There is no standard notation called Q (matrix). However in this case I think the matrix that they are referring to is the state transition matrix (similar to the adjacency matrix as mentioned by Justas in the comments, but with rates instead of just the connections). Basically you have three states (lets call them A, B and C) and there is a rate for ...

Another source of developmental noise is due to diffusion. Diffusive processes are stochastic and induce noise in morphogen gradients and results in the concentration as being "jagged". Recent results have directly measured the noise in morphogen gradients of the developing zebrafish. In fact, when you think about the low copy numbers of transcription ...

This is an interesting phenomenon which I have been aware of for several years, but I haven't yet come across any official description of it or explanation for it. Nonetheless, the phenomenon is easy to explain. It is a result of light adaptation in your retina responding to different levels of light being received by each eye. Background The level of ...

The absorbed dose describes the amount of radiation absorbed by an object or person, i.e., the amount of energy that radioactive sources deposit in materials through which they pass. The units for absorbed dose are the radiation absorbed dose (rad), or better: the gray (Gy) unit. One gray dose is equivalent to one joule radiation energy absorbed per ...
