      Industrial wastewaters and urban discharges contain complex mixtures of chemicals capable of impacting reproductive performance in freshwater fish, called endocrine-disrupting compounds (EDCs). In Chile, the issue was ...
    • Endocrine Regulation of Phosphate Homeostasis 

      Brown, Ronald B.; Razzaque, Mohammed S. (Elsevier, 2018)
      Phosphate, a component of nucleic acids, DNA and RNA, is incorporated in the structure of phospholipids in cell membranes, and is involved in many biological functions such as cell signaling, energy metabolism, and bone ...
    • Energy Consumption Analysis of XRP Validator 

      Roma, Crystal; Hasan, M. Anwar (2020)

      Inspired by the experimental measurement of the Rényi entanglement entropy in a lattice of ultracold atoms by Islam et al. [Nature (London) 528, 77 (2015)], we propose a method to entangle two spatially separated qubits ...
    • Entropic Matroids and Their Representation 

      Abbe, Emmanuel; Spirkl, Sophie (Multidisciplinary Digital Publishing Institute, 2019)

    • Entropic segregation of short polymers to the surface of a polydisperse melt 

      Mahmoudi, Pendar; Matsen, Mark (Springer, 2017)
      Chain ends are known to have an entropic preference for the surface of a polymer melt, which in turn is expected to cause the short chains of a polydisperse melt to segregate to the surface. Here, we examine this entropic ...
