Here we report cryo-EM structures of the full-length Tetrahymena ribozyme in substrate-free and bound states at a resolution of 3.1 Å. Newly resolved peripheral regions form two coaxially stacked helices; these are interconnected by two kissing loop pseudoknots that wrap around the catalytic core...

With this method, EPS of the pixel at different wavelengths can be adjusted accordingly to the orthogonal polarization control requirement. To demonstrate this method, we start with the general form of Jones matrix for an elliptic cylinder metaatom given by26 $$J(\lambda ) = R\left( { - \...
Jin-Gui-Shen-Qi Wan (JGSQ) has been used in China for thousands of years to treat various ailments, including frequent urination, blurred vision, and soreness in the waist and knees. It has traditional therapeutic advantages in improving eye diseases. Cl

In general, amine-initiated polyesters with diverse microstructures make it easier to form various amine-ester complexes to induce red-to-NIR CL, suggesting the unique microstructures of polymer chains relative to small molecules in manipulating the photophysical properties (Fig. 5)40,41. Fig. 5:...
