    • DNA replication timing and higher-order nuclear organization determine single nucleotide substitution patterns in cancer genomes 

      Liu, Lin; De, Subhajyoti; Michor, Franziska (2013)
      Single nucleotide substitutions (SNS) are a defining characteristic of cancer genomes. Many SNS in cancer genomes arise due to errors in DNA replication, which is spatio-temporally stratified. Here we propose that DNA ...
    • DNA Unzipping Phase Diagram Calculated Via Replica Theory 

      Roland, C. Brian; Hatch, Kristi Adamson; Prentiss, Mara; Shakhnovich, Eugene Isaacovitch (American Physical Society, 2009)
      We show how single-molecule unzipping experiments can provide strong evidence that the zero-force melting transition of long molecules of natural dsDNA should be classified as a phase transition of the higher-order type ...

      We developed molecular tension probes (TPs) that report traction forces of adherent cells with high spatial resolution, can be linked to virtually any surface, and obviate monitoring deformations of elastic substrates. TPs ...
    • DNA-Binding Specificity Changes in the Evolution of Forkhead Transcription Factors 

      Nakagawa, So; Gisselbrecht, Stephen; Rogers, Julia Maria; Hartl, Daniel L.; Bulyk, Martha Leonia (Proceedings of the National Academy of Sciences, 2013)

    • Do Corrupt Governments Receive Less Foreign Aid? 

      Alesina, Alberto; Weder, Beatrice (American Economic Association, 2002)
