A Strong Convergence Theorem for Total Asymptotically Pseudocontractive Mappings in Hilbert Spaces
Abstract and Applied Analysis, 2012 Demiclosedness principle for total asymptotically pseudocontractive mappings in Hilbert spaces is established. The strong convergence to a fixed point of total asymptotically pseudocontraction in Hilbert spaces is obtained based on demiclosedness ...

Epimorphisms and maximal covers in categories of compact spaces
Applied General Topology, 2013 The category C is "projective complete"if each object has a projective cover (which is then a maximal cover). This property inherits from C to an epireflective full subcategory R provided the epimorphisms in R are also epi in C. When this condition fails,

Loop homology of quaternionic projective spaces [PDF]
arXiv, 2010 We determine the Batalin-Vilkovisky algebra structure of the integral loop homology of quaternionic projective spaces and octonionic projective plane.

FEBS Open Bio, EarlyView.Stem cell‐based embryo models (SCBEMs) are valuable to study early developmental milestones. Matrigel, a basement membrane matrix, is a critical substrate used in various SCBEM protocols, but its role in driving stem cell lineage commitment is not clearly defined.

Vascular endothelial‐cadherin as a marker of endothelial injury in preclinical Alzheimer disease
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1926-1940, December 2022., 2022 Abstract Objective Endothelial dysfunction is an early and prevalent pathology in Alzheimer disease (AD). We here investigate the value of vascular endothelial‐cadherin (VEC) as a cerebrospinal fluid (CSF) marker of endothelial injury in preclinical AD.

Recognizing early MRI signs (or their absence) is crucial in diagnosing metachromatic leukodystrophy
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1999-2009, December 2022., 2022 Abstract Objectives Metachromatic leukodystrophy (MLD) has characteristic white matter (WM) changes on brain MRI, which often trigger biochemical and genetic confirmation of the diagnosis. In early or pre‐symptomatic disease stages, these typical MRI changes might be absent, hampering early diagnosis.

The anterior nucleus of the thalamus plays a role in the epileptic network
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 2010-2024, December 2022., 2022 Abstract Objectives We investigated both the metabolic differences and interictal/ictal discharges of the anterior nucleus of the thalamus (ANT) in patients with epilepsy to clarify the relationship between the ANT and the epileptic network. Methods Nineteen patients with drug‐resistant epilepsy who underwent stereoelectroencephalography were studied ...

Lietuvos Matematikos Rinkinys, 1998 In this paper the problem of intrinsic normalizations of a semi-non-holonomic hypercomplexes SNGr(1, n, 2n-3) in n-dimensional projective space Pn is considered. It is proved that there exists three kinds of the intrinsic normalizations of SNGr(1, n, 2n-

Characterization of affine links in the projective space [PDF]
arXiv, 2019 A projective link is a smooth closed 1-submanifold of the real projective space of dimension three. A projective link is said to be affine if it is isotopic to a link, which does not intersect some projective plane. The main result: a projective link is affine if and only if the fundamental group of its complement contains a non-trivial element of ...
