Particle dynamics in sheared granular matter

W Losert, L Bocquet, TC Lubensky, JP Gollub - Physical review letters, 2000 - APS
The particle dynamics and shear forces of granular matter in a Couette geometry are determined
experimentally. The normalized tangential velocity V (y) declines strongly with distance …

[PDF][PDF] LTB4 is a signal-relay molecule during neutrophil chemotaxis

…, YJ Lee, CP McCann, CM Oliver, KA Aamer, W Losert… - Developmental cell, 2012 - cell.com
Neutrophil recruitment to inflammation sites purportedly depends on sequential waves of
chemoattractants. Current models propose that leukotriene B 4 (LTB 4 ), a secondary …

Granular shear flow dynamics and forces: Experiment and continuum theory

L Bocquet, W Losert, D Schalk, TC Lubensky… - Physical review E, 2001 - APS
We analyze the main features of granular shear flow through experimental measurements in
a Couette geometry and a comparison to a locally Newtonian, continuum model of granular …

Velocity statistics in excited granular media

W Losert, DGW Cooper, J Delour, A Kudrolli… - … Journal of Nonlinear …, 1999 - pubs.aip.org
We present an experimental study of velocity statistics for a partial layer of inelastic colliding
beads driven by a vertically oscillating boundary. Over a wide range of parameters (…

Survey on indirect optical manipulation of cells, nucleic acids, and motor proteins

AG Banerjee, S Chowdhury, W Losert… - Journal of biomedical …, 2011 - spiedigitallibrary.org
Optical tweezers have emerged as a promising technique for manipulating biological objects.
Instead of direct laser exposure, more often than not, optically-trapped beads are attached …

Small solar system bodies as granular media

…, L Staron, AC Bagatin, S Eggl, W Losert… - The Astronomy and …, 2019 - Springer
Asteroids and other Small Solar System Bodies (SSSBs) are of high general and scientific
interest in many aspects. The origin, formation, and evolution of our Solar System (and other …

Superstable granular heap in a thin channel

N Taberlet, P Richard, A Valance, W Losert, JM Pasini… - Physical review …, 2003 - APS
… a change in the channel width W. This indicates that the unusual … the SSH angle scales as
h=W (W being the channel width), … linear relation between the SSH angle and h=W (where W

[PDF][PDF] mTORC2 regulates neutrophil chemotaxis in a cAMP-and RhoA-dependent fashion

L Liu, S Das, W Losert, CA Parent - Developmental cell, 2010 - cell.com
We studied the role of the target of rapamycin complex 2 (mTORC2) during neutrophil
chemotaxis, a process that is mediated through the polarization of actin and myosin filament …

Invited article: Refractive index matched scanning of dense granular materials

…, F Rietz, KA Lőrincz, M Van Hecke, W Losert - Review of Scientific …, 2012 - pubs.aip.org
We review an experimental method that allows to probe the time-dependent structure of
fully three-dimensional densely packed granular materials and suspensions by means of …

Evolution of dendritic patterns during alloy solidification: Onset of the initial instability

W Losert, BQ Shi, HZ Cummins - Proceedings of the …, 1998 - National Acad Sciences
The evolution of a dendritic pattern from a planar solid–liquid interface during directional
solidification of a binary alloy was investigated experimentally. The model alloy used was the …
