What Are They Learning: a Study of Errors Produced During Behavior Acquisition Utilizing Two Prompting Procedures with a Cat
Prompting methods are common amongst animal trainers, both novice and experts. However, there is little empirical evidence to demonstrate the strengths or weaknesses of common prompting procedures. The current study assessed the strengths and weaknesses during behavior acquisition of two prompting methods, luring and targeting. Luring placed an edible directly in front of the animal which guided the animal through the desired behavior. Targeting, however used a target, an arbitrary object the animal has been trained to touch, guide behavior. A cat was trained, using each method, to walk around a flower. Walking around the right flower pot was trained using luring and walking around the left flower pot was trained using targeting. After both behaviors were acquired, a delay cue method was designed to transfer stimulus control. Later a combination of a delay cue and prompt fading was used. During acquisition the luring method acquired the behavior of walking around a pot more quickly with consistently fewer errors. During stimulus transfer the cat began independently initiating the behavior earlier with the target trained behavior and produced more correct behaviors after the verbal cue. Luring appeared to produce the faster behavior, but after stimulus transfer it could be concluded that …

Multi-perspective, Multi-modal Image Registration and Fusion
Multi-modal image fusion is an active research area with many civilian and military applications. Fusion is defined as strategic combination of information collected by various sensors from different locations or different types in order to obtain a better understanding of an observed scene or situation. Fusion of multi-modal images cannot be completed unless these two modalities are spatially aligned. In this research, I consider two important problems. Multi-modal, multi-perspective image registration and decision level fusion of multi-modal images. In particular, LiDAR and visual imagery. Multi-modal image registration is a difficult task due to the different semantic interpretation of features extracted from each modality. This problem is decoupled into three sub-problems. The first step is identification and extraction of common features. The second step is the determination of corresponding points. The third step consists of determining the registration transformation parameters. Traditional registration methods use low level features such as lines and corners. Using these features require an extensive optimization search in order to determine the corresponding points. Many methods use global positioning systems (GPS), and a calibrated camera in order to obtain an initial estimate of the camera parameters. The advantages of our work over the previous works are the following. …

International Experiences and Frameworks to Support Country-Driven Low-Emissions Development
Countries can use low-emission development strategies (LEDS) to advance sustainable development, promote private-sector growth, and reduce greenhouse gas emissions. This paper proposes a framework -- or support infrastructure -- to enable the efficient exchange of LEDS-related knowledge and technical assistance. Under the proposed framework, countries share LEDS-related resources via coordinating forums, 'knowledge platforms,' and networks of experts and investors. The virtual 'knowledge platforms' foster learning by allowing countries to communicate with each other and share technical reports, data, and analysis tools in support of LEDS development. Investing in all elements of the framework in an integrated fashion increases the efficacy of support for country-driven LEDS.

The Effects of the Scattering by Edge Plasma Density Fluctuations on Lower Hyybrid Wave Propagation
Scattering effects induced by edge density fluctuations on lower hybrid (LH) wave propagation are investigated. The scattering model used here is based on the work of Bonoli and Ott [Phys. Fluids 25 (1982) 361]. It utilizes an electromagnetic wave kinetic equation solved by a Monte Carlo technique. This scattering model has been implemented in GENRAY , a ray tracing code which explicitly simulates wave propagation, as well as collisionless and collisional damping processes, over the entire plasma discharge, including the scrape-off layer (SOL) that extends from the separatrix to the vessel wall. A numerical analysis of the LH wave trajectories and the power deposition profile with and without scattering is presented for Alcator CMod discharges. Comparisons between the measured hard x-ray emission on Alcator C-Mod and simulations of the data obtained from the synthetic diagnostic included in the GENRAY/CQL3D package are shown, with and without the combination of scattering and collisional damping. Implications of these results on LH current drive are discussed.

A New Scheme for Stigmatic X-ray Imaging with Large Magnification
This paper describes a new x-ray scheme for stigmatic imaging. The scheme consists of one convex spherically bent crystal and one concave spherically bent crystal. The radii of curvature and Bragg reflecting lattice planes of the two crystals are properly matched to eliminate the astigmatism, so that the conditions for stigmatic imaging are met for a particular wavelength. The magnification is adjustable and solely a function of the two Bragg angles or angles of incidence. Although the choice of Bragg angles is constrained by the availability of crystals, this is not a severe limitation for the imaging of plasmas, since a particular wavelength can be selected from the bremsstrahlung continuum. The working principle of this imaging scheme has been verified with visible light. Further tests with x rays are planned for the near future. 2012 American Institute of Physics

A Summary of Fault Recurrence and Strain Rates in the Vicinity of the Hanford Site--Topical Report
This document is one in a series of topical reports compiled by the Pacific Northwest National Laboratory to summarize technical information on selected topics important to the performance of a probabilistic seismic hazard analysis of the Hanford Site. The purpose of this report is to summarize available data and analyses relevant to fault recurrence and strain rates within the Yakima Fold Belt. Strain rates have met with contention in the expert community and may have a significant potential for impact on the seismic hazard estimate at the Hanford Site. This report identifies the alternative conceptual models relevant to this technical issue and the arguments and data that support those models. It provides a brief description of the technical issue and principal uncertainties; a general overview on the nature of the technical issue, along with alternative conceptual models, supporting arguments and information, and uncertainties; and finally, suggests some prospective approaches to reducing uncertainties about earthquake recurrence rates for the Yakima Fold Belt.

Between Comancheros and Comanchería: a History of Fort Bascom, New Mexico
In 1863, Fort Bascom was built along the Canadian River in the Eroded Plains of Territorial New Mexico. Its unique location placed it between the Comanches of Texas and the Comancheros of the Sangre de Cristo Mountains. This post was situated within Comanchería during the height of the United States Army's war against the Southern Plains Indians, yet it has garnered little attention. This study broadens the scholarly understanding of how the United States Army gained control of the Southwest by examining the role Fort Bascom played in this mission. This includes an exploration of the Canadian River Valley environment, an examination of the economic relationship that existed between the Southern Plains Indians and the mountain people of New Mexico, and an account of the daily life of soldiers posted to Fort Bascom. This dissertation thus provides an environmental and cultural history of the Canadian River Valley in New Mexico, a social history of the men stationed at Fort Bascom, and proof that the post played a key role in the Army's efforts to gain control of the Southern Plains Indians. This study argues that Fort Bascom should be recognized as Texas' northern-most frontier fort. Its men were closer to …

Libya: Transition and U.S. Policy
This report discusses the revolution and post-conflict transition in Libya. The crisis was triggered in mid-February 2011 by a chain of events in Benghazi and other eastern cities that quickly spiraled out of Qadhafi's control and resulted in his death. A July election marked a shift from the appointed interim government and may provide more democratic legitimacy and better decision making. The report also looks at the military and economic state of the country, including human rights, Islam and politics, and Libya's oil asses.

A Comparison of Image Quality Evaluation Techniques for Transmission X-Ray Microscopy
Beamline 6-2c at Stanford Synchrotron Radiation Lightsource (SSRL) is capable of Transmission X-ray Microscopy (TXM) at 30 nm resolution. Raw images from the microscope must undergo extensive image processing before publication. Since typical data sets normally contain thousands of images, it is necessary to automate the image processing workflow as much as possible, particularly for the aligning and averaging of similar images. Currently we align images using the 'phase correlation' algorithm, which calculates the relative offset of two images by multiplying them in the frequency domain. For images containing high frequency noise, this algorithm will align noise with noise, resulting in a blurry average. To remedy this we multiply the images by a Gaussian function in the frequency domain, so that the algorithm ignores the high frequency noise while properly aligning the features of interest (FOI). The shape of the Gaussian is manually tuned by the user until the resulting average image is sharpest. To automatically optimize this process, it is necessary for the computer to evaluate the quality of the average image by quantifying its sharpness. In our research we explored two image sharpness metrics, the variance method and the frequency threshold method. The variance method uses the variance …

U.S. Foreign-Trade Zones: Background and Issues for Congress
Members of Congress have demonstrated their interest in the U.S. Foreign-Trade Zone (FTZ) system through hearings and legislation over the past seven decades. The program may enhance the competitiveness of U.S. businesses, support employment opportunities, and impact U.S. tariff revenues. Balancing these potential gains, others argue that the program may also be trade distorting, and may play a role in misallocating resources in the economy as a whole. This report provides a general perspective on the U.S. FTZ system. It is divided into three parts. As background, the first section discusses free trade zones worldwide. The second section focuses on the U.S. FTZ program—its history, administrative mechanism, structure, growth and industry concentration, and benefits and costs. The third section focuses on current issues for Congress relating to the U.S. FTZ program.

High-temperature treatment of In-doped CZT crystals grown by the high-pressure Bridgman method
We evaluated the effect of high-temperature treatment of Cd0.9Zn0.1Te:In single crystals using Hall-effect measurements, medium- and high-temperature annealing under various deviations from stoichiometry, and infra-red (IR) transmission microscopy Annealing at ~730 K sharply increased the electrical conductivity (by ~1-2 orders-of-magnitude). Plots of the temperature- and cadmium-pressure dependences of the electrical conductivity, carrier concentration, and mobility were obtained. Treating previously annealed Cd-samples under a Te overpressure at 1070 K allowed us to restore their resistance to its initial high values. The main difference in comparing this material with CdTe was its lowered electron density. We explained our results within the framework of Kröger’s theory of quasi-chemical reactions between point defects in solids.
