Although no air traffic system is using such signals at the moment, the Technology Strategy Board of the UK government is now funding an experiment to look at the practicalities of using the BBC's Freeview – a free-to-air digital TV signal – for just such a purpose.
Using such signals is a simple and effective approach to obtaining commands for controlling active prosthetic hands (Nader 1990; for a review see Zecca et al. (2002)), and it is used, for instance, in Otto Bock hands.
If a fire ant is laying a food trail using such signals and meets another worker, the homeward-bound worker may turn to face her, rushing into her before continuing on, or even pausing briefly to shake her, but researchers think this behavior may only serve to enhance the effects of the chemical being used.
Other types of N-terminal sorting signals exist, for example the PTS2 signal targeting proteins to the peroxisome [ 30], but the number of proteins using such signals is much smaller than those using the SP, MTS or CTP signals.
The advantages of using such signals is illustrated through the results obtained from identifying the dynamics of a mechanical wet-clutch system.
We are not aware of other studies using such signalling pathways to inhibit CAF pro-tumorigenic signalling in a similar way and suggest the term 'deCAF' to denote the partial or complete inhibition of pro-tumorigenic signalling from CAFs.
Despite our growing ability to use such signaling signatures, we remain hampered by the fact that signaling signatures may be particular to an individual cell type and thus our platforms may not be portable from cell to cell, necessitating further cell-specific biosensor development.
Whether the plant host is able to detect fungal invertase activity and use such a signal to differentiate antagonistic from mutualistic biotrophic symbionts is a completely speculative, though plausible hypothesis.
The strategy of using such transcription factors to amplify a signal to many target genes is conserved in evolution, and many examples for such regulation are known from yeast to human.
Using such quick signals turned $1,000 into just $849, which is worse than what we could have achieved had we bought and held SPY.
