Feedback delay networks (FDNs) are often used in the context of artificial reverberation and are a class of sparse IIR filters. FDNs are based on a feedback loop with multiple channels containing delay elements, as well as a mixing matrix providing a connection between the channels. An example of a simple FDN is shown in Figure 1. For a practical FDN implementation, many parameters have to be c...
Transport through nano-channels plays an important role in many biological processes and industrial applications. Gaining insights into the functioning of biological transport processes and the design of man-made nano-devices requires an understanding of the basic physics of such transport. A simple exclusion process has proven to be very useful in explaining the properties of several artificia...
A B $ T R A C T The effect of tetrodotoxin on the sodium currents of the squid (Doryteuthis plei and Sepioteuthis sepiodea) giant axons was studied under potential control conditions. The axons were immersed in artificial seawater at 21°C and pH 7.5. When the effect of the toxin is studied in concentrations ranging from 0.1 to 50 nM the Eadie-Haldane plot is not a straight line and indicates th...
The pore-forming toxin lysenin self-inserts to form conductance channels in natural and artificial lipid membranes containing sphingomyelin. The inserted channels exhibit voltage regulation and hysteresis of the macroscopic current during the application of positive periodic voltage stimuli. We explored the bi-stable behavior of lysenin channels and present a theoretical approach for the mechan...

Piezo ion channels are activated by various types of mechanical stimuli and function as biological pressure sensors in both vertebrates and invertebrates. To date, mechanical stimuli are the only means to activate Piezo ion channels and whether other modes of activation exist is not known. In this study, we screened ~3.25 million compounds using a cell-based fluorescence assay and identified a ...
