Extinction values towards embedded planets in protoplanetary disks estimated from hydrodynamic simulations
The upcoming new coronographs with deeper contrast limits, together with planned and current high-contrast imaging campaigns will push the detectability limit of protoplanets. These planet-hunting campaigns present a new opportunity to characterize protoplanets and their surrounding environments. However, there are clear uncertainties as to what are the extinction levels at different regions of protoplanetary disks, which will impede our ability to characterize young planets. A correct understa…

The link between $1$-norm approximation and effective Positivstellensatze for the hypercube
The Schmüdgen's Positivstellensatz gives a certificate to verify positivity of a strictly positive polynomial $f$ on a compact, basic, semi-algebraic set $\mathbf{K} \subset \mathbb{R}^n$. A Positivstellensatz of this type is called effective if one may bound the degrees of the polynomials appearing in the certificate in terms of properties of $f$. If $\mathbf{K} = [-1,1]^n$ and $0 < f_\min := \min_{x \in \mathbf{K}} f(x)$, then the degrees of the polynomials appearing in the certificate may b…

Learning control strategy in soft robotics through a set of configuration spaces
The ability of a soft robot to perform specific tasks is determined by its contact configuration, and transitioning between configurations is often necessary to reach a desired position or manipulate an object. Based on this observation, we propose a method for controlling soft robots that involves defining a graph of configuration spaces. Different agents, whether learned or not (convex optimization, expert trajectory, and collision detection), use the structure of the graph to solve the desir…
