In this paper, we discuss information transfer through calcium signaling, one form of molecular communication that is ubiquitously used in natural biological systems and that is potentially useful to design synthetic biological systems. We use a mathematical model to describe a molecular communication system in which a transmitter communicates information with the receiver over a calcium signal...

Transfer entropy provides a general tool for analyzing the magnitudes and directions—but not the kinds—of information transfer in a system. We extend transfer entropy in two complementary ways. First, we distinguish state-dependent from state-independent transfer, based on whether a source’s influence depends on the state of the target. Second, for multiple sources, we distinguish between uniqu...

We propose a scheme for the transfer of quantum information among distant qutrits. We apply this scheme to the distribution of entanglement among distant nodes and to the generation of multipartite antisymmetric states. We also discuss applications to quantum secret sharing. PACS numbers: 3.67.Mn, 3.65.Ud, 3.67.-a

During Assisted Reproductive Technology (ART) procedures, the transfer of a single embryo dramatically reduces the rate of multiple pregnancy. Proper information, therefore, should be delivered to patients before embryo transfer. In many countries, regulations limit, according to age of the patient, the number of embryos to be transferred. Selective fetal reduction should not be considered as a...
