Chemical copying of connectivity

Eccentric Connectivity Index of Chemical Trees

The eccentric connectivity index ξ is a distance–based molecular structure descriptor that was recently used for mathematical modeling of biological activities of diverse nature. We prove that the broom has maximum ξ among trees with a fixed maximum vertex degree, and characterize such trees with minimum ξ . In addition, we propose a simple linear algorithm for calculating ξ of trees.

Reachability, Connectivity, and Proximity in Chemical Spaces

A chemical universe consists of a set X of chemical compounds and a set of reactions between them. Each reaction transforms a finite (small) set of educts in a small set of products. Reactions thus form directed hyperedges on X. Since X can be infinite, it is of interest to consider X not only for a combinatorial point of view but also as a topological construct. Here we argue that generalized ...

Beyond Copying

Smart copying

Can imitation be considered one of the most successful strategies in business? My answer is " yes ". It appears that this topic is getting more and more attention nowadays. It is well known that Apple's success can be attributed to taking existing ideas and repackaging them with excellent design. However, no one can readily blame Steven Jobs for lacking originality. Even if the ideas for his co...

Copying Behaviour of Expressive Motion

In this paper we present an agent that can analyse certain human fullbody movements in order to respond in an expressive manner with copying behaviour. Our work focuses on the analysis of human full-body movement for animating a virtual agent, called Greta, able to perceive and interpret users’ expressivity and to respond properly. Our system takes in input video data related to a dancer moving...
