Sixteen New Linear Codes With Plotkin Sum
Sixteen new linear codes are presented: three of them improve the lower bounds on the minimum distance for a linear code and the rest are an explicit construction of unknown codes attaining the lower bounds on the minimum distance. They are constructed using the Plotkin sum of two linear codes, also called (u|u + v) construction. The computations have been achieved using an exhaustiv search.
متن کاملSixteen days.
When does a human being begin to exist? We argue that it is possible, through a combination of biological fact and philosophical analysis, to provide a definitive answer to this question. We lay down a set of conditions for being a human being, and we determine when, in the course of normal fetal development, these conditions are first satisfied. Issues dealt with along the way include: modes o...
متن کاملNew Perspectives on Yang-Mills Theories With Sixteen Supersymmetries
We describe various approaches that give matrix descriptions of compactified NS fivebranes. As a result, we obtain matrix models for Yang-Mills theories with sixteen supersymmetries in dimensions 2, 3, 4 and 5. The equivalence of the various approaches relates the Coulomb branch of certain gauge theories to the moduli space of instantons on T. We also obtain an equivalence between certain six-d...
متن کاملNew Type II String Theories With Sixteen Supercharges
We present two new backgrounds of type IIA string theory preserving 16 supercharges. One is a Wilson line for (−1)LS and the other is an orbifold by a reflection of four coordinates, along with the action of (−1)LS , where FLS is left-moving spacetime fermion number. The Wilson line theory has many new phenomena, including a self-duality of type IIA on a single circle, enhanced gauge symmetry a...
متن کاملIdentification of sixteen new galactocerebrosides from the starfish Protoreaster nodosus.
Twenty-one galactocerebrosides (1-21), including sixteen new compounds (3-7, 9-17, 19, 21), were identified from a cerebroside molecular species obtained from the chloroform/methanol extract of pyloric caeca dissected from the starfish Protoreaster nodosus. The structures of these galactocerebrosides were determined on the basis of chemical and spectroscopic evidences. Especially, one-pot GC-MS...
