    This thesis examines the methods used by the Ministerium für Staatssicherheit (MfS), more commonly known as the Stasi, or East German secret police, for extraction of information from citizens of the German Democratic Republic for the purpose of espionage and covert operations inside East Germany, as it pertains to the deliberate brainwashing of East German citizens. As one of the most efficient intelligence agencies to ever exist, the Stasi’s main purpose was to monitor the population, gather intelligence, and collect or turn informants. They used brainwashing techniques to control the people of the GDR, keeping the populace paralyzed with fear and paranoia. By surrounding themselves with a network of informants they prevented actions against the dictatorial communist regime. Using the video testimonies of former prisoners, and former confidential informants who worked closely with and collaborated with Stasi agents, in combination with periodicals and previous historical studies, this work argues that the East German Police State’s brainwashing techniques had long and lasting consequences both for German citizens, and for the psychiatric health of former GDR citizens. The scope and breadth of the techniques and data compiled for use by the Stasi were exhaustive, and the repercussions of their use are still being felt and discovered twenty five years after the fall of the Berlin Wall. This study aims to show the lasting effects brainwashing had on former informants and the Stasi’s victims

    Blocking Filters with Enhanced Throughput for X-Ray Microcalorimetry

    Get PDF
    New and improved blocking filters (see figure) have been developed for microcalorimeters on several mission payloads, made of high-transmission polyimide support mesh, that can replace the nickel mesh used in previous blocking filter flight designs. To realize the resolution and signal sensitivity of today s x-ray microcalorimeters, significant improvements in the blocking filter stack are needed. Using high-transmission polyimide support mesh, it is possible to improve overall throughput on a typical microcalorimeter such as Suzaku s X-ray Spectrometer by 11%, compared to previous flight designs. Using polyimide to replace standard metal mesh means the mesh will be transparent to energies 3 keV and higher. Incorporating polyimide s advantageous strength-to-weight ratio, thermal stability, and transmission characteristics permits thinner filter materials, significantly enhancing through - put. A prototype contamination blocking filter for ASTRO-H has passed QT-level acoustic testing. Resistive traces can also be incorporated to provide decontamination capability to actively restore filter performance in orbit

    Effectiveness of the Surrogator at Increasing Northern Bobwhite Abundance and Enhancing Hunting

    The main objectives of this study were to: (1) quantify in-surrogator survival of bobwhite chicks, (2) monitor post-release survival, habitat use, and dispersal, (3) and record rate at which surrogator bobwhite were harvested. In-surrogator survival was recorded by weekly monitoring the surrogator unit and recording mortality. Post-release data were obtained by attaching transmitters to a sample of surrogator bobwhites and using radiotelemtry to track the birds. Habitat use was measured using the Robel pole, Daubenmire frame, line intercept tape, and cone of vulnerability. Bobwhite harvest information was collected by monitoring hunters during the 2009-2011 bobwhite hunting seasons. In-surrogator bobwhite survival was greater than reported for wild bobwhite chicks, resulting in more birds in the population. Post-release survival of surrogator bobwhites was lower than both wild bobwhites and other captive-release studies. Vegetation surveys at surrogator bobwhite locations revealed similar habitat use as wild bobwhites. Dispersal of surrogator bobwhites off release field was common and resulted in lost recreation to hunters. Surrogator bobwhites did supplement hunter harvest of wild bobwhites by an average of 31% per year, but a huntable population of strictly surrogator bobwhites was not established on the release field by that hunting season. Hunters rated surrogator bobwhites as similar to wild birds. Given these findings it appears surrogator bobwhite survival was too low to sustain a huntable population into the hunting season. Further without the presence of natural bobwhite populations hunter-covey encounters during the 2009-2011 bobwhite hunting seasons would have been rare. Some sportsmen and land managers may find use for the surrogator as a tool to supplement wild populations of bobwhites, though hunter opinion of benefits versus costs will vary.Department of Natural Resource Ecology and Managemen

    Induced quasi-isometries of hyperbolic spaces, Markov chains, and acylindrical hyperbolicity

    Get PDF
    We show that quasi-isometries of (well-behaved) hierarchically hyperbolic groups descend to quasi-isometries of their maximal hyperbolic space. This has two applications, one relating to quasi-isometry invariance of acylindrical hyperbolicity, and the other a linear progress result for Markov chains. The appendix, by Jacob Russell, contains a partial converse under the (necessary) condition that the maximal hyperbolic space is one-ended

    Quantization of Gauge Field Theories on the Front-Form without Gauge Constraints I : The Abelian Case

    Full text link
    Recently, we have proposed a new front-form quantization which treated both the x+x^{+} and the x−x^{-} coordinates as front-form 'times.' This quantization was found to preserve parity explicitly. In this paper we extend this construction to local Abelian gauge fields . We quantize this theory using a method proposed originally by Faddeev and Jackiw . We emphasize here the feature that quantizing along both x+x^+ and x−x^- , gauge theories does not require extra constraints (also known as 'gauge conditions') to determine the solution uniquely.Comment: 18 pages, phyzz

    Sources and Chemistry of NOâ‚“ in the Upper Troposphere Over the United States

    Get PDF
    The origin of NOx in the upper troposphere over the central United States is examined using aircraft observations obtained during the SUCCESS campaign in April–May of 1996. Correlations between NOy (sum of NOx and its oxidation products) and CO at 8–12 km altitude indicate that NOx originates primarily from convective transport of polluted boundary layer air. Lightning and aircraft emissions appear to be only minor sources of NOx. Chemical steady state model calculations constrained by local observations of NO underestimate the measured NOx/NOy concentration ratio at 8–12 km altitude by a factor of two on average. The magnitude of the underestimate is correlated with concentrations of condensation nuclei, which we take as a proxy for the age of air in the upper troposphere. We conclude that the NOx/NOy ratio is maintained above chemical steady state by frequent convective injections of fresh NOx from the polluted boundary layer and by the long lifetime of NOx in the upper troposphere (5–10 days). In contrast to previous studies, we find no evidence for fast heterogeneous recycling from HNO3 to NOx in the upper troposphere

    Boron in copper: a perfect misfit in the bulk and cohesion enhancer at a grain boundary

    Full text link
    Our ab initio study suggests that boron segregation to the Sigma 5(310)[001] grain boundary should strengthen the boundary up to 1.5 ML coverage (15.24 at/nm^2). The maximal effect is observed at 0.5 ML and corresponds to boron atoms filling exclusively grain boundary interstices. In copper bulk, B causes significant distortion both in interstitial and regular lattice sites for which boron atoms are either too big or too small. The distortion is compensated to large extent when the interstitial and substitutional boron combine together to form a strongly bound dumbell. Our prediction is that bound boron impurities should appear in sizable proportion if not dominate in most experimental conditions. A large discrepancy between calculated heats of solution and experimental terminal solubility of B in Cu is found, indicating either a sound failure of the local density approximation or, more likely, strongly overestimated solubility limits in the existing B-Cu phase diagram.Comment: 16 pages, 9 figure

    Mild inborn errors of metabolism in commonly used inbred mouse strains.

    Get PDF
    Inbred mouse strains are a cornerstone of translational research but paradoxically many strains carry mild inborn errors of metabolism. For example, alpha-aminoadipic acidemia and branched-chain ketoacid dehydrogenase deficiency are known in C57BL/6J mice. Using RNA sequencing, we now reveal the causal variants in Dhtkd1 and Bckdhb, and the molecular mechanism underlying these metabolic defects. C57BL/6J mice have decreased Dhtkd1 mRNA expression due to a solitary long terminal repeat (LTR) in intron 4 of Dhtkd1. This LTR harbors an alternate splice donor site leading to a partial splicing defect and as a consequence decreased total and functional Dhtkd1 mRNA, decreased DHTKD1 protein and alpha-aminoadipic acidemia. Similarly, C57BL/6J mice have decreased Bckdhb mRNA expression due to an LTR retrotransposon in intron 1 of Bckdhb. This transposable element encodes an alternative exon 1 causing aberrant splicing, decreased total and functional Bckdhb mRNA and decreased BCKDHB protein. Using a targeted metabolomics screen, we also reveal elevated plasma C5-carnitine in 129 substrains. This biochemical phenotype resembles isovaleric acidemia and is caused by an exonic splice mutation in Ivd leading to partial skipping of exon 10 and IVD protein deficiency. In summary, this study identifies three causal variants underlying mild inborn errors of metabolism in commonly used inbred mouse strains
