R Aquarii: First Detection of Circumstellar SiO Maser Proper Motions
(IOP PUBLISHING LTD, 1997-10)
We have made the first detection of circumstellar SiO maser proper motions in the envelope of a late-type star. Using the Very Long Baseline Array (VLBA), we have obtained observations at four epochs of the 43 GHz, upsilon ...
Constraints on top-color assisted technicolor models from vertex corrections
(American Physical Soc, 1999-07-01)
On a wave equation with a boundary condition associated with capillary waves
(Siam Publications, 1998-09)
This paper discusses an initial-boundary value problem for a wave equation with a nonstandard boundary condition associated with linear capillary waves on the surface of a compressible liquid. We prove the well-posedness ...
Systematic scaling in the low-energy excitations of the t-J model in one and two dimensions
(American Physical Society, 1997-05-01)
We present an exact diagonalization study of the low-energy singlet and triplet states for both the one-dimensional (1D) and 2D t-J models. A scan of the parameter ratio J/t shows that for most low-energy states in both ...
Electron-energy-loss and optical-transmittance investigation of Bi2Sr2CaCu2O8
(American Physical Society, 1990-07)
The energy-loss function Im(-1/ε) of Bi2Sr2CaCu2O8 has been measured over the range Eloss=0.8 to 80 eV by transmission electron-energy-loss spectroscopy (EELS) (nonimaging). The energy and momentum resolution were 0.1 eV ...
Commutative rings with homomorphic power functions
A (commutative) ring R (with identity) is called m-linear (for an integer m≥2) if (a+b)m=am+bm for all a and b in R. The m-linear reduced rings are characterized, with special attention to the finite case. A structure ...
