We report studies of the electronic structure and elementary excitations of undoped, one- and two-dimensional cuprates. Using high-energy spectroscopies such as X-ray absorption, photoemission and electron energy-loss spectroscopy, important informat

The optical conductivity spectrum of Sr{sub 14-x}Ca{sub x}Cu{sub 24}O{sub 41}, composed of two-leg Cu{sub 2}O{sub 3} ladders and edge-sharing CuO{sub 2} chains, is investigated on single crystals with various compositions. Upon isovalent Ca substitut

The fate of chloroplast nuclei (cp-nuclei) was followed in young zygotes after mating of male and female gametes in Chlamydomonas reinhardtii using two methods; i.e., observation of a single field by both epifluorescent and electron microscope, and o

In this paper, we investigate a predictive density distribution of millimeter-wave (MMW) backscattering from terrain for the purpose of the estimation of MMW clutter distribution. In order to derive the density, the product model represented by speck
