Spatial resolution and receptive field height of motion sensors in human vision [PDF]

open access: yes, 2000
We estimated the length of motion-detecting receptive fields in human vision by measuring direction discrimination for three novel stimuli. The motion sequences contained either (i) alternate frames of two differently oriented sinusoidal gratings; (ii ...

Advancing Human Skin Equivalents: The Crucial Role of Neurovascular Integration

open access: yesAdvanced Healthcare Materials, EarlyView.
This review discusses the importance of integrating vascular and peripheral nerve systems into human skin equivalents (HSEs) to better recapitulate native skin physiology. Recent advances in vascularized, innervated, and neurovascularized HSEs are highlighted, together with emerging bioengineering strategies, current challenges, and future ...

Stretchable Microelectrode Arrays for Electro‐Mechanical Probing of Brain Spheroids

open access: yesAdvanced Healthcare Materials, EarlyView.
A multimodal device featuring kirigami‐patterned stretchable microelectrode arrays enables concurrent mechanical actuation and electrophysiological recording of brain spheroids. The platform supports multiple loading regimes and reveals mechanically induced modulation of spontaneous network activity in 3D neural tissue models.

Torsional Response Induced by Lateral Displacement and Inertial Force

open access: yesFrontiers in Built Environment, 2018
Eccentric distribution of stiffness, damping, and mass of a structure, and spatially non-uniform ground motion input to a long or large base mat of a structure are well-known causes of torsional response.

Motion perception during sinusoidal smooth pursuit eye movements: signal latencies and non-linearities [PDF]

open access: yes, 2008
Smooth pursuit eye movements add motion to the retinal image. To compensate, the visual system can combine estimates of pursuit velocity and retinal motion to recover motion with respect to the head.

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

open access: yesAdvanced Materials, EarlyView.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...

Effect of Side-Walls on Flapping-Wing Power-Generation: an Experimental Study

open access: yesJournal of Applied Fluid Mechanics, 2016
Effect of constrained flow is investigated experimentally for a flapping foil power-generator. The flow structures around and in the near wake of a flat plate placed between two side walls are captured via PIV technique with simultaneous direct force ...

Head vibration increases the benefits relative to the risks of immersive virtual reality

open access: yesComputers in Human Behavior Reports
Immersive experiences in virtual reality (VR) have traditionally been associated with graphical displays, but any system that artificially stimulates any of our senses can potentially simulate experiences of the real world. Recent studies have shown that

Contour accuracy improvement of a flexure-based micro-motion stage for tracking repetitive trajectory

open access: yesAIP Advances, 2017
Flexure-based micro-motion mechanisms have been widely utilized in modern precision industry due to their inherent merits, while model uncertainty, uncertain nonlinearity, and cross-coupling effect will obviously deteriorate their ...
