Why Is Consumption Less Volatile Than Income?

Rank-width is less than or equal to branch-width

We prove that the rank-width of the incidence graph of a graph G is either equal to or exactly one less than the branch-width of G, unless the maximum degree of G is 0 or 1. This implies that rank-width of a graph is less than or equal to branch-width of the graph unless the branch-width is 0. Moreover, this inequality is tight.

Women’s Education and World Peace: A Feminist Dream Comes True; Comment on “The Pill Is Mightier Than the Sword”

This commentary on Potts et al provides a critical view on their thesis that increasing the level of education among women is likely to reduce terrorism.

Artificial Dielectrics Having Refractive Indices Less than Unity

Two types of artificial dielectric are examined; the first consists of an array of conducting rods and the second of a set of parallel conducting plates having perforations in the form of circular holes. Both these media are designed to operate for an incident electromagnetic wave, which is polarized so that its electric field is parallel to the conducting elements. It is found that the effecti...
