Nicotinic acetylcholine (ACh) receptors (nAChRs) are ligand-gated ion channels which mediate fast cholinergic synaptic transmission in insect and vertebrate nervous systems. The nAChR agonist-binding site is present at the interface of adjacent subunits and is formed by loops A-C present in alpha subunits together with loops D-F present in either non-alpha(More)
Eighty-seven isolates of Colletotrichum graminicola, mostly from Agrostis palustris, were collected in grass fields, most of which were in Ontario, Canada. Specific primers were designed to amplify the mating-type (MAT) genes and, among 35 isolates tested, all yielded a band of the expected size for MAT2. For six isolates, the MAT2 PCR products were(More)
This paper studies the distributed caching managements for the current flourish of the streaming applications in multihop wireless networks. Many caching managements to date use randomized network coding approach, which provides an elegant solution for ubiquitous data accesses in such systems. However, the encoding, essentially a combination operation,(More)
Portions of the mating type genes from Ophiosphaerella korrae (a pathogenic fungus of grasses, were examined by PCR (polymer-ase chain reaction). For nine isolates of O. korrae from North America, both mating type genes were amplified, demonstrating that both MAT idiomorphs are detectable in this homothallic ascomycete. Amplified fragments from three(More)
—Existing routing protocols for Wireless Mesh Networks (WMNs) are generally optimized with statistical link measures, while not addressing on the intrinsic uncertainty of wireless links. We show evidence that, with the transient link uncertainties at PHY and MAC layers, a pseudo-deterministic routing protocol that relies on average or historic statistics(More)
The choice of features or attributes used to represent patterns in the synthesis of pattern classiiers using machine learning algorithms has a strong impact on the accuracy of the classiier, the number of examples needed to attain a given classiication accuracy on test data, the cost of classiication, and the com-prehensibility of the learned classiier.(More)
