We examine the influence of Ni impurity in cuprates on the distribution of hole carriers by performing numerically exact diagonalization calculations for a model consisting of Cu 3d, Ni 3d, and O 2p orbitals. Using realistic parameters for the system, we find that a hole is predominantly bound to O 2p orbitals around the Ni impurity forming the Zhang-Rice doublet. This imposes strong restrictions on modeling Ni-substituted cuprates. We propose a resonant inelastic x-ray scattering experiment for Ni K edge to confirm hole binding around the Ni impurity.

In this paper, the authors propose an improved identification method of the magnetizing inrush current phenomena. To improve the estimation of the saturation on/off time, the Aitken's Δ 2 -process is adopted. And a new index δI, which is a variation current, is introduced. The merits of Aitken's Δ 2 -process are the simple algorithm and the high precision to oscillation noise. Then, the proposed method is adapted to a measured data, in which the oscillation noise is caused. The proposed method gives a high precision in these cases.

Malignant lymphoma of the uterine cervix is exceedingly rare and is difficult to diagnose by cervical cytology. The current study presents a case of malignant lymphoma of the uterine cervix that was presumptively diagnosed by cervical cancer screening in which the patient had no clinical symptoms. The anterior lip of the uterine cervix was occupied by a macroscopic hemorrhagic tumor. The obtained tumor cells exhibited typical cytological features of malignant lymphoma and were positive for CD20. The final diagnosis was diffuse large B cell lymphoma of the uterine cervix, stage IIEA (Ann Arbor classification). The patient received 6 courses of R-CHOP chemotherapy and achieved complete remission. Despite its rarity, the possibility of malignant lymphoma should be considered while screening for cervical cancers using Pap smears. The Pap test screening may be useful for the early diagnosis of malignant lymphoma of the uterine cervix in certain cases. By reaching a rapid and accurate diagnosis, immediate treatment may be initiated and surgery may be avoided.
