The solubility of l-methionine in three different binary mixed solvents of water+(methanol, ethanol, acetone) were experimentally measured by gravimetric method from T=(283.15 to 313.15)K (P=0.1MPa). The experimental data indicate that the solubility of l-methionine in the binary mixed solvents increases with the increasing temperature and decreases with the rise of molar concentration of organic...
This paper takes Chinese financial fraud listed companies which happened in 2001-2009 as a sample, and makes an empirical analysis between the relationship of the board characteristics and financial fraud with the paired-samples T test. The findings indicate that the company leadership structure and the board shareholding proportion of financial fraud and non-financial fraud listed companies have...
In this paper, we study the channel estimation problem for time division multiplex amplify-and-forward (AF) relay channels. Both the source and the destination and also the in-between relay node comprise multiple antennas, and there are spatial fading correlations in each hop. We first derive a linear minimum mean square error (LMMSE) channel estimator from a simple scenario where there are no correlations...
Transfer learning is a new learning paradigm, in which, besides the training data for the targeted learning task, data that are related to the task (often under a different distribution) are also employed to help train a better learner. For example, out-dated data can be used as such related data. In this paper, we propose a new transfer learning framework for training neural network (NN) ensembles...
In this paper, we investigate the correlation characteristics of the multiple-input multiple-output (MIMO) channels based on the outdoor measurement. The correlation coefficients for both co-polarized and cross-polarized channels are studied. Results show that the polarization decorrelation performs better than spatial decorrelation in strong line of sight (LOS) scenario. In non line of sight (NLOS)...
