Modeling Electric Fields in Support of a Measurement of the Neutron Electric Dipole Moment

This research focuses on calculating electric fields in support of a proposed experiment to measure the electric dipole moment (EDM) of the neutron at Las Alamos National Laboratory. The experiment will employ a very strong electric field to exert a torque on the neutrons EDM, if any exists. Field Precision software is used to calculate the theoretical electric fields in and around the central detector region of the proposed experimental setup. This research has two goals. The first is to seek out areas of high electric field in the apparatus that will cause arcing and disrupt the experiment. When these areas are found, the shapes of parts are changed to eliminate the problem. The second goal is to map the electric field in the central detector region where measurements are to be made. It is desirable to know the strength, direction, and uniformity of the electric field in this region. The results of this research will be crucial to the design and execution of the proposed experiment to measure the neutrons EDM, which will, in turn, have far reaching implications in theoretical particle physics

Modernization of EC Competition Law: Reform of Regulation No. 17

Ladies and Gentlemen, at last year\u27s conference I presented to you a wide variety of ongoing and proposed reforms with which the European Union intends to meet actual and future challenges for its competition policy. Today, one year later, we have made considerable progress in many respects. Most importantly, with our White Paper of 28 April 1999, we have launched the process for a fundamental reform of the rules implementing Articles 81 and 82 of the Treaty establishing the European Community (‘EC Treaty‘), which are currently laid down in Council Regulation No. 17. Anticipating your expectations and my fellow panelists\u27 contributions, I will today concentrate on the reform of Regulation No. 17

The Effect of Strong Electrostatic and Magnetostatic Fields on the Activity of Radioactive Nuclides

This experiment seeks to measure the effect of strong electrostatic and magnetostatic fields on the decay constant of short-lived radioactive isotopes. Though it is assumed in modern radioactivity theory that such fields should not have any measurable effect, conclusive evidence utilizing modern equipment is absent from published literature. Samples have been monitored that exhibit beta-minus, beta-plus, electron capture, and internal conversion modes of radioactive decay. Radioactive nuclides chosen for this study include I-128, Cs-134, and Cu-64. The half-lives in this collection of radioactive nuclides range from 25 minutes to 12.7 hours. Sodium Iodide detectors are used to monitor the samples both before and after they are placed in a strong static electric or magnetic field. Electric fields used in this study are about 20kV/cm and magnetic fields are inhomogeneous between 4.5kGauss and 7.5kGauss. From the data collected, the half-life of the sample during the time in the field is calculated, and this is compared to the normal half-life in the absence of strong electric or magnetic fields. This experiment is looking for very small deviations in the half-lives that escaped detection in earlier experiments that used cruder equipment

Country and Industry-Level Performance of NASDAQ-Listed European and Asia Pacific ADRs

This study examines the 3-year performance of NASDAQ-Listed Asia Pacific and European ADRs versus the NASDAQ Index and their respective regional indexes from 1990-2010. Country specific performance results show ADRs from China, Japan and Ireland performed best versus the US and regional benchmarks. Industry-level results show the best industry performers were in the Technology Hardware & Services industry and in Energy companies

Flow Smoothing and Denoising: Graph Signal Processing in the Edge-Space

This paper focuses on devising graph signal processing tools for the treatment of data defined on the edges of a graph. We first show that conventional tools from graph signal processing may not be suitable for the analysis of such signals. More specifically, we discuss how the underlying notion of a `smooth signal' inherited from (the typically considered variants of) the graph Laplacian are not suitable when dealing with edge signals that encode a notion of flow. To overcome this limitation we introduce a class of filters based on the Edge-Laplacian, a special case of the Hodge-Laplacian for simplicial complexes of order one. We demonstrate how this Edge-Laplacian leads to low-pass filters that enforce (approximate) flow-conservation in the processed signals. Moreover, we show how these new filters can be combined with more classical Laplacian-based processing methods on the line-graph. Finally, we illustrate the developed tools by denoising synthetic traffic flows on the London street network.Comment: 5 pages, 2 figur
