On matrix model partition functions for QCD with chemical potential [PDF]
, 2004 Partition functions of two different matrix models for QCD with chemical potential are computed for an arbitrary number of quark and complex conjugate anti-quark flavors. In the large-N limit of weak nonhermiticity complete agreement is found between the

Tooth matrix analysis for biomonitoring of organic chemical exposure: Current status, challenges, and opportunities [PDF]
Environmental Research, 2015 Epidemiological evidence supports associations between prenatal exposure to environmental organic chemicals and childhood health impairments. Unlike the common choice of biological matrices such as urine and blood that can be limited by short half-lives for some chemicals, teeth provide a stable repository for chemicals with half-life in the order of ...
