Positivity of hexagon perturbation theory
Journal of High Energy Physics, 2018 The hexagon-form-factor program was proposed as a way to compute three-and higher-point correlation functions in N = 4 $$ \mathcal{N}=4 $$ super-symmetric Yang-Mills theory and in the dual AdS5×S5 superstring theory, by exploiting the integrability of ...

A tight colored Tverberg theorem for maps to manifolds (extended abstract) [PDF]
Discrete Mathematics & Theoretical Computer Science, 2011 Any continuous map of an $N$-dimensional simplex $Δ _N$ with colored vertices to a $d$-dimensional manifold $M$ must map $r$ points from disjoint rainbow faces of $Δ _N$ to the same point in $M$, assuming that $N≥(r-1)(d+1)$, no $r$ vertices of $Δ _N ...

Frontiers in Applied Mathematics and Statistics, 2021 This work introduces a methodology for studying synchronization in adaptive networks with heterogeneous plasticity (adaptation) rules. As a paradigmatic model, we consider a network of adaptively coupled phase oscillators with distance-dependent ...

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We study eigenvalue problems for the de Rham complex on varying three‐dimensional domains. Our analysis includes the Helmholtz equation as well as the Maxwell system with mixed boundary conditions and non‐constant coefficients. We provide Hadamard‐type formulas for the shape derivatives under weak regularity assumptions on the domain and its ...

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.Zusammenfassung Hintergrund Realistische Trainingsmodelle sind essenziell, um Ärztinnen und Ärzte in klinischen Prozeduren zu schulen. In dieser Studie wurde untersucht, ob ein kostengünstiges, selbst generiertes 3D‐gedrucktes Hautmodell Früchten und Schaumstoffmodellen beim Erlernen von Hautstanzen überlegen ist.

Validation of machine learning based scenario generators
Journal of Risk and Insurance, EarlyView.Abstract Machine learning (ML) methods are becoming increasingly important for designing economic scenario generators for internal models. Validating data‐driven models requires different methods than validating classical, theory‐based models. We discuss two novel aspects of such validation: first, checking the multivariate distribution of risk factors,
