In colliding beam facilities, the ""nal focus system" must demagnify the beams to attain the very small spot sizes required at the interaction points. The rst nal focus system with local chromatic correction was developed for the Stanford Linear Collider where very large demagniications were desired. This same conceptual design has been adopted by all the future linear col-lider designs as well...

In this paper, we discovered a new class of colliding key pairs of RC4, namely, two different secret keys generate the same internal state after RC4’s key scheduling algorithm. This is to our knowledge the first discovery of RC4 colliding keys with hamming distance greater than one, that is, the colliding key pairs we found can differ from each other at three different positions, and the value ...

classical trajectory (monte carlo) calculation is used to calculate collision rate constants of ion-quadrupolar molecule interactions for the h¯+c2h2 system. the method presented here takes into account the effect of the induced dipole-induced dipole potential on ion-quadrupolar molecule collision rate constants. it is also assumed that the colliding particles have a definite size. the thermal ...

In this paper we explore further the connections between convex bodies related to quantum correlation experiments with dichotomic variables and related bodies studied in combinatorial optimization, especially cut polyhedra. Such a relationship was established in Avis, Imai, Ito and Sasaki (J. Phys. A: Math. Gen. 38 10971–10987, 2005) with respect to Bell inequalities. We show that several well ...
