We show, using the methods of geometric algebra, that Runge–Lenz vector in the Kepler problem is a 3-dimensional projection of SO(4) moment map that acts on the phase space of 4-dimensional particle motion. Thus, Runge–Lenz vector is a consequenc

The Heavy Quark Effective Theory provides a systematic method to estimate a mixing angles of hadron states in a heavy quark, such as charm quark (c) and bottom quark (b). Using this method, we can estimate the mixing angles of the baryons Ξ Q − Ξ

We analyzed the functional structure of Streptococcus bovis 148 α-amylase (AmyA) to determine the starch binding domain (SBD) of this enzyme. Several derivative AmyAs and putative SBD segments were constructed and assayed their adsorption ability on

R-755 (N-(2,6-diethylphenyl)-#’-[3-(2-methylphenyl)-6,7-dihydro-5H-cyclopenta[f][l]benzo-thiophen-2-yl]urea), a novel acyl-CoA:cholesterol acyltransferase (ACAT) inhibitor, has been characterized in vitro, ex vivo and in vivo. R-755 potently inhibi

In the case of two generation neutrinos, the energy-scale dependence of the lepton-flavor mixing matrix with Majorana phase can be governed by only one parameter r, which is the ratio between the diagonal elements of neutrino mass matrix. By using th

There are physical Majorana phases in the lepton flavor mixing matrix when neutrinos are Majorana fermions. In the case of two degenerate neutrinos, the physical Majorana phase plays the crucial role for the stability of the maximal flavor mixing bet

We study an energy-scale dependence of the lepton flavor-mixing matrix in the minimal supersymmetric standard model with the effective dimension-five operators, which give Majorana masses of neutrinos. We analyze the renormalization group equations o

We examine the $��_Q - ��'_Q$ mixing and heavy baryon masses in the heavy quark effective theory with the $\mq$ corrections. In the conventional baryon assignment, we obtain the mixing angle $\cos^2 ��= 0.87\pm 0.03$ in virtue of the Gell

We study the P-wave charmed meson spectroscopy. We analyze the mixing of two 1 +states, the masses and decay widths of the P-wave charmed mesons by use of the Breit·Fermi Hamiltonian to account for the 1/mQ effects. Though the possibility of the cas
