    • Tailoring the slow light behavior in terahertz metasurfaces 

      Manjappa, Manukumara; Chiam, Sher-Yi; Cong, Longqing; Bettiol, Andrew A.; Zhang, Weili; Singh, Ranjan (AIP Publishing, 2015-05-04)
      We experimentally study the effect of near field coupling on the transmission of light in terahertz metasurfaces. Our results show that tailoring the coupling between the resonators modulates the amplitude of resulting ...

      Ecological theory predicts that diversity decreases variability in ecosystem function. We predict that, at the landscape scale, spatial variability created by a mosaic of contrasting patches that differ in time since ...

    • Terahertz conductivity of thin metal films 

      Laman, N.; Grischkowsky, D. (AIP Publishing, 2008-08-05)
      The conductivities of thin Al, Au, and Ag films were measured via their transmission at terahertz frequencies. The conductivities of all the films, particularly the thinner films and Al films, were much smaller than their ...

      We report the coupling and guiding of broadband terahertz radiation using a two-cylinder waveguide coupler. For the transverse electromagnetic TEM (TM0) geometry, the two opposing metal cylinders exhibit an amplitude ...

    • Terbinafine resistance mediated by salicylate 1-monooxygenase in Aspergillus nidulans 

      Graminha, Marcia A. S.; Rocha, Eleusa M. F.; Prade, Rolf A.; Martinez-Rossi, Nilce M. (American Society for Microbiology, 2004-09)
      Resistance to antifungal agents is a recurring and growing problem among patients with systemic fungal infections. UV-induced Aspergillus nidulans mutants resistant to terbinafine have been identified, and we report here ...

    • Testing the ecological consequences of evolutionary change using elements 

      Jeyasingh, Punidan D.; Cothran, Rickey D.; Tobler, Michael (Wiley Open Access, 2014)
      Understanding the ecological consequences of evolutionary change is a central challenge in contemporary biology. We propose a framework based on the ~25 elements represented in biology, which can serve as a conduit for a ...

    • That face when your class is fake news: Critical librarianship in the for-credit classroom 

      Luetkenhaus, Holly; Upson, Matt; Colquhoun, Cristina (Oklahoma State University, 2018-07-20)
      Librarians at Oklahoma State University have developed a three-credit course titled, 'They Wouldn't Put it on the Internet if It's Not True: Information Literacy in a Post-truth Society.' This course, first offered during ...

    • The best keying protocol for sensor networks 

      Choi, Taehwan; Acharya, HB; Gouda, Mohamed G (Elsevier, 2013-08)
      Many sensor networks, especially mobile networks or those networks that are deployed to monitor crisis situations, are deployed in an arbitrary and unplanned fashion. Thus, any sensor in such a network may end up being ...
