Solution of Few-Body Coulomb Problems with Latent Matrices on Multicore Processors

We re-formulate a classical numerical method for the solution of systems of linear equations to tackle problems with latent data, that is, linear systems of dimension that is a priori unknown. This type of systems appears in the solution of few-body Coulomb problems for Atomic Simulation Physics, in the form of multidimensional partial differential equations (PDEs) that require the numerical solution of a sequence of recurrent dense linear systems of growing scale. The large dimension of these systems, with up to several hundred thousands of unknowns, is tackled in our approach via a task-parallel implementation of the solver, using the OmpSs framework.Fil: Biedma, Luis Ariel.

Metabolic impairments caused by a “chemical cocktail” of DDE and selenium in mice using direct infusion triple quadrupole time of flight and gas chromatography mass spectrometry

Among organic contaminants, pesticides are one of the most important groups of chemicals due to their persistent character and toxicity. However, the biological systems are exposed to a complex environment in which the contaminants can interact in a synergistic/antagonistic fashion, and for this reason, the study of “chemical cocktails” is of great interest to fully understand the final biological effect. In this way, selenium is known for its antagonistic action against several toxicants. In this paper, metabolic impairments caused by the joint exposure of p,p′-dichloro diphenyl trichloroethane (DDE) and selenium (Se) have been issued for the first time. A metabolomic workflow was applied to mice fed DDE and DDE with Se diet, on the basis of the complementary use of two organic mass spectrometric techniques, combining direct infusion mass spectrometry (DI-ESI-QqQ-TOF MS) and gas chromatography–mass spectrometry (GC–MS). The results show a good classification between the studied groups caused by about 70 altered metabolites in the liver, kidney, or brain, including the pathways of energy metabolism, degradation of phospholipidic membrane, β-oxidation, and oxidative stress, which confirm the potential of combined metabolomic platforms in environmental studies.This work has been supported by projects CTM2015-67902-C2-1-P and PG2018-096608 B-C21 from the Spanish Ministry of Economy and Competitiveness and P12-FQM-0442 and B10-1657 from the Regional Ministry of Economy, Innovation, Science and Employment (Andalusian Government, Spain).

Optimización del transporte de caudales en el marco de la vinculación entre FAMAF-UNC y Tarjeta Naranja SA

Aprovechando el vínculo institucional establecido entre Naranja y FAMAF-UNC, formalizado desde fines de 2018, desde la empresa se planteó la necesidad de optimizar el envío de camiones de la empresa. transportadora de caudales para retirar las recuadaciones de efectivo acumuladas en las más de 180 sucursales de la empresa distribuidas en todo el territorio del país. En primera instancia, el requerimiento fue de minimizar el costo logístico y luego de minimizar el costo total incorporando también el costo financiero de los montos inmovilizados en las sucursales. Se proveyó una solución empleando programación lineal y una implementación en Python basada en un solver open source. Se lograron tiempos de procesamiento de minutos para reemplazar una tarea, manual que requería decenas de horas-persona de trabajo mensuales.Sociedad Argentina de Informática e Investigación Operativ

MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal

Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.

Algunos aspectos sobre el mundo del vino en la Tierra Llana de Huelva en la primera mitad del siglo XVIII

Bollullos del Condado se configura como un área de cultivo y centro de producción vinícola en la Tierra Llana de Huelva durante la primera mitad del XVIII. En el artículo se analiza tanto sus bodegas como la tecnología empleada en las mismas, así como la presencia de intermediarios mercantiles procedentes de Moguer que abarca y domina todo el proceso de exportación y comercialización del vinoBollullos del Condado is configured as a vineyard area for wine production in the Tierra Llana (flat land) of Huelva during the first half of the 18th century. The article analyses the wineries and the technology used in them, as well as the presence of commercial intermediaries from Moguer, the town that controls the whole process of wine export and commercializatio

Las “catedrales bollulleras del vino”. Un nucleo industrial bodeguero en el último tercio del XVIII

En Bollullos Par del Condado (Huelva) un mayor dinamismo del negocio vitivinícola, en los últimos decenios del siglo XVIII, permitirán la consolidación de un núcleo industrial- bodeguero en el entorno del arroyo de la Cerrada. Partiendo de esta premisa se analiza la gestación y puesta en funcionamiento en este periodo de tres bodegas que son vestigios de un modelo de arquitectura popular andaluza, hoy prácticamente desaparecido. Por su belleza e importancia las denominaremos “Catedrales bollulleras del vino”In Bollullos Par del Condado (Huelva) a greater dynamism of wine business in the last decades of the 18th century, will allow the consolidation of a winery-industrial centre in the surroundings of Cerrada stream. Based on this premise, we analyse the gestation and commissioning in this period of three new winerieswhich are vestiges of Andalusian popular architecture, today practically disappeared. For their beauty and importance we will call them “Wine bollulleras cathedrals
