Times Cited Count：8 Percentile：69.3(Multidisciplinary Sciences)Quantum transport is ubiquitous in physics. So far, quantum transport between terminals has been extensively studied in solid state systems from the fundamental point of views such as the quantized conductance to the applications to quantum devices. Recent works have demonstrated a cold-atom analog of a mesoscopic conductor by engineering a narrow conducting channel with optical potentials, which opens the door for a wealth of research of atomtronics emulating mesoscopic electronic devices and beyond. Here we realize an alternative scheme of the quantum transport experiment with ytterbium atoms in a two-orbital optical lattice system. Our system consists of a multi-component Fermi gas and a localized impurity, where the current can be created in the spin space by introducing the spin-dependent interaction with the impurity. We demonstrate a rich variety of localized-impurity-induced quantum transports, which paves the way for atomtronics exploiting spin degrees of freedom.

The temperature and energy of electrons are important issues when energy and particle fluxes to the divertor are evaluated. To do this, we have analyzed the electron energy distribution function by differentiating the probe current with respect to the probe voltage numerically, where probe current has been measured in the divertor plasma of JT-60U. We have evaluated the electron temperature and the shape of the distribution function when the X point MARFE and the plasma detachment are formed.

CYP2C9 belongs to cytochrome P450 and play an important role as human drug metabolizing enzyme. In this study, to elucidate molecular mechanism in drug metabolizing reaction by wild-type CYP2C9 and its SNP mutant *30, X-ray structures of their CYP2C9 molecules complexed with the drug were determined. CYP2C9 was truncated at N-terminal, expressed in E. coli, and homogeneously purified for crystallization. CYP2C9 Losartan complex was crystallized by co-crystallization. As a result of experiments using synchrotron radiation, diffraction data were obtained at 2.1
resolution. The electron density maps of bound Losartan were observed in the both complexes.
