Optimisation of air-distributor channel structural parameters based on Taguchi orthogonal design

, 2020
Air distributors are a typical kind of ventilation terminal that are widely used in air-conditioning systems. However, the high flow resistance of traditional air distributors leads to huge energy losses and poor indoor thermal comfort.

The Theory of Quaternion Orthogonal Designs

IEEE Transactions on Signal Processing, 2008
Over the past several years, there has been a renewed interest in complex orthogonal designs for their application in space-time block coding. Motivated by the success of this application, this paper generalizes the definition of complex orthogonal designs by introducing orthogonal designs over the quaternion domain. This paper builds a theory of these

A 68-codon genetic code to incorporate four distinct non-canonical amino acids enabled by automated orthogonal mRNA design

Nature Chemistry, 2021
Orthogonal (O) ribosome-mediated translation of O-mRNAs enables the incorporation of up to three distinct non-canonical amino acids (ncAAs) into proteins in Escherichia coli (E. coli). However, the general and efficient incorporation of multiple distinct
