Errata: Second in a Seemingly Endless Series

Amid our reflections upon the wisdom of the Association\u27s founders who gave this office a one-year term, and amid recollections of that rare whiff of summer breeze that swept across our Richmond dining room one weekend and blew all the pasted-up pages on the floor just before they were given their numbers, we apologize again to contributors and readers and note a few of the significant transpositions and other unplanned features of our May Newsletter

Reflections on the AED 20th Anniversary

We were all younger then, and at thirty I guess I was younger and I certainly had done far less than most of the people gathered in a hotel room in St. Louis to establish the Association for Documentary Editing. I\u27m quite certain that I didn\u27t say anything- for although I was strongly committed to documentary editing, the Southern Historical Association was meeting at the now-demolished hotel near Forest Park, and on the previous afternoon I had presented my first paper to a professional historical meeting. Linda Grant DePauw had commented, Merrill Peterson had chaired, and I was grateful not only to have survived but to have won a few words of praise. At the initial meeting of the ADE, I found myself once again in the company of important historians whose names I held in awe, as well as terribly impressive literary scholars talking of CSE standards and vetting and other wondrous things

The Power of Positivist Babble Or, Two Anecdotes Declining Toward a Conclusion: Review of \u3ci\u3eLiterary & Historical Editing\u3c/i\u3e. Edited and with introductions by George L. Vogt and John Bush Jones.

The seven components of Literary & Historical Editing are three introductory pieces (two by the editors and the third, a survey of modern literary and historical editions, by James Thorpe), essays by George C. Rogers, Jr., and G. Thomas Tanselle on textual editing, and two discussions of annotation. Martin C. Battestin\u27s suggestions about literary annotation-which have also been published in volume 34 of Studies in Bibliography (1981)struck me as sensible and clear, especially if one may accept at face value his disclaimers: that he is not trying to do for the literary annotator what Greg has done for the textual editor,» and that there can be no single rationale of literary annotation that will prove universally practicable and appropriate (p. 59). Charles T. Cullen\u27s survey of annotation practices in modern editions of historical documents is, in my estimation, our first substantial published discussion of the question. Feigning surprise that even [editors] do not agree on a set of principles of annotation (p. 81), Cullen himself eschews any definition of rarefied principles and advocates sound editorial judgment, moderation, and a clear focus on the subject of the publication (p. 91). By reporting what historical editors 5 have thought they were doing during the past thirty years, Cullen also places in high relief a few of the confused assumptions and professional insecurities that marked historical editing during the third quarter of the twentieth century (and that still limit the working vocabulary of a rising generation of historians). If I read them correctly, both Battestin and Cullen doubt the existence or desirability of any theory of annotation applicable to all cases. Clearly, annotation is among the applied rather than the pure sciences

PEDFLOW: development of an autonomous agent model of pedestrian flow.

The paper discusses the need for an autonomous agent approach for the modeling of pedestrians in urbanenvironments and places PEDFLOW in the context of existing models. PEDFLOW is a microscopic modelof pedestrians’ movement, where each pedestrian is represented as an agent capable of making its owndecisions based upon a part of the observable scene local to that pedestrian. The model, implemented inJava, provides a framework where agents are visualised as squares in a grid and movement is modelled as achange of grid position with a delay that characterises the speed of the agent. A single rule set is utilisedthat is made specific to each agent by the incorporation of parameters characterising ‘types’ of pedestrians.The rules originate from computer aided analysis of video footage and are transformed into a form that canbe efficiently processed by the agent. By adding tools to extract measures of pedestrian flow, thePEDFLOW model will be made useful to urban planners to evaluate infrastructural changes intended topromote walking in the urban environment

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Search for direct stau production in events with two hadronic tau-leptons in root s=13 TeV pp collisions with the ATLAS detector

A search for the direct production of the supersymmetric partners ofτ-leptons (staus) in final stateswith two hadronically decayingτ-leptons is presented. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of139fb−1, recorded with the ATLAS detector at the LargeHadron Collider at a center-of-mass energy of 13 TeV. No significant deviation from the expected StandardModel background is observed. Limits are derived in scenarios of direct production of stau pairs with eachstau decaying into the stable lightest neutralino and oneτ-lepton in simplified models where the two staumass eigenstates are degenerate. Stau masses from 120 GeV to 390 GeV are excluded at 95% confidencelevel for a massless lightest neutralino

Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s=13 TeV pp collisions with the ATLAS detector

A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of √s=13  TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139  fb−1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015–2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV

Measurement of the View the tt production cross-section using eμ events with b-tagged jets in pp collisions at √s = 13 TeV with the ATLAS detector

This paper describes a measurement of the inclusive top quark pair production cross-section (σtt¯) with a data sample of 3.2 fb−1 of proton–proton collisions at a centre-of-mass energy of √s = 13 TeV, collected in 2015 by the ATLAS detector at the LHC. This measurement uses events with an opposite-charge electron–muon pair in the final state. Jets containing b-quarks are tagged using an algorithm based on track impact parameters and reconstructed secondary vertices. The numbers of events with exactly one and exactly two b-tagged jets are counted and used to determine simultaneously σtt¯ and the efficiency to reconstruct and b-tag a jet from a top quark decay, thereby minimising the associated systematic uncertainties. The cross-section is measured to be: σtt¯ = 818 ± 8 (stat) ± 27 (syst) ± 19 (lumi) ± 12 (beam) pb, where the four uncertainties arise from data statistics, experimental and theoretical systematic effects, the integrated luminosity and the LHC beam energy, giving a total relative uncertainty of 4.4%. The result is consistent with theoretical QCD calculations at next-to-next-to-leading order. A fiducial measurement corresponding to the experimental acceptance of the leptons is also presented

Search for High-Mass Resonances Decaying to τν in pp Collisions at √s=13 TeV with the ATLAS Detector

A search for high-mass resonances decaying to τν using proton-proton collisions at √s=13 TeV produced by the Large Hadron Collider is presented. Only τ-lepton decays with hadrons in the final state are considered. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 36.1 fb−1. No statistically significant excess above the standard model expectation is observed; model-independent upper limits are set on the visible τν production cross section. Heavy W′ bosons with masses less than 3.7 TeV in the sequential standard model and masses less than 2.2–3.8 TeV depending on the coupling in the nonuniversal G(221) model are excluded at the 95% credibility level
