Unintentional recruiting for diversity.
(Public Libraries, 2005)
Based on interviews with Latino undergraduate students, Latino and Native American graduate students in library and information science, and Latino librarians, this paper documents some techniques librarians unintentionally ...

Proyecto de investigaciones arqueológicas en Buena Vista, Valle del Chillón
Las excavaciones en el sitio Precerámico de Paloma, Valle de Chilca (Engel 1980; Benfer 1982, 1990, 1999) y otros (Weir, Benfer, and Jones 1987; Pechenkina et al. 2006) han aportado importantes datos del período Precerámico ...
Compositions with the Euler and Carmichael Functions
(Springer Verlag, 2005)
Let ' and _ be the Euler and Carmichael functions, respectively. In this paper, we establish lower and upper bounds for the number of positive integers n ≤ x such that '(_(n)) = _('(n)). We also study the normal order of ...
Lowpass Filtering of Rate-Distortion Functions for Quality Smoothing in Real-Time Video Communication
In variable-bit-rate (VBR) video coding, the video is pre-processed to collect sequence-level statistics, which are used for global bit allocation in the actual encoding stage to obtain a smoothed video presentation ...
Accurate 3D Tracking of Rigid Objects with Occlusion Using Active Appearance Models
In this paper we present a new method for tracking rigid objects using a modified version of the Active Appearance Model. Unlike most of the other appearance-based methods in the literature, such as [3,5,6,9,11], our ...
For a Sustainable Agriculture, We Need More Adam Smith, Not Less
There are two competing approaches to sustainability in agriculture. One stresses a strict economic approach in which market forces should be allowed to guide the activities of agricultural producers. The other advocates ...
Values of Arithmetical Functions Equal to a Sum of Two Squares
(Oxford University Press, 2005)
Let '(n) denote the Euler function. In this paper, we determine the order of growth for the number of positive integers n ≤ x for which '(n) is the sum of two square numbers. We also obtain similar results for the Dedekind ...
Irrationality of Power Series for Various Number Theoretic Functions
We study formal power series whose coefficients are taken to be a variety of number theoretic functions, such as the Euler, Möbius and divisor functions. We show that these power series are irrational over ℤ [X], and we ...
On the Value Set of n! Modulo a Prime
We show that for infinitely many prime numbers p there are at least log log p/ log log log p distinct residue classes modulo p that are not congruent to n! for any integer n.
A Mission to Explore the Pioneer Anomaly
The Pioneer 10 and 11 spacecraft yielded the most precise navigation in deep space to date. These spacecraft had exceptional acceleration sensitivity. However, analysis of their radio-metric tracking data has consistently ...
Quantum Theory in Accelerated Frames of Reference
The observational basis of quantum theory in accelerated systems is studied. The extension of Lorentz invariance to accelerated systems via the hypothesis of locality is discussed and the limitations of this hypothesis are ...
Tidal acceleration of ultrarelativistic particles
(EDP Sciences, 2005)
We investigate the motion of free relativistic particles relative to the ambient medium around a gravitationally collapsed system. If the relative speed exceeds a critical value given by c/√2, the gravitational tidal ...
Spinning particles in the vacuum C metric
(Institute of Physics, 2005)
The motion of a spinning test particle given by the Mathisson-Papapetrou equations is studied on an exterior vacuum C metric background spacetime describing the accelerated motion of a spherically symmetric gravitational ...
