Competition and Coexistence of Screening Mechanisms in Ferroelectric Thin Films and Superlattices
We present a theoretical and computational study of mechanisms that screen the depolarising field in ferroelectric materials, namely domains and two-dimensional electron gases. A more realistic electrostatic description of thin films, which accounts for the presence of a substrate has been derived. …

Competing polar and nonpolar distortions and phase transitions in low-dimensional materials
Knowledge of different phases and phase transitions in low-dimensional systems is essential for the understanding and control of nanoscale devices. Theoretical models aided by first-principles calculations have proven invaluable in this respect. However, observed behaviour often differs from what …

PATTERNS OF AMERICAN BUMBLE BEE (BOMBUS PENSYLVANICUS) ABUNDANCE ACROSS RESTORED HABITATS IN EAST TEXAS ECOSYSTEMS
<p>Many bumble bee species (<em>Bombus</em> spp.), are declining, yet drivers of their abundance remain partially understood. In the southeastern United States, historically open habitats have shifted towards closed-canopy conditions via fire suppression, deforestation and afforestation, altering …
