Ecuaciones de optimalidad para el criterio del costo promedio sensible al riesgo en procesos de decisión markovianos sobre un espacio finito
Publicado 2013“…Next, in Chapter 2 a fundamental theorem by Howard and Matheson (1972), as well as a recent extension on the characterization of the optimal average cost in terms of a single optimality equation are analyzed; such results require that, under the action of any stationary policy, every state can be visited with positive probability regardless of the initial sate, and the arguments used in this work emphasize the central role of that communication property. …”

Alimentary Biostoichiometry Toward a Bigger Productivity and a Low Environmental Impact.
Publicado 2019“…The "Alimentary Biostoichiometry", was born in our science group like to necessity ofinterpretation of countless and complex interrelations and results it causes - effect obtainedin all our chore in nutrition where the sequence interpretations have been conjugated; basicand applied investigation; disciplines like biotechnology, genetics, molecular biology,evolution, ethology, physiology, biochemistry, immunochemistry, embryology,bioenergétic, sciences of the nutrition; cumulative experience among others.The feeding and nutrition in aquaculture is based fundamentally on charts and preseteddates which don't consider the relationships phylo and ontogenetics, ontogeny of mobilityand molecular relationships of amino acids integrally for example free amino acids, freeand combined amino acids , and total aa. of proteins, enzymes, peptides etc., ramified aa.,muscular tissue precursors, aa precursors of collagen, aa. precursors of immunity etc., typesof fatty acids, besides the physiologic state, homeostasis, enzymatic ontogeny, transferases,ATP-aces, psicrofílic enzymes like CST and AST, habits of natural feeding, umami,frequency, age etc.The "Alimentary Biostoichiometry", it conjugates the disciplines approaching the problemof a more holistic point of view where the essential thing is marked for "modulations" orchanges that are allowed to see as "Specie-Specific-Stadium" (SSS).Having identified some factors of biomasic grow v/s for example the development of thedigestive capacity and on the other hand the natural morbimortality in larvae of Salmosalar, have been formulated and developed practical diets according to obtained results,comparing finally this diets with commercial allowances of high conversion grade.…”
