Chebychev coefficients in approximation of powers of x

Journal of Approximation Theory, 1990
The author makes use of studies by himself and others on the behavior of generalized polynomials and in particular, oscillating generalized polynomials, in order to obtain estimates on \(E_ n(\alpha)\) and \(E_ n'(\alpha)\) the degree of approximation of \(x^{\alpha}\), \(\alpha>0\), by means of polynomials of degree \(\leq n\) and by means of such ...

Characterizing Cutaneous α‐Synuclein Deposition and Seeding Activity in Parkinson's Disease Subtypes

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cutaneous phosphorylated α‐synuclein (p‐syn) and α‐synuclein seeding activity are promising biomarkers for Parkinson's disease (PD), but their clinical value remains uncertain due to disease heterogeneity. This study evaluates these two biomarkers in PD patients to inform phenotype‐specific diagnosis and disease severity assessment ...

Improvement of the Aerodynamic Performance of a Darrieus Vertical-Axis Wind Turbine Using a Passive Deflector in Urban Environments

Energies
The integration of wind energy into urban environments is constrained by low wind speeds, high turbulence, and the recurrent negative torque experienced by lift-driven vertical-axis wind turbines (VAWTs).

Quantitative MRI Uncovers Subtle Cortical Damage in Myelin Oligodendrocyte Glycoprotein Antibody‐Associated Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether myelin‐sensitive quantitative MRI reveals microstructural abnormalities in normal‐appearing cortex (NACtx) in myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), indicating that conventional MRI underestimates remission residual cortical injury.
