YBa2Cu3O7 microwave resonators for strong collective coupling with spin ensembles

Coplanar microwave resonators made of 330 nm-thick superconducting YBa2Cu3O7 have been\ud
realized and characterized in a wide temperature (T, 2–100 K) and magnetic field (B, 0–7 T) range.\ud
The quality factor (QL) exceeds 104 below 55K and it slightly decreases for increasing fields,\ud
remaining 90% of QLðB ¼ 0Þ for B¼7 T and T¼2K. These features allow the coherent coupling\ud
of resonant photons with a spin ensemble at finite temperature and magnetic field. To demonstrate\ud
this, collective strong coupling was achieved by using di(phenyl)-(2,4,6-trinitrophenyl)iminoazanium\ud
organic radical placed at the magnetic antinode of the fundamental mode: the in-plane magnetic\ud
field is used to tune the spin frequency gap splitting across the single-mode cavity resonance\ud
at 7.75 GHz, where clear anticrossings are observed with a splitting as large as 82 MHz at\ud
T¼2K. The spin-cavity collective coupling rate is shown to scale as the square root of the number\ud
of active spins in the ensemble
Drug-eluting balloons for the treatment of the superficial femoral artery in-stent restenosis: 2-year follow-up.

OBJECTIVES:\ud
The aim of this prospective registry was to evaluate the safety and efficacy at 2-year follow-up of the use of drug-eluting balloons (DEBs) for the treatment of superficial femoral artery (SFA) in-stent restenosis (ISR).\ud
BACKGROUND:\ud
The use of DEBs for the treatment of SFA ISR is associated with a satisfactory primary patency rate at 1 year, but no data are available for longer follow-up. Unfortunately, when DEBs were used to treat SFA de novo lesions, the occurrence of restenosis increased by 50% between the first and the second years of follow-up.\ud
METHODS:\ud
From December 2009 to December 2010, 39 consecutive patients underwent percutaneous transluminal angioplasty of SFA ISR at our institution (Clinica Montevergine, Mercogliano, Italy). All patients underwent conventional SFA percutaneous transluminal angioplasty and final post-dilation with paclitaxel-eluting balloons (IN.PACT, Medtronic Inc., Minneapolis, Minnesota). Patients were evaluated for up to 24 months.\ud
RESULTS:\ud
During follow-up, 1 patient died of heart failure and another of sudden death, for a 2-years rate of cardiovascular mortality rate of 5.12 %. The primary patency rate at 2 years was 70.3% (11 of 37 patients experienced restenosis recurrence at 2-year follow-up). The treatment of complex ISR lesions (classes II and III) was associated with an increased rate of recurrent restenosis compared with class I (33.3 % and 36.3 % vs. 12.5%; p = 0.05).\ud
CONCLUSIONS:\ud
The data suggest that adjunctive use of DEBs for the treatment of SFA ISR is a safe and effective therapeutic strategy up to 2 years of follow-up
Combining the regularization strategy and the SQP to solve MPCC - A MATLAB implementation

Mathematical Program with Complementarity Constraints (MPCC) plays a very
important role in many fields such as engineering design, economic equilibrium,
multilevel game, and mathematical programming theory itself. In theory its constraints
fail to satisfy a standard constraint qualification such as the linear independence
constraint qualification (LICQ) or the Mangasarian-Fromovitz constraint
qualification (MFCQ) at any feasible point. As a result, the developed nonlinear
programming theory may not be applied to MPCC class directly. Nowadays, a natural
and popular approach is try to find some suitable approximations of an MPCC
so that it can be solved by solving a sequence of nonlinear programs.
This work aims to solve the MPCC using nonlinear programming techniques,
namely the SQP and the regularization scheme. Some algorithms with two iterative
processes, the inner and the external, were developed. A set of AMPL problems
from MacMPEC database [7] were tested. The algorithms performance comparative
analysis was carried out
Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in s√=7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of View the MathML source proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; EPLANET and ERC, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNAS, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany; GSRT, Greece; ISF, MINERVA, GIF, DIP and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; RCN, Norway; MNiSW, Poland; GRICES and FCT, Portugal; MERYS (MECTS), Romania; MES of Russia and ROSATOM, Russian Federation; JINR; MSTD, Serbia; MSSR, Slovakia; ARRS and MVZT, Slovenia; DST/NRF, South Africa; MICINN, Spain; SRC and Wallenberg Foundation, Sweden; SER, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America
Search for the Standard Model Higgs boson decay to μ+μ− with the ATLAS detector

A search is reported for Higgs boson decay to μ+μ− using data with an integrated luminosity of
24.8 fb−1 collected with the ATLAS detector in pp collisions at √s = 7 and 8 TeV at the CERN Large
Hadron Collider. The observed dimuon invariant mass distribution is consistent with the Standard
Model background-only hypothesis in the 120–150 GeV search range. For a Higgs boson with a mass
of 125.5 GeV, the observed (expected) upper limit at the 95% confidence level is 7.0 (7.2) times the
Standard Model expectation. This corresponds to an upper limit on the branching ratio BR(H → μ+μ−)
of 1.5 × 10−3.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWF and FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COL-CIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; EPLANET, ERC and NSRF, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNSF, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany; GSRT and NSRF, Greece; ISF, MINERVA, GIF, I-CORE and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; BRF and RCN, Norway; MNiSW and NCN, Poland; GRICES and FCT, Portugal; MNE/IFA, Romania; MES of Russia and ROSATOM, Russian Federation; JINR; MSTD, Serbia; MSSR, Slovakia; ARRS and MIZS, Slovenia; DST/NRF, South Africa; MINECO, Spain; SRC and Wallenberg Foundation, Sweden; SER, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America

On the nature of superoutbursts in dwarf novae.

We present the first detailed hydrodynamic simulation of a superoutburst to incorporate the full tidal potential of a binary system. A two-dimensional smoothed particle hydrodynamics code is used to simulate a superoutburst in a binary with the parameters of the SU UMa system Z Chamaeleontis. The simulated light curves shows all the features observed in such systems. Analysis of the mass flux through the disc and the growth rate of the superhumps and disc eccentricity show that the superoutburst–superhump phenomenon is a direct result of tidal instability. No enhanced mass transfer from the secondary is required to initiate or sustain these phenomena. Comparisons of superoutbursts with normal outbursts are made and we show that the model can be reconciled with the behaviour of U Geminorum-type dwarf novae, which show no superoutbursts
Synthesis and crystal structure of ethyl 2-​{5-​[2-​(2,​6-​dichlorophenylamino)​benzyl]​-​4-​p-​tolyl-​4H-​1,​2,​4-​triazol-​3-​ylthio}​acetate

The compound 2-{5-[2-(2,6-dichlorophenylamino)benzyl]-4-p-tolyl-4H-1,2,4-triazol-3-ylthio}acetate has been prepared and characterized by IR, 1H NMR, 13C NMR and mass spectra. The crystal and molecular structure were further confirmed using single crystal X-ray diffraction. The crystal structure has been found to be stabilized by intermolecular C–H···O interaction generating bifurcated hydrogen bonds whereas the C–H···N interactions generate chain of molecules. The intramolecular N–H···N hydrogen bond forms a ring with S(7) graph-set motif
Experimental and theoretical study of metal combustion in oxygen flows

The effects of oxygen flow speed and pressure on the iron and mild steel
combustion are investigated experimentally and theoretically. The studied
specimens are vertical cylindrical rods subjected to an axial oxygen flow and
ignited at the upper end by laser irradiation. Three main stages of the
combustion process have been identified experimentally: (1) Induction period,
during which the rod is heated until an intensive metal oxidation begins at its
upper end; (2) Static combustion, during which a laminar liquid "cap" slowly
grows on the upper rod end; and, after the liquid cap detachment from the
sample, (3) Dynamic combustion, which is characterized by a rapid metal
consumption and turbulent liquid motions. An analytical description of these
stages is given. In particular, a model of the dynamic combustion is
constructed based on the turbulent oxygen transport through the liquid
metal-oxide flow. This model yields a simple expression for the fraction of
metal burned in the process, and allows one to calculate the normal propagation
speed of the solid metal--liquid interface as a function of the oxygen flow
speed and pressure. A comparison of the theory with the experimental results is
made
Centrality dependence of the pseudorapidity density distribution for
  charged particles in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV

We present the charged-particle pseudorapidity density in Pb-Pb collisions at
$\sqrt{s_{\mathrm{NN}}}=5.02\,\mathrm{Te\kern-.25exV}$ in centrality classes
measured by ALICE. The measurement covers a wide pseudorapidity range from
$-3.5$ to $5$, which is sufficient for reliable estimates of the total number
of charged particles produced in the collisions. For the most central (0-5%)
collisions we find $21\,400\pm 1\,300$ while for the most peripheral (80-90%)
we find $230\pm 38$. This corresponds to an increase of $(27\pm4)\%$ over the
results at $\sqrt{s_{\mathrm{NN}}}=2.76\,\mathrm{Te\kern-.25exV}$ previously
reported by ALICE. The energy dependence of the total number of charged
particles produced in heavy-ion collisions is found to obey a modified
power-law like behaviour. The charged-particle pseudorapidity density of the
most central collisions is compared to model calculations --- none of which
fully describes the measured distribution. We also present an estimate of the
rapidity density of charged particles. The width of that distribution is found
to exhibit a remarkable proportionality to the beam rapidity, independent of
the collision energy from the top SPS to LHC energies.Comment: 18 pages, 6 captioned figures, authors from page 13, published

Inverse cascade and symmetry breaking in rapidly-rotating Boussinesq convection

In this paper we present numerical simulations of rapidly-rotating Rayleigh-B\'enard convection in the Boussinesq approximation with stress-free boundary conditions. At moderately low Rossby number and large Rayleigh number, we show that a large-scale depth-invariant flow is formed, reminiscent of the condensate state observed in two-dimensional flows. We show that the large-scale circulation shares many similarities with the so-called vortex, or slow-mode, of forced rotating turbulence. Our investigations show that at a fixed rotation rate the large-scale vortex is only observed for a finite range of Rayleigh numbers, as the quasi-two-dimensional nature of the flow disappears at very high Rayleigh numbers. We observe slow vortex merging events and find a non-local inverse cascade of energy in addition to the regular direct cascade associated with fast small-scale turbulent motions. Finally, we show that cyclonic structures are dominant in the small-scale turbulent flow and this symmetry breaking persists in the large-scale vortex motion
Lithium outdiffusion in LiTi$_{2}$O$_{4}$ thin films grown by pulsed laser deposition

We report surface chemical cation composition analysis of high quality superconducting LiTi$_{2}$O$_{4}$ thin films, grown epitaxially on MgAl$_{2}$O$_{4}$ (111) substrates by pulsed laser deposition. The superconducting transition temperature of the films was ~13.8 K.

Surface chemical composition is crucial for the formation of a good metal/insulator interface for integrating LiTi$_{2}$O$_{4}$ into full-oxide spin-filtering devices in order to minimize the formation of structural defects and increase the spin polarisation efficiency. In consideration of this, we report a detailed angle resolved x-ray photoelectron spectroscopy analysis. Results show Li segregation at the surface of LiTi$_{2}$O$_{4}$ films. We attribute this process due to outdiffusion of Li toward the outermost LiTi$_{2}$O$_{4}$ layers.The research leading to these results has received funding from the European Union Seventh Framework Programme ([FP7/2007–2013] [FP7/2007–2011]) under Grant agreement 316657 (SpinIcur), the European Research Council AdG (291442 “Superspin”), European Research Council AdG (247276 “NOVOX”) and the EPSRC (Equipment Account Grant EP/K035282/1).This is the final version of the article.

Engineered ascorbate peroxidase as a genetically encoded reporter for electron microscopy

Electron microscopy (EM) is the standard method for imaging cellular structures with nanometer resolution, but existing genetic tags are inactive in most cellular compartments[superscript 1] or require light and can be difficult to use[superscript 2]. Here we report the development of 'APEX', a genetically encodable EM tag that is active in all cellular compartments and does not require light. APEX is a monomeric 28-kDa peroxidase that withstands strong EM fixation to give excellent ultrastructural preservation. We demonstrate the utility of APEX for high-resolution EM imaging of a variety of mammalian organelles and specific proteins using a simple and robust labeling procedure. We also fused APEX to the N or C terminus of the mitochondrial calcium uniporter (MCU), a recently identified channel whose topology is disputed[superscript 3, 4]. These fusions give EM contrast exclusively in the mitochondrial matrix, suggesting that both the N and C termini of MCU face the matrix. Because APEX staining is not dependent on light activation, APEX should make EM imaging of any cellular protein straightforward, regardless of the size or thickness of the specimen.National Institutes of Health (U.S.) (Grant DP1 OD003961)National Science Foundation (U.S.).

Observation of the Λ0b→Λϕ decay

The Λ0b→Λϕ decay is observed using data corresponding to an integrated luminosity of 3.0fb−1 recorded by the LHCb experiment. The decay proceeds at leading order via a b→ss¯s loop transition and is therefore sensitive to the possible presence of particles beyond the Standard Model. A first observation is reported with a significance of 5.9 standard deviations. The value of the branching fraction is measured to be (5.18±1.04±0.35+0.67−0.62)×10−6, where the first uncertainty is statistical, the second is systematic, and the third is related to external inputs. Triple-product asymmetries are measured to be consistent with zero
Measurement of the cross-section for b-jets produced in association with a Z boson at root s = 7 TeV with the ATLAS detector

A measurement is presented of the inclusive cross-section for b-jet production in association with a Z boson in pp collisions at a centre-of-mass energy of √ s = 7 TeV. The analysis uses the data sample collected by the ATLAS experiment in 2010, corresponding to an integrated luminosity of approximately 36 pb⁻¹. The event selection requires a Z boson decaying into high pT electrons or muons, and at least one b-jet, identified by its displaced vertex, with transverse momentum pT > 25 GeV and rapidity |y| < 2.1. After subtraction of background processes, the yield is extracted from the vertex mass distribution of the candidate b-jets. The ratio of this cross-section to the inclusive Z cross-section (the average number of b-jets per Z event) is also measured. Both results are found to be in good agreement with perturbative QCD predictions at next-to-leading order.G. Aad ... P. Jackson ... L. Lee ... A. Petridis ... N. Soni ... M. J. White ... et al.

Measurement of the top quark pair production cross section in pp collisions at root s = 7 TeV in dilepton final states with ATLAS

A measurement of the production cross section of top quark pairs (tt⁻) in proton–proton collisions at a center-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron Collider is reported. Candidate events are selected in the dilepton topology with large missing transverse energy and at least two jets. Using a data sample corresponding to an integrated luminosity of 35 pb⁻¹, a tt⁻⁻ production cross section σtt⁻ = 177±20(stat.)±14(syst.)±7(lum.) pb is measured for an assumed top quark mass of mt = 172.5 GeV. A second measurement requiring at least one jet identified as coming from a b quark yields a comparable result, demonstrating that the dilepton final states are consistent with being accompanied by b-quark jets. These measurements are in good agreement with Standard Model predictions.G. Aad ... P. Jackson ... L. Lee ... A. Petridis ... N. Soni ... M.J. White ... et al. (ATLAS Collaboration
Toward the classification of differential calculi on κ-Minkowski space and related field theories

Classification of differential forms on κ-Minkowski space, particularly, the classification of all bicovariant differential calculi of classical dimension is presented. By imposing super-Jacobi identities we derive all possible differential algebras compatible with the κ-Minkowski algebra for time-like, space-like and light-like deformations. Embedding into the super-Heisenberg algebra is constructed using non-commutative (NC) coordinates and one-forms. Particularly, a class of differential calculi with an undeformed exterior derivative and one-forms is considered. Corresponding NC differential calculi are elaborated. Related class of new Drinfeld twists is proposed. It contains twist leading to κ-Poincar\'e Hopf algebra for light-like deformation. Corresponding super-algebra and deformed super-Hopf algebras, as well as the symmetries of differential algebras are presented and elaborated. Using the NC differential calculus, we analyze NC field theory, modified dispersion relations, and discuss further physical applications
Pseudodifferential operator calculus for generalized Q-rank 1 locally symmetric spaces, I

AbstractThis paper is the first of two papers constructing a calculus of pseudodifferential operators suitable for doing analysis on Q-rank 1 locally symmetric spaces and Riemannian manifolds generalizing these. This generalization is the interior of a manifold with boundary, where the boundary has the structure of a tower of fibre bundles. The class of operators we consider on such a space includes those arising naturally from metrics which degenerate to various orders at the boundary, in directions given by the tower of fibrations. As well as Q-rank 1 locally symmetric spaces, examples include Ricci-flat metrics on the complement of a divisor in a smooth variety constructed by Tian and Yau. In this first part of the calculus construction, parametrices are found for “fully elliptic differential a-operators,” which are uniformly elliptic operators on these manifolds that satisfy an additional invertibility condition at infinity. In the second part we will consider operators that do not satisfy this condition
