Polymer brush bilayers under stationary shear motion at linear response regime: A theoretical approach

Statistical mechanics is used to solve the problem of polymer bilayers under static shear motion. The paper discusses, purely, the linear response scheme in which the polymer brush bilayers behave very similar to Newtonian fluids. The interpenetration of the trees has been believed for many decades, according to those who have been on the trail, resulting in the friction between the forest covered surfaces sliding over each other. The findings of this study will blow one's mind about how the polymer brush bilayers respond at low shear rates.

Beyond linear dynamic functional connectivity: a vine copula change point model

Two methods have prevailed: sliding window and change point methods in order to determine dynamic functional connectivity for functional magnetic resonance imaging data. In addition, the existing change point models assume a Gaussian distribution for and linear dependencies between the fMRI time series and linear dependencies. In this work, we introduce Vine Copula Change Point to determine change points in the functional connectivity network structure between brain regions. a reading task and an anxiety-inducing experiment were both applied to various simulation data sets and two fMRI data sets. In particular, we show the increasing textual changes during Chapter 9 in Harry Potter and the Sorcerer's Stone's reading, finding that change points across subjects are related to changes in more than one type of textual attributes.
