Thermally Driven Elastic Micromachines
We discuss the directional motion of an elastic three-sphere micromachine in which the spheres are in equilibrium with independent heat baths having different temperatures. Even in the absence of prescribed motion of springs, such a micromachine can gain

Estimating Sensor Motion from Wide-Field Optical Flow on a Log-Dipolar Sensor [PDF]
Log-polar image architectures, motivated by the structure of the human visual field, have long been investigated in computer vision for use in estimating motion parameters from an optical flow vector field. Practical problems with this approach have been:

A computational model for motion detection and direction discrimination in humans [PDF]
Seeing biological motion is very important for both humans and computers. Psychophysics experiments show that the ability of our visual system for biological motion detection and direction discrimination is different from that for simple translation. The

Autistic traits relate to reduced reward sensitivity in learning from point-light displays (PLDs)
A number of studies have linked autistic traits to difficulties in learning from social (versus non-social) stimuli. However, these stimuli are often difficult to match on low-level visual properties, which is especially important given the impact of ...

Spike to Spike Model and Applications: A biological plausible approach for the motion processing [PDF]
We propose V1 and MT functional models for biological motion recognition. Our V1 model transforms a video stream into spike trains through local motion detectors. The spike trains are the inputs of a spiking MT network.

Mucus and ciliated cells of human lung : splitting strategies for particle methods and 3D stokes flows [PDF]
Lung walls are covered by a film of mucus, whose motility is fundamental for a healthy behavior. Indeed, mucus traps inhaled aerosols (bacteria, dust, ...), and moves from smallest to largest airways, until it reaches esophagus where is it swallowed or ...

Size-scaling limits of impulsive elastic energy release from a resilin-like elastomer
Elastically-driven motion has been used as a strategy to achieve high speeds in small organisms and engineered micro-robotic devices. We examine the size-scaling relations determining the limit of elastic energy release from elastomer bands with ...

Multi-level processing of emotions in life motion signals revealed through pupil responses
Perceiving emotions from the movements of other biological entities is critical for human survival and interpersonal interactions. Here, we report that emotional information conveyed by point-light biological motion (BM) triggered automatic physiological

Motion estimation: A biologically inspired model
When humans (or robots) move through a scene, the scene can be represented as an optic flow (optical flow) field that contains vectors representing all of the movement within the scene projected onto a two-dimensional sensor. A simultaneous sample of these resulting vectors contain a good deal of information.
