Annotated imports
Presented simple extensions to scala language related to import statements: exported imports, which provide ability to reuse sequence of import clauses in composable form and default rewriters, which provide mechanism for pluggable macro-based AST transformation of overall compilation unit, activated by import of library object. Using these facilities not only allows more compact code, it preve...
متن کاملImports and Productivity
What is the effect of imports on productivity? To answer this question, we estimate a structural model of producers using product-level import data for a panel of Hungarian manufacturing firms from 1992 to 2001. In our model with heterogenous firms, producers choose to import or purchase domestically varieties of intermediate inputs. Imports affect firm productivity through expanding variety as...
متن کاملGem- And Co-Gem-Free Graphs Have Bounded Clique-Width
The P4 is the induced path of four vertices. The gem consists of a P4 with an additional universal vertex being completely adjacent to the P4, and the co-gem is its complement graph. Gemand co-gem-free graphs generalize the popular class of cographs (i. e. P4-free graphs). The tree structure and algebraic generation of cographs has been crucial for several concepts of graph decomposition such a...
متن کاملAre Exports and Imports Cointegrated
his study examined the long-run relationship between Nigerian exports and imports between 1960 and 2014. Exports and imports were disaggregated into oil and non-oil components. The application of the Johansen, Bound testing and the Hansen parameter instability test cointegration techniques revealed that Nigerian exports and imports at the aggregate and disaggregated level are cointegrated with ...
متن کاملGEM studies for LCTPC
The LCTPC collaboration is developing a time projection chamber (TPC) for a future linear collider. In the ILD concept for an ILC detector a TPC is foreseen as main tracking device. In order to get measurable signals on the anode, the primary electrons, produced by charged particles traversing the TPC, have to be multiplied. For this purpose gas electron multipliers (GEMs) can be used. Studies ...
