TL;DR: The X-ray Surveyor (X-S) as discussed by the authors is a large-scale mission with a high-resolution mirror assembly and an instrument set, which may include an x-ray microcalorimeter, a highdefinition imager, and a dispersive grating spectrometer and its readout.
Journal ArticleDOI
First results from a next-generation off-plane X-ray diffraction grating

TL;DR: In this article, a novel grating fabrication method that utilizes common lithographic and microfabrication techniques to produce the high fidelity groove profile necessary to achieve high resolving power grating spectrometers is presented.
Journal ArticleDOI
Probing Domain Functions of Chimeric PDE6α′/PDE5 cGMP-Phosphodiesterase
Alexey E. Granovsky,Michael Natochin,Randall L. McEntaffer,Tamara L. Haik,Sharron H. Francis,Jackie D. Corbin,Nikolai O. Artemyev +6 more
TL;DR: The data suggest that both putative noncatalytic sites of PDE6α′ are important for binding of cGMP, and that the two binding sites are coupled.
Proceedings ArticleDOI
