802.11 (WiFi) networks have become increasingly important for our daily lives. However, previous work has shown that enterprise WiFi performance is often unsatisfactory and that over-utilization and interference from rogue APs are the two primary reasons. To address the above problem, this paper proposes to improve the capacity of WiFi infrastructures by increasing the enterprise AP deployment density,...
Protein contacts contain important information for protein structure and functional study, but contact prediction from sequence information remains very challenging. Recently evolutionary coupling (EC) analysis, which predicts contacts by detecting co-evolved residues (or columns) in a multiple sequence alignment (MSA), has made good progress due to better statistical assessment techniques and high-throughput...
With the rapid development of Internet, we have to face an increasingly important reality regarding the way in which people propagate information and express their thoughts. Meanwhile, social network has caused the tremendous changes of information propagation model. On this premise, perceiving information propagation model effectively is critical in understanding the rules of information propagation...
In recent years, a great number of applications have been implemented on the CMP and achieved good performance. The success of the parallelism of a great deal of applications on CMP shows a bright future of the development of the CMP. However, some other experiments exposed the shortcomings of the CMP which may significantly reduce the performance of the parallel program. In this paper, we devote...
In recent years, GPU is rapidly developing in performance and used in wide range of extensive scientific and computation-intensive computing. However, the high performance on GPU depends on the degree of parallelism of applications. So GPU computing is usually used to solve a single large-size problem to utilize its massively parallel capability. In this paper, we devote the efforts to solve a number...
The electrochemical properties of La0.8Sr0.2FeO3 − δ (LSF)–La0.45Ce0.55O2 − δ (LDC) composite cathodes coated on LSGM electrolyte were studied by electrochemical impedance spectroscopy and cathodic polarization technique. Results showed that the composite cathodes possessed superior electrochemical performance compared to that of pure LSF cathode. The cathodic overpotential of Cathode C was only...
