A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Coherent control using adaptive learning algorithms

open access: yes, 2001
We have constructed an automated learning apparatus to control quantum systems. By directing intense shaped ultrafast laser pulses into a variety of samples and using a measurement of the system as a feedback signal, we are able to reshape the laser ...

Signal adaptive control architecture for ΔΣmodulator design

open access: yesElectronics Letters, 1999
A signal adaptive control architecture for a second-order /spl Delta//spl Sigma/ modulator design is presented. This architecture effectively reduces the power dissipation and the distortion of the first stage in the modulator. The function of this architecture is to switch off the DAC feedback signal to the first stage during some iterations, and to ...
