... in that case. One can also define magic N- dimensional cubes (also known as magic N- cubes) in a similar way to that given in Definition 1.1 and the reader is invited to provide the definition herself, ... construction of a remarkable class of magic N- cubes, was the introduction ( [ A- L], p. 624) of an operation on the set of all magic squares. This operation is associative and...

... plane as the plane z = 1 in R 3 , and form an arrangement ˆ A that has, for each line  of the arrangement A, a plane through  and the origin. If A contains the line at infinity, add correspondingly ... partial cubes. In addition, many additional sporadic examples of simplicial pseudoline arrangements are known. 6 Geometric representation and non-arrangement-based partial cubes In an...

... low-energy region, the magnetic barrier can suppress the electron transmission probability for any in- cident angles, and thus lead to vanished conductances. The conductance increases as the Spin-related ... change when the barrier changes from transparent to opaque. These quantities are what experimentalists can actually measure. 4. Conclusion In summary, we investigated theoretically quantu...
