Feb 20, 2021 · The nation state is a state that self-identifies as deriving its political legitimacy from serving as a sovereign entity for a nation as a sovereign territorial unit. The term nation state implies that the two geographically coincide. In classical thought, the state was identified with political society and civil society as a form of political ...
The presence of this additional density is distinguishable only in the omit map and in the 2mF obs − DF calc map at high resolution, and not in the earlier 2.25 Å resolution map 8 (Extended Data Fig. 5). We refined the 2F data against two partial-occupancy models at the catalytic site based on the S-state populations (see Methods).

May 3, 2023 · The reaction takes place in photos ystem II, where the Mn CaO cluster rst. stores four oxidizing equivalents, the S to S intermediate states in the Kok cycle, sequentially generated by ...
May 3, 2023 · mF obs − DF calc electron density map near the OEC region in the 3F(500 µs) time point. The map is shown at a contour level of 2.5σ (in yellow). Electron density is observed at this level in-between W3 and W4 (see red arrow), possibly indicating a transient water motion that was also corroborated by the overlap of the omit map densities.

May 3, 2023 · Main. Serial femtosecond X-ray crystallography at X-ray free electron lasers (XFELs) 7 enabled us to collect crystallography data of photosystem II (PS II) in real time as the reaction progresses at physiological temperature. The four photon-induced water-oxidation reaction in PS II (Fig. 1a,b) was initiated with multiple visible laser flashes.
