Reference charts for first‐trimester placental three‐dimensional fractional moving blood volume derived using OxNNet

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 2, Page 191-200, February 2026.
ABSTRACT Objective To establish a comprehensive reference range for first‐trimester placental three‐dimensional (3D) single‐vessel fractional moving blood volume (svFMBV) using the OxNNet toolkit, based on values observed in healthy pregnancies.

Mesh, Hydrodynamic Boundary, and Uncertainty Analysis of the 2D‐SWEs: Taking Numerical Simulation of River Networks as an Example

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Targeting the issues of insufficient predictive ability and inefficient computation in two‐dimensional shallow water equations (2D‐SWEs), this study deeply couples the mesh and hydrodynamic boundary, constructing multiple 2D hydrodynamic models (run 2,640 times).

Gradual pollen release in a buzz‐pollinated plant: Investigating pollen presentation theory under bee visitation

open access: yesFunctional Ecology, Volume 40, Issue 2, Page 476-485, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The rate at which flowers dispense pollen across successive pollinator visits is a key functional trait influencing male reproductive success. Pollen presentation theory (PPT) predicts that when pollinators are abundant and actively groom their bodies to collect pollen,

Integrating AI models into ecological research workflows: The case of terrestrial bioacoustics

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 2, Page 257-271, February 2026.
Abstract Data collected by autonomous sensors, including camera traps and acoustic recorders, have enormous potential to generate new scientific insights in ecology and related fields. Modern machine learning and AI classification methods are critical to analysing these often immense data streams.

Location, Location, Location: Monazite Behaviour During UHT Metamorphism and Melt Crystallization

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 2, Page 158-175, February 2026.
ABSTRACT Monazite is a robust mineral for recording the suprasolidus evolution of migmatites and granulites. However, monazite commonly has diverse compositions and yields variable dates in a single sample; understanding the controls on monazite behaviour and composition during partial melting and melt crystallization are not always straightforward ...

Looking Back to 1991 Economic Forecasting: Introducing Cointegration

open access: yesOxford Bulletin of Economics and Statistics, Volume 88, Issue 1, Page 1-21, February 2026.
ABSTRACT Originally written in 1991 to advance the formal analysis of macroeconomic forecasting models and methods following the development of cointegration, alternative forecasting devices, conditional and unconditional forecasts, and data accuracy are considered.

Evidence for Virtual Source‐Receiver Refractions in Cross Correlations of Infrasonic Ambient Noise

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Seasonal variability in source activity and atmospheric temperature were retrieved from 11 years of infrasonic ambient noise. Variable lag times between an array and single microbarometer were obtained from envelopes of cross‐correlation functions. Beamforming and one‐bit normalization significantly enhanced the stationary phase.
