Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks

Advanced Materials, Volume 38, Issue 32, 8 June 2026.
ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

Analysis of Azimuthal Variations Using Multi-Aperture Polarimetric Entropy with Circular SAR Images

Remote Sensing, 2018
In conventional synthetic aperture radar (SAR), sensors with a fixed look angle are assumed, and the scattering properties are considered as invariant in the azimuth.

Removal of Spectro-Polarimetric Fringes by 2D Pattern Recognition

, 2012
We present a pattern-recognition based approach to the problem of removal of polarized fringes from spectro-polarimetric data. We demonstrate that 2D Principal Component Analysis can be trained on a given spectro-polarimetric map in order to identify and

Structure‐Guided Surface Engineering of an Artificial Metallolyase for Highly Enantioselective Michael Addition

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
X‐ray visualization of copper‐binding modes revealed nonspecific surface metal sites that compromise stereoselectivity. Structure‐guided mutations suppressed background reactivity and enabled precise enantioselective control in the Michael addition, delivering up to 99% ee.

Polarimetric Scattering Properties of Landslides in Forested Areas and the Dependence on the Local Incidence Angle

Remote Sensing, 2015
This paper addresses the local incidence angle dependence of several polarimetric indices corresponding to landslides in forested areas. Landslide is deeply related to the loss of human lives and their property. Various kinds of remote sensing techniques,

Prospects for multiwavelength polarization observations of GRB afterglows and the case GRB 030329

, 2004
We explore the prospects for simultaneous, broad-band, multiwavelength polarimetric observations of GRB afterglows. We focus on the role of cosmic dust in GRB host galaxies on the observed percentage polarization of afterglows in the optical/near ...
