SUMMARY:Lecture / Discussion:Gomberg Lecture - \"Structural Biology of Bacterial Antiphage Defense\"
DESCRIPTION:The lecture will begin by describing research on CRISPR systems containing single subunit Cas proteins and multi-subunit Cascade complexes with the emphasis on assembly\, target recognition\, cleavage autoimmunity and the impact of anti-CRIPR proteins in suppressing the CRISPR-Cas surveillance pathway. The lecture will next focus on multi-subunit type Ill CRISPR Csm complexes outlining mechanisms underlying target RNA binding and cleavage\, as well as cyclic oligoadenylate (cOA) second messenger formation. Next\, the lecture will address mechanistic insights into cOA-mediated activation of CARF­effector cassettes with the emphasis on effectors that are nucleases\, transmembrane domains\, deaminases and NADases\, that trigger abortive infection. The lecture will end with a mechanistic description on some examples of recently identified bacterial systems involved in antiphage defense.

SUMMARY:Presentation:Linguistics Senior Capstone Presentations
DESCRIPTION:Talks will take place in Lorch 471 and virtually (umich.zoom.us/j/6624396919)\n\nStudents will be presenting in small groups on their original research proposals.  Topics include the following:\n\n(1) A corpus study on the role of the sonority hierarchy in consonant cluster mispronunciations in English and Thai-speaking children\;\n\n(2) A combined corpus / experimental study on the effects of screen time exposure in Mainstream American English (MAE) on African-American English (AAE)-speaking toddlers' phonology\;\n\n(3) A longitudinal experimental study on vocabulary regression in school-age heritage speakers of Spanish attending English-language schools\;\n\n(4) An experimental study on the extent to which bilinguals of morphophonologically similar (Spanish-Portuguese) and dissimilar (Spanish-German) languages depend on the lexical constraint of mutual exclusivity across the developmental trajectory\;\n\n(5) A corpus study on the acquisition of grammatical gender among bilingual speakers of languages with differing gender systems (French\, Russian)\;\n\n(6) An experimental study on the acquisition of syntactic and lexical reflexivity in bilingual (Spanish-English) and monolingual children.

SUMMARY:Workshop / Seminar:Polypositroids
DESCRIPTION:To any matroid $M$\, one can associate a matroid polytope $P_M$. It is well-known that these matroid polytopes arise from generalized permutohedra. In 2020\, Lam and Postnikov observed that a matroid $M$ is a positroid iff the matroid polytope $P_M$ is an alcoved polytope. This motivated the definition of a polypositroid\, a polytope which is both a generalized permutohedra and an alcoved polytope. In this talk\, we'll define and explore polypositroids with an eye towards understanding the cone of polypositroids in relation to the cone of generalized permutohedra and the cone of alcoved polytopes.

SUMMARY:Other:Seed Library Kickoff
DESCRIPTION:Come celebrate the kickoff of our seed library on Earth Day! \n\nCreate cyanotype prints and artwork\, make a seed dumpling\, connect with student sustainability groups\, and share seed stories in the Shapiro Gallery (Clark Commons\, 3rd floor).\n\nCheck out free native Michigan plant and regionally-grown vegetable seed varieties from the Design-o-matic vending machine near the Design Lab (1st floor Shapiro Library). \n\nAs always\, our events are open to the public.

SUMMARY:Workshop / Seminar:GLNT: Vanishing of Selmer groups for Siegel modular forms
DESCRIPTION:Let π be a cuspidal automorphic representation of Sp_2n over Q which is holomorphic discrete series at infinity\, and χ a Dirichlet character. Then one can attach to π an orthogonal p-adic Galois representation ρ of dimension 2n+1. Assume ρ is irreducible\, that π is ordinary at p\, and that p does not divide the conductor of χ. I will describe work in progress which aims to prove that the Bloch--Kato Selmer group attached to the twist of ρ by χ vanishes\, under some mild ramification assumptions on π\; this is what is predicted by the Bloch--Kato conjectures.\n\nThe proof uses \"ramified Eisenstein congruences\" by constructing p-adic families of Siegel cusp forms degenerating to Klingen Eisenstein series of nonclassical weight\, and using these families to construct ramified Galois cohomology classes for the Tate dual of the twist of ρ by χ.
