A Richardson’s Extrapolation Spreadsheet Calculator for Numerical Differentiation

Spreadsheets in Education, 2013
Even though approximating the definite differentiation by Richardson’s extrapolation method is straight forward, but its repetitive calculations are quite boring. Hence, there is a need to develop a suitable tool in teaching and learning for this method.

Simulated In‐Stream CO2 Production Under Changing Organic Carbon Quantity, Quality, and Stream Geochemistry

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 11, November 2026.
Abstract Increasing urbanization and changing precipitation confound our understanding of carbon (C) cycling in streams. Precipitation drives organic C into waterways, while watershed urbanization can increase the lability of dissolved organic carbon (DOC).

PROSWIN: Probabilistic Solar Wind Speed Forecasting Using Deep Distributional Regression From Solar Images

AGU Advances, Volume 7, Issue 8, November 2026.
Abstract Accurately predicting fast solar wind conditions is challenging, as uncertainties are large and unquantified by traditional single‐value prediction models. In particular, the risks of high‐speed solar wind streams (HSSs), which can cause damage to technological infrastructure, cannot be reliably assessed without probabilistic forecasts.

Exponentially Reduced Circuit Depths Using Trotter Error Mitigation

PRX Quantum
Product formulas are a popular class of digital quantum simulation algorithms due to their conceptual simplicity, low overhead, and performance, which often exceeds theoretical expectations. Recently, Richardson extrapolation and polynomial interpolation

Advancing Satellite Solar‐Induced Chlorophyll Fluorescence Data Assimilation in Land Surface Models: An Assessment Over Boreal Evergreen Needleleaf Forests

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 11, November 2026.
Abstract Boreal forests represent about 20% of the global forest carbon sink and contribute to climate change mitigation, yet land surface models (LSMs) struggle to simulate their gross primary production (GPP). Space‐borne observations of solar‐induced fluorescence (SIF) have been used to improve LSM GPP through data assimilation.

Dynamical Solar Wind Forecasting Using In Situ Solar Wind Speed Observations

Space Weather, Volume 24, Issue 11, November 2026.
Abstract Accurate prediction of the ambient solar wind at Earth is a key requirement for space‐weather forecasting but is limited by uncertainties in coronal boundary conditions and, to a lesser extent, heliospheric transport. We present a quantitative assessment of a solar wind forecast that uses near‐Earth in situ solar wind observations to estimate ...

Migrant frugivorous birds assist plants in tracking climate change: A first spatially explicit approach

Journal of Ecology, Volume 114, Issue 11, November 2026.
Migrant frugivorous birds can partially assist fleshy‐fruited plants fruiting during spring migration to track climate change, although severe warming and land‐cover alteration may strongly constrain seed‐dispersal range filling. Importantly, range filling capacity is uneven across plant species: differences in climatically suitable ranges and ...
