Closed-loop Acceleration Feedback
Historically, sensor noise has been a key factor in the analysis of system performance for formation flying spacecraft. Since most interesting formation missions require coordination between multiple spacecraft, knowledge of the relative states must be as accurate as possible. This knowledge is typically used to design a trajectory to meet specific criteria, such as minimizing fuel use or maint...
متن کاملFeedback on a feedback loop: the hypothalamic-pituitary-gonadal axis.
Recent evidence indicates that transthyretin (TTR), the major transport protein for thyroxine [1] and retinol binding protein [2], plays important roles in amyloidβ (Aβ) metabolism. Transthyretin has been demonstrated to bind Aβ in vitro [3,4] and in vivo [5,6], colocalize in Aβ plaques and within neurons containing intracellular Aβ [7], and recent evidence suggests it might act as a transport ...
متن کاملOscillations by the p53-Mdm2 feedback loop.
The p53 network is perhaps the most important pathway involved in preventing the initiation of cancer, p53 levels and activity are upregulated in response to various stresses including DNA damage, hypoxia, and oncogene activation. Active p53 initiates different transcriptional programs that result in cell cycle arrest, cellular senescence or apoptosis. p53 also activates the transcription of Md...
متن کاملClosing the Loop: Feedback at Your Fingertips
The global network we call the Internet today was started a few decades ago following a very simple model. The entities involved in the beginning had very simple (stated) goals and interaction between them was consequently simple. Technological advances in the recent years have brought exciting new capabilities for Internet users they can access the Internet from almost anywhere using mobile de...
متن کاملCore genetic module: the mixed feedback loop.
The so-called mixed feedback loop (MFL) is a small two-gene network where protein A regulates the transcription of protein B and the two proteins form a heterodimer. It has been found to be statistically over-represented in statistical analyses of gene and protein interaction databases and to lie at the core of several computer-generated genetic networks. Here, we propose and mathematically stu...
