    Begonia fulgurata (sect. Diploclinium, Begoniaceae), a new species from northern Thailand (2017)

    Description: Begonia fulgurata, a new species from northern Thailand, is here described and illustrated. Begonia fulgurata resembles B. integrifolia, a widespread species in Southeast Asia, in having tubers, erect stem with hairy leaves and a periodically dormant habit. However, the new species is sharply distinct in its lamina densely hirsute (vs sparsely puberulous) and with maroon patches and silvery white veins (vs uniformly green or with white spots); inflorescence densely clothed with glandular hairs (vs glabrous or puberulous); staminate flowers with 2, rarely 3 (vs 4) tepals; staminate and pistillate tepals glandular hairy (vs glabrous). As a deciduous species with basal tubers, together with an erect stem, ovate to broadly ovate leaves, 3-locular ovary, it may be mistaken as a dwarf plant of B. grandis, one of the most widely distributed species in China and the type species of sect. Diploclinium. However, B. fulgurata differs in its leaf upper side with fine silvery (vs green) veins; inflorescence densely glandular hairy (vs glabrous), staminate tepals 2 or rarely 3 (vs 4) and pistillate tepals 5 (vs 3), and ovary glandular hairy (vs glabrous).

    A parallel algorithm for estimating the secondary structure in ribonucleic acids (1990)
    Springer
    Biological cybernetics 63 (1990), S. 337-340 
    Details
    ISSN: 1432-0770

    Notes: Abstract A parallel algorithm for estimating the secondary structure of an RNA molecule is presented in this paper. The mathematical problem to compute an optimal folding based on free-energy minimization is mapped onto a graph planarization problem. In the planarization problem we want to maximize the number of edges in a plane with no two edges crossing each other. To solve a sequence of n bases, n(n — 1)/2 processing elements are used in our algorithm.

    Optimization of the Viability of Probiotics in a New Fermented Milk Drink by the Genetic Algorithms for Response Surface Modeling (2003)

    Notes: : Calcium gluconate (0.0 to 0.5%), sodium gluconate (0.0 to 1.0%), and N-acetylglucosamine (0.0 to 1.0%) were added to skim milk to retain the viability of Lactobacillus acidophilus and Bifidobacterium longum. To carry out response surface modeling, the regression method was performed on experimental results to build mathematical models. The models were then formulated as an objective function in an optimization problem that was consequently optimized using a genetic algorithm approach to obtain the maximum viability of the probiotics. The genetic algorithms (GAs) were examined to search for the optimal value. The results indicated that GAs were very effective for optimizing the activity of probiotic cultures.

    Factors Affecting the Water-Holding Capacity of Fibrinogen/Plasma Protein Gels Optimized by Response Surface Methodology (2002)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 67 (2002), S. 0

    Notes: : Response surface methodology (RSM) was applied to optimize the water-holding capacity (WHC) of fibrinogen/plasma protein gels heated at 75°C for 10 min to develop a new edible gel. The effects of varying the amount of fibrinogen, plasma protein, calcium, and pH were evaluated to optimize the WHC using RSM. Estimation of the overall effects of the 4 factors on the gels revealed that the pH and concentrations of fibrinogen and plasma protein significantly affected the WHC of the gels (p 〈 0.05). The WHC increases with the concentrations of plasma protein only at concentrations lower than 8%. At lower plasma concentrations, fibrinogen addition had only minimal influence on the WHC. The optimum WHC values were predicted by the RSREG procedure of the SAS program. Model verification was performed by additional independent trials, and the resulting experimental values were very close to the predicted ones with no significant difference (p 〉 0.05).

    Characterization of Polysaccharide and Volatile Compounds Produced by Kefir Grains Grown in Soymilk (2002)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 67 (2002), S. 0

    Notes: : The characteristics of polysaccharides isolated from milk and soymilk kefir grains, and the composition of flavor and volatile compounds from soymilk kefir were investigated. Soymilk kefir grains revealed lower polysaccharide content than milk kefir grains, with a polysaccharide profile consisting primarily of glucose and galactose, with the former predominating. The apparent molecular weight of the polysaccharide was estimated at 1.7 × 106 Da. In comparison to nonfermented soymilk, the concentrations of the key volatile compounds for soymilk kefir (such as acetaldehyde, acetone, diacetyl, and ethanol) increased, while n-hexanal concentration decreased. The acetaldehyde level for soymilk kefir was slightly higher, but levels for the other volatile compounds were lower than for milk kefir.

    Properties of plasma-enhanced chemical-vapor-deposited a-SiNx:H by various dilution gases (1994)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 76 (1994), S. 3645-3655

    Notes: The effects of dilution gases on hydrogenated amorphous silicon nitride (a-SiNx:H) films were investigated. Silane and ammonia were used as the reactive species, while nitrogen, helium, hydrogen, and argon were used as the dilution gases in a plasma-enhanced chemical vapor-deposition system at a substrate temperature of 300 °C. The electrical, physical, and chemical properties of the a-SiNx:H films were found to be highly sensitive to the various kinds and flow rates of the carrier gases in the deposition. Additionally, the physical properties of growth rate, refractive index, and etching rate were also investigated. The hydrogen bonding configuration was explored by infrared spectroscopy. The total hydrogen concentrations for all a-SiNx:H films were observed to be smaller than 3.0×1022 cm−3. The electrical properties were characterized by I-V and C-V measurements in metal-insulator-semiconductor structures. The breakdown strength was determined at the current density of 3 mA/cm2; in addition, the dominant mode of electronic conduction would appear to be the Poole–Frenkel emission. The interface trap state density Dit which ranged from 3.4×1011 to 1.3×1012 cm−2 eV−1 was evaluated by the C-V characteristics. Finally, the influences of the gas dilution in the a-SiNx:H films, as applied to the devices, were investigated by using the hydrogenated amorphous silicon thin-film transistors (a-Si:H TFTs). Analyses of the transfer characteristics of the TFT devices revealed that the density of deep gap states is 4×1012 cm−2 eV−1 and the field-effect mobility μFE is changing from 0.37 to 1.45 cm2/V s.
