Challenging Buckley v. Valeo: A Legal Strategy

In its 1976 ruling in Buckley v. Valeo, the United States Supreme Court sanctioned a system of unlimited campaign spending in federal elections. Since that ruling, this nation has witnessed an explosion of political expenditures. The 1996 election cycle marked the most expensive election in U.S. history, with congressional and presidential candidates spending a total of more than $2 billion. Campaign spending has also dramatically risen in state and local elections across the country. Unlimited spending poses a serious threat to our democratic process. It undermines public confidence in our elections and in our democratic institutions. It presents an increased danger of actual corruption as large contributors dominate the financing of public election campaigns. It places enormous time pressures on officeholders running for re-election, interfering with their ability to carry out their governing duties. It enables candidates with wealth or access to wealth to drown out the voices of lesserfunded candidates and their supporters. It violates the promise of political equality

Development of a Robust and Efficient Parallel Solver for Unsteady Turbomachinery Flows

The traditional design and analysis practice for advanced propulsion systems relies heavily on expensive full-scale prototype development and testing. Over the past decade, use of high-fidelity analysis and design tools such as CFD early in the product development cycle has been identified as one way to alleviate testing costs and to develop these devices better, faster and cheaper. In the design of advanced propulsion systems, CFD plays a major role in defining the required performance over the entire flight regime, as well as in testing the sensitivity of the design to the different modes of operation. Increased emphasis is being placed on developing and applying CFD models to simulate the flow field environments and performance of advanced propulsion systems. This necessitates the development of next generation computational tools which can be used effectively and reliably in a design environment. The turbomachinery simulation capability presented here is being developed in a computational tool called Loci-STREAM [1]. It integrates proven numerical methods for generalized grids and state-of-the-art physical models in a novel rule-based programming framework called Loci [2] which allows: (a) seamless integration of multidisciplinary physics in a unified manner, and (b) automatic handling of massively parallel computing. The objective is to be able to routinely simulate problems involving complex geometries requiring large unstructured grids and complex multidisciplinary physics. An immediate application of interest is simulation of unsteady flows in rocket turbopumps, particularly in cryogenic liquid rocket engines. The key components of the overall methodology presented in this paper are the following: (a) high fidelity unsteady simulation capability based on Detached Eddy Simulation (DES) in conjunction with second-order temporal discretization, (b) compliance with Geometric Conservation Law (GCL) in order to maintain conservative property on moving meshes for second-order time-stepping scheme, (c) a novel cloud-of-points interpolation method (based on a fast parallel kd-tree search algorithm) for interfaces between turbomachinery components in relative motion which is demonstrated to be highly scalable, and (d) demonstrated accuracy and parallel scalability on large grids (approx 250 million cells) in full turbomachinery geometries

Gold substrate-induced single-mode lasing of GaN nanowires

We demonstrate a method for mode-selection by coupling a GaN nanowire laser to an underlying gold substrate. Multimode lasing of GaN nanowires is converted to single-mode behavior following placement onto a gold film. A mode-dependent loss is generated by the absorbing substrate to suppress multiple transverse-mode operation with a concomitant increase in lasing threshold of only ∼13%. This method provides greater flexibility in realizing practical single-mode nanowire lasers and offers insight into the design of metal-contacted nanoscale optoelectronics

Effects of potassium depletion on renal tubular chloride transport in the rat

Effects of potassium depletion on renal tubular chloride transport in the rat. Potassium depletion (KD) causes renal chloride-wasting. To investigate the effects of KD on renal tubular reabsorption of chloride, balance, clearance, micropuncture, and microinjection studies were performed on potassium-depleted rats. KD was produced by omitting potassium from the diet and by administration of DOC A on days 2 and 3; rats were studied on days 9 to 12. Diets were chloride-free in both control and KD groups. In the KD group, balance experiments confirmed greater chloride depletion and continued chloride-wasting, and clearance studies showed an increased FECl. Muscle potassium was reduced by 27% as compared to control. Whole kidney and single nephron GFR were reduced in KD rats to 72 and 74% of control. Fractional (6 ± 6% vs. 22 ± 4%, P < 0.05) and absolute chloride reabsorption in the proximal tubule were reduced in KD, and chloride delivery out of the proximal tubule was not different. Fractional reabsorption of delivered chloride was reduced in the loop of Henle (92 ± 0.8% in KD vs. 95 ± 0.7% in control, P < 0.02). Transtubular chloride ratio (0.28 ± 0.02 vs. 0.21 ± 0.02, P < 0.02) was increased at the early distal tubule. Fractional delivery of chloride (8 ± 0.9 vs. 5 ± 0.5%, P < 0.02), and fluid (26 ± 1 vs. 22 ± 1%, P < 0.05) were also increased in KD at the early distal tubule. Recovery of chloride 36 injected into late distal tubules was 88 ± 1% on a normal chloride intake, 62 ± 2% in chloride depletion, and 88 ± 2% in potassium and chloride depletion. Thus, KD depresses chloride reabsorption in the proximal tubule and in the loop of Henle, and it decreases chloride 36 efflux from the collecting duct
