Molecular switch architecture determines response properties of signaling pathways
Many intracellular signaling pathways are composed of molecular switches, proteins that
transition between two states—on and off. Typically, signaling is initiated when an external …

[HTML][HTML] Characterizing the role of autaptic feedback in enhancing precision of neuronal firing times
In a chemical synapse, information flow occurs via the release of neurotransmitters from a
presynaptic neuron that triggers an Action potential (AP) in the postsynaptic neuron. At its …

Moment analysis of linear time-varying dynamical systems with renewal transitions
Stochastic dynamics of several systems can be modeled via piecewise-deterministic time
evolution of the state, interspersed by random discrete events. Within this general class of …
