Physical Brownian motion in a magnetic field as a rough path
Transactions of the American Mathematical Society, 2015 The indefinite integral of the homogenized Ornstein-Uhlenbeck process is a well-known model for physical Brownian motion, modelling the behaviour of an object subject to random impulses [L. S. Ornstein, G. E.

Advanced Science, EarlyView.This study demonstrates a pump‐free, hydraulic‐amplification oscillatory microfluidic device, which generates oscillatory flows by deforming flexible microchannels through reciprocating finger pressing. The mechanism of elasto‐inertial focusing in the oscillatory flows is revealed, and early detection of drug‐treated platelet aggregates and rapid cell ...

Flow and Heat Transfer to Sisko Nanofluid over a Nonlinear Stretching Sheet.
PLoS ONE, 2015 The two-dimensional boundary layer flow and heat transfer to Sisko nanofluid over a non-linearly stretching sheet is scrutinized in the concerned study. Our nanofluid model incorporates the influences of the thermophoresis and Brownian motion.

Brownian motion in biological membranes.
Proceedings of the National Academy of Sciences of the United States of America, 1975 Brownian motion (diffusion) of particles in membranes occurs in a highly anisotropic environment. For such particles a translational mobility (independent of velocity) can be defined if the viscosity of the liquid embedding the membrane is taken into ...

Detecting non-Brownian trait evolution in adaptive radiations.
PLoS Biology, 2006 Many phylogenetic comparative methods that are currently widely used in the scientific literature assume a Brownian motion model for trait evolution, but the suitability of that model is rarely tested, and a number of important factors might affect ...
