A 1D continuum model for beams with pantographic microstructure: asymptotic micro-macro identification and numerical results [PDF]
, 2018 In the standard asymptotic micro-macro identification theory, starting from a De Saint-Venant cylinder, it is possible to prove that, in the asymptotic limit, only flexible, inextensible, beams can be obtained at the macro-level.

Remote Assessment of Ataxia Severity in SCA3 Across Multiple Centers and Time Points
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Spinocerebellar ataxia type 3 (SCA3) is a genetically defined ataxia. The Scale for Assessment and Rating of Ataxia (SARA) is a clinician‐reported outcome that measures ataxia severity at a single time point. In its standard application, SARA fails to capture short‐term fluctuations, limiting its sensitivity in trials.

Prediction of Running-in Behavior for Point Contacts under Mixed Lubrication [PDF]
AUT Journal of Mechanical EngineeringTribology concentrates on wear, lubrication, and friction of interacting surfaces in relative motion. Wear, which is the major reason of material dissipation, evolves in three separate stages: severe wear, steady-state, and running-in.

Continuum damage mechanics for the lithosphere [PDF]
Journal of Geophysical Research, 2011 [1] This paper introduces a new mathematical formulation of continuum damage mechanics for deep lithospheric layers subjected to thermomechanical loading. The material's rheology includes isotropic linear elasticity as well as nonlinear viscoplasticity induced by combined creep mechanisms.

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 ...
