BIF: Balanced Incomplete Factorization

Incomplete factorizations represent a class of algebraic preconditioners important from both theoretical and practical points of view. While state-of-the-art preconditioners of this kind can be very useful, very large problems, arising, e.g., from discretizations of complicated operators on unstructured grids typically, still may require more robust preconditioners. High-quality incomplete fact...

Infrared broadband emission of bismuth-doped barium-aluminum-borate glasses.

We report near infrared broadband emission of bismuth-doped barium-aluminum-borate glasses. The broadband emission covers 1.3microm window in optical telecommunication systems. And it possesses wide full width at half maximum (FWHM) of ~200nm and long lifetime as long as 350micros. The luminescent properties are quite sensitive to glass compositions and excitation wavelengths. Based on energy m...

Near infrared broadband emission of bismuth-doped aluminophosphate glass.

Near infrared broadband emission characteristics of bismuth-doped aluminophosphate glass have been investigated. Broad infrared emissions peaking at 1210nm, 1173nm and 1300nm were observed when the glass was pumped by 405nm laser diode (LD), 514nm Ar+ laser and 808nm LD, respectively. The full widths at half maximum (FWHMs) are 235nm, 207nm and 300nm for the emissions at 1210nm, 1173nm and 1300...

18F-Sodium Fluoride Positron Emission Tomography

Coronary atherosclerosis is a progressive disease that involves vascular inflammation, development of cholesterol burdened atheroma, mechanisms of injury and repair, and subsequent calcification (1). Coronary artery calcification (CAC) detected with cardiac computed tomography has been shown to correlate well with overall plaque burden and is an independent predictor of cardiovascular events (2...
