Modeling Reverse-Phi Motion-Selective Neurons in Cortex: Double Synaptic-Veto Mechanism [PDF]
Neural Computation, 2003 Reverse-phi motion is the illusory reversal of perceived direction of movement when the stimulus contrast is reversed in successive frames. Livingstone, Tsao, and Conway (2000) showed that direction-selective cells in striate cortex of the alert macaque monkey showed reversed excitatory and inhibitory regions when two different contrast bars were ...

3D Motion Simulation of Engineering Equipment Working Mechanism Based on Reverse Drive Mode
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The working mechanism of engineering equipment has a relatively complicated structure which contains many kinematical pairs, its 3D motion simulation is a difficult problem. Based on the reverse drive mode linked by forward kinematics, 3D motion simulation model of working mechanism is analysed, and the kinematic chains are ...

Analysis of the reversing mechanism of light industry equipment
Trudy Odesskogo Politehničeskogo Universiteta, 2021 To create reliable and highly efficient, en- ergy-saving machines for light industry, it is necessary to study the dynamic processes of movement of the links of the mechanisms of which they are composed. Especially such studies should be given attention

Journal of Marine Science and Engineering, 2023 In this paper, to effectively solve the joint motion planning of a nine-DOF redundant hybrid boarding system in the process of ocean wave active compensation, we present a multi-task motion planning (MTMP) method for the redundant hybrid boarding system.

The Neural Circuit Mechanisms Underlying the Retinal Response to Motion Reversal [PDF]
The Journal of Neuroscience, 2014 To make up for delays in visual processing, retinal circuitry effectively predicts that a moving object will continue moving in a straight line, allowing retinal ganglion cells to anticipate the object's position. However, a sudden reversal of motion triggers a synchronous burst of firing from a large group of ganglion cells, possibly signaling a ...

A Novel Piezo Inertia Actuator Inspired by Motion Mode of Steam Train’s Transmission Mechanism
IEEE Access, 2023 Previously reported inertia actuators mostly have the problem of greater deviations between positive and reverse speeds. To solve this problem, we have developed a novel piezo inertia actuator with a similar structure, inspired by the motion mode of the ...

Two motion perception mechanisms revealed through distance-driven reversal of apparent motion [PDF]
Proceedings of the National Academy of Sciences, 1989 We demonstrate two kinds of visual stimuli that exhibit motion in one direction when viewed from near and in the opposite direction from afar. These striking reversals occur because each kind of stimulus is constructed to simultaneously activate two different mechanisms: a short-range mechanism that computes motion from space-time correspondences in ...

Design and Analysis of a Stepping Piezoelectric Actuator Free of Backward Motion
Actuators, 2021 Although the stick-slip principle has been widely employed for designing piezoelectric actuators, there still exits an intrinsic drawback, i.e., the backward motion, which significantly affects its output performances and applications.
