(AI/AN) people continue to have disproportionately higher rates of illness and higher mortality rates when compared with other Americans. AI/ANs die at higher rates than other Americans from tuberculosis (500 percent higher), alcoholism (550 percent higher), diabetes (200 percent higher), unintentional injuries (150 percent higher), homicide (100 percent higher), and suicide (70 percent higher)...

This report proposes a standard method to characterize variability and sensitivity of functional neuroimaging experiments. Most functional neuroimaging analyses result in statistic images of signal-to-noise. However, it is essential to examine both signal and noise individually, to characterize sensitivity and to identify artifacts. Confidence intervals simultaneous convey signal and noise but ...

The difference between the disease rates of two groups, one exposed and one not exposed to a suspected aetiological factor, is a useful measure of the risk associated with the factor. This measure is of most interest when the association is considered causal, and has been termed the attributable risk (MacMahon and Pugh, 1970). Expressed as a percentage of the total disease rate in a group (the ...

Data from the National Medical Care Utilization and Expenditure Survey of 1980 are used to examine the characteristics of high-volume users of health care services, contrasting them with low-volume users and those who used no services at all. The three major types of medical care services examined are hospital inpatient care, ambulatory visits, and prescribed medications. Low users were defined...

High-quality ultrathin two-dimensional nanosheets of α-Ni(OH)2 are synthesized at large scale via microwave-assisted liquid-phase growth under low-temperature atmospheric conditions. After heat treatment, non-layered NiO nanosheets are obtained while maintaining their original frame structure. The well-defined and freestanding nanosheets exhibit a micron-sized planar area and ultrathin thicknes...
