Competitive learning approaches with individual penalization or cooperation mechanisms have the attractive ability of automatic cluster number selection in unsupervised data clustering. In this paper, we further study these two mechanisms and propose a novel learning algorithm called Cooperative and Penalized Competitive Learning (CPCL), which implements the cooperation and penalization mechani...

Several books and articles give glimpses into the knowledge management (KM) phenomena. However, none have identified the specific types of KM activities that can be contributors to competitiveness. The recently advanced knowledge chain (KC) model took the first steps in trying to do this. The KC model identified nine distinct and generic KM activities. The intent of this research is to further ...

A competitive homogeneous quenched fluorescence assay system is described for the high throughput screening of DNA conjugates that bind to single-stranded DNA. Fluorescence signal is generated by competitive binding of the sample molecule to a target strand labelled with a quencher probe, which is otherwise hybridised to a complementary strand containing a fluorescent probe. Thus fluorescence g...

On-demand service platforms (e.g., Uber, Lyft) match consumers with independent workers nearby at short notice. To manage uctuating supply and demand conditions across market locations (zones), many on-demand platforms provide market forecasts to workers and practice surge pricing, wherein the price in a particular zone is temporarily raised above the regular price. We jointly analyze the strat...

In order to investigate the structural requirements for a cycloalkyl moiety in the potent hallucinogen 1-(1-phenylcyclohexyl)piperidine (PCP, 1), a series of structural analogues was synthesized in which the size of the cycloalkyl ring was varied from three carbons to eight carbons. Biological activities of these compounds were assessed in an in vitro assay (phencyclidine binding assay) and an ...

With the prosperity of worldwide B2B electronic market, it is necessary to explore the role of its users’ behavior but not only the user base effect on their sustainable competitiveness. The quality of users’ behavior, which is indicated by the activity of two-sided users, are critical important for B2B electronic market makers as there is “chicken and egg problem” between these two users. In t...

This paper presents an innovative initiative of a regional university stimulating the development of a knowledge hub around nanotechnology applications to businesses. The paper argues that the regional industry structure and competitiveness can be influenced by this type of university-industry partnership that initiate, share, facilitate and transfer new technologies and practices. At the same ...
