A Unified and Generalized Approach to Quantum Error Correction

, 2004
We present a unified approach to quantum error correction, called operator quantum error correction. This scheme relies on a generalized notion of noiseless subsystems that is not restricted to the commutant of the interaction algebra.

Robust Standard Error Estimators for Panel Models: A Unifying Approach

Journal of Statistical Software, 2017
The different robust estimators for the standard errors of panel models used in applied econometric practice can all be written and computed as combinations of the same simple building blocks.

Standard error and confidence interval for QALY weights [PDF]

There are some problems with the standard errors of QALY weights proposed by Groot (2000, Journal of Health Economics 19). The standard errors show smaller values than those of Groot when we recalculate using his method.

Standard Error Estimation in Invariance Alignment

Mathematics
The invariance alignment (IA) method enables group comparisons in factor models involving either continuous or discrete items. This article evaluates the performance of the commonly used delta method for standard error estimation against alternative ...

Responses’ Prediction Standard Error Analysis in Pareto Solutions

MATEC Web of Conferences, 2017
A Pareto front provides to the decision-maker a set of optimal solutions from where a unique solution should be selected to solve a multiresponse problem.

Estimation of subgraph density in noisy networks

, 2020
While it is common practice in applied network analysis to report various standard network summary statistics, these numbers are rarely accompanied by uncertainty quantification.

A Portrayal of Sliding Mode Control Through Adaptive Neuro Fuzzy Inference System With Optimization Perspective

IEEE Access
Sliding mode control is a promising approach for designing controllers for systems with empirical characteristics. This is a favored nonlinear control strategy that effectively addresses the uncertainties present in derived mathematical models.

Notes on a 3-term Conjugacy Recurrence for the Iterative Solution of Symmetric Linear Systems [PDF]

We consider a 3-term recurrence, namely CG_2step, for the iterative solution of symmetric linear systems. The new algorithm generates conjugate directions and extends some standard theoretical properties of the Conjugate Gradient (CG) method [10].

S-Parameter Uncertainties in Network Analyzer Measurements with Application to Antenna Patterns [PDF]

, 2007
An analytical method was developed, to estimate uncertainties in full two-port Vector Network Analyzer measurements, using total differentials of S-parameters.

Why Queerness is not enough [PDF]

, 2014
Moral error theorists often claim to be strongly anti‑metaphysical in their moral scepticism and atheistic naturalists. This paper argues that pre‑ cisely this becomes a problem for them, when their metaethical and ontologi‑
