The Hats Simulator is a lightweight proxy for many intelligence analysis problems, and thus a test environment for analysts' tools. It is a virtual world in which many agents engage in individual and collective activities. Most agents are benign, some intend harm. Agent activities are planned by a generative planner. Playing against the simulator, the job of the analyst is to find harmful agent...

In papers by Wang et al. (1998), Liu et al. (1999), and Liu and Tsay (2003), it was proposed that Arabidopsis thaliana Nitrate Transporter1.1 (AtNRT1.1; CHL1) encodes a dual-affinity nitrate transporter that “plays a major role in high-affinity nitrate uptake.” Here, we evaluate this concept by reexamining the uptake kinetics of Arabidopsis (Arabidopsis thaliana) mutant lines defective in NRT1....

The MYST family of histone acetyltransferases (HATs) plays critical roles in diverse cellular processes, such as the epigenetic regulation of gene expression. Lysine autoacetylation of the MYST HATs has received considerable attention recently. Nonetheless, the mechanism and function of the autoacetylation process are not well defined. To better understand the biochemical mechanism of MYST auto...

Hats. Colorful hats. Stylish hats. Playful hats. A wardrobe often reveals a lot about a person's place in the world. In Jeanne Narum's case, her exquisite taste in hats symbolizes the energy and vitality that she radiates. Indeed, her energy is infectious and is widely known for being the source of an academic pandemic leading to the transformation of undergraduate education in science, technol...
