. To include the output from one command within the command line for another command, enclose the command whose output is to be included within ` backquotes ` . For example: echo The date today is `date +%d/%m/%y` The date today is 17/05/95 . The output from the command date +%d/%m/%y is substituted at the appropriate location within a command line that uses the echo command.

Underdetermined sets is a new type of data structures (terms) developed in Actor Prolog . ... The point is that an underdetermined set can include some indefinite rest (a tail) like a list in usual Prolog . At the same time, the order of elements of an underdetermined set can be arbitrary one and it does not affect results of unification of underdetermined sets. Moreover, Actor Prolog guarantees that a rest of an underdetermined set never contains elements that are explicitly given in the set. ...

. The black hole at the center of the NGC 4051 galaxy emits a hot wind of chemical elements, including elements like carbon and oxygen that are critical for life. The hot wind originates very close to the black hole, at a distance about five times the size of Neptune's orbit. Although speedy, the wind is weaker than expected and ejects only 2 to 5 percent of accreting material. George Seitz/Adam Block/NOAO/AURA/NSF
