    Notes: Magnetization measurements for the compound SmCo3B2 have been performed on loose powder in magnetic fields to 5 T and in the temperature region from 4.2 to 60 K. A small saturation moment of 0.18 μB/SmCo3B2 at T=4.2 K and its variation with increasing temperature suggest ferrimagnetic ordering in SmCo3B2, which is explained as the effect of a higher order crystalline field coefficient. A magnetic first order transition occurs at T=43 K and metamagnetism occurs in the narrow temperature region between 43 and 47 K, for which some possible discussions are given. © 2000 American Institute of Physics.

    Simulation of the write field for T-shaped pole heads (2000)

    Notes: The write field distributions of T-shaped pole heads are presented. The maximum head field in the medium plane for T-shaped heads was larger than that for conventional structure heads. However, the field from the edges of the upper pole is not negligible for the T-shaped heads. As a result, neighboring bit patterns may be affected. To decrease the edge field, it is effective to make the throat height longer and recess the edges of the upper pole from the air bearing surface. Actual T-shaped heads were fabricated and their characterizations were investigated. The results agreed with simulations for longer throat height and for the recessed pole edge effect. © 2000 American Institute of Physics.

    Growth mode and surface morphology of a GaN film deposited along the N-face polar direction on c-plane sapphire substrate (2000)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 88 (2000), S. 1158-1165

    Notes: The dependence of polar direction of GaN film on growth conditions has been investigated by changing either the group-V/group-III ratio (V/III ratio) in supplying the source gas or the deposition rate. GaN films were deposited on a nitrided sapphire by two-step metalorganic chemical vapor deposition. The surface morphology changed from flat hexagonal to pyramidal hexagonal facet with the increase of V/III ratio. However, the polar direction of GaN on an optimized buffer layer of 20 nm thickness was N-face (−c) polarity, independent of both the V/III ratio and the deposition rate. The polarity of the GaN epitaxtial layer can be determined by that of an interface (nitrided sapphire, annealed buffer layer or GaN substrate) at the deposition of GaN epitaxial layer. The higher V/III ratio enhanced the nucleation density, and reduced the size of hexagonal facets. The nuclei, forming the favorable hexagonal facets of wurtzite GaN, should grow laterally along the {101¯0} directions to cover a room among the facets until coalescence. After coalescence, −c GaN growth on a flat hexagonal facet results in a pyramidal hexagonal facet. The growth mode for −c GaN has been discussed with respect to surface structure and migration length of adsorbing precursors, in comparison with Ga-face (+c) GaN. © 2000 American Institute of Physics.

    Elimination of secondary defects in As-implanted Si by high concentration oxygen atoms (1988)

    Notes: Arsenic precipitate-induced dislocation loops generated at the projected range Rp of As in high-dose As-implanted, annealed (100) Si are eliminated, if oxygen-atom concentrations at the Rp region are high, i.e., above about 1×1020 atoms/cm3 . This is confirmed by the following two experiments: 80 keV, 2×1016 As+/cm2, 18-nm-thick through-oxide implantation together with subsequent annealing and a double implantation of 80 keV, 2×1016 As+ /cm2 and 22 keV, 5×1015 O+ /cm2 , followed by an annealing sequence. Experimental results suggest that the bonding of several As atoms with one oxygen atom suppresses As clustering.

    Development of a grazing incidence ultrasoft x-ray monochromator for radiation biology studies (abstract) : INTERNATIONAL CONFERENCE ON SYNCHROTRON RADIATION INSTRUMENTATION TSUKABA (JAPAN) 29 AUG−2 SEPT 1988 (1989)

    Notes: Irradiation experiments on biological samples with monochromatic ultrasoft x-rays are inevitable in elucidating the initial process in radiobiological phenomena. However, intense light sources with continuous spectra in this wavelength region have not been available until recently. Synchrotron radiation is the best light source for the study because of its intense, continuous emission spectrum. The purpose of the project is to develop a grazing incidence ultrasoft x-ray monochromator for radiation biology studies using synchrotron radiation as a light source. The following characteristics are required in the monochromator, namely, (1) high throughput with moderate resolution; (2) wide beam area with uniform intensity; (3) little contamination of higher order lights; and (4) easy operation and maintenance. Considering the above requirements, a plane-grating type monochromator (PGM) is adopted. The monochromator consists of two premirrors (M1 and M2), a plane grating (1200 l/mm), a concave focusing mirror (r=12 m) and an exit slit. Two premirrors with different incident angles can be used interchangeably to eliminate higher order lights in the desired wavelength region. Wavelength of 30–70 A is available when M1 is used and 80–250 A when M2 is used. Expected wavelength resolution is 1% when the width of exit slit is 300 μm. All vacuum chambers accommodating these optical elements are bakable in order to attain ultrahigh vacuum. Wavelength is controlled by a microcomputer system equipped with a stepping motor and an encoder. This monochromator will be installed at beamline 12C at the Photon Factory, National Laboratory for High Energy Physics, and will be open to outside users in radiation biology by the end of 1988.

    Notes: : The factors affecting myosin degradation that occurred during aging following high-pressure treatment over a pressure range from 200 to 600 MPa were investigated by using SDS-PAGE and immunoblotting analysis. The immunoblot pattern of myosin in muscle stored at 37°C for 48 h after pressure treatment at 0. 1 MPa (atmospheric pressure) or 200 MPa for 5 min was similar to that of native myosin incubated with cathepsin D, whereas at 400 or 600 MPa the pattern was close to that of native myosin incubated with cathepsin B. This phenomenon was reflected in the pressure-susceptibilities of cathepsins B and D as reported in the literature (Homma and others 1994). However, these catheptic enzymes released by pressure treatment are unlikely to play a role in pressure-induced tenderization of meat.

    A ‘hot’ new twist to hair biology – involvement of vanilloid receptor-1 signaling in human hair growth control (2004)

    Notes: The functional role of VR1, which we and others have recently identified on several epithelial and mesenchymal human skin cell populations, was investigated in the human hair follicle (HF), as a prototypic epithelial–mesenchymal interaction system. VR1 immunoreactivity was confined to distinct epithelial compartments of HFs in anagen and catagen, while dermal papilla fibroblasts and HF melanocytes were VR1 negative. In organ culture, VR1 activation by capsaicin resulted in a dose-dependent and VR1-specific inhibition of hair shaft elongation, suppression of proliferation, promotion of apoptosis, and induction of catagen transformation, possibly due to upregulation of a potent hair growth inhibitor TGFβ2. Cultured outer root sheath (ORS), as well as HaCaT, keratinocytes also expressed functional VR1, whose stimulation inhibited proliferation, induced apoptosis, and elevated intracellular calcium concentration. Finally, VR1 stimulation of cultured ORS keratinocytes upregulated the expression of recognized endogenous hair growth inhibitors (IL-1β and TGFβ2) and downregulated the expression of stimulators (HGF, IGF-1, and SCF), while key differentiation markers (CK17, CK14, filaggrin, and involucrin) remained unaffected. In conclusion, VR1 is a significant novel player in human hair growth control underscoring that its physiological functions in human skin far extend beyond sensory neuron-coupled nociception.

    Notes: Paratropomyosin is a minor myofibrillar protein which in freshly prepared myofibrils is exclusively localized at the A-I junction region of sarcomeres. We investigated the ultrastructural localization of paratropomyosin in intact and postrigor myofibrils by immunoelectron microscopy. Paratropomyosin was localized as two distinct stripes at the A-I junction in intact myofibrils. It also was localized at the position corresponding to the original A-I junction in thick filament-free myofibrils (I-Z-I brushes). However, following postmortem storage, paratropomyosin was found broadly distributed in thin filaments of myofibrils.
