In this paper, we prove that for the oper stratification of de Rham moduli space $M_{\mathrm{dR}}(X,r)$, closed stratum is unique minimal with dimension $r^2(g-1)+g+1$, and open dense consisting irreducible flat bundles stable underlying vector maximal stratum.

Surrogate-based optimization (Queipo et al. 2005, Simpson et al. 2008) represents a class of optimization methodologies that make use of surrogate modeling techniques to quickly find the local or global optima. It provides us a novel optimization framework in which the conventional optimization algorithms, e.g. gradient-based or evolutionary algorithms are used for sub-optimization(s). Surrogat...

Proxies of mate value must be evolutionarily salient. Gangestad & Simpson (G&S) have made a good case that fluctuating asymmetry is an important proxy of male mate value that correlates well with genetic and developmental quality. The use of financial variables as proxies for male investment ability by Gangestad, Simpson, and virtually every other investigator of human mating in evolutionary pe...

Coming on the heels of the publication of Tobacco Control’s Twentieth Anniversary issue (vol. 21, issue 2) comes another landmark: David Simpson is stepping down from his longtime position as editor for the journal’s News Analysis section, which he has held since shortly after the journal’s founding in 1992. Mr Simpson’s contributions to tobacco control are legion. Many across the globe, includ...
