在羊群行为研究领域,关于信息瀑布的相关研究已经从理性和非理性的层面阐述了对于信号或行为的羊群效应的形成过程。然而,上述模型均基于严格的假设,如完全理性,而这与现实生活相去甚远。通过两个子模型建立一个真实市场的模拟环境以移除强假设,并以进化博弈理论的方法阐述在行为可观察(PAO)及信号可观察(PSO)情形下羊群行为的形成。结果发现,羊群行为在实物投资情形下是自我实现的,当资产价格是内生而没有固定的确定价值时羊群行为不会自发产生。此外,内生价格变化方向是由信息发布者的市场影响力决定的。

采用对氨基苯磺酸对氧化石墨烯(GO)进行表面功能化,进而负载贵金属Pd,解决了Pd团聚和不易在载体表面负载的问题,从而提高了Pd基催化剂对于甲酸的催化能力。实验研究了相同实验条件下,Pd在氧化石墨烯、还原石墨烯(RGO)和磺化处理的石墨烯(SGO)表面的分散和负载量以及得到的复合催化剂的催化性能。实验结果表明,SGO更容易负载贵金属,得到的催化剂对O2气的电催化还原能力优于Pd/GO和Pd/RGO,此外Pd/SGO催化剂对CO的耐受力也明显提升,这可能是苯环上的π-π键和—SO3H的范德华力协同作用更有利于Pd的固定与分散。对Pd/SGO催化氧还原的机理也进行了分析,该氧还原为2电子反应过程。

This paper focuses on the online distributed optimization problem based on multi-agent systems. In this problem, each agent can only access its own cost function and a convex set, and can only exchange local state information with its current neighbors through a time-varying digraph. In addition, the agents do not have access to the information about the current cost functions until decisions are made. Different from most existing works on online distributed optimization, here we consider the case where the cost functions are strongly pseudoconvex and real gradients of the cost functions are not available. To handle this problem, a random gradient-free online distributed algorithm involving the multi-point gradient estimator is proposed. Of particular interest is that under the proposed algorithm, each agent only uses the estimation information of gradients instead of the real gradient information to make decisions. The dynamic regret is employed to measure the proposed algorithm. We prove that if the cumulative deviation of the minimizer sequence grows within a certain rate, then the expectation of dynamic regret increases sublinearly. Finally, a simulation example is given to corroborate the validity of our results.
