TAXONOMIC AND MOLECULAR STUDIES IN CLERIDAE AND HEMIPTERA
Taxonomic changes are made based on checkered beetle (Coleoptera: Cleridae) types of the Natural History Museum, London (BMNH).Lectotypes are designated (and holotypes and paralectotypes recognized) for 44 species of Hydnocerinae, including the type species for Isolemidia, Parmius, Paupris, Allelidea, Blaesiopthalmus and Lemidia, four species of Enoclerus (Clerinae), and 14 species of Cymatodera (Tillinae). Annotations include comments on additional type material, new type locality, previous (type series) locality, and questionable or missing types. Phyllobaenus pallipes(Gorham) and P. rufithorax (Gorham) are synonymized with P. flavifemoratus(Gorham), P. chapini (Wolcott) is synonymized under P. lateralis (Gorham), and P. villosus (Schenkling) is synonymized under P. longus (LeConte), new synonymies.
The first molecular phylogeny of the clerid lineage (Coleoptera: Cleridae, Thanerocleridae) is presented and compared with the two most recent phylogenetic hypotheses of the group. Phylogenetic relationships of checkered beetles wareere inferred from approximately 5,000 nucleotides amplified from four loci (28S, 16S, 12S, COI). A worldwide sample of ~70 genera is included and phylogenies are reconstructed using Bayesian Inference and Maximum Likelihood. The results are not entirely congruent with either of the current classification systems. Three major lineages are recognized. Tillinae are supported as the sister group to all other subfamilies, whereas Thaneroclerinae, Korynetinae sensu latu and a new subfamily formally described here, Epiclininae, new subfamily, form a sister group to Clerinae + Hydnocerinae.
To assess the phylogeny and evolution of Hemiptera, a comprehensive mitogenomic analysis integrating mitogenome-based molecular phylogenetics, fossil-calibrated divergence dating (using BEAST), and ancestral state reconstructions are presented. The 81 sampled mitogenomes represent the most extensive mitogenomic analyses of Hemiptera to date. The putatively primitive “Homoptera” was previously rendered paraphyletic by Heteroptera, whereas the presented results support each group as monophyletic. The results from both diet and habitat ancestral state reconstructions support that 1) Heteroptera (and Homoptera) evolved from a phytophagous ancestor, contrary to the popular hypothesis that the ancestor was predaceous; and 2) family-level radiation of Heteroptera is coincident with the apically-produced labium and the novel hemelytron. It is here proposed these morphological innovations facilitated multiple independent shifts from phytophagy to predation and multiple independent colonizations of aquatic habitats
NLRB Investigatory Records: Disclosure Under the Freedom of Information Act
A fundamental maxim of American political philosophy is the right of each citizen to know what his government is doing. Political leaders have repeatedly assured the American people that government activities are consistent with the ideals of a free and open society. Whatever confidence the American people may have bestowed upon their government as a result of such pronouncements, it was shattered by the revelations of Watergate, and other allegations of illegal activities attributed to several government agencies. Concurrent with these debilitating developments was the less visible bureaucratic obstruction of the Freedom of Information Act of 1966 (FOIA)
Calculating The Beta Coefficient And Required Rate Of Return For Coca-Cola
In this paper, we demonstrate how to compute the required rate of return for Coca-Cola using modern portfolio theory with data downloaded from the internet. We demonstrate how to calculate monthly returns for the index and Coca-Cola and how to use the returns to compute the beta coefficient and the required rate of return using the downloaded data. We show how to validate the data for the market index and the company and how to compute the returns using the dividend and stock split adjusted prices. We demonstrate how to graph the characteristic line for Coca-Cola and use the graph to check that the regression was run correctly. We use Coca-Cola and the S&P 500 Index in this paper, but any company listed on Yahoo! Finance can be used as the example. This paper can be used as the basis of a lecture on intermediate corporate finance or investments to demonstrate the process using a real company
Applying The Teacher Scholar Model In The School Of Business
The teacher-scholar model was proposed in Boyer (1990) and defines four dimensions of scholarship: 1) discovery, 2) integration, 3) application, and 4) teaching. In this paper, we describe the characteristics of scholarship, the theory of the scholarship of teaching, the excellent teacher, and undergraduate research and scholarship. We then show how the teacher-scholar model is applied at one University for annual faculty evaluations. 
Valuing Coca-Cola Using The Free Cash Flow To Equity Valuation Model
In this paper, we provide a detailed example of applying the free cash flow to equity valuation model proposed in Damodaran (2006). Damodaran (2006) argues that the value of a stock is the discounted present value of the future free cash flow to equity discounted at the cost of equity. We combine the free cash flow to equity model with the super-normal growth model to determine the current value of Coca-Cola. At the time of this paper, we determined a value of Coca-Cola at 150 billion
Conservation laws and tachyon potentials in the sliver frame
Conservation laws have provided an elegant and efficient tool to evaluate the
open string field theory interaction vertex, they have been originally
implemented in the case where the string field is expanded in the Virasoro
basis. In this work we derive conservation laws in the case where the string
field is expanded in the so-called sliver -basis. As an
application of these conservation laws derived in the sliver frame, we compute
the open string field action relevant to the tachyon condensation and in order
to present not only an illustration but also an additional information, we
evaluate the action without imposing a gauge choice.Comment: 26 pages, some typos fixed, comments added, references adde
Cryotomography of budding influenza a virus reveals filaments with diverse morphologies that mostly do not bear a genome at their distal end
Influenza viruses exhibit striking variations in particle morphology between strains. Clinical isolates of influenza A virus have been shown to produce long filamentous particles while laboratory-adapted strains are predominantly spherical. However, the role of the filamentous phenotype in the influenza virus infectious cycle remains undetermined. We used cryo-electron tomography to conduct the first three-dimensional study of filamentous virus ultrastructure in particles budding from infected cells. Filaments were often longer than 10 microns and sometimes had bulbous heads at their leading ends, some of which contained tubules we attribute to M1 while none had recognisable ribonucleoprotein (RNP) and hence genome segments. Long filaments that did not have bulbs were infrequently seen to bear an ordered complement of RNPs at their distal ends. Imaging of purified virus also revealed diverse filament morphologies; short rods (bacilliform virions) and longer filaments. Bacilliform virions contained an ordered complement of RNPs while longer filamentous particles were narrower and mostly appeared to lack this feature, but often contained fibrillar material along their entire length. The important ultrastructural differences between these diverse classes of particles raise the possibility of distinct morphogenetic pathways and functions during the infectious process

Application for approval of derived authorized limits for the release of the 190-C trenches and 105-C process water tunnels at the Hanford Site: Volume 2 - source term development
As part of environmental restoration activities at the Hanford Site, Bechtel Hanford, Inc. is conducting a series of evaluations to determine appropriate release conditions for specific facilities following the completion of decontamination and decommissioning projects. The release conditions, with respect to the residual volumetric radioactive contamination, are termed authorized limits. This report presents the summary of the supporting information and the final application for approval of derived authorized limits for the release of the 190-C trenches and the 105-C process water tunnels. This document contains two volumes; this volume (Vol. 2) contains the radiological characterization data, spreadsheet analyses, and radiological source terms
Geometric Tachyon to Universal Open String Tachyon
A system of k Neveu-Schwarz (NS) 5-branes of type II string theory with one
transverse direction compactified on a circle admits various unstable D-brane
systems, - some with geometric instability arising out of being placed at a
point of unstable equilibrium in space and some with the usual open string
tachyonic instability but no geometric instability. We discuss the effect of NS
5-branes on the descent relations among these branes and their physical
interpretation in the T-dual ALF spaces. We argue that if the tachyon potential
controlling these descent relations obeys certain conditions, then in certain
region in the parameter space labelling the background the two types of
unstable branes become identical via a second order phase transition, with the
geometric tachyon in one system getting mapped to the open string tachyon of
the other system. This would provide a geometric description of the tachyonic
instability of the usual non-BPS Dp-brane in ten dimensional flat space-time.Comment: LaTeX file, 30 page
