Mattis, Daniel C.; Sutherland, Bill | Ambiguities with the relativistic δ-function potential | In many cases of physical interest, the 6-function potential is a very convenient approximation to more structured, and more difficult, short-ranged potentials. In relativistic theories, its use is often mandated because only a mathematical point has a relativistically invariant shape. Neverthele... | Delta function; Energy states | 1981-09 |

Vardeny, Zeev Valentine; Gellermann, Werner | Amplified resonant Raman scattering in conducting polymer thin films | Using picosecond pulsed laser excitation, we investigate the optical emission characteristics of poly(2,5-dioctyloxy-p-phenylenevinylene), (DOO-PPV), thin films at high excitation intensities (~1-90 MW/cm2). We observe the presence of amplified resonance Raman scattering in the emission spectra of c... | Amplified resonant Raman scattering; High excitation intensities; pi-conjugated polymers | 1998 |

Vardeny, Zeev Valentine; Ehrenfreund, Eitan A. | Amplitude and phase modes in trans-polyacetylene: resonant Raman scattering and induced infrared activity | The resonant Raman scattering (RRS) from the three Ag modes of trans-polyacetylene and the charged-induced ir modes are analyzed with use of the amplitude- and phase-mode theories. It is shown that the observed phonon frequencies and the relative intensities of all modes obtained at various laser ex... | Induced infrared activity; Ag modes; Amplitude modes; Phase modes; Trans-polyacetylene | 1987-07 |

Stevens, Kenneth | An A-FPGA architecture for relative timing based asynchronous designs | This paper presents an asynchronous FPGA architecture that is capable of implementing relative timing based asynchronous designs. The architecture uses the Xilinx 7-Series architecture as a starting point and proposes modifications that would make it asynchronous design capable while keeping it full... | | 2014-01-01 |

Planelles, Vicente | An HIV-encoded antisense long non-coding RNA epigenetically regulates viral transcription | The abundance of long non-coding RNAs (lncRNAs) and their wide range of functional roles in human cells are fast becoming realized. Importantly, lncRNAs have been identified as epigenetic modulators and consequently play a pivotal role in the regulation of gene expression. A human immunodeficiency v... | | 2014-01-01 |
