Stack Sorting with Increasing and Decreasing Stacks [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2020
We introduce a sorting machine consisting of $k+1$ stacks in series: the first $k$ stacks can only contain elements in decreasing order from top to bottom, while the last one has the opposite restriction. This device generalizes the $\mathfrak{DI}$ machine introduced by Rebecca Smith, which studies the case $k=1$.

Some Properties of Generalized Topologies in GTSs

open access: yesCommunications in Advanced Mathematical Sciences, 2020
In this article, we introduce one new generalized topology and investigate its properties in a generalized topological space. Also, we give various properties of some generalized topologies defined in a generalized topological space.

Scientific Opinion on application (EFSA-GMO-NL-2010-77) for the placing on the market of herbicide-tolerant genetically modified cotton GHB614 × LLCotton25 for food and feed uses, import and processing under Regulation (EC) No 1829/2003 from Bayer CropScience [PDF]

open access: yesEFSA Journal, 2014
Cotton GHB614 × LLCotton25 was produced by conventional crossing. The EFSA GMO Panel previously assessed the two single cotton events GHB614 and LLCotton25 and did not identify safety concerns. Integrity of the inserts was retained in the two-event stack

Stratifying Quotient Stacks and Moduli Stacks [PDF]

open access: yes, 2018
Recent results in geometric invariant theory (GIT) for non-reductive linear algebraic group actions allow us to stratify quotient stacks of the form [X/H], where X is a projective scheme and H is a linear algebraic group with internally graded unipotent radical acting linearly on X, in such a way that each stratum [S/H] has a geometric quotient S/H ...

GA-stacking: Evolutionary stacked generalization [PDF]

open access: yesIntelligent Data Analysis, 2010
Stacking is a widely used technique for combining classifiers and improving prediction accuracy. Early research in Stacking showed that selecting the right classifiers, their parameters and the meta-classifiers was a critical issue. Most of the research on this topic hand picks the right combination of classifiers and their parameters.
