Is Hedysarum mackenziei (Wild Sweet Pea) Actually Toxic?

Hedysarum mackenziei Richardson (wild sweet pea, bear root) is widely regarded as toxic and warnings about confusing it with its edible cousin Hedysarum alpinum Richardson (Eskimo potato) abound. To find the chemical basis for this claim, we performed an exhaustive comparison of the secondary chemistry between the two plants as well as a search for nitrogen containing metabolites (alkaloids) in...

Notes on Galton’s Sweet Pea Data

What is actually teleported?

There are no “unknown quantum states.” It’s a contradiction in terms. Moreover, Alice and Bob are only inanimate objects. They know nothing. What is teleported instantaneously from one system (Alice) to another system (Bob) is the applicability of the preparer’s knowledge to the state of a particular qubit in these systems. The operation necessitates dual classical and quantum channels. Other e...

Is pertussis actually reemerging ?

In this paper, we introduce a spatially explicit, individual-based model developed to simulate the dynamics of pertussis in a small population. With this simulation approach, complex epidemic systems can be built using information on parasite population structure (strain diversity, virulence diversity, etc.), human population structure (individual risk, age structure, interaction matrices, immu...

Is interactivity actually important?

It appears that it is a well-accepted assumption that interactivity will improve the entertainment and/or learning value of a media. This paper reviews various studies exploring the role of interactivity and reports on a study conducted to see whether a novice could learn some basic skills on how to be a customs officer from watching a game demonstration compared to being an active participant ...
