The short neuropeptide F (sNPF), a neuropeptide in the central nervous system (CNS) of Drosophila melanogaster, is expressed in a large population of diverse neurons of brain. Most of these neurons are intrinsic interneurons of the mushroom bodies, which are the most prominent insect bilateral CNS structures that regulate memory and sleep. However, its role(More)
MicroRNA-mediated post-transcriptional regulations are increasingly recognized as important components of the circadian rhythm. Here we identify microRNA let-7, part of the Drosophila let-7-Complex, as a regulator of circadian rhythms mediated by a circadian regulatory cycle. Overexpression of let-7 in clock neurons lengthens circadian period and its(More)
In this paper, an adaptive backstepping controller based on nonlinear disturbance observer (DOB) is proposed for the nonlinear fin stabilizer system. DOB is responsible for disturbance rejection and uncertainty compensation, while the adaptive backstepping scheme is proposed for dealing with uncertain parameters of the fin stabilizer model. The designed(More)
