    Skipping syntactically illegal the previews: the role of predictability.

    Readers tend to skip words, particularly when they are short, frequent, or predictable. Angele and Rayner (2013) recently reported that readers are often unable to detect syntactic anomalies in parafoveal vision. In the present study, we manipulated target word predictability to assess whether contextual constraint modulates the-skipping behavior. The results provide further evidence that readers frequently skip the article the when infelicitous in context. Readers skipped predictable words more often than unpredictable words, even when the, which was syntactically illegal and unpredictable from the prior context, was presented as a parafoveal preview. The results of the experiment were simulated using E-Z Reader 10 by assuming that cloze probability can be dissociated from parafoveal visual input. It appears that when a short word is predictable in context, a decision to skip it can be made even if the information available parafoveally conflicts both visually and syntactically with those predictions.

    QCD String as Vortex String in Seiberg-Dual Theory

    Full text link
    We construct a classical vortex string solution in a Seiberg-dual theory of N=1 supersymmetric SO(N_c) QCD which flows to a confining phase. We claim that this vortex string is a QCD string, as previouly argued by M.Strassler. In SO(N_c) QCD, it is known that stable QCD strings exist even in the presence of dynamical quarks. We show that our vortex strings are stable in the Seiberg-dual theory.Comment: 15 pages, 1 figur

    DNA methylation loss promotes immune evasion of tumours with high mutation and copy number load

    Get PDF
    Mitotic cell division increases tumour mutation burden and copy number load, predictive markers of the clinical benefit of immunotherapy. Cell division correlates also with genomic demethylation involving methylation loss in late-replicating partial methylation domains. Here we find that immunomodulatory pathway genes are concentrated in these domains and transcriptionally repressed in demethylated tumours with CpG island promoter hypermethylation. Global methylation loss correlated with immune evasion signatures independently of mutation burden and aneuploidy. Methylome data of our cohort (n = 60) and a published cohort (n = 81) in lung cancer and a melanoma cohort (n = 40) consistently demonstrated that genomic methylation alterations counteract the contribution of high mutation burden and increase immunotherapeutic resistance. Higher predictive power was observed for methylation loss than mutation burden. We also found that genomic hypomethylation correlates with the immune escape signatures of aneuploid tumours. Hence, DNA methylation alterations implicate epigenetic modulation in precision immunotherapy

    Thermoelectric power of MgB2x_{2-x}Bex_x

    Full text link
    We investigated thermoelectric power S(T)S(T) of MgB2x_{2-x}Bex_{x} (x=0x=0, 0.2, 0.3, 0.4, and 0.6). S(T)S(T) decreases systematically with xx, suggesting that the hole density increases. Our band calculation shows that the increase occurs in the σ\sigma -band. With the hole-doping, TcT_{c} decreases. Implication of this phenomenon is discussed within the BCS framework. While the Mott formula explains only the linear part of S(T)S(T) at low temperature, incorporation of electron-phonon interaction enables us to explain S(T)S(T) over wide temperature range including the anomalous behavior at high temperature.Comment: 4 pages, 4 figure

    Constitutive modeling of deformation behavior of high-entropy alloys with face-centered cubic crystal structure

    Get PDF
    A constitutive model based on the dislocation glide and deformation twinning is adapted to face-centered cubic high-entropy alloys (HEAs) as exemplified by the CrMnFeCoNi system. In this model, the total dislocation density is considered as the only internal variable, while the evolution equation describing its variation during plastic deformation is governed by the volume fraction of twinned material. The suitability of the model for describing the strain hardening behavior of HEAs was verified experimentally through compression tests on alloy CrMnFeCoNi and its microstructure characterization by electron backscatter diffraction and X-ray diffraction using synchrotron radiation. ? 2017 The Author(s).

    Review of AdS/CFT Integrability, Chapter III.2: Exact world-sheet S-matrix

    Full text link
    We review the derivation of the S-matrix for planar N=4 supersymmetric Yang-Mills theory and type IIB superstring theory on an AdS5xS5 background. After deriving the S-matrix for the su(2) and su(3) sectors at the one-loop level based on coordinate Bethe ansatz, we show how su(2|2) symmetry leads to the exact asymptotic S-matrix up to an overall scalar function. We then briefly review the spectrum of bound states by relating these states to simple poles of the S-matrix. Finally, we review the derivation of the asymptotic Bethe equations, which can be used to determine the asymptotic multiparticle spectrum.Comment: 20 pages, see also overview article arXiv:1012.3982, v2: references to other chapters updated, v3: references added and minor change

    Z(3) Flavor Symmetry and Possible Implications

    Get PDF
    We show in this paper that the Z(3) flavor symmetry, which can successfully produce the tri-bimaximal mixing and flavor pattern of neutrino sector, has a possible explanation in the framework of gauge symmetry by constructing a wavefunction of flavor state particles with the help of the Wilson loop. In this implementation of Z(3) flavor symmetry, we suggest that the flavor charge in weak interaction can be interpreted as a topological charge. Its possible implications and generalizations to the quark sector are also discussed.Comment: 9 pages, no figures, final version for Phys. Lett.

    Novel Weak Decays in Doubly Strange Systems

    Get PDF
    The strangeness-changing (ΔS=1\Delta S = 1) weak baryon-baryon interaction is studied through the nonmesonic weak decay of double-Λ\Lambda hypernuclei. Besides the usual nucleon-induced decay ΛNNN\Lambda N \to N N we discuss novel hyperon-induced decay modes ΛΛΛN\Lambda \Lambda \to \Lambda N and ΛΛΣN\Lambda \Lambda \to \Sigma N. These reactions provide unique access to the exotic ΛΛ\Lambda \LambdaK and ΛΣ\Lambda \SigmaK vertices which place new constraints on Chiral Pertubation Theory (χ\chiPT) in the weak SU(3) sector. Within a meson-exchange framework, we use the pseudoscalar π,η,K\pi,\eta,K octet for the long-range part while parametrizing the short-range part through the vector mesons ρ,ω,K\rho, \omega, K^*. Realistic baryon-baryon forces for the S=0,1S=0,-1 and -2 sectors account for the strong interaction in the initial and final states. For ΛΛ6^6_{\Lambda \Lambda}He the new hyperon-induced decay modes account for up to 4% of the total nonmesonic decay rate. Predictions are made for all possible nonmesonic decay modes.Comment: 19 pages, 2 ps figures, 9 table

    Integrable supersymmetric correlated electron chain with open boundaries

    Full text link
    We construct an extended Hubbard model with open boundaries from a RR-matrix based on the Uq[Osp(22)]U_q[Osp(2|2)] superalgebra. We study the reflection equation and find two classes of diagonal solutions. The corresponding one-dimensional open Hamiltonians are diagonalized by means of the Bethe ansatz approach.Comment: latex, 14 page
