Indentation Of Ultrathin Elastic Films And The Emergence Of Asymptotic Isometry, Dominic Vella, Jianghui Huang, Narayanan Menon, Thomas P. Russell, Benny Davidovitch

Benny Davidovitch

We study the indentation of a thin elastic film floating at the surface of a liquid. We focus on the onset of radial wrinkles at a threshold indentation depth and the evolution of the wrinkle pattern as indentation progresses far beyond this threshold. Comparison between experiments on thin polymer films and theoretical calculations shows that the system very quickly reaches the far from threshold regime, in which wrinkles lead to the relaxation of azimuthal compression. Furthermore, when the indentation depth is sufficiently large that the wrinkles cover most of the film, we recognize a novel mechanical response in which the …

Neutron Generation From 10mev Electron Beam To Produce Mo99, Innovative Research Publications Irp India, Borhani Zarandi, Mahmood, Tabbakh, Farshid, Amrollahi Bioki, Hojjat

Innovative Research Publications IRP India

In this paper MCNP4C code has been used to simulate of the photonuclear interaction induced by 10MeV electron beam is an approach for generating the high intensity neutrons. Since the results are depended on the target material, the calculations are performed for the targets made of high z elements of Pb, Ta and W in a simple geometry.

Reviving Brontosaurus Name Because Of Species Differences, Life Throoughout The Precambrian As New Life Theory, Disproof Of Poincare Conjecture Because Meteorites Do Not Need To Map To Asteroid 3 Spheres Can Be From Comets, Planets, Oort Cloud, Kuiper Belt, Manifolds Changing And Moving Do Not Map To Unchanging 3 Spheres And I As Manifold Do Not Want To Be Folded Into 3 Sphere So Poincare Conjecture Disproven, James T. Struck

James T Struck

Three discoveries I made from visiting the Field Museum of Natural History yesterday on Illinois Day 12/6/2015. Brontosaurus as a dinosaur name can be brought back as existing in Wyoming rather than Apatosaurus' Colorado, 5 vertebrae rather than 3 on Apatosaurus, and larger size are enough to argue for a unique species. Yale Professor Marsh had it right when he saw Brontosaurus as different than Apatosaurus; larger size, different location, different bones should revive the Brontosaurus name. Riggs spoke to soon when speaking against Brontosaurus as a separate name. Second discovery, a new theory of life on Earth origin that …

Vortex Chains Due To Nonpairwise Interactions And Field-Induced Phase Transitions Between States With Different Broken Symmetry In Superconductors With Competing Order Parameters, Julien Garaud, Egor Babaev

Egor Babaev

We study superconductors with two order components and phase separation driven by intercomponent density-density interaction, focusing on the phase where only one condensate has nonzero ground-state density and a competing order parameter exists only in vortex cores. We demonstrate there that multibody intervortex interactions can be strongly nonpairwise, leading to some unusual vortex patterns in an external field, such as vortex pairs and vortex chains. We demonstrate that in an external magnetic field such a system undergoes a field-driven phase transition from (broken) U(1) to (broken) U(1)×U(1) symmetries when a subdominant order parameter in the vortex cores acquires global coherence. …

Spontaneous Breakdown Of Time-Reversal Symmetry Induced By Thermal Fluctuations, Johan Carlström, Egor Babaev

Egor Babaev

In systems with broken U(1) symmetry, such as superfluids, superconductors or magnets, the symmetry restoration is driven by proliferation of topological defects in the form of vortex loops. Here we discuss that in certain systems the proliferation of topological defects can, by contrast, lead to the breakdown of an additional symmetry. As a particular example we demonstrate that this effect should take place in s + is superconductors, which are widely discussed in connection with the Iron-based materials. In these systems a vortex excitation can create a “bubble" of fluctuating Z2 order parameter. Thermal excitation of vortices then leads to …

Moffatt Eddies In The Single Screw Extruder: Numerical And Analytical Study, Petru S. Fodor, Miron Kaufman

Miron Kaufman

A detailed analysis of the fluid flow in the single screw extruder is performed by combining numerical and analytical methods. While finite element analysis numerical models are used to extract the transversal velocity field, an analytical model in the limit of zero Reynolds numbers is used to determine the longitudinal component of the fluid velocities. The high resolution 3D model developed for the fluid flow in single screw extruders with aspect ratios (i.e. depth/width) ranging from 1 to 0.1, allows the identification of the position and extent of Moffatt eddies that impede the fluid mixing through the entire extruder’s volume. …
