tion techniques, such as predictive deconvolution or Radon transforms, fail in the presence of complex structures. A technique popularized by the Delphi consortium offers an attractive alternative in 2-D because it is theoretically independent of subsurface structure and can therefore attack all surface-related multiples regardless of their complexity. The Delphi approach can be summarized by t...

Within the context of flux tube models, heavy quark fragmentation takes place through the breaking of flux tubes with the production of a (di)quarkanti(di)quark pair. It is found that the (di)quark produced are more likely to be found in an Lz = 0 state. This naturally leads to an supression of the polarization distribution parameters w3/2 and w̃1 for (D1,D ∗ 2) and (Λc1,Λ ∗ c1) production respe...

Big data and its applications have increasingly received interest by both scholars and practitioners. However, there is still missing evidence regarding how big data is understood as well as its applications in supply chain management (SCM). Empirical contributions are especially limited. This study seeks to address this gap through an explorative Delphi study to understand the terminology of b...
