Bundle-specific tractogram distribution estimation using higher-order streamline differential equation

NeuroImage
Streamline tractography locally traces peak directions extracted from fiber orientation distribution (FOD) functions, lacking global information about the trend of the whole fiber bundle. Therefore, it is prone to producing erroneous tracks while missing

Reconstruction and dissection of the entire human visual pathway using diffusion tensor MRI

Frontiers in Neuroanatomy, 2010
The human visual system comprises elongated fiber pathways that represent a serious challenge for diffusion tensor imaging (DTI) and fiber tractography: while tracking of frontal fiber bundles may be compromised by the nearby presence of air-filled ...

The effect of disorder on the fracture nucleation process

, 2001
The statistical properties of failure are studied in a fiber bundle model with thermal noise. We show that the macroscopic failure is produced by a thermal activation of microcracks.

Theory Research of Curved Surface Reflection RIM-FOS under the Typical Optical Fiber Beam Structure

Chemical Engineering Transactions, 2016
This paper has completed the theoretical modeling of the cured surface reflection RIM-FOS under the typical optical fiber bundle structure. Firstly, the modeling of the fiber’s axial symmetry distribution structure is made by analytical method to get the

Cohomology of GKM fiber bundles [PDF]

Journal of Algebraic Combinatorics, 2011
The equivariant cohomology ring of a GKM manifold is isomorphic to the cohomology ring of its GKM graph. In this paper we explore the implications of this fact for equivariant fiber bundles for which the total space and the base space are both GKM and derive a graph theoretical version of the Leray-Hirsch theorem.

Soldered Bundle Background for the De Sitter Top

, 2005
We prove that the mathematical framework for the de Sitter top system is the de Sitter fiber bundle. In this context, the concept of soldering associated with a fiber bundle plays a central role. We comment on the possibility that our formalism may be of

Failure Processes in Elastic Fiber Bundles

, 2009
The fiber bundle model describes a collection of elastic fibers under load. the fibers fail successively and for each failure, the load distribution among the surviving fibers change.
