In vivo disentanglement of diffusion frequency‐dependence, tensor shape, and relaxation using multidimensional MRI

open access: yesHuman Brain Mapping, Volume 45, Issue 7, May 2024.
Multidimensional MRI combines free gradient waveforms and relaxation encoding for microstructural specificity in complex tissues. We confirm feasibility and robustness of a sparse 2 mm3 whole‐brain in vivo protocol using phantom and healthy individuals, while testing tailored denoising strategies.

Performance Analysis of Two Different Types of Waiting Queues with Working Vacations

open access: yesJournal of Mathematics, Volume 2024, Issue 1, 2024.
This work examines a new class of working vacation queueing models that contain regular (original) and retrial waiting queues. Upon arrival, a customer either starts their service instantly if the server is available, or they join the regular queue if the server is occupied. When it is empty, the server departs the system to take a working vacation (WV)

BICOMPLEX VERSION OF STIELTJES TRANSFORM AND APPLICATIONS

open access: yes, 2020
. Motivated by the recent developments of the integral transform in bicomplex form, in this paper we derive the formula for bicomplex version of Stieltjes transform, it's inverse and relationship with bicomplex Laplace transform.

Laplace Transform in Commutative Banach Algebras [PDF]

open access: yes, 1952
After a brief review of the general theory of commutative complex Banach algebras in Section I, Section II introduces and discusses some important facts about the generalized Laplace-Stieltjes integral.

Measuring the error of dynamic hedging: a Laplace transform approach [PDF]

open access: yes
We compute the expected value and the variance of the discretization error of delta hedging and of other strategies in the presence of proportional transaction costs.

Approximation of the Stieltjes Integral and Applications in Numerical Integration

open access: yes, 2003
Some inequalities for the Stieltjes integral and applications in numerical integration are given. The Stieltjes integral is approximated by the product of the divided difference of the integrator and the Lebesgue integral of the integrand.

A Comparative View of Becker, Lomnitz, and Lambert Linear Viscoelastic Models

open access: yesMathematics
We compare the classical viscoelastic models due to Becker and Lomnitz with respect to a recent viscoelastic model based on the Lambert W function. We take advantage of this comparison to derive new analytical expressions for the relaxation spectrum in ...

Distributions of Functionals of the two Parameter Poisson-Dirichlet Process [PDF]

open access: yes
The present paper provides exact expressions for the probability distribution of linear functionals of the two–parameter Poisson–Dirichlet process. Distributional results that follow from the application of an inversion formula for a (generalized) Cauchy–

Generalization of the effective Wiener-Ikehara theorem [PDF]

open access: yes, 2013
International audienceWe consider the classical Wiener–Ikehara Tauberian theorem, with a generalized condition of slow decrease and some additional poles on the boundary of convergence of the Laplace transform.
