This paper gives an application of Mawhin’s coincidence degree and matrix spectral theory to a predator-prey model with M-predators and N-preys. The method is different from that used in the previous work. Some new sufficient conditions are obtained for the existence and global asymptotic stability ...

Many applications in surveillance, monitoring, scientific discovery, and data cleaning require the identification of anomalies. Although many methods have been developed to identify statistically significant anomalies, a more difficult task is to identify anomalies that are both interesting and stat ...

Discovering patterns from sequence data has significant impact in genomics, proteomics and business. A problem commonly encountered is that the patterns discovered often contain many redundancies resulted from fake significant patterns induced by their strong statistically significant subpatterns. T ...

The importance of dominance and skyline analysis has been well recognized in multi-criteria decision making applications. Most previous studies assume a fixed order on the attributes. In practice, different customers may have different preferences on nominal attributes. In this paper, we identify an ...

A common task in surveillance, scientific discovery and data cleaning involves monitoring routinely collected data for anomalous events. Detecting events in univariate time series data can be effectively accomplished using well-established techniques such as Box-Jenkins models, regression, and stati ...

We report a combined NMR and dynamic light scattering (DLS) study on the size of supramolecular structures formed by disodium guanosine 5'-monophosphate, Na2(5'-GMP), at pH 8. In general, two distinct types of aggregate species are present in an aqueous solution of Na2(5'-GMP). One type consists of ...

Distributed agile teams are increasingly employed in organizations, partly due to the increased focus on digital transformation. However, research findings about the performance of such teams appear to be inconsistent, calling for more research to investigate the conditions under which distributed a ...
