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.

Analytical Expressions for the Depth Investigation Characteristic and Mean Sensitivity Depth for Electrical Resistivity Surveys Using Long Electrodes

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT In analyses of the electrical resistivity method, it is usually assumed that electrodes can be represented as point current sources and point potential measurements. However, if electrodes extend into the ground to depths that are similar to their spacing or greater, this approximation may not be valid.

Transient Absorption Spectroscopy of Blue Copper Sites in Divergent Protein Folds: Azurin Versus Multicopper Oxidase

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 ...

A polynomial approach to Hankel norm and balanced approximations

Linear Algebra and its Applications, 1991
The theory of Hankel norm approximations was developed, in great generality, in a series of papers published by Adamjan, Arov and Krein between 1968 and 1978. The aim of the paper under review is to present a new approach to problems of Hankel norm and balanced approximation.

A Grassmanian approach to the Hankel norm approximation problem

, 2004
This paper concerns the unifying framework to strictly contractive extension problems, which is usually referred to as the band method. The solution to the so-called strictly contractive extension problem in this abstract framework, when applied to a certain concrete case, yields a complete characterization of solutions to the sub-optimal Nehari ...
