An invariance property related to the reverse order law
Linear Algebra and its Applications, 2005 Given a complex matrix \(A\), of size \(m \times n\), \(A^{-}\) denotes a generalized inverse of \(A\) and \(A\{1\}\) the set of all generalized inverses of \(A\). The main result of this paper provides two criteria for the invariance of expressions of the type \(KL^{-}M^{-}N\) with respect to the choice of \(L^{-} \in L\{1\}\) and \(M^{-} \in M\{1\}\),

Slight Truncation Changes in Iron Oxide Nanocubes Strongly Affect Their Magnetic Properties
Advanced Functional Materials, EarlyView.Subtle variations in nanoparticle morphology can lead to significant changes in functional properties. An automated shape‐fitting method captures minor differences in corner truncation between iron oxide nanocubes of similar sizes synthesized under identical conditions, revealing pronounced disparities in their magnetic and hyperthermia behavior ...

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies
Advanced Functional Materials, EarlyView.The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Generalizations of the reverse order law with related results
Linear Algebra and its Applications, 1974 AbstractThis paper presents conditions which are necessary and sufficient for (AB>)+ = B+Aω for all normalized generalized inverses Aω of the complex matrix A. Corresponding conditions are stated which are equivalent to the situation where (AB)+ = BωA+ is satisfied by each weak generalized inverse Bω of B. The results are applied to theorems by Baskett

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides
Advanced Functional Materials, EarlyView.A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...
