The dynamics of Lennard-Jones fluid is studied through extended mode coupling theory (MCT) with the inclusion of the slow mode of defect density. Inclusion of defect density facilitates the liquid like state for temperatures much lower than predicted from ideal MCT. From the present model the temperature dependence of the power law exponent is obtained at a constant pressure. We have also compu...

In this paper we investigate quantitatively statistical properties of ensemble of land prices in Japan in the period from 1981 to 2002, corresponding to the period of bubbles and crashes. We find that the tail of the distributions of ensembles of the land prices in the high price range is well described by a power law distribution, P (S > x) ∼ x−α, and furthermore that as the power-law exponent...

We have measured the electrical conductance and thermopower of a single InSb nanowire in the temperature range from 5 to 340 K. Below temperature (T ) 220 K, the conductance (G) shows a power-law dependence on T and the current (I )–voltage (V ) curve follows a power-law dependence on V at large bias voltages. These features are the characteristics of one-dimensional Luttinger liquid (LL) trans...

The angular power spectrum of H I 21 cm opacity fluctuations is a useful statistic for quantifying the observed opacity fluctuations as well as for comparing these with theoretical models. We present here the H I 21 cm opacity fluctuation power spectrum towards the supernova remnant Cas A from interferometric data with spacial resolution of 5 arcsec and spectral resolution of 0.4 km s−1. The po...

In this study we investigate quantitatively statistical properties of an ensemble of land prices in Japan in the period from 1981 to 2002, corresponding to a period of bubbles and crashes. We found that the tail of the complementary cumulative distribution function of the ensemble of land prices in the high price range is well described by a power-law distribution, P (S > x) ∼ x−α, and furtherm...

Power-law distributions have been a paradigm of complex systems for several decades. But it has been only recently that attention has been devoted to the proper fitting and goodness-of-fit testing of these distributions; in particular, Clauset et al.’s method is widely cited in this regard [1]. In the first part of the talk we present evidence that this method fails in some concrete examples of...

We present experimental heat transport measurements of turbulent Rayleigh-Bénard convection with rotation about a vertical axis. The fluid, water with a Prandtl number (sigma) of about 6, was confined in a cell with a square cross section of 7.3 x 7.3 cm2 and a height of 9.4 cm. Heat transport was measured for Rayleigh numbers 2 x 10(5)<Ra<5 x 10(8) and Taylor numbers 0<Ta<5 x 10(9). We show th...

Abstract We attempt to model magnetic reconnection during the two-ribbon flare in a gravitationally stratified solar atmosphere with Lundquist number of S = 10 6 using 2D simulations. found that tearing mode instability leads inhomogeneous turbulence inside reconnecting current sheet (CS) and invokes fast phase reconnection. Fast brings an extra dissipation field which enhances rate apparent wa...

We present a GRANAT/SIGMA observation of the soft gamma-ray afterglow immediately after GRB 920723. The main burst is very bright. After 6 s, the burst light curve makes a smooth transition into an af-terglow where ux decays as t ?0:7. The power-law decay lasts for at least 1000 s; beyond this time, the afterglow emission is lost in the background uctuations. At least 20% of main burst energy i...
