Expressed sequence tags (ESTs) from immune tissues of turbot (Scophthalmus maximus) challenged with pathogens
(BMC, 2008)Background: The turbot (Scophthalmus maximus; Scophthalmidae; Pleuronectiformes) is a flatfish species of great relevance for marine aquaculture in Europe. In contrast to other cultured flatfish, very few genomic resources ... 
Isoparametric hypersurfaces in Damek–Ricci spaces
(Elsevier, 20130601)We construct uncountably many isoparametric families of hypersurfaces in DamekRicci spaces. We characterize those of them that have constant principal curvatures by means of the new concept of generalized Kähler angle. ... 
Embedding Theorems for the Dunkl Harmonic Oscillator on the Line
(National Academy of Science of Ukraine, 2014)Embedding results of Sobolev type are proved for the Dunkl harmonic oscillator on the line. 
A Perturbation of the Dunkl Harmonic Oscillator on the Line
(National Academy of Science of Ukraine, 2015)Let Jσ be the Dunkl harmonic oscillator on R (σ>−1/2. For 0<u<1 and ξ>0, it is proved that, if σ>u−1/2, then the operator U=Jσ+ξx−2u, with appropriate domain, is essentially selfadjoint in L2(R,x2σdx), the Schwartz ... 
Whole genome sequencing of turbot (Scophthalmus maximus; Pleuronectiformes): A fish adapted to demersal life
(Oxford University Press, 2016)The turbot is a flatfish (Pleuronectiformes) with increasing commercial value, which has prompted active genomic research aimed at more efficient selection. Here we present the sequence and annotation of the turbot genome, ... 
Exploring the topological sources of robustness against invasion in biological and technological networks
(Nature Publishing Group, 20160210)For a network, the accomplishment of its functions despite perturbations is called robustness. Although this property has been extensively studied, in most cases, the network is modified by removing nodes. In our approach, ... 
Vaccineinduced modulation of gene expression in turbot peritoneal cells. A microarray approach
(Elsevier, 20160622)We used a microarray approach to examine changes in gene expression in turbot peritoneal cells after injection of the fish with vaccines containing the ciliate parasite Philasterides dicentrarchi as antigen and one of ... 
HGalois extensions with normal basis for weak Hopf algebras
(International Electronic Journal of Algebra, 2017)Let H be a weak Hopf algebra and let A be an Hcomodule algebra with subalgebra of coinvariants AH. In this paper we introduce the notion of HGalois extension with normal basis and we prove that AH ,→ A is an HGalois ... 
The group of strong Galois objects associated to a cocommutative Hopf quasigroup
(Korean Mathematical Society, 2017)Let H be a cocommutative faithfully flat Hopf quasigroup in a strict symmetric monoidal category with equalizers. In this paper we introduce the notion of (strong) Galois Hobject and we prove that the set of isomorphism ... 
Suppressors of selection
(Public Library of Science, 201707)Inspired by recent works on evolutionary graph theory, an area of growing interest in mathematical and computational biology, we present examples of undirected structures acting as suppressors of selection for any fitness ... 
A method for validating Rent’s rule for technological and biological networks
(Springer Nature, 20170714)Rent’s rule is empirical power law introduced in an effort to describe and optimize the wiring complexity of computer logic graphs. It is known that brain and neuronal networks also obey Rent’s rule, which is consistent ... 
Evolutionary regime transitions in structured populations
(PLOS, 2018)The evolutionary dynamics of a finite population where resident individuals are replaced by mutant ones depends on its spatial structure. Usually, the population adopts the form of an undirected graph where the place ... 
Applications of PDEs to the study of affine surface geometry
(Mathematical Society of Serbia, 2019)If M=(M,∇) is an affine surface, let Q(M):=ker(H+1m−1ρs) be the space of solutions to the quasiEinstein equation for the crucial eigenvalue. Let M~=(M,∇~) be another affine structure on M which is strongly projectively ... 
New insights into the Manila clam – Perkinsus olseni interaction based on gene expression analysis of clam hemocytes and parasite trophozoites through in vitro challenges
(Elsevier, 2020)The Manila clam (Ruditapes philippinarum) is the bivalve species with the highest global production from both fisheries and aquaculture, but its production is seriously threatened by perkinsosis, a disease caused by the ... 
Codimension one Ricci soliton subgroups of solvable Iwasawa groups
(Elsevier, 2021)Recently, Jablonski proved that, to a large extent, a simply connected solvable Lie group endowed with a leftinvariant Ricci soliton metric can be isometrically embedded into the solvable Iwasawa group of a noncompact ...
