Comparison of 3‐Dimensional Ultrasound and Computed Tomography for Imaging of Abdominal Aortic Aneurysms

Journal of Ultrasound in Medicine, EarlyView.
Objectives Three‐dimensional ultrasound (3D US) is emerging as a novel imaging method for abdominal aortic aneurysms (AAAs) as it creates a low‐cost 3D AAA overview without harmful radiation and nephrotoxic contrast agents, as opposed to conventional imaging. 3D US can be used with a non‐nephrotoxic contrast agent (3D‐CEUS) for lumen delineation.

Numerical analysis of the plasma density profile of a laser wakefield accelerator using multi-objective Bayesian optimization

Machine Learning: Science and Technology
Laser wakefield acceleration (LWFA) provides a compact pathway to generate high-energy electron beams, but its performance depends on a large set of coupled, nonlinear parameters. Machine-learning approaches, particularly Bayesian optimization (BO), have

Probing warm dense matter using femtosecond X-ray absorption spectroscopy with a laser-produced betatron source

Nature Communications, 2018
Understanding the ultrafast dynamics of materials under extreme conditions is challenging. Here the authors use a femtosecond betatron X-ray source to investigate the solid to dense plasma phase transition in copper using XAS with unprecedented time ...

Posterior tibial slope measurement on lateral radiographs shows increased variability, reduced repeatability and risk of misclassification in osteoarthritic versus nonosteoarthritic knees

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The primary aim was to compare the variability and repeatability of medial posterior tibial slope (MPTS) measurements on lateral knee radiographs between osteoarthritic (OA) and non‐OA knees, and the secondary aim was to assess their implications for clinical classification.

Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan

Limnology and Oceanography: Methods, EarlyView.
Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

Coupled Environmental Effects in Competitive Inhibition of Dynamic Hydrazone Hydrogels

Macromolecular Rapid Communications, EarlyView.
Environment Alters Competitive Inhibition of Crosslinks. Ion concentration, pH, and buffer composition govern exchange kinetics and network stability in dynamic benzyl‐hydrazone hydrogels. These factors are particularly important when utilizing small‐molecule competitors for enhanced control over gel mechanics, underscoring the need to control the ...

Non‐Rigid Motion‐Compensated MR Multitasking for Free‐Breathing Low‐Dose Dynamic Contrast‐Enhanced MRI in the Abdomen

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To improve free‐breathing low‐dose quantitative dynamic contrast‐enhanced (DCE) MRI for imaging pancreatic ductal adenocarcinoma. Methods We introduced non‐rigid (NR) motion compensation (MoCo) into MR Multitasking using a novel “in‐subspace” formulation that directly applies motion fields to spatial feature maps (eigenimages ...
