The effect of forcing on the spatial structure and spectra of chaotically advected passive scalars
, 1999 The stationary distribution of passive tracers chaotically advected by a two-dimensional large-scale flow is investigated. The tracer field is force by resetting the value of the tracer in certain localised regions.

DSi as a Tracer for Submarine Groundwater Discharge
Frontiers in Marine Science, 2019 Submarine groundwater discharge (SGD) is an important source of nutrients and metals to the coastal ocean, affects coastal ecosystems, and is gaining recognition as a relevant water resource.

Collective dynamics effect transient subdiffusion of inert tracers in gel networks
, 2014 Based on extensive Brownian dynamics simulations we study the thermally driven motion of a tracer bead in a cross-linked, dynamic gel network in the limit when the tracer bead's size is of the same size or even larger than the equilibrium mesh size of ...

Axons Giving Rise to the Palisade Endings of Feline Extraocular Muscles Display Motor Features [PDF]
, 2013 Palisade endings are nerve specializations found in the extraocular muscles (EOMs) of mammals, including primates. They have long been postulated to be proprioceptors. It was recently demonstrated that palisade endings are cholinergic and that in monkeys

Stirring by Periodic Arrays of Microswimmers [PDF]
, 2016 The interaction between swimming microorganisms or artificial self-propelled colloids and passive (tracer) particles in a fluid leads to enhanced diffusion of the tracers. This enhancement has attracted strong interest, as it could lead to new strategies

Toxicity of fluorescent tracers and their degradation byproducts
International Journal of Speleology, 2017 Tracer tests are frequently used to delineate catchment area of water supply springs in karstic zones. In the karstic chalk of Normandy, the main tracers used are fluorescent: uranine, sulforhodamine B, naphtionate, and Tinopal®.

Effects of structural relaxation on cationic tracer diffusion in silicate melts [PDF]
, 1989 The glass transition in silicate melts is a curve in time-temperature space marking the transition of the melt structure from an unrelaxed, disequilibrium glass to a relaxed, equilibrium liquid. Tracer diffusivity data obtained in glasses vs.

Nonequilibrium fluctuations and enhanced diffusion of a driven particle in a dense environment [PDF]
, 2018 We study the diffusion of a tracer particle driven out-of-equilibrium by an external force and traveling in a dense environment of arbitrary density. The system evolves on a discrete lattice and its stochastic dynamics is described by a master equation ...
