Negative feedback is not the only type of feedback control that exists. The human body also uses positive feedback loops. In positive feedback, the signal continues to be amplified. The relationship between the signal and the response to the signal is direct, meaning that both the signal and...
The feedback loop is information that is obtained from a reaction about the product and this will be used to alter the product. Therefore, the feedback loop in biology will be defined as a system of altering the reaction based on the type of product formed. It is an ...
the engine thus speeds up. It is the dynamic balance between the opening of the valve (“positive feedback”) and the closing of the valve (“negative feedback”) that enables the steam engine to maintain a constant speed. This interaction between positive and negative feedbacks permits the ...

Bistability is ubiquitous in biological systems. For example, bistability is found in many reaction networks that involve the control and execution of important biological functions, such as signaling processes. Positive feedback loops, composed of speci
Cell signaling systems that contain positive-feedback loops or double-negative feedback loops can, in principle, convert graded inputs into switch-like, irreversible responses. Systems of this sort are termed ‘bistable’. Recently, several groups have engineered artificial bistable systems into Escheri...
we found that the expression of miR-16-5p is largely induced by EV71, meaning that EV71 infection promotes the pri-miR-16-1 process into mature miR-16-5p. As the host gene of miR-16-1, the primary transcript of DLEU2 contains the pri-miR-16-1 sequences, which can further be proces...
to capture the mechanisms controlling microbial physiology we incorporated the mass specific rates of these processes in the model as previously45. It is important to highlight that a substantial fraction of CUE variation remains unexplained in the model, meaning that other important factors are not ...

The term "plus" can also imply a benefit or an addition in non-mathematical contexts, such as "a plus point" meaning an advantage. Conversely, "positive" is widely used to describe optimistic attitudes, affirmative answers ("a positive response"), or conditions ("positive feedback"), reflect...
