  • Infants’ sensory-motor cortices undergo microstructural tissue growth coupled with myelination

    Abstract: The establishment of neural circuitry during early infancy is critical for developing visual, auditory, and motor functions. However, how cortical tissue develops postnatally is largely unknown. By combining T1 relaxation time from quantitative MRI and mean diffusivity (MD) from diffusion MRI, we tracked cortical tissue development in infants across three timepoints (newborn, 3 months, and 6 months). […]

  • Statistical Mechanical theory for spatio-temporal evolution of Intra-tumor heterogeneity in cancers: Analysis of Multiregion sequencing data

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    CMSA Interdisciplinary Science Seminar Speaker: Sumit Sinha, Harvard University Title: Statistical Mechanical theory for spatio-temporal evolution of Intra-tumor heterogeneity in cancers: Analysis of Multiregion sequencing data (https://arxiv.org/abs/2202.10595) Abstract: Variations in characteristics from one region (sub-population) to another are commonly observed in complex systems, such as glasses and a collection of cells. Such variations are manifestations of heterogeneity, whose […]

  • Recent Advances on Maximum Flows and Minimum-Cost Flows

    Virtual

    Interdisciplinary Science Seminar Speaker: Yang P. Liu Title: Recent Advances on Maximum Flows and Minimum-Cost Flows Abstract: We survey recent advances on computing flows in graphs, culminating in an almost linear time algorithm for solving minimum-cost flow and several other problems to high accuracy on directed graphs. Along the way, we will discuss intuitions from linear […]

  • Exploring and Exploiting the Universality Phenomena in High-Dimensional Estimation and Learning

    Hybrid

    Interdisciplinary Science Seminar Speaker: Yue M. Lu, Harvard University Title: Exploring and Exploiting the Universality Phenomena in High-Dimensional Estimation and Learning Abstract: Universality is a fascinating high-dimensional phenomenon. It points to the existence of universal laws that govern the macroscopic behavior of wide classes of large and complex systems, despite their differences in microscopic details. The notion of […]

  • Transport in large-N critical Fermi surface

    Virtual

    Speaker: Haoyu Guo (Harvard) Title: Transport in large-N critical Fermi surface Abstract: A Fermi surface coupled to a scalar field can be described in a 1/N expansion by choosing the fermion-scalar Yukawa coupling to be random in the N-dimensional flavor space, but invariant under translations. We compute the conductivity of such a theory in two spatial […]

  • Scalable Dynamic Graph Algorithms

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    CMSA Interdisciplinary Science Seminar Speaker: Quanquan Liu, Northwestern University Title: Scalable Dynamic Graph Algorithms Abstract: The field of dynamic graph algorithms seeks to understand and compute statistics on real-world networks that undergo changes with time. Some of these networks could have up to millions of edge insertions and deletions per second. In light of these […]

    State Diagram of Cancer Cell Unjamming Predicts Metastatic Risk

    https://youtu.be/KmWQPMivxXw Speaker: Josef Käs, Leipzig University Title: State Diagram of Cancer Cell Unjamming Predicts Metastatic Risk Abstract: Distant metastasis is probably the most lethal hallmark of cancer. Due to a lack of suitable markers, cancer cell motility only has a negligible impact on current diagnosis. Based on cell unjamming we derive a cell motility marker for […]

    Gifts from anomalies: new results on quantum critical transport in non- Fermi liquids

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    https://www.youtube.com/watch?v=tCSeu7ykzLs&list=PL0NRmB0fnLJQAnYwkpt9PN2PBKx4rvdup&index=5 Quantum Matter in Mathematics and Physics Seminar Speaker: Zhengyan Darius Shi (MIT) Title: Gifts from anomalies: new results on quantum critical transport in non-Fermi liquids Abstract: Non-Fermi liquid phenomena arise naturally near Landau ordering transitions in metallic systems. Here, we leverage quantum anomalies as a powerful nonperturbative tool to calculate optical transport in these models […]
