We investigate the effect of loading rate on drainage in molecularly thin films of a simple fluid made of quasispherical molecules [octamethylcyclotetrasiloxane (OMCTS)]. We find that (i) rapidly confined OMCTS retains its tendency to organize into layers parallel to the confining surfaces, and (ii) flow resistance in such layered films can be described by bulklike viscous forces if one account...

In the Drosophila ventral nerve cord, a small number of neurons express the LIM-homeodomain gene apterous (ap). These ap neurons can be subdivided based upon axon pathfinding and their expression of neuropeptidergic markers. ap, the zinc finger gene squeeze, the bHLH gene dimmed, and the BMP pathway are all required for proper specification of these cells. Here, using several ap neuron terminal...

New Mg-3Zn-2Ca magnesium alloy was prepared using different processing techniques: gravity casting as well as squeeze casting in liquid and semisolid states. Materials were further thermally treated; thermal treatment of the gravity cast alloy was additionally combined with the equal channel angular pressing (ECAP). Alloy processed by the squeeze casting in liquid as well as in semisolid state ...

The equation of state (EOS) of asymmetric nuclear matter is of fundamental importance to both nuclear physics and astrophysics. While considerable progress has been made recently in determining the symmetry energy around normal nuclear matter density [1], much more work is still needed to probe its high-density behaviour. This requires reaction studies at sufficiently high energies and probes s...

Y ou drive differently on narrow streets than you do on an open stretch of highway. Similarly, migrating cells rely on different movement mechanisms depending on whether they have ample space or are in cramped conditions, Hung et al. reveal (1). In the body, migrating cells usually must slither through spaces in the extracellular matrix or slip through narrow channels that run between connectiv...

Aim of this work was to test the idea of J.-Y.Ollitrault about the parallel squeeze-out type of transversal flow in mid-rapidity region [1]. For this purpose we have performed a computer simulation of the expanding pion gas created in non-central Pb-Pb 158GeV/n collisions. A squeeze-out type of asymmetry parallel to impact parameter in az-imuthal distribution of pions is found and studied. The ...

One hundred years ago, in 1908, Hermann Minkowski completed his proof that Maxwell’s equations are covariant under Lorentz transformations. During this process, he introduced a four-dimensional space called the Minkowskian space. In 1949, P. A. M. Dirac showed the Minkowskian space can be handled with the light-cone coordinate system with squeeze transformations. While the squeeze is one of the...

We present an easy-to-use toolbox for the automated generation of reduced-order mixed-level models for the evaluation of squeeze-film damping in microelectromechanical systems. The toolbox is programmed in JAVA and heavily exploits the functionality provided by the COMSOL API. The results obtained from mixed-level model simulation performed in COMSOL Multiphysics agree very well with experiment...
