An Exploratory Analysis of Early Care Differences and Risk of Post-Maxillary Advancement VPI in Individuals With Cleft Palate.

Objective: To investigate whether differences in early cleft care increase risk of velopharyngeal insufficiency (VPI) after maxillary advancement.

Design: Retrospective cohort study.

Setting: Large pediatric tertiary care hospital.

Anisotropic Ferroelectricity in Polar Vortices.

The exotic polarization configurations of topologically protected dipolar textures have opened new avenues for realizing novel phenomena absent in traditional ferroelectric systems. While multiple recent studies have revealed a diverse array of emergent properties in such polar topologies, the details of their atomic and mesoscale structures remain incomplete. Through atomic- and meso-scale imaging techniques, the emergence of a macroscopic ferroelectric polarization along both principal axes of the vortex lattice while performing phase-field modeling to probe the atomic scale origins of these distinct polarization components is demonstrated.
