As part of the continuing effort to collect baseline information on the environmental occurrence of pharmaceuticals, and other organic wastewater contaminants (OWCs) in the Nation's water resources, water samples were collected from a network of 47 groundwater sites across 18 states in 2000. All samples collected were analyzed for 65 OWCs representing a wide variety of uses and origins. Site se...

The repellent 1-(3-cyclohexen-1-yl-carbonyl)-2-methylpiperidine (AI3-37220) was compared with 2 formulations of diethylmethylbenzamide (deet) for its effectiveness in protecting 4 humans against the bites of Anopheles koliensis mosquitoes at a village in Central Province, Papua New Guinea. A mean of 77.2 +/- 10.5 bites/human/10 min of An. koliensis was collected on ethanol-treated (control) vol...

How polysyllabic English words are analyzed in silent reading was examined in three experiments by comparing lexical decision responses to words physically split on the screen. The gap was compatible either with the Maximal Onset Principle or the Maximal Coda Principle. The former corresponds to the spoken syllable (e.g., ca det), except when the word has a stressed short first vowel (e.g., ra ...

The space of Monge-Ampère functions, introduced by J. H. G. Fu in [7, 8] is a space of rather rough functions in which the map u 7→ Det D is well-defined and weakly continuous with respect to a natural notion of weak convergence. We prove a rigidity theorem for Lagrangian integral currents that allows us to extend the original definition of Monge-Ampère functions given in [7]. We also prove tha...

Abstract We review several determinant and Pfaffian identities, which generalize the evaluation formulae of Cauchy’s determinant det (1/(xi + yj)) and Schur’s Pfaffian Pf ((xj − xi)/(xj + xi)). As a multi-variable generalization, we consider Cauchytype determinants and Schur-type Pfaffians of matrices with entries involving some generalized Vandermonde determinants. Also we give an elliptic gen...

Kohn has proved that the Bergman projection associated to a smooth bounded domain D maps C°°(D) into C°°(D) when D is strictly pseudoconvex [11], and more generally, when the boundary of D satisfies certain geometric conditions [12]. Diederich and Fornaess [6] have shown that these conditions are satisfied when the boundary of D is real analytic and pseudoconvex. REMARKS. (A) Our proof of Theor...

In this paper we consider some problems in the Arakelov geometry of Mg, the moduli space of smooth projective curves of genus g over C. Specifically, we are interested in naturally metrized line bundles over Mg and their extensions to Mg, the Deligne-Mumford compactification of Mg. These line bundles typically occur when computing the archimedean height of a curve. Here they arise in computatio...

In an earlier paper 1] two of us studied generalized transfer operators M associated to maps of intervals of R. In particular the analyticity of a sharp determinant Det # (1?zM) was analyzed on the basis of spectral properties of M and by relating Det # (1 ? zM) to the determinant of 1 + D(z) for a suitable kneading operator D(z). It is a natural idea to try to replace monotone maps of interval...

We discuss properties of a generalized Minkowski-Funk transform de…ned for a family of hypersurfaces. We prove two-side estimates for the integral operator and show that the range conditions can be written in terms of the reciprocal Funk transform. Some applications to the spherical mean transform are considered. 1 Families of hypersurfaces Let X and be smooth manifolds of dimension n > 1 and F...

A switching mechanism in gene expression, where two genes are positively correlated in one condition and negatively correlated in the other condition, is a key to elucidating complex biological systems. There already exist methods for detecting switching mechanisms from microarrays. However, current approaches have problems under three real cases: outliers, expression values with a very small r...
