Spontaneous chiral symmetry breaking in active fluids
Jorn Dunkel

Recent experiments show that bacterial and other active suspensions in confined geometries can self-organize into persistent flow structures that exhibit spontaneously broken mirror symmetry.

Geometry effects on cellular signal propagation
Jingwei Ma

Recent advances in X-ray tomography and high performance computing enable modeling of the spatio-temporal dynamics of signaling pathways within a realistic 3D mammalian cell. We study the process of a chemical signal that is activated at random locations on cell membrane diffuses across cytosol and into nucleus.

Formation of rogue waves in continuum and discrete models: theory and computation
Efstathios G. Charalampidis

In this talk, we will discuss the dynamics of rogue waves in nonlinear Schrodinger (NLS) equations and discrete variants thereof. Initially, we will consider NLS equations with variable coefficients which can be converted into their integrable siblings by utilizing suitable transformations. Then, the Peregrine soliton will be fed to the transformation employed.

Steady-states of rotating stars and galaxies
Allen Wu

The equilibrium shape and density distribution of rotating fluids under self-gravitation is a classical problem in mathematical physics. Early efforts before the twentieth century revealed ellipsoidal solutions with constant density.

Linear stability of planar spiral waves
Ang Li

Planar spiral waves have been observed in many natural systems and also as solutions of reaction-diffusion equation.

Spin lattices of macroscopic wave-driven particles
Pedro J Saenz

We demonstrate the spontaneous emergence of collective behavior in spin lattices of droplets walking on a vibrating fluid surface. Circular wells at the bottom of the fluid bath encourage individual droplets to walk in clockwise or counter-clockwise direction along circular trajectories centered at the lattice sites.

The attenuated geodesic ray transform
Yernat Assylbekov

The attenuated geodesic ray transform is the integration of functions over geodesics with the exponential weight factor. This is the theoretical backbone of medical imaging techniques such as SPECT and Ultrasound Tomography. In applications, we often encounter such transforms acting on tensor fields.
