Design Intelligent Pressure Sensing Devices and System Integrated with Conductor‐Coated Porous Composites

Advanced Sensor Research, Volume 2, Issue 5, May 2023., 2023
Porous composite sensors have the advantage of a wide deformation range owing to their structural characteristics. Conductor‐coated porous composites (CCPCs), consisting of a conductive coating and an insulating elastomeric skeleton, exhibit high compressibility and a facile fabrication process.

Ontogenetic effects of brood parasitism by the Brown‐headed Cowbird on host offspring

Ecology, Volume 104, Issue 3, March 2023., 2023
Abstract Nest‐sharer avian brood parasites do not evict or otherwise kill host chicks, but instead inflict a range of negative effects on their nestmates that are mediated by interactions between the parasite and host life history traits. Although many of the negative fitness effects of avian brood parasitism are well documented across diverse host ...

[Retracted] Edge‐Enabled Heart Rate Estimation from Multisensor PPG Signals

Journal of Healthcare Engineering, Volume 2023, Issue 1, 2023., 2023
Heart rate (HR) estimation from multisensor PPG signals suffers from the dilemma of inconsistent computation results, due to the prevalence of bio‐artifacts (BAs). Furthermore, advancements in edge computing have shown promising results from capturing and processing diversified types of sensing signals using the devices of Internet of Medical Things ...

Changes in white matter functional networks during wakefulness and sleep

Human Brain Mapping, Volume 43, Issue 14, Page 4383-4396, October 1, 2022., 2022
Using simultaneous EEG‐fMRI data during wakefulness and NREM sleep collected from 66 healthy participants, we constructed 10 stable white matter functional networks using clustering analysis. These observations provide direct physiological evidence that neural activities in the white matter are modulated by the sleep–wake cycle.

Extracting electrophysiological correlates of functional magnetic resonance imaging data using the canonical polyadic decomposition

Human Brain Mapping, Volume 43, Issue 13, Page 4045-4073, September 2022., 2022
We show that EEG features of BOLD‐fMRI dynamics can be obtained using the canonical polyadic decomposition. Hemodynamic response functions are also estimated in the process, which allows one to model BOLD‐fMRI signals using EEG signals. We employ our method on simulated data, as well as publicly available task‐based and resting‐state EEG‐fMRI data ...

Systematic evaluation of recursive approach of EEG‐segment‐based PCA for removal of helium‐pump artefact from MRI

Electronics Letters, Volume 58, Issue 15, Page 567-569, July 2022., 2022
Abstract The cryogenic pump is a crucial component of the magnetic resonance imaging (MRI) system for delivering liquid helium to a magnet for superconductivity, thereby generating a mechanical vibration. Thus, the cryogenic pump for liquid helium (helium pump) contaminates the electroencephalography (EEG) simultaneously acquired with functional MRI ...

Unobtrusive Estimation of Cardiovascular Parameters with Limb Ballistocardiography

Sensors, 2019
This study investigates the potential of the limb ballistocardiogram (BCG) for unobtrusive estimation of cardiovascular (CV) parameters. In conjunction with the reference CV parameters (including diastolic, pulse, and systolic pressures, stroke volume ...
