Myosides seriehispidus Roelofs : an Asian weevil new to the United States (Coleoptera, Curculionidae)

Myosides seriehispidus Roelofs, a small cryptic broadnosed weevil from Japan, is reported as established in the eastern U.S. since at least 1973. This nocturnal weevil has been collected most often from leaflitter using berleses. The genus and species are redescribed and placement in Kissinger's key to genera of North American weevils is indicated. Dorsal and lateral habitus photographs of this species are included

View-dependent adaptive cloth simulation

This paper describes a method for view-dependent cloth simulation using dynamically adaptive mesh refinement and coarsening. Given a prescribed camera motion, the method adjusts the criteria controlling refinement to account for visibility and apparent size in the camera's view. Objectionable dynamic artifacts are avoided by anticipative refinement and smoothed coarsening. This approach preserves the appearance of detailed cloth throughout the animation while avoiding the wasted effort of simulating details that would not be discernible to the viewer. The computational savings realized by this method increase as scene complexity grows, producing a 2× speed-up for a single character and more than 4× for a small group

On the genus Anchonus Schönherr in Florida (Coleoptera: Curculionidae)

Four species of Anchonus Schonherr occur in Florida: A. flol'idanus Schwarz, A. dul'yi Blatchley, A. blatchleyi Sleeper, and A. suillus (Fabricius), which is recorded from Florida and the continental United States for the first time. The species are distinguished in a key and illustrated. A lectotype is selected for A. floridanus

Recognition of finite exceptional groups of Lie type

Let $q$ be a prime power and let $G$ be an absolutely irreducible subgroup of $GL_d(F)$, where $F$ is a finite field of the same characteristic as \F_q, the field of $q$ elements. Assume that $G \cong G(q)$, a quasisimple group of exceptional Lie type over \F_q which is neither a Suzuki nor a Ree group. We present a Las Vegas algorithm that constructs an isomorphism from $G$ to the standard copy of $G(q)$. If $G \not\cong {}^3 D_4(q)$ with $q$ even, then the algorithm runs in polynomial time, subject to the existence of a discrete log oracle

Minnesota Extension's Mixed Regional/County Model: Greater Impacts Follows Changes in Structure

The Cooperative Extension Service has as its mission helping the public use the research generated at land-grant universities. Since 1914, most states have used a county-based Extension model, with educators in every county and campus-based faculty supporting local educational efforts. This paper outlines why and how the Minnesota Extension Service has replaced this model with a mixed regional/county model, the major features of the new delivery model and the employment consequences of the shift as well as the non-financial advantages of the new model. The structural changes in Minnesota are of interest to Extension stakeholders in other states who are facing similar challenges and want to learn more about the benefits and costs of Minnesota's new model. Within Minnesota the public is beginning to ask a much more important question: What are the impacts of the programs being delivered? Structural change is only valuable if it results in increased programming and greater impacts than would have happened without the change. Although this paper starts to outline some of the changes in program impact, the bulk of that discussion will be reserved for later papers.Teaching/Communication/Extension/Profession,

An anotated list of the Curculionoidea (Coleoptera) of Dominica (excluding Scolytinae and Platypodidae)

Curculionoidea (Coleoptera) of the West Indian island of Dominica are composed of 111 genera and 214 species and subspecies. Some of the species listed are morphospecies, or are known to be undescribed, but all are identified at least to genus. Previously the fauna was recorded as 31 species. Numbers presented herein represent a seven-fold increase in species diversity. Furthermore, the widespread nature of many species demonstrates that the supposedly endemic faunas of many West Indian islands may be based on collecting biases or a lack of people capable of providing species level identifications

Structures Produced by the Collision of Extragalactic Jets with Dense Clouds

We have investigated how several parameters can affect the results of a collision between an extragalactic jet and a dense, intergalactic cloud, through a series of hydrodynamic simulations. Such collisions are often suggested to explain the distorted structures of some radio jets. However, theoretical studies of this mechanism are in conflict over whether it can actually reproduce the observations. The parameters are the Mach number, and the relative densities of the jet and the cloud to the ambient medium. Using a simple prescription we have produced synthetic radio images for comparison with observations. These show that a variety of structures may be produced from simple jet-cloud collisions. We illustrate this with a few examples, and examine the details in one case. In most cases we do not see a clear, sustained deflection. Lighter jets are completely disrupted. The most powerful jets produce a hotspot at the impact which outshines any jet emission and erode the cloud too quickly to develop a deflected arm. It appears that moderate Mach numbers and density contrasts are needed to produce bends in the radio structure. This explains the apparent conflict between theoretical studies, as conclusions were based on different values of these parameters. Shocks are produced in the ambient medium that might plausibly reproduce the observed alignment of the extended emission line regions with the radio axis.Comment: 21 pages, 11 figures.
