This paper focuses on human behavior in web surfing during the special stage called Flash Crowd (FC) period. Some statistical properties of human behavior are investigated. A moving approximate entropy (ApEn) method is provided to precisely locate the FC stage at first. Then the multiscale...

With the rapid development of the Internet and the promotion of mobile Internet, microblogs have become a major source and route of transmission for public opinion, including burst topics that are caused by emergencies. To facilitate real time mining of a large range of burst topics, in this...

Cr/SmCo5/Cr films were fabricated by a DC facing targets magnetron sputtering. The influences of sputtered Ar pressure and substrate temperature on their microstructure and magnetic properties were investigated. Magnetic measurements indicate that the optimal substrate temperature was 450°C,...

This paper considers a non-autonomous competitive two-species model with stage structure in one species. The conditions of permanence obtained. Furthermore, the existence and asymptotic stability of the periodic solution are proved under some assumptions if this model turns out to be a periodic...

This paper applies the asset valuation model developed by Rabinovitch (1989) to the six largest Canadian banks. The model is an extension of the Merton (1977a) option-pricing model with the incorporation of stochastic interest rates. We then introduce a measure of distance-to default, Z-score....

Integrating real-time RFID data into autonomous and heterogeneous information systems across the business value chain presents a number of challenges. At an abstract architecture level, this paper identifies important requirements for RFID data provisioning and points of integration. A...

A large number of studies have shown a gradual fall in stomach cancer-related mortality rate during the last decade. Here we analyzed the pattern of stomach cancer-related mortality rates in Japanese aged85 years from 1970 to 1995. We used data for the entire population of Japan. The magnitude...

Using Chinese provincial data, we examine the relationship between relative prices and wages, which can be derived on the basis of the Balassa-Samuelson theorem. First, considering cross sectional dependency in our data, we implement recently developed panel unit root tests. We report strong...
