... upper left pixel in the first image and the lower right pixel in the second image—their random fluctuations over time are eerily similar—one could predict many of the properties in the second pixel ...

... learning is due to the particular method used to induce forgetting. If forgetting is induced by random fluctuations in the strength of synaptic connections, then free-lunch learning will be observed ...

... computing and communications systems. Conventional amplifiers add unwanted “noise,” or random fluctuations, when they measure and boost electromagnetic signals. Amplifiers that theoretically add no ...

... and reacting with one another. Second, cells are extremely tiny; therefore sensitive to random fluctuations in the number of molecules being created or destroyed at any given moment." Nonetheless, ...

... the dynamics of each system has unknown parameters and that the data are distorted by random fluctuations, the researchers from California and Lancaster were able to successfully recreate measurements ...

... changes in the relative frequencies—or penetrance—of those forms. "It's interesting that noise—these random fluctuations of proteins in the cell—is critical for this to work," he continues. "Noise ...

... on the environmental conditions. Biological "noise" in the genetic circuit, which comes from random fluctuations in the chemical reactions involved in the pattern of interactions, is similar to ...

... focus in on the predictable, repeating pitch of the friend's voice and effectively tune out the random, fluctuating background noise. Although it may be a routine occurrence, exactly how the nervous ...
