And when I want to present my work to other scientists or to a wider audience, I use these same tools, infused with a bit more artistic flair. In my own research in computational biology and drug design, I use these tools every day without thinking twice. We load a protein structure, measure distances and angles at coordination sites, look for neighboring amino acids and try to reconcile mutational data, color by surface charge or hydrophobicity to understand how this protein interacts with others, and so on. They allow us to pose structural questions on the fly and answer them interactively. PSVMOD1.0 is a compilation of globally distributed palaeodirectional data from archaeomagnetic artefacts, lava flows, and lake sediments at 24 sites. I feel comfortable talking to her about all my mental health and medical needs. If you donвЂ™t know which domain youвЂ™re in, try CC first.

Residency: Scripps Mercy Hospital Transitional Internship (2012) CA. You can login with your complete email address. Today, we can head over to one of the worldwide Protein Data Bank sites ( ) and instantly view more than 170,000 biomolecular structures using highly sophisticated graphics tools that are available, amazingly, directly in a web browser or on your phone. The impact of these visual tools is hard to measure, since they are so ingrained in every aspect of our work, both in research and in its dissemination. My time at this internship helped me to gain a better understanding of my own artwork, where the goal is more circumscribed: to create imagery as a tool for science. Consequently, fine artists need to create entire worlds from scratch. As they create work that speaks to their audiences, they are limited only by imagination and the technicalities and seductions of their chosen media. Scientists work within very tight constraints: experiments must probe the nature of the world and must be reproducible hypotheses must account for observations in a logical way and most importantly, scientists must then devise new ways to test and possibly destroy these hypotheses with further experimentation. The experience was daunting, and in many ways, I came away with the impression that an artistвЂ™s task is infinitely more difficult than the work we face as scientists. Once a year, this program tosses together six scientists and six artists for a month and provides them with the chance to create together. Our findings demonstrate that sediment supply is encoded in the bankfull hydraulic geometry of gravel bedded channels through its control on bed surface grain size.At a recent summer internship hosted by the Djerassi Resident Artists Program, I had the opportunity to watch several fine artists at work 1.

Our analysis reveals a decrease in bed surface armoring with increasing П„ b f * / П„ c *, suggesting channels accommodate changes in sediment supply through adjustments in bed surface grain size, as also shown through numerical modeling. Supporting our hypothesis, we find a significant correlation between upstream erosion rate and local П„ b f * / П„ c * at sites where this comparison is possible. Since it has already been more than 10 years since my time at Scripps, the specific. This pattern parallels patterns in erosion rates (and hence sediment supplies). Janda at The Scripps Research Institute in the U.S., for about a year.

We find that П„ b f * / П„ c * is significantly higher in West Coast river reaches (2.35, n = 96) than in river reaches elsewhere on the continent (1.03, n = 245). We use a database of >300 gravel-bedded rivers and >600 10Be-derived erosion rates from across North America to explore the hypothesis that sediment supply drives the magnitude of bankfull shear stress relative to the critical stress required to mobilize the median bed surface grain size ( П„ b f * / П„ c *). However, not all natural gravel channels actually conform to this simple relationship some channels maintain bankfull stresses far in excess of the critical stress required to initiate sediment transport. Because this observation is common and is supported by theory, the coincidence of bankfull flow and the incipient motion of D 50 has become a commonly used assumption.

In many gravel-bedded rivers, floods that fill the channel banks create just enough shear stress to move the median-sized gravel particles on the bed surface ( D 50).
