Docosahexaenoic acid (DHA), the end-product of the metabolism of omega-3 family fatty acids, is the main polyunsaturated fatty acid of the brain, but its accumulation is incompletely understood. This paper reviews how it could accumulate through specific uptake of DHA-containing lysophosphatidylcholine (LysoPC-DHA). DHA migrates very easily from the sn-2(More)
may be unknown since the urea-to-ammonia conversion process can be delayed downstream to the catalysts or even be incomplete. To help addressing these issues, Lyapunov-based observers are proposed in this study to estimate the ammonia coverage ratio, actual ammonia concentration input, and the total ammonia slip, for a urea-SCR system during low-temperature(More)
