Improving estimates of the number of fake leptons and other mis-reconstructed objects in hadron collider events: BoB's your UNCLE. (Previously "The Matrix Method Reloaded")

We consider current and alternative approaches to setting limits on new physics signals having backgrounds from misidentified objects; for example jets misidentified as leptons, b-jets or photons. Many ATLAS and CMS analyses have used a heuristic matrix method for estimating the background contribution from such sources. We demonstrate that the matrix method suffers from statistical shortcomings that can adversely affect its ability to set robust limits. A rigorous alternative method is discussed, and is seen to produce fake rate estimates and limits with better qualities, but is found to be too costly to use. Having investigated the nature of the approximations used to derive the matrix method, we propose a third strategy that is seen to marry the speed of the matrix method to the performance and physicality of the more rigorous approach.Comment: v1 :11 pages, 5 figures. v2: title change requested by referee, and other corrections/clarifications found during review. v3: final tweaks suggested during review + move from revtex to jhep styl

Nonadiabatic Electronic Interactions In The Ion-Pair States Of NelCl

Nonadiabatic interactions in the NeIC1 van der Waals complex have been explored in the lowest energy triad of IC1 ion-pair states (approximately 39 000 cm-1). Dispersed fluorescence measurements reveal emission characteristic of multiple ion-pair electronic states, with the relative contributions from the E(O+ ), beta(1), and D\u27(2) states changing with the initial IC1 vibrational excitation (v(IC1)). Emission directly from NeIC1 (v(IC1) = O) complexes indicates that the initially prepared NeIC1 levels have mixed electronic character and that the IC1 electronic parentage changes with the initial van der Waals vibrational level selected. NeIC1 complexes prepared with 1-4 quanta of IC1 stretch undergo rapid vibrational predissociation with a strong propensity for DELTA-V(IC1) = - 1 relaxation. The electronic state(s) populated in the IC1 fragments differ from the mixed electronic character of the initially prepared level, demonstrating that vibrational predissociation is accompanied by nonadiabatic electronic state changing processes. The observed final state selectivity may be attributed to the relative strength of the nonadiabatic couplings between the initial NeIC1 bound state and the final IC1 states or a momentum gap rationale based on the overlap between the NeIC1 bound state wave function and the highly oscillatory continuum wave function of the separating fragments

Molecular Marker Linkage Mapping in Southern Pine (Longleaf Pine and Slash Pine).

The goal of this work was to develop molecular markers for use in a backcross breeding program to speed the introgression of genes influencing rapid early height growth (EHG) from slash pine (Pinus elliottii Engelm. var. elliottii) into longleaf pine (Pinus palustris Mill.). The efficacy of molecular markers for genetic mapping in the Pinaceae was determined in segregating haploid and diploid populations. Initial screening for genetic polymorphisms was conducted using the random amplified polymorphic DNA (RAPD) technique. Using DNAs obtained from haploid megagametophytes, a RAPD-based genetic map for longleaf pine clone 3-356 (16 linkage groups and 6 pairs (133 markers) covering 1,635 cM) was constructed. Concern regarding the efficacy of RAPD data lead to a series of computer simulations investigating the effects of missing and mis-scored data on linkage group construction. Given the parameters investigated, levels as high as 15% missing data and 2% mis-scored data still provided accurate low-to medium-density map construction. Individual parental maps were constructed with F\sb1 progeny from a slash pine H-28 (X) x longleaf pine 3-356 (X) cross. The longleaf pine 3-356 map consisted of 18 groups and 3 pairs (122 markers) covering 1367.5 cM, and the slash pine H-28 map 13 groups and 6 pairs (91 markers) covering 952.9 cM. Orders and distances of loci in common between the two maps constructed for longleaf pine 3-356 were compared. Orders were found to be conserved for those groups containing three or more loci. However, genetic distance estimates varied considerably, but not in any systematic manner. RAPD and allozyme loci identified as being heterozygous in both parents were utilized to combine the parent-specific maps constructed for the slash pine x longleaf pine cross. Five RAPD loci and one allozyme locus suggested homology between the otherwise parent-specific linkage groups. Substantial phenotypic variation for EHG was observed in the F\sb1 population, therefore the parent-specific markers and maps were used to localize putative EHG QTL. Using simultaneous marker models (multiple regression), marker loci were found to be significantly associated with QTL influencing hypocotyl length, total height, brown spot resistance and root collar diameter

The Heroes of Byron: A Study of their Origin, Development, and Meaning in the Poetry of George Gordon, Lord Byron

Lord Byron was very much concerned with the problems of immortality and fame. Perhaps his greatest single theme in poetry is human greatness. An especial aspect of human greatness, namely of heroes in spirit and in action, is, of course, one of the most permanent and best known features of Byron\u27s poetry, the creation of the Byronic hero being one of the poet\u27s most outstanding contribu- tions to world literature. This study is concerned with all of the heroes Lord Byron created. It is to be a study of their origin, development, and meaning in the poetry of Byron. Lord Byron published his first poetry, Hours of Idleness, which included some thirty-nine poems of varying length and quality, mostly written in the style of Alexander Pope and many of them employing the heroic couplet, in 1807. Byron was nineteen
