They used Earth-based telescopes to detect gaps in the spectrum of infrared light coming from Mars.
A system like this could also detect gaps in cell-tower coverage, weak radio and television signals and sources of radio frequency interference.
However, these are also opportunities to detect gaps, uncover areas that have been less explored, and devise a research agenda for future work.
Mapping approaches are reliant on the capacity to detect gaps in, or fragmentation of, the forest canopy to identify degradation activity [4].
The ultimate goal is to understand what has worked in terms of housing and transport and to detect gaps in knowledge to promote avenues for future research for a more sustainable urbanization process.
The first approach encompasses methods that characterise the type of degradation and track disturbance, detect gaps in, and fragmentation of, the forest canopy, and proxies that provide evidence of forestry activity.
Our framework can be used to detect gaps in available data, translate indicator systems into practical conservation, identify combined sets of indicators to monitor biodiversity in target habitats, and recognize most suitable surrogates when information for some indicators is missing.
Thus we showed a biological marker indicating that the temporal acoustical features constituting the gap stimulus were represented at thalamocortical level even in the oldest participants and for the most difficult to detect gaps.
Indeed, older listeners are able to detect gaps as short as young listeners when the separation between the onset of the sound and the onset of the gap is sufficiently large [14], [17].
This is an important step if one aims to detect gaps among a concept list established a priori.
These findings show that tinnitus in humans has no effect on the ability to detect gaps in auditory stimuli.
