Advancing Severe Plastic Deformation for Tubular Samples: Systematic Review and Machine Learning Optimization

open access: yesMetalMat, EarlyView.
This review highlights recent advancements in Severe Plastic Deformation (SPD) techniques tailored for tubular samples. The mechanisms of processing are critically discussed with emphasis on microstructural control and the governing process parameters that enable refinement to ultrafine‐ and nano‐grained structures. Comparative insights into equivalent

Ambiguities in Assigning Single‐Crystal NMR Data to Individual Atoms in the Crystal Structure: A Case Study of Hambergite, Be2$$ {}_2 $$BO3$$ {}_3 $$OH, by 9Be and 11B NMR Spectroscopy, XRD Measurements and DFT Calculations

open access: yesMagnetic Resonance in Chemistry, EarlyView.
The fundamental question of how to assign NMR resonances to specific atoms in the unit cell is addressed by using the 9Be and 11B spectra of the natural mineral hambergite as a model system. ABSTRACT The NMR interaction tensors of 9Be and 11B of hambergite, Be2$$ {}_2 $$BO3$$ {}_3 $$OH, were derived from single‐crystal NMR experiments.

Time‐Division Multiplexing for Parallel Transmission at Ultra‐High Field With Limited RF Channels

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Investigating time‐division multiplexing for parallel transmission in ultra high‐field imaging, striving for homogeneous whole brain excitation with a limited number of RF channels. Methods A fast RF switch was built to alternately route 8 transmit channels to each row of a double‐row 16‐element transmit coil array at a 9.4 T human MRI

Large Deformation Pile‐soil Interaction Under Lateral Vehicle Impact Using Hybrid SPH+FEM and EFG+FEM Models

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...

Growing trees on farms: Navigating the goals and values of farmers

open access: yesPeople and Nature, EarlyView.
Abstract Agricultural landscapes represent critical contexts for advancing policy objectives related to tree cover expansion. This paper explores how farmers' values influence their willingness or ability to grow trees on farms. Research is based on 49 interviews and two focus groups with farmers in England and draws on two social science research ...
