Attraction of \u3ci\u3ePedilus Lugubris\u3c/i\u3e (Coleoptera: Pyrochroidae) to \u3ci\u3eEpicauta Murina\u3c/i\u3e and \u3ci\u3eEpicauta Fabricii\u3c/i\u3e (Coleoptera: Meloidae) and New Food Plant Records for \u3ci\u3eEpicauta\u3c/i\u3e Spp.

Pedilus lugubris was found associated with Epicauta murina feeding on Lathyrus venosus foliage and with E. fabricii feeding on Lupinus perennis flowers. Epicauta cinerea and E. funebris were found feeding on foliage of Anemone canadensis and Physalis heterophylla, respectively. This is the first reported association of P lugubris with any species of Epicauta, and the first reported use of Lathyrus venosus by E. murina, of Lupinus perennis by E. fabricii, of Anemone canadensis by E. cinerea and of Physalis heterophylla by E. funebris

The Alien \u3ci\u3eHippodamia Variegata\u3c/i\u3e (Coleoptera: Coccinellidae) Quickly Establishes Itself Throughout Wisconsin

(excerpt) Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae) is a Palaearctic species that was first reported to be established in the Nearctic near Montreal, Quebec, in 1984 (Gordon 1987). Since then, this small beetle has been expanding its range in North America, a process summarized by Gardiner and Parsons (2005). It was first reported from Michigan in 2005 (Gardiner and Parsons 2005) and from Ohio in 2007 (Pavuk et al. 2007)

Development of theoretical models of integrated millimeter wave antennas

Extensive radiation patterns for Linear Tapered Slot Antenna (LTSA) Single Elements are presented. The directivity of LTSA elements is predicted correctly by taking the cross polarized pattern into account. A moment method program predicts radiation patterns for air LTSAs with excellent agreement with experimental data. A moment method program was also developed for the task LTSA Array Modeling. Computations performed with this program are in excellent agreement with published results for dipole and monopole arrays, and with waveguide simulator experiments, for more complicated structures. Empirical modeling of LTSA arrays demonstrated that the maximum theoretical element gain can be obtained. Formulations were also developed for calculating the aperture efficiency of LTSA arrays used in reflector systems. It was shown that LTSA arrays used in multibeam systems have a considerable advantage in terms of higher packing density, compared with waveguide feeds. Conversion loss of 10 dB was demonstrated at 35 GHz

Rethinking the scale, structure & scope of U.S. energy institutions

This essay notes some of the key institutions created in the twentieth century for the purpose of delivering energy in North America. Those institutions are being challenged by a combination of stresses in three interconnected areas: reliability, economics, and environmental sustainability. The essay argues that these three stresses create an “energy trilemma” requiring institutional reform. We suggest that new and modi½ed institutions can best be understood if we evaluate them along three dimensions: institutional scale, structure, and scope. We consider real-world examples of recent institutions in light of each of these dimensions and note both successes and concerns that those factors illuminate. We conclude by noting that some institutional changes will be organic and unplanned; but many others, including responses to climate change, will bene½t from conscious attention to scale, structure, and scope by those engaged in designing and building the energy institutions needed in the twenty-½rst century

Carrion Beetles (Coleoptera: Silphidae) of Wisconsin

The first comprehensive faunal survey of the carrion beetles (Coleoptera: Silphidae) of Wisconsin is presented. Six genera and 14 species are recorded from the state, including a new state record, Heterosilpha ramosa (Say). Nicrophorus americanus Olivier was not recovered during this study. An annotated checklist includes species-specific geographical and temporal distributions, remarks on foods and habitat, and counties of specimen collections for each species

Quantum communication via a continuously monitored dual spin chain

We analyze a recent protocol for the transmission of quantum states via a dual spin chain [Burgarth and Bose, Phys. Rev. A 71, 052315 (2005)] under the constraint that the receiver's measurement strength is finite. That is, we consider the channel where the ideal, instantaneous and complete von Neumann measurements are replaced with a more realistic continuous measurement. We show that for optimal performance the measurement strength must be "tuned" to the channel spin-spin coupling, and once this is done, one is able to achieve a similar transmission rate to that obtained with ideal measurements. The spin chain protocol thus remains effective under measurement constraints.Comment: 5 pages, revtex 4, 3 eps figure

X ray sensitive area detection device

A radiation sensitive area detection device is disclosed which comprises a phosphor-containing film capable of receiving and storing an image formed by a pattern of incoming x rays, UV, or other radiation falling on the film. The device is capable of fluorescing in response to stimulation by a light source in a manner directly proportional to the stored radiation pattern. The device includes: (1) a light source capable of projecting light or other appropriate electromagnetic wave on the film so as to cause it to fluoresce; (2) a means to focus the fluoresced light coming from the phosphor-containing film after light stimulation; and (3) at least one charged coupled detector or other detecting element capable of receiving and digitizing the pattern of fluoresced light coming from the phosphor-containing film. The device will be able to generate superior x ray images of high resolution from a crystal or other sample and will be particularly advantageous in that instantaneous near-real-time images of rapidly deteriorating samples can be obtained. Furthermore, the device can be made compact and sturdy, thus capable of carrying out x ray or other radiation imaging under a variety of conditions, including those experienced in space

Experimental Hamiltonian Identification for Qubits subject to Multiple Independent Control Mechanisms

We consider a qubit subject to various independent control mechanisms and present a general strategy to identify both the internal Hamiltonian and the interaction Hamiltonian for each control mechanism, relying only on a single, fixed readout process such as $\sigma_z$ measurements.Comment: submitted to Proceedings of the QCMC04 (4 pages RevTeX, 5 figures
