We suggest an entanglement purification scheme for mixed entangled coherent states using 50-50 beam splitters and photodetectors. This scheme is directly applicable for mixed entangled coherent states of the Werner type, and can be useful for general mixed states using additional nonlinear interactions. We apply our scheme to entangled coherent states(More)
Histidine decarboxylase (HDC) catalyzes the formation of histamine from histidine. Histamine has various effects in physiological and pathological reactions, such as inflammation, cell growth, and neuro-transmission. We investigated the role of hypoxia-inducible factor (HIF)-1 on hypoxia-induced HDC expression in human mast cell line, HMC-1 cells and mouse(More)
The emerging ISO/IEC 15504 standard provides a framework and a model for software process assessment and improvement. There are two requirements for reliable process assessment; internal reliability and external reliability. The objective of this study is to provide an empirical case of external re1iabiliQ i.e. the interrater agreement in ISO/IEC(More)
The theory of quantum computation promises to revolutionize the future of computer technology with merits such as factoring large integers [1] and combinational searches [2]. In recent years, the physical implementation of a quantum computer has been intensively studied. Quantum computing in optical systems has been studied as one of several plausible(More)
The paradox suggested by Einstein, Podolsky and Rosen aroused controversy about nonlocality of quantum states [1]. Bell proposed a remarkable inequality imposed by a local hidden variable theory [2], which enables a quantitative test on quantum nonlocality. Numerous theoretical studies and experimental demonstrations have been performed to understand(More)
To investigate the characteristics of interstitial inflammatory cells and possible involvement of nudelta T cells, 16 renal allograft biopsies showing chronic rejection were stained by immunohistochemical method and correlated with the data of peripheral blood evaluated by flow cytometry. For immunophenotyping, fresh frozen sections were stained with(More)

We report a case of glomerular disease with both mesangial IgA and subepithelial IgG deposits in the allograft kidney. The patient was a 36 year-old man who had received a renal allograft 1 year previously. Fifteen days before admission, he discovered a microscopic hematuria without clinical evidences of allograft rejection. Light microscopy showed diffuse(More)
The purpose of Blind Source Separation (BSS) is to obtain separated sources from convolutive mixture inputs. Among the various available BSS methods, Independent Component Analysis (ICA) is one of the representative methods. Its key idea is to repetitively update and calculate the measures. However, dealing with the measures obtained from multi-array(More)
Considering a multi-pathway structure in a light-harvesting complex of photosynthesis, we investigate the role of energy-level mismatches between antenna molecules in transferring the absorbed energy to a reaction center. We find a condition in which the antenna molecules faithfully play their roles: Their effective absorption ratios are larger than those(More)
