Charge Segregation, Cluster Spin-Glass and Superconductivity in La1.94Sr0.06CuO4

, 1999
A 63Cu and 139La NMR/NQR study of superconducting (Tc=7 K) La1.94Sr0.06CuO4 single crystal is reported. Coexistence of spin-glass and superconducting phases is found below ~5 K from 139La NMR relaxation. 63Cu and 139La NMR spectra show that, upon cooling,

Towards Optimizing Neural Network-Based Quantification for NMR Metabolomics

Metabolites
Background: Quantification of metabolites from nuclear magnetic resonance (NMR) spectra in an accurate, high-throughput manner requires effective data processing tools. Neural networks are relatively underexplored in quantitative NMR metabolomics despite
