These lattice are crucial for lattice-based cryptography. Our construction yields GKP codes with distance $\\sqrt{n/πe}$. This compares favorably with the NTRU-based construction by Conrad et al. that achieves distance $Ω(\\sqrt{n/q}),$ with $n\\le q^2/0.28$. Unlike their codes, our codes do not have secret keys that can be used to speed-up the decoding. However, we present a simple decoding algorithm that, for many parameter choices, experimentally yields decoding results similar to the ones for NTRU-based codes. Using the R-SIS and M-SIS construction, our simple decoding algorithm runs in nearly linear time. Following Conrad, Eisert and Seifert's work, our construction of GKP codes follows directly from an explicit, randomized construction of symplectic lattices with (up to constants $\\approx 1$) minimal distance $(1/σ_{2n})^{1/2n}\\approx \\sqrt{\\frac{n}{πe}}$, where $σ_{2n}$ is the volume of the 2n-dimensional unit ball.

Dataspaces provide the infrastructure necessary to integrate heterogeneous data sources within an organization or ecosystem, enabling seamless data interaction and interoperability. In addition, data spaces strengthen data sovereignty through their decentralized nature, which enables organizations to effectively control and manage their data. However, challenges persist in managing the complexity and dynamic nature of dataspaces, requiring significant resources and technical expertise. The decentralized nature leads to a large and diverse number of stakeholders, who need to agree on the use and scope of a dataspace. Modeling is a common approach to cope with technical complexity and heterogeneous stakeholders. In this paper, we propose a version of SysML and a corresponding method that focus on the modelling of data spaces. We provide a dataspace modelling method to unify the understanding of dataspaces and scope among all stakeholders to simplify the design and development process.","lang":"eng"}],"publication":"2024 IEEE International Conference on Technology Management, Operations and Decisions (ICTMOD)","citation":{"ama":"Kulkarni PJ, Zerbin J, Koldewey C, Bernijazov R, Dumitrescu R.

It serves to compute explanations, or hypotheses, for such missing entailments. While this task has been intensively investigated for perfect data and under classical semantics, less is known about abduction when erroneous data results in inconsistent KBs. In this paper we define a suitable notion of abduction under repair semantics and propose a set of minimality criteria that guides abduction towards `useful' hypotheses. We provide initial complexity results on deciding existence of and verifying abductive solutions with these criteria, under different repair semantics and for the description logics DL-Lite and EL_bot.","lang":"eng"}],"date_created":"2025-08-29T07:58:08Z","external_id":{"arxiv":["2507.21955"]},"department":[{"_id":"574"},{"_id":"888"}],"type":"preprint"},{"department":[{"_id":"888"},{"_id":"574"}],"type":"conference","date_created":"2026-02-05T13:54:08Z","citation":{"chicago":"Haak, Anselm, Patrick Koopmann, Yasir Mahmood, and Anni-Yasmin Turhan. “Why Not?

In this paper, we propose a novel distributed algorithm that enables a group of modules to reconfigure into a rhombus shape, starting from an arbitrary side-connected configuration. It is connectivity-preserving and operates under minimal assumptions: one leader module, common chirality, constant memory per module, and visibility and communication restricted to immediate neighbors. Unlike prior work, which relaxes the original sliding square move-set, our approach uses the unmodified move-set, addressing the additional challenge of handling locked configurations. Our algorithm is sequential in nature and operates with a worst-case time complexity of O(n^2) rounds, which is optimal for sequential algorithms. To improve runtime, we introduce two parallel variants of the algorithm. Both rely on a spanning tree data structure, allowing modules to make decisions based on local connectivity. Our experimental results show a significant speedup for the first variant, and a linear average runtime for the second variant, which is worst-case optimal for parallel algorithms."}],"publication":"Stabilization, Safety, and Security of Distributed Systems","type":"conference","department":[{"_id":"79"}],"date_created":"2025-11-23T21:07:12Z","date_updated":"2026-02-11T08:31:14Z","publication_status":"published","title":"Invited Paper: Distributed Rhombus Formation of Sliding Squares","year":"2025","author":[{"full_name":"Kostitsyna, Irina","first_name":"Irina","last_name":"Kostitsyna"},{"id":"55557","last_name":"Liedtke","first_name":"David Jan","full_name":"Liedtke, David Jan"},{"id":"20792","full_name":"Scheideler, Christian","first_name":"Christian","last_name":"Scheideler"}],"publication_identifier":{"issn":["0302-9743","1611-3349"],"isbn":["9783032111265","9783032111272"]},"doi":"10.1007/978-3-032-11127-2_26","language":[{"iso":"eng"}]},{"user_id":"15578","_id":"64098","language":[{"iso":"eng"}],"date_updated":"2026-02-11T09:11:49Z","status":"public","year":"2025","title":"Reconfiguration and locomotion with joint movements in the amoebot model.
