Motion by Stopping: Rectifying Brownian Motion of Non-spherical Particles [PDF]
, 2007 We show that Brownian motion is spatially not symmetric for mesoscopic particles embedded in a fluid if the particle is not in thermal equilibrium and its shape is not spherical. In view of applications on molecular motors in biological cells, we sustain

Neuroanatomical correlates of biological motion detection [PDF]
Neuropsychologia, 2013 Biological motion detection is both commonplace and important, but there is great inter-individual variability in this ability, the neural basis of which is currently unknown. Here we examined whether the behavioral variability in biological motion detection is reflected in brain anatomy.

Brownian motion: a paradigm of soft matter and biological physics [PDF]
, 2005 This is a pedagogical introduction to Brownian motion on the occasion of the 100th anniversary of Einstein's 1905 paper on the subject. After briefly reviewing Einstein's work in its contemporary context, we pursue some lines of further developments and ...

Contributions of form, motion and task to biological motion perception [PDF]
Journal of Vision, 2009 The ability of human observers to detect 'biological motion' of humans and animals has been taken as evidence of specialized perceptual mechanisms. This ability remains unimpaired when the stimulus is reduced to a moving array of dots representing only the joints of the agent: the point light walker (PLW) (G. Johansson, 1973).

A Causal Role of the Right Superior Temporal Sulcus in Emotion Recognition From Biological Motion [PDF]
Open Mind, 2017 Understanding the emotions of others through nonverbal cues is critical for successful social interactions. The right posterior superior temporal sulcus (pSTS) is one brain region thought to be key in the recognition of the mental states of others based ...

Weak ergodicity breaking of receptor motion in living cells stemming from random diffusivity [PDF]
, 2015 Molecular transport in living systems regulates numerous processes underlying biological function. Although many cellular components exhibit anomalous diffusion, only recently has the subdiffusive motion been associated with nonergodic behavior.

Physically-interpretable classification of biological network dynamics for complex collective motions [PDF]
Scientific Reports, 10, 3005, 2020, 2019 Understanding biological network dynamics is a fundamental issue in various scientific and engineering fields. Network theory is capable of revealing the relationship between elements and their propagation; however, for complex collective motions, the network properties often transiently and complexly change.

Computing optical flow in the primate visual system [PDF]
, 1989 Computing motion on the basis of the time-varying image intensity is a difficult problem for both artificial and biological vision systems. We show how gradient models, a well-known class of motion algorithms, can be implemented within the magnocellular ...

Atomic Scale Fractal Dimensionality in Proteins [PDF]
, 2002 The soft condensed matter of biological organisms exhibits atomic motions whose properties depend strongly on temperature and hydration conditions. Due to the superposition of rapidly fluctuating alternative motions at both very low temperatures (quantum effects) and very high temperatures (classical Brownian motion regime), the dimension of an atomic `
