Kawahara and collaborators analyzed the transits of the candidate disintegrating Mercury-mass planet KIC 12557548b and suggested that the transit depths were correlated with the phase of the stellar rotation. We have carried out a more extensive and comprehensive analysis of the transit depths of KIC 12557548b and confirm that there is indeed a robust, statistically significant signal in the tr...

Hashimoto, Chikara and Kawahara, Daisuke. 2008. Drawing a Line between Literal and Idiomatic Meanings Based on Supervised WSD. Linguistic Research 25(2), 105-123. Some phrases can be interpreted either idiomatically (figuratively) or literally in context, and the precise identification of idioms is indispensable for full-fledged natural language processing (NLP). To this end, we have constructe...

GluR2 is a subunit of the AMPA receptor, and the adenosine for the Q/R site of its pre-mRNA is converted to inosine (A-to-I conversion) by the enzyme called adenosine deaminase acting on RNA 2 (ADAR2). Failure of A-to-I conversion at this site affects multiple AMPA receptor properties, including the Ca(2+) permeability of the receptor-coupled ion channel, thereby inducing fatal epilepsy in mice...

We report the presence in the rat pituitary of a calcium-activated, phospholipid-dependent protein kinase (C kinase), originally described by Takai et al. [Takai, Y., Kishimoto, A., Iwasa, Y., Kawahara, Y., Mori, T. & Nishizuka, Y. (1979) J. Biol. Chem. 254, 3692-3695]. Enzyme activity is absolutely dependent on the simultaneous presence of Ca2+ and phospholipid--in particular, phosphatidylseri...

We analyze coherent structures in nonlocal dispersive active-dissipative nonlinear systems, using as a prototype the Kuramoto–Sivashinsky (KS) equation with an additional nonlocal term that contains stabilizing/destabilizing and dispersive parts. As for the local generalized Kuramoto–Sivashinsky (gKS) equation (see, e.g., [T. Kawahara and S. Toh, Phys. Fluids, 31 (1988), pp. 2103–2111]), we sho...

The subcellular distribution of Ca2+-activated, phospholipid-dependent protein kinase (Takai, Y., Kishimoto, A., Iwasa, Y., Kawahara, Y., Mori, T., and Nishia k a , Y. (1979) J. Biol. Chem 254, 3692-3695) in rat brain was investigated. Approximately one-third of the protein kinase was recovered in the soluble cytosol fraction, another one-third was in the crude mitochondrial fraction, and the r...

A total of 53 strains of onion thrips, Thrips tabaci Lindeman, were established, of which 14 strains were collected from persimmon fruit and 39 strains from a vetch weed, Vicia angustifolia, in commercial persimmon orchards in Wakayama Prefecture. Susceptibility to insecticides was evaluated by the Petri dish-spraying tower method. Pyrethroid-resistant strains and pyrethroid-susceptible strains...

A report is made on a case of liposarcoma of stomach in a 42 year old man. This is the first case of liposarcoma of stomach reported in Japan. The patient has remained asymptomatic for five years after operation. ∗PMID: 4239074 [PubMed indexed for MEDLINE] Copyright c ©OKAYAMA UNIVERSITY MEDICAL SCHOOL Acta Med.
