Automated detection of brain abnormalities in neonatal hypoxia ischemic injury from MR images. [PDF]

, 2014
We compared the efficacy of three automated brain injury detection methods, namely symmetry-integrated region growing (SIRG), hierarchical region splitting (HRS) and modified watershed segmentation (MWS) in human and animal magnetic resonance imaging ...

Correlation tensor magnetic resonance imaging

NeuroImage, 2020
Diffusional Kurtosis Magnetic Resonance Imaging (DKI) quantifies the extent of non-Gaussian water diffusion, which has been shown to be a sensitive biomarker for microstructure in health and disease.

Whole-Body Diffusion Kurtosis Imaging [PDF]

Investigative Radiology, 2014
Diffusion kurtosis imaging (DKI) is based on a non-Gaussian diffusion model that should inherently better account for restricted water diffusion within the complex microstructure of most tissues than the conventional diffusion-weighted imaging (DWI), which presumes Gaussian distributed water molecule displacement probability.

Differentiation of placenta percreta through MRI features and diffusion-weighted magnetic resonance imaging

Insights into Imaging, 2023
Objectives To identify whether parameters measured from diffusion kurtosis and intravoxel incoherent motion help diagnose placenta percreta. Methods We retrospectively enrolled 75 patients with PAS disorders including 13 patients with placenta percreta ...

Particle Diffusion in Slow Granular Bulk Flows [PDF]

, 2012
We probe the diffusive motion of particles in slowly sheared three dimensional granular suspensions. For sufficiently large strains, the particle dynamics exhibits diffusive Gaussian statistics, with the diffusivity proportional to the local strain rate -

High‐Throughput Screening and Interpretable Machine Learning for Rational Design of Bimetallic Catalysts for Methane Activation

Advanced Science, EarlyView.
ABSTRACT Methane's efficient catalytic removal is vital for sustainable development. Bimetallic catalysts, though promising for methane activation, pose a design challenge due to their complex compositional space. This work introduces an integrated framework that combines high‐throughput density functional theory (DFT) and interpretable machine ...

Diffusion weighted imaging and diffusion kurtosis imaging in abdominal oncological setting: why and when

Infectious Agents and Cancer, 2022
This article provides an overview of diffusion kurtosis (DKI) imaging in abdominal oncology. DKI allows for more data on tissue structures than the conventional diffusion model (DWI).

Family Involvement and Financial Performance: How Do They Affect the Sustainability Commitment of Family Businesses?

Business Strategy and the Environment, EarlyView.
ABSTRACT The socio‐emotional wealth (SEW) perspective suggests that the specific priorities of a family business may make it more or less inclined to engage in sustainable practices. This paper examines how family business heterogeneity regarding family ownership, financial performance, and family board members affects the sustainability commitment of ...
