Motion-compensated noncontact imaging photoplethysmography to monitor cardiorespiratory status during exercise.
TLDR
We introduce a new method to overcome motion-induced signal corruption in imaging photoplethysmography (iPPG), a remote, contactless diagnostic technique that can assess peripheral blood perfusion. Expand

Relations between BOLD fMRI-Derived Resting Brain Activity and Cerebral Blood Flow
Consistent resting brain activity patterns have been repeatedly demonstrated using measures derived from resting BOLD fMRI data. While those metrics are presumed to reflect underlying spontaneousExpand

Identification of -barrel membrane proteins based on amino acid composition properties and predicted secondary structure
TLDR
This paper performs an analysis on the amino acid composition in membrane parts of 12 beta-barrel membrane proteins versus beta-strands of 79 all-beta soluble proteins. Expand

A Preliminary Attempt to Understand Compatibility of Photoplethysmographic Pulse Rate Variability with Electrocardiogramic Heart Rate Variability
We investigated the difference between heart rate variability (HRV) derived from electrocardiogramic (ECG) signals and pulse rate variability (PRV) derived from photoplethysmographic (PPG) signals.Expand

Describing the Nonstationarity Level of Neurological Signals Based on Quantifications of Time–Frequency Representation
TLDR
We introduced three different quantifications of TFR (qTFR) to characterize the nonstationarity level of the involving signals: 1) degree of stationarity (DS); 2) Shannon entropy (SE) of the marginal spectrum; and 3) Kullback-Leibler distance (KLD) between a TFR and a uniform distribution. Expand

Insight into the dicrotic notch in photoplethysmographic pulses from the finger tip of young adults
This study aims to investigate arterial stiffness in selected young adults by non-invasively determining the characteristics of the photoplethysmographic dicrotic notch. A total of 15 volunteersExpand

A HMM-based method to predict the transmembrane regions of \beta-barrel membrane proteins
TLDR
A novel method is developed to model and predict the transmembrane regions of beta-barrel membrane proteins known to date at atomic resolution with a jack-knife procedure. Expand

Influences of hypothermia on the cortical blood supply by laser speckle imaging.
Induced hypothermia has been broadly applied in neurological intensive care unit (NICU). Meanwhile, accidental hypothermia is also a threatening condition in daily life. It is meaningful toExpand

Object recognition under distorted prosthetic vision.
TLDR
In this study, we investigated how the objects were recognized under the stimuli with distorted phosphene arrays simulated by transformations of barrel distortion, rotation, or translation. Expand
