Closed-Loop Identification of Baroreflex Properties in the Frequency Domain

Frontiers in Neuroscience, 2021
The arterial baroreflex system plays a key role in maintaining the homeostasis of arterial pressure (AP). Changes in AP affect autonomic nervous activities through the baroreflex neural arc, whereas changes in the autonomic nervous activities, in turn ...

closed loop

, 2021
Une boucle fermée peut être obtenue par superposition linéaire des deux extrémités libres d'une boucle ouverte. Sa principale propriété est la double dégénérescence de ses états. Les expressions analytiques de ses valeurs propres, de ses fonctions propres et de sa fonction de réponse sont présentées.

Transcranial ultrasound stimulation at the peak-phase of theta-cycles in the hippocampus improve memory performance

NeuroImage, 2023
The present study aimed to investigate the effectiveness of closed-loop transcranial ultrasound stimulation (closed-loop TUS) as a non-invasive, high temporal-spatial resolution method for modulating brain function to enhance memory. For this purpose, we

Learning Lipschitz Feedback Policies From Expert Demonstrations: Closed-Loop Guarantees, Robustness and Generalization

IEEE Open Journal of Control Systems, 2022
In this work, we propose a framework in which we use a Lipschitz-constrained loss minimization scheme to learn feedback control policies with guarantees on closed-loop stability, adversarial robustness, and generalization.

A fully artificial pancreas versus a hybrid artificial pancreas for type 1 diabetes: a single-centre, open-label, randomised controlled, crossover, non-inferiority trial

The Lancet: Digital Health, 2021
Summary: Background: For people with type 1 diabetes, there is currently no automated insulin delivery system that does not require meal input. We aimed to assess the efficacy of a novel faster-acting insulin aspart (Fiasp) plus pramlintide fully closed-

Closed loop identification based on quantization [PDF]

, 2002
This paper proposes a new closed-loop identification scheme for a single-input-single-output control loop. It is based upon a quantizer inserted into the feedback path. The quantizer can be used to generate an equivalent persistently exciting signal with

Cambridge hybrid closed-loop algorithm in children and adolescents with type 1 diabetes: a multicentre 6-month randomised controlled trial

The Lancet: Digital Health, 2022
Summary: Background: Closed-loop insulin delivery systems have the potential to address suboptimal glucose control in children and adolescents with type 1 diabetes. We compared safety and efficacy of the Cambridge hybrid closed-loop algorithm with usual
