Charge assignments in multiple-U(1) gauge theories

Estimate Of The Incoherent-Scattering Contribution To Lidar Backscatter From Clouds
(Optical Society of America, 1999-09-01)
Lidar backscatter from clouds in the Delft University of Technology experiment is complicated by the fact that the transmitter has a narrow beam width, whereas the receiver has a much wider one. The issue here is whether ...
Exact results for the Kardar-Parisi-Zhang equation with spatially correlated noise
Residential buildings and the cost of construction: new evidence on the efficiency of the housing market
(MIT Press, 1999-05)
Present value studies of asset market efficiency are controversial because they compare asset prices to unobserved discounted streams of future rents. As an alternative, if housing markets are efficient, then the price of ...
Photogeneration action spectroscopy of neutral and charged excitations in films of a ladder-type poly(para-phenylene)
(American Physical Society, 1999-04-19)
The photogeneration quantum efficiency action spectra of long-lived neutral and charged excitations in films of a ladder-type poly(para-phenylene) were measured. We found that both tripler and polaron action spectra show, ...
Photogeneration and recombination processes of neutral and charged excitations in films of a ladder-type poly(para-phenylene)
(American Physical Society, 1999-08-15)
We introduce a version of the cw photomodulation technique, measured far from the steady state, for obtaining the quantum efficiency, eta, of long-lived photoexcitations in pi-conjugated polymers. We apply this technique ...
Critical dynamics at incommensurate phase transitions and NMR relaxation experiments
(American Physical Society, 1999-05)
We study the critical dynamics of crystals which undergo a second-order phase transition from a high-temperature normal phase to a structurally incommensurate (IC) modulated phase. We give a comprehensive description of ...
14-year program monitoring the flux densities of 33 radio sources at low frequencies
(IOP PUBLISHING LTD, 1999-01)
We present the results of a low-frequency flux density monitoring program of 33 extragalactic radio sources. The light curves at 318 and 430 MHz over a 14 yr period are presented. The measurements were made with the NAIC ...
Dependence of fluorescence lifetimes of Y2O3 : Eu3+ nanoparticles on the surrounding medium
(American Physical Society, 1999-11)
The radiative lifetime, tau(R), of the D-5(0) metastable excited state of Eu3+ ions in nanocrystalline monoclinic Y2O3 samples is about four times longer than that in the micron size powder of the same material. The Eu3+ ...
Property tax capitalization in a model with tax-deferred assets, standard deductions, and the taxation of nominal interest
(MIT Press, 1999-02)
Previous property tax capitalization studies assume that families itemize, that they save in taxable assets, and that real interest income is taxed. However, many families do not itemize, many families invest in tax-deferred ...
