AMERICANS REMEMBER the presidential election of 1988 as the Willie Horton election. A young black man convicted of murder and sentenced to life in a Massachusetts prison, Horton escaped while on furlough and assaulted a white couple in their home, raping the woman. George Bush made Horton a household name by repeatedly mentioning Horton’s story and pinning the blame on his Democratic opponent, ...

There are some points in the reply of Horton et al. [3] to my comment [2] on their paper [1] which I cannot let stand without a response. I provide here some clarification of how much I proved about the set of points where their law of motion is ill-defined. In a recent article in J. Phys. A [1], Horton et al. present what they claim is a Bohm-type law of motion for point particles, based on a ...

The Horton and Tokunaga branching laws provide a convenient framework for studying self-similarity in random trees. The Horton self-similarity is a weaker property that addresses the principal branching in a tree; it is a counterpart of the power-law size distribution for elements of a branching system. The stronger Tokunaga self-similarity addresses so-called side branching. The Horton and Tok...

In 1978 Erdős asked if every sufficiently large set of points in general position in the plane contains the vertices of a convex k-gon, with the additional property that no other point of the set lies in its interior. Shortly after, Horton provided a construction—which is now called the Horton set—with no such 7-gon. In this paper we show that the Horton set of n points can be realized with int...

Horton, Alderman and Rivera (in press) address the challenge of hunger and malnutrition, as done earlier by Behrman, Alderman and Hoddinott (2004) for the 2004 Copenhagen consensus. Horton, Alderman and Rivera (in press) state their work “builds on and updates” the earlier work. There are differences in approach between these two analyses. Four opportunities are proposed by Behrman, Alderman an...
