Dynamics of Enceladus and Dione inside the 2:1 mean-motion resonance under tidal dissipation
In a previous work (Callegari and Yokoyama, Celest. Mech. Dyn. Astr. 98:5–30, 2007), the main features of the motion of the pair Enceladus–Dione were analyzed in the frozen regime, i.e., without considering th...

Epidermal growth factor receptor gene mutation, amplification and protein expression in malignant pleural mesothelioma
Epidermal growth factor receptor (EGFR) is overexpressed in a variety of epithelial malignancies. In lung cancer cases, EGFR gene mutation at the kinase domain and EGFR gene amplification are reported to be predi...

Autophagy-inducing agents augment the antitumor effect of telerase-selve oncolytic adenovirus OBP-405 on glioblastoma cells
Oncolytic adenoviruses are a promising tool in cancer therapy. In this study, we characterized the role of autophagy in oncolytic adenovirus-induced therapeutic effects. OBP-405, an oncolytic adenovirus regula...

Identification of the female-determining region of the W chromosome in Bombyx mori
The W chromosome of the silkworm Bombyx mori is devoid of functional genes, except for the putative female-determining gene (Fem). To localize Fem, we investigated the presence of W-specif...

Search for Nodulation Gene Inducer for Mesorhizobium loti Secreted from Roots of Lotus corniculatus
It has been established that an inducer secreted from roots of host leguminous plants is needed for the expression of the nod genes. Several types of compounds, e.g., flavonoids, betains and aldonic acids, have b...

Theory of Josephson Effect in Sr2RuO4/Diffusive Ferromagnet/Sr2RuO4 Junctions
We study Josephson effect in Sr2RuO4/insulator/diffusive ferromagnet (DF)/insulator/Sr2RuO4 junctions, solving the Usadel equation under a new boundary condition for DF/Sr2RuO4 interface. Josephson current is ca...

Dependence of Josephson Current on Orientational Angle in Diffusive p-Wave Superconductor Junctions
We calculate Josephson current in p-wave superconductor (P)/diffusive normal metal (DN)/insulator/diffusive normal metal/p-wave superconductor junctions, using quasi-classical Green’s function theory. We study t...

Dynamics of two satellites in the 2/1 Mean–Motion resonance: application to the case of Enceladus and Dione
The dynamics of a pair of satellites similar to Enceladus–Dione is investigated with a two-degrees-of-freedom model written in the domain of the planar general three-body problem. Using surfaces of section and...
