Characterizations of Transversal and Fundamental Transversal Matroids [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2011
A result of Mason, as refined by Ingleton, characterizes transversal matroids as the matroids that satisfy a set of inequalities that relate the ranks of intersections and unions of nonempty sets of cyclic flats. We prove counterparts, for fundamental transversal matroids, of this and other characterizations of transversal matroids.

Comparison of 6 DNA extraction methods for isolation of high yield of high molecular weight DNA suitable for shotgun metagenomics Nanopore sequencing to detect bacteria

open access: yesBMC Genomics, 2023
Background Oxford Nanopore Technologies (ONT) offers an accessible platform for long-read sequencing, which improves the reconstruction of genomes and helps to resolve complex genomic contexts, especially in the case of metagenome analysis.

Transversal Harm, Regulation, and the Tolerance of Oil Disasters [PDF]

open access: yes, 2022
Law, through regulation, criminalization and litigation, provides key mechanisms for mitigating the harmful effects of oil disasters. At the same time, these mechanisms also enable the perpetuation of oil disasters under an extractivist imperative.

Development of a portable on-site applicable metagenomic data generation workflow for enhanced pathogen and antimicrobial resistance surveillance

open access: yesScientific Reports, 2023
Rapid, accurate and comprehensive diagnostics are essential for outbreak prevention and pathogen surveillance. Real-time, on-site metagenomics on miniaturized devices, such as Oxford Nanopore Technologies MinION sequencing, could provide a promising ...

Transversals in Trees [PDF]

open access: yesJournal of Graph Theory, 2012
A transversal in a rooted tree is any set of nodes that meets every path from the root to a leaf. We let c(T,k) denote the number of transversals of size k in a rooted tree T. We define a partial order on the set of all rooted trees with n nodes by saying that a tree T succeeds a tree T' if c(T,k) is at least c(T',k) for all k and strictly greater than

Corrigendum to: Independent Transversal Domination in Graphs [Discuss. Math. Graph Theory 32 (2012) 5–17]

open access: yesDiscussiones Mathematicae Graph Theory, 2022
In [Independent transversal domination in graphs, Discuss. Math. Graph Theory 32 (2012) 5–17], Hamid claims that if G is a connected bipartite graph with bipartition {X, Y } such that |X| ≤ |Y| and |X| = γ(G), then γit(G) = γ(G) + 1 if and only if every ...

A shotgun metagenomics approach to detect and characterize unauthorized genetically modified microorganisms in microbial fermentation products

open access: yesFood Chemistry: Molecular Sciences, 2021
The presence of a genetically modified microorganism (GMM) or its DNA, often harboring antimicrobial resistance (AMR) genes, in microbial fermentation products on the market is prohibited by European regulations.

Methods and tools for assessing transversal skills [PDF]

open access: yes, 2022
This Methodological Guide has been prepared to offer different strategies for the development of transversal skills (TS) of students (including critical and creative thinking, interpersonal/socioemotional and citizen-oriented skills, and learning to ...

TRANSVERSITY [PDF]

open access: yesTransversity 2005, 2006
Some general remarks on parton transverse spin distributions and transverse motions are presented. The issue of accessing experimental information on the transversity distributions h_1^q is discussed. In particular direct information could be obtained from Drell-Yan processes with polarized protons and antiprotons (planned at GSI), while indirect ...
