Our knowl edge about plant cell wall bi ol ogy has grown sig nif i cantly from the six ties of the 20th cen tury, when pro teins were iden ti fied by their en zy matic ac tiv ity i...

For a nonsymm etri c threshold network equippe d with an asynchronous dynamics, we show that if the product of weights in any cycle of units is nonnegative, then each tr ajectory converges to a stable state with probability one. We also show that such networks have a natural feed-forward layer struc ture and stabilit y is achieved in a hierarchical order due to this struct ure. It follows then ...

n a recent paper [l], Van Blade1 discussed in detail the behavior I of fields j . ' and surface charges near singularities of metallic struc$res, such as a hollow circular cylinder, a circulai cone, a thin prolate spheroid, and a uniformly charged segment. At times, the reasoning in [I] leads to conclusions not as definitive as one might wish because of the various approximations introduced, su...

It is a well-known fact that enlargements of the pre-auricular gland and the parotid occur as complications of otitis media. The path of infection is evidently via the lymph or blood channels, and apart from the pain of acute otitis, there is much swelling and pain in front of the ear. If the mandibular joint is involved and in little children the fright of opening the mouth either for swallowi...

Sumo is a formalism for universal segmentation of text Its purpose is to provide a framework for the creation of segmentation applications It is called universal as the formalism itself is independent of the language of the documents to process and independent of the levels of seg mentation e g words sentences paragraphs morphemes considered by the target applica tion This framework relies on a...

This report explores the direct counting of "hair-like" struc-tures specific for Gram-positive bacteria. Indications show that these structures are intact after removal from the cell and are sufficiently different from species to species of bacteria to give an indication of bacteria type if not actual identification. Their detection would represent a new approach to bacteria detection and ident...

Inference for cross sectional models using longitudinal data can be drawn with independence estimating equations Liang and Zeger Many studies su er from missing data Robins and coworkers proposed to use weighted estimating equations WEE in estimating the mean struc ture if missing data are present in dependent variables In this paper the WEE are compared with complete case analyses for binary r...
