Abstract In this letter we study the local persistence of the two–dimensional Blume– Capel Model by extension of the concept of Glauber dynamics. We verify that for any value of the ratio α = D/J between anisotropy D and exchange J the persistence shows a power law behavior. In particular for α < 0 we find a persistence exponent θl = 0.2096(13), i.e. in the Ising universality class. For α > 0 (...

A statistical mechanical model for the switching mechanism of photoinduced magnetization is proposed making use of dynamics of magnetization in the circumstance with the metastable structure. As a typical model with metastability, the equilibrium and nonequilibrium properties of the Blume-Capel (BC) model have studied. We demonstrate reversible changes of magnetization corresponding to the chan...

This is a slightly longer version of an entry prepared for the 2nd edition of The New Palgrave Dictionary of Economics, edited by Steven Durlauf and Lawrence Blume (Palgrave-Macmillan, forthcoming). Since the New Palgrave does not include acknowledgments, I should use this chance to thank Roger Backhouse, Philippe Fontaine, Daniel Kahneman, Kyu Sang Lee, Ivan Moscati, and Vernon Smith for their...

From the roots of Myxopyrum smilacifolium Blume, five known compounds, verbascoside (1), arenarioside (2), myxopyroside (3), 3-formylindole (4), and 5-hydroxymethyl furfural (5) were isolated. Their chemical structures determined by ESI-MS, 1D, 2D-NMR spectrascopic data analysis as well in comparison with those reported literatures.

Abstract We exhibit a class of integer spin systems whose free energy can be written in term of an absolutely convergent series at any temperature. This class includes spin systems on Z interacting through infinite range pair potential polynomially decaying at large distances r at a rate 1/r with ε > 0. It also contains the Blume-Emery-Griffiths model in the disordered phase at large values of ...

We have studied by means of Monte-Carlo simulation and exact finite-size analysis, the spin-1 Blume Capel model with Glauber and Kawasaki dynamics. The Kawasaki spin exchange process flows energy into the system from an external source. Some phase diagrams of the model are presented. For some values of the parameters, the system displays a kind of self organization phenomenon within the disorde...

Two new phytoecdysteroids, (25S)-20,22-O-(R-ethylidene)inokosterone and 20,22-O-(R-3-methoxycarbonyl)propylidene-20-hydroxyecdysone, together with six known phytoecdysteroids 3-8 were isolated from the roots of Achyranthes bidentata Blume. The new structures were established on the basis of spectroscopic studies and chemical evidences. The absolute configuration at C-25 in the structure of know...
