La comprensión y esta enfermedad han beneficiado a fitopatología, además, propiciado avances importantes otras ciencias como biotecnología microbiología. Hoy día, creciente resistencia frente los antibióticos utilizados para su control alerta sobre uso indebido est...

Computer Go presents a challenging problem for machine learning agents. With the number of possible board states estimated to be larger than the number of hydrogen atoms in the universe, learning effective policies or board evaluation functions is extremely difficult. In this paper we describe Cortigo, a system that efficiently and autonomously learns useful generalizations for large state-spac...

Nimisia deusta, based on Parmelia enteromorpha var. deusta, is shown to be the correct name for the species currently known as N. fuegiae. Original material collected by J. D. Hooker in 1842, and collections made by Henry Imshaug between 1968 and 1971, have shown that the species is more widely distributed than previously reported, being known throughout the southern tip of South America (Argen...
