he found that, although most of them went straight through, some rebounded back in the direction from which they came. (b) From this experiment, he concluded that the atom must be constructed like a miniature solar system, with the positive...

The whale optimization algorithm has received much attention since its introduction due to its outstanding performance. However, like other algorithms, the whale optimization algorithm still suffers from some classical problems. To address the issues of

How to observe a coherent superposition of an atom and a molecule We demonstrate that it is possible, in principle, to perform a Ramsey-type interference experiment to exhibit a coherent superposition of a single atom and... MR Dowling,SD Bartlett,T Rudolph,... - 《Physical Review A》 被...
As a rigorous blind test of both our accuracy prediction and refinement methods, we entered them in the CASP14 structure prediction experiment, and while this manuscript was in the final stages of revision, the independent assessors’ results were presented at the CASP14 meeting. Our methods pe...
All structures within our dataset exhibited a tetrahedral coordination around the metal ion, with the His binding through the Nδ atom. The preference of Nδ over Nε histidine coordination is highly frequent among Zn-fingers, but the functional and structural significance of these two diverse ...
