Cervical Spinal Cord Magnetization Transfer Ratio and Its Relationship With Clinical Outcomes in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The cervical spinal cord (cSC) is highly relevant to clinical dysfunction in multiple sclerosis (MS) but remains understudied using quantitative magnetic resonance imaging (MRI). We assessed magnetization transfer ratio (MTR), a semi‐quantitative MRI measure sensitive to MS‐related tissue microstructural changes, in the cSC and its ...

Harmonic foliations on a complex projective space [PDF]

open access: yesTsukuba Journal of Mathematics, 1990
In 1970, D. Ferus [6] gave an estimation on the codimension of a totally geodesic foliationon a sphere and a complex projective space, and successively P. Dombrowski [1] improved his results. Moreover, R. Escobales classified Riemannian foliationssatisfying a certain condition on a sphere and a complex projective space in a series of his papers [2], [3]

Correlation Between Irisin and Cognitive Functions in Alzheimer Dementia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The myokine irisin, a recent positive mediator of exercise in the brain, shows neuroprotective functions against Alzheimer's disease (AD). The association between irisin and cognition has never been explored in a biologically defined cohort of patients.

A Classification of Compact Cohomogeneity One Locally Conformal Kähler Manifolds

open access: yesMathematics
In this paper, we apply a result of the classification of a compact cohomogeneity one Riemannian manifold with a compact Lie group G to obtain a classification of compact cohomogeneity one locally conformal Kähler manifolds.

Toric polar maps, normal crossings and mixed volumes

open access: yesComptes Rendus. Mathématique
Given a hypersurface in a complex projective space, we prove that the Chern–Schwartz–MacPherson class of a certain open set, namely the complement of the union of the hypersurface and the coordinate hyperplanes, is given (up to sign) by the multidegrees ...

Purity and hybridness of two tensors on a real hypersurface in complex projective space

open access: yesOpen Mathematics
On a real hypersurface MM in complex projective space, we can define two tensor fields of type (1, 2), AF(k){A}_{F}^{\left(k)} and AT(k){A}_{T}^{\left(k)}, associated with the shape operator AA of the real hypersurface, for any nonnull real number kk ...

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.
