Sending signals dynamically.

Proteins mediate transmission of signals along intercellular and intracellular pathways and between the exterior and the interior of a cell. The dynamic properties of signaling proteins are crucial to their functions. We discuss emerging paradigms for the role of protein dynamics in signaling. A central tenet is that proteins fluctuate among many states on evolutionarily selected energy landsca...

Timeline: Sending Out an SOS

Sending Messages in UML

In this paper we try to clarify the issue of associations as a communication infrastructure between objects, in search for a unified view of the static and dynamic aspects of associations. Communication through associations depends on navigability and visibility, therefore the interlacement of these two concepts is examined. But first the very definition of navigability has to be settled, since...

Sending Information Through Status Updates

We consider an energy harvesting transmitter sending status updates regarding a physical phenomenon it observes to a receiver. Different from the existing literature, we consider a scenario where the status updates carry information about an independent message. The transmitter encodes this message into the timings of the status updates. The receiver needs to extract this encoded information, a...

Sending sisters their separate ways

S ister chromatids are often reluctant to separate during mitosis. Germann et al. show that a protein involved in DNA replication and repair helps eliminate lingering connections that can hold sister chromatids together (1). Sister chromatids tangle almost every time a cell enters mitosis. Unless the cell releases these links, the structures can break or fail to separate properly. Two kinds of ...
