    Notes: Abstract Phylogenetic relationships among the seven species of deep-sea giant clams Calyptogena (Bivalvia: Vesicomyidae) collected around Japan were examined using parts of nucleotide sequences of mitochondrial genes for cytochrome oxidase I (COI) and cytochrome oxidase III (COIII) and the encoded amino acid sequences. The seven species were C. soyoae (Sagami Bay), C. fausta (Suruga Bay), C. kaikoi (Nankai Trough), C. nautilei (Nankai Trough), C. phaseoliformis (Japan Trench), C. solidissima (Minami-Ensei Knoll, Okinawa Trough) and Calyptogena sp. (Iheya Ridge, Okinawa Trough). A clear phylogenetic split was observed between one group of three species (C. kaikoi, C. phaseoliformis and C. fausta) and the remaining species. This clustering corresponds to the two previously described subgenera within the genus Calyptogena (Calyptogean and Ectenagena) with the exception of the placement of C. nautilei, which had been placed in the subgenus Ectenagena. Genetic distances between two haplotypes of C. soyoae were 0.043 for the COI region and 0.055 for the COIII region, and three amino acid substitutions were detected with the COIII region. Calyptogena sp. from the Iheya Ridge could be distinguished from one of the two haplotypes (type A) of C. soyoae by only a single nucleotide substitution, a result that suggests that Calyptogena sp. of the Iheya Ridge diverged from C. soyoae after the two haplotypes had diverged, and it is now isolated from C. soyoae in Sagami Bay.

    Notes: Abstract The pilchards (genus Sardinops), one of the major components of the world's harvest of fishes, is distributed sporadically in the temperate zone on a global scale. Mitochondrial DNA variation in 95 pilchards from nine worldwide localities in five current systems was examined using ten restriction enzymes. Although several opinions have been proposed on the global population structure of the genus Sardinops, our results clearly rejected the hypothesis of gene flow among geographically distant populations on a global scale. Results indicate that the Japanese pilchards and the Australian and South African pilchards were derived from the eastern Pacific populations, following the speciation of Sardinops in the Pacific, after the formation of the Isthmus of Panama. An intermixing of the northeastern and southeastern Pacific populations during the Pleistocene glacial maxima is suggested from their genetic affinities.

    Notes: Abstract. In this study, the pulsed laser ablation of RuO2 and SrRuO3 (SRO) is investigated by observing the fluorescence from excited atoms in the plume by using a framing streak camera. Vaporization, phase explosion and boiling are suggested to play the main roles in the processes for the interaction between the laser beam and target. Collisions and adiabatic expansion are also suggested before particles move forward with shifted Maxwellian spatial distribution. In O2 pressure, numerous collisions between fast and slow atoms occur and result in the exchange of speeds. The structural and electrical (conductivity and work-function) properties of RuO2 and SRO thin films are measured. Epitaxial SRO growth was obtained at growth temperatures down to 350 °C. Ferroelectric and high- dielectric thin-film capacitors with RuO2 or SRO thin film electrode are also studied.

    Notes: An alkaline serine protease, M-protease, from Bacillus sp. KSM-K16 has been crystallized. Two morphologically different crystal forms were obtained. Crystal data of form 1: space group P212121, a = 47.3, b = 62.5, c = 75.6 Å, V = 2.23 × 105 Å3, Z = 4 and Vm = 2.09 Å3 Da−1. Crystal data of form 2: space group P212121, a = 75.82 (2), b = 57.79 (2), c = 54.19 (1) Å, V = 2.29 (2) × 105 Å3, Z = 4 and Vm = 2.15 Å3 Da−1. The crystal structure of M-protease in form 2 has been solved by molecular replacement using the atomic model of subtilisin Carlsberg (SBC) which is 60% homologous with M-protease, and refined to the crystallographic R-factor of 0.189 for 7004 reflections with Fo/σ(F) 〉 3 between 7 and 2.4 Å resolution. The final model of M-protease contains 1882 protein atoms, two calcium ions and 44 water molecules. The three-dimensional structure of M-protease is essentially similar to other subtilisins of known structure. The 269 Cα positions of M-protease have an r.m.s. difference of 1.06 Å with the corresponding positions of SBC. The crystal data of form 2 are close to those of SBC, though the structure determination of form 2 made it clear that it is not isomorphous to the crystal structure of SBC. The deletions of amino acids occur at the residues 36′ and 160′–163′ compared with SBC (numerals with primes show the numbering for SBC). The deletion of the four residues (160′–163′) may significantly affect the lack of isomorphism between M-protease and SBC.

    Notes: Two sympatric morphs (type A with a vertebral number of 25 and type B with a vertebral number of 24) of striped jack Pseudocaranx dentex (Bloch & Schneider) were analysed genetically. A part of the 16S–rRNA region of mtDNA was amplified with polymerase chain reaction for 24 specimens, and a restriction enzyme fragment polymorphism showed significant differences between the two types. While all specimens sampled in Ogasawara were identified as type B, about 90% of striped jack in Oita were type A and 10% were type B. Although the spawning areas of these two types are still unknown, significant genetic differences between the two sympatric morphs show that recruitment and migration patterns might differ from each other. The current system suggests the possibility that the juveniles of type B in Oita may migrate from the Ogasawara Islands.

    Notes: Adhesion between thin Te-based alloy films and fluorocarbon polymer sublayers, prepared by sputtering or plasma polymerization, was investigated by observing the 1 μm-sized ablative hole opening process with a focused laser beam. Interpretations of the mechanisms for the change in energy required for the hole opening and pit geometry were based on the framework of studies of the ablative hole opening process for optical recording. Observations suggest that the molten material flow during the hole opening includes a ductile fracture and a viscous flow of the molten sublayer material as well as of active layer material. Adhesion acts as an energy barrier against the above mentioned flow of molten material during the hole opening process. Since the fluorocarbon films used in the present work had highly cross-linked structures, the adhesion was mainly dominated by the dynamic force of adhesion. Therefore, the hole opening process was mainly affected by the dynamic force of adhesion rather than the static force, which is dominated by the surface energy of the sublayer. There was a good correlation between the dynamic force of adhesion estimated by the peel-off strength and the concentrations of the -CF- and -C-CF- structures estimated from C1s spectra obtained by x-ray photoelectron spectroscopy. © 1995 American Institute of Physics.
