Based on the charge independence hypothesis the properties of V particles are theoretically investigated. It is found that the curious behaviours of these unstable particles are most simply interpreted in terms of the 1}-charge conservation law which directly results from the C. I. hypothesis and suitable isotopic spin assignments to these particles. The topics which are discussed in this paper...

There is a large gap between Zhang’s theoretical bound for the length n of a binary extremal self-dual doublyeven code and what we can construct. The largest n is 136. In order to find examples for larger n a non-trivial automorphism group might be helpful. In the list of known examples extended quadratic residue codes and quadratic double circulant codes have large automorphism groups. But in ...

Dynamic optimization of computer programs can dramatically improve their performance on a variety of applications. This paper presents an efficient infrastructure for dynamic recompilation that can support a wide range of dynamic optimizations including profile-driven optimizations. The infrastructure allows any section of code to be optimized and regenerated on-the-fly, even code for currently...

Even-cycle matroids are elementary lifts of graphic and even-cut cographic matroids. We present a polynomial algorithm to check if binary matroid is an even-cycle we matroid. These two algorithms rely on (to be described in pair follow-up papers) pinch-graphic.

The even-even Ytterbium isotopes lack spectroscopic information with the increase of neutron number and they are well deformed nuclei, presenting rotational properties. In this mass region nuclear chart predictions have shown rare phenomena related to structure, such as shape coexistence. work population excited states were investigated in Yb via 2n-transfer reaction 168-174Yb (18O, 16O) 170-17...
