Of course, not everyone wants to track every second of their day or exercise routine, is wearing a Fuel Band (or some alternative thereof) or is an avid runner.
Despite the speculative nature of real estate E.T.F.'s, not all market watchers are ready to dismiss them, especially when they consider the investment alternatives — or lack thereof.
DF-1 cells (and derivatives thereof) constitute viable alternatives, for the manufacture of MVA-based vaccines, to primary CEFs – the conventional cell substrate for MVA vaccines that is not amenable to genetic complementation strategies due to these cells' finite lifespan in culture.
Importantly, DF-1 cells (and derivatives thereof) are attractive alternatives to primary CEFs for large-scale production of MVA-based vaccines because of their origin through spontaneous immortalization, rather than oncogenic transformation, of embryonic fibroblasts derived from chickens that were free from endogenous retroviruses [40], [41].
Not one addressed the issue of choice, or lack thereof.
We propose herein that the true techno-economic advantage (or lack thereof) of choosing alternative TES systems should be judged by a 'normalized cost of thermal energy storage (NCOTES)' which normalizes the cost of storage systems with regards to their annual electricity generation capacity.
Rare cases of successful saltation in nature represent displacement of a taxon on the adaptive landscape to an alternative fitness "peak" or slope thereof.
Isoforms are produced by alternative splicing, alternative promoter or codon initiation usage, or combinations thereof [ 7].
Oftentimes, the paraphrase will involve a different style of quantification, whether an alternative to classical quantification or an extension thereof.
A saltational event allowed a bumble bee mimic to cross the fitness "valley" and reach an alternative fitness "peak" or at least slope thereof [20], [21].
