    • A probabilistic analysis of a discrete-time evolution in recombination 
      Martínez Aguilera, Servet (Elsevier, 2017)
      We study the discrete-time evolution of a recombination transformation in population genetics. The transformation acts on a product probability space, and its evolution can be described by a Markov chain on a set of ...
    • A stationary distribution associated to a set of laws whose initial states are grouped into classes. an ... 
      Martínez Aguilera, Servet (Cambridge Univ Press, 2016)
      Let I be a finite set and S be a nonempty strict subset of I which is partitioned into classes, and let C(s) be the class containing s is an element of S. Let (P-s : s is an element of S) be a family of distributions on ...
    • Additive representation of symmetric inverse M-matrices and potentials 
      Dellacherie, Claude; Martínez Aguilera, Servet; San Martín Aristegui, Jaime (Academic Press-Elsevier, 2016)
      In this article we characterize the closed cones respectively generated by the symmetric inverse M-matrices and by the inverses of symmetric row diagonally dominant M-matrices. We show the latter has a finite number of ...
    • Calcium/calmodulin-dependent protein kinase type IV Is a target gene of the Wnt/β-catenin signaling pathway 
      Arrázola, Macarena S.; Varela Nallar, Lorena; Colombres, Marcela; Toledo, Enrique M.; Cruzat, Fernando; Pavez, Leonardo; Assar, Rodrigo; Aravena, Andrés; González, Mauricio; Montecino, Martín; Maass Sepúlveda, Alejandro; Martínez Aguilera, Servet; Inestrosa, Nibaldo C. (2009)
      Calcium/calmodulin-dependent protein kinase IV (CaMKIV) plays a key role in the regulation of calcium-dependent gene expression. The expression of CaMKIV and the activation of CREB regulated genes are involved in memory ...
    • Codon usage bias reveals genomic adaptations to environmental conditions in an acidophilic consortium 
      Hart, Andrew; Cortés, Maria Paz; Latorre, Mauricio; Martínez Aguilera, Servet (Public Library Science, 2018-05-09)
      The analysis of codon usage bias has been widely used to characterize different communities of microorganisms. In this context, the aim of this work was to study the codon usage bias in a natural consortium of five acidophilic ...
    • Inverse M-matrix, a new characterization 
      Dellacherie, Claude; Martínez Aguilera, Servet; San Martín Aristegui, Jaime (Elsevier, 2020)
      In this article we present a new characterization of inverse M-matrices, inverse row diagonally dominant M-matrices and inverse row and column diagonally dominant M-matrices, based on the positivity of certain inner products.
    • On polymorphism for discrete evolutionary dynamics driven either by selection or segregation distortion 
      Huillet, Thierry; Martínez Aguilera, Servet; Möhle, Martin (Springer, 2018-05)
      We revisit some problems arising in the context of multiallelic discrete-time and deterministic evolutionary dynamics driven first by fitness differences and then by segregation distortion. In the model with fitness, we ...
    • Potentials of random walks on trees 
      Dellacherie, Claude; Martínez Aguilera, Servet; San Martín Aristegui, Jaime (Elsevier, 2016)
      In this article we characterize inverse M-matrices and potentials whose inverses are supported on trees. In the symmetric case we show they are a Hadamard product of tree ultrametric matrices, generalizing a result by ...
    • Quasi-stationary distributions and resilience: What to get from a sample 
      Chazottes, Jean-René; Collet, Pierre; Martínez Aguilera, Servet; Méléard, Sylvie (Ecole Polytechnique, 2020)
      We study a class of multi-species birth-and-death processes going almost surely to extinction and admitting a unique quasi-stationary distribution (qsd for short). When rescaled by K and in the limit K ! +1, the realizations ...
    • Truncation in duality and intertwining kernels 
      Huillet, Thierry; Martínez Aguilera, Servet (Polymat, 2020)
      We study properties of truncations in the dual and intertwining process in the monotone case. The main properties are stated for the time-reversed process and the time of absorption of the truncated intertwining process.
