Using an incomplete block design to allocate lines to environments improves sparse genome-based prediction in plant breeding

Osval Antonio Montesinos-Lopez ABELARDO MONTESINOS LOPEZ RICARDO ACOSTA DIAZ Rajeev Varshney Jose Crossa ALISON BENTLEY (2022, [Artículo])

Genomic selection (GS) is a predictive methodology that trains statistical machine-learning models with a reference population that is used to perform genome-enabled predictions of new lines. In plant breeding, it has the potential to increase the speed and reduce the cost of selection. However, to optimize resources, sparse testing methods have been proposed. A common approach is to guarantee a proportion of nonoverlapping and overlapping lines allocated randomly in locations, that is, lines appearing in some locations but not in all. In this study we propose using incomplete block designs (IBD), principally, for the allocation of lines to locations in such a way that not all lines are observed in all locations. We compare this allocation with a random allocation of lines to locations guaranteeing that the lines are allocated to

the same number of locations as under the IBD design. We implemented this benchmarking on several crop data sets under the Bayesian genomic best linear unbiased predictor (GBLUP) model, finding that allocation under the principle of IBD outperformed random allocation by between 1.4% and 26.5% across locations, traits, and data sets in terms of mean square error. Although a wide range of performance improvements were observed, our results provide evidence that using IBD for the allocation of lines to locations can help improve predictive performance compared with random allocation. This has the potential to be applied to large-scale plant breeding programs.

Las patologías de los recubrimientos en muros y su repercusión en la salud respiratoria de los usuarios

251 páginas. Doctorado en Diseño Bioclimático.

El nivel de calidad del aire interior (CAI) tiene incidencia directa en la salud humana, por eso, es objeto de estudio del diseño bioclimático, toda vez que éste promueve el aprovechamiento de los factores ambientales para la creación y acondicionamiento de espacios en los que los usuarios experimenten confort y bienestar. Además, de impulsar la construcción con sentido común, en donde prevalezca el uso racional de los recursos y una baja dependencia energética. En la presente tesis se pudieron identificar las propiedades de los materiales más comunes que conforman los recubrimientos de muros (cal, cemento, mortero de cemento y yeso) para reconocer los que mejor se adaptan al clima en la Cd. de México, mismos que según se pudo constatar, contribuyen en el control de algunos factores de riesgo (físico: humedad, químico: tóxicos y biológico: microbios) relacionados con una baja calidad del aire al interior de las viviendas. Tal función mitiga o reduce la aparición de algunos de los padecimientos respiratorios más frecuentes en los usuarios como: alergias, asma, rinitis, gripe y sinusitis. Los análisis a los que fueron sometidos los recubrimientos de cuatro materiales ligantes, permitieron evaluar su desempeño ante factores ambientales semi-controlados (temperatura, humedad relativa y concentración de dióxido de carbono) inherentes al funcionamiento del propio espacio interior y al lugar de emplazamiento del mismo. Obviamente, todos los recubrimientos reaccionaron de forma distinta y acorde con las propiedades físicas y químicas de los materiales presentes en cada uno de ellos. Siendo las variaciones más representativas y satisfactorias, las relacionadas con la permeabilidad y el efecto biocida de los recubrimientos hechos con mezcla de cal. Las patologías que mostraron algunos recubrimientos a lo largo del periodo de monitoreo, debido a la insuficiente gestión de la humedad, al alto desarrollo microbiano y a la naturaleza química del material ligante, fueron criptoeflorescencias, moho, bacterias y desprendimiento/diseminación de partículas; mismas que se consideraron definitorias para establecer que al igual que los seres vivos, los materiales de construcción necesitan rangos higrotérmicos específicos, que permitan su óptimo estado de operación. En apego a lo anteriormente citado, es que se considera conveniente concientizar a la población en temas tan importantes para el bienestar social, como la selección de materiales y -consecuente- conservación de los recubrimientos de muros, no sólo para disminuir los costos de ejecución y mantenimiento, sino para aprovechar sus propiedades, ya que tienen una incidencia directa en lo relacionado con el control de las condiciones ambientales básicas, la regulación de la calidad del aire interior y por ende, en la salud de los usuarios. Dicha labor puede iniciar en la etapa formativa de los profesionales de la construcción, con la intención de normalizar el estudio o correcta selección de los sistemas constructivos en función del clima, pero también identificando la función de cada espacio; para garantizar así, que las propuestas de diseño responderán -satisfactoriamente- a los requerimientos de regulación de la humedad, mediante su absorción, transpiración y/o evaporación.

The level of indoor air quality (IAQ) has a direct incidence on the human health, therefore, is the object of study of bioclimatic design, since it promotes the harnessing environmental factors for the creation and conditioning of spaces in which users experience comfort and well-being. In addition, to encourage construction with common sense, where the rational use of resources and low energy dependence prevail. In this thesis it has been identified the properties of the materials that make up the most common wall coverings (hydrated lime, cement, cement mortar and gypsum) for recognizing those that best adapt to the weather in Mexico City, as it could be verified, they contribute to the control of some risk factors (physical:moisture, chemical:toxics and biological:microbes) related with a low indoor air quality at dwellings. This function mitigates or reduces the appearance of some of the most frequent respiratory ailments in users such as: allergies, asthma, rhinitis, flu and sinusitis. The analyses to which the coatings of four binding materials were subjected, allowed to evaluate their performance in the face of semi-controlled environmental factors (temperature, relative humidity, and carbon dioxide concentration) inherent to the operation of the interior space itself and the place of its location. Obviously, all the coatings reacted differently and according with the physical and chemical properties of the materials in each of them. Being the most representative and satisfactory variations, those related to the permeability and biocidal effect of coatings made with hydrated lime mixture. The pathologies that some coatings showed throughout the monitoring period, due to insufficient moisture management, the high microbial development, and the chemical nature of the binding material, were cryptoefflorescences, mold, bacteria and particle shedding/dissemination; they were defining to establish that in similar way to living beings, building materials need specific hygrothermal ranges, to let them works in an optimal state. According with the above, it is considered convenient to raise awareness among the population on issues as important for social welfare, such as the selection of materials and -consequently- conservation of wall coverings, not only to reduce the costs of execution and maintenance, but to take advantage of their properties, since they have a direct incidence in all related with the control of basic environmental conditions, the regulation of indoor air quality and therefore, in users’ health. This work can begin in the formative stage of construction professionals, with the intention of standardizing the study or correct selection of construction systems depending on the weather, but also identifying the function of each space; to guarantee that the design proposals will respond -satisfactorily- to the requirements of humidity regulation, through its absorption, transpiration and/or evaporation.
