1,645,287 | In general, the most accurate predictions are for loops of fewer than 8 amino acids. Extremely short loops of three residues can be determined from geometry alone, provided that the bond lengths and bond angles are specified. Slightly longer loops are often determined from a "spare parts" approach, in which loops of si... | https://en.wikipedia.org/wiki?curid=8865843 | 1,644,359 |

1,002,707 | "Svabhāva"'s cognitive aspect is merely a superimposition ("samāropa") that beings make when they perceive and conceive of things. In this sense then, emptiness does not exist as some kind of primordial reality, but it is simply a corrective to a mistaken conception of how things exist.

1,099,997 | There are many important implications from the fluctuation theorem. One is that small machines (such as nanomachines or even mitochondria in a cell) will spend part of their time actually running in "reverse". What we mean by "reverse" is that it is possible to observe that these small molecular machines are able to ge... | https://en.wikipedia.org/wiki?curid=333170 | 1,099,437 |
