Model-Based Bootstrapping on Classified Tensor Morphologies: Estimation of Uncertainty in Fibre Orientation and Probabilistic Tractography. [PDF]

In this study, fast and clinically feasible model-based bootstrapping algorithms using a geometrically constrained two-tensor diffusion model are employed for estimating uncertainty in fibre-orientation. Voxels are classified based on tensor morphologies

Tensor products of algebras

, 2022
Naloga se ukvarja s tenzorskimi produkti in njihovo uporabo pri študiju algeber. Predvsem se osredotočimo na centralne enostavne algebre. Iz lastnosti tenzorskega produkta na takih algebrah sledijo mnogi zanimivi izreki.The thesis deals with tensor ...

Representing matrices, M-ideals and tensor products of L1-predual spaces

Extracta Mathematicae, 2018
Motivated by Bratteli diagrams of Approximately Finite Dimensional (AF) C* - algebras, we consider diagrammatic representations of separable L1 -predual spaces and show that, in analogy to a result in AF C* -algebra theory, in such spaces, every M-ideal ...

Infinite tensor products of Banach spaces I [PDF]

, 1978
In this paper we construct a new class of infinite tensor product Banach spaces. We call them spaces of type v since they are constructed in a manner which closely parallels von Neumanns construction of infinite tensor products of Hilbert spaces.

Tensor ranks for the inversion of tensor-product binomials

Journal of Computational and Applied Mathematics, 2010
The author proves that if a nonsingular matrix \(A\) of order \(n=pq\) is a tensor-product binomial with two factors then the tensor rank of \(A^{ - 1}\) is bounded from above by min\(\{p,q\}\). The estimate is sharp, and in the worst case it amounts to \(\sqrt n\).

Tensor product of f-rings

Positivity, 2020
In this paper we prove that $\ell$-group tensor product of archimedean $f$-rings is an $f$-ring. We will use this result to characterize multiplicative $\ell$-bimorphisms between unital $f$-rings.

Structural Adaptive Smoothing in Diffusion Tensor Imaging: The R Package dti [PDF]

Diffusion weighted imaging has become and will certainly continue to be an important tool in medical research and diagnostics. Data obtained with diffusion weighted imaging are characterized by a high noise level.

Symmetry Transformations on the Set of Tensor Products of Rank-1 Idempotents

Journal of Mathematics
We obtain a characterization of bijective maps preserving the trace of products on the set of tensor products of rank-1 idempotents, which may be considered as a generalization of Molnár’s Wigner-type theorem in multipartite systems.

Spatio-Temporal Multiway Data Decomposition Using Principal Tensor Analysis on k-Modes: The R Package PTAk [PDF]

The purpose of this paper is to describe the R package {PTAk and how the spatio-temporal context can be taken into account in the analyses. Essentially PTAk() is a multiway multidimensional method to decompose a multi-entries data-array, seen ...
