For uncorrelated noise the SNR increases by N1/2 with N the number of repetitions and 5000 repetitions result in a detection limit of ~45 fT. This is clearly sufficient to detect the N20m with an amplitude of 0.5 pT.
A picture caption in Science Times on Tuesday with an article about dogs trained to detect lung cancer by sniffing patients' breath misstated the breed of a dog, shown in the picture, that achieved high marks in a detection experiment.
Among these are interior cameras, heat sensors and motion detectors that are intended for other uses, but could possibly play a role in a detection device.

Should this transaction take place, we believe that it would be an attractive step, securing clear global leadership for Smiths in a detection market seeing a resumption of growth, and in which Smiths appears to have resolved its own performance issues.
As important in a detection dog's work is not only that he knows about specific odors, but that he does not know what humans know: the nature of a traffic stop, and what a driver's moustache, or music, or sports jacket might tell a police officer about his likelihood for being a suspicious character.
In the first place, there is a distinction between sustaining attention in a detection task, where the overall workload is high, and sustaining it when little is happening except for the occasional looked-for events.

Finally, in a detection experiment there will always be some 'lucky guesses' that are correct.
They implement the model in a detection framework based on correlation signatures, profiles, and security policies.
