    Notes: We have measured the transport critical current density (Jc) in epitaxial quality films of YBa2Cu3O7−δ some of which were covered by thin (10 nm) Ag films. The films, both with and without Ag, had Jc values greater than 106 A/cm2 in liquid nitrogen. The effect of the Ag was to greatly reduce the dependence of Jc on external magnetic fields in the case where the field was oriented in the plane of the film, that is, perpendicular to the c axis. It is unlikely that the effect is simply due to altered surface pinning, although qualitative agreement with critical state models is observed.

    Notes: A current controlled delay in the time of flight of electrical picosecond pulses in a YBa2Cu3O7 spiral delay line has been investigated using optoelectronic sampling techniques. The transmission line is a microwave stripline on the LaAlO3 substrate and is passivated with the contact pads open. The measured delay time clearly shows a squared dependence on the applied current, in good agreement with Ginzburg–Landau theory for the case of a uniform current density through a thin film. © 1994 American Institute of Physics.

    High-TC superconductor-normal metal-superconductor Josephson microbridges with high-resistance normal metal links (1991)

    Notes: We have developed an in situ process for fabricating high transition temperature superconductor-normal metal-superconductor microbridges using a step edge to define the normal metal length. Critical current-normal resistance products over 1 mV have been measured at low temperature in devices with high-resistivity Ag-Au alloy bridges. Results on samples with Ag bridges are compared with the alloy data as an initial test of recent theories of SNS Josephson junctions. Josephson effects have been demonstrated in these devices at temperatures higher than 80 K. Clearly defined rf steps have been observed, with power dependence qualitatively similar to theoretical predictions.

    Large area double-sided YBa2Cu3O7−δ films grown by single-source metal-organic chemical vapor deposition (1995)

    Notes: Thin films of YBa2Cu3O7−δ were sequentially grown on both sides of 3 in. diameter LaAlO3 substrates by a single-source MOCVD technique to facilitate the fabrication of double-sided high temperature superconductor microwave devices. YBCO films on both sides of the LaAlO3 substrates had thicknesses greater than 4000 A(ring), Tc's of 87–88.5 K, and microwave surface resistances as low as 23 mΩ at 94 GHz and 77 K (scaling to 260 μΩ at 10 GHz). It was found that the substrate temperature, brought to the desired value by radiant heating, played a critical role in the deposition of very low surface resistance YBCO films. Microwave bandpass filters with a 19-pole forward coupled configuration were fabricated from these films. The filters showed excellent performance with dissipation losses as low as 0.5 dB. © 1995 American Institute of Physics.

    Adenoviruses isolated in the Stockholm area during 1987–1992: restriction endonuclease analysis and molecular epidemiology (1994)

    Notes: Summary Adenoviruses recovered from the northern Stockholm area during 1987–1992 have been subjected to restriction endonuclease analysis. Adenoviruses of all subgenera (A-F) were represented and a considerable degree of serotype variation was seen, e.g. the rarely encountered subgenus A viruses were frequently isolated in the present study. Of 16 subgenus A isolates, Ad31 predominated with 12 strains which were equally distributed into the DNA-variants D2 and D7. Analysis of 38 Ad3 isolates revealed four DNA-variants: D1, D3, D10, and “Sto1”. The ten Ad7 isolates belonged all to the DNA-variant D5 of Ad7. Of 27 Ad1 strains, 11 belonged to D10, followed by the DNA-variants D4 and D7 with four strains each. Among Ad2 isolates, D2 or D2-like strains prevailed (23/28). Of six Ad5 strains, three belonged to the DNA-variant D2. The most notable subgenus D event was a nosocomial outbreak of keratokonjunctivitis due ot Ad19a. In addition, a collection of heterogenous subgenus D strains was detected, most of which untypable by RE-analysis. Among the six Ad4 isolates of subgenus E, both genomic clusters (p and a, respectively) of Ad4 were recognized. Concerning the clinical important subgenus F adenoviruses, only two strains of Ad40 were detected as compared to 12 strains of Ad41, all of which ascribed to the DNA-variant D12 of Ad41.

    Characterization of two divergent adenovirus 31 strains (1993)

    Notes: Summary Two divergent strains of adenovirus type 31 were analyzed by neutralization test and restriction endonuclease (RE) patterns in an effort to find the basis for their genetic variability. One strain, isolated from the throat of a child in Maryland during an upper respiratory illness in 1968, was partially neutralized by Ad 31 antisera (to 16-fold lower than homologous titer) while its own antiserum fully neutralized prototype Ad 31 virus, but shared only 9% of comigrating RE fragments with Ad 31 prototype (vs. 30% with Ad 18 prototype); however, PCR tests specific for the inverted terminal repeat (ITR) sequence of Ads 12 and 18 were negative. The other strain, recovered from a stool sample from an infant with diarrhea in Georgia in 1979, was inhibited by Ad 31 antiserum to within 4-fold homologous titer, but shared only 15% of comigrating fragments with Ad 31 prototype (vs. 91% with Ad 18 prototype); ITR-specific PCR tests with this virus were positive for Ad 12/Ad 18. These data suggest that both strains are from separate evolutionary lines of Ad 31 unrelated to all other isolates studied to date by RE analysis, and that the partial neutralization by prototype Ad 31 antisera might represent small mutations in the hexon gene.
