Nonpositively curved metric in the positive cone of a finite von Neumann algebra
(Oxford University Press, 2006-08)
In this paper we study the metric geometry of the space Σ of positive invertible elements of a von Neumann algebra. A with a finite, normal and faithful tracial state T. The trace induces an incomplete Riemannian metric ...
Retinal photoreceptors of two subterranean tuco-tuco species (Rodentia, Ctenomys): Morphology, topography, and spectral sensitivity
(Wiley-liss, Div John Wiley & Sons Inc, 2010-10)
Traditionally, vision was thought to be useless for animals living in dark underground habitats, but recent studies in a range of subterranean rodent species have shown a large diversity of eye features, from small ...

A role for the endogenous opioid β-endorphin in energy homeostasis
(Endocrine Society, 2003-05)
Proopiomelanocortin (POMC) neurons in the hypothalamus are direct targets of the adipostatic hormone leptin and contribute to energy homeostasis by integrating peripheral and central information. The melanocortin and ...
Subsurface architecture of Las Bombas volcano circular structure (Southern Mendoza, Argentina) from geophysical studies
(Pergamon-Elsevier Science Ltd, 2017-08)
The Plio-Pleistocene Llancanelo volcanic field is located in the south-eastern region of the province of Mendoza, Argentina. This wide back-arc lava plateau, with hundreds of monogenetic pyroclastic cones, covers a large ...
A Multiethnic Study of Pre-Diabetes and Diabetes in LMIC
(Elsevier, 2016-03)
Background Diabetes mellitus is one of the leading causes of death and disability worldwide. Approximately three-quarters of people with diabetes live in low- and middle-income countries, and these countries are projected ...
Reconstructing the early evolution of the cupressaceae: A whole-plant description of a new austrohamia species from the cañadón asfalto formation (early Jurassic), Argentina
(University of Chicago Press, 2019-10)
Premise of research. A new Early Jurassic species of Cupressaceae is reconstructed from the Cañadón Asfalto Formation in Argentina, based on impressions of foliage and attached and dispersed seed and pollen cones. Methodology. ...
Growth architecture and silhouette of Jurassic conifers from La Matilde Formation, Patagonia, Argentina
(Elsevier Science, 2011-03)
Simple morphological traits are used to describe the architecture of a tree: the growth and branching process, the morphological differentiation of the axes and the position of reproductive structures. The main purpose of ...
A Sequential Optimality Condition Related to the Quasi-normality Constraint Qualification and Its Algorithmic Consequences
(Society for Industrial and Applied Mathematics, 2019-03)
In the present paper, we prove that the augmented Lagrangian method converges to KKT pointsunder the quasinormality constraint qualification, which is associated with the external penalty theory. An interesting consequence ...
Normal percentile curves for left atrial size in healthy children and adolescents
(Wiley, 2019-02)
Background: Despite the clinical utility of echocardiography to measure left atrial (LA) structure and function, there are scarcities of data about the percentiles of LA diameter (LAD), LA volume (LAVOL), and LA volume ...
