Classical approximation of a linearized three waves kinetic equation
Escobedo Martínez, Miguel
(Elsevier, 2022-04-15)
The purpose of this work is to solve the Cauchy problem for the classical approximation of an isotropic linearized three waves kinetic equation that appears in the kinetic theory of a condensed gas of bosons near the ... -
Clinical prediction rules for adverse evolution in patients with COVID-19 by the Omicron variant
(Elsevier, 2023-05)Objective We identify factors related to SARS-CoV-2 infection linked to hospitalization, ICU admission, and mortality and develop clinical prediction rules. Methods Retrospective cohort study of 380,081 patients ... -
Cohomologically Kähler manifolds with no Kähler metrics
Fernández Rodríguez, María Luisa; ; Santisteban Elorriaga, José Antonio (Hindawi Publishing Corporation, 2003)
We show some examples of compact symplectic solvmanifolds, of dimension greater than four, which are cohomologically Kähler and do not admit Kähler metric since their fundamental groups cannot be the fundamental group ... -
Cohomology of p-groups of nilpotency class smaller than p
(De Gruyter, 2018-01-17)Let p be a prime number, let d be an integer and let G be a d-generated finite p-group of nilpotency class smaller than p. Then the number of possible isomorphism types for the mod p cohomology algebra H^∗(G;F_p) is bounded ... -
Computational and Experimental Evaluation of the Immune Response of Neoantigens for Personalized Vaccine Design
Malaina Celada, Iker; ; Martínez Fernández, Luis ; Salvador Martínez, Aiala ; ; Asumendi Mallea, Aintzane ; ; ; ; ; Pérez Pinilla, Martín Blas ; ; ; Igartua Olaechea, Manuela ; Alonso Alegre, Santos ; Hernández Martín, Rosa María ; Boyano López, María Dolores (MDPI, 2023-05-19)
In the last few years, the importance of neoantigens in the development of personalized antitumor vaccines has increased remarkably. In order to study whether bioinformatic tools are effective in detecting neoantigens that ... -
Conciseness in compact R-analytic groups
(Elsevier, 2023-06)We prove that every word is concise in the class of compact R- analytic groups. That is, for every word w and every compact R-analytic group G such that the set of word values w{G} is finite, the verbal subgroup w(G) ... -
Constant mean curvature hypersurfaces with constant δ-invariant
(Hindawi Publishing Corporation, 2003)We completely classify constant mean curvature hypersurfaces (CMC) with constant δ-invariant in the unit 4-sphere S4 and in the Euclidean 4-space E4. -
Convexity properties of discrete Schrödinger evolutions
Fernández Bertolin, Aingeru (Springer Nature, 2019-07-01)
In this paper, we give log-convexity properties for solutions to discrete Schrödinger equations with different discrete versions of Gaussian decay at two different times. For free evolutions, we use complex analysis arguments ... -
Diagnosis of the health status of mooring systems for floating offshore wind turbines using autoencoders
; Pardo Zubiaur, David; (Elsevier, 2023-11)
Floating offshore wind turbines (FOWTs) show promise in terms of energy production, availability, and sustainability, but remain unprofitable due to high maintenance costs. This work proposes a deep learning algorithm to ... -
Discrete Carleman estimates and three balls inequalities
Fernández Bertolin, Aingeru; Roncal Gómez, Luz; Rüland, Angkana; Stan, Diana (Springer, 2021-12)
[EN]We prove logarithmic convexity estimates and three balls inequalities for discrete magnetic Schrodinger operators. These quantitatively connect the discrete setting in which the unique continuation property fails and ... -
Dynamical versions of Hardy's uncertainty principle: A survey
Fernández Bertolin, Aingeru; Malinnikova, Eugenia (American Mathematical Society, 2021-06-03)
The Hardy uncertainty principle says that no function is better localized together with its Fourier transform than the Gaussian. The textbook proof of the result, as well as one of the original proofs by Hardy, refers to ... -
Eigenvalue curves for Generalized MIT bag models
; ; Vega González, Luis; Sanz Perela, Tomás (Springer, 2023-01)
We study spectral properties of Dirac operators on bounded domains ⊂ R3 with boundary conditions of electrostatic and Lorentz scalar type and which depend on a parameter τ ∈ R; the case τ = 0 corresponds to the MIT bag ... -
Enriched lower separation axioms and the principle of enriched continuous extension
(Elsevier, 2023-09-30)[EN] This paper presents a version of the lower separation axioms and the principle of enriched continuous extension for quantale-enriched topological spaces. As a remarkable result, among other things, we point out that ... -
Estimating Attraction Basin Sizes of Combinatorial Optimization Problems
; Hernando Rodríguez, Leticia; ; (Springer, 2018-07-20)
[EN]Given a particular instance of a combinatorial optimization problem, the knowledge about the attraction basin sizes can help to analyze the difficulty encountered by local search algorithms while solving it. As calculating ... -
Estimation of preterm labor immediacy by nonlinear methods
Malaina Celada, Iker; Martínez Fernández, Luis ; ; ; ; ; ; ; Pérez Pinilla, Martín Blas ; (Public Library Science, 2017-06-01)
Preterm delivery affects about one tenth of human births and is associated with an increased perinatal morbimortality as well as with remarkable costs. Even if there are a number of predictors and markers of preterm delivery, ... -
Evidence of conditioned behavior in amoebae
