Spatial abstraction empowers complex agent control processes. We propose a formal definition of spatial abstraction and classify it by its three facets, namely aspectualization, coarsening, and conceptual classification. Their characteristics are essentially shaped by the representation on which abstraction is performed. We argue for the use of so-called aspectualizable representations which en...

Transfer entropy (TE) has proven to be an effective tool for determining the causal connection between two processes. For example, TE been used classify leader and follower agents in collective dynamics Vicsek model (VM). However, previous results have limited interaction radii, which are precisely same among all agents, is not realistic practice. Here, we propose a modified version of VM where...

This paper considers a pure exchange stochastic overlapping generations model in which agents live for two periods. At each date, either a young or an old agent has larger endowments than the other, which is stochastically determined. In addition to the uncertainty, commitment cannot be externally enforced in this economy. In this environment, I suggest a transfer rule from a young agent to an ...

A selective divalent chain transfer agent is designed to exclusively lead polyolefin growth on a pentanediyl moiety via coordinative polymerization (CCTP).
