The latter model multi-polarons, i.e., a fixed number of quantum mechanical electrons moving in a polarizable crystal and interacting with the quantized phonon field generated by the crystal's vibrational modes. Both the electrons and phonons can be confined to suitable open subsets of Euclidean space. We also include possibly very singular magnetic vector potentials and electrostatic potentials. Our Feynman-Kac formulas comprise Fock space operator-valued multiplicative functionals and can be applied to every vector in the underlying Hilbert space. In comparison to the renormalized Nelson model, for which analogous Feynman-Kac formulas are known, the analysis of the creation and annihilation terms in the multiplicative functionals requires novel ideas to overcome difficulties caused by the phonon dispersion relation being constant. Getting these terms under control and generalizing other construction steps so as to cover confined systems are the main achievements of this article.}}, author = {{Hinrichs, Benjamin and Matte, Oliver}}, booktitle = {{arXiv:2403.12147}}, title = {{{Feynman-Kac formulas for semigroups generated by multi-polaron Hamiltonians in magnetic fields and on general domains}}}, year = {{2024}}, } @article{52686, author = {{Ahmed, Qazi Arbab and Wiersema, Tobias and Platzner, Marco}}, issn = {{2509-3428}}, journal = {{Journal of Hardware and Systems Security}}, keywords = {{General Engineering, Energy Engineering and Power Technology}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Post-configuration Activation of Hardware Trojans in FPGAs}}}, doi = {{10.1007/s41635-024-00147-5}}, year = {{2024}}, } @inproceedings{52379, author = {{Hüsing, Sven and Schulte, Carsten and Sparmann, Sören and Bolte, Mario}}, booktitle = {{Proceedings of the 55th ACM Technical Symposium on Computer Science Education V. 1}}, publisher = {{ACM}}, title = {{{Using Worked Examples for Engaging in Epistemic Programming Projects}}}, doi = {{10.1145/3626252.3630961}}, year = {{2024}}, } @article{52726, abstract = {{Heteroclinic structures organize global features of dynamical systems.

To tackle this, we introduce DP-NMT, an open-source framework for carrying out research on privacy-preserving NMT with DP-SGD, bringing together numerous models, datasets, and evaluation metrics in one systematic software package. Our goal is to provide a platform for researchers to advance the development of privacy-preserving NMT systems, keeping the specific details of the DP-SGD algorithm transparent and intuitive to implement. We run a set of experiments on datasets from both general and privacy-related domains to demonstrate our framework in use.

Specifically, the dynamics is described by a second order ODE containing an affine control term. Classically, Pontryagin's maximum principle gives necessary optimality conditions for the optimal control problem. For smooth problems, alternatively, a variational approach based on an augmented objective can be followed. Here, we propose a new Lagrangian approach leading to equivalent necessary optimality conditions in the form of Euler-Lagrange equations. Thus, the differential geometric structure (similar to classical Lagrangian dynamics) can be exploited in the framework of optimal control problems. In particular, the formulation enables the symplectic discretisation of the optimal control problem via variational integrators in a straightforward way.}}, author = {{Leyendecker, Sigrid and Maslovskaya, Sofya and Ober-Blöbaum, Sina and Almagro, Rodrigo T.

To meet these expectations, a short packet length is needed, which makes the first-order Shannon rate an inaccurate performance metric for such communication systems. A more accurate approximation of the achievable rates of finite-block-length (FBL) coding regimes is known as the normal approximation (NA). It is therefore of substantial interest to study the optimization of the FBL rate in multi-user multiple-input multiple-output (MIMO) systems, in which each user may transmit and/or receive multiple data streams. Hence, we formulate a general optimization problem for improving the spectral and energy efficiency of multi-user MIMO-aided ultra-reliable low-latency communication (URLLC) systems, which are assisted by reconfigurable intelligent surfaces (RISs). We show that a RIS is capable of substantially improving the performance of multi-user MIMO-aided URLLC systems. Moreover, the benefits of RIS increase as the packet length and/or the tolerable bit error rate are reduced. This reveals that RISs can be even more beneficial in URLLC systems for improving the FBL rates than in conventional systems approaching Shannon rates.}}, author = {{Soleymani, Mohammad and Santamaria, Ignacio and Jorswieck, Eduard and Schober, Robert and Hanzo, Lajos}}, booktitle = {{arXiv:2402.16434}}, title = {{{Optimization of the Downlink Spectral- and Energy-Efficiency of RIS-aided Multi-user URLLC MIMO Systems}}}, year = {{2024}}, } @inproceedings{53259, author = {{Soleymani, Mohammad and Santamaria, Ignacio and Sezgin, Aydin and Jorswieck, Eduard}}, booktitle = {{2023 IEEE 9th International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP)}}, publisher = {{IEEE}}, title = {{{Maximization of Minimum Rate in MIMO OFDM RIS-Assisted Broadcast Channels}}}, doi = {{10.1109/camsap58249.2023.10403459}}, year = {{2024}}, } @inproceedings{53258, author = {{Soleymani, Mohammad and Santamaria, Ignacio and Jorswieck, Eduard}}, booktitle = {{GLOBECOM 2023 - 2023 IEEE Global Communications Conference}}, publisher = {{IEEE}}, title = {{{NOMA-Based Improper Signaling for MIMO STAR-RIS-Assisted Broadcast Channels with Hardware Impairments}}}, doi = {{10.1109/globecom54140.2023.10437458}}, year = {{2024}}, } @inproceedings{53304, author = {{Kuschel, Maurice and Hasija, Tanuj and Marrinan, Timothy}}, booktitle = {{ICASSP 2024 - 2024 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)}}, publisher = {{IEEE}}, title = {{{Rademacher Complexity Regularization for Correlation-Based Multiview Representation Learning}}}, doi = {{10.1109/icassp48485.2024.10446173}}, year = {{2024}}, } @misc{53374, author = {{De Groote, Carsten}}, title = {{{A Dispersion Algorithm for Robot Swarms Inside Polygonal Boundary Shapes}}}, year = {{2024}}, } @misc{53373, author = {{Doddegowda, Rajesh}}, title = {{{Optimal Drone Strategies For Packet Delivery}}}, year = {{2024}}, } @misc{53372, author = {{Thakur, Heena}}, title = {{{Evaluating the Implications}}}, year = {{2024}}, }
