Metaphor and Metanoia: Linguistic Transfer and Cognitive Transformation in British and Irish Modernism
This dissertation contributes to the critical expansions that Douglas Mao and Rebecca L. Walkowitz identify as New Modernist Studies. This expansion is temporal, spatial, and vertical. I engage with the effects Modernist texts have “above” the page: lived experience. I examine the structural similarity of linguistic metaphor and the mind as considered by cognitive scientists. Identifying the human mind as linguistic and language as an artifact of the human mind, my research extrapolates upon what I call the “psycho-ecology” of reading, a self-representational knot between text and mind that constitutes lived experience. Far from being an abstraction, psycho-ecology is concrete: atypical textual engagement is equated with a transformation in perception. The prologue traces a lineage between Modernism, phenomenology, and the cognitive sciences. The first chapter considers the relationship between two narrative levels in Oscar Wilde’s novel The Picture of Dorian Gray (1890). The second chapter considers temporal experimentation in Virginia Woolf’s novel To the Lighthouse (1927) in relation to Martin Heidegger’s formulation of being as that which discloses our experience with language as temporal and finite. The third chapter examines the “sentimental information” of James Joyce’s Finnegans Wake (1939) from a phenomenological approach to information theory. The final chapter analyzes Samuel Beckett’s Endgame (1957) as a zero-player game that discloses the limits of agency in psycho-ecology. The dissertation follows a trajectory beginning with the intimacy a reader has with alphanumeric text towards the increasing experience of illiteracy when encountering new languages such as digital code
Primary Numbers Database for ATLAS Detector Description Parameters
We present the design and the status of the database for detector description
parameters in ATLAS experiment. The ATLAS Primary Numbers are the parameters
defining the detector geometry and digitization in simulations, as well as
certain reconstruction parameters. Since the detailed ATLAS detector
description needs more than 10,000 such parameters, a preferred solution is to
have a single verified source for all these data. The database stores the data
dictionary for each parameter collection object, providing schema evolution
support for object-based retrieval of parameters. The same Primary Numbers are
served to many different clients accessing the database: the ATLAS software
framework Athena, the Geant3 heritage framework Atlsim, the Geant4 developers
framework FADS/Goofy, the generator of XML output for detector description, and
several end-user clients for interactive data navigation, including web-based
browsers and ROOT. The choice of the MySQL database product for the
implementation provides additional benefits: the Primary Numbers database can
be used on the developers laptop when disconnected (using the MySQL embedded
server technology), with data being updated when the laptop is connected (using
the MySQL database replication).Comment: Talk from the 2003 Computing in High Energy and Nuclear Physics

New science on the Open Science Grid
The Open Science Grid (OSG) includes work to enable new science, new scientists, and new modalities in support of computationally based research. There are frequently significant sociological and organizational changes required in transformation from the existing to the new. OSG leverages its deliverables to the large-scale physics experiment member communities to benefit new communities at all scales through activities in education, engagement, and the distributed facility. This paper gives both a brief general description and specific examples of new science enabled on the OSG. More information is available at the OSG web site: www.opensciencegrid.org

An intelligent Data Delivery Service for and beyond the ATLAS experiment
The intelligent Data Delivery Service (iDDS) has been developed to cope with
the huge increase of computing and storage resource usage in the coming LHC
data taking. iDDS has been designed to intelligently orchestrate workflow and
data management systems, decoupling data pre-processing, delivery, and main
processing in various workflows. It is an experiment-agnostic service around a
workflow-oriented structure to work with existing and emerging use cases in
ATLAS and other experiments. Here we will present the motivation for iDDS, its
design schema and architecture, use cases and current status, and plans for the
future.Comment: 6 pages, 5 figure
GEANT4 : a simulation toolkit
Abstract Geant4 is a toolkit for simulating the passage of particles through matter. It includes a complete range of functionality including tracking, geometry, physics models and hits. The physics processes offered cover a comprehensive range, including electromagnetic, hadronic and optical processes, a large set of long-lived particles, materials and elements, over a wide energy range starting, in some cases, from 250 eV and extending in others to the TeV energy range. It has been designed and constructed to expose the physics models utilised, to handle complex geometries, and to enable its easy adaptation for optimal use in different sets of applications. The toolkit is the result of a worldwide collaboration of physicists and software engineers. It has been created exploiting software engineering and object-oriented technology and implemented in the C++ programming language. It has been used in applications in particle physics, nuclear physics, accelerator design, space engineering and medical physics. PACS: 07.05.Tp; 13; 2
Multiplicity distribution and spectra of negatively charged hadrons in Au+Au collisions at sqrt(s_nn) = 130 GeV
The minimum bias multiplicity distribution and the transverse momentum and
pseudorapidity distributions for central collisions have been measured for
negative hadrons (h-) in Au+Au interactions at sqrt(s_nn) = 130 GeV. The
multiplicity density at midrapidity for the 5% most central interactions is
dNh-/deta|_{eta = 0} = 280 +- 1(stat)+- 20(syst), an increase per participant
of 38% relative to ppbar collisions at the same energy. The mean transverse
momentum is 0.508 +- 0.012 GeV/c and is larger than in central Pb+Pb collisions
at lower energies. The scaling of the h- yield per participant is a strong
function of pt. The pseudorapidity distribution is almost constant within
|eta|<1.Comment: 6 pages, 3 figure
New Science on the Open Science Grid
The Open Science Grid (OSG) includes work to enable new science, new
scientists, and new modalities in support of computationally based research.
There are frequently significant sociological and organizational changes
required in transformation from the existing to the new. OSG leverages its
deliverables to the large scale physics experiment member communities to
benefit new communities at all scales through activities in education,
engagement and the distributed facility. As a partner to the poster and
tutorial at SciDAC 2008, this paper gives both a brief general description and
some specific examples of new science enabled on the OSG. More information is

Jet energy measurement with the ATLAS detector in proton-proton collisions at root s=7 TeV
The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy of √s = 7TeV corresponding to an integrated luminosity of 38 pb-1. Jets are reconstructed with the anti-kt algorithm with distance parameters R=0. 4 or R=0. 6. Jet energy and angle corrections are determined from Monte Carlo simulations to calibrate jets with transverse momenta pT≥20 GeV and pseudorapidities {pipe}η{pipe}<4. 5. The jet energy systematic uncertainty is estimated using the single isolated hadron response measured in situ and in test-beams, exploiting the transverse momentum balance between central and forward jets in events with dijet topologies and studying systematic variations in Monte Carlo simulations. The jet energy uncertainty is less than 2. 5 % in the central calorimeter region ({pipe}η{pipe}<0. 8) for jets with 60≤pT<800 GeV, and is maximally 14 % for pT<30 GeV in the most forward region 3. 2≤{pipe}η{pipe}<4. 5. The jet energy is validated for jet transverse momenta up to 1 TeV to the level of a few percent using several in situ techniques by comparing a well-known reference such as the recoiling photon pT, the sum of the transverse momenta of tracks associated to the jet, or a system of low-pT jets recoiling against a high-pT jet. More sophisticated jet calibration schemes are presented based on calorimeter cell energy density weighting or hadronic properties of jets, aiming for an improved jet energy resolution and a reduced flavour dependence of the jet response. The systematic uncertainty of the jet energy determined from a combination of in situ techniques is consistent with the one derived from single hadron response measurements over a wide kinematic range. The nominal corrections and uncertainties are derived for isolated jets in an inclusive sample of high-pT jets. Special cases such as event topologies with close-by jets, or selections of samples with an enhanced content of jets originating from light quarks, heavy quarks or gluons are also discussed and the corresponding uncertainties are determined. © 2013 CERN for the benefit of the ATLAS collaboration
