Residual Water Suppression in MRS Using HLSVD With Automatic Component Selection Strategy
NMR in Biomedicine, Volume 39, Issue 7, July 2026.Residual water signals in magnetic resonance spectroscopy distort baselines and hinder metabolite quantification. We propose an automatic residual water removal method using HLSVD with the metric, termed as residual water to metabolite variance ratio (RWVR), to guide component selection.

An Algebraic Study of Parametric Stokes Phenomena
Studies in Applied Mathematics, Volume 157, Issue 1, July 2026.ABSTRACT We investigate geometric aspects of co‐equational parametric resurgence, by studying physical problems whose formal asymptotic solutions give rise to Borel transforms lying on an algebraic curve. This perspective allows us to elucidate concepts unique to parametric resurgence such as singularity structures, (virtual) turning points, and the ...

INTEGRAL TRANSFORMS WITH THE HOMOTOPY PERTURBATION METHOD AND SOME APPLICATIONS [PDF]
This paper applies He's homotopy perturbation method to compute a large variety of integral transforms. As illustration, the paper gives special attention to the Esscher transform, the Fourier transform, the Hankel transform, the Mellin transform, the ...

Researches in MathematicsIn this paper, we obtain several analogues of the Paley-Wiener theorem for the Hankel transform of order $m+1/2$ with $m\in\mathbb N$ in weighted spaces $L^2((0;1);x^{2m} dx)$.

Optimal Hankel Norm Model Reduction by Truncation of Trajectories [PDF]
We show how optimal Hankel-norm approximations of dynamical systems allow for a straightforward interpretation in terms of system trajectories. It is shown that for discrete time single-input systems optimal reductions are obtained by cutting 'balanced ...

Countable Basis for Free Electromagnetic Fields
Annalen der Physik, Volume 538, Issue 5, May 2026.ABSTRACT Polychromatic electromagnetic fields are expanded as integrals over monochromatic fields, such as plane waves, multipolar fields, or Bessel beams. However, monochromatic fields do not belong to the Hilbert space of free Maxwell fields, since their norms diverge.

An uniform boundedness for Bochner-Riesz operators related with the Hankel transform [PDF]
, 2002 Let Hα be the modified Hankel transform Hα(f,x) = ∫0∞ Jα(xt)/(xt)α f(t)t2α+1dt, defined for suitable functions and extended to some Lp((0, ∞), x2α+1) spaces. Given δ > 0, let Mαδ be the Bochner-Riesz operator for the Hankel transform.

Gelfand-Shilov spaces for the Hankel transform [PDF]
, 1992 We introduce the subspaces Ga, Gβ and Gβa(a, β⩾0) of the Schwartz space S+ defined on the interval (0, + ∞), which are associated with the Hankel transform in the same way as the Gelfand-Shilov spaces Sa, Sβ and Sβa are with the Fourier transform.

A Decade of Airborne Electromagnetic Surveying Lake Menindee (Australia) Under Varying Water Levels
Geophysical Prospecting, Volume 74, Issue 4, May 2026.ABSTRACT Time domain airborne electromagnetic (AEM) surveying is a mature geophysical tool for imaging the Earth's shallow subsurface. It produces images of the electromagnetic conductivity structure of the earth, down to depths of a few hundred metres.

Discontinuities in an axisymmetric generalized thermoelastic problem
International Journal of Mathematics and Mathematical Sciences, 2005 This paper deals with discontinuities analysis in the temperature, displacement, and stress fields of a thick plate whose lower and upper surfaces are traction-free and subjected to a given axisymmetric temperature distribution.
