Different methods for treating the results of higher-order perturbative QCD calculations of the decay width of the Standard Model Higgs boson into bottom quarks are discusssed. Special attention is paid to the analysis of the $M_H$ dependence of the decay width $\Gamma(H\to \bar{b}b})$ in the cases when the mass of b-quark is defined as the running parameter in the $\bar{MS}$-scheme and as the...

For the vast majority of computations done both in pure and applied physics, ordinary 64-bit floating-point arithmetic (about 16 decimal digits) is sufficient. But for a growing body of applications, this level is not sufficient. For applications such as supernova simulations, climate modeling, n-body atomic structure calculations, "double-double" (approx. 32 digits) or even "quad-double"...

There are many ways to build a Storage Element. This talk surveys the common and popular architectures used to construct today's Storage Elements and presents points for consideration. The presentation then asks, "Are these architectures ready for LHC era experiments?". The answer may be surprising and certainly shows that the context in which they are used matters.
