Training for digital preservation in the context of the European project PLANETS

This paper outlines a training programme jointly developed and organised by the Humanities Advanced Technology and Information Institute (‘HATII’) at the University of Glasgow and the British Library, in collaboration with a number of European partner institutions, on behalf of the Preservation and Long Term Access Through Networked Services (‘Planets’) project. It describes the background to the programme and the series of events which took place during the final year of the project, focussing on the feedback received from the participants, the lessons learned from the implementation of the events, and the perceived long-term impact of the programme on future digital preservation training activities

Rotational CARS application to simultaneous and multiple-point temperature and concentration determination in a turbulent flow

Coherent anti-Stokes Raman scattering (CARS) from the pure rotational Raman lines of N2 is employed to measure the instantaneous (approximately 10 ns) rotational temperature of N2 gas at room temperature and below with good spatial resolution (0.2 x 0.2 x 3.0 cu mm). A broad bandwidth dye laser is used to obtain the entire rotational spectrum from a single laser pulse; the CARS signal is then dispersed by a spectrograph and recorded on an optical multichannel analyzer. A best fit temperature is found in several seconds with the aid of a computer for each experimental spectrum by a least squares comparison with calculated spectra. The model used to calculate the theoretical spectra incorporates the temperature and pressure dependence of the pressure-broadened rotational Raman lines, includes the nonresonant background susceptibility, and assumes that the pump laser has a finite linewidth. Temperatures are fit to experimental spectra recorded over the temperature range of 135 to 296 K, and over the pressure range of .13 to 15.3 atm

Search for New Physics Using QUAERO: A General Interface to D0 Event Data

We describe QUAERO, a method that (i) enables the automatic optimization of searches for physics beyond the standard model, and (ii) provides a mechanism for making high energy collider data generally available. We apply QUAERO to searches for standard model WW, ZZ , and tt̅ production, to searches for these objects produced through a new heavy resonance, and to the first direct search for W′→ WZ. Through this interface, we make three data sets collected by the D0 experiment at √s =1.8 TeV publicly available

Multiple jet production at low transverse energies in \u3ci\u3epp̅\u3c/i\u3e collisions at √\u3ci\u3es\u3c/i\u3e = 1.8 TeV

We present data on multiple production of jets with transverse energies near 20 GeV in pp̅ collisions at √s =1.8 TeV. QCD calculations in the parton-shower approximation of PYTHIA and HERWIG and the next-to-leading order approximation of JETRAD are compared to the data for one, two, three, and four jet inclusive production. Transverse energy spectra and multiple jet angular and summed transverse-energy distributions are adequately described by the shower approximation while next-to-leading order calculations describe the data poorly

Modelling 3D magnetic networks in a realistic solar atmosphere

This is the final version. Available from OUP via the DOI in this recordThe magnetic network extending from the photosphere (solar radius ≃ R☉ ) to lower corona (R☉ + 10Mm) plays an important role in the heating mechanisms of the solar atmosphere. Here we further develop the models with realistic open magnetic flux tubes of the authors in order to model more complicated configurations. Closed magnetic loops, and combinations of closed and open magnetic flux tubes are modelled. These are embedded within a stratified atmosphere, derived from observationally motivated semi-empirical and data-driven models subject to solar gravity and capable of spanning from the photosphere up into the chromosphere and lower corona. Constructing a magnetic field comprising self-similar magnetic flux tubes, an analytic solution for the kinetic pressure and plasma density is derived. Combining flux tubes of opposite polarity it is possible to create a steady background magnetic field configuration modelling a solar atmosphere exhibiting realistic stratification. The result can be applied to SOHO/MDI and SDO/HMI and other magnetograms from the solar surface, upon which photospheric motions can be simulated to explore the mechanism of energy transport. We demonstrate this powerful and versatile method with an application to Helioseismic and Magnetic Imager data.Academy of FinlandScience and Technology Facilities Council (STFC

Search for Pair Production of Light Scalar Top Quarks in \u3ci\u3epp̅\u3c/i\u3e Collisions at √\u3ci\u3es\u3c/i\u3e = 1.8 TeV

Using 85.2 ± 3.6 pb1 of pp̅ collisions collected at √s = 1.8 TeV with the D0 detector at Fermilab’s Tevatron Collider, we present the results of a search for direct pair production of scalar top quarks (t̃), the supersymmetric partners of the top quark. We examined events containing two or more jets and missing transverse energy, the signature of light scalar top quark decays to charm quarks and neutralinos. After selections, we observe 27 events while expecting 31.1 ± 6.4 events from known standard model processes. Comparing these results to next-to-leading-order production cross sections, we exclude a significant region of t̃ and neutralino phase space. In particular, we exclude the t̃ mass mt̃ \u3c 122 GeV/c2 for a neutralino mass of 45 GeV/c2

Measurement of the \u3ci\u3eWW\u3c/i\u3e Production Cross Section in \u3ci\u3epp̅\u3c/i\u3e Collisions at √\u3ci\u3es\u3c/i\u3e = 1.96 TeV

We present a measurement of the W boson pair-production cross section in pp̅ collisions at a center-of- mass energy of √s = 1.96 TeV. The data, collected with the Run II D0 detector at Fermilab, correspond to an integrated luminosity of 224–252 pb-1 depending on the final state (ℯℯ, ℯμ, or μμ). We observe 25 candidates with a background expectation of 8.1 ± 0.6(stat) ± 0.6(syst) ± 0.5(lum) events. The probability for an upward fluctuation of the background to produce the observed signal is 2.3 x 10-7, equivalent to 5.2 standard deviations. The measurement yields a cross section of 13.8-3.8+4.3 (stat)-0.9+1.2 (syst) ± 0.9(lum) pb, in agreement with predictions from the standard model
