Open AccessReproducibility of MRI-based white matter tract estimation using multi-fiber probabilistic tractography: effect of user-defined parameters and regions
There is a pressing need to assess user-dependent reproducibility of multi-fibre probabilistic tractography in order to encourage clinical implementation of these advanced and relevant approaches. The goal of ...

Open AccessIntraoperative map** of pre-central motor cortex and subcortex: a proposal for supplemental cortical and novel subcortical maps to Penfield’s motor homunculus
Penfield’s motor homunculus describes a caricaturised yet useful representation of the map of various body parts on the pre-central cortex. We propose a supplemental map of the clinically represented areas of ...

Basic features of the time finite element approach for dynamics
Very general weak forms may be developed for dynamic systems, the most general being analogous to a Hu-Washizu three-field formulation, thus paralleling well-established weak methods of solid mechanics. In thi...

Time-Finite Element Method for the Constrained Dynamics of a Rigid Body
Currently, there is a renewed interest in the study of multi-body-dynamics and its application in many fields of engineering. The mathematical model of a rigid body is useful whenever the overall motion, invol...

Multi-Body Dynamics by the Finite Element Method in Time Domain
This paper is an extension of [l], to the case of multiple rigid bodies undergoing large overall motion. The emphasis here, as in [l], is on direct formulation of weak solutions, consistent linearizations, and...

A large displacement formulation for anisotropic beam analysis
E' conveniente scomporre lo spostamento di un punto di una trave in una rototraslazione della sezione cui appartiene e in uno spostamento che deforma la sezione (in-gobbamento). Si deduce la corretta approssim...
