The extracellular matrix is constructed beyond the plasma membrane, challenging mechanisms for its control by the cell. In plants, the cell wall is highly ordered, with cellulose microfibrils aligned coherently over a scale spanning hundreds of cells. To a considerable extent, deploying aligned microfibrils determines mechanical properties of the cell wall, including strength and compliance. Ce...

In this paper, we introduce the interested reader to homological mirror symmetry. After recalling a little background knowledge, we tackle the simplest cases of homological mirror symmetry: curves of genus zero and one. We close by outlining the current state of the field and mentioning what homological mirror symmetry has to say about other aspects of mirror symmetry.

One of the most mysterious fish of the western Atlantic is the European eel. Its range is vast: adults spend the bulk of their life in freshwater systems from Iceland to Morocco. And, indeed, the species has supported one of the biggest fisheries in Europe, employing up to 25,000 people at its height. But, as with many other commercial species, stocks are now in dangerous decline. The number of...

In this paper, we introduce the concept of meet precontinuous posets, a generalization of meet continuous lattices to posets. The main results are: (1) A poset P is meet precontinuous iff its normal completion is a meet continuous lattice iff a certain system γ(P ) which is, in the case of complete lattices, the lattice of all Scott-closed sets is a complete Heyting algebra; (2) A poset P is pr...

The web has transformed the way scientists search for information, but its potential as a tool for scientific collaboration is still largely unrealized. The BIONET newsgroups prove that even 1960s technology can support some kind of intelligent discussion, and IRC (Internet Relay Chat) shows that large-scale, realtime communication is also possible across the net, but for serious use and constr...

UvrD is a superfamily I DNA helicase with well documented roles in excision repair and methyldirected mismatch repair (MMR) in addition to poorly understood roles in replication and recombination. The MutL protein is a homodimeric DNAstimulated ATPase that plays a central role in MMR in Escherichia coli. This protein has been characterized as the master regulator of mismatch repair since it int...

Simulcast Technique can be used to diminish handoff rate and share resources among multiple relays in MMR system. Using dynamic grouping, simulcast technique can also rearrange traffic load. In this paper, we analyze group handoff generated by dynamic grouping in MMR system. Performance is evaluated in view of blocking and handoff call dropping probability.

Text summarization is an interesting area for researchers to develop new techniques to provide human like summaries for vast amounts of information. Summarization techniques tend to focus on providing accurate representation of content; and often the tone of the content is ignored. Tone of the content sets a baseline for how a reader perceives the content. As such being able to generate summary...

This paper develops and studies techniques for recovery from transmission errors that occur in facsimile images compressed with the Group 3, Extended 2 Dimensional MMR coding. When an error occurs in an MMR coded bitstream, the bitstream cannot be decoded after the error point, and the decoded image will have nothing after the error position. To prevent losing all information after an error, we...
