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.

3D CONTACT PROBLEM ON INTERACTION BETWEEN FLEXIBLE WEDGE AND TWO PUNCHES UNDER FRICTION

Advanced Engineering Research, 2012
The spatial contact problem for the flexible wedge is investigated in the quasi-static formulation when two identical elliptic rigid punches are symmetrically impressed into one face of the wedge under friction. The other wedge face is stress-free.

The Physically Nonlinear Analysis of Circular Plate on Deformable Foundation

The Baltic Journal of Road and Bridge Engineering, 2011
A circular reinforced concrete plate on deformable foundation is investigated. The foundation is composed of three layers of soil which are defined as isotropically nonlinear materials with variable physical properties. The reinforced plate is treated as

A contact‐stabilized Newmark method for dynamical contact problems [PDF]

International Journal for Numerical Methods in Engineering, 2007
AbstractThe numerical integration of dynamical contact problems often leads to instabilities at contact boundaries caused by the non‐penetration condition between bodies in contact. Even an energy dissipative modification (see, e.g. (Comp. Meth. Appl. Mech. Eng. 1999; 180:1–26)), which discretizes the non‐penetration constraints implicitly, is not able

Prevalence of Systemic Lupus Erythematosus in Australia, 2010–2022: A Population‐Based Study Using Linked National Administrative Health Data

Arthritis Care &Research, EarlyView.
Objective Systemic lupus erythematosus (SLE) is a heterogenous inflammatory condition with widely varying global prevalence estimates. The frequency of SLE in the general population of Australia has been reported to be notably lower than contemporary estimates in countries such as the United States or United Kingdom, at 19 to 39 per 100,000 as opposed ...

A nonlocal parabolic system with application to a thermoelastic problem

International Journal of Mathematics and Mathematical Sciences, 1999
A system modeling the thermoelastic bards contacts is studied. The problem is first transformed into an equivalent nonlocal parabolic systems using a transformation, and then the existence and uniqueness of the solutions are demonstrated via the ...
