Constructal law of vascular trees for facilitation of flow. [PDF]
PLoS ONE, 2014 Diverse tree structures such as blood vessels, branches of a tree and river basins exist in nature. The constructal law states that the evolution of flow structures in nature has a tendency to facilitate flow.

A note on imperfect hedging: a method for testing stability of the hedge ratio
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013 Companies producing, processing and consuming commodities in the production process often hedge their commodity expositions using derivative strategies based on different, highly correlated underlying commodities. Once the open position in a commodity is hedged using a derivative position with another underlying commodity, the appropriate hedge ratio ...

Imperfect reference standards cause biased likelihood ratios
Scandinavian Journal of Clinical and Laboratory InvestigationIn a study of the diagnostic accuracy of a quantitative biomarker, the researcher compares the concentration of the biomarker in patients with and without the disease in question. The diagnosis must be set without knowledge of the biomarker concentration, using the best reference standard available.

Small RNA pathways in mammalian oocytes
FEBS Open Bio, EarlyView.Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

FEBS Open Bio, EarlyView.The two catalytic subunits of typhoid toxin dissociate from the holotoxin in the ER of an intoxicated cell, but only CdtB exits the ER to generate immunosuppressive effects. PltA is retained in the ER and sequestered from its cytosolic target, thus allowing the anti‐inflammatory effects of CdtB to promote intestinal colonization.
