Numerical investigation of granular filter under the bed of a canal

Applied Water Science, 2019
To protect canal beds against erosion and to prevent seepage from the bottom or side of a canal, impermeable linings are often used. These linings can suffer from several problems including damage due to uplift pressure when the groundwater table is high.

Simulating 500 million years of evolution with a language model.

Science
More than three billion years of evolution have produced an image of biology encoded into the space of natural proteins. Here we show that language models trained at scale on evolutionary data can generate functional proteins that are far away from known
