#### Developing a field of landscape ecotoxicology

(Ecological Society of America, 1996-08)

Since toxicants are spread over ecological landscapes, it seems likely that they have effects at that level of ecological organization. Landscape ecotoxicology examines the effects of toxic chemicals on larger scales than ...

#### The Contribution Of Galactic Free-Free Emission to Anisotropies in the Cosmic Microwave Background Found by the Saskatoon Experiment

(IOP PUBLISHING LTD, 1996-02)

We made a sensitive, wide-field Ha image of the north celestial polar region. Using this image, we constrain the contribution of irregularities in interstellar free-free emission to the degree-scale anisotropies in the ...

#### Choice of dispersion relation to calculate the QCD correction to Gamma(H->l(+)l(-))

(American Physical Soc, 1996-02-01)

We use the Operator Product Expansion (OPE) of quark vacuum polarization functions to show that the dispersion relation of Kniehl and Sirlin will yield the correct result to all orders in αs when applied to the QCD correction ...

#### factorization of scattering matrices due to partitioning of potentials in one-dimensional Schrodinger-type equations

(AIP Publishing, 1996-12)

The one-dimensional Schrodinger equation and two of its generalizations are considered, as they arise in quantum mechanics, wave propagation in a nonhomogeneous medium, and wave propagation in a nonconservative medium where ...

#### Integral equation methods for the inverse problem with discontinuous wave speed

(AIP Publishing, 1996-07)

The recovery of the coefficient H(x) in the one-dimensional generalized Schrodinger equation d(2) psi dx(2)+k(2)H(x)(2) psi=Q(x)psi, where H(x) is a positive, piecewise continuous function with positive limits H-+/- as ...

#### Variational study of the spin-gap phase of the one-dimensional t-J model

(American Physical Society, 1996-10-01)

We propose a correlated spin-singlet-pair wave function to describe the spin-gap phase of the one-dimensional t-J model at low density and large J/t. In addition to having singlet pairs, this wave function has a Jastrow ...

#### Indirect probes of new physics

(World Scientific, 1996)

We summarize the indirect effects of new physics in a variety of processes. We consider precision electroweak measurements, the g−2 of the muon, rare decays, meson mixing, CP violation, lepton number violating interactions, ...

#### linear stability analysis of salt fingers with surface evaporation or warming

(AIP Publishing, 1996-11)

Oceanic observations [Atmos. Ocean 29, 340 (1991)] have revealed small-scale thermohaline plumes near the surface of a calm sea under warming conditions. The stratification was favorable for the double-diffusive salt finger ...

#### internal capillary-gravity waves of a two-layer fluid with free surface over an obstruction - Forced extended KdV equation

(AIP Publishing, 1996-02)

In this paper we study steady capillary-gravity waves in a two-layer fluid bounded above by a free surface and below by a horizontal rigid boundary with a small obstruction. Two critical speeds for the waves are obtained. ...

#### Interferometric Model For Phase Analysis in Fiber Couplers

(Optical Society of America, 1996-07-01)

An interferometric model is proposed to estimate the phase differences in lossless, strongly coupled biconical fiber couplers. This approximate method is simpler than the traditional s-parameter network theory-based analysis ...
