Failure after operative repair is higher for ballistic femoral neck fractures than for closed, blunt-injury fractures: a multicenter retrospective cohort study

Trauma Surgery & Acute Care Open
Introduction The purpose of this study was to describe the outcomes after operative repair of ballistic femoral neck fractures. To better highlight the devastating nature of these injuries, we compared a cohort of ballistic femoral neck fractures to a ...

Toward Optimized Intravoxel Incoherent Motion (IVIM) and Compartmental T2 Mapping in Abdominal Organs

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To quantitatively assess the bias in the intravoxel incoherent motions (IVIM)–derived pseudo‐diffusion volume fraction (f) caused by the differences in relaxation times between the tissue and fluid compartments, and to develop a two‐dimensional (b‐value‐TE) fitting approach for simultaneous T2 and IVIM parameter estimation along with ...

Research on ballistic performance of green shear thickening functionalized fabric based on solid waste modification

Materials & Design
Based on the solid waste-based modification, green shear-thickening functionalized ballistic composites were prepared. Silica aerosols were obtained from solid waste diatomaceous earth through sol–gel preparation, gel aging, and supercritical drying. The

Simulation‐Informed Evaluation of Microvascular Parameter Mapping for Diffusion MR Imaging of Solid Tumours

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose We aim to inform the design of new diffusion MRI (dMRI) approaches for microvasculature quantification that enhance the biological specificity of imaging towards cancer. Methods We adopted simulation‐informed modelling of the vascular dMRI signal. We synthesised signals from 1500 synthetic vascular networks, for a variety of protocols (

Motion‐Compensated Diffusion Imaging With Phase‐Contrast for Robust Quantification of Regional Cerebral Blood Flow

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate a motion‐compensated diffusion imaging with phase‐contrast (MC‐DIP) technique for mitigating errors in regional cerebral blood flow (rCBF) quantification caused by physiological brain motion. Methods Diffusion‐weighted images were acquired in 11 healthy volunteers on a 3.0 T MRI system using three gradient ...

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...
