Individual Accounts: What Rate of Return Would They Earn? (open access)

Individual Accounts: What Rate of Return Would They Earn?

It has been proposed to add individual accounts to Social Security in which investors could hold private securities. Calculations that project the earnings of individual accounts typically presume that they will earn a rate of return equal or close to the historical rate of return. But is there evidence that future rates of return will differ from history in predictable ways?

Pyrolytic Removal Of The Plastic Mandrel From Sputtered Beryllium Shells (open access)

Pyrolytic Removal Of The Plastic Mandrel From Sputtered Beryllium Shells

An engineering model is presented for the removal of the plastic mandrel from the inside of a sputtered Be shell. The removal is accomplished by forcing heated air in and out of the 4 to 5 {micro}m laser drilled fill hole in the capsule wall by cycling the external pressure between 2 and 5 atm. The plastic is combusted to CO{sub 2} and H{sub 2}O by this exposure, thus removing the mandrel. Calculations are presented to evaluate the various parameters in the approach. Experimental confirmation of the effectiveness of the removal is shown.

Isospin Breaking and the Chiral Condensate. (open access)

Isospin Breaking and the Chiral Condensate.

With two degenerate quarks, the chiral condensate exhibits a jump as the quark masses pass through zero. I discuss how this single transition splits into two Ising like transitions when the quarks are made non-degenerate. The order parameter is the expectation of the neutral pion field. The transitions represent long distance coherent phenomena occurring without the Dirac operator having vanishingly small eigenvalues.

Flow of Business: Typical Day on the Senate Floor

This report discusses procedures and business that usually occur every session day, and notes certain business items that may occur less frequently. Several authorities govern the daily chamber work of the Senate: the standing rules, the "standing orders," unanimous consent agreements, precedent, and tradition. Because these authorities have different influence at certain times, no Senate session day is truly typical.

HEAVY QUARK FREE ENERGIES AND SCREENING AT FINITE TEMPERATURE AND DENSITY. (open access)

HEAVY QUARK FREE ENERGIES AND SCREENING AT FINITE TEMPERATURE AND DENSITY.

We study the free energies of heavy quarks calculated from Polyakov loop correlation functions in full 2-flavour QCD using the p4-improved staggered fermion action. A small but finite baryon number density is included via Taylor expansion of the fermion determinant in the baryo-chemical potential {mu}. For temperatures above T{sub c} we extract Debye screening masses from the large distance behavior of the free energies and compare their {mu}-dependence to perturbative results.

THERMAL COOK-OFF EXPERIMENTS OF THE HMX BASED HIGH EXPLOSIVE LX-04 TO CHARACTERIZE VIOLENCE WITH VARYING CONFINEMENT (open access)

THERMAL COOK-OFF EXPERIMENTS OF THE HMX BASED HIGH EXPLOSIVE LX-04 TO CHARACTERIZE VIOLENCE WITH VARYING CONFINEMENT

Thermal cook-off experiments were carried out using LX-04 explosive (85% HMX and 15% Viton by weight) with different levels of confinement to characterize the effect of confinement on the reaction violence. These experiments involved heating a porous LX-04 sample in a stainless steel container with varying container end plate thickness and assembly bolt diameter to control overall confinement. As expected, detonation did not occur and reducing the overall confinement lowered the reaction violence. This is consistent with modeling results that predict that a lower confinement will act to lower the cook-off pressure and thus the overall burn rate which lowers the overall violence. These results suggest that controlling the overall system confinement can modify the relative safety in a given scenario.

State selective dynamics of molecules, clusters, and nanostructures (open access)

State selective dynamics of molecules, clusters, and nanostructures

Early objectives of this grant were: (1) Measure two-photon excitation of even parity excitons in liquid an solid xenon, (2) Study state-to-state energy transver between two-photon laser excited states or rare-gas atoms to other rare has atoms, (3) study reactive half-collisions between xenon and chlorine leading to the XeCl* B state, (4) measure the spectra of ro-vibrational states of cluster ions and radicals formed in high-pressure discharges and to study their dynamics, (5) measure the surface and bulk electronic states of nanoparticles produced by a unique method of synthesis--laser ablation of microspheres (LAM). Using near-field and microluminescence techniques, we obtained spectra of single nanocrystals to compare with spectra obtained in a supersonic jet apparatus using resonance excitation followed by photoionization (REMPI) with time-of-flight mass analysis. These materials combine the functional advantages obtained from the “size-tunable” properties of nanocomposite materials with the fabrication and direct-write advantages of NPs manufactured by LAM. We demostrated that CdSe nanoparticles produced by LAM were efficiient fluorescers, even when deposited dry on sapphire substrates. Si nanoparticles were fluorescent when captured in ethylene glycol. We also obtiained efficient fluorescence from Er doped phosphate glass nanopartiicles which have application to gain wafeguides in integrated optics or to nanoslush …

Gamma Spectra Resulting From the Annihilation of Positrons with Electrons in Single, Selected Core Levels of Cu, Ag and Au (open access)

Gamma Spectra Resulting From the Annihilation of Positrons with Electrons in Single, Selected Core Levels of Cu, Ag and Au

The {gamma}-ray energy spectra due to positron annihilation with the 3p core-level of Cu, the 4p core-level of Ag, and 5p core level of Au were obtained separately from the total annihilation spectrum by measuring the energies of {gamma}-rays time coincident with Auger electrons emitted as a result of filling the core-hole left by annihilation. The results of these measurements are compared to the total annihilation spectra and with LDA based theoretical calculations. A comparison of area normalized momentum distributions with the individual cores extracted from the Doppler measurements shows good qualitative agreement, however, in all three spectra, the calculated values of the momentum density appears to fall below the measured values as the momentum increases. The discrepancies between theory and experiment are well outside the statistical uncertainties of the experiment and become more pronounced with increasing Z going down the column from Cu to Ag to Au. The comparison with the experimental results clearly indicates that the calculations are not predicting the correct ratio of high momentum to low momentum spectral weight and suggest the need to improve the treatment of many body electron-positron correlation effects in annihilation as they pertain to core levels.

The Corporation for Public Broadcasting: Federal Funding Facts and Status

Congressional policymakers are closely examining federal funding for the Corporation for Public Broadcasting (CPB). Overall, 15.6% of all public television and radio broadcasting funding comes from the federal appropriations that CPB distributes. The CPB’s appropriation is allocated through a distribution formula established in its authorizing legislation. It has historically received two-year advanced appropriations.

China's Economic Conditions (open access)

China's Economic Conditions

China’s economy continues to be a concern to U.S. policymakers. On the one hand, China’s economic growth presents huge opportunities for U.S. exporters. On the other hand, the surge in Chinese exports to the United States has put competitive pressures on many U.S. industries. Many U.S. policymakers have argued that greater efforts should be made to pressure China to fully implement its WTO commitments and to change various economic policies deemed harmful to U.S. economic interests, such as its currency peg and its use of subsidies to support its SOEs. In addition, recent bids by Chinese state-owned firms to purchase various U.S. firms have raised concerns among Members over the impact such acquisitions could have on U.S. national and economic security.

Single Electron Tunneling (open access)

Single Electron Tunneling

Financial support for this project has led to advances in the science of single-electron phenomena. Our group reported the first observation of the so-called ''Coulomb Staircase'', which was produced by tunneling into ultra-small metal particles. This work showed well-defined tunneling voltage steps of width e/C and height e/RC, demonstrating tunneling quantized on the single-electron level. This work was published in a now well-cited Physical Review Letter. Single-electron physics is now a major sub-field of condensed-matter physics, and fundamental work in the area continues to be conducted by tunneling in ultra-small metal particles. In addition, there are now single-electron transistors that add a controlling gate to modulate the charge on ultra-small photolithographically defined capacitive elements. Single-electron transistors are now at the heart of at least one experimental quantum-computer element, and single-electron transistor pumps may soon be used to define fundamental quantities such as the farad (capacitance) and the ampere (current). Novel computer technology based on single-electron quantum dots is also being developed. In related work, our group played the leading role in the explanation of experimental results observed during the initial phases of tunneling experiments with the high-temperature superconductors. When so-called ''multiple-gap'' tunneling was reported, the phenomenon was correctly identified by …
