Relationships among transforms, convolutions, and first variations [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
In this paper, we establish several interesting relationships involving the Fourier-Feynman transform, the convolution product, and the first variation for functionals F on Wiener space of the form F(x)=f(〈α1,x〉,…,〈αn,x〉),

A first genetic portrait of synaptonemal complex variation.

open access: yesPLoS Genetics, 2019
The synaptonemal complex (SC) is a proteinaceous scaffold required for synapsis and recombination between homologous chromosomes during meiosis. Although the SC has been linked to differences in genome-wide crossover rates, the genetic basis of standing ...

A Modified Generalized Analytic Feynman Integral Associated with the Bounded Linear Operator

open access: yesAxioms, 2022
In this paper, we define a modified and generalized analytic Feynman integral associated with the bounded linear operator on abstract Wiener spaces. We then prove its existence. We also establish some modified and generalized analytic Feynman integration

Basic Fundamental Formulas for Wiener Transforms Associated with a Pair of Operators on Hilbert Space

open access: yesMathematics, 2021
Segal introduce the Fourier–Wiener transform for the class of polynomial cylinder functions on Hilbert space, and Hida then develop this concept. Negrin define the extended Wiener transform with Hayker et al. In recent papers, Hayker et al. establish the

Next generation of neurological therapeutics: Native and bioengineered extracellular vesicles derived from stem cells

open access: yesAsian Journal of Pharmaceutical Sciences, 2022
Extracellular vesicles (EVs)-based cell-free therapy, particularly stem cell-derived extracellular vesicles (SC-EVs), offers new insights into treating a series of neurological disorders and becomes a promising candidate for alternative stem cell ...

Heart rate variation and human body burdens of environmental mixtures in the Cree First Nation communities of Eeyou Istchee, Canada

open access: yesEnvironment International, 2021
Introduction: Heart rate variability (HRV) is a measure of cardiac autonomic regulation that examines the variation in beat-to-beat fluctuations in heart rate.

Feynman Integral and a Change of Scale Formula about the First Variation and a Fourier–Stieltjes Transform

open access: yesMathematics, 2020
We prove that the Wiener integral, the analytic Wiener integral and the analytic Feynman integral of the first variation of F(x)=exp{∫0Tθ(t,x(t))dt} successfully exist under the certain condition, where θ(t,u)=∫Rexp{iuv}dσt(v) is a Fourier–Stieltjes ...

Total Variation Projection With First Order Schemes [PDF]

open access: yesIEEE Transactions on Image Processing, 2009
This article proposes a new algorithm to compute the projection on the set of images whose total variation is bounded by a constant. The projection is computed through a dual formulation that is solved by first order non-smooth optimization methods. This yields an iterative algorithm that applies iterative soft thresholding to the dual vector field ...

Active Methodologies for Teaching Grammar: the Roulette of Social Relations of “nós” and “a gente”

open access: yesSignum: Estudos da Linguagem, 2020
In this paper, we expose the relevance of active methodologies for teaching grammar through the application of the game “The roulette of social relations of ‘nós’ and ‘a gente’” in a 9th grade class at Jacintho de Figueiredo School (Aracaju/SE) to ...
