Lux ad cilium: investigating the role of intraciliary calcium and fluid flow in left-right development |
Speaker Bio: Dr. Lydia Djenoune is a Postdoctoral Fellow in the Yuan lab. After completing her Master of Genetics from Paris Diderot University, she received her PhD from the French National Museum of Natural History under the mentorships of Dr. Claire Wyart and Prof. Hervé Tostivint studying the molecular and morphological heterogeneity of the cerebrospinal fluid-contacting neurons and the role of the polycystin channel Pkd2l1 in zebrafish spinal cord. For her postdoctoral training, she first joined the group of Prof. Iain Drummond at The Massachusetts General Hospital to probe the role of calcium signaling in kidney glomerular morphogenesis. In the Yuan lab, Lydia is investigating the role of intra-ciliary calcium and mechanosensation in cardiac left-right development. |

Toward Factuality in Information Access: Event-Centric Multimodal Knowledge Acquisition |
Abstract: Traditionally, multimodal factual knowledge extraction has been entity-centric with a focus on concrete concepts, but lacks ability to understand abstract semantics. However, such event-centric semantics are the core knowledge communicated, regardless whether in the form of text, images, videos, or other data modalities. At the core of my research in Multimodal Information Extraction (IE) is to bring such deep semantic understanding ability to the multimodal world. My work opens up a new research direction Event-Centric Multimodal Knowledge Acquisition to transform traditional entity-centric single-modal knowledge into event-centric multi-modal knowledge. Such a transformation poses two significant challenges: (1) understanding multimodal semantic structures that are abstract: I will present my solution of zero-shot cross-modal transfer, which supports zero-shot multimodal event extraction for the first time; (2) understanding long-horizon temporal dynamics: I will introduce Event Graph Model, which empowers machines to capture complex timelines with multiple alternative outcomes. I will also show its positive results on long-standing open problems, such as timeline generation, meeting summarization, and question answering. I will then lay out how I plan to promote factuality and truthfulness in information access, through a factual knowledge graph view that is easily explainable, highly compositional, and capable of long-horizon reasoning. Speaker Bio: Manling Li is a CS Ph.D. candidate at University of Illinois Urbana-Champaign. Her work on multimodal knowledge extraction won the ACL'20 Best Demo Paper Award, and the work on scientific information extraction from COVID literature won NAACL'21 Best Demo Paper Award. She was a recipient of Microsoft Research PhD Fellowship in 2021. She was selected as a DARPA Riser in 2022, an EE CS Rising Star in 2022, and a Mavis Future Faculty Fellow in 2021. She led 19 students to develop the UIUC information extraction system and ranked first in DARPA AIDA TA1 evaluations. Additional information is available at https://limanling.github.io. |

Is the extensive mutual information model a QFT? |
I will introduce the so-called extensive mutual information model (EMI), which is the unique solution to the known axioms of the ground state mutual information of a CFT, when one imposes extensivity on its arguments. Using various results concerning the mutual information of largely separated regions, I will then show that the EMI cannot describe the ground state mutual information of a CFT in dimensions greater than two. This result suggests that the set of known axioms of the mutual information might be incomplete. |

The Effects of Spaceflight on the Human Brain and Behavior |
Emerging plans for travel to Mars and other deep space destinations make it critical for us to understand how spaceflight affects the human brain and behavior. Moreover, studying adaptation to the microgravity environment provides insight into how the central nervous system responds to an environment for which it has not evolved. I will share findings from my work indicating that the spaceflight environment induces adverse effects on the brain, including intracranial fluid shifts, gray matter changes, and white matter declines. I will also present evidence that adaptive processes co-occur with these brain position and intracranial fluid shifts. I will close with recommendations for future research |

Horocycle flow on the moduli space of translation surfaces |
I will discuss the dynamics of the horocycle slow on a stratum of translation surfaces (which is an invariant subvariety of the bundle Omega M_g of holomorphic one forms over the moduli space of genus g Riemann surfaces). This flow can be defined as the action of upper triangular matrices with eigenvalue 1, acting linearly on flat charts. Work of Ratner on unipotent flows on homogeneous spaces leads to the question of whether the orbit-closures and invariant measures for this action can be meaningfully classified. I will quickly survey both positive and negative results in this direction. The talk will be based on joint work with Bainbridge, Chaika, Smillie, and Ygouf (in various combinations). |

Are certain arithmetic questions optimization problems in disguise? |
Given a natural number, how many divisors does it have? This is an example of an arithmetic function. In this talk, we shall discuss a conjectural characterization of a class of arithmetic functions, in terms of solutions to certain explicit optimization problems. We shall focus on the case when the arithmetic function is the so-called L-function coefficients of an elliptic curve over the rational numbers -- the involved terms shall be explained. But wait a moment, how could arithmetic and optimization have anything to do with each other? Joint works in progress with Henry Cohen, Bogdan Stoica, Alexandru Zaharescu, Xiao Zhong. |

Recovering Structured Matrices |
A fundamental paradigm in data science involves the recovery of a structured object from certain types of observations of it. This is an example of what is known as an inverse problem. In this talk, we will consider the problem of recovering a matrix from low-dimensional projections. We will motivate the problem by discussing applications in matrix completion, graph learning, phase retrieval, and covariance sketching. We will then discuss how we can take advantage of matrix structure to yield efficient algorithms for the problem. |

Combinatorics of forest polynomials |
I will introduce a new basis for the ring of polynomials that we call forest polynomials. This basis is particularly friendly toward reduction modulo the ideal of quasisymmetric polynomials, and as such allows us to describe the cohomology class of the permutahedral variety in terms of Schubert classes via a parking procedure. I will also use this perspective to motivate a multivariate analogue of mixed Eulerian numbers. Joint work with Philippe Nadeau (CNRS & Univ. Lyon 1). |

Homology cobordism and the geometry of hyperbolic three-manifolds |

A General Theory of Mechanical Screening: From Granular Matter to tissue mechanics |
Holes in elastic metamaterials, defects in 2D curved crystals, localized plastic deformations in amorphous matter and T1 transitions in epithelial tissue, are typical realizations of stress-relaxation mechanisms in different solid-like structures, interpreted as mechanical screening. Correspondingly, understanding the emergent hole patterns, defects structure, and mechanical response in these systems remains a formidable task. While screening theories are well established in other fields of physics, e.g. electrostatics, a unifying theory of mechanical screening applicable to crystalline, amorphous, and living-cellular matter, is still lacking. In this talk I will present a general mechanical screening theory that generalizes classical theories of solids, and introduces new moduli that are missing from the classical theories. Contrary to its electrostatic analog, the screening theory in solids is richer even in the linear case, with multiple screening regimes, predicting qualitatively new mechanical responses. Specifically, we predict a regime of screening that is mechanically similar to the celebrated Hexatic phase, in disordered matter. The theory is tested in different physical systems, among which are disordered granular solids and models of epithelial tissue. Experiments and numeric simulations in granular, glass, and tissue models uncover a mechanical response that strictly deviate from classical elasticity, and is in full agreement with the theory. Finally I will discuss the relevance of the theory to other systems such as wrinkled sheets, disordered metamaterials, and most importantly to 3D solids and the potential for a new Hexatic-like state in three-dimensional matter. |
