We present here a study of event generators for the hadronic production of Wγ . We compare a NLO Wγ matrix element generator with the leading order calculation in Pythia . A matching scheme between a next-to-leading order Wγ matrix element generator by Baur et. al. and the Pythia parton shower is presented. The NLO package produces Wγ +0 jet and Wγ +1jet final states in the hard scattering and ...

Nature has evolved efficient strategies to synthesize complex mineralized structures that exhibit exceptional damage tolerance. One such example is found in the hypermineralized hammer-like dactyl clubs of the stomatopods, a group of highly aggressive marine crustaceans. The dactyl clubs from one species, Odontodactylus scyllarus, exhibit an impressive set of characteristics adapted for survivi...

Based on specimens collected from bats of different families, we add new species and extend the known ecological distribution and host associations of insect ectoparasites of bats in Peru. New information is provided for the distribution of 26 species of parasites (25 Diptera and 1 Siphonaptera: Ischnopsyllidae). Four species (Neotrichobius ectophyllae, Strebla galindoi, Strebla paramirabilis a...

The progress in determining the coupling constants of mesonic chiral Lagrangians is reviewed, with emphasis on the work performed in three successive European Networks (Eurodaphne I and II, Euridice). Reliable estimates of those constants are essential for making full use of next-to-next-to-leading-order calculations in chiral perturbation theory. The precision in the values of the strong coupl...

The mermithid Heleidomermis magnapapula Poinar and Mullens, a parasite of the biting midge Culicoides variipennis (Coquillett), was exposed to constant temperatures in the laboratory. Survival of the free-living stages and development times of eggs and the parasitic phase were inversely related to temperature. Average preparasite longevity was 70, 46, 42, and 22 hours at 15.6, 21.1, 26.7, and 3...

Devices/Applications/Reliability 6111 Reliability, Packaging, Testing, and Characterization of MEMS/MOEMS V (Tanner/Ramesham) 6112 Microfluidics, BioMEMS, and Medical Microsystems IV (Papautsky/Wang/Vauchier) 6113 MEMS/MOEMS Components and Their Applications III (Olivier/Tadigadapa/Henning) 6114 MOEMS, Display, Imaging, and Miniaturized Microsystems IV (Ürey/Dickensheets/Gogoi) Founding Chair M...

The mermithid parasite Heleidomermis magnapapula was maintained in larvae of the midge Culicoides variipennis for 20 months in enamel pans containing nutrient-rich water and polyester pads as a substrate. Inseminated female mermithids were introduced to the pad surface when the host was in the late second or early third-instar. Host larvae were harvested from the pans 9 days after exposure and ...

Merino sheep in Thornveld, Dorper sheep and Angora goats in inland Valley Bushveld, Angora goats and Boer goats in Valley Bushveld on the coastal plateau, and springbok, Antidorcas marsupialis, and black wildebeest, Connochaetes gnou, in Karroid Mountainveld, all in the Eastern Cape Province, were examined for the larvae of nasal bot flies. The sheep and goats were infested with the larvae of O...

Many crustaceans detect odors from distant sources using chemosensory sensilla (aesthetascs) on their antennules. The greater the flow of water through arrays of aesthetascs, the faster the access of odorant to receptors inside the aesthetascs. Stomatopods facilitate odorant access by flicking their antennules, thus increasing the relative velocity of the water reaching their aesthetascs. We us...

Protests take place for a variety of reasons. In this paper we focus on protests that have a well defined objective, that is in conflict with the objectives of the government. Hence the success or failure of a protest movement depends crucially on how the government responds. We assume that government types are private information so that governments have an interest in building a reputation to...
