'no crossing' is correct and can be used in written English.
You can use it when you want to express that something (or someone) should not cross a certain line. For example, "There is a 'no crossing' sign in front of the river to warn people not to try to cross it."
The simulation results show that three fundamental crossing scenarios can be well reproduced: (I) Direct Crossing, (II) Offset Crossing and (III) No Crossing (Arrested), and the crossing types agree well in the evaluation by Blanton's criterion.
The "no crossing swords" dictum seemed uptight, not humorous.
Teaching children to "just say no," crossing our fingers, and saying a prayer is not enough.
"There are approximately six street crossings, most with no crossing guards," Hernandez said.
No crossing anything out.
However, most previous curve detection algorithms are usually applied in simple or no crossing situations.
Because the number of polymorphic sites for the genes in the no-crossing-over (N) category is too small to conduct statistical tests on allele frequency spectra, we combined the no-crossing over genes with those from the low crossing-over category (L) and compared these genes (0 2.93 cM/Mb) with those from the high-crossing-over category (>2.93 cM/Mb).
As there is no crossing-over in female Lepidoptera [52], [53], this Am locus must be located on a different chromosome than Pher.
The authors show only cases in which the R and G markers are in cis, which implies that during selfing, there has been no crossing-over between them.
In some P. anserina meioses, there is no crossing-over between the centromere and the mat locus (or an even number of them on the same chromatids), leading to the formation of 2 homokaryotic mat+ and 2 homokaryotic mat− ascospores.
The lowest Fop values are on the fourth chromosome, suggesting that selection is least efficient on this chromosome, possibly due to a longer history of no crossing-over in this region than other regions that lack crossing-over (Haddrill et al. 2007), or a larger concentration of genes in a single genomic region that lacks crossing-over (KA /KS is also highest for the fourth chromosome).
