On the Images of Braid Group Representations Coming from Braided Fusion Categories

Braided fusion categories are algebraic structures with strong ties to the representation theory of finite groups, Hopf algebras, and quantum groups. These structures also have strong connections with braid groups and low-dimensional topology. Recently, braid group representations coming from braided fusion categories have become a topic of interest in areas of condensed matter physics and topological quantum computation. Particularly interesting are the properties of the images of these representations. Calculations to determine the finiteness of these images have been performed for a few cases. A class of braided fusion categories coming from finite groups (group-theoretical) has been shown to yield finite images. We show that the images of braid group representations coming from the larger class of weakly group-theoretical braided fusion categories are also finite. We then compute the images of the pure braid groups for some specific representations

University of Missouri--Columbia 2009.In the midst of this genomics era, major plant genome databases are collecting massive amounts of heterogeneous information, including sequence data, gene product information, as well as images and descriptions of mutant phenotypes. While basic browsing and search capabilities are available to allow researchers to query and peruse the names and attributes of stored data, advanced search mechanisms that can take advantage of textual descriptions of various types of stored data are nonexistent. Furthermore, though much time and effort have been afforded to the development of plant-related ontologies, the knowledge embedded in these ontologies remains largely unused in available plant search mechanisms. Addressing both of these issues, we have developed a unique search engine for the phenotypes in MaizeGDB. This advanced search mechanism exploits the content and structure of available domain ontologies for the purposes of query enrichment, with currently both the Plant Ontology and Gene Ontology being utilized. The search engine also has the flexibility to integrate various text description sources to aid the user in retrieving desired phenotype information. This framework can be generalized to any domain with a domain-specific ontology or to sets of text sources that are heterogeneous and interconnected.Includes bibliographical references

Overstory density and its effect on oak regeneration abundance and oak understory height growth in the Missouri Ozark Highlands

The entire dissertation/thesis text is included in the research.pdf file; the official abstract appears in the short.pdf file (which also appears in the research.pdf); a non-technical general description, or public abstract, appears in the public.pdf file.Title from title screen of research.pdf file (viewed on August 12, 2009)Thesis (M.S.) University of Missouri-Columbia 2008.This study examined how overstory density affects regeneration abundance and understory height growth in the Missouri Ozark Highlands. Data were collected on three different treatment types, no harvest management, uneven-aged management, and even-aged management. The probability of obtaining regeneration that met height and abundance thresholds decreased with increasing overstory density for white oaks, red oaks, and non-oaks. A relatively small increase in overstory basal area significantly decreased success probabilities for the red oaks, white oaks and non-oaks. For understory growth, the probability of obtaining height growth thresholds for red oaks, white oaks, and non-oak species decreased with increasing overstory density. Height growth of red oaks, white oaks, and non-oaks were not statistically different when overstory density was increased above the clearcut level. Results suggest that regulating overstory density is necessary to control regeneration abundance and understory height growth. Reducing overstory density below the B-level on the Gingrich diagram (1967) may be necessary to allow sufficient light to penetrate the forest floor for adequate regeneration abundance and understory height growth.Includes bibliographical reference

Letter from the Editors

[Excerpt] The Editorial Team is proud to release this 2016 14th Annual Volume of the Cornell Real Estate Review. This year’s issue explores a wide range of topics, including the deployment of new technologies in multifamily properties, the effects of autonomous vehicles on real estate, and the continued ramifications of the housing crisis through the legal tactics of certain mortgage lenders. Also included, a recent repositioning project– the unique turnaround of a former casino hotel property in Reno, Nevada. Furthermore, this release includes a discussion of value-added multifamily investment strategy, an analysis of the impact of rapid transit on the residential market in Hudson County, New Jersey, and a summary of federal affordable housing incentive programs in the United States. This year’s Pathways features an interview with Toll Brothers Division President Karl Mistry (Baker ’04), and the Baker Viewpoint piece explores the concept of curtailment mortgages
