Aneurysm risk metrics and hemodynamics are associated with greater vessel wall enhancement in intracranial aneurysms

Royal Society Open Science, 2021
Vessel wall enhancement (VWE) in contrast-enhanced magnetic resonance imaging (MRI) is a potential biomarker for intracranial aneurysm (IA) risk stratification.

Introducing a new Trusted Research Environment - the Safe Haven Artificial Platform (SHAIP).

International Journal of Population Data Science, 2022
Objectives Scotland has an established Trusted Research Environment (TREs) through the Scottish Safe Haven Network. These Safe Havens traditionally service structured datasets, however, researchers increasingly require access to large multi-modal linked

Modified Gamma-Based Model for Solving Low Mach Number Compressible Two Phase Flows

Journal of Fluid Science and Technology, 2013
This paper presents some modifications of the gamma-based model developed by K.M. Shyue (J. Comput. Phys., 1998, 142, 208-242). In deriving process of the original model, pressure equilibrium and an isentropic condition are not involved explicitly ...

Tectonic infarct analysis: A computational tool for automated whole-brain infarct analysis from TTC-stained tissue

Heliyon, 2023
Background: Infarct volume measured from 2,3,5-triphenyltetrazolium chloride (TTC)-stained brain slices is critical to in vivo stroke models. In this study, we developed an interactive, tunable, software that automatically computes whole-brain infarct ...

A pressure-based method for solving low Mach number two-phase flows with surface tension

Journal of Fluid Science and Technology, 2015
We develop a pressure-based method using a mixture model for solving low Mach number compressible two-phase flows which contain surface tension, viscous stress, and heat conduction.

Revascularization Outcome Prediction for A Direct Aspiration-First Pass Technique (ADAPT) from Pre-Treatment Imaging and Machine Learning

Brain Sciences, 2021
A direct aspiration-first pass technique (ADAPT) has recently gained popularity for the treatment of large vessel ischemic stroke. Here, we sought to create a machine learning-based model that uses pre-treatment imaging metrics to predict successful ...

Sparse Random Signals for Fast Convergence on Invertible Logic

IEEE Access, 2021
This paper introduces sparse random signals for fast convergence on invertible logic. Invertible logic based on a network of probabilistic nodes (spins), similar to a Boltzmann machine, can compute functions bidirectionally by reducing the network energy

An Image-Based Workflow for Objective Vessel Wall Enhancement Quantification in Intracranial Aneurysms

Diagnostics, 2021
Background: VWE in contrast-enhanced magnetic resonance imaging (MRI) is a potential biomarker for the evaluation of IA. The common practice to identify IAs with VWE is mainly based on a visual inspection of MR images, which is subject to errors and ...

Lens System Adjustment in Semiconductor Lithography Equipment

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2008
In this paper, we address the problem of lens aberration adjustment for lenses of semiconductor lithography equipment. The objective of aberration adjustment is to minimize the maximum value of aberration in any part of the images that are projected on ...
