Genetic resources of perennial forage grasses in Serbia: Current state, broadening and evaluation [PDF]

open access: yesSelekcija i Semenarstvo, 2017
Due to historical background of vegetation development, geographical position, climate and relief, Serbia represents one of the 158 world biodiversity centres, based upon the number of plant species and territory size (biodiversity index 0.72).

Strictly positive definite functions on compact abelian groups

open access: yes, 2010
We study the Fourier characterisation of strictly positive definite functions on compact abelian groups. Our main result settles the case $G = F \times \mathbb{T}^r$, with $r \in \mathbb{N}$ and $F$ finite.

Characterisation of cylindrical curves [PDF]

open access: yes, 2015
We employ moving frames along pairs of curves at constant separation to derive various conditions for a curve to belong to the surface of a circular ...

Observation and Distinction. Representing Information in Infinite Games [PDF]

open access: yes, 2020
We compare two approaches for modelling imperfect information in infinite games by using finite-state automata. The first, more standard approach views information as the result of an observation process driven by a sequential Mealy machine. In contrast,

A comparative molecular and 3-dimensional structural investigation into cross-continental and novel avian Trypanosoma spp. in Australia

open access: yesParasites & Vectors, 2017
Background Molecular and structural information on avian Trypanosoma spp. throughout Australia is limited despite their intrinsic value in understanding trypanosomatid evolution, diversity, and structural biology. In Western Australia tissue samples (n =

A geometric characterisation of Desarguesian spreads

open access: yes, 2017
We provide a characterisation of $(n-1)$-spreads in $\mathrm{PG}(rn-1,q)$ that have $r$ normal elements in general position. In the same way, we obtain a geometric characterisation of Desarguesian $(n-1)$-spreads in $\mathrm{PG}(rn-1,q)$, $r>2$

G-Deformations of maps into projective space [PDF]

open access: yes, 2017
$G$-deformability of maps into projective space is characterised by the existence of certain Lie algebra valued 1-forms. This characterisation gives a unified way to obtain well known results regarding deformability in different geometries.Comment: 16 ...

The Joseph ideal for $\mathfrak{sl}(m|n)$

open access: yes, 2016
Using deformation theory, Braverman and Joseph obtained an alternative characterisation of the Joseph ideal for simple Lie algebras, which included even type A.

Knot commensurability and the Berge conjecture [PDF]

open access: yes, 2011
We investigate commensurability classes of hyperbolic knot complements in the generic case of knots without hidden symmetries. We show that such knot complements which are commensurable are cyclically commensurable, and that there are at most $3 ...

Experimental Continuous Casting of Nitinol

open access: yesMetals, 2020
Commercially available nitinol is currently manufactured using classic casting methods that produce blocks, the processing of which is difficult and time consuming.
