The objectives of this study were to determine the extent of absorption of functionalized
single-wall carbon nanotubes (SWCNTs) across the gut epithelial cells in Daphnia magna.
Several microscopic techniques were utilized, including micro-Raman spectroscopy, high-resolution
transmission electron microscopy (HRTEM) and selective area diffraction (SAD). In an
effort to examine the...

Pactamycin, a complex aminocyclitol compound produced by Streptomyces pactum, has significant antibiotic, antitumor, and antiplasmodial activity. However, this natural product has not been developed for clinical use due to its high cytotoxicity. Modulation of its biological properties by chemical synthesis has been difficult due to its complex chemical structure. Therefore,...

Chitosan based hemorrhage control dressings provide effective external hemorrhage control while having few side effects. Known residual contaminants present in chitosan formulations include endotoxins and proteins known to stimulate gene expression in the liver. This study investigated gene expression in the liver using rat bio-compatibility models to gain knowledge regarding...

We present a user study to investigate the impact of explanations on non-experts' understanding of reinforcement learning (RL) agents. We investigate both a common RL visualization, saliency maps (the focus of attention), and a more recent explanation type, reward-decomposition bars (predictions of future types of rewards). We designed a 124...
Just as Pirsig’s (Pirsig, R.M. 1974. Zen and the Art of Motorcycle Maintenance. William Morrow and Company, New York. 412pp.) account of his motorcycle adventure explores the dichotomy of holistic and reductionistic philosophies, so too does a short course in chainsaw safety and tree felling incorporate these seemingly disparate viewpoints...
