#### 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

(Hindawi, 1992-01-01)

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 ...
