Diffusion Spectrum Imaging Maps Early Axonal Loss and a Unique Progressive Signal in Neuronal Intranuclear Inclusion Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To delineate specific in vivo white matter pathology in neuronal intranuclear inclusion disease (NIID) using diffusion spectrum imaging (DSI) and define its clinical relevance. Methods DSI was performed on 42 NIID patients and 38 matched controls.

Two-phase densification of cohesive granular aggregates [PDF]

, 2001
When poured into a container, cohesive granular materials form low-density, open granular aggregates. If pressed upon with a ram, these aggregates densify by particle rearrangement.

On the gravity flow of granular materials

International Journal of Mechanical Sciences, 1982
Abstract The governing equations for flow of an incompressible and cohesionless material are solved approximately by a new procedure. In this procedure the equilibrium equations and the yield criterion are satisfied identically through invocation of the Airy stress function and the Sokolovski functions. The problem analysed pertains to radial flow in

Time-dependent unified hardening model for granular materials

Yantu gongcheng xuebao, 2019
In recent years, the construction of regional airports in mountainous areas is increasing. The high-fill engineering projects have large fill volume and use local materials, which contain soil, sand, rockfill materials and other geotechnical materials ...

Impact of Asymptomatic Intracranial Hemorrhage on Outcome After Endovascular Stroke Treatment

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Endovascular treatment (EVT) achieves high rates of recanalization in acute large‐vessel occlusion (LVO) stroke, but functional recovery remains heterogeneous. While symptomatic intracranial hemorrhage (sICH) has been well studied, the prognostic impact of asymptomatic intracranial hemorrhage (aICH) after EVT is less certain ...

Design and construction aspects of a geocomposite drainage system in a dam [PDF]

, 2012
The drainage system of a dam depends mainly of the available granular material founded near the dam site and it’s quantities. In some cases, the use of natural granular materials can reach an impracticable cost considering the transportation and the ...

Velocity correlations in granular materials

, 1998
A system of inelastic hard disks in a thin pipe capped by hot walls is studied with the aim of investigating velocity correlations between particles. Two effects lead to such correlations: inelastic collisions help to build localized correlations, while ...

3D MULTI-SCALE SEGMENTATION OF GRANULAR MATERIALS

Image Analysis and Stereology, 2011
On a microscopic scale, a pyrotechnic material is made of a polymer matrix containing grains with different sizes and shapes. Its physical behaviour can be predicted by homogenization.

Spatial and Volumetric Characteristics of Glioblastoma: Associations With Clinical Presentation and Survival

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We aim to comprehensively analyze how regional tumor and edema characteristics are associated with clinical presentations and survival outcomes in a large cohort of glioblastoma patients. Methods Patients with IDH‐wildtype glioblastoma who received brain MRI from 2010 to 2023 were included.
