Viscosity Dependence Rotational Reorientation Rhodamine B Mono-and Poly-alcohols
2016/5/20
Rotational reorientationtimes (TROT)were obtained for rhodamine B in a series of n-alcoholsand polyalcohols of varying viscositiesby a transient grating technique. The general trend of the Debye-Stoke...
Dependence of the Yield of a Radical-Pair Reaction in the Solid State on Orientation in a Magnetic Field
Radical-Pair Reaction Solid State on Orientation Magnetic Field
2016/5/20
We report the observation that the yield of a radical-pair reaction in the solid state can depend strongly on the orientation of the reactants in a magnetic field. This phenomenon is expected to be qu...

We consider two alternative tests to the Higher Criticism test of Donoho and Jin (2004) for high dimensional means under the spar-sity of the non-zero means for sub-Gaussian distributed data with unkn...
This paper discusses the correlation structure between London Interbank Offered Rates (LIBOR) by using copula function. We start from one simplified model of Brace, Gatarek & Musiela (1997) and find o...
Weighted Estimation of the Dependence Function for an Extreme-Value Distribution
