Coordination Complexity [PDF]

open access: yesProceedings of the 2016 ACM Conference on Innovations in Theoretical Computer Science, 2016
We initiate the study of a quantity that we call coordination complexity. In a distributed optimization problem, the information defining a problem instance is distributed among $n$ parties, who need to each choose an action, which jointly will form a solution to the optimization problem.

Causal complexity demands community coordination

open access: yesBehavioral and Brain Sciences, 2021
Yarkoni’s argument risks skepticism about the very possibility of social science: If social phenomena are too causally complex, normal scientific methods could not possibly untangle them. We argue that the problem of causal complexity is best approached at the level of scientific communities and institutions, not the modeling practices of individual ...

Zn(II) coordination polymers: therapeutic activity and nursing application values against coronary heart disease

open access: yesDesigned Monomers and Polymers, 2022
In the current research, two coordination polymers (CPs) have been produced solvothermally on the basis of a semi-rigid multifunctional tricarboxylate, i.e., 5-(3,4-dicarboxylphenoxy) nicotic acid (H3L), and the chemical compositions of the two compounds
