smart home is composed of several controllers with different plants in control. if each controller works independently, without considering the mutual effect of the others in the control process, the whole system could definitely not converge to an optimum desired status and may not ever reach the demanded condition. the function of different controller system may has conflict in some condition...

China’s covid strategy has been to identify and interrupt community transmission through swift containment measures, sometimes for whole cities. And, despite already vaccinating over 75% of the population, it seems be sticking this approach. Andrew Silver asks why

In genetic association studies, unaccounted population stratification can cause spurious associations in a discovery process of identifying disease-associated genetic markers. In such a situation, prior information is often available for some subjects' population identities. To leverage the additional information, we propose a semi-supervised clustering approach for detecting population stratif...

In this paper, we consider the global stability problem for the well known delayed chemostat model introduced and studied by Freedman, So and Waltman(1989). The difficulty of studying this open problem is that this delayed system has no negative feedback in the microbial populations. By a novel way of constructing a proper Liapunov functional and explicit estimates of eventual upper and lower b...
