Python does this in constant time without having to scan through every item by using hash functions. When Python looks up a key foo in a dict, it first computes hash(foo) (which runs in constant-time). Since in

What does it mean when DBCC LOGINFO returns many rows with status = 2 and DBCC OPENTRAN returns no active open transactions? What does ms/s mean? What does RTM stand for? What does string "OBJECT: 7:1797581442:0" in deadlock log mean? What does Suspended in Activity monitor mean What...
The coordinates have to be changed to put the text where the user wants. 96 points is what I use for images, obviously those values (and things like the font) are determined by the user. Just because you don't understand it doesn't mean its not a ...
In Poincaré, given a closed curve, the boundary does not wrap around it, so naively we would seem to be missing the intervals/geodesics that would be tangent to the portion of the curve that is farther away from the boundary. As explained above and seen in Fig. 1, this is allowed ...
1.1 Introduction Demography is a science that connects individual processes and events to the development of cohorts and then to the dynamics of populations. It does so with mathematical models that distinguish among individuals based on their character- istics.1 The most familiar such model is the...
To illustrate, the symmetric thiourea group of IT1t is solved in the crystal structure in a tautomeric state in which the nitrogen N4 forms a salt bridge with Asp972.63 (Wu et al., 2010). However, the electron density does not exclude the existence of a very similar conformation with the...

Virtual columns provide flexibility and space savings for the table, and more importantly, adding/dropping such columns does not require a table rebuild. These behaviors make it a much better choice for storing and processing non-relational data such as JSON. However, since the columns themselves ...
