A Day in Linguistic History [PDF]

open access: yes, 1976
The day begins like any other day. A few students straggle toward the Union in search of coffee and eggs. Delivery trucks come on the campus. At the entrance, the sign still reads SUSAN DOE UNIVERSITY FOUNDED 1894 NO SOLICITORS.

Coexisting Rashba/Dresselhaus Spin Splitting in Solution‐Processed Bournonite Films Using Circular Photogalvanic Effect

open access: yesAdvanced Functional Materials, EarlyView.
Circular photogalvanic effect measurements and first‐principles calculations reveal spin‐splitting states in solution‐processed bournonite films (CuPbSbS3) due to structural and bulk inversion asymmetry. The results provide experimental confirmation of coexisting Rashba and Dresselhaus spin‐splitting states in this non‐centrosymmetric chalcogenide ...

The Effect of Purcell Cavities on the Lifetime of Thermally Activated Delayed Fluorescent Emitters

open access: yesAdvanced Functional Materials, EarlyView.
A pressing challenge to OLED displays and lighting is to balance high efficiency and long operational lifetime in the deep blue spectrum. The Purcell effect can reduce the triplet density and hence the probability for destructive energy‐driven triplet annihilation events that limit the OLED lifetime. Here we study of the Purcell effect on two different

TGNap1 is required for microtubule-dependent homeostasis of a subpopulation of the plant trans-Golgi network

open access: yesNature Communications, 2018
The plant trans-Golgi network comprises functionally distinct subcompartments. Here Renna et al. show that the TGNap1 protein acts in microtubule-dependent biogenesis, tracking and function of a TGN subset, highlighting diversification within the plant ...
