This is the third volume of the monumental A History of Medicine series by the medical historian and classical scholar Plinio Prioreschi M.D., PhD.[1] A limited number of these books were published, and the reader would be fortunate to find copies of the tomes for less than $350 U.S. dollars. We have already reviewed Volume I: Primitive and Ancient Medicine (2nd ed.ition, 1995) and Volume II: G...

We consider a cross-calibration test of predictions by multiple potential experts in a stochastic environment. This test checks whether each expert is calibrated conditional on the predictions made by other experts. We show that this test is good in the sense that a true expert—one informed of the true distribution of the process—is guaranteed to pass the test no matter what the other potential...

In the October issue of Joule, Grant et al. explore how uncertainties in three CDR pathways (BECCS, DACCS, and afforestation/reforestation) can be incorporated into integrated assessment models, resulting an additional 10 gigatons CO2e requiring mitigation by 2030. This finding underscores importance accelerating research, design, development. Main TextIntegrated models (IAMs) are widely used t...

For a finite group $G$‎, ‎let $Cent(G)$ denote the set of centralizers of single elements of $G$‎. ‎In this note we prove that if $|G|leq frac{3}{2}|Cent(G)|$ and $G$ is 2-nilpotent‎, ‎then $Gcong S_3‎, ‎D_{10}$ or $S_3times S_3$‎. ‎This result gives a partial and positive answer to a conjecture raised by A‎. ‎R‎. ‎Ashrafi [On finite groups with a given number of centralizers‎, ‎Algebra‎ ‎Collo...
