Compound Lucas Magic Squares [PDF]
arXiv, 2021 We review a general parameterization of an order-3 magic square derived by Lucas and we compound it to produce a parameterized order-9 magic square. Sequential compounding to higher order also is treated. Expressions are found for the matrices in the Jordan canonical form and the singular value decomposition of the compound Lucas magic square matrices.

Assessment of the effects of organic vs. inorganic arsenic and mercury in Caenorhabditis elegans
Current Research in Toxicology, 2022 Exposures to mercury and arsenic are known to pose significant threats to human health. Effects specific to organic vs. inorganic forms of these toxic elements are less understood however, especially for organic dimethylarsinic acid (DMA), which has ...

A Natural Discrete One Parameter Polynomial Exponential Distribution [PDF]
arXiv, 2020 In this paper, a new natural discrete version of the one parameter polynomial exponential family of distributions have been proposed and studied. The distribution is named as Natural Discrete One Parameter Polynomial Exponential (NDOPPE) distribution. Structural and reliability properties have been studied.

Journal of Neuroendocrinology, EarlyView.Abstract Exposure to methylmercury (MeHg) on breeding grounds may have numerous deleterious effects on birds, including neurotoxicity, disruption of hormones, and impaired reproduction. But it is unknown if MeHg exposure on wintering grounds can carry over and produce negative effects on the following spring breeding seasonal transition.
