The phrase "a periodical pattern" is correct and usable in written English.
It can be used to describe a recurring or repeating sequence or arrangement that occurs at regular intervals.
Example: "The study revealed a periodical pattern in the data, indicating seasonal fluctuations in sales."
Alternatives: "cyclical pattern" or "repetitive pattern".
This study investigates the optimization of a hybrid composite/elastomer sandwich plate structure using a periodical pattern of viscoelastic material.
These results may have clinical significance given that in chronic inflammatory airway diseases increased acetylcholine release is observed in a periodical pattern, for example during asthma attacks [ 2].
We herein reported a periodical pattern of SNP density distribution around the transcription start sites (TSSs) that are associated with CpG islands (CGIs).
Second, we use the Fisher's G-test to examine whether the expression or activity of a TF behaves like a pure random process or whether it shows a periodical pattern.
In this study we examined the impact of WRN on telomeric substrates with a 3' single-stranded overhang in vitro and show that WRN has sequence-specific exonuclease activity that removes several nucleotides inward with a periodical pattern from the 3' end of the telomeric overhang.
The sequence divergence of the same genomic region between humans and chimpanzees also revealed a similar periodical pattern.
These iRASs show a significant periodical pattern (P = 3e-10, Fisher's G test), while the expression levels of E2F4 do not (P >0.1, Fisher's G test).
An analysis of the sequence divergence of the same genomic regions between humans and chimpanzees also revealed a similar periodical pattern in CGI.
Trifonov [20] found a universal three-base periodical pattern (G-non-G-N) in protein coding sequences and suggested that this pattern in mRNA may be responsible for monitoring the correct reading frame during translation.
In the latter study, the authors utilize DESeq2's likelihood ratio test in a set-up analogous to ours (Time and Phenotype factors) to demonstrate that a group of genes lose the periodical pattern of expression.
For this, the nucleosomal DNA AA/TT periodical pattern was used, derived from a collection of experimentally mapped nucleosomes [ 45].
