The C++ standard has always forbidden containers of const elements (such as vector<const T> or set<const T>). Visual Studio 2013 and earlier accepted such containers. In the current version, such containers fail to compile. std::allocator::deallocate In Visual Studio 2013 and earlier, std::...
. The hadronization is achieved including a\bar{q} qpair with the quantum numbers of the vacuum. Concerning flavor space, we denote\bar{q} q \equiv \sum _{i} \bar{q}_i q_i(i=\left\{ u,d,s\right\}). Then, since we want to get a pseudoscalar meson and a vector, we ...
C++ 标准始终禁止 const 元素(如 vector<const T> 或set<const T>)的容器。 Visual Studio 2013 及更早版本接受此类容器。 在当前版本中,此类容器无法编译。 std::allocator::deallocate 在Visual Studio 2013 和早期版本中,std::allocator::deallocate(p, n) 忽略了传入用于 n 的参数。 C++ 标准始终要求 n...
The flavor-violating decay of a new neutral massive gauge bosonis analyzed in the context of extended models, in which this particle emerges. By means of the analysis of thedecay,conversion process in nuclei and thedecay, the strength of thecoupling is estimated and used to calculate the branc...
As an application of this result we show, in particular, that the second jet of a holomorphic vector field defined on a compact complex manifold M of dimension 3 cannot vanish at an isolated singular point provided that M carries more than a single holomorphic vector field....
The PHF2-C23A group also showed dramatically reduced tumor growth than the Vector/ND group. The PHF2-C23A group did not exhibit noticeable effect on tumor growth when exposed to PAD feeding (Fig. 5b–d, lanes 5–6). This result indicates that the degradation of PHF2 protein, a result ...
