Abstract

Let A be the incidence matrix of lines and points of the classical projective plane PG(2, q) with q odd. With respect to a conic in PG(2, q), the matrix A is partitioned into 9 submatrices. The rank of each of these submatrices over F~q~, the defining field of PG(2, q), is determined. Β© 2010 Wiley Periodicals, Inc. J Combin Designs 18: 224–236, 2010

## Abstract In a previous paper 1, all point sets of minimum size in __PG__(2,__q__), blocking all external lines to a given irreducible conic ${\cal C}$, have been determined for every odd __q__. Here we obtain a similar classification for those point sets of minimum size, which meet every externa

## Abstract Several studies have shown that HER‐2/neu (erbB‐2) blocking therapy strategies can cause tumor remission. However, the responsible molecular mechanisms are not yet known. Both ERK1/2 and Akt/PKB are critical for HER‐2‐mediated signal transduction. Therefore, we used a mouse tumor model
