We report molecular dynamics results for the contact values of the radial distribution functions of binary additive mixtures of hard disks. The simulation data are compared with theoretical predictions from expressions proposed by Jenkins and Mancini [J. Appl. Mech. 54, 27 (1987)] and Santos et al. [J. Chem. Phys. 117, 5785 (2002)]. Both theories agree quantitatively within a very small margin,...

Zusammenfassung. Als Erweiterung und Ergänzung bisheriger kernspint omographischer Aufnahmetechniken liefert die neu entwickelte Magnetres onanzelastographie (MRE) Bildinformationen, die eine Bestimmung der m echanischen Eigenschaften des Untersuchungsobjektes ermöglichen. Die MRE erlaubt erstmals, Veränderungen biomechanischer Gewebeeigenschaften, die als Folge pathologischer Veränderungen auf...

A new paradigm of rheological characterization, oscillatory simple shear with infinite forcing amplitudes, is introduced by Khair (J. Fluid Mech., vol. 791, 2016, R5). This pushes the technique of large-amplitude oscillatory shear (LAOS) to have two extremely large amplitudes (both strain-rate and strain), which we might call XXLAOS. Model-specific analytical predictions are derived for a suspe...

The evolution of a small but nite three-dimensional disturbance on a at uniform vortex sheet is studied numerically on the basis of a Lagrangian representation of the motion. The numerical simulations connrm the asymptotic analysis by Ishihara and Kaneda (1995; J. Fluid Mech., 300, 339-366) for the spontaneous singularity formation in the shape of the vortex sheet. They also suggest that the si...

We establish a connection between optimal transport theory (see Villani in Topics in optimal transportation. Graduate studies in mathematics, vol. 58, AMS, Providence, 2003, for instance) and classical convection theory for geophysical flows (Pedlosky, in Geophysical fluid dynamics, Springer, New York, 1979). Our starting point is the model designed few years ago by Angenent, Haker, and Tannenb...

M. S. Howe J. Fluid Mech. 206, 131 1989 presented integral formulas for the force and torque on a rigid body that permit the identification of the separate influences of added mass, normal stresses induced by free vorticity, and viscous skin friction. Here a simple extension of Howe’s formulas is done for systems of several rigid bodies. The goal is to separate these effects on each rigid body....

Although the phenomenon of acquired resistance has come to play a major role in studies of mechanism of ac tion and in the design of new chemotherapeutic agents, the development of knowledge about collateral sensitivity has received far less attention. Yet this feature of the complex changes which accompany conversion to drug resistance is potentially of importance to chemotherapy, as well as t...

We have found evidence for a bolide impacting Earth in the mid-Devonian ( approximately 380 million years ago), including high concentrations of shocked quartz, Ni, Cr, As, V, and Co anomalies; a large negative carbon isotope shift (-9 per mil); and microspherules and microcrysts at Jebel Mech Irdane in the Anti Atlas desert near Rissani, Morocco. This impact is important because it is coincide...

In this paper the totally asymmetric exclusion process (TASEP) with parallel update on an open lattice of size L is considered in the maximum-current region. A formal expression for the generating function for the weight of configurations with N particles is given. Further an interpretation in terms of (u, l, d)-colored weighted Motzkin paths is presented. Using previous results (Woelki and Sch...

This paper is devoted to studying the temperature-dependent incompressible nematic liquid crystal flows in a bounded domain Ω ⊂ R (N = 2, 3). Inspired by Danchin [J. Math. Fluid Mech. 2006], we use a localization argument to recover the maximal regularity of Stokes equation with variable viscosity. Also the results proved by Lei-Li-Zhang [Proc. Amer. Math. Soc. 2014] are generalized to the case...
