Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Best Approximation in Finite Dimensional Subspaces of L(W, V)

open access: yes, 1995
We prove Kolmogorov′s type characterization of best approximation for given L ∈ L(W, V) in finite dimensional subspace V ⊂ L(W, V). This extends the results obtained by Malbrock for the case W = V = c0 and W = C(T), V = C(S)

Comprehensive Assessment of Arterial, Tissue, and Venous Collaterals for Evaluating the Infarct Growth Rate: The Multimodal Collateral Score

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Collaterals are crucial factors that influence the infarct growth rate (IGR). We aimed to determine whether a comprehensive multimodal collateral score (MCS), incorporating collateral assessment at the arterial, tissue, and venous levels, is associated with functional independence and provides incremental prognostic value over ...

Characterization of best approximations in metric linear spaces

open access: yesAnalysis in Theory and Applications, 2003
The author provides several results on characterization of elements of best approximation by a linear subspace \(G\) in a real metric space \(X\) with translation-invariant metric \(d\). Let \(\emptyset\neq G\subset X\), \(x\in X\setminus G\), \(g_0\in G\).

Best rotated minimax approximation [PDF]

open access: yes, 1970
Thesis submitted 1970; degree awarded 1971.In this dissertation we consider the minimax approximation of functions f(x) E"C[O, l] rotated about the origin, and the characterization of the optimal rotation, a*, of f in the sense of least minimax error ...

Risk of Non‐Arteritic Anterior Ischemic Optic Neuropathy in Idiopathic Intracranial Hypertension Patients Treated with GLP‐1 Receptor Agonists

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) have demonstrated significant weight‐reducing effects and may offer benefits in idiopathic intracranial hypertension (IIH); however, recent concerns about the risk of non‐arteritic anterior ischemic optic neuropathy (NAION) have emerged.

Best mean approximation by splines satisfying generalized convexity constraints

open access: yes, 1980
A characterization of the best L1-approximation to a continuous function by classes of fixed-knot polynomial splines which satisfy generalized convexity constraints is presented and uniqueness is shown.

Clinical Impact of NOTCH3 Variant Location After First Stroke in CADASIL

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Despite its monogenic origin, Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy exhibits marked variability in clinical expression and severity. Variants in the NOTCH3 gene, within epidermal growth factor‐like repeat domains 1–6 or 7–34, are known to influence disease onset, but their impact ...

Best Approximation and Cyclic Variation Diminishing Kernels

open access: yes, 2008
where the kernel K(x, y) is Strictly Cyclic Variation Diminishing, and related problems including periodic generalized perfect splines. For various approximation problems of this type, we show the uniqueness of the best approximation and characterize the
