Analysis of parabolic problems on partitioned domains with nonlinear conditions at the interface. Application to mass transfer through semi-permeable membranes.
No full textIn this work we address a problem governed by linear parabolic partial differential equations set in two adjoining domains, coupled by nonlinear interface conditions of Neumann type. In particular, we address the existence and uniqueness of strong solutions by applying the strong maximum principle, the Schauder fixed point theorem and the fundamental solutions of linear parabolic partial differential equations. In the first part of this work, we consider the properties of a linear parabolic partial differential equation set on a single domain with a nonlinear boundary condition. After having addressed the well-posedness and some comparison results for the problem on one domain, in the second part of this work we address the case of coupled problems on adjoining domains. In both cases, we complete the understanding of the behavior of the solution of the problems at hand by means of numerical simulations. The theoretical results obtained here are applied to study the behavior of a biological model for the transfer of chemicals through thin biological membranes. This model represents the dynamics of the concentration u of a chemical solution separated from the exterior by a semi-permeable membrane. The analysis of the two-domain problem that we carry out could also be used to investigate the convergence property of iterative substructuring methods applied to the approximation of multidomain problems with nonlinear coupling of Neumann typ
Revisión de las especies paleárticas del subgénero Onthophagus (sensu stricto) Latr. Los tipos de J. M. de La Fuente y M. de la P. Graélls en el Instituto Español de Entomología.
No full textThe type material of the Onthophagus species described by T. M. de la Fuente
and M. de la P. Graells is revised. The synonymy of O. distinctus la Fuente,
1910, whith O. latigena d'Orbigny, 1898, is confirmed. As the original material
of O. stylocerus Graélls is missing, the neotype of this species is designated.Peer reviewe

Type material examined ( 1 male, 2 females ). Paratypes. 1 male, 1 female: “ México, Parque Nacional J. M. Morelos, Morelia, Michoacán, 25/VII/64, P. Reyes C. col., en hongos” (GHC); 1 female: “ México, Valle de Bravo, Edo. de México, 25/VI/67, col. G. y V. Halffter, cebo excremento humano” (VMC). Non-type material examined. 1 female: “ México, Michoacán, Tejamaniles, 17/VIII/90. A. Morales, col.” (CEMT). Remarks. Length: 9.1 ± 0.1 mm. The following set of characters help us to support the new status of O. canescens (Table 1): pronotal pubescence medially absent (densely covering the entire surface in O fuscus); short elytral pubescence (long elytral pubescence in O. fuscus); major male frontal carina completely impressed (not impressed laterally in O. fuscus); major male pronotal prominence obtusely trapezoidal (obtusely triangular in O. fuscus); female frontal carina complete, rounded (not impressed laterally, trapezoidal in O. fuscus); apical-superior area of the parameres trapezoidal (obtuse in O. fuscus); apex of the inferior right lobe concave (claw shaped in O. fuscus). Onthophagus canescens occurs between 1700–2100 m in La Sierra de Mil Cumbres, central-western Trans-Mexican Volcanic Belt (Fig. 17).Published as part of Joaqui, Tatiana, Moctezuma, Victor, Sánchez-Huerta, José Luis & Escobar, Federico, 2019, The Onthophagus fuscus (Coleoptera: Scarabaeidae) species complex: an update and the description of a new species, pp. 151-186 in Zootaxa 4555 (2) on page 160, DOI: 10.11646/zootaxa.4555.2.1, http://zenodo.org/record/262421
Supporting visual quality assessment with machine learning
No full textObjective metrics for visual quality assessment often base their reliability on the explicit modeling of the highly non-linear behavior of human perception; as a result, they may be complex and computationally expensive. Conversely, machine learning (ML) paradigms allow to tackle the quality assessment task from a different perspective, as the eventual goal is to mimic quality perception instead of designing an explicit model the human visual system. Several studies already proved the ability of ML-based approaches to address visual quality assessment; nevertheless, these paradigms are highly prone to overfitting, and their overall reliability may be questionable. In fact, a prerequisite for successfully using ML in modeling perceptual mechanisms is a profound understanding of the advantages and limitations that characterize learning machines. This paper illustrates and exemplifies the good practices to be followed.Intelligent SystemsElectrical Engineering, Mathematics and Computer Scienc
