A recent paper [M. Kamata and T. Koikawa, Phys. Lett. B353 (1995) 196.] claimed to obtain the charged version of the (2 + 1)-dimensional spinning BTZ black hole solution by assuming a (anti-) self dual condition imposed on the electric and magnetic fields. We point out that the angular momentum and mass diverge at spatial infinity and as a consequence the solution is unphysical

We previously reported that in mesenteric arteries from streptozotocin (STZ)-induced diabetic rats that 1) endothelium-derived hyperpolarizing factor (EDHF)-type relaxation is impaired, possibly due to a reduced action of cAMP via increased phosphodiesterase 3 (PDE3) activity (Matsumoto T, Kobayashi T, and Kamata K. Am J Physiol Heart Circ Physiol 285: H283-H291, 2003) and that 2) PKA activity ...
Activation of the Hageman factor-kallikrein-kinin system by serratial 56-kDa proteinase was previously demonstrated (Matsumoto, K., Yamamoto, T., Kamata, T., and Maeda, H. (1984) J. Biochem. (Tokyo) 96, 739-749; Kamata, R., Yamamoto, T., Matsumoto, K., and Maeda, H. (1985) Infect. Immun. 48, 747-753). To investigate whether the activation of the system is specific for 56-kDa proteinase or is fo...
Invited for this month's cover picture are the groups of Prof. Takeo Yamaguchi and Keigo Kamata at Tokyo Institute Technology. The illustrates data-driven investigation trend in crystal structures iron-based oxides their electrocatalysis on oxygen evolution reaction (OER). using 24 kinds concluded that OER efficiency was uniquely determined by Fe–O bond length bulk crystals materials.

Embedding item response theory (IRT) models within a multilevel modeling framework has been shown by many authors to allow better estimation of the relationships between predictor variables and IRT latent traits (Adams, Wilson, & Wu, 1997). A multilevel IRT model recently proposed by Kamata (1998, 2001) yields the additional benefit of being able to accommodate data that are collected in hierar...
Jiro Hozawa, Shigeki Kamata, Takashi Ishida and Noriko Kimura (Hirosaki University) The labyrinths of guinea pigs sensitized by horseradish peroxidase (HRP) were investigated by electronmicroscopy after challenging this antigen through the foram. stylomastoideum. Horizontal nystagmus toward the contralateral side was observed about fifteen minutes after challenging. The animals sacrified in thi...
