    Notes: Ni–Fe/FeMn bilayers were deposited by using dual ion beam sputtering apparatus. In order to promote (111) orientation in γ-FeMn layers and to exhibit exchange bias field Hex, Si and/or silicon nitride (Si3N4) layers were deposited as buffer layers. Although silicon nitride (Si3N4) buffer layers did not improve (111) orientation in FeMn layers, as well as in Ni–Fe layers, an amorphous Si buffer layer only 1 nm thick improved (111) orientation in FeMn layers and increased Hex to above 100 Oe. FeMn/Ni–Fe bilayers deposited on Si(0.5 nm)/Si3N4(1 nm) bilayered buffer layer also exhibited high Hex of about 130 Oe. This result implies that the ultrathin a-Si buffer layer was effective in improving (111) orientation in Ni–Fe layers. Very thin Si/Si3N4 bilayers may be applicable as dielectric layers in tunneling magnetoresistive spin valve devices. © 1999 American Institute of Physics.

    Notes: GYROTRON FU IV, a frequency tunable gyrotron for spectroscopy in the submillimeter wavelength range using a 17 T superconducting magnet, has been designed and constructed. Simulations predict that the gyrotron will emit radiation at high frequencies up to 394 GHz (TE041 cavity mode) at the fundamental of the electron cyclotron frequency, up to 858 GHz (TE091 mode) at the second harmonic and up to 1301 GHz (TE8 11 1 mode) at the third harmonic. Preliminary experimental results have demonstrated operation from 158 to 443 GHz at the fundamental and from 336 to 838 GHz at the second harmonic. Output powers are several hundred watts and efficiencies several percent. © 1995 American Institute of Physics.

    Notes: The development of a submillimeter wave, high-harmonic gyrotron using a 12 T superconducting magnet is described. It has achieved frequencies as high as 636 GHz (corresponding to a wavelength of 472 μm) in second harmonic operation. Many resonances could be obtained as a single mode without competing modes. Typical output power is several hundred watts at both the fundamental and the second harmonic. At low beam currents (Ib∼0.5 A), third harmonic operation has been obtained. © 1995 American Institute of Physics.

    Symmetries and dissociation dynamics of F 1s core excited states of BF3 (1997)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: Using the photoelectron–energy-selected photoion coincidence technique, we find that photoions of BF3 with kinetic energy larger than 4 eV are predominantly F+ in the F 1s ionization region whereas B+ is more intense than F+ at the F 1s→2a2″ excitation. Two partial cross sections σ|| and σ⊥ for A1′→E′ parallel and A1′→A2″ perpendicular transitions are obtained from the angular distribution measurement of energetic photoions and the symmetries of some F 1s core excited states are confirmed. The dissociation dynamics of the F 1s−12a2″ core excited state are discussed in detail. © 1997 American Institute of Physics.

    Angle-resolved photoelectron and photoion study on the shape resonance in the B 1s ionization region of BF3 (1997)

    Notes: Angle resolved photoelectron and photoion spectroscopy has been used to investigate the e′ shape resonance just above the B 1s ionization threshold of BF3. The B 1s photoelectron asymmetry parameter β is ∼0 in the vicinity of the peak of the shape resonance and increases with increase in photon energy, illustrating good agreement with a theoretical prediction. From the angular distribution measurement of energetic F+ fragments following B 1s photoionization, we have decomposed the photoionization cross section into two components σe′ and σa2″ for the B 1s→e′ parallel and B 1s→a2″ perpendicular transitions and confirmed that the shape resonance is in the e′ symmetry component. © 1997 American Institute of Physics.

    Measuring the Social-Care Service Needs of Impaired Elderly People in Japan (1996)

    Notes: This study aims to measure objectively and/or estimate the needs of impaired elderly persons and their families for social care services. The research was carried out in Maebashi, a medium size Japanese city. In our study, ‘impaired elderly persons’ included both physically and/or mentally impaired persons. In total, 693 impaired elderly persons and their families were classified according to 20 specific types of need: these ‘need types’ were cross-tabulated with two sets of factors: (1) Severity of impairments and (2) Difficulty of caregivers in providing the required care. A standard model of the service provision necessary for each ‘need type’ was established through group consultation with social care service professionals. Finally, the total amount of each service required in the city was calculated. Major findings are: (1) Our estimates indicate that 7.1 per cent of all persons 65 and over residing in Maebashi City were physically and/or mentally impaired to a certain degree. (2) Forty per cent of these elderly people were being cared for by caregivers who themselves had serious difficulties. (3) The demand for social care services in local Japanese cities is high. In order for this demand to be met a substantial expansion of both nursing home care and in-home care services is required.

    AN IMPORTANT EFFECT OF TSH ON PROSTACYCLIN CONCENTRATION IN PORCINE THYROID CELLS (1984)

    Notes: 1. Fresh thyroid slices obtained from normal pigs contained prostaglandin E2 (PGE2), prostaglandin F2α (PGF2α) and prostacyclin (PGI2, measured as the end metabolite, 6-keto PGF1α), but the concentrations of PGI2 exceeded those of PGE2 and PGF2α. A preferential increase of PGI2 was produced when the slices were exposed to a large dose of TSH (thyroid-stimulating hormone).2. When thyroid cells were isolated and cultured in the absence of TSH, thyroidal concentrations of PGI2, PGE2 and PGF2α were about equal. When the cells were acutely exposed to a large dose of TSH, intrathyroidal concentration of prostaglandin increased significantly, but the relative concentrations of prostaglandins were not markedly altered.3. When thyroid cells were cultured in the presence of a small dose of TSH, relative concentrations of thyroidal prostaglandins were comparable to those of fresh thyroid slices, as a result of a preferential increase of PGI2 and decreases of PGE2 and PGF2α. Further increase of PGI2 was induced when the cells cultured with TSH were acutely exposed to a large dose of TSH.4. It is concluded that although cells contain PGE2, PGF2α and PGI2, a preferential accumulation of PGI2 is found only when thyroid cells are chronically stimulated by TSH.

    The relationship between myocardial oxygen consumption and total work obtained by a new left ventricular model (1984)

    Notes: Summary The relationship between myocardial oxygen consumption ( $$M\dot VO_2 $$ ) and left ventricular work was examined experimentally, assuming that the left ventricle is equivalent to an electrical current source generator consisting of parallel source resistance (Ri) and constant generator current (I0). The internal and external work can be calculated as (Ri×I1 2) and (Rp×I2 2) in this model, where I1 is current of source resistance, Rp is peripheral resistance and I2 is cardiac output. The experiments were performed with a blood-perfused isolated ejecting canine heart preparation in which the hydraulic model, simulated to an aortic input impedance, was attached to the aortic root. The peripheral resistance was changed in a stepwise fashion and left ventricular pressure, cardiac output and $$M\dot VO_2 $$ were measured. The calculated total work showed a close linear correlation with the $$M\dot VO_2 $$ which suggested that the left ventricle can be regarded as a current source generator and the total work as a main mechanical factor in determining the $$M\dot VO_2 $$ .

    Notes: Abstract An evolutional system design methodology for generating conceptual moving structural designs by computer is prognosed in which multiobjective optimization strategies are used. In this methodology, operators for evolution are defined as factors for causing evolution, so that actions by these operators on prior design solutions will generate new design solutions. Here, a number of environments are prepared, each of which has different evaluative functions expressed as multiobjective optimization problems. The evolution of design solutions thus occurs in a variety of environments. A given environment can be considered as imposing a set of criteria in which specific abilities are crucial or advantageous. Using a variety of environments to generate solutions has advantages: (1) a broader range of solutions is obtained, and (2) by moving a solution generated in one environment to a different one, additional “species” of solutions can be generated to good advantage. The proposed methodology is applied to computer-generated moving structural systems consisting of arms and joints, as well as the data for moving these structures.
