Deterministic Context-Free Languages are Closed Under Complementation
K Taskin, T Nipkow
A deterministic context-free language (DCFL) is a language accepted by a deterministic pushdown automaton This entry proves that they are closed under complementation, following Hopcroft and Ullman (1979).

My Berkeley colleagues & I are saddened by the death of our colleague Robin Lakoff. Her 1972 book Language & Women's Place created the modern field of language & gender. She also wrote articulately, passionately & impactfully about Latin linguistics (Abstract Syntax & Latin Complementation, 1968) 1/

Happy to have contributed to this big story. We present new genome assemblies, genus-wide complementation and allele-specific expression analyses in hybrids between zebrafish and closely related Danio species with divergent pigment patterns. A vertebrate model genus for basic comparative biology.

Hello, I’m a disruptor, very smart, here to create efficiency. I’m just going to drill holes in the bottom of this boat to see which parts of the hull are mission-critical.

Notwithstanding the concerning news about the future of science in the US, I successfully cloned two proteins for bifluorescence complementation in tobacco leaves. I also plan to do patch clamp experiments in plant vacuoles and eventually obtain a cryo-EM structure. Having fun doing science!

I don’t line to brag, but I think I may have just carried out the least conclusive complementation test in the history of genetics.
Thanks you.

Mainstream artistic color theory (primary colors, RYB, complementation, recede/advance) is completely wrong and makes the world uglier.

Meet AbpX, a biomatrix protein from the hyperthermophile Pyrodictium abyssi. It forms Ca²⁺-triggered fibrils via donor strand complementation. Using cryo-EM + X-ray, we built a full lattice model and place AbpX in a new TasA superfamily clade.
A very nice collaborative project!

• La complémentation en vit. #B12 est en effet indispensable pour les personnes véganes, mais aussi – ce n'est pas précisé dans l'article – pour toute personne mangeant de la chair animale (terrestre ou aquatique) à moins de la moitié des repas.
Les personnes végé/flexi sont donc concernées aussi.

My grants: genetic complementation in cis or in trans; cis- and trans-SNARE protein complexes that drive membrane fusion in cells; the cis- and trans-Golgi organelle. Cis- and trans-fatty acids.
All of this is so profoundly, deeply, catastrophically idiotic.

Duke appears to have lost NIH grants because they used the prefix "trans" in reference to disease transmission, transgenic genetic material, translational studies, or signal transduction www.dukechronicle.com/article/2025...
