    Description: Surface Meteorology, upper ocean current, and hydrographic measurements, collected along a repeated survey pattern and from a central mooring in the western equatorial Pacific during late 1992 to early 1993, were used to analyse upper ocean momentum balances on the intraseasonal time scale. Wind stresses derived from meteorological measurements were compared with numerical weather prediction products. Advection terms in the momentum equations were estimated by planar fits to the current and hydrographic data. Pressure gradient terms were derived from planar fits to the dynamic heights calculated from the hydrographic data, referenced by balancing the momentum equation in a selected layer below the mixed layer. Under prevailing westerly winds, westward pressure gradient forcings of 2x10-7 m s-2 were set up in the western equatorial Pacific, countering the surface wind, while the total advection tended to accelerate the eastward momentum in the surface layer. During both calm wind and westerly wind burst periods, zonal turbulent momentum fluxes estimated from the ocean budgets were comparable with those estimated from microstructure dissipation rate measurements and with zonal wind stresses, so that the zonal momentum could be balanced within error bars. The meridional momentum balances were noisier, which might be due to the fact that the short meridional length scale of the equatorial inertial-gravity waves could contaminate the dynamic signals in the mixed temporal/spatial sampling data, so that the meridional gradient estimates from the planar fits could be biased.

    Characterization of excimer-laser-annealed polycrystalline silicon films grown by ultrahigh-vacuum chemical vapor deposition (2000)

    Notes: Polycrystalline silicon (poly-Si) films grown by ultrahigh-vacuum chemical vapor deposition (UHVCVD) system and then annealed by excimer laser at room temperature have been investigated for the applications in polycrystalline silicon thin-film transistors (poly-Si TFTs). The results showed that the grain size of the laser-annealed poly-Si film decreased with laser energy density when a lower laser energy density below 157.7 mJ/cm2 was used. At about the threshold laser energy density (∼134.5 mJ/cm2), the finest grain structure could be obtained due to the partial melting in the top layer of the film. When the energy density of the excimer laser was larger than the threshold energy density, the large grain growth was initiated. The largest grain structure could be obtained at ∼184 mJ/cm2, while its surface roughness was better than that of the nonannealed UHVCVD poly-Si films. The surface roughening was suggested to arise from the specific melt-regrowth process but not the rapid release of hydrogen or capillary wave mechanism derived from laser-annealed amorphous silicon. By use of the laser-annealed UHVCVD poly-Si films as the active layer, the fabricated poly-Si TFT exhibited a field-effect mobility of 138 cm2/V s, a subthreshold swing of 0.8 V/dec, a threshold voltage of 3.5 V, and an on/off current ratio of ∼106. © 2000 American Institute of Physics.

    New use of broomcorn millets for production of granular cultures of aphid-pathogenic fungus Pandora neoaphidis for high sporulation potential and infectivity to Myzus persicae (2003)

    Notes: Glutinous broomcorn millets from the crop Panicum miliaceum were first used as substrate to produce granular cultures of Pandora neoaphidis, an obligate fungal pathogen specific to aphids. Carrying a water content of 36.5% after being steamed in a regular autoclaving procedure, millet grains of each 15 g (dry weight) in a 100-ml flask were mixed with 3 ml modified Sabouraud dextrose broth containing half a mashed colony of P. neoaphidis grown on egg yolk milk agar and then incubated at 20°C and a light/dark cycle of 12 h/12 h for 21 days. Based on individually monitoring conidial production potential of 20 millet grains sampled from an arbitrarily taken flask at 3-day intervals, the millet cultures incubated for 6–15 days were capable of producing 16.8–23.4×104 conidia per millet grain with conidial ejection lasting for up to 6 days. The cultured millet grains individually produced significantly more conidia than apterous adults of Myzus persicae killed by P. neoaphidis (8.4×104 conidia per cadaver) and sporulated twice longer. The modeling of time–dose–mortality data from bioassays on M. persicae apterae exposed to conidial showers from the cultured millet grains and the mycelial mats produced in liquid culture resulted in similar estimates of LC50 (millets: 21.4, 7.3, and 4.9 conidia mm−2 on days 5–7 after exposure; mycelial mats: 22.1, 10.6, and 7.7 conidia mm−2) although the LT50 estimated at a given conidial concentration was slightly smaller for the millet cultures than for the mycelial mats. This indicates that the millet grains cultured with P. neoaphidis produced conidia as infective as or slightly more infective to M. persicae than those from the mycelial mats. Based on the sporulation potential, infectivity, and ease and cost of the millet cultures, the method developed in this study highly improved in vitro cultures of P. neoaphidis and may adapt to culturing other entomophthoralean fungi for microbial control of insect pests.

    Factors affecting the sporulation capacity during long-term storage of the aphid-pathogenic fungus Pandora neoaphidis grown on broomcorn millet (2005)

    Notes: Aphid-pathogenic fungus, Pandora neoaphidis, grown on broomcorn millet possesses greater sporulation capacity (Cs) than aphid cadavers. The most sporulating cultures (32.0 × 104 spores millet−1 grain) with water content (Cw) of 48.7% were prepared by incubation at 20 °C for 15 days and used to study the effect of temperature and humidity on Cs during long-term storage. Cultures were sealed with paper to retain ambient humidity, with parafilm for saturated humidity, or kept in 85% and 98% RH chambers. The Cw and Cs were monitored during 200-day storage at 5–20 °C. The paper-sealed cultures at 5 °C, associated with 21–25% of Cw, were best preserved and their 120-day Cs was similar to that of the fresh cadavers. Consistently or variably high RH at 5 °C resulted in significantly higher Cw and lower Cs despite longer viability. The regimes at ?10 °C preserved the cultures for ?40 days. The observations fit well to the logistic model Cs= 35.28/{1 + exp[−2.36 + (−0.003Cw+ 0.001CwT)t]} (r2= 0.95) for all regimes of temperature (T) or Cs= 35.55/[1 + exp(−2.33 + 0.001Cwt)] (r2= 0.93) at 5 °C only. The rate of decline of Cs of −0.003Cw+ 0.001CwT or 0.001 Cw over days (t) highlights the primary effect of Cw. The daily Cs-decline rates obtained for the best-stored cultures and air-dried cadavers stored at 5 °C were surprisingly identical. The results suggest a possible cheap method for preparing and storing large quantities of P. neoaphiodis inocula.

    Notes: In this paper, we simulate the magnetization dynamic processes of the multilayer films,and calculate their hysteresis loop areas using Monte Carlo method. The simulated results indicatethat, the size and anisotropy strength of the anisotropy multilayer films influence evidently thedynamic phase transition, and the phase transition temperature increases with enhancing values ofthe anisotropy constant and layer thickness. It is also found that, with increasing number of layers offilms, the value of α decreases, while the magnitudes of β and γ increase. On the contrary, withincreasing anisotropy strength, the value of α increases, while the magnitudes of β and γ reduce
