lessTitle: The mathematics of the wearable revolution, with applications to circadian rhythms and COVID detection
Speaker: Daniel Forger, PhD, University of Michigan
Special Note: This colloquium will be held at https://northwestern.zoom.us/j/93379493447. The passcode is 685321.
Abstract:
Millions of Americans track their steps, heart rate, and other physiological signals through wearables. This data scale is unprecedented. I will describe several of our apps and ongoing studies, each of which collects wearable and mobile data from thousands of users, even in > 100 countries. This data is so noisy that it often seems unusable in desperate need of new mathematical techniques to extract key signals used in the (ode) mathematical modeling typically done in mathematical biology. I will describe several techniques we have developed to analyze this data and simulate models, including gap orthogonalized least squares, a new ansatz for coupled oscillators, which is similar to the popular ansatz by Ott and Antonsen, but which gives better fits to biological data and a new level-set Kalman Filter that can be used to simulate population densities. My focus application will be determining the phase of circadian rhythms in the real world and the detection of COVID with wearables.

lessA Calculation of the Social Returns to Innovation
What are the social returns to investments in innovation? The disparate spillovers associated with innovation, including imitation, business stealing, and intertemporal spillovers, have made calculations of the social returns difficult. Northwestern Kellogg School of Management’s Benjamin F. Jones will provide an economy-wide calculation that nets out the many spillover margins. He will assess the role of capital investment, diffusion delays, learning-by-doing, productivity mismeasurement, health outcomes, and international spillovers in assessing the average social returns. Overall, estimates suggest that the social returns are very large. Even under conservative assumptions, innovation efforts produce social benefits that are many multiples of the investment costs.

lessTitle: Simple rules for the wrinkle patterns of confined elastic shells
Speaker: Ian Tobasco, PhD, University of Illinois at Chicago
Special Note: This colloquium will be held at https://northwestern.zoom.us/j/91733771698. The passcode is 412369.
Abstract:
Dried fruits wrinkle for the same reason that leaves and flowers do — mechanical instabilities arising from a mismatch in lengths. Can such geometric incompatibilities be used to design and control wrinkle patterns at will? This talk will discuss the possibility of designing wrinkle patterns "in the large" using a recently derived model for the wrinkles of confined elastic shells. After recalling the basic mechanics and introducing our model, we show how it can be solved by hand in many cases to predict the wrinkled topography. Our solution formulas take the form of a few geometric rules, which explain the layout of the wrinkle peaks and troughs. These simple rules reproduce the patterns seen in numerous experiments and simulations, even ones that exhibit a surprising coexistence between orderly wrinkles and a more disordered response. Knowing such rules for wrinkles opens the way towards designer wrinkle patterns, with potential applications ranging from flexible electronics to synthetic skins.

lessHealthcare innovation has taken off despite — and because of — the challenges brought on by the COVID-19 pandemic. Join us as US business editor for The Economist and Visiting Farley Fellow Vijay Vaitheeswaran moderates a panel discussing the latest advances in the field and how the very process of innovation is being reinvented right now. We’ll cover topics in digital health, including telemedicine, "quantified self" devices, consumer empowerment through smart apps, and back-office automation using robotic process automation and AI. We’ll also explore how the pandemic has led to an evolution in process such as open innovation in pharmaceuticals, an industry which has traditionally been secretive about research and development.

lessTitle: Surface Fluctuating Hydrodynamic Methods for Soft Materials with Fluid-Structure Interactions within Curved Fluid Interfaces
Speaker: Paul Atzberger, PhD, UCSB
Special Note: This colloquium will be held online. More details will be available soon.
Abstract:
We introduce surface fluctuating hydrodynamics approaches for investigating transport and fluid-structure interactions within curved fluid interfaces arising in soft materials. We focus particularly on lipid bilayer membranes and
phenomena involving drift-diffusion dynamics of interacting proteins and microstructures. We show how a mesoscale stochastic description of the mechanics can be formulated (SPDEs) accounting for geometric contributions, hydrodynamic coupling, and thermal fluctuations. The underlying stochastic equations (SPDEs) pose challenges for use in practice, including, (i) a need for accurate and stable discretizations of geometric terms and differential operators on the surface, (ii) techniques for hydrodynamics handling surface incompressibility constraints, and (iii) stiffness from rapid time-scales introduced by the thermal fluctuations. We show how practical spectral methods and meshfree computational approaches can be developed for simulations over long spatial-temporal scales. We then present results of investigations of the role of geometry in hydrodynamic transport and the collective drift-diffusion dynamics of inclusions within curved membranes and other systems.------
