      Nakatsuka, Hiroki; Grischkowsky, D.; Balant, A. C. (American Physical Society, 1981-09-28)
      The predictions of the nonlinear Schrodinger equation have been tested by passing 5.5-psec optical pulses through a 70-m single-mode optical fiber. With use of a precise cross correlation technique based on pulse compression, ...
    • Norms of products and factors polynomials 

      Pritsker, Igor E (2001-01-19)
      We study inequalities connecting a product of uniform norms of polynomials with the norm of their product. Generalizing Gel’fond-Mahler inequality for the unit disk and Kneser-Borwein inequality for the segment [−1,1], we ...

      Background: Small RNAs regulate a number of developmental processes in plants and animals. However, the role of small RNAs in legume-rhizobial symbiosis is largely unexplored. Symbiosis between legumes (e.g. soybean) and ...
    • Novel approach to identify inhibitors of iron acquisition systems of Pseudomonas aeruginosa 

      Kannon, Mamie; Nebane, N. Miranda; Ruiz, Pedro; McKellip, Sara; Vinson, Paige N.; Mitra, Avishek (American Society for Microbiology, 2022-07-13)
      Pseudomonas aeruginosa is an opportunistic pathogen that has been declared by the World Health Organization as a “priority 1 critical pathogen” needing immediate new strategies for chemotherapy. During infection, P. ...
