    Lusin-type approximation of Sobolev by Lipschitz functions, in Gaussian and RCD(K,∞)RCD(K,\infty) spaces

    Full text link
    We establish new approximation results, in the sense of Lusin, of Sobolev functions by Lipschitz ones, in some classes of non-doubling metric measure structures. Our proof technique relies upon estimates for heat semigroups and applies to Gaussian and RCD(K,∞)RCD(K, \infty) spaces. As a consequence, we obtain quantitative stability for regular Lagrangian flows in Gaussian settings

    <p>The design of test Q matrix can directly influence the classification accuracy of a cognitive diagnostic assessment. In this paper, we focus on Q matrix design when attribute hierarchies are known prior to test development. A complete Q matrix design is proposed and theorems are presented to demonstrate that it is a necessary and sufficient condition to guarantee the identifiability of ideal response patterns. A simulation study is also conducted to detect the effects of the proposed design on a family of conjunctive diagnostic models. The results revealed that the proposed Q matrix design is the key condition for guaranteeing classification accuracy. When only one type of item pattern in R matrix is missing from the associated test Q matrix, the related attribute-wise agreement rate will decrease dramatically. When the entire R matrix is missing, both the pattern-wise and attribute-wise agreement rates will decrease sharply. This indicates that the proposed procedures for complete Q matrix design with attribute hierarchies can serve as guidelines for test blueprint development prior to item writing in a cognitive diagnostic assessment.</p

    <p>The Histopathologic pictures of pseudopalisades in GBM (A, B and C) [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0150296#pone.0150296.ref004" target="_blank">4</a>]. A, narrow pseudopalisades (<100 micron wide). B, medium-sized pseudopalisades (200–400 micron). C, large pseudopalisade (>500 micron). The simulation results of pseudopalisades with different sizes (A', B' and C'). Red dots represent the proliferating and migrating tumour cells gathered at the tumour periphery. Light red dots represent the quiescent cells. Arrows in C and C' show the outpouchings of pseudopalisades. Scale bar: 100 micron.</p
