Estimación de la capacidad potencial de secuestro y emisión de CO2 de los suelos agrícolas de la Comunidad Valenciana por Visconti, Fernando, De-Paz, José M.

“…Esta estimación se ha realizado en base al promedio y variabilidad espacial del contenido de materia orgánica del suelo agrícola dentro de zonas agroecológicas homogéneas en clima, tipo de suelo y uso del suelo y usando técnicas de SIG, geoestadística y álgebra de mapas. Las capacidades de secuestro y emisión resultan ser así de 24.0 y 22.0 Mt de carbono, respectivamente. …”

GAMS code for estimating a Social Accounting Matrix (SAM) using cross entropy methods (CE) por Robinson, Sherman, El-Said, Moataz

“…This paper documents the computer code implementing the CE-SAM estimation technique in GAMS (General Algebraic Modeling System). It defines the estimation problem in a deterministic setting; extends the approach to include a stochastic treatment of errors in control totals; summarizes the equations describing CE technique for estimating a consistent SAM starting from an inconsistent data set estimated with error; and provides the GAMS code.…”

The effect of epistasis between linked genes on quantitative trait locus analysis por Asins, María J., Carbonell, Emilio A.

“…In this case, the presence of main-effect QTLs is due to the deviation of the heterozygote from the homozygotes at each linked interacting QTL and is algebraically explained by the joint effect of the linkage and the additive-by-additive interaction, resulting in a heterosis at a single genomic region in the absence of simulated dominant genetic effects. …”
