Health indices of green turtle (Chelonia mydas) along the pacific coast of Baja California Sur, Mexico. II. Body condition index
(Chelonian Conservation and Biology, 2010)
Body condition index is used as a measure for an individual’s condition, usually with reference to its nutritional status and the energy reserves. Reproductive success, survival, and thus, population dynamics, depend on ...

Rewarded associative and instrumental conditioning after neonatal ventral hippocampus lesions in rats
(ELSEVIER SCIENCE BV, 2008)
Sprague Dawley rats were submitted to bilateral ventral hippocampus lesions 7 days after birth. This corresponds to the Lipska and Weinberger`s procedure for modeling schizophrenia. The aim of the present work was to test ...
Necessary conditions of optimality for state constrained infinite horizon differential inclusions
This article presents and discusses necessary conditions of optimality for infinite horizon dynamic optimization problems with inequality state constraints and set inclusion constraints at both endpoints of the trajectory. ...
Conditional alphas and realized betas
This paper proposes a two-step procedure to back out the conditional alpha of a given stock using high-frequency data. We rst estimate the realized factor loadings of the stocks, and then retrieve their conditional alphas ...
KT-invexity in optimal control problems
(Pergamon-Elsevier B.V. Ltd, 2009-11-15)
We extend the notion of KT-invexity from mathematical programming to the classical optimal control problem and show that this generalized invexity property is not only a sufficient condition of optimality for KT-processes ...
Necessary and sufficient condition for generalized passivity, passification and application to multivariable adaptive systems
Recently, a generalized passivity concept for linear multivariable systems was obtained which allows circumventing the restrictiveness of the usual passivity concept. The latter is associated with the classical SPR (Strictly ...
