Reduction in the Resonance Error in Numerical Homogenization II: Correctors and Extrapolation [PDF]

Foundations of Computational Mathematics, 2015
This paper is the companion article of [Gloria, M3AS, 21 (2011), No. 3, pp 1601-1630]. One common drawback among numerical homogenization methods is the presence of the so-called resonance error, which roughly speaking is a function of the ratio $\frac{\varepsilon}ρ$, where $ρ$ is a typical macroscopic lengthscale and $\varepsilon$ is the typical size ...

ERROR ANALYSIS AND PROPAGATION IN METABOLOMICS DATA ANALYSIS

Computational and Structural Biotechnology Journal, 2013
Error analysis plays a fundamental role in describing the uncertainty in experimental results. It has several fundamental uses in metabolomics including experimental design, quality control of experiments, the selection of appropriate statistical methods,

Reducing Unitary and Spectator Errors in Cross Resonance with Optimized Rotary Echoes

PRX Quantum, 2020
We present an improvement to the cross resonance gate realized with the addition of resonant, target rotary pulses. These pulses, applied directly to the target qubit, are simultaneous to and in phase with the echoed cross resonance pulses.

Quantization error in magnetic resonance imaging

Concepts in Magnetic Resonance Part A, 2014
ABSTRACTDue to the special nature of the acquisition domain, the quantization process of magnetic resonance imaging (MRI) data presents challenges that are not present in other medical imaging techniques. In this article, we demonstrate that the quantization error in MRI cannot be assumed to be a random variable with uniform distribution across the ...
