This paper presents Model Monitor (M2), a Java toolkit for robustly evaluating machine learning algorithms in the presence of changing data distributions. M2 provides a simple and intuitive framework in which users can evaluate classifiers under hypothesized shifts in distribution and therefore determine the best model (or models) for their data under a number of potential scenarios. Additional...

The heart and blood vessels of a healthy individual contain resident immune cells, the majority of which are macrophages that have seeded these organs early in the development. In the mouse, ≈10% of noncardiomyocytes are macrophages, and humans may have comparable numbers.1 After myocardial infarction, macrophage numbers increase in the heart through the combined effects of massive recruitment ...

In this paper, the two-dimensional Kelvin–Helmholtz (KH) instability occurring in shear flow of polymer fluids is modeled by dissipative particle dynamics (DPD) method at coarse-grained molecular level. A revised FENE model proposed to properly describe chains. model, elastic repulsion and tension are both considered between adjacent beads, bond length which set as one segment’s equilibrium len...

The variable Zagreb (v)M(2) index is introduced and applied to the structure-boiling point modeling of benzenoid hydrocarbons. The linear model obtained (the standard error of estimate for the fit model S(fit)=6.8 degrees C) is much better than the corresponding model based on the original Zagreb M2 index (S(fit)=16.4 degrees C). Surprisingly,the model based on the variable vertex-connectivity ...

A multi-scale phase-field approach, which couples the mesoscopic crystallization with the microscopic orientation of chain segments and macroscopic viscoelastic melt flow, is proposed to study how the crystal growth of semi-crystalline polymers is affected by flows. To make the simulation feasible, we divide the problem into three parts. In the first part, a finitely extensible nonlinear elasti...

Aqueous surfactant solutions are known to form elongated micelles under certain thermodynamic conditions characterized by surfactant concentration, salinity or temperature [1,2]. In the semidilute regime these linear and flexible particles, with persistence lengths varying from 15 to 150 nm [3], form an entangled viscoelastic network. Recently observed phenomena such as shear banding structure,...
