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

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

The mitochondrial ribosome from Locusta migratoria

Mitochondrial ribosomes from locust thorax muscles have been identified recently in our labo-ratory by specific labelling of the adhering nascent peptide chains and have been isolated from mito
