Charting the Normal Development of Structural Brain Connectivity in Utero Using Diffusion MRI

Human Brain Mapping, Volume 47, Issue 14, October 1, 2026.
This study proposes new methods to study the development of the structural connectivity in utero using diffusion‐weighted MRI. The methods are applied on data from around 200 fetal brains to chart how the structural connectome develops between 22 and 37 gestational weeks.

Unveiling Functional‐Metabolic Synergy in the Healthy Brain: Multivariate Integration of Dynamic [18F]FDG‐PET and Resting‐State fMRI

Human Brain Mapping, Volume 47, Issue 14, October 1, 2026.
ABSTRACT Despite accounting for only 2% of body weight, the human brain requires significant amounts of glucose, even at rest, underscoring the importance of functional‐metabolic relationships. Previous studies revealed moderate associations between resting‐state fMRI functional connectivity (FC) and local metabolism via [18F]FDG‐PET, yet much remains ...

A Novel Non‐Torque Dynamic Load Decoupling Method for Large Wind Turbine Nacelle Test Bench

Wind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT Accurate reproduction of non‐torque dynamic loads is a key challenge for full‐scale wind turbine nacelle test benches, where the nacelle‐level drivetrain is validated under controlled multi‐degree‐of‐freedom mechanical loading. This study focuses on the shaft‐conjugate load application unit (LAU) adopted in the 25‐MW‐class full‐scale wind ...

Simulator‐Based Bayesian Inference of Enhanced Geothermal Reservoir Properties

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Inversions of dynamic multi‐scale multi‐physics subsurface system properties rely on the effective sampling of high‐dimensional parameter spaces and are thus notoriously difficult to perform. The associated models are defined by complex nonlinear relationships with potentially stochastic components, which lead to analytically intractable ...

Rethinking the Oligodendrocyte Progenitor Cell: One Cell, Many Functions

European Journal of Neuroscience, Volume 64, Issue 7, October 2026.
Oligodendrocyte progenitor cells (OPCs) are increasingly recognised as multifunctional CNS cells rather than mere precursors of myelinating oligodendrocytes. Alongside myelination and remyelination, they contribute to myelin and circuit plasticity, circuit regulation, vascular and blood–brain barrier regulation and neuroimmune modulation.

Controversies in NEN: An ENETS position statement on the role of liver transplantation (LT) in patients with advanced small‐intestinal and pancreatic NETs

Journal of Neuroendocrinology, Volume 38, Issue 10, October 2026.
Abstract Liver transplantation (LT) may offer survival or symptomatic benefit for highly selected patients with advanced, well‐differentiated small‐intestinal or pancreatic neuroendocrine tumours and unresectable liver‐dominant metastases. However, its role remains controversial, as LT is rarely curative, recurrence is common, and benefits must be ...

Multiphysics Simulation of Positive Streamer Discharge in Air Using Finite Element Method

International Journal for Numerical Methods in Engineering, Volume 127, Issue 18, 30 September 2026.
ABSTRACT Streamer discharge modeling by means of the Finite Element Method (FEM) presents a formidable challenge in computational physics due to its nonlinear and convection‐dominated characteristics that cause numerical instabilities, including negative densities of charged particles.
