In one specific interaction, phages participate in these bacterial communities by lysing... Read More

Dynamic Load Balancing in Networks Using The Data Plane

Angel Najera : Electrical Engineering and Computer Science Summer 2018

The internet essentially functions like a mailing system, with data packets sent across a network of devices. These devices act like the post offices and shipping warehouses from our regular mailing system. Until recently, modifying the way things ran for each device worked in a similar fashion to training a new worker. In our case, it took years for manufacturers to... Read More

Exploring a shallow landsliding event with a multidimensional stability model

Mariel Nelson : geophysics Summer 2018

Shallow landslides are a primary method of sediment transport and a dominant hillslope erosion process in many steep, soil-mantled landscapes. However, testing models that predict shallow landslide size and location is challenging due to a lack of high resolution datasets that map where landslides occurred following major storms. In February 2017, an intense rainfall... Read More

Controlling Antibiotic Production: Regulation of Secondary Metabolism in Streptomyces
