Modelling Climate‐Resilient Habitats for Conservation and Restoration of Isoberlinia doka Craib and Stapf and Isoberlinia tomentosa (Harms) Craib and Stapf in Benin

Climate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
Despite having similar climatic niches, woody plant species can exhibit contrasting responses to climate change. Using MaxEnt and spatial prioritization, we evaluated Isoberlinia doka and I. tomentosa under future climate scenarios (2041–2060). Despite high niche overlap (D = 0.635; I = 0.788), I. doka experienced severe habitat contraction, whereas I.

Diagnosing Forecast Error Propagation and Large‐Scale Dynamics of Weather Extremes With an AI Weather Model

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Artificial intelligence (AI) weather models can generate fast and accurate weather forecasts, yet they still struggle to predict regional extremes. Exploring error propagation pathways and associated large‐scale dynamics is essential for understanding extreme weather drivers and AI model performance.

Integrated Sensing and Communication in a Fiber‐Wireless System With Time‐Phase Synthesis Dimension Waveform

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
A unified fiber‐wireless integrated sensing and communication system is enabled by a single microwave photonic platform with a time‐phase synthesis dimension waveform. This architecture simultaneously delivers high‐speed data transmission, high‐precision wireless ranging, and accurate fiber diagnostics over a high‐power analog radio‐over‐fiber link ...

The discrete charm of iterated function systems. A computer scientist's perspective on approximation of IFS invariant sets and measures

CoRR
We study invariant sets and measures generated by iterated function systems defined on countable discrete spaces that are uniform grids of a finite dimension. The discrete spaces of this type can be considered as models of spaces in which actual numerical computation takes place. In this context, we investigate the possibility of the application of the

THE RANDOM ITERATION ALGORITHM [PDF]

In the last decades, many researchers concerned their attention on fractals properties of objects. Fractals can be use to describe natural shapes so their applications are various in many fields such as informatics, economics, engineering, medical ...

Gradient‐Boosted Mixture Regression Models for Postprocessing Ensemble Weather Forecasts

Environmetrics, Volume 37, Issue 6, September 2026.
ABSTRACT Nowadays, weather forecasts are based on ensemble forecasts which originate from multiple runs of numerical weather prediction models. However, such forecasts are usually miscalibrated and/or biased, thus requiring statistical postprocessing. Non‐homogeneous regression models, such as ensemble model output statistics, are frequently applied to

How Good Is Your Forecast? The Importance of User‐Centred, Decision‐Relevant Evaluation of Forecasts and Climate Services

Meteorological Applications, Volume 33, Issue 5, September/October 2026.
Example of a probabilistic seasonal river flow forecast, compared to decision‐relevant drought thresholds and observed river flow, and used as part of a user‐centred co‐evaluation workshop. This paper presents a user‐centred framework for evaluating forecasts and climate services, combining participatory approaches, event‐based contingency tables and ...
