Dynamic evolution of a small-scale structure to a large-scale structure is studied by a nonlinear dissipative LC ladder circuit. The circuit is described by a Burgers equation in the lowest order. We confirmed that the observed propagation of a shock wave and the confluence of shock waves are well described by the theory. A single hump wave is used to model a small-scale structure. When two single-hump waves with different amplitudes are applied to the circuit, they evolve into a large-scale structure in the course of propagation. Such a formation of a large-scale structure is unique in a nonlinear dissipative system, while the nonlinear dispersive system is known to preserve the nature of small-scale structures even after their interaction as known for solitons.

Scrape cytology of pemphigus vulgaris of the nipple, a mimicker of Paget's disease

Diagnostic Cytopathology (1997)

Tadao K. Kobayashi Masami Ueda Toshihiro Nishino Sachiko Kibe Takashi Higashida

A case of histologically and immunocytochemically confirmed pemphigus vulgaris of the nipple examined by scrape cytology is reported. The scrape cytology showed isolated and somewhat loosely clustered cells with basophilic cytoplasm and vesicular hyperchromatic nuclei dysplaying prominent nucleoli, suggesting Paget's disease of the nipple. However, histological examination of the resected tissue together with the direct immunofluorescence technique for demonstration of in vivo-bound immunoglobulin to epithelium confirmed the diagnosis of pemphigus vulgaris. The use of an immunoperoxidase stain for IgG on the Papaniolaou-destained smear also gave a positive reaction on the cell membranes and provided a precise cellular diagnosis of the lesions. Cytodiagnostic pitfalls of these rare breast lesions are discussed, as well as the diagnostic value of immunocytochemistry. Diagn. Cytopathol. 16:156–159, 1997. © 1997 Wiley-Liss, Inc.

Ion-acoustic solitons excited by a single grip

Journal of Plasma Physics (1975)

Shinsuke Watanabe

Ion-acoustic solitons are observed to form when a large-amplitude positive step voltage is applied to a single mesh grid. For the formation of the soliton, the sheath about the grid plays an important rôle. The number and the amplitude of the solitons are examined experimentally as a function of the nonlinear index, and are compared with theory. The observed width and the velocity of the soliton are well explained by the theory of a hot-ion fluid and Boltzmann electrons. The phase delay of two solitons by a head-on collision is also observed.

Malignant pleural effusions due to adeno-endocrine-cell carcinoma of the appendix: A case report

Diagnostic Cytopathology (1997)

Tadao K. Kobayashi Masami Ueda Toshihiro Nishino Toshiyuki Tamagaki Shinsuke Watanabe

The cellular features of adeno-endocrine-cell carcinoma of appendiceal origin are presented. The pleural fluid contained metastatic predominantly atypical cells in linear cluster accompanied by numerous mesothelial cells. The cells had small round nuclei, with a slight tendency to molding; nucleoli were absent. The cytologic findings in Papanicolaou-stained smears of the pleural fluid suggested a metastatic small-cell carcinoma of the lung. Subsequently, adeno-endocrine-cell carcinoma of the appendix was demonstrated at autopsy. Reports of such occurrences are few; no study, to the best of our knowledge, has previously documented the cytologic diagnosis in pleural fluid. Diagn.
