Analysis of the structure of complex networks at different resolution levels
Modular structure is ubiquitous in real-world complex networks, and its detection is important because it gives insights in the structure-functionality relationship. The standard approach is based on the optimization of a quality function, modularity, which is a relative quality measure for a partition of a network into modules. Recently some authors have pointed out that the optimization of modularity has a fundamental drawback: the existence of a resolution limit beyond which no modular structure can be detected even though these modules might have own entity. The reason is that several topological descriptions of the network coexist at different scales, which is, in general, a fingerprint of complex systems. Here we propose a method that allows for multiple resolution screening of the modular structure. The method has been validated using synthetic networks, discovering the predefined structures at all scales. Its application to two real social networks allows to find the exact splits reported in the literature, as well as the substructure beyond the actual split.

Measurements of the Semileptonic Decays \Bb\to D\ell\nub and \Bb\to D^*\ell\nub Using a Global Fit to D X\ell\nub Final States
Semileptonic {bar B} decays to DX{ell}{bar {nu}} ({ell} = e or {mu}) are selected by reconstructing D{sup 0}{ell} and D{sup +}{ell} combinations from a sample of 230 million {Upsilon}(4S) {yields} B{bar B} decays recorded with the BABAR detector at the PEP-II e{sup +}e{sup -} collider at SLAC. A global fit to these samples in a 3-dimensional space of kinematic variables is used to determine the branching fractions {Beta}(B{sup -} {yields} D{sup 0}{ell}{bar {nu}}) = 2.36 {+-} 0.03 {+-} 0.12% and {Beta}(B{sup -} {yields} D*{sup 0}{ell}{bar {nu}}) = (5.37 {+-} 0.02 {+-} 0.21)% where the errors are statistical and systematic, respectively. The fit also determines form factor parameters in a HQET-based parameterization, resulting in {rho}{sub D}{sup 2} = 1.22 {+-} 0.04 {+-} 0.07 for {bar B} {yields} D{ell}{bar {nu}} and {rho}{sub D*}{sup 2} = 1.21 {+-} 0.02 {+-} 0.07 for {bar B} {yields} D*{ell}{bar {nu}}. These values are used to obtain the product of the CKM matrix element |V{sub cb}| times the form factor at the zero recoil point for both {bar B} {yields} D{ell}{bar {nu}} decays, G(1)|V{sub cb}| = (43.8 {+-} 0.8 {+-} 2.3) x 10{sup -3}, and for {bar B} {yields} D*{ell}{bar {nu}} decays, F(1)|V{sub cb}| = (35.7 {+-} …

Argonne's Laboratory Computing Center - 2007 Annual Report.
Argonne National Laboratory founded the Laboratory Computing Resource Center (LCRC) in the spring of 2002 to help meet pressing program needs for computational modeling, simulation, and analysis. The guiding mission is to provide critical computing resources that accelerate the development of high-performance computing expertise, applications, and computations to meet the Laboratory's challenging science and engineering missions. In September 2002 the LCRC deployed a 350-node computing cluster from Linux NetworX to address Laboratory needs for mid-range supercomputing. This cluster, named 'Jazz', achieved over a teraflop of computing power (1012 floating-point calculations per second) on standard tests, making it the Laboratory's first terascale computing system and one of the 50 fastest computers in the world at the time. Jazz was made available to early users in November 2002 while the system was undergoing development and configuration. In April 2003, Jazz was officially made available for production operation. Since then, the Jazz user community has grown steadily. By the end of fiscal year 2007, there were over 60 active projects representing a wide cross-section of Laboratory expertise, including work in biosciences, chemistry, climate, computer science, engineering applications, environmental science, geoscience, information science, materials science, mathematics, nanoscience, nuclear engineering, and physics. Most important, many …

In Situ Microbial Community Control of the Stability of Bio-reduced Uranium
In aerobic aquifers typical of many Department of Energy (DOE) legacy waste sites, uranium is present in the oxidized U(VI) form which is more soluble and thus more mobile. Field experiments at the Old Rifle UMTRA site have demonstrated that biostimulation by electron donor addition (acetate) promotes biological U(VI) reduction (2). However, U(VI) reduction is reversible and oxidative dissolution of precipitated U(IV) after the cessation of electron donor addition remains a critical issue for the application of biostimulation as a treatment technology. Despite the potential for oxidative dissolution, field experiments at the Old Rifle site have shown that rapid reoxidation of bio-reduced uranium does not occur and U(VI) concentrations can remain at approximately 20% of background levels for more than one year. The extent of post-amendment U(VI) removal and the maintenance of bioreduced uranium may result from many factors including U(VI) sorption to iron-containing mineral phases, generation of H2S or FeS0.9, or the preferential sorption of U(VI) by microbial cells or biopolymers, but the processes controlling the reduction and in situ reoxidation rates are not known. To investigate the role of microbial community composition in the maintenance of bioreduced uranium, in-well sediment incubators (ISIs) were developed allowing field deployment of …

SLUDGE BATCH 5 ACCEPTANCE EVALUATION RADIONUCLIDE CONCENTRATIONS IN TANK 51 SB5 QUALIFICATION SAMPLE PREPARED AT SRNL
Presented in this report are radionuclide concentrations required as part of the program of qualifying Sludge Batch Five (SB5) for processing in the Defense Waste Processing Facility (DWPF). Part of this SB5 material is currently in Tank 51 being washed and prepared for transfer to Tank 40. The acceptance evaluation needs to be completed prior to the transfer of the material in Tank 51 to Tank 40 to complete the formation of SB5. The sludge slurry in Tank 40 has already been qualified for DWPF and is currently being processed as SB4. The radionuclide concentrations were measured or estimated in the Tank 51 SB5 Qualification Sample prepared at Savannah River National Laboratory (SRNL). This sample was prepared from the three liter sample of Tank 51 sludge slurry taken on March 21, 2008. The sample was delivered to SRNL where it was initially characterized in the Shielded Cells. Under direction of the Liquid Waste Organization it was then modified by five washes, six decants, an addition of Pu/Be from Canyon Tank 16.4, and an addition of NaNO2. This final slurry now has a composition expected to be similar to that of the slurry in Tank 51 after final preparations have been …

Investigations of Solar Prominence Dynamics Using Laboratory Simulations
Laboratory experiments simulating many of the dynamical features of solar coronal loops have been carried out. These experiments manifest collimation, kinking, jet flows, and S-shapes. Diagnostics include high-speed photography and x-ray detectors. Two loops having opposite or the same magnetic helicity polarities have been merged and it is found that counter-helicity merging provides much greater x-ray emission. A non-MHD particle orbit instability has been discovered whereby ions going in the opposite direction of the current flow direction can be ejected from a magnetic flux tube.

Beam Head Erosion in Self-Ionized Plasma Wakefield Accelerators
In the recent plasma wakefield accelerator experiments at SLAC, the energy of the particles in the tail of the 42 GeV electron beam were doubled in less than one meter [1]. Simulations suggest that the acceleration length was limited by a new phenomenon--beam head erosion in self-ionized plasmas. In vacuum, a particle beam expands transversely in a distance given by {beta}*. In the blowout regime of a plasma wakefield [2], the majority of the beam is focused by the ion channel, while the beam head slowly spreads since it takes a finite time for the ion channel to form. It is observed that in self-ionized plasmas, the head spreading is exacerbated compared to that in pre-ionized plasmas, causing the ionization front to move backward (erode). A simple theoretical model is used to estimate the upper limit of the erosion rate for a bi-gaussian beam by assuming free expansion of the beam head before the ionization front. Comparison with simulations suggests that half this maximum value can serve as an estimate for the erosion rate. Critical parameters to the erosion rate are discussed.

Tax Gap: Administration Proposal to Require Information Reporting on Merchant Payment Card Reimbursements
The high current and forecast budget deficits as well as pay-as-you-go (PAYGO) procedures have resulted in congressional and executive branch interest in raising additional revenue through proposals for improved tax compliance. The Bush Administration’s FY2009 budget includes a proposal (the proposal) to require each payment card processor to inform the IRS on the net dollar amount paid to reimburse each merchant (i.e., seller) for his payment card receipts in a calendar year. Payment cards consist of both credit cards and debit cards. This report examines the proposal by describing current law, presenting the proposal contained in the FY2009 budget, describing the structure of the payment card industry, analyzing the justifications for the proposal, explaining the criticisms of the proposal, and offering concluding observations.
