In this work, we develop a systematic approach for constructing and analyzing <jats:italic>χ</jats:italic>-colorable graph states, deriving explicit closed-form expressions for arbitrary <jats:italic>χ</jats:italic>. For a broad family of two- and three-colorable graph states, the representations obtained using only local operations require a minimal number of terms in the <jats:italic>Z</jats:italic>-eigenbasis. We prove that every two-colorable graph state is local Clifford (LC) equivalent to a state expressible as a summation of rows of an orthogonal array (OA). For graph states with <jats:italic>χ</jats:italic> &gt; 2, we show that they are LC-equivalent to quantum OAs, establishing a direct combinatorial connection between multipartite entanglement and structured quantum states.

It begins by tracing the concept of resilience from systems theory to social and political life, showing that resilience in democracy is not a mechanical property of systems but a dynamic, human-driven practice grounded in agency, resistance, and collective self-determination. The paper argues that with emerging challenges in the digital sphere, such as misinformation, surveillance capitalism, platform monopolies, deepfakes, and hybrid warfare, democracy can only endure if its digital dimensions are protected and transformed. Building on this foundation, the paper introduces a holistic approach to resilient digital democracy that spans environmental, technological, economic, political, and cultural domains, and advances strategies such as public-commons digital infrastructures, platform co-operatives, public service Internet platforms, free/libre open source software (FLOSS), participatory innovations, and hybrid offline/online democratic practices. The result is a fresh, interdisciplinary vision of how democracy can be reinvented in the digital age.","lang":"eng"}],"publication":"Open Research Europe","language":[{"iso":"eng"}],"year":"2025","quality_controlled":"1","title":"What is and how do we Achieve a Resilient Digital Democracy?","publisher":"F1000 Research Ltd","date_created":"2025-12-12T18:21:20Z","status":"public","type":"journal_article","article_type":"original","article_number":"387","project":[{"name":"INNOVAtive DEmocracy Through Digitalisation","_id":"1397"}],"_id":"63076","user_id":"21863","department":[{"_id":"136"},{"_id":"11"}],"citation":{"ieee":"C.

Multi-material design and the increasing trend towards producing large structural components using the megacasting process pose considerable challenges, particularly in the mechanical joining of aluminium-silicon (AlSi) castings. These castings typically exhibit low ductility and are prone to cracking when mechanically joined. Based on the excellent castability of hypoeutectic AlSi alloys, these are applied in sand casting and die casting as well as in megacasting. With a silicon content between 7 wt% and 12 wt%, these AlSi-alloys have a plate-like silicon phase that initiates cracks during mechanical joining. To enhance the joinability of castings, the research hypothesis is that improved solidification conditions enable a significant modification in the microstructure and therefore, increase the mechanical properties. During the manufacture of the castings using the sand casting process, the solidification conditions within the structural elements are varied to modify the microstructure to obtain castings with graded microstructure. The castings are evaluated using mechanical, microstructural and joining testing methods and finally, a microstructure-joinability correlation is established.","lang":"eng"}],"publication":"44th Conference of the International Deep Drawing Research Group (IDDRG 2025)","title":"Mechanical joinability of microstructurally graded structural components manufactured from hypoeutectic aluminium casting alloys","date_created":"2025-05-12T15:21:06Z","year":"2025","quality_controlled":"1"},{"citation":{"short":"M.C.

In the development of advanced lightweight automotive solutions, self-piercing riveting (SPR) offers the possibility of joining multi-material structures to fulfil a wide variety of requirements. With regard to the entire process chain, production-related pre-deformations of the parts to be joined can influence the geometric shape and load capacity of SPR joints. Various studies have investigated the influence of pre-stretched sheet materials, in the sense of pre-drawing processes, on the formation of SPR joints. The impact of pre-stretching sheet metals on the formation of their geometrical characteristics and the shear-tensile strength of SPR processes was observed [1]. Pre-rolled semi-finished products are also joined together in mixed material automotive structures, e.g. tailor rolled blanks. This work aims to investigate the influence of pre-rolled joining parts on the geometric formation and load-carrying capacity of SPR joints. For this purpose, sheets of metal are cold-formed using a rolling process to induce a defined strain-hardening state in the material and then joined in various combinations. As the degree of deformation increases, the rolling of samples can lead to minimal accumulation of damage in the sheet materials, which can influence the joint behaviour. The rolling process, as well as the subsequent joining process, are also investigated by FEM.

With regard to the entire process chain, production-related pre-deformations of the parts to be joined can influence the geometric shape and load capacity of SPR joints. Various studies have investigated the influence of pre-stretched sheet materials, in the sense of pre-drawing processes, on the formation of SPR joints. The impact of pre-stretching sheet metals on the formation of their geometrical characteristics and the shear-tensile strength of SPR processes was observed [1]. Pre-rolled semi-finished products are also joined together in mixed material automotive structures, e.g. tailor rolled blanks. This work aims to investigate the influence of pre-rolled joining parts on the geometric formation and load-carrying capacity of SPR joints. For this purpose, sheets of metal are cold-formed using a rolling process to induce a defined strain-hardening state in the material and then joined in various combinations. As the degree of deformation increases, the rolling of samples can lead to minimal accumulation of damage in the sheet materials, which can influence the joint behaviour. The rolling process, as well as the subsequent joining process, are also investigated by FEM. The influence of pre-rolled semi-finished products on the strength of the SPR joints is investigated.</jats:p>","lang":"eng"}],"user_id":"7850","department":[{"_id":"157"}],"project":[{"_id":"135","name":"TRR 285 - Subproject A01"},{"_id":"131","name":"TRR 285 - Project Area A"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"_id":"60977","language":[{"iso":"eng"}]},{"language":[{"iso":"eng"}],"_id":"60978","project":[{"name":"TRR 285 - Project Area A","_id":"131"},{"_id":"135","name":"TRR 285 - Subproject A01"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"department":[{"_id":"157"}],"user_id":"7850","abstract":[{"text":"The present study is an experimental analysis of the influence of pre-forming on the failure behaviour of clinched specimens under quasi-static and cyclic loading conditions.

As a widely used sheet metal in clinched joints within the automotive industry, the aluminum alloy EN AW-6014 has been the focus of numerous studies. High-cycle fatigue (HCF) is a critical aspect when assessing the durability of clinched joints. In the present work, the HCF behavior of EN AW-6014 T4 was explored both experimentally and numerically. To model the fatigue behavior, Lemaitre’s two-scale damage model was used. Two key parameters, damage strength and damage exponent, are necessary for numerical investigations of HCF behavior. These parameters were determined through experiments with flat specimens and subsequently validated within a numerical model of clinched joints.

Firstly, the reuse of products, individual parts and material reduces the need for new production or generation and the associated consumption of energy and resources. Secondly, it helps to avoid the generation of waste. Early consideration of circular economic principles in product development processes is essential to specifically promote reuse, reparability and recycling. Efficient recycling of assemblies requires well-defined strategies. However, various challenges hinder the efficiency of technical recycling processes in industrial applications. This paper presents an Ishikawa (fishbone) diagram-based approach to systematically identify and categorize these influences. The method is implemented within an industrial framework, highlighting key obstacles such as material composition, design constraints, use of technology, framework conditions, economic limitations and regulatory challenges. By applying a scenario analysis, this approach examines potential future developments and their impact on recycling-oriented design choices. This helps to identify critical influencing factors and supports the development of resilient and sustainable industrial practices. This framework will serve as the foundation for developing an automated approach to circular design, enabling industries to more effectively integrate sustainability into their processes and adapt to changing environmental demands."}],"file":[{"content_type":"application/pdf","relation":"main_file","success":1,"creator":"kathiroh","date_created":"2026-02-24T13:33:47Z","date_updated":"2026-02-24T13:33:47Z","access_level":"closed","file_name":"GCSM_2025_Rohde_updated.pdf","file_id":"64617","file_size":333257}]},{"publication_status":"published","quality_controlled":"1","publication_identifier":{"issn":["2474-395X"]},"citation":{"short":"P.K.

V-SPR enables adaptation to changing boundary conditions, such as a change in the material thickness combination, without varying the rivet die combination due to increased punch actuation and the use of multi-range capable rivets [1]. The inner punch first sets the rivet. The outer punch then forms the rivet head to the respective sheet thickness. For this, the rivet requires a hard shank and a ductile rivet head, which is achieved by an inductive local hardening process [2]. Until now, the joint formation of rivets with graded hardness profile has been challenging to estimate in the FEM simulation due to the inhomogeneous material conditions in the rivet. In this study, a method capable of reproducing the experimentally determined hardness levels of rivets in detail is shown. This FE model enables the realistic modelling of the mechanical properties of the rivet on the basis of the hardness profile in order to predict the correct deformation processes and stresses during the riveting process. First, the detailed experimental hardness mapping of the locally heat-treated rivets is transferred into the FE model. The FEM material model can predict the local strength of the rivet based on hardness by scaling the flow curves. To estimate the predictive capability of the FEM model, the joint formation of rivets with different graded hardness profiles is compared experimentally and simulative. Based on the validated model, the influence of different rivet hardness profiles on the joint formation is analysed numerically. By adapting the material model, a high level of correlation between the experiment's joint formation and the simulation can be achieved."}],"user_id":"7850","department":[{"_id":"43"},{"_id":"157"}],"project":[{"_id":"130","name":"TRR 285: TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"_id":"146","name":"TRR 285 – C02: TRR 285 - Subproject C02"},{"_id":"131","name":"TRR 285 - A: TRR 285 - Project Area A"},{"_id":"135","name":"TRR 285 – A01: TRR 285 - Subproject A01"}],"_id":"60440","language":[{"iso":"eng"}]},{"user_id":"114764","project":[{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"},{"_id":"148","name":"TRR 285 - Subproject C04"}],"_id":"64562","file_date_updated":"2026-02-20T14:14:36Z","type":"conference","status":"public","editor":[{"first_name":"Martina","last_name":"Zimmermann","full_name":"Zimmermann, Martina"}],"author":[{"id":"114764","full_name":"Dargel, Alrik","last_name":"Dargel","first_name":"Alrik"},{"last_name":"Köhler","full_name":"Köhler, Daniel","id":"83408","first_name":"Daniel"},{"first_name":"Maik","full_name":"Gude, Maik","last_name":"Gude"},{"full_name":"Kupfer, Robert","last_name":"Kupfer","first_name":"Robert"}],"volume":43,"date_updated":"2026-02-24T15:12:59Z","conference":{"end_date":"2025-11-28","location":"Dresden","name":"43.
