NICE model

This lecture tests whether the Nice model can account for the detailed architecture of the Kuiper belt. It contrasts Neptune's behaviour during planetary instability with simpler gradual-migration scenarios. The distribution of distant small bodies provides constraints on the dynamical history of the giant planets.

This seminar explores a version of the Nice model whose starting planetary configuration is produced by migration through a low-viscosity gas disk. Jupiter and Saturn enter a two-to-one resonance with larger eccentricities than in alternative scenarios. The presentation weighs the strengths and limitations of these initial conditions.

Modern versions of the Nice model connect the initial giant-planet orbits to their earlier migration through a gas disk. This lecture examines resonant chains, possible additional ice giants and the effects of planetesimal interactions. Breaking the chain can trigger instability, with simulations testing which configurations reproduce today's planetary orbits.

Low-intensity ultrasound neuromodulation is a rapidly emerging technology due to its non-invasiveness and millimeter-scale precision. Despite numerous experimental settings demonstrating that ultrasonic waves can modulate the neural activity in different brain areas, the interaction between the ultrasonic source and the neuronal tissue is still not fully understood. Several underlying mechanisms have already been proposed to partially explain the interaction between ultrasound and neurons, including mechanosensitivity, flexoelectricity, membrane displacement, and thermodynamic effects.
