    Notes: The coercive forces and anisotropy fields of Fe-Ru-Ga-Si films deposited on 30° tilted substrates were measured for varying chemical compositions and crystal orientations. The minimum coercivity and minimum in-plane magnetic anisotropy were observed at an iron-rich composition corresponding to a substantial magnitude of anisotropy constant: K1=6×103 (J/m3). From an orientation analysis of the crystal aggregate, this optimization with the large K1 was understood to be a result of the cancellation of the shape anisotropy by the crystalline anisotropy.

    Spin-polarized secondary electron microscopy of soft magnetic films on antiferromagnetic substrates : The 41st annual conference on magnetism and magnetic materials (1997)

    Notes: Coupling of soft magnetic films to antiferromagnetic substrates was studied by spin-polarized secondary electron microscopy. Permalloy (Ni80Fe20 alloy) films were deposited on antiferromagnetic NiO(111) single-crystal substrates. A domain structure consisting of fine grains (∼50 μm) was characteristic of the NiFe film deposited without applying magnetic field. The domain image and its response to applied field suggested existance of local easy axis and local unidirectional anisotropy. When macroscopic unidirectional anisotropy was introduced to the NiFe film by depositing under an applied dc magnetic field, many of the fine grains disappeared and the film showed large domains (∼1 mm). In the large domains, small elongated reversed domains (∼20 μm×60 μm) aligned parallel to each other implying local easy axis of magnetization. The type of domain behavior described above was not observed in a NiFe film on MgO(111) substrate that had the same crystal structure as NiO but no magnetic ordering. An x-ray analysis revealed that the local easy axes observed in NiFe/NiO specimens coincided with the [112¯] of the NiO crystal lying in the (111) substrate plane, which supported coupling of the NiFe film with the single-crystal substrate. © 1997 American Institute of Physics.

    Fabricating nanoscale magnetic mounds using a scanning probe microscope : The 40th annual conference on magnetism and magnetic materials (1996)

    Notes: Nanometer-scale mounds were fabricated by applying voltage pulses between a substrate and an atomic force microscope cantilever coated with magnetic material. Mounds were formed on both insulator and conducting substrates. Magnetic force microscopy (MFM) observations of the fabricated mounds were performed, and the contrast was turned over by reversing the magnetization of the tip, which is convincing proof that the mounds are magnetic. The MFM images also suggest that the mounds are perpendicularly magnetized. These results demonstrate that scanning probe microscope based nanofabrication is a promising method to fabricate nanoscale magnetic dots on any kind of substrates. © 1996 American Institute of Physics.

    Productin of Basic Fetoprotein in Human Peripheral Lymphocytes during Blastic Transformation (1992)

    Notes: To clarify the significance of basic fetoprotein (BFP) in lymphocytes, we investigated whether BFP is produced in lymphocytes during blastic transformation. Peripheral blood lymphocytes obtained from 14 adults were cultured under the stimulation of lectins. The concentration of BFP in the culture medium (extracellular BFP) was estimated serially. The incorporation of [6-3 H] thymidine was assayed simultaneously. The intracellular BFP was measured by dual flow cytometry for DNA and BFP. A lymph node was studies immunohistochemically. Serum BFP was measured in four cases of lumphocytic leukaemia. In two cases, dual staining was performed. The intracellular BFP of the mitogen-stimulated lymphocytes was increased within 24 h. The extracellular BFP was increased exponentially from 72 h. The extracellular BFP at 96 h did not correlate with the [3H]-thymidine incorporation. The intracellular BFP increase began in G1 phase. Immunostaining showed that the B cells also produced BFP. Theserum BFP level in leukaemia was high in 1 of 4 cases and the leukaemic cells in two cases showed high intracellular BFP content. These observations indicate that BFP is produced in activated human lymphocytes and in lymphocytic leukaemic cells. The production of BFP during blastic transformation will be a useful new in vitro model for studying the biological role of BFP, and BFP labelling may offer some new possibilities for study of lymphocytes.

    General theory of coincidence-site lattices, reduced 0-lattices and complete pattern-shift lattices in arbitrary crystals (1976)

    Notes: The definition of a lattice and its superlattice is given algebraically. A coincidence site lattice (CSL) is defined as an intersection lattice of any two crystal lattices, and a complete pattern-shift lattice (DSCL) as the set theoretically smallest lattice containing both crystal lattices as superlattices. In the case where the two lattices are related by a non-singular matrix (having non-zero determinant), the so-called 0-lattice may be generated from the two crystal lattices. Any translation of the 0-lattice by all the vectors of one of the crystal lattices forms a lattice, i.e. a reduced 0-lattice. As a result of the theory of groups and numbers, the reduced 0-lattice (abbreviated to ROL) is homomorphic to the DSCL. It is shown that the factor group of all cosets of lattice 1 in the DSCL (in the ROL) is isomorphic with the factor group of all cosets of the CSL in lattice 2 (in the 0-lattice). The volume of a unit cell is derived for all the lattices generated by the two crystal lattices. Secondly, the reciprocal of a lattice is introduced and the reciprocity between the CSL and the DSCL determined by the reciprocals of the two crystal lattices is shown as a special case of a theorem mentioned about modules over a ring. Finally a complete diagram of relationships between b-lattices and 0-lattices for direct lattices and reciprocal lattices is given.

    Notes: In cubic polycrystals, combinations of coincidence orientation relationships at a triple junction of grains A, B and C can be obtained by using the equation ΣCA = ΣABΣBC/d2, where d is a common divisor of ΣAB and ΣBC. This paper describes the derivation of this equation and shows several models of polycrystals composed of specially selected coincidence boundaries using the above equation.

    Notes: Abstract We present a case of Dandy-Walker malformation associated with occipital meningocele, microphthalmia, and cleft palate. Small numbers of cases of Dandy-Walker malformation with occipital meningocele have been described in the literature, but to our knowledge, non of these also had microphthalmia or cleft palate. This association suggests that time of intrauterine origin of Dandy-Walker syndrome was in the sixth or seventh embryonic week. In the diagnosis, both CT cisternography and direct neurosonography over the occipital meningocele was useful for the demonstration of a posterior fossa cyst which communicated with the fourth ventricle and the occipital meningocele.

    Studies on interdomain interaction of 3-isopropylmalate dehydrogenase from an extreme thermophile, Thermus thermophilus, by constructing chimeric enzymes (1999)

    Notes: Abstract In our previous study, we showed that a chimeric isopropylmalate dehydrogenase, 2T2M6T, between an extreme thermophile, Thermus thermophilus, and a mesophile, Bacillus subtilis, isopropylmalate dehydrogenases (the name roughly denotes the primary structure; the first 20% from the N-terminal is coded by the thermophile leuB gene, next 20% by mesophile, and the rest by the thermophile gene) denatured in two steps with a stable intermediate, suggesting that in the chimera some of the interdomain interaction was lost by amino acid substitutions in the "2M" part. To identify the residues involved in the interdomain interactions, the first and the second halves of the 2M part of the chimera were substituted with the corresponding sequence of the thermophile enzyme. Both chimeras, 3T1M6T and 2T1M7T, apparently showed one transition in the thermal denaturation without any stable intermediate state, suggesting that the cooperativity of the conformational stability was at least partly restored by the substitutions. The present study also suggested involvement of one or more basic residues in the unusual stability of the thermophile enzyme.
