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

open access: yesNeuroImage, 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

open access: yesIEEE 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 unified closed-loop stability measure for finite-precision digital controller realizations implemented in different representation schemes [PDF]

open access: yes, 2003
The closed-loop stability issue of finite-precision realizations is investigated for digital controllers implemented in three different arithmetic formats, namely fixed-point, floating-point and block-floating-point schemes.

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

open access: yesThe 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-

On Validating Closed-Loop Behaviour from Noisy Frequency-Response Measurements [PDF]

open access: yes, 2005
It is shown how noisy closed-loop frequency-response measurements can be used to obtain pointwise in frequency bounds on the possible difference between the actual closed-loop system and the closed-loop comprising a nominal model of the plant and the ...

Closed-Loop Neuromorphic Benchmarks

open access: yesFrontiers in Neuroscience, 2015
Evaluating the effectiveness and performance of neuromorphic hardware is difficult. It is evenmore difficult when the task of interest is a closed-loop task; that is, a task where the outputfrom the neuromorphic hardware affects some environment, which ...

Manufacturer-remanufacturing vs supplier-remanufacturing in a closed-loop supply chain [PDF]

open access: yes, 2016
Remanufacturing at the component level could be performed by either a manufacturer or a supplier. In this paper, we analyze the performance of manufacturer-remanufacturing and supplier-remanufacturing in a decentralized closed-loop supply chain, and ...
