Split-hom together structure is a new heavy load rack structure, and its reliability needs to be verified. Through analyzing multimodal hom-connection principle from the perspective of bionics and contact mechanics, the article puts forward three kinds of hom-connection methods and establishes the finite element model and mathematical model of the rack. Afterwards, the finite element model and ...

Transcript quantification techniques usually rely on purified mRNAs. We report here a solution-based sandwich hybridization assay for the quantification of mRNAs from Escherichia coli without the need of prior RNA isolation. This assay makes use of four DNA oligonucleotide probes adjacently hybridizing to target RNA in clarified cell extracts. Two helper probes facilitate the hybridization of a...
