Forecasting Natural Gas Prices in Real Time
Journal of Applied Econometrics, Volume 41, Issue 2, Page 139-155, March 2026.ABSTRACT This paper provides a comprehensive analysis of the forecastability of the real price of natural gas in the United States at the monthly frequency considering a universe of models that differ in complexity and economic content. We find that considerable reductions in mean‐squared prediction error relative to a no‐change benchmark can be ...

Joint distribution of Hecke eigenforms on H3$ \mathbb {H}^3$
Mathematische Nachrichten, Volume 299, Issue 3, Page 661-674, March 2026.Abstract We prove a joint value equidistribution statement for Hecke–Maaß cusp forms on the hyperbolic three‐space H3$\mathbb {H}^3$. This supports the conjectural statistical independence of orthogonal cusp forms.

Random Structures &Algorithms, Volume 68, Issue 2, March 2026.ABSTRACT We study the contact process on the long‐range percolation cluster on ℤ$$ \mathbb{Z} $$ where each edge ⟨i,j⟩$$ \left\langle i,j\right\rangle $$ is open with probability |i−j|−s$$ {\left|i-j\right|}^{-s} $$ for s>2$$ s>2 $$. Using a renormalization procedure, we apply the Peierls‐type argument to prove that the contact process dies out if the ...

Methodological Frameworks for Computational Electrocatalysis: From Theory to Practice
Small Methods, Volume 10, Issue 5, 9 March 2026.Computational modeling is widely used to investigate electrocatalytic reactions, yet accurately describing electrochemical interfaces remains challenging. This review outlines theoretical and computational strategies, based on density functional theory, to model reaction thermodynamics, solvation effects, applied bias, and kinetics.

A Comparison of Monte Carlo Based Marginal Likelihood Estimators
WIREs Computational Statistics, Volume 18, Issue 1, March 2026.Comparison of marginal likelihood estimation methods. ABSTRACT Marginal likelihood plays a central role in Bayesian model comparison and hypothesis testing, but its computation is often challenging in practice. This article reviews recent Monte Carlo methods that rely on the availability of Markov chain Monte Carlo (MCMC) samples from the posterior and

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract We investigate how mineral dissolution reshapes flow pathways and solute transport in three‐dimensional discrete fracture networks using a computationally efficient graph‐based reactive transport model. The DFNs are inspired by field‐site observations of fractured carbonate and represent realistic connectivity and structural heterogeneity ...

Trading Zones Between Thick and Thin: Anthropological Description as Scaffold or Mosaic
American Anthropologist, Volume 128, Issue 1, Page 159-170, March 2026.ABSTRACT Referring to the work of historian of science Peter Galison, I argue that anthropology requires thin description as an essential counterpart for thick description. Thin accounts provide the scaffolding within which thick descriptions sit. Galison uses the idea of a “trading zone” connecting different communities who, despite their differences (

Toward Psychometric Learning Analytics: Augmenting the Urnings Algorithm with Response Times
Journal of Educational Measurement, Volume 63, Issue 1, Spring 2026.Abstract Adaptive learning systems (ALS) aim to tailor the educational material to match the student's needs, ultimately improving the learning outcomes. An ALS dynamically adjust the level of practice based on the student's ability; therefore, obtaining accurate ability estimates is crucial.

Cointegrating Polynomial Regressions With Power Law Trends
Journal of Time Series Analysis, Volume 47, Issue 2, Page 331-344, March 2026.ABSTRACT The common practice in cointegrating polynomial regressions (CPRs) often confines nonlinearities in the variable of interest to stochastic trends, thereby overlooking the possibility that they may be caused by deterministic components. As an extension, we propose univariate and multivariate CPRs that incorporate power law deterministic trends.

Brownian Motion With Partial Resetting Conditioned to Stay Positive
Bulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.Abstract We consider Brownian motion with partial resetting, which has recently attracted a lot of attention in physics as well as the mathematics literature. We analyze the speed of convergence of this process towards stationarity as well as its quasistationary behavior.
