156. On mechanism of enhanced flourescence in green flourescent protein

Author

Starikov, E. B., Panas, I., Mochizuki, Y., Tanaka, S., Luo, Yi, Ågren, Hans, Starikov, E. B., Panas, I., Mochizuki, Y., Tanaka, S., Luo, Yi, and Ågren, Hans

Abstract

In spite of the numerous experimental and theoretical studies on green fluorescent protein and its modifications, there is still no definitive answer to the central question: why such systems exhibit enhanced fluorescence. Based upon detailed quantum-chemical estimations, we advocate the following hypothesis. In the green fluorescent protein ground electronic state, the protein surrounding strains the chromophore with respect to its native intramolecular conformational preference in vacuo or in solution. Absorbing a photon of the proper wavelength not only causes a joint proton-electron transfer in and around the chromophore, but also increases the intrinsic strain of the latter. Since conformational relaxation of such a structure will not require any additional energy input, the energy gained by the chromophore cannot be dissipated into the chromophore's internal non-radiative degrees of freedom, and thus it returns as a fluorescence emission., QC 20141104

169. Size, order, and dimensional relations for silicon cluster polarizabilities

Author

Jansik, B, Schimmelpfennig, B, Norman, Patrick, Mochizuki, Y, Luo, Y, Agren, H, Jansik, B, Schimmelpfennig, B, Norman, Patrick, Mochizuki, Y, Luo, Y, and Agren, H

Abstract

Response theory calculations in the random phase approximation are applied to linear polarizabilities and second hyperpolarizabilities of 1-, 2-, and 3-dimensional hydrogen-terminated silicon clusters. Successive enlargement of the clusters to embody on the order of 50 silicon atoms plus bond-saturating hydrogen atoms allows for extrapolation to bulk values of individual silicon atom contributions in the 1D and 3D cases. Modern effective core potentials are shown to provide excellent approximations to the all-electron values in all cases, errors for both polarizabilities and hyperpolarizabilities are on the order of 1%. The findings indicate considerable time savings in predictions of the electric polarizability properties of elements beyond the first row atoms.

175. Polarizability of silicon clusters

Author

Mochizuki, Y., Ågren, Hans, Mochizuki, Y., and Ågren, Hans

Abstract

The polarizability of hydrogen-terminated silicon dusters derived from the silicon diamond-lattice structure was evaluated by linear response calculations. The dependences on cluster size and basis set were systematically investigated. A convergence in calculated polarizability per silicon atom toward the bulk value was found. Frequency-dependent polarizabilities were also addressed., QC 20100525

195. Computing the Local Continuity Order of Optical Flow Using Fractional Variational Method.

Author

Kashu, K., Kameda, Y., Imiya, A., Sakai, T., and Mochizuki, Y.

Abstract

We introduce variational optical flow computation involving priors with fractional order differentiations. Fractional order differentiations are typical tools in signal processing and image analysis. The zero-crossing of a fractional order Laplacian yields better performance for edge detection than the zero-crossing of the usual Laplacian. The order of the differentiation of the prior controls the continuity class of the solution. Therefore, using the square norm of the fractional order differentiation of optical flow field as the prior, we develop a method to estimate the local continuity order of the optical flow field at each point. The method detects the optimal continuity order of optical flow and corresponding optical flow vector at each point. Numerical results show that the Horn-Schunck type prior involving the n + ε order differentiation for 0 < ε< 1 and an integer n is suitable for accurate optical flow computation.
