    • Achievable Rates for Arbitrary Network Topologies with â Cheapâ Nodes 

      Khojastepour, Mohammad; Sabharwal, Ashutosh; Aazhang, Behnaam (2003-05-01)
      In this paper, we derive achievable rates for arbitrary network topologies consisting of â cheapâ nodes. A node is labeled â cheapâ if its radio can only operate in TDD mode when transmitting and receiving in the ...
    • Cut-set Theorems for Multi-state Networks 

      Khojastepour, Mohammad; Aazhang, Behnaam; Sabharwal, Ashutosh (2003-10-01)
      We derive new cut-set bounds on the achievable rates in a general multi-terminal network with finite number of states. Multiple states are common in communication networks in the form of multiple channel and nodes' states. ...
    • Ultrasensitivity of the Bacillus subtilis sporulation decision 

      Narula, Jatin; Devi, Seram N.; Fujita, Masaya; Igoshin, Oleg A. (2012-11-19)
      Starving Bacillus subtilis cells execute a gene expression program resulting in the formation of stress-resistant spores. Sporulation master regulator, Spo0A, is activated by a phosphorelay and controls the expression ...
