A Complete Characterization of Irreducible Cyclic Orbit Codes [PDF]

open access: yes, 2011
We give a complete list of orbit codes that are generated by an irreducible cyclic group, i.e. an irreducible group having one generator. We derive some of the basic properties of these codes such as the cardinality and the minimum distance.Comment: in ...

Universal multiplexable matK primers for DNA barcoding of angiosperms [PDF]

open access: yesApplications in Plant Sciences, 2016
Premise of the study:PCR amplification of the matK barcoding region is often difficult when dealing with multiple angiosperm families. We developed a primer cocktail to amplify this region efficiently across angiosperm diversity.Methods and Results:We developed 14 matK primers (seven forward, seven reverse) for multiplex PCR, using sequences available ...

Perturbation of transportation polytopes [PDF]

open access: yes, 2012
We describe a perturbation method that can be used to reduce the problem of finding the multivariate generating function (MGF) of a non-simple polytope to computing the MGF of simple polytopes.

Using matK sequence data to unravel the phylogeny of Casuarinaceae [PDF]

open access: yesMolecular Phylogenetics and Evolution, 2003
Casuarinaceae are a Gondwanic family with a unique combination of morphological characters not comparable to any other family. Until recently, the 96 species in the family were classified in a single genus, Casuarina s.l. A recent morphological revision of the family resulted in the splitting of Casuarina s.l.

Applicability of rbcL, matK, and trnK Regions in Identification of Scopellaria marginata (Blume) W.J.de Wilde & Duyfjes (Cucurbitaceae) [PDF]

open access: yesBrazilian Archives of Biology and Technology
East Java, Indonesia, has been identified as a new distribution area for Scopellaria marginata (Blume) W.J.de Wilde & Duyfjes (Cucurbitaceae) based on morphological evidence. To confirm this finding, molecular validation through DNA barcoding is required

Some more amplituhedra are contractible

open access: yes, 2019
The amplituhedra arise as images of the totally nonnegative Grassmannians by projections that are induced by linear maps. They were introduced in Physics by Arkani-Hamed \& Trnka (Journal of High Energy Physics, 2014) as model spaces that should provide ...
