In nature, some species mate according to their phenotype similarity. The Assortative Mating Genetic Algorithm (AMGA) mimics some mechanisms of reproduction in natural environments. The main difference between AMGA and the Standard GA (SGA) is the selection of the parents in the crossover operators. We develop a similarity measure for the Vector(More)

Ectomycorrhizal symbiosis is essential for the life and health of trees in temperate and boreal forests where it plays a major role in nutrient cycling and in functioning of the forest ecosystem. Trees with ectomycorrhizal root tips are more tolerant to environmental stresses, such as drought, and biotic stresses such as root pathogens. Detailed information(More)
Cork oak (Quercus suber) is one of the rare trees with the ability to produce cork, a material widely used to make wine bottle stoppers, flooring and insulation materials, among many other uses. The molecular mechanisms of cork formation are still poorly understood, in great part due to the difficulty in studying a species with a long life-cycle and for(More)
– This paper presents a 14-bit 1.5 MSample/s two-stage algorithmic ADC with a power-and-area efficiency better than 0.5 pJmm 2 per conversion. This competes with the most efficient architectures available today namely, ΣΔ and self-calibrated pipeline. The 2 stages of the ADC are based on a new 1.5-bit mismatch-insensitive MDAC and simulations demonstrate(More)
