Actively stressed marginal networks [PDF]

open access: yes, 2012
We study the effects of motor-generated stresses in disordered three dimensional fiber networks using a combination of a mean-field, effective medium theory, scaling analysis and a computational model.

Fluctuating Motor Forces Bend Growing Microtubules [PDF]

open access: yesCellular and Molecular Bioengineering, 2013
Despite their rigidity, microtubules in living cells bend significantly during polymerization resulting in greater curvature than can be explained by thermal forces alone. However, the source of the non-thermal forces that bend growing microtubules remains obscure. We analyzed the motion of microtubule tips in NIH-3T3 fibroblasts expressing EGFP-EB1, a

Single-Phase Induction Motor Under Voltage Fluctuations

open access: yesScientific Journal of Gdynia Maritime University, 2022
Some of the most common power quality disturbances are voltage fluctuations. They are interconnected with the presence of voltage subharmonics and interharmonics.

How Wearable Sensors Can Support Parkinson's Disease Diagnosis and Treatment: A Systematic Review

open access: yesFrontiers in Neuroscience, 2017
Background: Parkinson's disease (PD) is a common and disabling pathology that is characterized by both motor and non-motor symptoms and affects millions of people worldwide. The disease significantly affects quality of life of those affected.

Automatic Spiral Analysis for Objective Assessment of Motor Symptoms in Parkinson’s Disease

open access: yesSensors, 2015
A challenge for the clinical management of advanced Parkinson’s disease (PD) patients is the emergence of fluctuations in motor performance, which represents a significant source of disability during activities of daily living of the patients. There is a

Fluctuation Relations for Molecular Motors [PDF]

open access: yes, 2010
This review is focused on the application of specific fluctuation relations, such as the Gallavotti-Cohen relation, to ratchet models of a molecular motor. A special emphasis is placed on two-states models such as the flashing ratchet model. We derive the Gallavotti-Cohen fluctuation relation for these models and we discuss some of its implications.

Rectifying fluctuations in an optical lattice [PDF]

open access: yes, 2004
We have realized a Brownian motor by using cold atoms in a dissipative optical lattice as a model system. In our experiment the optical potential is spatially symmetric and the time-symmetry of the system is broken by applying appropriate zero-mean ac ...

Hitchhiking Through the Cytoplasm [PDF]

open access: yes, 2006
We propose an alternative mechanism for intracellular cargo transport which results from motor induced longitudinal fluctuations of cytoskeletal microtubules (MT).
