Factorization in Z[x]

Proceedings of the 2000 international symposium on Symbolic and algebraic computation, 2000
In this paper we describe ideas used to accelerate the Searching Phase of the Berlekamp--Zassenhaus algorithm, the algorithm most widely used for computing factorizations in $\ZZ[x]$. Our ideas do not alter the theoretical worst-case complexity, but they do have a significant effect in practice: especially in those cases where the cost of the Searching

Biochemistry of factor X

Blood Reviews, 1994
Factor X circulates as a serine protease which is converted to the active form at the point of convergence of the intrinsic and extrinsic coagulation pathways. Subsequently, the enzymatic species, factor Xa, is involved in macromolecular complex formation with its cofactor factor Va, a phospholipid surface and calcium to convert prothrombin into ...

The “X” Factor

2010
American science education is in trouble. As the United States continues to lag behind other nations in science achievement, the question is asked: how can we better get our students excited and inspired by science? This is the science teacher’s duty. The irony of the education profession is that some of the most important aspects of it are the hardest
