resonance (MR) images of the human brain. During image acquisition, the inhomogeneity present in the radio-frequency coil, is usually manifested on the reconstructed MR image as a smooth shading effect. This artifact can significantly deteriorate the performance of any kind of im...

Gravitational physics of VLBI experiment conducted on September 8, 2002 and dedicated to measure the speed of gravity (a fundamental constant in the Einstein equations) is treated in the first post-Newtonian approximation. Explicit speedof-gravity parameterization is introduced to the Einstein equations to single out the retardation effect caused by the finite speed of gravity in the relativist...

Gravitational physics of VLBI experiment conducted on September 8, 2002 and dedicated to measure the speed of gravity is treated in the first post-Newtonian approximation. Explicit speed-of-gravity parameterization is introduced to the Einstein equations to single out the retardation effect caused by the finite speed of propagation of gravity in the relativistic time delay of light, passing thr...

We derive a system of three coupled equations that implicitly defines a continuous one-parameter family of expanding wave solutions of the Einstein equations, such that the Friedmann universe associated with the pure radiation phase of the Standard Model of Cosmology is embedded as a single point in this family. By approximating solutions near the center to leading order in the Hubble length, t...

Named entity recognition has achieved remarkable success on benchmarks with high-quality manual annotations. Such annotations are labor-intensive and time-consuming, thus unavailable in real-world scenarios. An emerging interest is to generate low-cost but noisy labels via distant supervision, hence label learning algorithms demand. In this paper, a unified self-adaptive framework termed Self-A...

This paper proposes a new convergence acceleration method specialized for the magnetic field analyses of synchronous machines based on time-periodic explicit-error-correction (TP-EEC) method. The proposed constructs an auxiliary equation error correction in dq rotational reference frame to convert fundamental harmonic component into DC component. conversion enables us perform using TP-EEC at in...

This article describes a generic bundle adjustment methodology for multi-view stereo pipelines 3D reconstruction from high-resolution optical satellite imagery. The Rational Polynomial Camera (RPC) model of each input view is refined by composing it with rotation that compensates errors related to the attitude angles encoding orientation. A set tie points, derived feature tracks detected across...

Abstract This aptitude–treatment interaction study investigated the extent to which explicit and implicit cognitive abilities are differentially related learning outcomes under two corrective feedback conditions. One hundred thirteen intermediate English learners of Spanish were randomly assigned an (recast), (explicit correction), or control group after completing tests from aptitude batteries...
