NIR/VIS Dual‐Comb Spectroscopy Comparing High and Low Repetition Rate Regimes

open access: yesLaser &Photonics Reviews, EarlyView.
This work compares dual‐comb spectroscopy at lower and higher repetition rates, emphasizing the inherent trade‐off between spectral and temporal resolution. The 80 MHz system provides high‐resolution spectra suitable for analyzing complex molecular structures, whereas the free‐running 1 GHz platform enables fast measurements for real‐time trace gas ...

Jointly Learned 3D Non‐Cartesian Sampling With Wave Encoding and Reconstruction for Neurovascular Phase Contrast MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop accelerated 3D phase contrast (PC) MRI using jointly learned wave encoding and reconstruction. Methods Pseudo‐fully sampled neurovascular 4D flow data (N = 40) and a simulation framework were used to learn phase encoding locations, wave readout parameters, and model‐based reconstruction network (MoDL) for a rapid 3D PC scan (

Characterization of Fuel Rods Supported by Dimple‐Less Spacer Grids and Subjected to Nonlinear Vibrations

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...

Bilateral Transcranial Doppler Monitoring During Neonatal Cardiac Surgery; Guidance for Clinical and Scientific Use

open access: yesPediatric Anesthesia, EarlyView.
ABSTRACT Introduction Neonates undergoing cardiac surgery face a high risk of neurological injury and neurodevelopmental complications. Transcranial Doppler monitoring is used and validated in adults to measure cerebral blood flow and can provide valuable insights into cerebral perfusion in neonates.
