Inversion formula of multifractal energy dissipation in 3D fully developed turbulence
The concept of inverse statistics in turbulence has attracted much attention
in the recent years. It is argued that the scaling exponents of the direct
structure functions and the inverse structure functions satisfy an inversion
formula. This proposition has already been verified by numerical data using the
shell model. However, no direct evidence was reported for experimental three
dimensional turbulence. We propose to test the inversion formula using
experimental data of three dimensional fully developed turbulence by
considering the energy dissipation rates in stead of the usual efforts on the
structure functions. The moments of the exit distances are shown to exhibit
nice multifractality. The inversion formula between the direct and inverse
exponents is then verified.Comment: 3 RevTex pages including 3 eps figure
4-(2-Hydroxybenzylideneamino)benzonitrile
The molecule of the title compound, C14H10N2O, is nearly planar. There is a strong intramolecular O—H⋯N hydrogen bond between the imine and hydroxy groups. The configuration with respect to the C=N double bond is anti (1E)
Multimode Brownian oscillators: Thermodynamics and heat transport
In this work, we investigate the multimode Brownian oscillators in
nonequilibrium scenarios with multiple reservoirs at different temperatures.
For this purpose, an algebraic method is proposed. This approach directly gives
the exact time-local equation of motion for reduced density operator, from
which we can easily extract both the reduced system and hybrid bath dynamical
informations. Two representative entangled system-bath quantities, the heat
transport and the thermodynamics of quantum mixing, are studied. The heat
current is obtained from both the algebraic method and the discrete
imaginary-frequency method followed by the Meir-Wingreen's formula. It is
anticipated that the algebraic method developed in this work would constitute a
crucial component for nonequilibrium statistical mechanics for open quantum
systems.Comment: SM adde
3-[4-(Dimethylamino)benzylideneamino]benzonitrile
The molecule of the title Schiff base, C16H15N3, is non-planar and displays a trans configuration with respect to the C=N double bond. The two benzene rings make a dihedral angle of 49.24 (3)°
3-(2-Hydroxybenzylideneamino)benzonitrile
In the title molecule, C14H10N2O, an intramolecular O—H⋯N hydrogen bond contributes to the essential coplanarity of the two benzene rings, which form a dihedral angle of 6.04 (18)°
Bis[2-(3-cyanophenyliminomethyl)phenolato]nickel(II)
In the title complex, [Ni(C14H9N2O)2], the NiII atom lies on an inversion center and is coordinated by the O atom and an N atom of two Schiff base 2-(3-cyanophenyliminomethyl)phenolate ligands in a square-planar geometry. The dihedral angle between the cyanophenyl and phenolate rings is 47.62 (7)°
