We present an approach that allows rapid determination of the topology of Escherichia coli inner-membrane proteins by a combination of topology prediction and limited fusion-protein analysis. We...

Experimentally based topology models for E. coli inner membrane proteins
Rapp, Mikaela, Drew, David, Daley, Daniel O., Nilsson, Johan, Carvalho, Tiago, Melén, Karin, ...
Membrane protein topology predictions can be markedly improved by the inclusion of even very limited experimental information. We have recently introduced an approach for the production of reliable...
Prediction of partial membrane protein topologies using a consensus approach
Nilsson, Johan, Persson, Bengt, Von Heijne, Gunnar
We have developed a method to reliably identify partial membrane protein topologies using the consensus of five topology prediction methods. When evaluated on a test set of experimentally...
Stochastic Analysis and Control of Real-Time Systems with Random Time Delays
Johan Nilsson, Bo Bernhardsson, Björn Wittenmark
The paper discusses modeling and analysis of real-time systems subject to random time delays in the communication network. A new method for analysis of different control schemes is presented. The...
