Cover Story: Permeation through a potassium channel is quickly terminated after it opens via selectivity filter inactivation. This process is essential to functioning potassium channels, including bacterial KcsA. We compared the behavior of the wild-type KcsA channel and its mutants using molecular dynamic simulations, identifying residues with distinct properties. By analyzing causal links between rearrangements of these residues and permeating ions, we unraveled a network that acts as a self-organized system in regulating the ion permeation. Changes in one part of the network can lead to an adaptation in other regions, and the network can dynamically switch to an inactive state. View this paper.

In this paper, we consider a scenario where the base station (BS) collects time-sensitive data from multiple sensors through time-varying and error-prone channels. We characterize the data freshness at the terminal end through a class of monotone inc...

In the nervous system, information is conveyed by sequence of action potentials, called spikes-trains. As MacKay and McCulloch suggested, spike-trains can be represented as bits sequences coming from Information Sources (IS). Previously, we studied r...

Tail-biting convolutional codes extend the classical zero-termination convolutional codes: Both encoding schemes force the equality of start and end states, but under the tail-biting each state is a valid termination. This paper proposes a machine le...
