American Journal of Biological Anthropology, Volume 190, Issue 3, July 2026.ABSTRACT Stature estimation of skeletal remains is mostly dependent on the lengths of long bones, but these are often unavailable in fragmented or commingled assemblages. To overcome this obstacle, we present an extension of the unisex stature estimation models for high‐altitude Andean populations presented by Anzellini and Toyne (2020) using femoral ...

Brain and Behavior, Volume 16, Issue 6, June 2026.ABSTRACT Purpose This study examined the relationship between body composition and cardiac autonomic nervous system activity in educators. The objective was to explore the associations between body fat mass (BFM) and fat‐free mass (FFM) with different heart rate variability (HRV) indices in a sample of educators and to assess whether FFM moderates the ...

Algunas cuestiones abiertas relativas al crecimiento biológico
Arbor: Ciencia, Pensamiento y Cultura, 2010 En este trabajo revisamos brevemente las propiedades de las superficies que crecen de forma radial y su conexión con el crecimiento biológico. Nos vamos a concentrar en modelos simplificados que resultan de la abstracción de sólo considerar el ...

Effects of parachute science on local research capacity 降落伞科学对当地研究能力的影响
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Strengthening research capacity is essential to address the global biodiversity crisis. Yet, parachute science often undermines this goal, and its prevalence, costs, and benefits are unclear. We analyzed 13,502 publications on primate research that we extracted from Scopus (1960–2022) to evaluate the effects of parachute science on local ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Acotación del error de modelos de redes neuronales aplicados al pronóstico de series de tiempo
Revista UIS Ingenierías, 2011 Las redes neuronales artificiales son una importante técnica en el pronóstico de series de tiempo no lineales. Sin embargo,el entrenamiento de las redes neuronales es una tarea difícil, a causa de la presencia de muchos puntos óptimos localesy a la ...
