Riboswitches are cis-acting regulatory RNA elements prevalently located in the leader sequences of bacterial mRNA. An adenine sensing riboswitch cis-regulates adeninosine deaminase gene (add) in Vibrio vulnificus. The structural mechanism regulating its conformational changes upon ligand binding mostly remains to be el...

The reconstruction of a central tendency `species tree' from a large number of conflicting gene trees is a central problem in systematic biology. Moreover, it becomes particularly problematic when taxon coverage is patchy, so that not all taxa are present in every gene tree. Here, we list four apparently desirable pr...

Linking structure and activity in nonlinear spiking networks
We were recently made aware of an error in this article: in Figure 13, we neglected several one-loop contributions to the two-point correlation. For the networks we studied here, these contributions are small (third order in the coupling strength). For further discussion, please see the correction note appended...
