Computer Simulations of Mulljple-Quantum NMR Experiments. II. Selective Excitation

The effects of selective multiplequantum pulse sequences have previously been analyzed by coherent averaging theory. However, convergence of the Magnus expansion used for those calculations is questionable in the experimentally important region of long cycle times. Exact density matrix evolutions arc calculated here to show when the coherent averaging calculations will be reliable. In addition,...

Computer Simulations of Multiple-Quantum NMR Experiments. I. Nonselective Excitation

The multiplequantum (MQ) evolution of anisotropic spin systems with four to eight coupled protons is analyzed using a computer for the basic three-pulse sequence. MQ intensities are first investigated as a function of preparation time. The concept of timeindependent intensities is then introduced, and an algorithm for efficient computation of these quantities is described. A correlation between...

A Quantum-Inspired Ensemble Method and Quantum-Inspired Forest Regressors

We propose a Quantum-Inspired Subspace(QIS) Ensemble Method for generating feature ensembles based on feature selections. We assign each principal component a Fraction Transition Probability as its probability weight based on Principal Component Analysis and quantum interpretations. In order to generate the feature subset for each base regressor, we select a feature subset from principal compon...
