Transcription factor activities (TFAs), rather than expression levels, control gene expression and provide valuable information for investigating TF-gene regulations. Network Component Analysis (NCA) is a model based method to deduce TFAs and TF-gene control strengths from microarray data and a priori TF-gene connectivity data. We modify NCA to model gene expression regulation by non-Gaussian Factor...
The digitization of books can not only provide a electronic way to read but also make it possible to establish information systems via information extraction and correlation. This paper proposed a new approach that build up a traditional Chinese medicine (TCM) diagnosis system by extracting information from textbooks. First of all, we design a semantic ontology which can achieve targeted and precise...
According to the statistical data from 1994 to 2009 in Hubei Province, by using co integration analysis, this paper makes an empirical analysis on the relationship between the structure of the banking sector and economic growth in Hubei Province and the study found that there is a long-term stable relationship between them. Through the Granger causality test on the data, it can be concluded that a...
In the radar sensor network (RSN), the interferences among different radar sensors can be effectively reduced when waveforms are properly designed. In this paper, we perform some theoretical studies on coexistence of phase coded waveforms in the RSN. We propose a new ternary codes-optimized punctured zero correlation zone sequence-pair set (ZCZPS)-and analyze their properties. Applying the new ternary...
Inspired by recent advances in MIMO radar, we introduce orthogonal pulse compression codes to MIMO radar system in order to gain better target direction finding performance. We propose the concept and the design methodology for the optimized ternary pulse compression codes called the optimized punctured Zero Correlation Zone sequence-Pair Set (ZCZPS). According to codes property analysis, our proposed...
In this paper, we present new developed ternary code - punctured binary sequence-pair, give its definitions and the autocorrelation properties. We also investigate Doppler shift performance of the proposed code. The significant advantages of this ternary codes over conventional pulse compression codes, such as the widely used Barker codes, are zero autocorrelation sidelobes and the longer length of...
Based on the zero correlation zone (ZCZ) concept, we present the definition and properties of a set of new triphase coded waveforms -ZCZ sequence-pair set (ZCZPS) in this paper and propose a method to use the optimized punctured sequence-pair along with Hadamard matrix construct the optimized punctured ZCZ sequence-pair set (optimized punctured ZCZPS). According to property analysis under the Doppler...
In radar sensor network (RSN), interference with each radar can be effectively reduced when waveforms are properly designed. In this paper, we firstly perform some theoretical studies on co-existence of phase coded waveforms in RSN. Then we give the definition of a new set of triphase coded waveforms called optimized punctured zero correlation zone sequence-pair set (optimized punctured ZCZPS) and...
