The phrase "alternative signal" is correct and usable in written English.
It can be used in contexts where you are referring to a different or substitute signal, such as in communication, technology, or data transmission.
Example: "In case of interference, we should switch to an alternative signal to maintain the connection."
Alternatives: "substitute signal" or "replacement signal".
This assumes that the only true phylogenetic signal is ancestry and that functional, structural, and other factors will not add an alternative signal.
In this review, we indicate examples of alternative signal pathways for recent anticancer drugs, and the use of original, Python-based software to systematically identify signaling pathways that could facilitate resistance to drugs targeting a particular protein.
Several sigma factors are present (SigB, SigI, SigW) and may act as part of alternative signal transduction for specific genes or regulons under both cold and osmotic stress response as has been observed in other Bacillus spp. and other gram-positive species (Budde et al., 2006; Hecker et al., 2007; Hahne et al., 2010).
A current density is specified as a function of time: a direct current (DC) during the time needed to system to achieve a steady state, then as an alternative signal of a given frequency imposed on the DC bias applied from the beginning.
As an alternative, signal amplification by reversible exchange (SABRE) of parahydrogen on transition metal catalysts can hyperpolarize a variety of substrates, but to date this scheme has required transfer of the sample to low magnetic field or very strong RF irradiation.
Alternative signal processing methods for CFO compensation in the frequency domain should be developed.
These pathways are known to be regulated downstream of MAPK and could act as alternative signaling pathways to the classical canonical Ras/MAPK/MEK1/2 activation in T cells.
Fong, J. T. et al. Alternative signaling pathways as potential therapeutic targets for overcoming EGFR and c-Met inhibitor resistance in non-small cell lung cancer.
The on-going strategies to block only one of the above signaling effectors result cancer cells to overcome such inactivation using alternative signaling pathways.
They manage the customer acquisition and retention, develop systems to assess credit based on alternative signals and, over time, build up a customer profile that reduces credit risk.
If a scenario plays out where alternative signals begin to rival traditional degrees, this won't necessarily be a bad thing for universities.
