Predictive coding feedback results in perceived illusory contours in a recurrent neural network [PDF]
arXiv, 2021 Modern feedforward convolutional neural networks (CNNs) can now solve some computer vision tasks at super-human levels. However, these networks only roughly mimic human visual perception. One difference from human vision is that they do not appear to perceive illusory contours (e.g. Kanizsa squares) in the same way humans do.

Advanced Science, EarlyView.A wearable hyperspectral photoplethysmography (HS‐PPG) is reported for continuous blood pressure (BP) monitoring. The HS‐PPG module integrates an ultrathin double‐folded solid immersion grating microspectrometer (DFSIG‐µSPEC), achieving a high spectral resolution of 3.4 nm.

Discrete two-countour system with one-directional motion [PDF]
arXiv, 2021 This paper studies a dynamical system, which contains two contours. There is a cluster on each contour. The cluster contains particles, located in adjacent cells. The clusters move under prescribed rules. The delays of clusters are due to that the clusters cannot pass through the node simultaneously. The dynamical system belongs to the class of contour

A Touch Enabled Hemodynamic and Metabolic Monitor
Advanced Science, EarlyView.This work presents a touch‐based hybrid platform for simultaneous monitoring of vital signs and sweat metabolites. With a simple tri‐finger touch of 4–6 min, users can concurrently get to know their glucose, uric acid, cortisol levels from fingertip sweat, along with blood pressure and heart rate.

Aging Cell, EarlyView.The effect of advancing age and intraocular pressure injury on retinal ganglion cell function and synaptic connectivity. While young mice modulate their synaptic input to recover retinal ganglion cell function following injury, older mice compensate by altering their action potential threshold and axon initial segment (AIS) length to increase intrinsic
