Could Plant Hormones Provide a Reliable Tool for Early Detection of Rhynchophorus ferrugineus (Coleóptera: Curculionidae) Infested Palms?
(Entomological Research Society, 2019-03)
Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae) is one of the most important pest of palms worldwide. A serious management problem is the difficulty of detecting early infestation stages, which is critical ...
Eliahou number, Wilf function and concentration of a numerical semigroup
(Taylor & Francis, 2022-03-30)
We give an estimate of the minimal positive value of the Wilf function of a numerical semigroup in terms of its concentration. We describe necessary conditions for a numerical semigroup to have a negative Eliahou number ...
Exponential Perturbative Expansions and Coordinate Transformations
(MDPI, 2020)
We propose a unified approach for different exponential perturbation techniques used in
the treatment of time-dependent quantum mechanical problems, namely the Magnus expansion,
the Floquet–Magnus expansion for periodic ...
Using videos to improve oral presentation skills in distance learning engineering master's degrees
(Taylor & Francis, 2019-09-11)
In this paper we present a pilot study to improve the learning process on distance learning Engineering master's degrees. We propose an activity where the students individually produce a video in which they explain the ...
On the generalization of the construction of quantum codes from Hermitian self-orthogonal codes
(Springer, 2022-03-21)
Many q-ary stabilizer quantum codes can be constructed from Hermitian self-orthogonal q2-ary linear codes. This result can be generalized to q2m-ary linear codes, m>1. We give a result for easily obtaining quantum codes ...
Efficient time integration methods for Gross-Pitaevskii equations with rotation term
(American Institute of Mathematical Sciences, 2019)
The objective of this work is the introduction and investigation of favourable time integration methods for the Gross-Pitaevskii equation with rotation term. Employing a reformulation in rotating Lagrangian coordinates, ...
Singular perturbations of Blaschke products and connectivity of Fatou components
(American Institute of Mathematical Sciences (AIMS), 2017)
The goal of this paper is to study the family of singular perturbations of Blaschke products given by Ba,λ(z)=z3z−a1−a¯z+λz2. We focus on the study of these rational maps for parameters a in the punctured disk D∗ and |λ| ...
Splitting and composition methods with embedded error estimators
(Elsevier, 2019-12)
We propose new local error estimators for splitting and composition methods. They are based on the construction of lower order schemes obtained at each step as a linear combination of the intermediate stages of the integrator, ...
Phase portraits of Abel quadratic differential systems of the second kind
(Taylor & Francis, 2018)
We provide normal forms and the global phase portraits on the Poincaré
disk of some Abel quadratic differential equations of the second kind. Moreover, we also
provide the bifurcation diagrams for these global phase portraits.
Highly tempering infinite matrices
(Springer Milan, 2017-02)
In this short note, it is proved the existence of in nite matrices that
not only preserve convergence and limits of sequences but also convert every mem-
ber of some dense vector space consisting, except for zero, of ...
