Motion verbs and the expression of directed motion in English [PDF]
Bucharest Working Papers in Linguistics, 2011 Two commonly-held assumptions in the literature on the Goal of Motion construction in English are, on the one hand, that there is a clear-cut distinction between verbs of inherently directed motion and manner-of-motion verbs regarding their semantics, in

Detecting directed motion and confinement in single-particle trajectories using hidden variables [PDF]
eLifeSingle-particle tracking is a powerful tool for understanding protein dynamics and characterizing microenvironments. As the motion of unconstrained nanoscale particles is governed by Brownian diffusion, deviations from this behavior are biophysically ...

Neuronal Receptors Display Cytoskeleton-Independent Directed Motion on the Plasma Membrane [PDF]
iScience, 2018 Summary: Directed transport of transmembrane proteins is generally believed to occur via intracellular transport vesicles. However, using single-particle tracking in rat hippocampal neurons with a pH-sensitive quantum dot probe that specifically reports ...

Directed motion of liquid crystal skyrmions with oscillating fields [PDF]
New Journal of Physics, 2022 Using continuum simulations, we show that under a sinusoidal electric field, liquid crystal skyrmions undergo periodic shape oscillations which produce controlled directed motion. The speed of the skyrmion is non-monotonic in the frequency of the applied

Motion with Direction and Balance [PDF]
Neuron, 2014 In this issue of Neuron, three papers, Severi et al. (2014), Thiele et al. (2014), and Wang and McLean (2014), examine the descending circuitry involved in coordinating locomotor behavior in larval zebrafish. Visually evoked locomotor and steering movements in zebrafish are mediated by neurons in the nucleus of the medial longitudinal fascicle (nMLF ...

Royal Society Open Science, 2021 Active goal-directed motion requires real-time adjustment of control signals depending on the system’s status, also known as control. The amount of information that needs to be processed depends on the desired motion and control, and on the system’s ...

Active Brownian motion with directional reversals [PDF]
Physical Review E, 2021 Active Brownian motion with intermittent direction reversals are common in a class of bacteria like {\it Myxococcus xanthus} and {\it Pseudomonas putida}. We show that, for such a motion in two dimensions, the presence of the two time scales set by the rotational diffusion constant $D_R$ and the reversal rate $γ$ gives rise to four distinct dynamical ...

Chemophoresis engine: A general mechanism of ATPase-driven cargo transport.
PLoS Computational Biology, 2022 Cell polarity regulates the orientation of the cytoskeleton members that directs intracellular transport for cargo-like organelles, using chemical gradients sustained by ATP or GTP hydrolysis.

Complex Chromatin Motions for DNA Repair
Frontiers in Genetics, 2020 A number of studies across different model systems revealed that chromatin undergoes significant changes in dynamics in response to DNA damage. These include local motion changes at damage sites, increased nuclear exploration of both damaged and ...

Direct methods for recovering motion [PDF]
International Journal of Computer Vision, 1988 We have developed direct methods for recovering the motion of an observer in a static environment in the case of pure rotation, pure translation, and arbitrary motion when the rotation is known. Some of these methods are based on the minimization of the difference between the observed time derivative of brightness and that predicted from the spatial ...
