... solution. Moreover, the set of optimal solutions of the two prob- lems coinside. The following assertion gives a sufficient condition for the existence of optimal solutions. 162 Nguyen Khoa Son and ... < 1. If the compact basis V b of the polyhedron V = {F : A − BF ≥ 0} consists of only one point F ∗ then either F 0 =0or F ∗ is the unique optimal solution for Problem...

... locking. If the incident electrons are spin polarized along the direction of the vector (π × z), the magnetic field bends the trajectory of the electrons, resulting in a rotation of the spin of the transmitted ... demonstrate that the magnetic field of the magnetic barrier bends the trajectory of the electrons, and therefore rotate the spin. 2. Theory Firs...

We note that the distribution of P K2’s predictions were most like those of the actual senses. 4 Conclusions This paper shows how to use clustering criterion functions as a means of automatically ... measure is based on (Mojena, 1977), which finds clustering solutions for all values of k from 1 N , and then determines the mean and standard deviation of the criterion functio...

... a IIb 265–284 were the most effective antagonists of platelet aggregation. To gain further insight into the fibrinogen-recognition sites of a IIb , we evaluated the inhibitory effect of the above peptides on ... platelet activation. The rationale of this study was based on the assumption that peptide fragments derived from the a IIb subunit could act as inhibitors of...
