FROM DG-CATEGORIES OVER K TO K-LINEAR STABLE INFINITY-CATEGORIES
… prove that “idempotent- complete pretriangulated dg-categories over k are stable k-linear idempotent com- plete ∞-categories”. This result is a meeting point between algebraic topology and algebraic geometry. In 2013 L. Cohn proved it in a preprint, and in 2016, he updated the preprint to its …

Monte Carlo study of current variability in UTB SOI DG MOSFETs
The scaling of conventional silicon based MOSFETs is increasingly difficult into the nanometer regime due to short channel effects, tunneling and subthreshold leakage current. Ultra-thin body silicon-on-insulator based architectures offer a promising alternative, alleviating these problems through …

Purification and characterization of a poly(dG).poly(dC)-binding protein from Parenchinus angulosis
A poly(dG).poly(dC)-binding protein (suGF1) had previously been identified in sea urchin (Parenchinus angulosis) embryonic nuclear extracts (J.P. Hapgood, personal communication). suGF1 may be involved in the regulation of early histone gene expression by interaction with a nudeosome which has been …

Assesment of renewable energy resources and the impact of DG on power quality in distribution network
For many years, power systems were vertically operated; large power generation plants produced all of the electrical power. This kind of generation is often related to adequate geographical placement such as water sources, coal sources etc. The power is then transmitted towards large consumption …
