Analysis of nonlinear systems using ARMA (autoregressive moving average) models
, 1990 While many vibration systems exhibit primarily linear behavior, a significant percentage of the systems encountered in vibration and model testing are mildly to severely nonlinear.

Water Resources Research, Volume 62, Issue 6, June 2026.Abstract Frozen ground, including permafrost and seasonally frozen ground (SFG), is a critical element of the cryosphere that strongly regulates hydrological processes in cold regions. It has been debated whether frozen ground degradation will make landscapes more, or less, sensitive to precipitation inputs; either outcome has profound implications for

On the Role of Electron Precipitation in Excess Radiation Doses Measured at Aviation Altitudes
Space Weather, Volume 24, Issue 6, June 2026.Abstract Radiation from space in the form of galactic cosmic rays (GCRs) generates a persistent background of ionizing radiation in Earth's atmosphere. The dose rate of ionizing radiation due to GCRs increases from sea level to aviation altitudes.

Using ARMA Models in Stochastic Enterprise Valuation
This article presents a method for estimating the variance of the firm or enterprise value distribution by incorporating temporal dependencies in cash flows using ARMA models.

Functional Ecology, Volume 40, Issue 6, Page 1709-1724, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Phosphorus (P) limitation may intensify plant competition. However, in severely P‐impoverished soils of south‐western Australia, cluster‐rooted Banksia attenuata (Proteaceae) can facilitate P acquisition of neighbouring species by mobilising tightly bound P from soil ...

Robust Simulation-Based Estimation of ARMA Models
, 2001 This article proposes a new approach to the robust estimation of a mixed autoregressive and moving average (ARMA) model. It is based on the indirect inference method that originally was proposed for models with an intractable likelihood function.

Digestive Endoscopy, Volume 38, Issue 6, June 2026.ABSTRACT Background Endoscopic anti‐reflux therapies, including anti‐reflux mucosectomy (ARMS) and mucosal ablation (ARMA), offer minimally invasive treatment for gastroesophageal reflux disease (GERD) but carry risks of stenosis and delayed bleeding.

Bayesian Analysis of ARMA Models
Root cancellation in Auto Regressive Moving Average (ARMA) models leads tolocal non-identification of parameters. When we use diffuse or normal priorson the parameters of the ARMA model, posteriors in Bayesian analyzes show ana posteriori favor for this ...
