Comparative Study of Wavelet Based Unsupervised Ocular Artifact Removal Techniques for Single Channel EEG Data
Electroencephalogram (EEG) is a technique for recording asynchronous activation of neuronal firing inside the brain with non-invasive scalp electrodes. Artifacts such as eye blink activities can corrupt these neuronal signals. While ocular artifact (OA) removal is well investigated for multiple channel EEG systems, in alignment with the recent momentum towards minimalistic EEG systems for use in natural environments, we investigate unsupervised and effective removal of OA from single-channel streaming raw EEG data.
Electric Stimulus-Responsive Chitosan/MNP composite Microbeads for a Drug Delivery System
In this work, we explored a novel technique of using electric pulses as stimulus to regulate vancomycin elution profile release from a chitosan-based drug delivery substrate. Inkjet printing technology was used to print silver electrodes on an inexpensive, flexible, thin polyimide substrate. We demonstrated a significantly higher release of vancomycin from the groups that received excitation, compared to groups that did not. Such controllable drug release systems that are responsive to external stimuli will assist healthcare providers in customizing drug administration as dictated by the specific needs of each patient, thus improving overall drug efficacy.
