Thursday, January 15 | Bits & Bytes Hosts Will Leeson on "Leveraging SMT Solver Instability"
|
3:30-4:30 pm • Anderson 329 • Computer Science
Bits & Bytes Hosts Will Leeson on "Leveraging SMT Solver Instability" Abstract: The Boolean satisfiability (SAT) problem is a longstanding and well-studied problem in computer science. Given a formula consisting of boolean values, variables, and operators, the problem asks whether there is some assignment to the variables in the formula such that the formula evaluates to true.

Friday, January 16 | Geology Seminar: Tony Runkel
|
3:30-4:30 pm • Anderson 129
Tony Runkel - Lead Geologist, Minnesota Geological Survey "The Challenge of Implementing Geoscience-Guided Groundwater Protection Rules in Minnesota’s Vulnerable Karstic Region" Agricultural activities across southeast Minnesota’s karstic terrain have resulted in extensive areas where greater than ten percent of wells are above the drinking water standard of 10 mg/l, leading to several policy and management strategies to mitigate the problem. Many of these strategies are relatively routine and have been in practice for many years, such as setbacks of manure storage and application from karst features. More recently, Minnesota’s Groundwater Protection Rule (GPR) was established, with the purpose of minimizing nitrogen fertilizer sources of nitrate pollution. Learn more here.

- Biology Seminar: Sebastian Schreiber, Professor of Evolution and Ecology, University of California, Davis, “When do environmental rhythms alter ecological outcomes?” - Olin 141, 3:30-4:30 pm
We live in a world where environmental conditions are constantly changing: some years are warmer than others, some days are wetter than other days. It is well-known that this environmental variation can result in population declines or mediate coexistence between competing species. However, it is less well-known how the rhythm of this environmental variation impacts ecological outcomes. In this talk, Professor Schreiber will show that the temporal structure of environmental fluctuations—not just their magnitude—can fundamentally alter ecological outcomes. For competing species, positive autocorrelation in environmental conditions can promote coexistence while negative autocorrelations can generate alternative stable states. For structured populations, the tempo and mode of environmental change (random versus periodic) can determine whether populations persist or go extinct. Together, these results suggest that understanding when and how environments fluctuate may be just as important as understanding that they fluctuate.

- Physics Table - Check Radiations Newsletter for location, noon - 1 pm
If you have any sort of interest in Physics or Astronomy, come join other folks who are, and enjoy a community lunch! We usually gather at the LDC at noon each Tuesday (check our newsletter Radiations for any exceptions). If you're off board or on a limited plan, let the cashier know you're there for Physics Table and we'll treat you to lunch!
- Math/Stats Colloquium: Sebastian Schreiber, University of California, Davis - CMC 206, 4-5 pm
Diversity or Collapse? How Invasion Graphs Predict the Fate of Ecological Communities Abstract: Why do some sets of species coexist while others don't? Why does introducing one species increase community diversity while another triggers a collapse? How can environmental fluctuations promote coexistence when it's impossible in any constant environment? Learn more here

Wednesday, January 14 | Immigration 101: Overview of US Immigration Policy
|
6-7 pm • Hasenstab 002 • CCCE
Want to know more about immigration policy in the US and how it’s playing out in communities like this one? Come hear a brief presentation and help us decide what questions to ask a panel of immigration advocates who will be speaking at a follow up session later this term during Week 7. This event is open to the entire Carleton community.
This is the first event of a two part series working to raise campus awareness on immigration and ICE incidents in Northfield. The second event will have a panel of local and state wide immigration advocates to talk about the ecosystem of support for immigrants in our community and state. Email Lily with any questions, dinner provided, RSVP here.

Library support course requests for Winter term are now being accepted. Please get in touch if you would like a library instruction component for your class this term! This could be a traditional librarian class visit, a custom course guide featuring selected resources, or you may just want to highlight the library consultation services available to your students. Of course library support doesn’t need to look the same for every class. Have an idea? Just reach out! Dates are filling quickly.
Events
Three College Librarian candidate interviews will take during weeks 2 and 3 this term. Public talks will be held in the Gould Library Athenaeum during Common Time (Noon-1 pm) on January 13th,15th, and 20th. All are welcome to attend.
Resources updates
 LibKey Nomad is a tool that seamlessly connects you to Carleton Library subscriptions making it easy to access a PDF with the click of a button directly from the places you already search like PubMed and many publisher websites. Learn more and download the browser add-on to get started today!

Alex Knodell, professor of classics and director of archaeology, published an article with colleagues in the journal Hesperia. At 99 pages, this is the most substantial publication of the Small Cycladic Islands Project yet, detailing archaeological survey work on 14 currently uninhabited islands in the western Cyclades. New discoveries shed light on settlement patterns, subsistence, mineral extraction, and military activity across the archipelago. Several Carleton students contributed to this work as part of an international team.
Kaz Skubi ’11, assistant professor of Chemistry, was awarded funding from the provost’s Hewlett Mellon endowment for his work on “Controlling the Selectivity of Radical Reactions Enabled by Visible Light Photocatalysis.”
Cherlon Ussery, professor of cognitive science and linguistics, was awarded support from the Smith fund for her work on “Building Capacity at MMUF Liberal Arts Institutions.”
Matt Whited, professor of chemistry, was awarded funding for travel to Germany to collaborate with a colleague on new cooperative catalytic systems with earth-abundant metals.
Sarah Kennedy, assistant professor of archaeology and Latin American studies, was awarded funding from the provost’s Hewlett Mellon endowment and a Class of ’49 Fellowship to support her work on “Incan Expansion and Native Resistance in the Peruvian Altiplano.”
