Entrainment of cortical rhythms to acoustic rhythms has been hypothesized to be the neural correlate of pulse and meter perception in music. Dynamic attending theory first proposed synchronization of endogenous perceptual rhythms nearly 40 years ago, but only recently has the pivotal role of neural synchrony been demonstrated. Significant progress has since(More)
BACKGROUND Mild cognitive impairment (MCI) is a transitional state between normal aging and dementia. Identifying this condition would allow early interventions that may reduce the rate of progression to Alzheimer's disease (AD). We examined the efficacy of a six-month cognitive intervention program (CIP) in patients with MCI and to assess patients'(More)
One of the main drawbacks of the Smith predictor (SP) for controlling systems affected by external delays is that the resulting performance relies on the accuracy of the knowledge regarding such delays. Thus, as the mismatch between the true value of the delay and the nominal one employed for control purposes increases the closed loop performance(More)
This paper designs a discrete-time state-feedback output tracking control for the heart rate during treadmill exercise. Initially, the nonlinear model describing the relationship between the heart rate and the speed of a treadmill is discretized. Afterwards, a feedback linearization-based control law is proposed to achieve perfect output tracking. The(More)
In the framework of complete probabilistic Menger metric spaces, this paper investigates some relevant properties of convergence of sequences built through sequences of operators which are either uniformly convergent to a strict k-contractive operator, for some real constant k ∈ (0, 1), or which are strictly k-contractive and point-wisely convergent to a(More)
In this paper, we develop a multimodel adaptive control strategy to be applied to delay compensation schemes for unstable systems. The strategy is based on intelligent control and the only requirement about the system is that the delay is unknown but bounded. The proposed approach can be used on any delay compensation scheme increasing the robustness of the(More)
In the present article we propose to model the dynamics of neurotransmitters by means of random walkers, it is possible to affirm that there is a relation of the distance between neurons and the amount of neurotransmitters that reach the receptors of the post-synaptic neuron, with The purpose of being able to understand roughly how neural connections work(More)
