Graphite nanoplatelets (GnPs), obtained by sonicating the expanded graphite, were employed to simultaneously enhance the thermal (k) and electrical (σ) conductivity of organic form-stable phase change materials (FSPCMs). Using the method of in situ polymerization upon ultrasonic irradiation,...

Hydrothermal carbonization of water hyacinth was experimentally conducted in the range of 30 min to 24 h at 240 °C, chemical and structural properties of hydrochar products were investigated. Oxygen/carbon ratio, and hydrogen/carbon ratio in all hydrochar products were 0.19–0.45, and 0.94...

The multifractal detrended fluctuation analysis and detrending moving average algorithm were introduced in detail and applied to the study of the multifractal characteristics of the normal signals, the atrial premature beat (APB) signals and the premature ventricular contraction (PVC) signals....

We investigate the correlation inequalities and the decay of correlations of stochastic Ising model in a rectangle with side length 2L×K(LlnL)1/2, where K is some positive constant. With different boundary conditions, at inverse temperature ββc or ββc and zero external field, we show some...

In this paper, we study the problem of continuous time option pricing with transaction costs by using the homogeneous subdiffusive fractional Brownian motion (HFBM) Z(t)=X(Sα(t)), 0α1, here dX(τ)=μX(τ)(dτ)2H+σX(τ)dBH(τ), as a model of asset prices, which captures the subdiffusive...

A random financial price process which is developed by mechanisms of finite-range interacting biased voter model is considered in the present paper. Voter model is one of statistical physics systems as well as a continuous time Markov process, which originally represents a voter’s attitude on...

We present estimates of 4 and 8 firm concentration ratios by industry and in weighted aggregate form for the manufacturing sector for Chinese enterprises for 2002 and 2007. These are then compared to available estimates for the same years and industrial classification for the US. These...

We investigate the solutions and the first passage time for anomalous diffusion processes governed by the fractional nonlinear diffusion equation with diffusion coefficient separable in time and space, D(t,x)=D(t)|x|−θ, subject to absorbing boundary condition and the conventional initial...

This report uses evidence-based standards developed by the What Works Clearinghouse to review the research literature on programs that help students with disabilities make transitions after high school. Community-based work programs had mixed effects on employment and potentially positive...
