The phrase "ac alignment" is not correct in standard written English and lacks clarity.
It may be intended to refer to "AC alignment" in a specific technical context, such as electrical engineering or audio equipment, but without context, it is ambiguous.
Example: "The technician performed the AC alignment to ensure optimal performance of the audio system."
Alternatives: "Alternating current alignment" or "AC calibration."
Fusion was stimulated by an AC alignment pulse (8 10 V AC, 10 15 s), followed by a square wave DC pulse (3.3 3.8 kV/cm DC, 10 15 µs), followed by an additional AC pulse to stabilize membrane contact (8 10 V AC, 5 s).
The number of osteolytic areas and their sizes in our 40 patients were not related to loss of postoperative AC alignment, consistent with other reports [34, 35].

A 3D mesh of the head was generated using the mesh functions within Brain Voyager applied to the native space T1 anatomical volume after AC-PC alignment.

For example, Chen and co-workers studied the effect of the frequency of AC bias on the alignment of SWNTs [192].
Alignment of Ac contigs and Masp proteins showed similarity in most positions containing glycine and serine residues, but not in positions with proline residues (Additional file 3).
A sequence alignment of Ac-AChBP with the rat α3, α6, β2, and β4 nAChRs is shown in Fig. 3.
(A) Sequence alignment of Ac-AChBP, rat α3 nAChR, and rat α6 nAChR; regions colored yellow indicate the amino acids that are not conserved between the α3 and α6 ligand binding sites, regions colored blue indicate the amino acids that are conserved between the Ac-AChBP, α3 nAChR, and α6 nAChR ligand binding sites.
(B) Sequence alignment of Ac-AChBP, rat β2 nAChRs, and rat β4 nAChRs; regions colored with yellow indicate the amino acids that are not conserved between the α3 and α6 ligand binding sites, regions colored blue indicate the amino acids that are conserved between the Ac-AChBP, β2 nAChR, and β4 nAChR ligand binding sites.
We used the standard fixed equipment to position the head so that it could scan in the section in alignment with AC-PC line (anterior commissure-posterior commissure line).
