Back-Pay Issues in the Military: O\u27Callahan v. United States

Recovering back-pay and allowances are complex and burdensome. This Article focuses on the particular problems facing the serviceman in post-discharge cases by discussing O\u27Callahan v. United States. O\u27Callahan secured a reversal in his conviction; he brought suit for back-pay and allowances, but was denied because the statute of limitations had run a situation that was not unique. Often, claims by servicemen are rejected on grounds of laches, and definite versus indefinite expiration. These factors make it increasingly difficult for servicemen to prevail on back-pay and allowances claims. Because of the hurdles servicemen face, the author concludes that, unless he can overcome these factors, his claim for back-pay and allowances will invariably be rejected

Spectroscopic measurements of the ion velocity distribution at the base of the fast solar wind

In situ measurements of the fast solar wind reveal non-thermal distributions of electrons, protons, and minor ions extending from 0.3 au to the heliopause. The physical mechanisms responsible for these non-thermal properties and the location where these properties originate remain open questions. Here, we present spectroscopic evidence, from extreme ultraviolet spectroscopy, that the velocity distribution functions (VDFs) of minor ions are already non-Gaussian at the base of the fast solar wind in a coronal hole, at altitudes of <1.1 R ⊙. Analysis of Fe, Si, and Mg spectral lines reveals a peaked line-shape core and broad wings that can be characterized by a kappa VDF. A kappa distribution fit gives very small kappa indices off-limb of κ ≈ 1.9–2.5, indicating either (a) ion populations far from thermal equilibrium, (b) fluid motions such as non-Gaussian turbulent fluctuations or non-uniform wave motions, or (c) some combination of both. These observations provide important empirical constraints for the source region of the fast solar wind and for the theoretical models of the different acceleration, heating, and energy deposition processes therein. To the best of our knowledge, this is the first time that the ion VDF in the fast solar wind has been probed so close to its source region. The findings are also a timely precursor to the upcoming 2018 launch of the Parker Solar Probe, which will provide the closest in situ measurements of the solar wind at approximately 0.04 au (8.5 solar radii)

Upgrade of the Minos+ Experiment Data Acquisition for the High Energy NuMI Beam Run

The Minos+ experiment is an extension of the Minos experiment at a higher energy and more intense neutrino beam, with the data collection having begun in the fall of 2013. The neutrino beam is provided by the Neutrinos from the Main Injector (NuMI) beam-line at Fermi National Accelerator Laboratory (Fermilab). The detector apparatus consists of two main detectors, one underground at Fermilab and the other in Soudan, Minnesota with the purpose of studying neutrino oscillations at a base line of 735 km. The original data acquisition system has been running for several years collecting data from NuMI, but with the extended run from 2013, parts of the system needed to be replaced due to obsolescence, reliability problems, and data throughput limitations. Specifically, we have replaced the front-end readout controllers, event builder, and data acquisition computing and trigger processing farms with modern, modular and reliable devices with few single points of failure. The new system is based on gigabit Ethernet TCP/IP communication to implement the event building and concatenation of data from many front-end VME readout crates. The simplicity and partitionability of the new system greatly eases the debugging and diagnosing process. The new system improves throughput by about a factor of three compared to the old system, up to 800 megabits per second, and has proven robust and reliable in the current run.Comment: 3 page

The three-dimensional Event-Driven Graphics Environment (3D-EDGE)

Stanford Telecom developed the Three-Dimensional Event-Driven Graphics Environment (3D-EDGE) for NASA GSFC's (GSFC) Communications Link Analysis and Simulation System (CLASS). 3D-EDGE consists of a library of object-oriented subroutines which allow engineers with little or no computer graphics experience to programmatically manipulate, render, animate, and access complex three-dimensional objects

Process Control Systems in the Chemical Industry: Safety vs. Security

Traditionally, the primary focus of the chemical industry has been safety and productivity. However, recent threats to our nation’s critical infrastructure have prompted a tightening of security measures across many different industry sectors. Reducing vulnerabilities of control systems against physical and cyber attack is necessary to ensure the safety, security and effective functioning of these systems. The U.S. Department of Homeland Security has developed a strategy to secure these vulnerabilities. Crucial to this strategy is the Control Systems Security and Test Center (CSSTC) established to test and analyze control systems equipment. In addition, the CSSTC promotes a proactive, collaborative approach to increase industry's awareness of standards, products and processes that can enhance the security of control systems. This paper outlines measures that can be taken to enhance the cybersecurity of process control systems in the chemical sector

Contrasts in China and Soviet reform: sub-national and national causes

Why did reform in China and the former Soviet Union produce drastically different outcomes? Why did some provinces in China embrace faster economic reform than others? This article argues that the state sector and reform initiatives in the sub-national units, reform strategies, entrenchment and maturation of central planning, the size of the defence industry, policy choice and the historical context help explain the differences in Soviet and Chinese reform courses and outcomes. A predominant state sector in the former Soviet republics had stifled local reform initiatives. Gorbachev resorted to democratisation in order to unbolt the gate for popular support for marketisation, yet resulting in the breakup of the Soviet Union and destabilising the economy. In China, some provinces had sizable non-state sectors and were inclined to push forth marketization. Reform resulted in expanding non-state sectors, generating high growth and encouraging the regime to maintain its monopoly of power. China’s reform also benefited from a yet-to-be-entrenched and rudimentary central planning, a small defence sector, popular backlash against past policies, and reformist pragmatic strategy
