    • The F [subscript N] method for a bare critical cylinder 

      Southers, Jack Daniel (Virginia Polytechnic Institute and State University, 1982)
      The FN method, originated by C. E. Siewert, is developed for a bare, axially infinite critical cylinder. The full-range completeness and orthogonality properties of the singular eigenfunctions are used to derive ...
    • F-spondin Is Essential for Maintaining Circadian Rhythms 

      Carrillo, Gabriela L.; Su, Jianmin; Monavarfeshani, Aboozar; Fox, Michael A. (Frontiers, 2018-02-08)
      The suprachiasmatic nucleus (SCN) is the master pacemaker that drives circadian behaviors. SCN neurons have intrinsic, self-sustained rhythmicity that is governed by transcription-translation feedback loops. Intrinsic ...
    • F-theory on quotient threefolds with (2,0) discrete superconformal matter 

      Anderson, Lara B.; Grassi, Antonella; Gray, James; Oehlmann, Paul-Konstantin (Springer, 2018-06-20)
      We explore 6-dimensional compactifications of F-theory exhibiting (2, 0) superconformal theories coupled to gravity that include discretely charged superconformal matter. Beginning with F-theory geometries with Abelian ...
    • An F-theory realization of the chiral MSSM with Z(2)-parity 

      Cvetič, Mirjam; Lin, Ling; Liu, Muyang; Oehlmann, Paul-Konstantin (Springer, 2018-09-17)
      Using F-theory we construct 4D N = 1 SUGRA theories with the Standard Model gauge group, three chiral generations, and matter parity in order to forbid all dimension four baryon and lepton number violating operators. The ...

      Silk, Robert (Travel Weekly, 2021-03-31)
      A Congressional mandate from 2018 stated that the FAA set standards for seat width, and space between rows. These specifications have required a measure of safety in determining that aircraft were being properly tested ...
    • FAA Believes Most Airlines Won’t Weigh Passengers 

      Thomaselli, Rich (Travel Pulse, 2021-05-19)
      •The Federal Aviation Administration doesn’t believe airlines will resort to weighing passengers prior to flights, saying guidance it issued two years ago regarding weight and balance on planes inexplicably blew up into a ...
