Bitmap indexes are known to be efficient for ad-hoc range queries that are common in data warehousing and scientific applications. However, they suffer from the curse of cardinality, that is, their efficiency deteriorates as attribute cardinalities increase. A number of strategies have been proposed, but none of them addresses the problem adequately. In this paper, we propose a novel binned bitmap index that greatly reduces the cost to answer queries, and therefore breaks the curse of cardinality. The key idea is to augment the binned index with an Order-preserving Bin-based Clustering (OrBiC) structure. This data structure significantly reduces the I/O operations needed to resolve records that cannot be resolved with the bitmaps. To further improve the proposed index structure, we also present a strategy to create single-valued bins for frequent values. This strategy reduces index sizes and improves query processing speed. Overall, the binned indexes with OrBiC great improves the query processing speed, and are 3 - 25 times faster than the best available indexes for high-cardinality data.

A letter report issued by the Government Accountability Office with an abstract that begins "Estimated to reach $15 billion by 2015, the Department of Defense's (DOD) prescription drug spending has been a growing concern for the federal government. The John Warner National Defense Authorization Act (NDAA) for Fiscal Year 2007 required GAO to examine DOD's pharmacy benefits program. Specifically, as discussed with the committees of jurisdiction, GAO examined DOD's prescription drug spending trends from fiscal years 2000 through 2006 and DOD's key efforts to limit its prescription drug spending. To conduct this work, GAO analyzed DOD's data on spending trends, including trends in beneficiary pharmacy use. GAO also assessed DOD's cost avoidance data and the agency's efforts to limit spending through its uniform formulary, which is a list of preferred drugs available to all beneficiaries. GAO interviewed DOD officials about these and other efforts to limit spending."

Pteris vittata is a fern that is extraordinary in its ability to tolerate hyperaccumulate high levels of arsenic (As). The goals of the proposed research, to identify the genes that are necessary for As hyperaccumulation in P. vittata using molecular and genetic approaches and to understand the physiology of arsenic uptake and distribution in the living plant, were accomplished during the funding period. The genes that have been identified may ultimately enable the engineering or selection of other plants capable of As hyperaccumulation. This is important for the phytoremediation of arsenic-contaminated soils in areas where P. vittata cannot grow.

An improved HVAC system for portable classrooms was specified to address key problems in existing units. These included low energy efficiency, poor control of and provision for adequate ventilation, and excessive acoustic noise. Working with industry, a prototype improved heat pump air conditioner was developed to meet the specification. A one-year measurement-intensive field-test of ten of these IHPAC systems was conducted in occupied classrooms in two distinct California climates. These measurements are compared to those made in parallel in side by side portable classrooms equipped with standard 10 SEER heat pump air conditioner equipment. The IHPAC units were found to work as designed, providing predicted annual energy efficiency improvements of about 36 percent to 42 percent across California's climate zones, relative to 10 SEER units. Classroom ventilation was vastly improved as evidenced by far lower indoor minus outdoor CO2 concentrations. TheIHPAC units were found to provide ventilation that meets both California State energy and occupational codes and the ASHRAE minimum ventilation requirements; the classrooms equipped with the 10 SEER equipment universally did not meet these targets. The IHPAC system provided a major improvement in indoor acoustic conditions. HVAC system generated background noise was reduced in fan-only and fan and compressor …

The objective of this research was to assess applicability of a technique known as hyperelastic warping for the measurement of local strains in the left ventricle (LV) directly from microPET image data sets. The technique uses differences in image intensities between template (reference) and target (loaded) image data sets to generate a body force that deforms a finite element (FE) representation of the template so that it registers with the target images. For validation, the template image was defined as the end-systolic microPET image data set from a Wistar Kyoto (WKY) rat. The target image was created by mapping the template image using the deformation results obtained from a FE model of diastolic filling. Regression analysis revealed highly significant correlations between the simulated forward FE solution and image derived warping predictions for fiber stretch (R2 = 0.96), circumferential strain (R2 = 0.96), radial strain (R2 = 0.93), and longitudinal strain (R2 = 0.76) (p<0.001for all cases). The technology was applied to microPET image data of two spontaneously hypertensive rats (SHR) and a WKY control. Regional analysis revealed that, the lateral freewall in the SHR subjects showed the greatest deformation compared with the other wall segments. This work indicates that warping …

We have developed complementary soft x-ray scattering and reflectometry techniques that allow for the morphological analysis of thin polymer films without resorting to chemical modification or isotopic 2 labeling. With these techniques, we achieve significant, x-ray energy-dependent contrast between carbon atoms in different chemical environments using soft x-ray resonance at the carbon edge. Because carbon-containing samples absorb strongly in this region, the scattering length density depends on both the real and imaginary parts of the atomic scattering factors. Using a model polymer film of poly(styrene-b-methyl methacrylate), we show that the soft x-ray reflectivity data is much more sensitive to these atomic scattering factors than the soft x-ray scattering data. Nevertheless, fits to both types of data yield useful morphological details on the polymer?slamellar structure that are consistent with each other and with literature values.

Correspondence issued by the Government Accountability Office with an abstract that begins "Temporomandibular joint and muscle disorders (TMJD) include a heterogeneous group of disorders with overlapping--but not identical--signs and symptoms. Symptoms of TMJDs vary, but typically include pain in the jaw joint and surrounding muscles. Other symptoms may include limited or no movement of the jaw joint, clicking or grating in the jaw joint when opening or closing the mouth, headaches, and shoulder or back pain. Most people with TMJDs have relatively mild forms of these disorders with symptoms that diminish without treatment. However, a small number of individuals develop significant, long-term problems, including persistent and debilitating pain and loss of jaw function. Although some TMJDs are due to a specific known cause, such as jaw injury or arthritis, the causes of many TMJDs are unknown. While the level of understanding about these conditions has evolved with scientific advancements, diagnosis and treatment are difficult because the exact causes and patterns of symptoms remain unclear. The National Institutes of Health (NIH), an agency within the Department of Health and Human Services (HHS), funds research on the causes of, treatments for, and other aspects of TMJDs. The NIH is organized into 27 …
