The phrase "axis cannot be" is correct and usable in written English.
It can be used in contexts discussing limitations or impossibilities related to an axis in various fields such as mathematics, physics, or design.
Example: "In this model, the axis cannot be adjusted beyond a certain point without compromising stability."
Alternatives: "axis is not allowed to be" or "axis must not be".
Therefore, the difference in the work required to unfold 10FNIII by pulling along either axis cannot be explained by mere reorientation of 10FNIII.
In such 2D methods, spines above and below the dendrite projecting along the optic axis cannot be detected reliably, and spine shapes, lengths and other measurements are necessarily distorted by the absence of information in the Z direction.
Indeed, in contrast to M3 and M4, the residues in M1 and M2 are homogeneously conserved (as noted in the Figure 2a of ref. [11]) so that the orientation around their principal axis cannot be determined reliably on the basis of conservation alone.
Experiments revealed that the axis cannot be properly reoriented as soon as the frequency has changed in phase II.
The implications of our findings are limited because the dose distribution in the lateral axis cannot be modified using the current technique.
The possibility of other iron-regulatory molecules such as lipocalin 2 [32] impinging on the hepcidin-Fpn axis cannot be ruled out.
For this class the projection of the oscillations on the x-axis cannot be separated by that of the silent state (B).
Because we could not observe antitumor effects in vivo after downregulation of the hypothalamic-ovarian axis by using the GnRH-I agonist triptorelin, the downregulation of the hypothalamic-ovarian axis alone cannot be responsible for the antitumor effects of GnRH-II antagonists.
However, the usual techniques are suitable only for rays in systems with a common straight-line optical axis, and cannot be used in systems containing mirrors and/or prisms.
Hence the asymmetry in horizontal-vertical axis bias cannot be attributed to perceptual stabilization due to interrupted viewing.
Although the front rear axis of each cell tends to be aligned sequentially from the front through the process in which cells move to the open space, the sequential axis alignments cannot be transmitted correctly in the case of weak intercellular adhesion because of the agitation by biological fluctuations.
