Comparison Of Nicarbazin Absorption In Chickens, Mallards, And Canada Geese, C. A. Yoder, L. A. Miller, K. S. Bynum

United States Department of Agriculture Wildlife Services: Staff Publications

Nicarbazin (NCZ), a coccidiostat commonly used in the poultry industry, causes reduced hatchability and egg quality in layer hens at a concentration of 125 ppm (8.4 mg/kg) in the feed. Although this effect is undesirable in the poultry industry, NCZ could provide a useful wildlife contraception tool for waterfowl, particularly urban geese. We tested the absorption of NCZ in chickens (Gallus gallus), mallards (Anas platyrhynchos), and Canada geese (Branta canadensis) gavaged with 8.4 mg of NCZ/kg per bird each day for 8 d. Plasma levels of 4,4'-dinitrocarbanilide (DNC) differed significantly among species. Peak plasma DNC levels were 2.87 f 0.15 …

Blaise Pascal - Mathematician, Mystic, Disciple, Tim Rogalsky

ACMS Conference Proceedings 2005

This is the story of a multi-faceted Christian mathematician. Instrumental in the development of calculus, probability theory, and computing machines, Pascal (1623-1662) was a man equally enamoured with mind and spirit. His conversion experience was marked by both rational decision and mystical vision. He is perhaps best known for "Pascal's wager," which simplistic "fire insurance" version of Christianity, demanding little from the convert. However, a more careful reading of his work and his life reveals that Pascal knew much about discipleship and its cost.

The Five Orders Of Ignorance: Knowledge, Ignorance, And The Nature Of Software, Phillip Armour

ACMS Conference Proceedings 2005

Software is not a product, it is a medium in which we store knowledge. As simple as this idea seems, the consequences of it are quite significant. If software is not a product, then software development is not a product of production activity, despite the common practice of managing it as such. Most organizations believe that job of software developers is to build a system that we then ship to a customer. It is not. The system we build and ship to the customer is actually the by-product of the real activity which is learning. Software development is the activity …

Does The Success Of Mathematics Defeat Naturalism?, Russell W. Howell

ACMS Conference Proceedings 2005

Mathematics As Poesis: A Preliminary Project Report, Sam Stueckle, Jeremy Case, Ken Constantine, Troy Riggs

ACMS Conference Proceedings 2005

This paper talks about the various viewpoints of mathematics, beginning with classical perspectives and ending with the idea of poesis, or the theology of math as the art of making.

Jesus, Plato, Math And Theology: What Is Truth?, Paul Moffett

ACMS Conference Proceedings 2005

Mathematical ontology is relevant to Christians because so much of Christian theology has been historically shaped by Platonic mathematics and the ontology that goes with it. The various contributors to Mathematics in a Postmodern Age, edited by Howell and Bradley, seem to assume that Christians are necessarily realists in ontology, and they are not alone. But what is the cause of this Christian connection with mathematical realism in ontology? How much has our idea of God been shaped by Plato and his mathematics?

The Artificial Gravity Pitch, Andrew Simoson

ACMS Conference Proceedings 2005

Toss a ball into the air; we analyze and contrast the resultant trajectories when standing both on the Little Prince’s Asteroid B-612 of 1943 and in Arthur C. Clark’s rotating space ship Discovery of 2001.

Integrating Catholic And Marianist Historical Perspectives In A Mathematics Coruse For Elementary Education Majors, Mary Wagner-Krankel

ACMS Conference Proceedings 2005

St. Mary's University in San Antonio recently reaffirmed their distinctive nature as a Catholic university promoting the Marianist tradition. This new affirmation is in response to the smaller number of Marianists serving in teaching and administrative positions on campus. Faculty have been encouraged to explore new ways to integrate Catholic and Marianist values and historical perspectives in their teaching and research. I will discuss some major Catholic mathematicians and some classroom activities that I developed for the course MT3304- Mathematics for the Elementary Teacher.

These lessons are appropriate for use at the middle school and high school level.

Explicit Null Space Of Discrete Laplacian, Hanna Vanderzee

ACMS Conference Proceedings 2005

For a given partial differential equation, such as Poisson’s equation in two dimensions, stipulating the null-space component of the solution is sometimes a useful alternative to specifying boundary conditions in order to determine a unique solution. To implement this approach computationally, we need a sparse and well-conditioned representation of the null space of the relevant differential operator. We discuss how the null-space method works and present an explicit formula for generating a sparse null basis for a uniform, finite-difference discretization of Laplacian operator on the unit square. The formula makes use of a triangular array which has the large Schroeder …

Artificial Intelligence: Can We Create Machines In Our Own Image?, Derek C. Shuurman

ACMS Conference Proceedings 2005

The field of Artificial Intelligence (AI) leads to many questions about what it means to be human. Some researchers claim that inevitably computers will reach a certain threshold of complexity that will enable them to “think” and artificial consciousness will emerge. This speculation, taken a step further, leads some to believe that computer technology will eventually set humans free from the frailty of their bodies and enable them to achieve immortality. Underlying these claims is a reductionistic philosophy about what it means to be human and how one approaches the mind-body problem. Ever since the fall people have wanted to …

Kenneth Bloom Publications

We present a measurement of the W⁺W^- production cross section using 184 pb^-1 of pp̅ collisions at a center-of-mass energy of 1.96 TeV collected with the Collider Detector at Fermilab. Using the dilepton decay channel W⁺W^-→ ℓ ⁺ν ℓ ^- ν̅, where the charged leptons can be either electrons or muons, we find 17 candidate events compared to an expected background of 5.0_-0.8^+2.2 events. The resulting W⁺W^- production cross-section measurement of σ (pp̅→W⁺W^-)=14.6_-5.1^+5.8 (stat) _-3.0^+1.8 (syst)±0.9(lum) …

Monomial Nonnegativity And The Bruhat Order, Brian Drake, Sean Gerrish, Mark Skandera

Dartmouth Scholarship

We show that five nonnegativity properties of polynomials coincide when restricted to polynomials of the form x_{1, pi(1)} ... x_n,pi(n) - x_{1, sigma(1)} ... x_{n, sigma(n)}, where $\pi and sigma are permutations in S_n. In particular, we show that each of these properties may be used to characterize the Bruhat order on S_n.

Survey Of Energetic O + Ions Near The Dayside Mid-Latitude Magnetopause With Cluster, M. Bouhram, B. Klecker, G. Paschmann, S. Haaland, H. Hasegawa, A. Blagau, H. Reme, J.A. Sauvaud, L. M. Kistler, A. Balogh

Dartmouth Scholarship

Since December 2000, the Cluster satellites have been conducting detailed measurements of the magnetospheric boundaries and have confirmed the unambiguous presence of ions of terrestrial origin (e.g. O⁺ in regions adjacent to the dayside, mid-latitude magnetopause. In the present paper, we focus on the statistical properties of the O⁺ ion component at energies ranging from 30eV up to 40keV, using three years of ion data at solar maximum from the Cluster Ion Spectrometry (CIS) experiment aboard two Cluster spacecraft. The O⁺ density decreases on average by a factor of 6, from 0.041 to 7x10^-3cm^{-3 …}

Explicit Computations Supporting A Generalization Of Serre's Conjecture, Brian Francis Hansen

Theses and Dissertations

Serre's conjecture on the modularity of Galois representations makes a connection between two-dimensional Galois representations and modular forms. A conjecture by Ash, Doud, and Pollack generalizes Serre's to higher-dimensional Galois representations. In this paper we discuss an explicit computational example supporting the generalized claim. An ambiguity in a calculation within the example is resolved using a method of complex approximation.

Synthesis And Characterization Of Azole Isoflavone Inhibitors Of Aromatase, John C. Hackett, Young Woo Kim, Bin Su, Robert W. Brueggemeier

Chemistry Faculty Publications

The synthesis and biological evaluation of a series of 2-azole and 2-thioazole isoflavones as potential aromatase inhibitors are described. Differences in inhibitory activity of triazole and imidazole inhibitors are rationalized with density functional theory to expose a key difference in the electronic structure of these molecules. In addition, difference binding spectra of inhibitors to immunoaffinity-purified aromatase produces classical Type II spectra consistent with coordination of the nitrogen lone pair electrons to the aromatase P450 heme.

Asserting Cs != Can't Spcialize, Building Community In A Computer Science Program, Kim Kihlstrom

ACMS Conference Proceedings 2005

As humans, we are designed to live in community. "Just as each of us has one body with many members, and these members do not all have the same function, so in Christ we who are many form one body, and each member belongs to all the others" (Romans 12:4-5). We believe it is of critical importance to build community within a computer science program, first of all because it is part of God's calling for us. In addition, building communit allows us to equip students with the interpersonal skills that they need for a productive career, and to attract …

Filtering The Bible And Filtering Spam, Gene B. Chase

ACMS Conference Proceedings 2005

I argue that John Craig (1996?–1731) is the first to do Bayesian statistics. Filtering email spam today using Bayes's analysis of 1763 is a new application of an old theorem. Craig 67 years before Bayes's theorem used subjective probabilities reasoning to argue that Jesus would return in the year 3150, because the Bible would eventually come into disrepute (become spam?) then.

Bibliography Of Christianity And Mathematics, Gene B. Chase

ACMS Conference Proceedings 2005

The invited address provides historiographic background for the second edition of Bibliography of Christianity and Mathematics. The second edition builds on the first edition written jointly with Calvin Jongsma, on the historiographic work of Ivor Grattan-Guiness, and on the computer skills of Gregory Ross.

On-Line Metasearch, Pooling, And System Evaluation, Robert A. Savell

Dartmouth College Ph.D Dissertations

This thesis presents a unified method for simultaneous solution of three problems in Information Retrieval--- metasearch (the fusion of ranked lists returned by retrieval systems to elicit improved performance), efficient system evaluation (the accurate evaluation of retrieval systems with small numbers of relevance judgements), and pooling or ``active sample selection" (the selection of documents for manual judgement in order to develop sample pools of high precision or pools suitable for assessing system quality). The thesis establishes a unified theoretical framework for addressing these three problems and naturally generalizes their solution to the on-line context by incorporating feedback in the form …

The Thermodynamics And Statistical Mechanics Of Protein Folding, Prem P. Chapagain

FIU Electronic Theses and Dissertations

The physics of self-organization and complexity is manifested on a variety of biological scales, from large ecosystems to the molecular level. Protein molecules exhibit characteristics of complex systems in terms of their structure, dynamics, and function. Proteins have the extraordinary ability to fold to a specific functional three-dimensional shape, starting from a random coil, in a biologically relevant time. How they accomplish this is one of the secrets of life. In this work, theoretical research into understanding this remarkable behavior is discussed. Thermodynamic and statistical mechanical tools are used in order to investigate the protein folding dynamics and stability. Theoretical …

Lower Bounds On The Communication Complexity Of Shifting, Marco D. Adelfio

Dartmouth College Undergraduate Theses

We study the communication complexity of the SHIFT (equivalently, SUM-INDEX) function in a 3-party simultaneous message model. Alice and Bob share an n-bit string x and Alice holds an index i and Bob an index j. They must send messages to a referee who knows only n, i and j, enabling him to determine x[(i+j) mod n]. Surprisingly, it is possible to achieve nontrivial savings even with such a strong restriction: Bob can now make do with only ceil(n/2) bits. Here we show that this bound is completely tight, for all n. This is an exact lower bound, with no …

Commutation Relations For Functions Of Operators, Mark K. Transtrum, Jean-Francois S. Van Huele

Faculty Publications

We derive an expression for the commutator of functions of operators with constant commutations relations in terms of the partial derivatives of these functions. This result extends the well-known commutation relation between one operator and a function of another operator. We discuss the range of applicability of the formula with examples in quantum mechanics

Concurrent Markup Hierarchies: A Computer Science Approach, Ionut E. Iacob, Alex Dekhtyar

Computer Science and Software Engineering

It is known that text has not, in general, a regular structure. However, since its invention and despite to the fact that it represents hierarchical structures, XML has gained a lot of popularity among humanities researchers: XML is easy to use and it comes with a handful of free processing tools. A variety of solutions were proposed to represent overlapping structures in XML. More or less easy to maintain from the point of view of data management, none of these solutions provides full support for two of the most demanded processing tasks: querying and presentation (XSL-like transformation).

We propose a …
