We consider an extention of a question of Erdős on the number of k-gons in a set of n points in the plane. Relaxing the convexity restriction we obtain results on 5-gons and 5-holes (empty 5-gons).

A simple parallel algorithm for decoding a Huuman encoded le is presented , exploiting the tendency of Huuman codes to resynchronize quickly in most cases. An extention to JPEG decoding is mentioned.

A parameter-free evaluation of the N −P11(1440) electromagnetic transition form factors is performed within a light-front constituent quark model, using for the first time the eigenfunctions of a mass operator which generates a large amount of configuration mixing in baryon wave functions. A one-body electromagnetic current, which includes the phenomenological constituent quark form factors alr...

In 2005, the U.S. Supreme Court held the death penalty unconstitutional as applied to juveniles in Roper v. Simmons. The Court reasoned that juveniles were less criminally culpable than adults because they lack maturity, they are more vulnerable to peer influence, and their character is not as well formed as that of adults. Although Roper addressed the imposition of the ultimate punishment of d...

For a locally compact group G, we prove that a topological inner invariant mean on LUC(G) has an extension to a topological inner invariant mean on L∞(G). Mathematics Subject Classification: 43A07, 43A10
