Summary In this paper, the resource allocation problems of multiagent systems are investigated. Different from well‐studied problems, dynamics agents taken into account in our problem, which results that problem could not be solved by most existing algorithms. Here, form second‐order dynamics, causes difficulties designing and analyzing distributed Based on gradient descent state feedback, two algorithms proposed to achieve optimal allocation, their convergence analyzed constructing suitable...
To increase the variety and security of communication, we present definitions modified projective synchronization with complex scaling factors (CMPS) real chaotic systems systems, where establish a link between chaos chaos.

Complex intracellular organizations are commonly represented by dividing the metabolic process of cells into different organelles. Therefore, identifying sub-cellular organelle architecture is significant for understanding structural properties, specific functions, and biological processes in cells. However, discrimination these structures natural organizational environment their functional consequences not clear. In this article, we propose a new pixel-level multimodal fusion (PLMF) deep...
