Multiresolution Approximation Using Shifted Splines [PDF]

open access: yes, 1998
We consider the construction of least squares pyramids using shifted polynomial spline basis functions. We derive the pre and postfilters as a function of the degree n and the shift parameter 1. We show that the underlying projection operator is entirely

Modal spectral Tchebyshev Petrov–Galerkin stratagem for the time-fractional nonlinear Burgers’ equation [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
Herein, we construct an explicit modal numerical solver based on the spec-tral Petrov–Galerkin method via a specific combination of shifted Cheby-shev polynomial basis for handling the nonlinear time-fractional Burger-type partial differential equation ...

Fast computation of shifted Popov forms of polynomial matrices via systems of modular polynomial equations [PDF]

open access: yes, 2016
International audienceWe give a Las Vegas algorithm which computes the shifted Popov form of an $m\times m$ nonsingular polynomial matrix of degree $d$ in expected$\widetilde{\mathcal{O}}(m^\omega d)$ field operations, where $\omega$ is theexponent of ...

Properties of length-apodized phase-shifted lpgs operating at the phase matching turning point [PDF]

open access: yes, 2012
The characteristics of length-apodized phase-shifted fiber optic long period gratings with full and partial nanostructured coatings have been explored theoretically and experimentally.

Evaluation of Digital Technologies for Home‐Based Assessment in People With Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Digital technologies hold promise for transforming healthcare by enhancing personalized treatments and offer valuable opportunities to improve patient care. Here, we evaluated several novel, self‐administered, home‐based, digital endpoints for their association with corresponding conventional standard clinical measures (primary) in ...

Interpolation of Shifted-Lacunary Polynomials [PDF]

open access: yes, 2010
. Given a “black box ” function to evaluate an unknown rational polynomial f ∈ Q[x] at points modulo a prime p, we exhibit algorithms to compute the repre-sentation of the polynomial in the sparsest shifted power basis. That is, we determine the sparsity

CSF Cytokine Network Organization Predicts Progression Independent of Relapse and MRI Activity in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Progression independent of relapse activity is a major determinant of long‐term disability in multiple sclerosis, but its immunopathologic basis remains incompletely understood. We investigated whether relapse‐independent progression in radiologically stable relapsing–remitting multiple sclerosis is associated with distinct ...

Controlled fabrication of tunable delay using compound phase shifted resonators [PDF]

open access: yes, 2010
Fine tuned, narrowband group delay (“slow light”) is obtained using a compound phase shifted grating and superposing resonances.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.
