This gives us a simple way to determine whether this loop will produce stabilization (negative feedback) or a runaway process (positive feedback). In addition to the sign of a causal connection, we also need to take into account the delay or lag between cause and effect, e.g., the ...
Negative feedback loop involving two cascaded simple regulations with the Laplace transform of the basal production rate F0,Z(s) added.YongJun, ShinLeonidas, Bleris
Robust, Tunable Biological Oscillations from Interlinked Positive and Negative Feedback Loops A simple negative feedback loop of interacting genes or proteins has the potential to generate sustained oscillations. However, many biological oscillators... YC Tsai,YS Choi,W Ma,... - 《Science》 被引量...
Here, we tested our hypothesis that the widespread symbiotic relationships between cnidarians and their dinoflagellate symbionts in the family Symbiodiniaceae are based on a simple carbon-nitrogen negative feedback loop. This basic metabolic interaction allows cnidarian hosts to control symbiont proliferatio...
Such degeneracy provides a sufficient-and-necessary condition for the simple Hopf bifurcation. We shall apply these theories to the models on genetic negative feedback loops in Section 3. Consider a system of ODEsx˙=f(x;p), where x=(x1,…,xm)∈Rm,f=(f1,…,fm)∈C∞, and p∈Rp ...
Negative feedback Jump to navigationJump to search Feedback is actually a quite simple thing. As the name suggests, part of the output signal is "fed back" to the input of the poweramp. This signal adds to the signal coming from the preamp and is amplified by the poweramp again. The ...

MKK3 cascade mediates the negative feedback loop of ABA signal through the interaction between OsMPK7 and core ABA signaling components in rice. Background Seed dormancy inhibits seed germination under adverse environment conditions and increases the survival and fitness of wild plants. For rice, dorma...
we demonstrate that two ERF family transcription factors, ERM1 and ERF12, together with WRI5a, can form a negative feedback loop that functions as a central module for fine-tuning of arbuscule development inMedicago. We propose that this may serve to limit excess resource expenditure and stabil...
1.3HPA feedback function HPA feedback activity is measured by the rate at which cortisol levels decline following offset of a stressor and is influenced by a variety of factors, including functioning of the feedback arm of the HPA-axis and cognitive and affective processes (McEwen, 1998). The...
