Alternatives: "a theoretical link" or "an imagined relationship."
This observation makes a somewhat hypothetical connection to a concept presented 150 years ago by Rudolf Virchow [42] and Julius Conheim [43], who proposed the "embryonic rest hypothesis of cancer development" [44].
Theoretical physicists have forged a connection between the concept of entanglement itself a mysterious quantum mechanical connection between two widely separated particles and that of a wormhole a hypothetical connection between black holes that serves as a shortcut through space.
Until now, however, central hemodynamic parameters and autonomic activity have not been studied concurrently in HBO₂, so any hypothetical connections between the two have remained untested.

We also demonstrated how the model finds hypothetical connections between experiments, by selecting an experiment of epithelial tissue in non-smokers versus current smokers as being highly relevant to cancer experiments, which naturally makes sense a posteriori.
Although these analyses are far from perfect in terms of predictive ability, they remain the only tools available for predicting miRNA targets, and the output of these analyses is useful for predicting hypothetical connections between miRNAs, targeted pathways, and biological functions.
Based on the genes involved in the light signaling cascade and their impact on metabolic output pathways in several fungi, hypothetical connections between these pathways and light signaling can be drawn, which may be worth exploring in the future.
