  • Tabbal M.; Abi-Akl M.; Isber S.; Majdalani E.; Christidis T. (BELLINGHAM1000 20TH ST, PO BOX 10, BELLINGHAM, WA 98227-0010 USA, 2009)
    Manganese dioxide (MnO2) is considered as one of the most attractive compound among the manganese oxide phases due to its fundamental chemical and physical properties, its use in energy-storage devices, electrochemical ...

    Noncommutative geometry has been slowly emerging as a new paradigm of geometry which starts from quantum mechanics. One of its key features is that the new geometry is spectral in agreement with the physical way of measuring ...

    We study non-supersymmetric solutions of five dimensional N = 2 supergravity theories coupled to an arbitrary number of abelian vector multiplets. The solutions constructed can be considered as deformations of known ...

    Solutions of five-dimensional De Sitter supergravity admitting Killing spinors are considered, using spinorial geometry techniques. It is shown that the null solutions are defined in terms of a one parameter family of ...

    This review is concerned with the response of an isolated polymer chain subjected to the action of the two different modes of the mechanical impact on the chain ends. In one mode, the end-to-end distance is changed in a ...
  • El Eid M.F.; The L.-S.; Meyer B.S. (DORDRECHTVAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS, 2009)
    We present a general overview of the structure and evolution of massive stars of masses ≥12 M ⊙ during their pre-supernova stages. We think it is worth reviewing this topic owing to the crucial role of massive stars in ...
  • Antar G.Y.; Krasheninnikov S.I.; Snyder P.B.; Moyer R.A.; Pugno R.; Gray D.S. (VIENNAWAGRAMERSTRASSE 5, PO BOX 100, A-1400 VIENNA, AUSTRIA, 2009)
    The onset of type I edge localized modes (ELMs) is investigated on the DIII-D tokamak. A fast imaging camera is used with an integration time of 1 νs and a time between frames of about 15 νs continuously recording for a ...
  • Dimitrov D.I.; Klushin L.I.; Skvortsov A.; Milchev A.; Binder K. (NEW YORK233 SPRING ST, NEW YORK, NY 10013 USA, 2009)
    A flexible polymer chain under good solvent conditions, end-grafted on a flat repulsive substrate surface and compressed by a piston of circular cross-section with radius L may undergo the so-called escape transition when ...
  • Tremaine S.; Touma J.; Namouni F. (BRISTOLDIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND, 2009)
    The orbital dynamics of most planetary satellites is governed by the quadrupole moment from the equatorial bulge of the host planet and the tidal field from the Sun. On the Laplace surface, the long-term orbital evolution ...
  • Grover J.; Gutowski J.B.; Herdeiro C.A.R.; Sabra W. (AMSTERDAMPO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2009)
    Solutions of five-dimensional minimal de Sitter supergravity admitting Killing spinors are considered. It is shown that the timelike solutions are determined in terms of a four-dimensional hyper-Kähler torsion (HKT) manifold. ...

    We show that the algorithm proposed by Gauss to compute the secular evolution of gravitationally interacting Keplerian rings extends naturally to softened gravitational interactions. The resulting tool is ideal for the ...

    We consider the mechanical desorption of an infinitely long lattice polymer chain tethered at one end to an adsorbing surface. The external force is applied to the free end of the chain and is normal to the surface. There ...

    The exact partition of the gaussian chain squeezed between two cylinders for a phase transition in a single macromolecule is analyzed. The polymer chain is squeezed between two pistons which results in abrupt transition ...

    The local site symmetry of Ce3+ ions in the diluted magnetic semiconductors Pb1-x Cex A (A=S, Se, and Te) has been investigated by electron-paramagnetic resonance (EPR). The experiments were carried out on single crystals ...

    We classify half-supersymmetric solutions of gauged N = 2, D = 5 supergravity coupled to an arbitrary number of abelian vector multiplets for which all of the Killing spinors generate null Killing vectors. We show that ...
