A possible evolutionary origin for the Mn4 cluster of the photosynthetic water oxidation complex from natural MnO2 precipitates in the early ocean
The photosynthetic water oxidation complex consists of a cluster of 4 Mn atoms bridged by O atoms, associated with Ca2+ and Cl- and incorporated into protein. The structure is similar in higher plants and algae, as well as in cyanobacteria of more ancient lineage, dating back more than 2.5 Ga on Earth. It has been proposed that the proto-enzyme derived from a component of a natural early marine manganese precipitate that contained a CaMn4O9 cluster. A variety of MnO2 minerals is found in nature. Three major classes are spinels, sheet-like layered structures and 3-dimensional networks that contain parallel tunnels. These relatively open structures readily incorporate cations (Na+, Li+, Mg2+, Ca2+, Ba2+, H+ and even Mn2+) and water. The minerals have different ratios of Mn(III) and Mn(IV) octahedrally coordinated to oxygens. Using X-ray spectroscopy we compare the chemical structures of Mn in the minerals with what is known about the arrangement in the water-oxidation complex to define the parameters of a structural model for the photosynthetic catalytic site. This comparison provides for the structural model a set of candidate Mn4 clusters -- some previously proposed and considered and others entirely novel.

Predicting sporadic Grid data transfers.
The increasingly common practice of (1) replicating datasets and (2) using resources as distributed data stores in Grid environments has lead to the problem of determining which replica can be accessed most efficiently. Due to diverse performance characteristics and load variations of several components in the end-to-end path linking these various locations, selecting a replica location from among many requires accurate prediction information of end-to-end data transfer times between the sources and sinks. In this paper, we present a prediction system that is based on combining end-to-end application throughput observations and network load variations, drawing from their merits of capturing whole system performance and variations in load patterns respectively. We develop a set of regression models to derive predictions that characterize the effect of network load variations on file transfer times. We apply these techniques to the GridFTP data movement tool, part of the Globus Toolkit{sup TM}, and observe performance gains of up to 10% in prediction accuracy when compared to approaches based on past system behavior in isolation.

LES SOFTWARE FOR THE DESIGN OF LOW EMISSION COMBUSTION SYSTEMS FOR VISION 21 PLANTS
Further development of a combustion Large Eddy Simulation (LES) code for the design of advanced gaseous combustion systems is described in this sixth quarterly report. CFD Research Corporation (CFDRC) is developing the LES module within the parallel, unstructured solver included in the commercial CFD-ACE+ software. In this quarter, in-situ adaptive tabulation (ISAT) for efficient chemical rate storage and retrieval was implemented and tested within the Linear Eddy Model (LEM). ISAT type 3 is being tested so that extrapolation can be performed and further improve the retrieval rate. Further testing of the LEM for subgrid chemistry was performed for parallel applications and for multi-step chemistry. Validation of the software on backstep and bluff-body reacting cases were performed. Initial calculations of the SimVal experiment at Georgia Tech using their LES code were performed. Georgia Tech continues the effort to parameterize the LEM over composition space so that a neural net can be used efficiently in the combustion LES code. A new and improved Artificial Neural Network (ANN), with log-transformed output, for the 1-step chemistry was implemented in CFDRC's LES code and gave reasonable results. This quarter, the 2nd consortium meeting was held at CFDRC. Next quarter, LES software development and testing will …

A study on D0 Run2b stave structural performance
Two different structural solutions have been proposed and studied for the D0 Run2b stave. The way the stave structural stiffness is achieved in both designs is essentially the same: the structural material is displaced as far as possible from the neutral axis in order to increase the bending moment of the stave. The agreement of the measured data with what has been theoretically predicted is excellent. The C channel stave with dog-bones glued on top of the sensor (stave No.2) has outperformed the other mockups with a predicted sag of 51{micro}m for a distributed load of 2.28 N/m [0.013 lbf/in] and a consequent natural frequency of 89.2Hz. The other three C channel staves with the dog-bones not glued on the sensor have a bending stiffness that is -19.0%, -10.8%, +4.0% of that of stave No.2, being 11.0%, 7.8%, 15.1% lighter respectively. An optimized stave structural proposal with 130.5% of the design stiffness within the mass budget is presented at the end of this paper.

A Summary Report on the NPH Evaluation of 105-L Disassembly Basin
The L Area Disassembly Basin (LDB) is evaluated for the natural phenomena hazards (NPH) effects due to earthquake, wind, and tornado in accordance with DOE Order 420.1 and DOE-STD-1020. The deterministic analysis is performed for a Performance Category 3 (PC3) level of loads. Savannah River Site (SRS) specific NPH loads and design criteria are obtained from Engineering Standard 01060. It is demonstrated that the demand to capacity (D/C) ratios for primary and significant structural elements are acceptable (equal to or less than 1.0). Thus, 105-L Disassembly Basin building structure is qualified for the PC3 NPH effects in accordance with DOE Order 420.1.

Tax-Exempt Organizations: Improvements Possible in Public, IRS, and State Oversight of Charities
A letter report issued by the General Accounting Office with an abstract that begins "The tremendous outpouring of charitable donations in response to September 11 has raised concerns about whether some charities are spending too much on fundraising and management and too little on the charitable purposes related to their tax-exempt status. GAO found that Form 990 expense data is inadequate for public oversight purposes because charities have considerable discretion in recording their expenses when it comes to fundraising, management, and charitable services. The Internal Revenue Service (IRS) lacks data on the type and extent of possible compliance issues among charities. Moreover, IRS oversight of charities suffers from a lack of results-oriented goals and strategies. Concerns have also been raised that IRS's resources have not kept pace with the growth in the charitable sector, and some measures suggest that available resources may not be used as effectively as in the past. State officials consider inadequate the charity data IRS shares with them. IRS does not proactively share some data that states are permitted to receive, such as denials and revocations of charities' tax-exempt status. Federal law prohibits sharing some data that state officials believe would be valuable, such as the …

Transmission electron microscopy studies of electrical active GaAs/GaN interface obtained by wafer bonding
Transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX) studies of GaAs/GaN interfaces, obtained by direct wafer bonding, are presented. TEM observations show that most of the interface area was well bonded. A thin oxide layer, confirmed by EDX, was present at the interface in the well-bonded regions. Plan-view TEM studies showed the presence of two dislocation networks in such regions. They formed to accommodate: (1) tilt between bonded crystals and (2) strain, which appeared during sample cooling due to mismatch in thermal expansion coefficients. Asymmetrical, often elongated, cavities, formed on the GaAs side, were present at the interface between the well-bonded regions. It was shown by EDX that the walls of these cavities are covered with native oxide.

Ultrasonic Technology for Characterizing Laser Damage in Optics
An ultrasonic technique was developed to detect and characterize laser damage in critical optics. During normal usage, sub critical flaws induced by high laser fluence can grow to critical size and potentially can cause unanticipated failure of the optics. This ultrasonic technique monitors the optic in situ and provides a quick, reliable way to quantify the location, number and, ultimately, the size of defects that may initiate and grow during firing of the laser. The feasibility of detecting and sizing laser-induced damage with an ultrasonic technology was theoretically and experimentally demonstrated. An experiment was conducted whereby ultrasonic data was acquired in situ on an optic as it was damaged by a laser. This monitoring of laser induced damage clearly demonstrated the potential for ultrasonic monitoring of critical optics for laser-induced damage.

VA Health Care: Changes Needed to Improve Resource Allocation
Testimony issued by the General Accounting Office with an abstract that begins "The Veterans Equitable Resource Allocation (VERA) system allocated $17.8 billion of its $20.3 billion health care budget to 22 regional health care networks in fiscal year 2001. Before Vera resources were allocated to facilities on the basis of their historical expenditures. By aligning resources with workloads VERA shifted about$921 million among VA's networks in fiscal year 2001. VERA's design is reasonable for equitably allocating resources, but improvements could better allocate comparable resources for comparable workloads. VERA's allocations are based primarily on network workload, with adjustments made for factors beyond the control of network management. These include the health care needs of veterans and some local cost differences. VERA's design also protects patients from the effects of network budget shortfalls. However, GAO found that $200 million annually that could be reallocated to better align network resources with workloads. First, VERA's measurement of network workload is not accurate enough to determine each network's allocation because VERA excludes most veterans with higher incomes who do not have service-connected disabilities--about one-fifth of VA's workload. Second, VERA does not accurately adjust for cost differences among networks for differences in patients' health care needs …

Verification Test Report for CFAST 3.1.6
Fire is a significant hazard in most facilities that handle radioactive materials. The severity of fire varies with room arrangement, combustible loading, ventilation and protective system response. The complexity of even simple situations can be unwieldy to solve by hand calculations. Thus, computer simulation of the fire severity has become an important tool in characterizing fire risk. The Savannah River Site (SRS), a Department of Energy facility, has been using the Consolidated Model of Fire Growth and Smoke Transport (CFAST) software to complete such deterministic evaluations to better characterize the nuclear facility fire severity. To fully utilize CFAST at SRS it is necessary to demonstrate that CFAST produces valid analytic solutions over its range of use. This report describes the primary verification exercise that is required to establish that CFAST, and its user interface program FAST, produce valid analytic solutions. This verification exercise may be used to check the fu nctionality of FAST and as a training tool to familiarize users with the software. In addition, the report consolidates the lessons learned by the SRS staff in using FAST and CFAST as fire modeling tools.
