Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides
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 ...

On the numerical performance of a domain decomposition method for conformal mapping
This paper is a sequel to a recent paper [14], concerning a domain decomposition method (hereafter referred to as DDM ) for the conformal mapping of a certain class of quadrilaterals.

Ferroelectric domain variants that are energetically equivalent are expected to remain preserved during polarization reversal. However, phase‐field simulations reveal that inclined domain walls in relaxor ferroelectrics can undergo irreversible elimination during alternating current poling through a proximity effect driven by long‐range elastic ...

SYNTHESIS OF CERTAIN MECHANISMS WHICH GENERATE LUNULES OVER POLYGONS WITH 5 SIDES [PDF]
A synthesis for a mechanism relying on a sequence of articulated quadrilaterals which plot lunules along a penthagon is made. The plotting is successful. The speeds of plotting points are neither equal, nor constant.

The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

A quadrilateral is said to be rational if its four sides, the two diagonals and the area are all expressible by rational numbers. The problem of constructing rational quadrilaterals dates back to the seventh century when Brahmagupta gave an elegant solution of the problem. In 1848 Kummer gave a method of generating all rational quadrilaterals.
