An Eulerian circuit in a directed graph is one of the most fundamental Graph Theory notions. Detecting if G has unique can be done polynomial time via BEST theorem by de Bruijn, van Aardenne-Ehrenfest, Smith and Tutte (1941–1951) [15], [16] (involving counting arborescences), or tailored characterization Pevzner, 1989 computing intersection simple cycles G), both which thus rely on overly compl...

There are many indicators to suggest that Americans feel technology is complicating their lives. These range from the growing strength of the voluntary simplicity movement [Elgin 1998] and the slew of popular books on “unplugging” [Brende 2004] to research showing that many consumers are overwhelmed by the increasing complexity of daily living [Breen-Pierce & Robin 2000]. In response, many indi...

1 Abstract: A Steiner bundle E on P n has a linear resolution of the form 0 → O(−1) s →O t → E → 0. In this paper we prove that a generic Steiner bundle E is simple if and only if χ(End E) is less or equal to 1. In particular we show that either E is exceptional or it satisfies the inequality t ≤ n+1+ √ (n+1) 2 −4 2 s.

Firstly, in this paper, we prove that the equivalence of simplicity and the symmetry of forking. Secondly, we attempt to recover deenability part of stability theory to simplicity theory. In particular, using elimination of hyperimaginaries we prove that for any supersimple T , canonical base of an amalgamation class P is the union of names of-deenitions of P, ranging over stationary L-formulas...

Diacylglycerol (DAG) has unique functions as a basic component of membranes, an intermediate in lipid metabolism and a key element in lipid-mediated signaling. In eukaryotes, for example, impaired DAG generation and/or consumption have severe effects on organ development and cell growth associated with diseases such as cancer, diabetes, immune system disorders and Alzheimer's disease. Although ...
