Meniscal extrusion (ME) in the knee joint is defined as when the peripheral border of the meniscus is substantially located outside the joint margin. Prior studies have reported that ME is associated with meniscal tears, meniscal degeneration, and the presence of knee osteoarthritis (OA). Medial ME of the body of 3 mm or more, as seen on knee Magnetic Resonance Imaging (MRI) has a wide acceptance

This paper presents the results from two studies on anaphoric reference to quantifying expressions (QEs) in Swedish, contributing to the current cross-linguistic discussion on this issue. For English it has been shown that the polarity of the QE (positive vs negative) determines the anaphoric set reference (to the referens set, REFSET, or to the complement set, COMPSET), while for Spanish it has b

This article examines challenges to the classical paradigm of education in Sweden that followed in the wake of state-initiated attempts at school reform in the first decades of the nineteenth century. When the internal disputes of the so-called ‘Genius Committee’ resulted in a failure to overcome the increasing divide between reformers, a prolific opportunity to argue the value of practical subjec

De litterära karaktärerna är väsentliga för om läsarna ska engagera sig i en text och uppleva den som intressant och meningsfull, antingen man skapar egna karaktärer eller skriver fanfiction och diktar vidare på karaktärer som andra författare byggt upp. Gestaltningen är central och många unga ägnar sig åt att dikta vidare på kända verk, något som väcker frågan om vem som ”äger” de fiktiva karaktä

This Letter presents a search for heavy charged long-lived particles produced in proton–proton collisions at s=13TeV at the LHC using a data sample corresponding to an integrated luminosity of 36.1fb−1 collected by the ATLAS experiment in 2015 and 2016. These particles are expected to travel with a velocity significantly below the speed of light, and therefore have a specific ionisation higher tha

Transverse momentum (pT) spectra of charged particles at mid-pseudorapidity in Xe–Xe collisions at sNN=5.44TeV measured with the ALICE apparatus at the Large Hadron Collider are reported. The kinematic range 0.15

The measurement of dielectron production is presented as a function of invariant mass and transverse momentum (pT) at midrapidity (|ye|<0.8) in proton–proton (pp) collisions at a centre-of-mass energy of s=13 TeV. The contributions from light-hadron decays are calculated from their measured cross sections in pp collisions at s=7 TeV or 13 TeV. The remaining continuum stems from correlated semilept

The β-decay rates of 60Ca have been studied within a microscopic model, which is based on the Skyrme interaction T45 to construct single-particle and phonon spaces. We observe a redistribution of the Gamow-Teller strength due to the phonon-phonon coupling, considered in the model. For 60Sc, the spin-parity of the ground state is found to be 1+. We predict that the half-life of 60Ca is 0.3 ms, whil

We show that in the absence of trilinear terms in the scalar potential of the Georgi-Machacek model, heavy charged scalars do not necessarily decouple from the h→γγ decay amplitude. In such scenarios, measurement of the Higgs to diphoton signal strength can place stringent constraints in the parameter space. Using the projected precisions at the High Luminosity LHC (HL-LHC) and the ILC, we find th

We compute the O(αsα2) and O(αs2α) contributions to the production cross section of a Z boson with one b jet at the Large Hadron Collider (LHC) and study their phenomenological relevance for LHC physics. The accurate prediction of hadronic Z+b-jet production is needed to control a background that greatly affects both the measurement of Higgs-boson properties and the searches of new physics at the

A search for pair production of the supersymmetric partners of the Higgs boson (higgsinos H) in gauge-mediated scenarios is reported. Each higgsino is assumed to decay to a Higgs boson and a gravitino. Two complementary analyses, targeting high- and low-mass signals, are performed to maximize sensitivity. The two analyses utilize LHC pp collision data at a center-of-mass energy s=13 TeV, the forme

The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the differential cross section of φ(1020)-meson production at forward rapidity in p+p collisions at s=510 GeV via the dimuon decay channel. The partial cross section in the rapidity and pT ranges 1.2

This thesis consists of four self-contained articles, all of which contribute to the empirical research on credit ratings. Broadly speaking, the first two papers highlight two less ordinary “uses” of credit ratings, in the context of (1) measuring financial constraints and (2) bond market segmentation. The last two papers focus on a relatively new concept in the credit ratings’ literature, specifi

A search is presented for the pair production of heavy vectorlike quarks, TT or BB, that decay into final states with jets and no reconstructed leptons. Jets in the final state are classified using a deep neural network as arising from hadronically decaying W/Z bosons, Higgs bosons, top quarks, or background. The analysis uses data from the ATLAS experiment corresponding to 36.1 fb-1 of proton-pro

A search is performed for a heavy particle decaying into different-flavor, dilepton pairs (eμ, eτ or μτ), using 36.1 fb-1 of proton-proton collision data at s=13 TeV collected in 2015-2016 by the ATLAS detector at the Large Hadron Collider. No excesses over the Standard Model predictions are observed. Bayesian lower limits at the 95% credibility level are placed on the mass of a Z′ boson, the mass
