“Medium-firm mattresses seem to reduce back pain and improve sleep quality, especially in patients with chronic low back pain,” Morgan said. She added that people with a higher body mass index (BMI) may benefit from a mattress that’s a little firmer, since body weight will impact how supportive a mattress feels to someone.
Funding limitations prevented Nyren from dedicating much time to the project at first, but in 1993, he was finally able to publish a proof-of-principle. His technique began by mixing the template DNA with a primer, a single dNTP, and three enzymes: the familiar DNA polymerase plus the light cascade enzymes, ATP sulfurylase and firefly luciferase.6 If the dNTP was incorporated into a strand of DNA, PPi would be produced in the chemical reaction. ATP sulfurylase could then convert the PPi into ATP, which would provide energy for the luciferase enzyme, producing light. Thus, it was possible to determine each base in the sequence by cycling through the dNTPs one at a time until light was detected, and then washing extra nucleotides out between each step. By literally rinsing and repeating, the sequence could be recorded one letter at a time without the use of any gels, which often took hours to run and were difficult to automate.

there’s a lot of other things that i haven’t even touched on here, like the optimizations we compute ahead of time for specific patterns, how we detect match prefixes, the differences of UTF-16 and UTF-8 matching and unicode, what is the backwards compatibility story, how we can skip through text that others cannot. i haven’t even mentioned Hyperscan, which is a very interesting engine that is actually based on a completely different 1961 paper, and so on, there’s a lot to share so perhaps i will look into these topics in the future.
