    Notes: We have developed the highly efficient neutron detector system MANDALA for the inertial-confinement-fusion experiment. The MANDALA system consists of 842 elements plastic scintillation detectors and data acquisition electronics. The detection level is the yield of 1.2×105 for 2.5 MeV and 1×105 for 14.1 MeV neutrons (with 100 detected hits). We have calibrated the intrinsic detection efficiencies of the detector elements using a neutron generator facility. Timing calibration and integrity test of the system were also carried out with a 60Co γ ray source. MANDALA system was applied to the implosion experiments at the GEKKO XII laser facility. The integrity test was carried out by implosion experiments. © 1999 American Institute of Physics.

    Mesozoic tectonothermal development of the Sambagawa, Mikabu and Chichibu belts, south-west Japan: evidence from 40Ar/39Ar whole-rock phyllite ages (1995)

    Notes: Abstract Five whole-rock 40Ar/39Ar plateau ages from low-grade sectors of the Sambagawa belt (Besshi nappe complex) range between 87 and 97 Ma. Two whole-rock phyllite samples from the Mikabu greenstone belt record well-defined 40Ar/39Ar plateau ages of 96 and 98 Ma. Together these ages suggest that a high-pressure metamorphism occurred in both the Sambagawa and Mikabu belts at c. 90–100 Ma. The northern Chichibu sub-belt may consist of several distinct geochronological units because metamorphic ages increase systematically from north (c. 110 Ma) to south (c. 215 Ma). The northern Chichibu sub-belt is correlated with the Kuma nappe complex (Sambagawa belt). Two whole-rock phyllite samples from the Kurosegawa terrane display markedly older metamorphic ages than either the Sambagawa or the Chichibu belts.Accretion of Sambagawa-Chichibu protoliths began prior to the middle Jurrasic. Depositional ages decrease from middle Jurassic (Kuma-Chichibu nappe complex) to c. 100 Ma (Oboke nappe complex) toward lower tectonostratigraphic units. The ages of metamorphic culmination also decrease from upper to lower tectonostratigraphic units. The Kurosegawa belt and the geological units to the south belong to distinctly different terrances than the Sambagawa-Chichibu belts. These have been juxtaposed as a result of transcurrent faulting during the Cretaceous.

    Numerical Liouville approach: Formulation of third-order nonlinear optical susceptibilities (1995)

    Notes: As a continuation of a previous paper [Phys. Rev. A 50, 2989 (1994)], this article develops and describes in detail the new nonperturbative approach to the third-order nonlinear optical susceptibilities χ(3)g(ω) in third-harmonic generation (THG), electric-field-induced second-harmonic generation (EFISH), degenerate four-wave mixing (DFWM), electric-field-induced optical rectification (EFIOR), and electric-field-induced Kerr effect (EFIKE) for N-state quantum systems interacting with intense electric fields. The present method utilizes the Fourier transformation of numerically exact solutions of the Liouville equation, so that it can provide both real and imaginary nonlinear optical spectra valid for arbitrary laser intensities, frequencies, and relaxation. As an application of the method, we investigate the characteristics of nonlinear optical spectra in THG, EFISH, and DFWM for a three-state model that mimics the electronic excited states of t-octatetraene obtained from a full configuration interaction (FCI) calculation using the Pariser–Parr–Pople (PPP) Hamiltonian. Comparisons between the present nonperturbative and the conventional perturbative results are also carried out. The magnitudes of the third-order nonlinear susceptibilities in the off-resonant region show the following trend: χ(3)(THG)(approximately-greater-than)χ(3)(EFISH)(approximately-greater-than)χ(3)(DFWM), with χ(3)(THG) exhibiting the largest frequency dispersion. © 1995 American Institute of Physics.

    Numerical Liouville approach: Three-type analysis of virtual excitation processes of third-order nonlinear optical spectra in third-harmonic generation (1995)

    Notes: An analysis method based on virtual excitation processes is developed in numerical Liouville approach, which is a new nonperturbative method presented before. In this analysis method (NLA three-type analysis method), third-order nonlinear optical susceptibilities χ(3)g(ω) obtained by the NLA method can be divided into the three-type virtual excitation processes similar to the three-type analysis based on the time-dependent perturbation theory (TDPT three-type analysis). The NLA three-type analysis method is superior to the TDPT three-type analysis one in the points as follows: (1) the NLA three-type analysis can treat the phenomena caused by the intensity-dependent nonlinear susceptibilities including nonperturbative effects and (2) the NLA three-type analysis can divide the resonant nonlinear susceptibilities into three types of virtual excitation processes. In order to explain the procedure of the present analysis, we try to elucidate the characteristics of virtual excitation processes of nonlinear optical spectra in THG for a three-state model that mimics the electronic excited states of a system with noncentrosymmetric charge distribution. © 1995 American Institute of Physics.

    Spontaneous hybridization in the laboratory and genetic markers for the identification of hybrids between two atherinid species, Odontesthes bonariensis (Valenciennes, 1835) and Patagonina hatcheri (Eigenmann, 1909) (1997)

    Notes: This study reports the occurrence of spontaneous hybridization between Odontesthes bonariensis (Valenciennes, 1835) and Patagonina hatcheri (Eigenmann, 1909), two South American freshwater atherinids, while adults of both species were being held in a communal laboratory tank, and describes suitable genetic markers for distinction of both species and their hybrids. Combined allozyme and mitochondrial DNA restriction length polymorphism analyses of offspring from three spawnings in the communal tanks confirmed the presence of hybrids along with purebreds in each spawning. Hybrids of an O. bonariensis mother X a P. hatcheri father were produced along purebred O. bonariensis in one occasion, whereas hybrids of P. hatcheri mothers X O. bonariensis fathers were produced along purebred P. hatcheri in two occasions. Three enzyme systems (coded by loci LDH-B*, PGM*, and CK*) out of 15 (20 loci) screened allowed distinction of species and their hybrids, but the usefulness of LDH-B* for field work may be limited by intraspecific polymorphism. Eight restriction enzymes (Apa I, Bgl II, Eco RI, Eco RV, Eco T22I, Hinc II, Hind III, and Pvu II) among 11 produced diagnostic restriction fragments applicable for species (motherhood) distinction. The relevance of these findings for the management of natural genetic resources and the aquaculture of these two species is discussed.

    Cloning and characterization of pejerrey mitochondrial DNA and its application for RFLP analysis (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 51 (1997), S. 0

    Topics: Biology
    Notes: Probes were cloned, characterized, and developed for all regions of the mitochondrial DNA (mtDNA) of pejerrey Odontesthes bonariensis to provide the basis for the study of genetic diversity of South American atherinopsinii and to enable species identification from small amounts of tissue. The mtDNA was extracted from liver and cleaved with Eco RI, producing four fragments (7.4, 3.4, 3.1 and 2.9 kb) which were cloned using pUC118 plasmid vectors. Sequence analysis from both ends of the fragments showed that they encode tRNA (Asp, Phe, and Ser-TGA), 12 S rRNA, cytochrome oxidase (CO) II, NADH 4, 5, and 6, and the D-loop, and that the relative positions of these genes are identical to those in the mtDNA of other teleosts. A comparison of homology with carp mtDNA nucleotide sequences revealed that tRNA (Phe and Ser-TGA) and CO II were relatively conserved, whereas the D-loop region was highly divergent. The cloned mtDNA probes detected mtDNA fragments from about 800 ng of total DNA extracted from liver, muscle, and single embryos of O. bonariensis, and were effective for restriction length fragment polymorphism (RFLP) analysis of Patagonina hatcheri, the most distant atherinopsine relative of pejerrey. The cloned mtDNA probes may be useful for the analysis of genetic diversity and non-destructive species identification, including the examination of eggs, larvae and juveniles. The mtDNA sequences reported here provide the basis for the design of primers for PCR-based RFLP analysis.
