Direct observation of the Gouy phase shift in THz impulse ranging
(AIP Publishing, 2000-02-07)Here we present a direct observation of the Gouy effect through THz impulse scattering from cylindrical and spherical targets. A pi/2 Gouy phase shift through a one-axis focus compared to the more common pi phase shift of ... -
Direct optoelectronic generation and detection of sub-ps-electrical pulses on sub-mm-coaxial transmission lines
(AIP Publishing, 2004-12-20)We report efficient direct optoelectronic generation of sub-ps-THz pulses on 50 Ohm coaxial transmission lines with a 330 micro-m diameter solid copper outer tube filled with Teflon containing the 80 micro-m diameter inner ... -
Directional growth of polypyrrole and polythiophene wires
(AIP Publishing, 2009-01-23)This work establishes an innovative electrochemical approach to the template-free growth of conducting polypyrrole and polythiophene wires along predictable interelectrode paths up to 30 um in length. These wires have ... -
Disentangling Pauli blocking of atomic decay from cooperative radiation and atomic motion in a 2D Fermi gas
(2021-08-05)The observation of Pauli blocking of atomic spontaneous decay via direct measurements of the atomic population requires the use of long-lived atomic gases where quantum statistics, atom recoil and cooperative radiative ... -
Disinformation and hate speech: Ethnoreligious rhetoric on TikTok during Malaysia’s 15th general election (GE15) 2022
(Safer Internet Lab, 2024-01-17)The 15th Malaysian general election (GE15) on November 19th, 2022, saw the continued use of digital information warfare as a prominent feature in the country’s political landscape. Similar to past elections, various ... -
Disordered flat bands on the kagome lattice
(2018-09-27)We study two models of correlated bond- and site-disorder on the kagome lattice considering both translationally invariant and completely disordered systems. The models are shown to exhibit a perfectly at ground state band ... -
Disruption of morphogenesis and transformation of the suspensor in abnormal suspensor mutants of Arabidopsis
(Company of Biologists, 1994)The suspensor is the first differentiated structure produced during plant embryogenesis. In most angiosperms, the suspensor functions early in development to provide nutrients and growth regulators to the embryo proper. ... -
Distant reading, computational stylistics, and corpus linguistics: The critical theory of digital humanities for literature subject librarians
(Association of College and Research Libraries, 2015) -
Distribution of Culex coronator in the USA
(The American Mosquito Control Association, 2021-03)In 1920, Culex coronator was reported from San Benito, Texas, and later in Arizona, New Mexico, and Oklahoma. In 2005, this species was reported to be spreading across the southeastern USA. Now reported in 14 states, it ... -
DNA probes for detection of copper resistance genes in Xanthomonas campestris pv. Vesicatoria
(American Society for Microbiology, 1991-08)The copper resistance (Cu^r) genes encoded on pXV1OA, a 190-kb plasmid in Xanthomonas campestris pv. vesicatoria XV10, were isolated on a 44-kb cosmid clone designated pCuRl. TnS mutagenesis of pCuRl indicated that a 4.0-kb ... -
Do nonphysical punishments reduce antisocial behavior more than spanking? A comparison using the strongest previous causal evidence against spanking
(BioMed Central, 2010-02-22)Background: The strongest causal evidence that customary spanking increases antisocial behavior is based on prospective studies that control statistically for initial antisocial differences. None of those studies have ... -
Domain wall dynamics in classical spin chains: free propagation, subdiffusive spreading, and topological soliton emission
(2023-06-28)The non-equilibrium dynamics of domain wall initial states in a classical anisotropic Heisenberg chain exhibits a striking coexistence of apparently linear and non-linear behaviours: the propagation and spreading of the ... -
Donor-acceptor nanoensembles of soluble carbon nanotubes
(Royal Society of Chemistry, 2004-08-10)Donor-acceptor nanoensembles, prepared via electrostatic interactions of single wall carbon nanotubes and porphyrin salts, give rise to photoinduced intra-complex charge separation that lasts tens of microseconds. -
Doppler-tuned hyperfine spectroscopy of the lithium ion
(American Physical Society, 1978-11-20)We have used the Doppler-tuned ion-beam, laser-spectroscopy method to measure the hyperfine intervals in the 2^3 S and 2^3 P^o states of Li+. Our resolution was 10 times that of the best previous measurement. In contrast ... -
Double bubbles in S^3 and H^3
(2008-11-20)We prove the double bubble conjecture in the three-sphere S3 and hyperbolic three-space H3 in the cases where we can apply Hutchings theory: 1) in S3, each enclosed volume and the complement occupy at least 10% of the ... -
Down with databases and dead eyes: Reimagining first-year college student instruction for real life
(Oklahoma State University, 2017-10-25)At Oklahoma State University, the approach to first-year student library instruction is undergoing a dramatic shift. Rather than solely rely on traditional tours and orientation sessions that are infrequently adopted by ... -
Dynamic mode decomposition of the metachronal paddling wake
(American Institute of Aeronautics and Astronautics (AIAA), 2023-01-23)Metachronal paddling is a drag-based propulsion strategy observed in many aquatic arthropods in which a series of paddling appendages are stroked sequentially to form a traveling wave in the same direction as animal motion. ... -
Dynamical generation of spin squeezing in ultra-cold dipolar molecules
(2020-11-16)We study a bulk fermionic dipolar molecular gas in the quantum degenerate regime confined in a two-dimensional geometry. Using two rotational states of the molecules we encode a spin 1/2 degree of freedom. To describe the ... -
Dynamics and energy landscape of the jammed spin-liquid
(2018-11-20)We study the low temperature static and dynamical properties of the classical bond-disordered antiferromagnetic Heisenberg model on the kagome lattice. This model has recently been shown to host a new type of spin liquid ...
