3-D Finite Element Analysis of Induction Logging in a Dipping Formation (open access)

3-D Finite Element Analysis of Induction Logging in a Dipping Formation

Electromagnetic induction by a magnetic dipole located above a dipping interface is of relevance to the petroleum well-logging industry. The problem is fully three-dimensional (3-D) when formulated as above, but reduces to an analytically tractable one-dimensional (1-D) problem when cast as a small tilted coil above a horizontal interface. The two problems are related by a simple coordinate rotation. An examination of the induced eddy currents and the electric charge accumulation at the interface help to explain the inductive and polarization effects commonly observed in induction logs from dipping geological formations. The equivalence between the 1-D and 3-D formulations of the problem enables the validation of a previously published finite element solver for 3-D controlled-source electromagnetic induction.

3-D TECATE/BREW: Thermal, stress, and birefringent ray-tracing codes for solid-state laser design

This report describes the physics, code formulations, and numerics that are used in the TECATE (totally Eulerian code for anisotropic thermo-elasticity) and BREW (birefringent ray-tracing of electromagnetic waves) codes for laser design. These codes resolve thermal, stress, and birefringent optical effects in 3-D stationary solid-state systems. This suite of three constituent codes is a package referred to as LASRPAK.

[2004 Board Member Calls for Dues] (open access)

[2004 Board Member Calls for Dues]

A 2004 Board Member call for dues to be paid by Texas Daily Newspaper Association members. The document is sub-divided into three sections, "Delinquent Dues," "Dropped," and "Paid." Delinquent dues are newspapers who owe the association money, and dropped are the newspaper who are no longer part of the association because they never paid the due amount.

Plane crash near some trees and a creek. The plane is mostly intact with little damage. Photo taken in the daytime. Photograph taken for a newspaper owned by the Oklahoma Publishing Company. Caption: "VACATION ENDED for members of the Ray Lynch family, 2115 NW 20, when their plane overshot the runway at Expressway Junction Airport, 3101 NE 63 and crashed in a creek bed Saturday noon. Mrs. Lynch received pulled pack muscles, but Lynch and their three children escaped injury. The family was returning from a vacation at Yellowstone National Park."

2012 ATOMIC AND MOLECULAR INTERACTIONS GORDON RESEARCH CONFERENCE AND GORDON RESEARCH SEMINAR, JULY 15-20, 2012 (open access)

2012 ATOMIC AND MOLECULAR INTERACTIONS GORDON RESEARCH CONFERENCE AND GORDON RESEARCH SEMINAR, JULY 15-20, 2012

At the 2012 Atomic and Molecular Interactions Gordon Conference, there will be talks in several broadly defined and partially overlapping areas:  Intramolecular and single-collision reaction dynamics;  Photophysics and photochemistry of excited states;  Clusters, aerosols and solvation;  Interactions at interfaces;  Conformations and folding of large molecules;  Interactions under extreme conditions of temperature and pressure. The theme of the Gordon Research Seminar on Atomic & Molecular Interactions, in keeping with the tradition of the Atomic and Molecular Interactions Gordon Research Conference, is far-reaching and involves fundamental research in the gas and condensed phases along with application of these ideas to practical chemical fields. The oral presentations, which will contain a combination of both experiment and theory, will focus on four broad categories:  Ultrafast Phenomena;  Excited States, Photoelectrons, and Photoions;  Chemical Reaction Dynamics;  Biomolecules and Clusters.

2012 PLANT MOLECULAR BIOLOGY GORDON RESEARCH CONFERENCE, JULY 15-20, 2012 (open access)

2012 PLANT MOLECULAR BIOLOGY GORDON RESEARCH CONFERENCE, JULY 15-20, 2012

The 2012 Gordon Conference on Plant Molecular Biology will present cutting-edge research on molecular aspects of plant growth and development, with particular emphasis on recent discoveries in molecular mechanisms involved with plant signaling systems. The Conference will feature a wide range of topics in plant molecular biology including hormone receptors and early events in hormone signaling, plant perception of and response to plant pathogen and symbionts, as well as technological and biological aspects of epigenomics particularly as it relates to signaling systems that regulate plant growth and development. Genomic approaches to plant signaling will be emphasized, including genomic profiling technologies for quantifying various biological subsystems, such as the epigenome, transcriptome, phosphorylome, and metabolome. The meeting will include an important session devoted to answering the question, "What are the biological and technological limits of plant breeding/genetics, and how can they be solved"?

Ab-Initio Step- and Kink-Formation Energies on Pb(111) (open access)

Ab-Initio Step- and Kink-Formation Energies on Pb(111)

Ab-initio formation energies for (100)- and (111)-microfacet steps on Pb(111) are in satisfactory agreement with measured values, given that these values are known only as well as the Pb(111) surface energy; the calculated step-energy ratio, 1.29, is within {approximately}8% of experiment. In contrast, calculated kink-formation energies, 41 and 60 meV for the two step types, are 40--50% below published experimental values derived from STM images. The discrepancy results from interpreting the images with a step-stiffness vs. kink-energy relation appropriate to (100) but not (111) surfaces. Good agreement is found when the step-stiffness data are reinterpreted, taking proper account of the trigonal symmetry of Pb(111).
