    Executing Formal Specifications with Concurrent Constraint Programming (2000)
    Springer
    Automated software engineering 7 (2000), S. 315-343

    Notes: Abstract We have implemented a technique for execution of formal, model-based specifications. The specifications we can execute are written at a level of abstraction that is close to that used in nonexecutable specifications. The specification abstractions supported by our execution technique include using quantified assertions to directly construct post-state values, and indirect definitions of post-state values (definitions that do not use equality). Our approach is based on translating specifications to the concurrent constraint programming language AKL. While there are, of course, expressible assertions that are not executable, our technique is amenable to any formal specification language based on a finite number of intrinsic types and pre- and postcondition assertions.

    Plot Direction and Spacing Effects on Interplot Interference in Spring Wheat Cultivar Trials (2000)
    Springer
    Crop science 40 (2000), S. 655-658

    Notes: Triticum aestivum L.) at Regina and Swift Current in 1995 and 1996. Interplot interference was evaluated with two spring wheat cultivars differing for height, Oslo (short) and Glenlea (tall). Interplot interference caused a 12% yield reduction in Oslo in the north–south rows, which was significantly greater than the 7% yield reduction in the east–west rows. The 7% yield reduction when spring-planted winter wheat separated the plots was significantly less than the 18% yield reduction when plots were adjacent. This study was conducted at fairly high latitudes and the conclusions should be restricted to higher latitudes. We conclude that spring wheat field trials with plots differing for height may have less interplot interference if rows are oriented east–west and separated with winter wheat.

    Identification of (Z)-4-tridecene from Defensive Secretion of Green Lacewing, Chrysoperla carnea (2000)

    Notes: Abstract We report the identification of a defensive secretion from the green lacewing, Chrysoperla carnea. By using combined gas chromatography–electroantennographic detection (GC-EAD), we found one major compound in the solvent extract of this secretion that elicited a significant EAD response from the antenna. Based upon its characteristic fragments from gas chromatography–mass spectrometry (GC-MS) analysis, the compound was identified as a tridecene. Dimethyldisulfide derivatization suggested that a double bond was located between positions 4 and 5 in the carbon chain. Thus, the compound was tentatively identified as a 4-tridecene. Coinjection of the extract with a mixture of the Z or E form of the synthetic 4-tridecene revealed that the unknown was (Z)-4-tridecene. EAG dose–responses showed a direct correlation to dose. Single sensillum recordings from sensilla trichodea situated on the antennae suggested the presence of receptor neurons specifically responding to this compound. An arrestment behavior was observed when tested in the Y-tube olfactometer. Preliminary field trapping results indicate that the compound is an antagonist to attraction. The avoidance behavior of predatory ants, observed when tested with the synthetic compound of this secretion further suggested a defensive function.
