— The feedback capacity of the stationary Gaussian additive noise channel has been open, except for the case where the noise is white. Here we obtain the closed-form feedback capacity of the first-order moving average additive Gaussian noise channel. Specifically, the channel is given by Yi = Xi + Zi, i = 1, 2,. .. , where the input {Xi} satisfies average(More)
Enhancing the working memory of stroke patients using tDCS. Objectives: We investigated whether anodal transcranial direct current stimulation over the left dorsolateral prefrontal cortex affected the working memory performance of patients after a stroke. Design: Ten patients (mean age 47.7 yrs) with cognitive deficits after a first-ever stroke participated(More)
