The heteronuclear cross-polarization efficiency in the rotating frame can be improved by sweeping the radiofrequency amplitude adiabatically through the Hartmann-Hahn condition. The enhancement is particularly significant for strongly coupled IS spin syste ...
New NMR techniques are described for transferring transverse magnetization between scalar-coupled nuclei in the rotating frame. The methods involve simultaneous spin-locking of two selected spins A and X, using cosinusoidal modulation of the radio frequenc ...
The author offers a solution which uses a separate representation entity, called the connection frame, to model the spatial relationships between a pair of objects and how those relationships achieve force or velocity propagation. The connection representa ...
A general frame is proposed for implementing 8-bit coded character sets in Ada in conformance with current international standards. This frame is then applied to what is termed Latin alphabet No. 1 which covers Western European languages. Also shown is how ...
Two methods, based on the phase modulation of spin-echo signals due to J-coupling, of selective simplification of coupled homonuclear spectra are described. Both pulse methods employ a 90 Deg-t-180 Deg-t spin-echo sequence to prep. suitable phases of the m ...
The coordination and cooperation strategies of Micro Aerial Vehicles (MAVs) become increasingly popular to carry out high-level, complex tasks such as object transporta- tion, patrolling, inspection robustly and with high performance. One of the crucial co ...
In crowded NMR spectra, it is shown how longitudinal relaxation rates (lab.-frame rates 1/T1) can be measured by selective inversion-recovery of a chosen site A followed by selective transfer of magnetization to another site X through a scalar coupling JAX ...
The existence and dynamics of vortical structure in both homogeneous and inhomogeneous systems will be discussed. In particular the dynamics of monopolar and dipolar vortices in a plasma with nonuniform density and in a rotating fluid with varying Coriolis ...
