Geometric property of off resonance error robust composite pulse [PDF]
Scientific Reports, 2022 The precision of quantum operations is affected by unavoidable systematic errors. A composite pulse (CP), which has been well investigated in nuclear magnetic resonance (NMR), is a technique that suppresses the influence of systematic errors by replacing

Measurement of T1 Mapping in Patients With Cardiac Devices: Off-Resonance Error Extends Beyond Visual Artifact but Can Be Quantified and Corrected [PDF]
Frontiers in Cardiovascular Medicine, 2021 Background: Measurement of myocardial T1 is increasingly incorporated into standard cardiovascular magnetic resonance (CMR) protocols, however accuracy may be reduced in patients with metallic cardiovascular implants.

Reducing Probability of Decision Error Using Stochastic Resonance [PDF]
IEEE Signal Processing Letters, 2006 The problem of reducing the probability of decision error of an existing binary receiver that is suboptimal using the ideas of stochastic resonance is solved. The optimal probability density function of the random variable that should be added to the input is found to be a Dirac delta function, and hence, the optimal random variable is a constant.

Prediction and reduction of dynamic factor based on dynamic behavior of gear systems [PDF]
Scientific ReportsGears operating at high rotational speeds are prone to resonance-induced load amplification, which can significantly shorten their service life. This study quantifies the dynamic factor ( $$\:{K}_{v}$$ ) of a spur gear pair operating between 500 and 4 ...

An Elliptic Local Problem with Exponential Decay of the Resonance Error for Numerical Homogenization
Multiscale Modeling and Simulation, 2023 Numerical multiscale methods usually rely on some coupling between a macroscopic and a microscopic model. The macroscopic model is incomplete as effective quantities, such as the homogenized material coefficients or fluxes, are missing in the model. These effective data need to be computed by running local microscale simulations followed by a local ...

On the Nature of the Boundary Resonance Error in Numerical Homogenization and Its Reduction
Multiscale Modeling and SimulationNumerical homogenization of multiscale equations typically requires taking an average of the solution to a microscale problem. Both the boundary conditions and domain size of the microscale problem play an important role in the accuracy of the homogenization procedure.

Mitigating off-resonant error in the cross-resonance gate [PDF]
Physical Review A, 2022 Off-resonant error for a driven quantum system refers to interactions due to the input drives having non-zero spectral overlap with unwanted system transitions. For the cross-resonance gate, this includes leakage as well as off-diagonal computational interactions that lead to bit-flip error on the control qubit.

Mismeasurement and the Resonance of Strong Confounders: Correlated Errors [PDF]
American Journal of Epidemiology, 1999 Confounding in epidemiology, and the limits of standard methods of control for an imperfectly measured confounder, have been understood for some time. However, most treatments of this problem are based on the assumption that errors of measurement in confounding and confounded variables are independent.
