Recently, nuclear structure in neutron-rich nuclei has attracted much attention because of its exotic nature, such as halo and skin 1) 3). Recent advances of secondary beam techniques allow us to measure useful structure information on masses, interaction cross sections and excited states. The shell structure is one of essential issues in nuclear structure. Recently, the magic numbers in the ne...

To study the mechanism of granule centralization in platelets, we permeabilized with saponin in either EGTA (5 mM) or calcium (1 or 10 microM). Under all conditions, platelets retained 40-50% of their total actin and greater than 70% of their actin-binding protein (ABP) but lost greater than 80% of talin and myosin to the supernatant. Thin sections of platelets permeabilized in EGTA showed a mi...

We present ground state photoionization cross sections of atoms and ions averaged over resonance structures for photoionization modeling of astrophysical sources. The detailed cross sections calculated in the closecoupling approximation using the R-matrix method, with resonances delineated at thousands of energies, are taken from the Opacity Project database TOPbase and the Iron Project, includ...

Single-photon double K-shell ionization of low-Z neutral atoms in the range 12 Z 23 is investigated. The experimental method was based on measurements of the high-resolution Kα hypersatellite x-ray spectra following the radiative decay of the K-shell double-vacancy states excited by monochromatic synchrotron radiation. The photon energy dependence of the double K-shell ionization was measured o...

The optical properties of a concentric nanometer-sized spherical shell comprised of an (active) 3-level gain medium core and a surrounding plasmonic metal shell are investigated. Current research in optical metamaterials has demonstrated that including lossless plasmonic materials to achieve a negative permittivity in a nano-sized coated spherical particle can lead to novel optical properties s...
