Analysis of the Sign of the Solution for Certain Second-Order Periodic Boundary Value Problems with Piecewise Constant Arguments

open access: yesMathematics, 2020
We find sufficient conditions for the unique solution of certain second-order boundary value problems to have a constant sign. To this purpose, we use the expression in terms of a Green’s function of the unique solution for impulsive linear periodic ...

Systematic conservation prioritization with the prioritizr R package

open access: yesConservation Biology, Volume 39, Issue 1, February 2025.
Abstract Plans for expanding protected area systems (prioritizations) need to fulfill conservation objectives. They also need to account for other factors, such as economic feasibility and anthropogenic land‐use requirements. Although prioritizations are often generated with decision support tools, most tools have limitations that hinder their use for ...

Sequencing vs. amplification for the estimation of allele dosages in sugarcane (Saccharum spp.)

open access: yesApplications in Plant Sciences, Volume 12, Issue 5, September-October 2024.
Abstract Premise Detecting single‐nucleotide polymorphisms (SNPs) in a cost‐effective way is fundamental in any plant breeding pipeline. Here, we compare three genotyping techniques for their ability to reproduce the allele dosage of SNPs of interest in sugarcane (Saccharum spp.).
