Divertor detachment and reattachment with mixed impurity seeding on ASDEX Upgrade
Using newly developed spectroscopic models to measure the divertor concentration of Ne and Ar, it is shown that the experimental detachment threshold on ASDEX Upgrade with Ar-only and mixtures of Ar+N or Ne+N scales as expected in comparison with an analyt ...
IOP Publishing Ltd2023A Trojan Horse across the Channel: On the circulation of Vincenzio Viviani’s divinatio through his correspondence with Robert Southwell
Simon François Dumas Primbault
Self-proclaimed Galileo’s last disciple, Vincenzio Viviani (1622-1703) strove all his life to become a renowned mathematician. Extolling the supposed purity of Euclid’s geometry, he sought to recover the lost knowledge of the Ancients, and fashioned himsel ...
2021Modeling of TAE mode excitation with an antenna in realistic X-point geometry
Experimentally, it is observed that Toroidal Alfven Eigenmodes (TAEs) are difficult to excite with an external antenna when the plasma is in X-point geometry. Here, the effect of the X-point geometry on the efficiency of the TAE excitation with the externa ...
AMER INST PHYSICS2020Last Heir or First Engineer? An Intellectual Portrait of Vincenzio Viviani through his Working Papers
Simon François Dumas Primbault
Self-proclaimed Galileo’s ultimo discepolo, Vincenzio Viviani (1622-1703) strove all his life to become a renowned mathematician. Extolling the supposed purity of Euclid’s geometry, he sought to recover the lost knowledge of the Ancients, and fashioned him ...
2020An Improved Analysis of Local Search for Max-Sum Diversification
Friedrich Eisenbrand, Rico Zenklusen, Alfonso Bolívar Cevallos Manzano
We present new techniques to analyze natural local search algorithms for several variants of the max-sum diversification problem which, in its most basic form, is as follows: given an n-point set X subset of R-d and an integer k, select k points in X so th ...
INFORMS2019Dubrovin'S Superpotential As A Global Spectral Curve
We apply the spectral curve topological recursion to Dubrovin's universal Landau-Ginzburg superpotential associated to a semi-simple point of any conformal Frobenius manifold. We show that under some conditions the expansion of the correlation differential ...
CAMBRIDGE UNIV PRESS2019Adversarially Robust Optimization with Gaussian Processes
Volkan Cevher, Jonathan Mark Scarlett, Ilija Bogunovic
In this paper, we consider the problem of Gaussian process (GP) optimization with an added robustness requirement: The returned point may be perturbed by an adversary, and we require the function value to remain as high as possible even after this perturba ...

NEURAL INFORMATION PROCESSING SYSTEMS (NIPS)2018On the existence of ordinary triangles
Sebastian Urban Stich, Radoslav Fulek, Márton Naszódi
Let P be a finite point set in the plane. A \emph{c-ordinary triangle} in P is a subset of P consisting of three non-collinear points such that each of the three lines determined by the three points contains at most c points of P. Motivated by a question o ...
