    Notizen: The feasibility of superconducting strips as position-sensitive detectors for α particles was investigated. For this purpose films have been prepared of different materials and dimensions using standard evaporation and laser ablation in an UHV system. Films were patterned into strips and current-biased strips were irradiated with 5.5 MeV α particles. The energy deposited by the particle in the strip creates a normal-conducting region, which in turn causes a voltage drop. The time evolution of the voltage drop across the strip as a function of bath temperature and bias current has been investigated. Information about the site of the strip hit by the α particle was obtained from monitoring the propagating normal-conducting zones. A lateral position sensitivity of ±30 μm for a tantalum strip detector has been achieved. The propagation of normal-state zones in the strip cannot provide information on the energy of the particle. A model describing the time evolution of a normal-conducting zone in a current-biased superconducting strip was used to test and interpret the experimental results and allows one to estimate the thermal conductivity of the strip material and the heat transfer from the strip into the substrate. © 1995 American Institute of Physics.

    Notizen: The ensemble of conduction electrons is treated as a fluid whose collective motion is described by the Navier–Stokes and Maxwell equations. Under simplifying conditions, Ohm's law is generalized for the stationary case. The profile of the current density is shown. Geometry-dependent effective conductivities are derived for circular cylinders and plates with rectangular and square cross sections, in good agreement with size effect experiments. A compilation of the fitting parameters, bulk resistivity, and adherence length used for Cu, Ga, and CoSi2 is presented in the temperature range 300→0 K for dimensions between 1 nm and 2 mm.

    Notizen: We have grown superconducting films on the technologically important sapphire substrates by CO2 pulsed laser ablation from fully superconducting targets of Bi2Sr3−xCaxCu2Oy followed by appropriate post-annealing. The composition of the films was found to deviate slightly from the target. Nevertheless, films with metallic resistivity decreasing between room temperature and 95 K, Tc(onset) of about 90 K and Tc(zero) of 72 K have been obtained. Magnetoresistance measurements in fields up to 12.85 T give a value of dHc2/dT of 1.6 T/K, which is intermediate between reported values of parallel and perpendicular Hc2 of fully aligned thin films. The implied partial orientation is consistent with the morphology seen by scanning electron microscopy.

    Notizen: We present a description of electrorheological fluids in terms of an electric field induced phase transition at a critical electric field Ec. Theoretically, we find that as the applied field exceeds Ec, the osmotic pressure becomes negative and the liquid experiences a phase transition to a solid phase. Ec is experimentally determined as a function of concentration in one system. Our theoretically predicted phase diagram is in reasonable agreement with our experimental data.

    Notizen: This study examines the economics of the timing of adoption of SFAS No. 13, Accounting for Leases by Lessees. We analyzed actual debt contracts of the affected firms to determine whether they were based on GAAP or Non-GAAP accounting rules. We also examined what actions were taken by management to alleviate the negative effects of complying with SFAS No. 13. The results indicate that late adopters had a higher percentage of debt convenants based on GAAP measures, and that the late adopters would have experienced significant increases in closeness to default had they adopted SFAS No. 13 early. The results also indicate that by choosing late adoption, the firms were able to reduce the expected negative effects of the new accounting standard on financial statements.

    Notizen: This study examines whether Hong Kong managers choose “benchmark” or “alternative” valuation method for investment securities, after the Hong Kong SSAP 24 became effective starting with fiscal-year ending December 31, 1999. Tests are conducted on a sample of 292 firms, out of which 155 Hong Kong firms reported unrealized gains and losses and 128 firms that did not report holding gains/losses, but reported investment securities.The findings indicate that firms with strong relative performance, i.e. current year's EPS higher than that of the last year, chose the alternative valuation method when the investment securities had holding gains and recognized the unrealized holding gains in the equity section of the balance sheet. This finding is consistent with the Cookie Jar hypothesis because these holding gains would be used in the income statement in future periods, when needed. With regard to firms with strong relative performance and holding losses, the findings indicate that the benchmark valuation was used. The losses were reported in the income statement to the extent that they did not reduce the EPS below that of the last year. This finding is consistent with the Income Smoothing Hypothesis, because the use of benchmark valuation reduced EPS of the current year to bring it in line with that of the last year. Evidence on firms with weak economic performance and holding gains or losses provided weak support to the Income Smoothing Hypothesis and Big Bath Hypothesis. Additionally, the results indicate that the firms with high debt-equity ratio preferred the benchmark method and recorded securities at cost. This treatment provided managers with an opportunity to liquidate or reclassify the securities in future periods and use the accrued gains, when needed. The findings are inconclusive with regard to the impact of bonus plan on the choice of valuation method.
