Fillover

Fillover refers to a phenomenon observed in certain types of data or measurement systems where a value, after reaching a peak or a threshold, begins to "fill over" or decline. This term is not a standard scientific or technical term and is often used informally in specific contexts.

One common context for fillover is in the analysis of sensor data or time-series measurements. For instance, if a sensor is designed to detect a specific substance and its reading increases as the substance concentration rises, a fillover might describe a situation where the reading starts to decrease even though the substance concentration is still present or even increasing. This could be due to sensor saturation, degradation, or interference from other factors.

In some experimental or modeling scenarios, fillover can also describe a process where a system that has reached a maximum capacity or state begins to reverse or dissipate. For example, in certain chemical reactions or biological processes, a rapid accumulation might be followed by a gradual decrease as the system seeks equilibrium or undergoes breakdown. The term implies a transition from an increasing or stable state to a decreasing one, often after a peak.

Understanding fillover in any given context requires examining the underlying mechanisms of the system being observed. It is crucial to identify the causes of the decline after a potential rise to accurately interpret the data and draw valid conclusions.
