Background The objective of this study was to evaluate the existence of cognitive plateaus in some individuals during the course of Alzheimer's disease (AD). Methods Data came from the historical patient group collected via the Consortium to Establis

The response matrix A is defined by the equation X = AΘ, where Θ is the kick vector and X is the resulting orbit vector. Since A is not necessarily a symmetric or even a square matrix we symmetrize it by using ATA. Then we find the eigenvalues and

We describe the creation and trapping of ions by an electron beam and the coherent and incoherent instabilities that the trapped ions can cause. The transverse oscillations and longitudinal motion of the ions and the different methods of beam shaking

The electron beam in a storage ring collides with the residual gas in the vacuum chamber. As a consequence, low velocity positive ions are produced and trapped in the potential well of the electron beam. They perform stable or unstable oscillations a

At the NSLS storage rings capacitive pickups (PUEs) with four circular electrodes are used as beam position monitors. The dependence of the induced signal on the actual beam position for the geometry of the vacuum chamber and electrodes is studied bo

A global closed-orbit feedback experiment based upon a real-time harmonic analysis of both the orbit movement and the correction magnetic fields is described. The harmonic feedback system was constructed and tested on the 750 MeV vacuum ultraviolet r

The pickup electrodes (PUEs) in the NSLS (National Synchrotron Light Source) storage rings are of the four-button type. Near the center of the PUE, the beam position can be well approximated with a linear function of the sum and the difference signal

We are reporting on the design and preliminary results of a prototype digital feedback system for the storage rings at the NSLS. The system will use a nonlinear eigenvector decomposition algorithm. It will have a wide dynamic range and will be able t
