Microstructure of TiN coatings synthesized by direct pulsed Nd:YAG laser nitriding of titanium: Development of grain size, microstrain, and grain orientation
Pure titanium was irradiated by pulsed Nd:YAG laser irradiation in nitrogen atmosphere. As a result, nitrogen uptake and diffusion occurred and a TiN layer was synthesized at the titanium surface. These TiN coatings were ...
The Integrated Density of States of the Random Graph Laplacian
(Springer US, 2011)
We analyse the density of states of the random graph Laplacian in the percolating regime. A symmetry argument and knowledge of the density of states in the nonpercolating regime allows us to isolate the density of states ...
Submicron focusing of XUV radiation from a laser plasma source using a multilayer Laue lens
The focusing properties of a one-dimensional multilayer Laue lens (MLL) were investigated using monochromatic soft X-ray radiation from a table-top, laser-produced plasma source. The MLL was fabricated by a focused ion ...
Sharp transition from ripple patterns to a flat surface for ion beam erosion of Si with simultaneous co-deposition of iron
We investigate pattern formation on Si by sputter erosion under simultaneous co-deposition of Fe atoms, both at off-normal incidence, as function of the Fe surface coverage. The patterns obtained for 5 keV Xe ion irradiation ...
Differential top-antitop cross-section measurements as a function of observables constructed from final-state particles using pp collisions at s√=7 TeV in the ATLAS detector
Various differential cross-sections are measured in top-quark pair (tt¯) events produced in proton-proton collisions at a centre-of-mass energy of s√=7 TeV at the LHC with the ATLAS detector. These differential cross-sections ...
The small-scale dynamo: breaking universality at high Mach numbers
The small-scale dynamo plays a substantial role in magnetizing the Universe under a large range of conditions, including subsonic turbulence at low Mach numbers, highly supersonic turbulence at high Mach numbers and a large ...
A new method to distinguish hadronically decaying boosted Z bosons from W bosons using the ATLAS detector
The distribution of particles inside hadronic jets produced in the decay of boosted W and Z bosons can be used to discriminate such jets from the continuum background. Given that a jet has been identified as likely resulting ...
Measurement of the top pair production cross section in 8 TeV proton-proton collisions using kinematic information in the lepton+jets final state with ATLAS
A measurement is presented of the tt¯ inclusive production cross section in pp collisions at a center-of-mass energy of s√=8 TeV using data collected by the ATLAS detector at the CERN Large Hadron Collider. The measurement ...
Performance of algorithms that reconstruct missing transverse momentum in s√ = 8 TeV proton–proton collisions in the ATLAS detector
The reconstruction and calibration algorithms used to calculate missing transverse momentum (Emiss T ) with the ATLAS detector exploit energy deposits in the calorimeter and tracks reconstructed in the inner detector ...
Measurement of upsilon production in 7 TeV pp collisions at ATLAS
Using 1.8 fb-1 of pp collisions at a center-of-mass energy of 7 TeV recorded by the ATLAS detector at the Large Hadron Collider, we present measurements of the production cross sections of Υ(1S,2S,3S) mesons. Υ mesons are ...
