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 ...

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Simultaneous Generation of Topographic Models and Manning Roughness Coefficient Maps From Tri‐Stereoscopic Satellite Images: Application to the Huarmey River, Peru

The Photogrammetric Record, Volume 41, Issue 195, July‐September 2026.
Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...

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 ...

Carbon Credits Through Wood Use: Revisiting the Maximum Potential and Sensitivity to Key Assumptions

GCB Bioenergy, Volume 17, Issue 2, February 2025.
We investigated how large and uncertain avoided fossil‐based emissions and net sequestration of carbon into the technosphere (TCCs = technosphere carbon credits) of wood use per carbon harvested are. The mean value of TCCs of wood use were between 0.2 and 0.5 tC/tC with an uncertainty range from 0.1 to 0.8 tC/tC, depending on the scenario.
