We’ve seen that semialgebraic Teddy and semialgebraic Lambkin are both images of a four-dimensional ball. Could they be images of each other? The Teddy-Lambkin Theorem Ursula Whitcher Mathematical Reviews (AMS) My given name means bear—it’s the same root as the constellation Ursa Major—so growing up I had a huge collection... Read more
If we were working with low dosages and using the correlation between dosage and outcomes as our metric of assessing effectiveness, we might underestimate how well the drug is actually working...
