A set of metrics is introduced to characterize the problem of vertical stability: the stability margin describes the plasma- wall interaction and the open-loop growth rate; the

In fact, even the tenfold reduction of m-aconitase concentration leads to the citrate-to-isocitrate ratio of 39 which is once again higher than observed in normal prostate cells

Upon formulation and numerical implementation of a model designed to demonstrate the effects of local particle size distribution effects in a porous asymmetric ceramic structure, it

An important part of the ECtHR's case law endorses human rights 'weighing and balancing' or, at least, what seems to amount to it (e.g. under the paragraphs 2 of Articles 8-11
