ISC - An efficient probabilistic packet marking scheme (NOD-PPM)
Lecture Notes in Computer Science, 2006Co-Authors: Huifang YinAbstract:This paper describes an efficient scheme of probabilistic packet marking. The main idea is to preserve the victims' IP addresses at the routers participating in the packet marking scheme, based on the precondition that a router won't begin to marking until it receives a signal from the victim. Then, the destination address Field of IP header can be used to carry edge information without fragmenting, and the Identification Field can be used to check attack paths' validity under DDoS. We describe the scheme and discuss the number of packets required for reconstructing the attack paths, the number of false positives of attackers and the extra cost at routers in this paper.

(Z)-7-Tricosene and Monounsaturated Ketones as Sex Pheromone Components of the Australian Guava Moth Coscinoptycha improbana: Identification, Field Trapping, and Phenology
Journal of chemical ecology, 2006Co-Authors: A. R. Gibb, David M. Suckling, Bruce D. Morris, T.e. Dawson, Barry J. Bunn, D. Comeskey, J. J. DymockAbstract:Pheromone gland extracts of the Australian guava moth Coscinoptycha improbana (Lepidoptera: Carposinidae), contained four compounds that elicited responses from male moth antennae in gas chromatography-electroantennogram detection (GC-EAD) analyses. These were identified by GC-mass spectrometry as (Z)-7-tricosene (Z7-23Hy), (Z)-7-octadecen-11-one (Z7-11-one-18Hy), (Z)-7-nonadecen-11-one (Z7-11-one-19Hy), and (Z)-7-tricosen-11-one (Z7-11-one-23Hy) at a ratio of 65:23.5:1.5:10, respectively. Z7-23Hy, Z7-11-one-18Hy, and Z7-11-one-23Hy have not previously been reported as lepidopteran sex pheromone components. Z7-11-one-18Hy was active as a single component, and was synergized by Z7-11-one-23Hy but not Z7-11-one-19Hy, although the latter compound was weakly attractive as a single component. Addition of Z7-23Hy further increased attraction. The amount of the major pheromone component, Z7-11-one-18Hy in female pheromone gland extracts was estimated to be 16.4 ng/female (N = 8). Phenological data gathered over a 12-mo period in 2002 and 2003 using the binary blend indicated that moths are active throughout the year. The pheromone has already been employed to monitor the spread of C. improbana in New Zealand and detect its presence in Queensland, Australia.

Sex pheromone of the citrus flower moth Prays nephelomima: Pheromone Identification, Field trapping trials, and phenology
Journal of chemical ecology, 2005Co-Authors: A. R. Gibb, Lisa E. Jamieson, David M. Suckling, Padmaja Ramankutty, P.s. StevensAbstract:Analysis of sex pheromone gland extract of the citrus flower moth, Prays nephelomima (Lepidoptera: Yponomeutidae) by coupled gas chromatography–electroantennogram detection, revealed one electrophysiologically active compound. Structural analysis using gas chromatography, gas chromatography–mass spectrometry, and dimethyldisulfide derivatization identified this as the monounsaturated aldehyde (Z)-7-tetradecenal. Field trials in commercial citrus orchards on the North Island of New Zealand showed that (Z)-7-tetradecenal was highly attractive to male P. nephelomima. Phenology data, collected over 19 months in three commercial orchards, from traps baited with the sex pheromone at a lure loading of 300 μg on a red rubber septum, indicated that male moths may be present throughout the year, with numbers peaking in late summer and autumn.
