Finally, just outside the entrance to the exhibition you are reminded of the greatness and longevity of Chinese ceramics by an imposing display of large Neolithic earthenware jars, one of the signal points of origin of the world's ceramic arts.
Thirty-eight years ago, in Ridley Scott's "Alien," we met the crew of the Nostromo, a spaceship that, having picked up a signal of mysterious origin, was diverted to an uncharted planet.
It may take decades after the initial indications of alien life for scientists to gather enough evidence to be certain or to decipher a signal of artificial origin.
If it is evident that first name and surname provide a relevant signal of national origin to the recruiter, it is also possible that they provide a signal of religious closeness.
Here we employ optical trapping techniques to investigate the structure of a −1 programmed ribosomal frameshift (−1 PRF) sequence element located in the CCR5 mRNA, which encodes a coreceptor for HIV-1 and is, to our knowledge, the first known human −1 PRF signal of nonviral origin.
No small feat, but surely finding a signal of intelligent origin from another planet would be a momentous and impactful find for them — assuming they don't already know about us from past visits!
An electrical signal of unknown origin caused the explosion to go off 0.25 seconds early, ruining experiments that required split-second timing.
There was a highly significant and strong main effect of habitat but no main effect of lake, indicating only a weak historical signal of lake origin (Table 1).
The isotopic ratio of the heavy element strontium (87Sr/86Sr) is one marker hypothesized to serve as a useful signal of geographic origin [6], [8], [27], [28].
The blank benzene-d6 sample showed strong signals from a trace amount of benzene at 7.16 ppm and from water at 0.39 ppm, a modest signal of unknown origin at 4.66 ppm (possibly methanol), and a few minor signals between 1 and 3.5 ppm.
