Habenula and ADHD: Convergence on time [PDF]
Attention deficit/hyperactivity disorder (ADHD) is a childhood-onset psychiatric condition characterized by hyperactivity, impulsivity, and attention deficit. In addition to these core symptoms, accumulating evidence suggests that ADHD may also involve alterations in circadian rhythms, sleep disturbance, and time perception.

Convergence of space and time through GIS [PDF]
Human's exploration of space has changed over time, depending on the expansion of the limits of his knowledge. Space is infinite, but it is limited by the possibility of human knowledge. The original man knew very little about the space in which

Graph-Based Generalization of Galam Model: Convergence Time and Influential Nodes
We study a graph-based generalization of the Galam opinion formation model. Consider a simple connected graph which represents a social network. Each node in the graph is colored either blue or white, which indicates a positive or negative opinion on a ...
