Multilevel Monte Carlo for continuous time Markov chains, with applications in biochemical kinetics [PDF]

, 2012
We show how to extend a recently proposed multi-level Monte Carlo approach to the continuous time Markov chain setting, thereby greatly lowering the computational complexity needed to compute expected values of functions of the state of the system to a ...

Comparing Mingoti and Glória's and Niverthi and Dey's multivariate capability indexes Comparando os coeficientes de capacidade multivariados de Mingoti e Glória e Niverthi e Dey

Production, 2008
In this paper a comparison between Mingoti and Glória's (2003) and Niverthi and Dey's (2000) multivariate capability indexes is presented. Monte Carlo simulation is used for the comparison and some confidence intervals were generated for the true ...

An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

Detecting extirpation: A localized approach to a global problem

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1160-1174, July 2026.
The global biodiversity crisis stems from a cascading series of extirpations driving species toward extinction. Addressing this crisis requires methods for early detection of extinction at local scales, where communities can mobilize conservation efforts.

First‐trimester prediction and prevention of preterm pre‐eclampsia in women with chronic hypertension

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 5, Page 613-622, May 2026.
ABSTRACT Objectives To evaluate the effect of aspirin on gestational age at delivery due to preterm pre‐eclampsia (PE) in women with chronic hypertension (CH), to assess the predictive performance of the Fetal Medicine Foundation (FMF) first‐trimester competing‐risks model for preterm PE in this high‐risk group and to evaluate how parity, previous PE ...

Validação dosímetrica de trabéculas ósseas sintéticas geradas por método Monte Carlo paramétrico

Brazilian Journal of Radiation Sciences, 2018
Um dos maiores desafios da dosimetria numérica é estimar a dose de radiação ionizante absorvida pelos tecidos moles que se localizam nas trabéculas ósseas. Em função da dificuldade na obtenção de imagens micro-CT de amostras de ossos reais (OR), surgiu a

CMiNet: An R package and user‐friendly Shiny App for constructing consensus microbiome networks

Methods in Ecology and Evolution, Volume 17, Issue 1, Page 52-66, January 2026.
Abstract Microbial networks offer critical insights into community structure, ecological interactions and host–microbe dynamics. However, constructing reliable microbiome networks remains challenging due to variability among existing inference methods, limited overlap between inferred networks and the absence of a gold standard (a universally accepted ...
