Damage to common plumbing materials caused by overwintering Leptoglossus occidentalis (Hemiptera: Coreidae)

The western conifer seed bug, Leptoglossus occidentalis Heidemann (Hemiptera: Coreidae), is a polyphagous pest of coniferous trees (Hedlin et al. 1981). Native to western North America, the seed bug has expanded its range to include eastern Canada and the United States (McPherson et al. 1990; Gall 1992; Marshall 1992; Ridge-O'Connor 2001; Bates 2002) and was recently introduced into Europe (Taylor et al. 2001). Both adults and nymphs feed by inserting their stylets into cones and digesting the contents of developing seeds, and they can cause serious economic losses in high-value seed orchards (Strong et al. 2001; Bates et al. 2002; Bates and Borden 2005

Radiation Induced Damage in GaAs Particle Detectors

The motivation for investigating the use of GaAs as a material for detecting particles in experiments for High Energy Physics (HEP) arose from its perceived resistance to radiation damage. This is a vital requirement for detector materials that are to be used in experiments at future accelerators where the radiation environments would exclude all but the most radiation resistant of detector types.Comment: 5 pages.

Vibronic interactions in the visible and near-infrared spectra of C60− anions

Electron-phonon coupling is an important factor in understanding many properties of the C60 fullerides. However, there has been little success in quantifying the strength of the vibronic coupling in C60 ions, with considerable disagreement between experimental and theoretical results. We will show that neglect of quadratic coupling in previous models for C60- ions results in a significant overestimate of the linear coupling constants. Including quadratic coupling allows a coherent interpretation to be made of earlier experimental and theoretical results which at first sight are incompatible
