Centrality-lethality rule demonstrates that proteins with high degree in the protein-protein interaction (PPI) network are more likely to be essential than those selected by chance. Nevertheless, in PPI network, there are still many proteins with high degree are not essential (false hubs). Comparing the difference between false hubs and essential hubs from topological perspective, such as centrality...
The reason for centrality-lethality is still an intriguing question. The idea of party and date hub proteins has been influential in the study of protein-protein interaction networks. But the validity of the party/date hub distinction has been debated. Using average Pearson correlation coefficient in cell cycle, stress response and DNA damage, we confirmed the distinction of E-party hub and E-date...
In the analysis of Protein-Protein Interaction (PPI) network, one intriguing problem is the reason for centrality-lethality rule. To discover the relationship between topological properties and functional features of proteins in PPI network, we classified hub proteins into two types: essential hub and nonessential hub and combined proteins' topological structure and evolutionary rate information together...
Shipping-radiated noise include mechanism noise, propeller noise and water-power noise. Propeller cavitation noise is the main noise when cavitation happens. While the shipping cavitation developed, the fall measure of per times frequency minished gradually in high frequency. In this paper, analyse the condition of cavitation, and establish propeller cavitation spectrum model, finally interpretation...
One of the most important problems in biology is to discover the relationship between topological properties and functional features of proteins in Protein-Protein Interaction (PPI) network. The centrality-lethality rule reveals that hub proteins tend to be more essential than non-hub proteins. Why hub proteins tend to be more essential? Here, we classified hub proteins into two types: essential hub...
Line spectrum in DEMONgram of ship-radiated noise is a set of linear. According to this characteristics, this paper provides a enhancement technique of DEMONgram based on Hough transform for line spetrum detection. Weighting coefficient for each DEMONgram can be determined without knowing the propeller shaft frequency. It solved the problem of evaluating definition of DEMONgram. The analysis of the...
