“The only way that these sort of things can be effective, if we take that model from other countries, is if you test far more cases than come up positive,” says Sham Kakade, a computer scientist at the University of Washington and a coauthor of PACT, a similar set of contact tracing protocols.
Kristin Laidre, an animal ecologist at the University of Washington and a coauthor, says the melting summer sea ice is causing trouble for big mammals: polar bears, walruses, and seals.
In an April 2018 paper coauthored with collaborators from the University of Washington and DeepMind, the Google-owned artificial intelligence company, Bowman introduced a battery of nine reading-comprehension tasks for computers called GLUE (General Language Understanding Evaluation).
Now a professor at the University of Washington, Page oversees three studies of new contraceptive methods for men: a hormonal pill, which suppresses sperm production with a compound called DMU; an injection, modeled after the Depo-Provera shot for women; and the NES/T gel, which uses a type of progestin called nesterone in concert with testosterone.
