SUMMARY:Workshop / Seminar:Frobenius Identities in Combinatorics (Combinatorics seminar)
DESCRIPTION:Several recent proofs of unimodality theorems in combinatorics rely on unexpected identities satisfied by the volume map on combinatorially defined algebras over fields of characteristic p. The proof of unimodality for the h-vector of simplicial spheres by Papadakis–Petrotou and for the h^*-vector of IDP and Gorenstein lattice polytopes by Adiprasito–Papadakis–Petrotou both fit into this framework. In this talk\, we reinterpret the volume map from the perspective of commutative algebra and explain the origin of these identities. This viewpoint yields short proofs and suggests new research directions. This is joint work with Adiprasito\, Oba\, Papadakis\, and Petrotou.

SUMMARY:Presentation:The Origin of Metals in Galaxy Clusters - Characterizing the Early Enrichment Population
DESCRIPTION:Metals (anything heavier than Helium) are made by stars\, but when and where those stars existed in the Universe is an outstanding problem. X-ray observations show that the hot\, X-ray emitting gas surrounding galaxy clusters\, the intracluster medium (ICM)\, has a nearly universal metallicity of ZICM ≈ 0.4Z⊙. This metallicity is largely independent of stellar fraction\, M∗/Mgas\, and exceeds what is expected from present-day stellar populations under standard initial mass functions (IMFs). This discrepancy is known as the missing metal conundrum. Many theories have been posed to explain this mismatch\, but fault has been found to each when compared with observations. The primary remaining theory yet to be disproved is the existence of an Early Enrichment Population (EEP) - a predominantly high-mass stellar population at z ∼ 10 − 6 that enriched the ICM while leaving a minimal surviving population. In this dissertation\, I develop and test a quantitative framework for the EEP by combining detailed X-ray measurements\, chemical evolution models\, and constraints from supernovae and galaxy luminosity functions. I do this through a homogeneous study of 26 galaxy groups and clusters using archival XMM-Newton data\, measuring radial metallicity profiles and the deriving the relation between ZICM and M∗/Mgas. With this I show that an additional metal component\, ZEEP is required even when updated yields\, remnants\, and non closed-box behavior in groups are taken into account when deriving the contribution from the visible stellar populations\, Z∗. I then construct theoretical models for the EEP\, exploring a range of IMFs and using Type Ia supernovae (SNe Ia) rates to identify IMFs that reproduce both the required metal yield and present-day observables. I further constrain the low-mass end of the EEP IMF by requiring that the residual light from long-lived EEP stars not exceed the observed luminosity of dwarf elliptical galaxies that dominate the low-luminosity component of cluster luminosity functions. Together\, these results provide the first observationally anchored\, testable constraints on the EEP and its IMF\, and establish concrete predictions for high-redshift supernovae and dwarf galaxy light that can be probed with current and future telescopes such as the James Webb Space Telescope.

SUMMARY:Lecture / Discussion:AIM Seminar:  Sensitivity limits from the geometry of nonequilibirum response
DESCRIPTION:Abstract:  Many biophysical processes can be accurately modeled as a system stochastically exploring a discrete and connected network of possible states. Probability distributions over this space are not only subject to the system's intrinsic noisy dynamics\, but may also be influenced by externally imposed perturbations. While results such as the Fluctuation-Dissipation Theorem allow for a precise understanding of how such perturbations may affect observable quantities on the system\, these only properly function at equilibrium. Here\, we explore the case of perturbations on nonequilibrium stochastic systems and derive a new response formula based on the Matrix-Tree Theorem approach. In particular\, we derive the tightest possible linear bounds to sensitivity in arbitrary observables based on only the topology of the state network. These bounds stem from achetypical primitive models we call \"uniquely constructable sets\" that dictate the system properties under extreme conditions. As an exploratory example\, we investigate a model of a macromolecule with three ligand binding sites to showcase how the uniquely constructable sets can be used to find all possible variations that are capable of maximizing the sensitivity of the number of bound sites relative to the external ligand concentration.\n\nContact:  AIM Seminar Organizers

SUMMARY:Lecture / Discussion:Department Colloquium: Dilip Ninan (Tufts)
DESCRIPTION:Title: The Puzzle of Known Violation\n\nAbstract: \nSuppose it is true that I should sell all my possessions and give the money to the poor. Then it would seem to follow that I should sell all my possessions. This piece of reasoning is underwritten by a principle known as Inheritance: if p entails q\, then \"should p\" entails \"should q\". But Åqvist (1967) pointed out some apparent counterexamples to Inheritance: \"Max should have known he was breaking a rule\" does not entail \"Max should have been breaking a rule\" even though \"Max knew he was breaking a rule\" entails \"Max was breaking a rule\". I argue that Åqvist's observation is an instance of something more general: for many p and q where p entails and presupposes q\, \"should p\" does not entail \"should q\". I sketch a semantics that accommodates this fact while still preserving the truth of many instances of Inheritance. Finally\, I show that our discussion has consequences for a rather different debate in philosophy\, as it seems to undermine a recent argument against the knowledge account of assertion.\n\n\nResearch/Areas of Interest\nPhilosophy of Language\, Metaphysics\, Philosophy of Mind\n\nEducation\nPhD in Philosophy\, Massachusetts Institute of Technology\, Cambridge\, United States\, 2008\nMSc in Economic and Social History\, University of Oxford\, Oxford\, United Kingdom\, 2002\nBPhil in Philosophy\, University of Oxford\, Oxford\, United Kingdom\, 2001\nBA in Philosophy\, University of Western Ontario\, London\, Canada\, 1999\n\nBiography\nDilip Ninan received his Ph.D. from MIT\, B.Phil. from Oxford University\, and B.A. from the University of Western Ontario.

SUMMARY:Lecture / Discussion:Sociocultural Anthropology Colloquium | “Working the Loops: Co-Constructing Painful Bodies and Categories in Thailand”
DESCRIPTION:“In the U.S.\, patients and practitioners usually imagine that pain is a thing\, that one’s approach to it may change how one copes with it\, but not the pain itself. This is connected to medicine’s insistence on a ‘view from nowhere\,’ perceiving nature without changing it. Meanwhile\, STS scholars have long taught us about looping effects between categories and the world. In this talk\, I present ethnography on painful bodies in Thailand\, where the idea of looping between category and reality is part of everyday cosmology. I share about: doctors who worry that giving ‘chronic pain’ a diagnostic code will bring it into being\; monks who suspect that pain equals fear-of-death\, leading them to induce near-death experiences\; anesthesiologists with evidence that poor Thai patients need less anesthesia during surgery (because lifelong pain-as-necessity crafts brains with low-pain neurotransmitter profiles?)\; and patients who dream that pain is a reincarnated being and awake with different pain. Through this ontological adventure\, I ask whether STS might benefit not just from ethically identifying co-constructionism as a sociohistorical force\, but also from examining times and places where people work co-constructionism to their advantage as a matter of course.”\n\nScott Stonington is a medical and cultural anthropologist\, and an internal medicine physician. His research broadly addresses the globalization of biomedical ethics and expertise. His first project in this area focused on decision-making at the end of life in Thailand\, where individuals face a complex combination of ethical frameworks generated by high-tech medical care\, human-rights politics\, and the metaphysical demands of dying. Dr. Stonington spent two years accompanying Thai elders at their deathbeds\, documenting their children’s attempts to pay back their “debt of life” via intensive medical care\, as well as the ensuing “spirit ambulance\,” a rush to get patients on life-support home at the last possible moment to orchestrate the final breath in a spiritually advantageous place. Dr. Stonington’s second project in this area focuses on global debates over the use of opiates for pain management. He spent a year accompanying patients in severe pain in Northern Thailand as they navigated their suffering within a fraught ethical environment\, from Thailand’s brutal drug war\, to its Buddhist-based value for pain as a spiritual path\, to a broader global ambivalence about how best to treat pain. Dr. Stonington’s secondary research agenda addresses medical epistemology in the U.S.\, specifically how health practitioners decide what constitutes true and/or useful knowledge and how this affects patients. This work grows out of his ongoing practice as an Internal Medicine physician\, both in the hospital and in primary care.
