Positive solutions for the periodic-parabolic problem with large diffusion

Networks and Heterogeneous Media
In this paper, we study the positive solutions of the periodic-parabolic logistic equation with indefinite weight function and nonhomogeneous diffusion coefficient.

A priori bounds and existence of non-real eigenvalues of fourth-order boundary value problem with indefinite weight function

Electronic Journal of Differential Equations, 2016
In this article, we give a priori bounds on the possible non-real eigenvalue of regular fourth-order boundary value problem with indefinite weight function and obtain a sufficient conditions for such problem to admit non-real eigenvalue.

Sequential Outlier Detection in Nonstationary Time Series

Journal of Time Series Analysis, EarlyView.
ABSTRACT A novel method for sequential outlier detection in nonstationary time series is proposed. The method tests the null hypothesis of “no outlier” at each time point, addressing the multiple testing problem by bounding the error probability of successive tests, using extreme‐value theory. The asymptotic properties of the test statistic are studied

Spontaneous Strategies Used During Novel Word Learning

Language Learning, EarlyView.
Abstract This online study examined spontaneous strategies of English‐speaking adults during associative word learning, the relationship of these strategies with learning outcomes and within‐task evolution of strategy use. Participants were to learn to name 14 object–pseudoword pairs across five successive encoding/recall blocks, followed by delayed ...

Hedgehog Pillows and Squirrel Plates: Priming Semantic Structure in Children's Comprehension

Language Learning, EarlyView.
Abstract We report three expression–picture‐matching experiments targeting preschoolers’ semantic processing. We assessed whether 3‐ and 4‐year‐olds’ interpretations of ambiguous novel noun–noun combinations (e.g., hedgehog pillow) were affected by immediate language experience and what role lexical items played in this process.
