• (1996-08)
During the ten years from 1967 to 1977 that Francis Xavier Nnaggenda lived outside his native Uganda, he produced a series of paintings that represent more than a literal crossing of lines. Rather, this series crosses ...
• (2000-12)
Tucked away in the northernmost district of Mongolia is a small group of approximately thirty reindeer-herding families who call themselves the Dukha. For centuries unknown to the Western world, the history and culture of ...
• (American Physical Society, 2015)
The potential of precision spectroscopy as a tool in systematic searches for effects of Lorentz and $\text{CPT}$ violation is investigated. Systems considered include hydrogen, antihydrogen, deuterium, positronium, and ...
• (American Physical Society, 2016)
The prospects are explored for testing Lorentz and $\text{CPT}$ symmetry in the top-quark sector. We present the relevant Lagrange density, discuss physical observables, and describe the signals to be sought in experiments. ...
• (American Physical Society, 2000)
Experiments using macroscopic samples of spin-polarized matter offer exceptional sensitivity to Lorentz and $CPT$ violation in the electron sector. Data from existing experiments with a spin-polarized torsion pendulum ...
• (American Physical Society, 2004)
We consider neutrino oscillations in the minimal Standard-Model Extension describing general Lorentz and $CPT$ violation. Among the models without neutrino mass differences is one with two degrees of freedom that reproduces ...
• (American Physical Society, 2004)
A general formalism is presented for violations of Lorentz and $CPT$ symmetry in the neutrino sector. The effective Hamiltonian for neutrino propagation in the presence of Lorentz and $CPT$ violation is derived, and its ...
• (American Physical Society, 2004)
A general discussion is given of signals for broken Lorentz symmetry in short-baseline neutrino experiments. Among the effects that Lorentz violation can introduce are a dependence on energy differing from that of the usual ...
• (American Physical Society, 2010)
Field theories with spontaneous Lorentz violation involving an antisymmetric 2-tensor are studied. A general action including nonminimal gravitational couplings is constructed, and features of the Nambu-Goldstone and massive ...
• (American Physical Society, 2012)
A class of calculable global models for neutrino oscillations based on Lorentz and $CPT$ violation is presented. One simple example matches established neutrino data from accelerator, atmospheric, reactor, and solar ...
• (American Physical Society, 2007)
Possible Lorentz-violating effects in the cosmic microwave background are studied. We provide a systematic classification of renormalizable and nonrenormalizable operators for Lorentz violation in electrodynamics and use ...
• (American Physical Society, 2004)
The static limit of Lorentz-violating electrodynamics in vacuum and in media is investigated. Features of the general solutions include the need for unconventional boundary conditions and the mixing of electrostatic and ...
• (American Physical Society, 1998)
In the context of conventional quantum field theory, we present a general Lorentz-violating extension of the minimal SU(3)×SU(2)×U(1) standard model including $CPT$-even and $CPT$-odd terms. It can be viewed as the low-energy ...
• (American Physical Society, 1987)
A Lorentzian algebra is constructed that underlies the covariant formulation of the spinning string. It is a simply laced hyperbolic Kac-Moody algebra having a realization on the ghost-extended spectrum of string states. ...

Low tone raising (LTR) refers to a phonological rule postulated for Hausa by Leben [1971], whereby word-final Low-Low sequences change to Low-High if the final vowel is long. In the first part of the paper, we show ...
