Rank-Dependent Measures of Bi-Polarization and Marginal Tax Reforms [PDF]

In this paper, we investigate a dual class of bi-polarization indices, namely rank-dependent bi-polarization indices. We show that these indices may be characterized with the generalized positional transfer sensitivity property.

Molecularly Engineered Nitrate Double Perovskites with Elevated Ferroelectric Phase Transition Temperature and Large Piezoelectric Response

Advanced Science, EarlyView.
This study reports molecularly engineered nitrate double perovskites based on systematic BI‐site cation substitution. This molecular engineering modulates local BI···NO3 interactions, nitrate connectivity, and collective physical responses, accompanied by structural conversion from mixed corner‐/face‐sharing structures to three‐dimensional corner ...

Adaptive Active Illumination Via Translationally and Axially Tunable Cascaded Metasurfaces

Advanced Science, EarlyView.
Active three‐dimensional sensing faces a fundamental trade‐off between seeing farther and covering more of the scene. Translationally and axially tunable cascaded metasurfaces overcome this limitation by continuously adapting beam direction and illumination coverage.
