Linear Algebra and its Applications, 2000 Recently a definition of Hankel determinants \(H^n_k\) with entries in a finite-dimensional real vector space was given in terms of designants and Clifford algebra. Sylvester's identity can still be used for computing these determinants recursively, but the aim of this paper is to present a more efficient method avoiding the use of the Clifford algebra

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.

COEFFICIENT INEQUALITY FOR MULTIVALENT BOUNDED TURNING FUNCTIONS OF ORDER α
Проблемы анализа, 2016 The objective of this paper is to obtain the sharp upper bound to the H_2(p + 1), second Hankel determinant for p-valent (multivalent) analytic bounded turning functions (also called functions whose derivatives have positive real parts) of order α (0 ≤ α

Estimates for Analytic Functions Connected with Hankel Determinant
Ukrainian Mathematical Journal, 2021 UDC 517.5 We give an upper bound of Hankel determinant of the first order for the classes of an analytic function. In addition, an evaluation with the Hankel determinant from below will be given for the second angular derivative of analytic function. For new inequalities, the results of Jack's lemma and Hankel determinant were used.

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.Ultrafast pump‐probe spectroscopy of two evolutionarily divergent blue copper proteins reveals distinct low‐frequency ground‐state collective modes (38 cm−1 in SLAC, 29 cm−1 in azurin) generated via impulsive stimulated Raman scattering, potentially reflecting the differences in the rigidity of the surrounding protein scaffold beyond a conserved Cu ...

Photonics of Topological Magnetic Textures
Advanced Optical Materials, Volume 14, Issue 13, 3 April 2026.Localized noncollinear magetic textures imprint their geometry and topology onto traversing photonic fields endowing them with orbital angular‐momentum, chirality, and magnetoelectric densities. Abstract Topological textures in magnetically ordered materials are an important case studies for fundamental research with promising applications in data ...

Hankel determinant solution for elliptic sequence
Linear Algebra and its Applications, 2015 We show that the Hankel determinants of a generalized Catalan sequence satisfy the equations of the elliptic sequence. As a consequence, the coordinates of the multiples of an arbitrary point on the elliptic curve are expressed by the Hankel determinants.

Identifying Out‐of‐Voxel Echoes in Edited MRS With Phase Cycle Inversion
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 1921-1933, April 2026.ABSTRACT Purpose To identify the origin of out‐of‐voxel (OOV) signals based on the coherence transfer pathway (CTP) formalism using signal phase conferred by the acquisition phase cycling scheme. Knowing the CTP driving OOV artifacts enables optimization of crusher gradients to improve their suppression.
