Sviluppo e validazione di metodologie di miglioramento genetico dell'orzo basate sulla predizione genomica per sostenere l'innovazione varietale e l'agricoltura del futuro.
… di individui o collezioni di accessioni (training population) sono utilizzati per costruire il modello predittivo, utilizzando sia dati fenotipici sia dati genotipici. Successivamente il modello predittivo è applicato ad individui dei quali si conoscono solamente i dati genotipici …

Genomewide Selection in Apple: Prediction and Postdiction in the University of Minnesota Apple Breeding Program
… ability when full-sibs are included in the training data. This research finds that in general, a simple linear model is the most efficient choice for genomewide selection in apple unless major effect QTL are known, in which case including them as fixed effects may improve predictive …

Optimizing GWS and GWAS in crop breeding
… addition, it also provided an assessment of the population structure for the joint dataset with the two countries as well as genetic parameters estimations based on single nucleotide polymorphisms (SNPs) and in a haplotype approach. Comparisons on GEBVs’ estimation were made considering the …

Win, loose or draw? : do employers benefit from hiring workers through Boston-based job training programs ?/
… "change welfare as we know it," traditional job training programs in Massachusetts have inadvertently come under siege. State law-makers are eschewing job training in favor of work-first policies -- mandating most public assistance recipients work or volunteer a minimum of twenty hours per week …

Predicting surgical inpatients' discharges at Massachusetts General Hospital
… key piece of information for bed managers. Given training population of 15,553 surgical inpatients admitted to MGH between May 2016 and August 2017, and test population (out-of-sample) of 1,151 surgical inpatients hospitalized during September 2017, the model achieved remarkable performance with …

Statistical modeling strategies for estimation of the arterial input function in dynamic positron emission tomography data analysis
… To improve on this first model, we developed a population-based projection model that exploits historical data to estimate individual AIFs. We represent the history of a tracer atom at a sampling site by its travel time, modeled as a sum of the time for the atom to initially progress from the …

Genomic Selection, Quantitative Trait Loci and Genome-Wide Association Mapping for Spring Bread Wheat (Triticum aestivum L.) Improvement
… spring bread wheat, ii) determine the effects of training population (TP) size, marker density, and population structure on genomic prediction accuracy, iii) examine GS prediction accuracy when modelling genotype-by-environment interaction (G × E) using different approaches, iv) detect …

Genomic selection and quantitative trait loci mapping for Fusarium head blight resistance in wheat (Triticum aestivum L.)
… (p = 500, 1500, 3000, and 4500 SNPs); and iv) training population size (nTP = 96, 144, 192, and 218). No discernable differences in prediction accuracy were observed among imputation methods. For five of six traits, RR-BLUP outperformed other statistical models (LASSO and elastic-net), and a …

Genomic improvement of nitrogen utilization efficiency in maize
… that were not captured by the IBM mapping population used for QTL analysis. A genomic prediction approach was used to capture small genetic effects across the genome. Within year prediction accuracies for genomic prediction of grain nitrogen were 0.5 when the training population is 30% of …

Study of genetic by environmental interactions at transcriptomic and genomic levels
… fashion, genetic variability in the human population is responsible for the difference in drug efficiency on the treatment of several diseases. The development of high-throughput genomic and transcriptomics technologies has been providing rapid access to DNA and RNA information in humans …

Valor económico y social de los jóvenes con potencial en Bogotá
Los jóvenes con potencial son el conjunto de jóvenes entre los 14 y 28 que ni estudian ni trabaja (más conocidos como Ninis), así como aquellos que se encuentran trabajando en la informalidad. En Bogotá, los jóvenes con potencial representan el 35,8% de los jóvenes, siendo en su mayoría mujeres que …
