The equality problem for infinite words generated by primitive morphisms [PDF]

open access: yesarXiv, 2009
We study the equality problem for infinite words obtained by iterating morphisms. In particular, we give a practical algorithm to decide whether or not two words generated by primitive morphisms are equal.

Subsurface Oxygen Vacancy Mediated Surface Reconstruction and Depolarization of Ferroelectric BaTiO3 (001) Surface

open access: yesAdvanced Science, EarlyView.
In‐situ atomic‐scale electron microscopy reveals that vacuum‐annealed ferroelectric BaTiO3 (001) surfaces exhibit BaO termination with periodic Ba deficiency and TiOx adunits. Planar oxygen vacancy accumulation in the subsurface TiO2 layer mitigates the depolarization field, facilitating cooperative rumpling of surface and subsurface layers in a tail ...

Cryo‐EM Analysis of a Tri‐Heme Cytochrome‐Associated RC‐LH1 Complex from the Marine Photoheterotrophic Bacterium Dinoroseobacter Shibae

open access: yesAdvanced Science, EarlyView.
Cryo‐EM reveals a closed 17‐subunit LH ring encircling the RC‐LH1 complex in Dinoroseobacter shibae, featuring a novel helix‐turn‐helix subunit bridging RC and LH. Mg2⁺/Ca2⁺ stabilizes the complex, while periplasmic Cyt c₂ mediates electron transfer via a tri‐heme Cyt to the special pair of bacteriochlorophylls. Insights into energy/electron efficiency
