    Notes: Deep level transient spectroscopy (DLTS) was used to obtain the energy level and the capture characteristics of InAs self-assembled quantum dots embedded in GaAs. A specially designed structure was used for the DLTS measurement for enhanced resolution. This structure allows us to detect capacitance relaxation signal from a single layer of quantum dots and to separate this signal from those of the DX centers inside the structure. The DLTS spectra with different filling pulses and different rate windows provide clear information on the energy level and the capture characteristics of the quantum dots. © 2001 American Institute of Physics.

    Hole Schottky barrier height enhancement and its application to metal–semiconductor–metal photodetectors (2001)

    Notes: Hole Schottky barrier heights on GaAs have been studied experimentally by using a conventional metal–semiconductor–metal photodetector (MSMPD) structure. The Schottky barrier height for holes was obtained directly by the hole-current dominated dark current measurement of the MSMPD. With a thin, highly doped surface layer, control of the Schottky barrier heights for holes from 0.48 to 0.79 eV was obtained. By using these engineered Schottky contacts in the MSMPDs, over three orders of magnitude reduction in the dark currents of the MSMPDs was achieved. © 2001 American Institute of Physics.

    Microwave effects on YBa2Cu3Oy Josephson junctions with step-edge, bi-epitaxial, and sandwich geometries (1995)

    Notes: Fabrication and characterization of YBa2Cu3Oy Josephson junctions with step-edge, bi-epitaxial, and sandwich geometries are performed in this study to investigate the effects of microwave irradiation on the I–V characteristics. I–V curves under microwave irradiation reveal Shapiro steps. The width of the constant voltage steps were modulated by the microwave power. The period of the magnetic induction ΔB detected from the V–Φ curves for superconducting quantum interference devices is temperature dependent. Additionally, Tc and Ic of the proximity sandwich junctions are enhanced by the microwave irradiation. © 1995 American Institute of Physics.

    Selective growth of single InAs quantum dots using strain engineering (2002)
    Woodbury, NY : American Institute of Physics (AIP)

    Topics: Physics
    Notes: A method to achieve ordering and selective positioning of single InAs self-assembled quantum dots (QDs) has been developed. The selective growth was achieved by manipulating the strain distribution on the sample surface. The QDs are formed on predesigned mesas with added strain. Single dots were obtained on small mesas. Using this technique, two-dimensional single QD arrays have been achieved. © 2002 American Institute of Physics.

    Notes: : The effects of erythritol on physical and sensory characteristics of chiffon cakes were studied. The results showed that chiffon cakes prepared with 25%, 50%, 75%, and 100% replacement of sucrose with erythritol were lighter in crust and crumb and less sweet in crumbs than those with sucrose. There were no differences in the specific gravity of cake batter, volume, and moisture content between cakes prepared with sucrose or erythritol. Results from sensory evaluation also showed no significant differences in crumb color, moistness, and tenderness for any cakes.

    PHYTOPLANKTON IN THE FOX CHAIN OF LAKES (1979)

    Notes: : As part of a comprehensive water quality investigation on the Fox Chain of Lakes during May to October 1975, water samples from the Chain and Cedar Lake (reference) at 25 locations were collected weekly or bi-weekly to determine the species and densities of algae. The results have been evaluated for algal composition, density, and succession for each location.Sixty-four algal species were recovered from 414 samples. The number of species per sampling location varied from 10 at Channel Lake and Lake Marie to 26 on Fox Lake (main) and Grass Lake. Blue green algae were predominant and occurred at 25 of the 25 sampling stations. They consisted mainly of Aphanizomenon flos-aquae. The only flagellate of importance was Ceratium hirundinella, and significant concentrations of this organism were limited to Channel Lake and Lake Catherine. The only green alga bloom was created by Ulothrix variabilis on the waters of Pistakee Lake. Diatoms were quite significant on the shallower water bodies.Algal densities ranged from about 25 to 14,000 cts/ml. The highest count occurred on Mineola Bay. Other high counts (〉10,000 cts/ml) observed were waters taken from Channel Lake, Grass Lake, and Fox Lake (main). In Grass Lake, 60 percent of the collections had algal densities in excess of 2,000 cts/ml. Most of these were the diatom Cyclotella meneghiniana.

    Low temperature CO oxidation over Au/TiO2 and Au/SiO2 catalysts (1993)

    Notes: Abstract After a high-temperature reduction (HTR) at 773 K, TiO2-supported Au became very active for CO oxidation at 313 K and was an order of magnitude more active than SiO2-supported Au, whereas a low-temperature reduction (LTR) at 473 K produced a Au/TiO2 catalyst with very low activity. A HTR step followed by calcination at 673 K and a LTR step gave the most active Au/TiO2 catalyst of all, which was 100-fold more active at 313 K than a typical 2% Pd/Al2O3 catalyst and was stable above 400 K whereas a sharp decrease in activity occurred with the other Au/TiO2 (HTR) sample. With a feed of 5% CO, 5% O2 in He, almost 40% of the CO was converted at 313 K and essentially all the CO was oxidized at 413 K over the best Au/TiO2 catalyst at a space velocity of 333 h−1 based on CO + O2. Half the chloride in the Au precursor was retained in the Au/TiO2 (LTR) sample whereas only 16% was retained in the other three catalysts; this may be one reason for the low activity of the Au/TiO2 (LTR) sample. The reaction order on O2 was approximately 0.4 between 310 and 360 K, while that on CO varied from 0.2 to 0.6. The chemistry associated with this high activity is not yet known but is presently attributed to a synergistic interaction between gold and titania.

    IGF-1 Levels Predict HCC Treatment Outcomes (2012)
    The American Association for Cancer Research (AACR)
    Details
    Publication Date: 2012-07-17
    Description: Purpose: Patients with liver cirrhosis or hepatocellular carcinoma (HCC) have decreased serum insulin-like growth factor (IGF)-1 levels. We evaluated whether IGF-1 levels were associated with the outcomes of patients with advanced HCC treated with systemic antiangiogenic therapy. Experimental Design: The study was based on patients with advanced HCC who were enrolled in two clinical trials evaluating first-line combination antiangiogenic therapy. Serum samples were collected before treatment and four to six weeks after the start of treatment. The levels of IGF-1, IGF-2, and IGF-binding protein-3 (IGFBP3) were analyzed for their associations with treatment outcomes. Results: A total of 83 patients were included in the study. Patients who had high (≥the median level) baseline IGF-1 levels had significantly higher disease control rate (DCR) than patients who had low (〈the median level) levels (71% vs. 39%, P = 0.003). The levels of posttreatment IGF-1, and pre- or posttreatment IGF-2 and IGFBP3 were not associated with DCR. Patients with high baseline IGF-1 levels, compared with patients with low levels, had significantly longer progression-free survival (PFS; median, 4.3 vs. 1.9 months, P = 0.014) and overall survival (OS; median, 10.7 vs. 3.9 months, P = 0.009). The high baseline IGF-1 level remains an independent factor associated with favorable PFS and OS in multivariate analysis. Conclusions: High pretreatment IGF-1 levels were associated with better DCR, PFS, and OS of patients who received antiangiogenic therapy for advanced HCC. This finding warrants validation in large studies. Clin Cancer Res; 18(14); 3992–7. ©2012 AACR .
