Speaker: Tom Dean, Breakthrough Energy
Abstract: Aviation accounts for approximately 3.5% of global anthropogenic climate forcing. Of this, less than half is attributed to the CO2 output from fuel combustion. Nearly half of the total climate impact of aviation can be attributed to contrail cirrus – cirrus clouds that have been seeded by the exhaust plumes of the aircraft – though with considerable uncertainty. Given that only around 2-3% of all flights were are likely responsible for 80% of the global annual contrail climate forcing, a potential contrail mitigation strategy could involve re-routing this subset of flights to minimize the formation of strongly warming contrails. Studies have shown that such strategies would require as little as 0.2% additional fuel burn. Implementing such a strategy requires an accurate ability to forecast contrail impacts, which in turn requires accurate modeling of microphysical atmospheric processes at flight levels. In this talk we will give an overview of contrail modeling and describe the grid-based Contrail Cirrus Prediction model (CoCiP), whose output is designed to be input as a layer in flight planning tools.

lessTitle: Shocks and Caps in Drop Electrohydrodynamics
Speaker: Ehud Yariv, Technion - Israel Institute of Technology
Abstract: The problem of electrohydrodynamic drop deformation is well understood in the case where the external electric field is weak. In one of his many celebrated papers (Proc. R. Soc. A, 291 1425 159-166, 1966), G. I. Taylor worked out a complete theory in this limit, including analytical expressions for the electrohydrodynamic flow engendered within and outside of the drop by the electric field acting on its own induced interfacial charge, and a simple function of the permittivity, conductivity and viscosity drop-to-background ratios discriminating between prolate or oblate deformation. In this talk, we will employ numerical and asymptotic tools to explore the effects of interfacial-charge convection, which were neglected by Taylor but become important at strong electric fields. In particular, we will analyze (in 2D, for simplicity) how Taylor’s fore-aft symmetric solution evolves as the electrical Reynolds number is increased from zero to arbitrarily large values. What we shall find is hinted by the title of the talk. This is joint work with Gunnar G. Peng, Rodolfo Brandão and Ory Schnitzer.

lessTitle: Mathematics of Life Seminar Series: Randomness, Complexity, and the Biological Frontier
Speaker: Pankaj Mehta, Boston University
Abstract: The towering successes of twentieth century theoretical physics were marked by two guiding principles: symmetry and energy functionals (reflecting equilibrium dynamics). Yet how we can exploit these principles to develop a theory of living systems is unclear since the biological world is composed of heterogeneous, interacting components operating out of equilibrium. In this talk, I will argue that one possible strategy for taming biological complexity is to embrace the idea that many biological behaviors we observe are “typical” and can be modeled using random systems that respect biologically-inspired constraints. I will focus on showing how this approach can be used to make close connection with experiments by presenting three vignettes focusing on: (i) theory-inspired techniques for visualizing single-cell transcriptomics data for cellular identity, (ii) understanding how the interplay between cross-feeding and competition shapes microbial ecosystems and (iii) the emergence of chaos in the ecosystems with non-reciprocal interaction.

lessThe Center for Scientific Studies in the Arts is a collaboration between the Art Institute of Chicago and materials science-related departments at Northwestern University to pursue objects-based and objects-inspired scientific research. Materials research benefits ongoing work in conservation, archaeology, art history, and curatorial scholarship.
Learn how the Center uses materials research to care for art objects in sustainable, innovative ways with Maria Kokkori, Senior Scientist in the Center for Scientific Studies in the Arts. She will be in conversation with Corey Byrnes, Northwestern Associate Professor of Chinese Culture and co-founder/co-director of the Environmental Humanities Workshop in Kaplan Humanities Center.
This event is presented by the McCormick School of Engineering and Applied Science in conjunction with exhibition Actions for the Earth: Art, Care & Ecology.

lessTitle: Active Fractal Networks with Stochastic Force Monopoles and Force Dipoles Unravel Subdiffusion of Chromosomal Loci
Speaker: Rony Granek, Ben Gurion University of the Negev
Abstract: Motivated by the well-known fractal packing of chromatin, we study the Rouse-type dynamics of elastic fractal networks with embedded, stochastically driven, active force monopoles and force dipoles that are temporally correlated. We compute, analytically – using a general theoretical framework – and via Langevin dynamics simulations, the mean square displacement (MSD) of a network bead. Following a short time superdiffusive behavior, force monopoles yield anomalous subdiffusion with an exponent identical to that of the thermal system. In contrast, force dipoles do not induce subdiffusion, and the early superdiffusive MSD crosses over to a relatively small, system-size-independent saturation value. In addition, we find that force dipoles may lead to ``crawling" rotational motion of the whole network, reminiscent of that found for triangular micro-swimmers and consistent with general theories of the rotation of deformable bodies. Moreover, force dipoles lead to network collapse beyond a critical force strength, which persists with increasing system size, signifying a true first-order dynamical phase transition. We apply our results to the motion of chromosomal loci in bacteria and yeast cells' chromatin, where anomalous sub-diffusion, MSD∼ t^ν with ν≃ 0.4, were found in both normal and ATP-depleted cells, albeit with different apparent diffusion coefficients. We show that the combination of thermal, monopolar, and dipolar forces in chromatin is typically dominated by the active monopolar and thermal forces, explaining the observed normal cells vs the ATP-depleted cells behavior.
