the set of binary necklaces of a certain length. We further investigate the stability of a periodic orbit. Specifically, we perturb a state in the periodic orbit by changing the value of a single entry of the state. The trajectory, with the perturbed state being the initial condition, will enter another (possibly the same) periodic orbit in finite time steps. We then provide a complete characterization of all such transitions from one periodic orbit to another. In particular, we construct a digraph, with the vertices being the periodic orbits, and the (directed) edges representing the transitions among the orbits. We call such a digraph the stability structure of the conjunctive Boolean network.'

-any other, members have begun to focus
on the Internet as well as the more traditional telecom markets. Though
the vast majority of Internet-related bills introduced in the last two
years have failed to stand up to the
close scrutiny of hearings and committee debates known as markups, that
isn't stopping the failed bills' sponsors from trying to attach them to
spending bills.

"There are a lot of telecom riders this year," said one Senate staffer, "but then again there were a lot of telecom and Internet bills introduced, too." Riders are bills attached to spending packages.

Sen. John McCain, R-Ariz. and chairman of the Commerce Committee, had
been unable to move his bill requiring schools and libraries receiving
federal funding for technology to obtain at their cost filtering equipment
to protect children online. So this summer he successfully
