  • Physical and Functional Compartmentalization of Archaeal Chromosomes. [Journal Article]
    Cell 2019; 179(1):165-179.e18Takemata N, Samson RY, Bell SD
  • The three-dimensional organization of chromosomes can have a profound impact on their replication and expression. The chromosomes of higher eukaryotes possess discrete compartments that are characterized by differing transcriptional activities. Contrastingly, most bacterial chromosomes have simpler organization with local domains, the boundaries of which are influenced by gene expression. Numerou…
  • Beating to rotational transition of a clamped active ribbon-like filament. [Journal Article]
    Soft Matter 2019Anand SK, Chelakkot R, Singh SP
  • We present a detailed study of a clamped ribbon-like filament under a compressive active force using Brownian dynamics simulations. We show that a clamped ribbon-like filament is able to capture beating as well as rotational motion under the compressive force. The nature of oscillation is governed by the torsional rigidity of the filament. The frequency of oscillation is almost independent of the…
  • Machine Learning Protocol for Surface Enhanced Raman Spectroscopy. [Journal Article]
    J Phys Chem Lett 2019Hu W, Ye S, … Jiang J
  • Surface-enhanced Raman spectroscopy (SERS) is a powerful technique that can capture the electronic-vibrational 'finger-print' of molecules on surfaces. Ab. initio. prediction of Raman response is a long-standing challenge because of the diversified interfacial structures. Here we show that a cost effective machine learning (ML) random forest method can predict SERS signals of a trans-1,2-bis (4-p…
