Population dynamics, survival, and movements of Texas tortoises in a national park in southern Texas
The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.Texas tortoise abundance in a small national park in South Texas, USA, declined by >25%, from an estimated 273 tortoises in 2014 to 204 tortoises in 2024. The severity of the decline varied across survey units, but abundance remained highest in areas having greater canopy cover and experiencing less invasion by Guinea grass.

Eminence Grise Coalitions: On the Shaping of Public Opinion
, 2014 We consider a network of evolving opinions. It includes multiple individuals with first-order opinion dynamics defined in continuous time and evolving based on a general exogenously defined time-varying underlying graph.

Hidden Markov Models for Bounded, Inflated Time Series: Forecasting Icing on Wind Turbine Blades
Wind Energy, Volume 29, Issue 5, May 2026.ABSTRACT Time series analysis of icing‐induced power loss in wind turbines pose several challenges: the response is bounded, serially dependent, intermittently missing, highly dispersed, and often inflated at a single value. We address these challenges with discrete‐time hidden Markov models for a discrete‐continuous process assumed to follow a mixture

Fuel Cells, Volume 26, Issue 2, April 2026.ABSTRACT Prognostics and health management are crucial for the reliability and lifetime assessment of polymer electrolyte fuel cells (PEFCs). Here, we review the current advances on this topic, focusing mainly on key degradation mechanisms and methodologies such as physics‐aware, data‐driven, and hybrid modeling approaches.

Integrable Floquet dynamics, generalized exclusion processes and "fused" matrix ansatz
, 2018 We present a general method for constructing integrable stochastic processes, with two-step discrete time Floquet dynamics, from the transfer matrix formalism. The models can be interpreted as a discrete time parallel update.

Monitoring Groundwater Pumping Using Time‐Lapse Tomography From Ambient Seismic Noise
Water Resources Research, Volume 62, Issue 4, April 2026.Abstract Management of water resources will be of critical importance as the effects of climate change accelerate. This implies the need to monitor water resources with high spatial and temporal resolution. One way to meet this need could be passive seismic methods using ambient seismic noise. In this study, we present a novel approach using time‐lapse

Continuous data assimilation for the Richards equation of unsaturated flow: A computational study
Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.Abstract Azouani–Olson–Titi data assimilation (often referred to as AOT, after its authors) is a computationally‐efficient algorithm that has been shown analytically and computationally to recover the true solution for a wide variety of regimes exponentially fast in time, in addition to being robust with respect to noisy data, stochastic forcing, and ...

Sequential Reservoir Computing for Log File‐Based Behavior Process Data Analyses
Journal of Educational Measurement, Volume 63, Issue 1, Spring 2026.Abstract The use of process data in assessment has gained attention in recent years as more assessments are administered by computers. Process data, recorded in computer log files, capture the sequence of examinees' response activities, for example, timestamped keystrokes, during the assessment.

Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Understanding the mixing of groundwater age and of nonpoint source (NPS) pollutants in water samples is crucial for interpreting age tracer and NPS pollutant data from production wells. Traditionally, diffusion and mechanical dispersion have been key mixing processes embedded in physical models for simulating and interpreting age tracer and ...
