Complex/Dynamical Systems Seminar
- The Influence of Coupled Wave Networks on the Dynamics of Nonlinear LatticesNonlinear lattice models, which describe the dynamics of spatially discretized systems, are an important class of models for understanding the behavior of solid materials,
- Recent applications of the hybrid particle-ensemble Kalman filter in Lagrangian data assimilationLagrangian data assimilation consists of directly assimilating the positions of (semi-) passive drifters in order to estimate the underlying flow field
- Optimizing flexibility in the collective decisions of honeybeesHoneybees make decisions as a group while searching for a new home site or foraging. The quality of each choice influences the rate at which scout bees recruit others via a waggle dance
- Shattered Time: Can a Time Crystal Survive Quantum Correlations?Time crystals are an exotic new form of matter proposed by Nobel laureate Frank Wilczek in 2012 and demonstrated in lab experiments by two independent groups in the past two years.
- What can you discover about a Dynamical System using a computer?This talk will cover several methods of dynamical system discovery. The first concerns time-delay embedding of observed data, with an in-depth discussion of the continuity
- Control of macroscopic neuronal network activity is optimal at criticalityThere is growing evidence that the cortex operates at a critical state where the strength of excitatory and inhibitory neurons is precisely balanced. Recent research has shown
- Wave initiation thresholds in neural fields: An interface dynamics approachTraveling waves of neural activity have been observed in vitro and in vivo, resulting for instance from sensory inputs at nucleate outward propagating fronts. However,
- Velocity and Vorticity in the Right Human HeartRecent advances in time-resolved 3D cardiac magnetic resonance imaging (4DMRI) have allowed for the 3-dimensional, 3-component characterization of blood flow in the right ventricle (RV) and right atrium
- Investigations of asymptotic models for convection-driven flows in astrophysical and geophysical fluidsGeophysical flows, such as the turbulent motion within the Earth’s liquid iron outer core, are characterized by a wide range of spatial and
- A network approach to cloud organizationClouds are an important component of the climate system that tend to cool the planet by reflecting incoming solar radiation back to space. The representation of shallow clouds and their radiative impact is one
