Robust CDF‐Filtering of a Location Parameter

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT This paper introduces a novel framework for designing robust filters associated with signal plus noise models having symmetric observation density. The filters are obtained by a recursion where the innovation term is a transform of the cumulative distribution function of the residuals.

A sinc approximation for the indefinite integral

open access: yes, 1983
A method for computing ∫ 0 x f ( t ) d t , x = ( 0 , 1 ) \smallint _0^xf(t)\;dt,x = (0,1) is outlined,

Perceptual Priors Update Contextual Feedback Processing in V1

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Contextual information and prior knowledge facilitate perceptual processing, improving our recognition of even distorted or obstructed visual inputs. As a result, neuronal processing elicited by identical sensory inputs varies depending on the context in which we encounter those inputs.

Double exponential transformation in the Sinc-collocation method for two-point boundary value problems

open access: yes, 2002
In 1974, Takahasi and Mori proposed the double exponential transformation for efficient evaluation of integrals of an analytic function with end point singularity.

FUNCTIONAL TRANSPOSITION OF ‘SINCE’ IN THE ENGLISH LANGUAGE

open access: yesAnnals of the University of Craiova. Series Philology. Linguistics
The paper is aimed at tracing the evolution of the preposition, adverb, and conjunction SINCE as the initial and transposed categories. The research proves that the adverb SINCE was formed due to grammaticalization of the construction SIÐ ÐAN/SIÞ ÞAN in 850-950 and has undergone functional transposition into the conjunction and the preposition.

Distinctive neurophysiological correlates of sound onset and offset perception in humans

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Electroencephalography (EEG) recordings were obtained from participants listening to successive pairs of 1‐2 s noises in a silent background (Study 1) or successive pairs 1‐2 s silent gaps in a noise background (Study 2). Participants heard the same stimuli in the context of either a duration discrimination task (identifying ...

Quantitative Diffusion and T2 Mapping Using RF‐Modulated Phase‐Based Gradient Echo Imaging

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 49-65, July 2026.
ABSTRACT Purpose To introduce and evaluate the feasibility of a novel RF‐phase modulated gradient echo (GRE) method for quantitative diffusion MRI, aimed at mitigating geometric distortion and enabling high‐resolution 3D quantitative diffusion/T2 mapping as a complementary alternative to conventional DWI.

The Best Approximation of the Sinc Function by a Polynomial of Degree with the Square Norm

open access: yesJournal of Inequalities and Applications, 2010
The polynomial of degree n which is the best approximation of the sinc function on the interval (0, ] with the square norm is considered. By using Lagrange's method of multipliers, we construct the polynomial explicitly.

Chemical Shift Separated and Compensated Ultra‐Short Echo‐Time Imaging

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 121-133, July 2026.
ABSTRACT Purpose To develop a modified binomial excitation scheme for ultra‐short echo‐time (UTE) imaging that allows for the separation of water and fat signals and the correction of chemical shift artifacts. Methods Theoretical derivation and numerical Bloch simulations were performed for a modified water‐excitation binomial pulse scheme to calculate

Scattering from the pec flat strip by using the method of moments with sinc type basis functions

open access: yes, 2006
Using sinc methods is a very powerful technique in physics and mathematics. They give good accuracies and they're easily implemented. Method of Moments (MoM) is used to transform linear operator equations to linear algebraic equations such as matrix ...
