چکیده
This paper aims to analyze the circadian behavior of the population of suprachiasmatic nucleus(SCN) neuron by light-dark cycle. Self-sustained oscillation is generated in individual SCN neuron by a molecular regulatory network. Cells oscillate with different periods, but the SCN neurons display significant synchronization under the effect of the light-dark(LD) cycle. We present a model for a population of circadian oscillations in the SCN. We show that synchronization can be entrained by a 24-h LD cycle. The results of this paper establish not only a theoretical foundation, but also a quantitative basis for understanding the essential cooperative dynamics.

In this paper, the control of energy resource chaotic system is investigated by timedelayed feedback control (TDFC) method. The controllability and the stability of the equilibriums of the system are verified. Several stabile periodic orbits are got in the numerical simulations, which shows the effectively of TDFC method.

Multiple compactons in a nonlinear atomic chain equations are studied. Atoms in the chain are interacted through first-and-second interactions. Nonlinearity in the evolution equation is set to be up to cubic polynomial. The spatial and temporal dependence of the solutions are given by separating method. Multiple N−site compactons are obtained.

In this paper, we present a class of interactional programming model (IPM) for the coexistence of competitions and cooperations problems, which can be regarded as decision making problems, such as supply chains. We introduce the optimal solution to the IPM, which is ideal and often does not exist. Therefore, we give a new concept of s-optimal solution, which always exists under some conditions....

In this paper, we consider a new algorithm for a generalized system for relaxed cocoercive nonlinear inequalities in Hilbert spaces by the convergence of projection methods. Our results extend and improve the recent ones announced by many others.
