Recent publications describe profiled single trace side-channel attacks (SCAs) against the DES key-schedule of a “commercially available security controller”. They report a significant reduction of the average remaining entropy of cryptographic k

Phase transitions in quantum matter are related to correlation effects and they can change the ordering of material. Here the authors measure the first-order spatial correlation and the de Broglie wavelength for both thermal and condensed form of a p

Phase transitions are often revealed by a discontinuous behaviour of thermodynamic quantities. Here, the authors study the thermodynamic behaviour of a trapped 2D photon gas, revealing critical behaviour at the phase transition through a cusp singula

We study a relation between Hadamard powers and polynomial kernel perceptrons. The rank of Hadamard powers for the special case of a Boolean matrix and for the generic case of a real matrix is computed explicitly. These results are interpreted in ter

In this article a framework for the generation of a computationally fast surrogate model for district heating networks is presented. An appropriate model is given by in an index-1 hyperbolic, differential algebraic equation quadratic in state, exhibi

We study the optimal control of district heating networks using a reduced order model based on a system theoretic description close to the underlying Euler equations. In the presented scenarios, the central task is to limit the maximal feed-in power

We consider orthogonal transformations of arbitrary square matrices to a form where all diagonal entries are equal. In our main results we treat the simultaneous transformation of two matrices and the symplectic orthogonal transformation of one matri
This paper considers balanced truncation of discrete-time Hankel $k$-positive systems, characterized by Hankel matrices whose minors up to order k are nonnegative. Our main result shows that if the truncated system has order $k$ or less, then it is H

The stochastic $H^\infty $ -norm is defined as the $L^{2}$ -induced norm of the input-output operator of a stochastic linear system. Like the deterministic $H^\infty $ -norm it is characterized by a version of the bounded real lemma, but without a fr
