Observation of a Cole-Davidson type complex conductivity in the limit of very low carrier densities in doped silicon
(AIP Publishing, 1998-05-04)Using THz time-domain spectroscopy to measure the complex conductivity of doped silicon from low frequencies to frequencies higher than the THz plasma frequency and the carrier damping rate, we were able to show in the ... -
Observation of a new type of THz resonance of surface plasmons propagating on metal-film hole arrays
(American Physical Society, 2004-11-04)Highly conducting metal-film subwavelength hole arrays, lithographically fabricated on high-resistivity silicon wafers in optical contact with thick silicon plates, have been characterized by terahertz time-domain spectroscopy ... -
Observation of electromagnetic shock waves from propagating surface-dipole distributions
(American Physical Society, 1989-06-19)We have directly measured the time-dependent electromagnetic shock wave generated by an electric surface-dipole distribution propagating faster than the phase velocity in the underlying dielectric substrate. The results ... -
Observation of self-steepening of optical pulses with possible shock formation
(American Physical Society, 1973-08-13)Near-resonant light pulses were steepened by passage through Rb vapor. The rise time changed from typically 4 nsec to less than 1 nsec, and complicated envelopes developed. The self-steepening, well described by adiabatic ... -
Observation of the formation of an optical intensity shock and wave breaking in the nonlinear propagation of pulses in optical fibers
(American Physical Society, 1989-01-30)We have observed the formation of an optical intensity shock and the subsequent wave breaking in the nonlinear propagation of 1-psec pulses in an optical fiber. The wave breaking manifests itself as the appearance of ... -
Observation of the formation of the 0-pi pulse
(American Physical Society, 1984-08-06)We have measured with 0.5-psec resolution the reshaping of small-area 7-psec laser pulses to 0-pi pulses due to their passage through an optically thick sodium cell. The reshaped pulses have a picosecond oscillatory structure ... -
Observation of unitary p-wave interactions between fermions in an optical lattice
(2022-05-27)Exchange-antisymmetric pair wavefunctions in fermionic systems can give rise to unconventional superconductors and superfluids with non-trivial transport properties. The realisation of these states in controllable quantum ... -
Observing metamaterial induced transparency in individual Fano resonators with broken symmetry
(AIP Publishing, 2011-11-15)Metamaterial induced transparency is demonstrated using individual split ring resonators with two gaps on opposite side. For the symmetric structure, only a low quality dipolar resonance is witnessed at a normal incidence ... -
Oklahoma Native Artists Project: Using linked open data to promote oral histories and Native artists
(Oklahoma State University, 2021-07-20)This poster features OSU Library's ongoing case study on improving Oklahoma Native artists' representation through LOD. At the heart of this effort is the Oklahoma Native Artists oral history collection, a project initiated ... -
Oklahoma's news media ecosystem Phase II research: Status and suggestions for local news
(Oklahoma Media Center, 2023-09-13)Access to reliable local news is an essential component of civic life. Particularly in rural communities, local news provides information and promotes community engagement. Despite the importance of local news, data on the ... -
OkstateShakespeare: Bringing special collections and digital humanities into the undergraduate classroom
(Association of College and Research Libraries, 2016)This case study outlines a collaborative, semester-long instructional project for an upper-level undergraduate Shakespeare course at Oklahoma State University (OSU) utilizing the library's rare book resources and digital ... -
Olfactory responses of Amblyomma maculatum to rumen fluid and other odourants that attract blood-seeking arthropods
(Wiley, 2020)Amblyomma maculatum Koch (Ixodida: Ixodidae) has emerged as a significant vector of human and companion animal diseases in the U.S.A. When expanding in range, A. maculatum can be difficult to collect in the field and control ... -
On combinatorics of the Arthur trace formula, convex polytopes, and toric varieties
(Cambridge University Press, 2022-01-27)We explicate the combinatorial/geometric ingredients of Arthur’s proof of the convergence and polynomiality, in a truncation parameter, of his noninvariant trace formula. Starting with a fan in a real, finite dimensional, ... -

On knot complements that decompose into regular ideal dodecahedra
(2012-09-05)Aitchison and Rubinstein constructed two knot complements that can be decomposed into two regular ideal dodecahedra. This paper shows that these knot complements are the only knot complements that decompose into n regular ... -
On manifolds with multiple lens space filings
(2013-08-22)An irreducible 3--manifold with torus boundary either is a Seifert fibered space or admits at most three lens space fillings according to the Cyclic Surgery Theorem. We examine the sharpness of this theorem by classifying ... -
On the complexity of cusped non-hyperbolicity
(2019-07-02)We show that the problem of showing that a cusped 3-manifold M is not hyperbolic is in NP, assuming S3-RECOGNITION is in coNP. To this end, we show that IRREDUCIBLE TOROIDAL RECOGNITION lies in NP. Along the way we ... -
On the geometry dependence of differential pathlength factor for near-infrared spectroscopy. I. Steady-state with homogeneous medium
(SPIE, the international society for optics and photonics, 2015-10-14)This work analytically examines some dependences of the differential pathlength factor (DPF) for steady-state photon diffusion in a homogeneous medium on the shape, dimension, and absorption and reduced scattering coefficients ... -
On the stress-induced photon emission from organism: I, will the scattering-limited delay affect the temporal course?
(Springer Nature, 2020-08-27)Much remains to be identified for the temporal course of stress-induced photon emission (PE) from organism following stress of various types including but not limited to light. Induced PE concerns surface light emission ... -
On the stress-induced photon emission from organism: II, how will the stress-transfer kinetics affect the photo-genesis?
(Springer Nature, 2020-08-25)Much remains to be identified for the temporal course of stress-induced photon emission (PE) following stress of various types including but not limited to light. Induced PE often decays hyperbolically; yet, it is not ...
