In previous work Majda and McLaughlin, and Majda computed explicit expressions for the 2Nth moments of a passive scalar advected by a linear shear flow in the form of an integral over RN. In this… (More)

Preparation and the valuable anti-inflammatory and antibiotic properties of substituted sydnones, represented by the formula WHEREIN R is hydrogen, lower alkyl, phenyl or bromo, Alk is alkylene… (More)

Many microfluidic systems—including chemical reaction, sample analysis, separation, chemotaxis, and drug development and injection—require control and precision of solute transport. Although… (More)

Recently, one of the authors, studying a model for turbulent diffusion involving a large‐scale velocity field rapidly fluctuating in time, rigorously demonstrated intermittency in a diffusing scalar… (More)

Recent studies of a passive scalar diffusing in a rapidly fluctuating Gaussian distributed linear shear layer have demonstrated intermittency in the form of broad tails and non‐symmetric limiting… (More)

We present experimental observations and quantified theoretical predictions of the nanoscale hydrodynamics induced by nanorod precession emulating primary cilia motion in developing embryos. We… (More)

Abstract An enormous and important theoretical effort has been directed at studying the origin of broad-tailed probability distribution functions observed for numerous physical quantities measured in… (More)

We study the role geometry plays in the emergence of asymmetries in diffusing passive scalars advected by pressure-driven flows in ducts and pipes of different aspect ratios. We uncover nonintuitive,… (More)

Enhanced diffusion coefficients arising from the theory of periodic homogenized averaging for a passive scalar diffusing in the presence of a large-scale, fluctuating mean wind superimposed upon a… (More)
