Experimental study on dynamic stability of rubber-cement composites by SHPB and high-speed slicing [PDF]

Archives of Civil Engineering, 2022
Improper disposal of waste tires will not only bring environmental impact and safety risks but also cause a serious waste of resources. In the field of civil engineering materials, waste tire particles are used as a substitute for non-renewable ...

Ischemic Brain Slice Glucose Utilization: Effects of Slice Thickness, Acidosis, and K⁺ [PDF]

Journal of Cerebral Blood Flow & Metabolism, 1991
Brain slices of varying thickness were used to modify retention of metabolic products in an in vitro model of ischemia. Past and present results reveal increased anaerobic glycolysis in 660-μm slices with accumulation of lactate as slice thickness reaches 1,000 μm. Brain slice glucose utilization and lactate content were measured in buffers of various

Velocity statistics from spectral line data: effects of density-velocity correlations, magnetic field, and shear [PDF]

, 2003
In a previous work Lazarian and Pogosyan suggested a technique to extract velocity and density statistics, of interstellar turbulence, by means of analysing statistics of spectral line data cubes.

Clusters and Superclusters in the Las Campanas Redshift Survey [PDF]

, 2003
Two-dimensional high-resolution density field of galaxies of the Las Campanas Redshift Survey (LCRS) with a smoothing length 0.8 Mpc/h is used to extract clusters and groups of galaxies, and a low-resolution field with a smoothing length 10 Mpc/h to find

Automatic 3D bi-ventricular segmentation of cardiac images by a shape-refined multi-task deep learning approach [PDF]

, 2019
Deep learning approaches have achieved state-of-the-art performance in cardiac magnetic resonance (CMR) image segmentation. However, most approaches have focused on learning image intensity features for segmentation, whereas the incorporation of ...

Dextran Decreases Extracellular Tortuosity in Thick-Slice Ischemia Model [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2000
An unexpected decrease of extracellular space (ECS) tortuosity was recently reported in thick (1000 μm) ischemic slices using radiotracers. The current study shows that the tortuosity in thick slices from rat neocortex can increase or decrease depending on experimental conditions, whereas ECS volume fraction remains diminished to approximately 10 ...

Extending Velocity Channel Analysis for Studying Turbulence Anisotropies [PDF]

, 2016
We extend the velocity channel analysis (VCA), introduced by Lazarian & Pogosyan, of the intensity fluctuations in the velocity slices of position-position-velocity (PPV) spectroscopic data from Doppler broadened lines to study statistical anisotropy of ...

Interpolation-based super-resolution reconstruction: effects of slice thickness [PDF]

Journal of Medical Imaging, 2014
Standard clinical magnetic resonance imaging (MRI) is acquired in two-dimensions where the in-plane resolution is higher than the slice select direction. These acquisitions include axial, coronal, and sagittal planes. To date, there have been few attempts to combine the information of these three orthogonal orientations.

Pragmatic approaches to reducing radiation dose in brain computed tomography scan using scan parameter modification

Journal of Medical Signals and Sensors, 2022
Background: High radiation dose of patients has become a concern in the computed tomography (CT) examinations. The aim of this study is to guide the radiology technician in modifying or optimizing the underlying parameters of the CT scan to reduce the ...
