A Sequential Monte Carlo Method for Bayesian Poisson Process Trees

Stat, Volume 15, Issue 4, December 2026.
ABSTRACT Statistical analysis of spatial point patterns often needs to deal with heterogeneous structures in intensity function estimation with possibly high‐dimensional covariate space. Likelihood based inference for spatial point process models needs to address the challenges in evaluating the multidimensional integral of random intensity function ...

Four Decades of Research at the MADE Site and Beyond: Advancing the Understanding and Modeling of Solute Transport in Heterogeneous Media

Reviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Spatial heterogeneity, manifested as strong variability in hydraulic conductivity (K) within geological formations, exerts a fundamental control on groundwater flow and solute transport. Because K can vary over multiple orders of magnitude in complex three‐dimensional patterns, predicting contaminant plume migration remains a long‐standing ...

Non‐Invasive Fibrosis Testing in Adults With Obesity and MASLD: A Systematic Review and Meta‐Analysis

Diabetes, Obesity and Metabolism, Volume 28, Issue 12, Page 11578-11590, December 2026.
ABSTRACT Aims Adults with obesity are at increased risk of metabolic dysfunction‐associated steatotic liver disease (MASLD)‐related fibrosis, but the diagnostic performance of non‐invasive tests (NITs) in this population remains uncertain. This meta‐analysis evaluated NITs for detecting significant (≥F2) and advanced (≥F3) fibrosis in adults with ...

Specification Tests for Jump‐Diffusion Models Based on the Characteristic Function

International Statistical Review, Volume 94, Issue 3, Page 738-768, December 2026.
Summary Goodness‐of‐fit tests are suggested for several popular jump‐diffusion processes. The suggested test statistics utilise the marginal characteristic function of the model and its L2‐type discrepancy from an empirical counterpart. Model parameters are estimated either by minimising the aforementioned L2‐type discrepancy or by maximum likelihood ...

On multilevel quadrature for elliptic stochastic partial differential equations

, 2013
In this article, we show that the multilevel Monte Carlo method for elliptic stochastic partial differential equations can be interpreted as a sparse grid approximation. By using this interpretation, the method can straightforwardly be generalized to any

A Lower Bound on the Altitude of the Hiroshima Firestorm Plume From Ray Optics

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Projections of nuclear winter are critically sensitive to the height of soot lofted by firestorms, yet direct observations of firestorm plumes are scarce. Here, a lower bound is established for the height of the Hiroshima firestorm plume 97 min after detonation.
