Abnormal lymphatic system function in patients with chronic neck and shoulder pain: neuroimaging evidence from DTI-ALPS [PDF]

open access: yesFrontiers in Molecular Neuroscience
ObjectiveChronic neck and shoulder pain (CNSP) is frequently associated with structural and functional brain damage that progressively worsens over time.

Parametric models analysed with linear maps

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2020
Parametric entities appear in many contexts, be it in optimisation, control, modelling of random quantities, or uncertainty quantification. These are all fields where reduced order models (ROMs) have a place to alleviate the computational burden ...

Tensor clustering on outer-product of coefficient and component matrices of independent component analysis for reliable functional magnetic resonance imaging data decomposition

open access: yesJournal of Neuroscience Methods, 2019
Stability of spatial components is frequently used as a post-hoc selection criteria for choosing the dimensionality of an independent component analysis (ICA) of functional magnetic resonance imaging (fMRI) data. Although the stability of the ICA temporal courses differs from that of spatial components, temporal stability has not been considered during

On density and dentability in Hilbert spaces

open access: yesScientific African
This paper establishes necessary and sufficient conditions for density and dentability in infinite-dimensional complex Hilbert spaces, demonstrating their fundamental connections to operator theory and optimization through a synthesis of spectral ...

On Deformed-Metric Equivalence of Hilbert Space Operators

open access: yesJambura Journal of Mathematics
This paper introduces and studies a novel class of equivalence relations in operator theory, called deformed-metrically equivalent operators. Two operators S and T in B(H) are said to be deformed-metrically equivalent if there exists a positive operator ...

Tensor Products in Quantum Functional Analysis: the Non-Matricial Approach

open access: yes, 2006
As is known, there exists an alternative, "non-matricial" way to present basic notions and results of quantum functional analysis (= operator space theory). This approach is based on considering, instead of matrix spaces, a single space, consisting, roughly speaking, of vectors from the initial linear space equipped with coefficients taken from some ...
