Toward smarter BCIs: extending BCIs through hybridization and intelligent control [PDF]

Journal of Neural Engineering, 2011
This paper summarizes two novel ways to extend brain-computer interface (BCI) systems. One way involves hybrid BCIs. A hybrid BCI is a system that combines a BCI with another device to help people send information. Different types of hybrid BCIs are discussed, along with challenges and issues.

A Wearable Brain–Computer Interface for Mitigating Car Sickness via Attention Shifting

Advanced Science, EarlyView.
Car sickness poses a major challenge in vehicular travel, yet effective nonpharmacological solutions are scarce. We developed a wearable, closed‐loop mindfulness BCI that uses real‐time EEG‐based neurofeedback to shift attention away from motion‐induced discomfort. Validated in real‐car experiments involving >100$>100$ susceptible individuals, over 83%

Numerical optimization of metal felt regenerators with axially varying matrix structures for Stirling engines

International Journal of Thermofluids
The regenerator is the crucial component for the performance of any regenerative gas cycle. Due to the changing gas properties and flow conditions in the axial direction of a regenerator, a variation of its parameters in that direction is a promising ...

A Glucose‐Responsive Intelligent Antibacterial and Oxygen‐Producing Hydrogel Promotes the Healing of Diabetic Wounds by Regulating Cellular Heterogeneity

Advanced Science, EarlyView.
We have developed a glucose‐triggered on‐demand drug delivery CF‐CPGaMPN hydrogel based on borate ester bonds. It inactivates microbes, releases oxygen, and enables on‐demand drug release in high‐glucose environments to promote healing of diabetic wounds. Single‐cell sequencing reveals that the CF‐CPGaMPN hydrogel significantly alleviates dysfunctional

Smart Optogenetics for Real‐Time Automated Control of Cardiac Electrical Activity

Advanced Science, EarlyView.
We are able to stop dangerous heart‐rhythm spirals before they fully form. Within about 100 ms, it pinpoints the spiral's tiny central tip (≈0.9 mm) using light‐based sensing and machine learning, then shines targeted light to shut it down. This fast, precise, closed‐loop approach detects, targets, and terminates arrhythmias in real time.

Robust artifactual independent component classification for BCI practitioners [PDF]

, 2014
Objective. EEG artifacts of non-neural origin can be separated from neural signals by independent component analysis (ICA). It is unclear (1) how robustly recently proposed artifact classifiers transfer to novel users, novel paradigms or changed ...

Bipolar fuzzy BCI-implicative ideals of BCI-algebras

Annals of Communications in Mathematics, 2020
The paper introduces the notions of bipolar fuzzy BCI-implicative ideals and bipolar fuzzy closed BCI-implicative ideals of BCI-algebras. It is proved that any bipolar fuzzy BCI-implicative ideal is a bipolar fuzzy ideal but not the converse. Characterizations of bipolar fuzzy BCI-implicative ideals and bipolar fuzzy closed BCIimplicative ideals are ...

Microendovascular Neural Recording from Cortical and Deep Vessels with High Precision and Minimal Invasiveness

Advanced Intelligent Systems, EarlyView.
Intravascular electroencephalography (ivEEG) using micro‐intravascular electrodes was developed. Cortical‐vein ivEEG showed a higher signal‐to‐noise ratio and finer spatial resolution of somatosensory evoked potentials (SEPs) than superior sagittal sinus ivEEG, and deep‐vein ivEEG captured clear visual evoked potentials.
