Longitudinal maternal hemodynamics in high‐risk pregnancies with different subtypes of pre‐eclampsia

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 5, Page 623-634, May 2026.
ABSTRACT Objective To evaluate maternal cardiac adaptation during pregnancy by comparing longitudinal hemodynamic profiles between women identified as high risk for preterm pre‐eclampsia (PE) who subsequently developed preterm PE, term PE or remained unaffected, as well as low‐risk women.

Modelación de respuestas ordinales longitudinales mediante Modelos Lineales Generalizados Mixtos [PDF]

, 2016
Los Modelos Lineales Generalizados Mixtos (MLGM) son una extensión del modelo lineal generalizado (MLG) adicionando los efectos aleatorios. En particular en estudios longitudinales un camino de modelación es considerar al individuo como efecto aleatorio.

Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

Functional Ecology, Volume 40, Issue 5, Page 1270-1285, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...

Unraveling the Phenology of the Liana Marcgravia longifolia: Temporal Patterns and Climatic Cues

Biotropica, Volume 58, Issue 2, March 2026.
We monitored the reproductive phenology of the Amazonian liana Marcgravia longifolia J. F. Macbr (Marcgraviaceae) for 84 consecutive months in the Peruvian Amazon to quantify the timing, synchrony, and seasonality of flowering and ripe fruiting. Flower presence peaked in August with intermediate synchrony, while ripe fruit presence peaked in November ...

Modelos lineales mixtos para la programación de la producción con una sola etapa: estado del arte

Dirección y Organización, 2022
This paper presents a review of the state-of-the-art literature and a subsequent taxonomy of mixed linear programming models (MILP) developed for production planning. Specifically, single-stage models are analysed due to their relevance to various scenarios.

Successional and native forests predict the occurrence and infection status of Chagas disease vectors in Panama

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Findings here show that successional forest predicts greater kissing bug infestation risk in palm trees, whereas native forest predicts lower kissing bug occurrence but greater infection with T. cruzi. These insights can guide land use planning towards vegetation management practices that help minimize T. cruzi transmission risks for rural communities.

Sobre la construcción del mejor predictor lineal insesgado (BLUP) y restricciones asociadas

Revista Colombiana de Estadística, 2007
A través del modelo lineal clásico de Gauss-Markov, se caracteriza el modelo de efectos mixtos, se aplica la técnica de multiplicadores de Lagrange para obtener los mejores predictores lineales (BLUP) y se ilustran los resultados de Searle (1997), donde ...
