description: Neutrinos are the most elusive particles known. Heavier sterile neutrinos mixing with the standard neutrinos might solve the mystery of the baryon asymmetry of the universe. In this letter, we show that among all future energy frontier accelerators, muon colliders will provide the farthest search reach for such neutrinos for mass ranges above the $Z$ pole into the multi-TeV regime. We compare the performance of muon with electron colliders of the same machine energy and briefly discuss the complementarity in flavor space between the two types of accelerators.

Das anwachsende Bewusstsein von Bürgern für Umwelt erfordert zunehmende fachliche Kenntnisse zur Interpretation bereitgestellter Umweltinformationen. Umweltinformationen zum Feinstaub in der Heimatstadt der Bürger werden als PM2,5 oder PM10 zur Verfügung gestellt, wobei eine Interpretation dieser Werte ohne Fachkenntnisse über die Kennzahlen und damit verbundener Grenzwerte viele Fragen beim Bürger offen lässt. An dieser Stelle will das Projekt PUUK unterstützen, indem zunächst der Informationsbedarf der Bürger mittels einer Onlinestudie ermittelt wird und anschließend ein bedarfsgerechtes Umweltinformationsportal entwickelt wird.

description: We show that superconductivity can arise in semiconductors with a band in the shape of a Mexican hat when the chemical potential is tuned close to the band edge, but not intersecting the band, as long as interactions are sufficiently strong. Hence, this is an example where superconductivity can emerge from a band insulator when interactions exceed a threshold. Semiconductors with simple cubic symmetry point groups and with strong spin-orbit coupling provide an example of a system with such band dispersion.

description: In this paper we give the first example of a surface bundle over a surface with at least three fiberings. In fact, for each $n \ge 3$ we construct $4$-manifolds $E$ admitting at least $n$ distinct fiberings $p_i: E \to Σ_{g_i}$ as a surface bundle over a surface with base and fiber both closed surfaces of negative Euler characteristic. We give examples of surface bundles admitting multiple fiberings for which the monodromy representation has image in the Torelli group, showing the necessity of all of the assumptions made in the main theorem of our recent paper [arXiv:1404.0066]. Our examples show that the number of surface bundle structures that can be realized on a $4$-manifold $E$ with Euler characteristic $d$ grows exponentially with $d$.

description: A data-driven quality assessment of bicycle infrastructure is necessary in times of crisis to support the decision-making process in cycling promotion. The INFRASense project was initiated to support the scoring of bike paths by providing new crowdsourcing data that is combined with other relevant data sources (traffic amount, accidents, citizen reportings etc.). The storage and processing of heterogeneous bike infrastructure data may be a challenge. With its flexibility a Data Lake could be an alternative to the traditional Data Warehouse. In the first step the paper gives an overview about data-driven initiatives in the use-case of bike infrastructure quality assessment and the recently started research project INFRASense. We will provide an overview about data sources that may potentially be included into the data driven quality assessment. Big Bicycle Data is available in many different structures and formats (CSV, XML, SHP etc.). In the second step the concepts of Data Lake and Data Warehouse are introduced. The benefits and weaknesses of these two solutions are shown followed by a discussion about which one of these is the best concept for storage, processing, and analysis of heterogeneous bicycle infrastructure data. In the last step we are providing an outlook how an efficient bicycle infrastructure data management system could be implemented.

description: We study the ground state and the low-lying excitations of a trapped Bose gas in an isotropic harmonic potential for very small ($\sim 3$) to very large ($\sim 10^7$) particle numbers. We use the correlated two-body basis functions and the shape-dependent van der Waals interaction in our many-body calculations. We present an exhaustive study of the effect of inter-atomic correlations and the accuracy of the mean-field equations considering a wide range of particle numbers. We calculate the ground state energy and the one-body density for different values of the van der Waals parameter $C_{6}$. We compare our results with those of the modified Gross-Pitaevskii results, the correlated Hartree hypernetted-chain equations (which also utilize the two-body correlated basis functions), as well as of the Diffusion Monte Carlo for hard sphere interactions. We observe the effect of the attractive tail of the van der Waals potential in the calculations of the one-body density over the truly repulsive zero-range potential as used in the Gross-Pitaevskii equation and discuss the finite-size effects. We also present the low-lying collective excitations which are well described by a hydrodynamic model in the large particle limit.

Subjects: subject: forensic science||computer vision||AI frameworks

description: Shows like CSI seem to convey a certain view on the capabilities of forensic science based on the vast progress of digitalisation and the new technology, that goes along with it. But those depictions can be misleading and hardly represent a realistic reflection of reality. Nevertheless, this representation influences the public view on digital forensic analysis. This phenomenon is also known as the CSI effect. To present a more realistic view on practices in digital forensics, we want to introduce typical image and video analysis methods used in tackling real life forensic challenges and point to their capabilities as well as their limits. In this context an important area is image and video enhancement. With methods such as Super Resolution, images can be scaled up, their corresponding resolution gets enhanced and image noise can be reduced. During the subsequent image analysis, methods ranging from purely cognitive analysis to extraction of raw pixel values and various semantic information from the image or video, utilizing AI frameworks, are used. This allows for example to detect and analyse faces up to whole people, as well as objects in images or videos.

Subjects: subject: Smartness||learning systems||Economics of Convention||competences

description: Smart systems are not just technical tools but endowed with agency and discretion. Whereas their character as a black box is widely discussed, their moral inaccessibility is not. Broadening the issue of ‘smartness’, our research concern is as follows: How is the complex, typically ambiguous and contradictory moral infrastructure of late modern societies mirrored and eventually transformed by smart and learning systems? In order to conceptualize this question, we combine the normative reasoning of the Economics of Convention (EC), which distinguishes several competing moral orders, with the assumed smartness of learning systems. We propose to confront smartness with conflicting moral registers and to revise the competences which enable learning systems and humans to interact in a common “space of negotiation.”

Subjects: subject: Multiagent System||OPC UA||Organizational Model||Cyber-physical System

description: Developing adaptive Cyber-physical Systems (CPS) requires integrating physical components with run-time controls which monitor and adjust the operation of components appropriately. The use of multiagent systems (MAS) is an established approach for embedding adaptive features and the integration of multiagent systems in industrial systems is an active field of research. Industry standards, like OPC UA, allow for vendor independent information exchange and unit control in industrial settings. Here, we propose to represent MAS organizations within OPC UA information models. The organization of a MAS can be seen as a crosscutting concern in structing and integration distributed adaptive applications. Explicit modelling allows to express organizational structures in industrial settings and enables monitoring of these structures at run- time with established tools and frameworks for industrial control.
Equivariant KK-theory and the continuous Rokhlin property

description: We introduce and study the continuous Rokhlin property for actions of compact groups on C*-algebras. An important technical result is a characterization of the continuous Rokhlin property in terms of asymptotic retracts. As a consequence, we derive strong KK-theoretical obstructions to the continuous Rokhlin property. Using these, we show that the UCT is preserved under formation of crossed products and passage to fixed point algebras by such actions, even in the absence of nuclearity. Our analysis of the KK-theory of the crossed product allows us to prove a $\mathbb{T}$-equivariant version of Kirchberg-Phillips: two circle actions with the continuous Rokhlin property on Kirchberg algebras are conjugate whenever they are KK$^{\mathbb{T}}$-equivalent. In the presence of the UCT, this is equivalent to having isomorphic equivariant K-theory. We moreover characterize the KK$^{\mathbb{T}}$-theoretical invariants that arise in this way. Finally, we identify a KK$^{\mathbb{T}}$-theoretic obstruction to the continuous property, which is shown to be the only obstruction in the setting of Kirchberg algebras. We show by means of explicit examples that the Rokhlin property is strictly weaker than the continuous Rokhlin property.

description: We prove that crossing probabilities for the critical planar Ising model with free boundary conditions are conformally invariant in the scaling limit, a phenomenon first investigated numerically by Langlands, Lewis and Saint-Aubin. We do so by establishing the convergence of certain exploration processes towards SLE$(3,\frac{-3}2,\frac{-3}2)$. We also construct an exploration tree for free boundary conditions, analogous to the one introduced by Sheffield.

This general functional analytic framework provides a universal language for various combinatorial limit notions. In particular it makes it possible to assign limit objects to multigraph sequences that are convergent in the sense of node-and-edge homomorphism numbers, and it generalizes the limit theory for graph sequences with compact decorations.

description: Textual social media content and short messages have gained in importance as evidence in criminal investigations. Yet, the large number of textual data poses a great challenge for investigators. Even though text retrieval systems can assist in finding evidential messages, the success of the search still depends on entering appropriate search terms. However, for colloquial texts these are difficult to determine because one cannot be sure about what terms are used in the texts and might be of interest. Therefore, the aim is to develop a method that recommends keywords and searches phrases based on the underlying data. A particular challenge here is that the appropriate search terms are often non-obvious words that are not expected to be found in the data, but are particularly relevant. In total, four methods were evaluated for extracting and suggesting the most relevant terms and phrases using a real-life dataset. The best results were obtained with topic modeling considering syntagmatic relations.

description: The horizontal clauses of arts 8-13 TFEU address a persistent challenge for the European Union: combining distinct policy objectives across the many areas of Union activity. Whilst they cannot be used as a legal basis for the adoption of EU measures, they legitimize the pursuit of the objectives they set forth, through legal bases that are designed to pursue some other treaty objective. This Article explores case law of the Court of Justice of the European Union (CJEU) on the legal nature of arts 8-13 TFEU, as well as their functions and input to judicial review. The analysis examines whether the horizontal clauses, as construed by the CJEU, create a legal obligation for mainstreaming. It also probes their relationship with the exercise of Union competences in the broader areas that they ad-dress (save for art. 13 TFEU due to the lack of an EU competence for animal welfare) and their implications for the choice of the legal basis of a mainstreaming measure. This Article further sheds light on the CJEU's treatment of the horizontal clauses in cases concerning restrictions of fundamental rights and free movement, it discusses their contribution to the interpretation of EU secondary legislation and examines whether the horizontal clauses may serve to invalidate an EU measure. The analysis overall attests to moderate judicial use of arts 8-13 TFEU but shows that relevant provisions en-rich and corroborate the CJEU's reasoning on different accounts.

description: Within the framework of higher-twist collinear factorization, transverse momentum broadening for the final hadrons in semi-inclusive deeply inelastic $e+A$ collisions is studied at the next-to-leading order (NLO) in perturbative QCD. Through explicit calculations of real and virtual corrections at twist-4, the transverse-momentum-weighted differential cross section due to double scattering is shown to factorize at NLO and can be expressed as a convolution of twist-4 nuclear parton correlation functions, the usual twist-2 fragmentation functions and hard parts which are finite and free of any divergences. A QCD evolution equation is also derived for the renormalized twist-4 quark-gluon correlation function which can be applied to future phenomenological studies of transverse momentum broadening and jet quenching at NLO.

Subjects: subject: Wi-Fi||MAC-Address||Cellular||IMSI||Evidence||Law Enforcement

description: Mobile devices such as smartphones constantly probe the surrounding wireless medium for providing services to users, thus leaving traces that, when analysed, can link their presence to a crime. Those passive observations, combined with actively tricking devices to cooperate with foreign networks, can yield an attractive device profile. Though past research explores independent methods for collecting single identifiers of devices, a holistic approach for data seizure and utilization for law enforcement is missing. As devices carried by criminals are not willing to share identifiers with a victim's home network, we combine collection processes for device-identifying data with exploiting viable wireless communication protocols. Using the presented approach allows to build a system supporting law enforcement with evidence that certain mobile devices were present at a crime scene and thus may give clues on further investigations on suspects.

description: Deep technology (DT) startups develop physical products based on cutting-edge technologies to create entirely new markets. Consequently, they have a comparably high demand for specialized infrastructure, expert knowledge and extended development cycles which result in large capital expenditures. However, especially early-stage (pre-seed/seed) DT startups often fail to raise sufficient funding from investors due to their large capital needs, severe technical challenges often not fully understood by investors, and long time to market. Therefore, this paper analyses the underlying issues by developing a model to support early-stage DT startups by assessing their fit with different investor types (e.g., business angels, venture capital, or other investment opportunities) in order to streamline and focus their funding process. This is achieved by applying the principal-agent-framework to model the information asymmetry between different investor types and DT startups. Relevant signals between startups and investors are derived from literature, adapted to the requirements set by the signaling theory, as an approach to counteract the information asymmetry, and included into the model.

description: In der Wasserwirtschaft werden vermehrt die Potenziale von Digital Twin und Predictive Maintenance diskutiert. Es fehlt jedoch an Prototypen, welche die theoretischen Überlegungen mit den Bedarfen der Praxis abgleichen. Um diese Lücke zu schließen, wurden am Beispiel des Wasserwerks der Nordseeinsel Langeoog die Konzepte Digital Twin und Predictive Maintenance erprobt. Das Ziel war es, einen horizontalen Prototypen zu entwickeln, der vom Sensor bis zum Dashboard alle Informationsebenen abbildet, um Rückschlüsse auf Potenziale zur Digitalisierung und Einschränkungen in den Technologien zu ermitteln. Durch den Prototypen konnte gezeigt werden, dass durch den Einsatz von Digital Twins und Predictive Maintenance Methoden ein besseres Verständnis über den aktuellen Systemzustands für das Wartungspersonal erlangt werden kann.

description: Existing widely-used pileup removal approaches correct the momenta of individual jets. In this article we introduce an event-level, particle-based pileup correction procedure, SoftKiller. It removes the softest particles in an event, up to a transverse momentum threshold that is determined dynamically on an event-by-event basis. In simulations, this simple procedure appears to be reasonably robust and brings superior jet resolution performance compared to existing jet-based approaches. It is also nearly two orders of magnitude faster than methods based on jet areas.

description: Data represent a key resource for firm success, being used for strategic decision making and increasing business process efficiency. Despite the large potential of data sharing within data ecosystems or markets, firms are reluctant to do this, due to fear of losing competitive edges, lack of trust and ambiguity regarding data value. According to prior research, data value vastly depends on usage and quality. This paper focuses on data quality, as the lack of methods for quantifying data quality is one main reason for missing comprehensible data valuation approaches. We analyze 15 existing data quality indices (DQI) from theory and practice, identify relevant data quality dimensions and discuss metrics for applicability in data valuation approaches for data ecosystems and markets. Based on a quantitative study, we propose a DQI concept for developing transparent, objective data valuation methods, while providing a better understanding of inter- and intra-organizational data value.

description: The ability of a plasma surrounding spinning black holes to extract rotational energy and power energetic emissions has been recognized as a key astrophysical phenomenon. Important insights into the nature of this process are obtained through the analysis of the interplay between a force-free magnetosphere and the black hole. This task involves solving a complicated system of equations, often requiring complex numerical simulations. Recent analytical attempts at tackling this problem have exploited the fact that the near horizon region of extreme Kerr (NHEK) is endowed with an enhanced symmetry group. We continue in this direction and show that for some conformally self-similar solutions, the NHEK force-free equations reduce to a single non-linear ordinary differential equation which is difficult to solve with straightforward integration. We here introduce a new approach specifically tailored to this problem and describe how one can obtain physically meaningful solutions.

description: Im Rahmen ihrer (universitären) Ausbildung müssen Informatikerinnen und Informatiker unumstritten auch für ethische Aspekte im Zusammenhang mit der Entwicklung, Gestaltung, Nutzung und Wirkung von Informatiksystemen sensibilisiert werden. Im Informatikstudium finden ethische Fragestellungen üblicherweise Einzug in die Lehrinhalte von Veranstaltungen, die versuchen, den Inhaltsbereich Informatik und Gesellschaft möglichst multidimensional (gesellschaftlich, ökonomisch, rechtlich, politisch, ethisch, ...) abzudecken. Der Beitrag geht der Frage nach, inwiefern die Teilnahme an einer entsprechenden Lehrveranstaltung eine Auswirkung auf die ethische Position der Studierenden hat. Die Ergebnisse deuten darauf hin, dass die Teilnahme an der untersuchten Veranstaltung die ethische Position kaum beeinflusst, was mit Blick auf die Adäquatheit der Adressierung ethischer Kompetenzen in entsprechend vielschichtigen Veranstaltungen diskutiert wird.

description: We report the results of new differential force measurements between a test mass and rotating source masses of gold and silicon to search for forces beyond Newtonian gravity at short separations. The technique employed subtracts the otherwise dominant Casimir force at the outset and, when combined with a lock-in amplification technique, leads to a significant improvement (up to a factor $10^{3}$) over existing limits on the strength (relative to gravity) of a putative force in the 40--8000 nm interaction range.

description: Die Relevanz alternativer Antriebe steigt. Auch für Unternehmen wird eine Abkehr von konventionellen Antrieben zunehmend interessant. Die bekannteste Alternative zu konventionellen Fahrzeugen stellt Elektromobilität dar. Die Möglichkeit, Elektromobilität in verschiedenen Unternehmen einzusetzen wurde folglich auch in der Forschung vielfach betrachtet. In diesem Paper wird daher mit Hilfe einer Literaturanalyse untersucht, wo die Forschungsschwerpunkte bei dem Einsatz von Elektromobilität liegen. Es kann gezeigt werden, dass fünf Themenschwerpunkte existieren. Dies sind zum einen Entscheidungsunterstützung und die Auswirkungen einer Elektrifizierung. Zum anderen werden die Akzeptanz von Elektromobilität, das Laden sowie das Potential, das Elektromobilität bietet, schwerpunktmäßig untersucht.

description: Video and image material is becoming increasingly ubiquitous thus its potential as evidence in forensic investigations is growing. Once faces are hidden however, the value of surveillance footage is restricted unless there is another biometric trait that can be observed by camera such as linear body measurements. There is much biological evidence for human body proportions exhibiting much individual variation. Nevertheless, the probability of there being two individuals that match in their respective proportions ultimately determines its usability for the assignment, exclusion and even identification of persons in the forensic domain. This work is concerned with approaches for duplicate probability estimations derived from anthropometric measures. Here, we present a novel frequentist estimation using a dataset of 340 individuals and their respective anthropometric measurements. Drawing on density kernel estimations of measurement dissimilarity, we propose the duplicate probability to be in the order of 10^−15 to 10^−8.

description: We exploit the standard techniques of the supervariable approach to derive the nilpotent Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations for a toy model of the Hodge theory (i.e. a rigid rotor) and provide the geometrical meaning and interpretation to them. Furthermore, we also derive the nilpotent (anti-)co-BRST symmetry transformations for this theory within the framework of the above supervariable approach. We capture the (anti-)BRST and (anti-)co-BRST invariance of the Lagrangian of our present theory within the framework of augmented supervariable formalism. We also express the (anti-)BRST and (anti-)co-BRST charges in terms of the supervariables (obtained after the application of the (dual-)horizontality conditions and (anti-)BRST and (anti-)co-BRST invariant restrictions) to provide the geometrical interpretations for their nilpotency and anticommutativity properties. The application of the dual-horizontality condition and ensuing proper (i.e. nilpotent and absolutely anticommuting) fermionic (anti-)co-BRST symmetries are completely novel results in our present investigation.

description: There is a growing consensus in research and practice that value-creating networks and ecosystems are supplementing the traditional distinction between the internal firm and market perspectives. To achieve joint value in ecosystems, it is crucial to align the various interests of independently acting ecosystem actors and create a common vision. In this paper, we argue that the ecosystem-wide use of product roadmaps may help with this. To get a better understanding of how roadmapping is conducted in the dynamic ecosystem environment, we systematize the main characteristics of product roadmaps and perform a conceptual comparison with the known challenges of ecosystem management. Comparing the two concepts of ecosystems and product roadmaps, we highlight the fit between the characteristics and objectives of the roadmaps and the challenges of ecosystem management. Hence, we propose to experiment with the ecosystem-wide use of product roadmaps as well as the empirical study of the challenges emerging in the process and the associated redesign of the roadmaps.

description: Die zunehmende Vernetzung und Digitalisierung bringen große Veränderungen aber auch Vulnerabilitäten auf allen Ebenen mit sich. Um eine Infrastruktur für ein resilientes Smart Farming (RSF) zu erstellen, welche die Fortschritte der Digitalisierung in der Landwirtschaft nutzt, ohne die Ausfallsicherheit der landwirtschaftlichen Primärproduktion und damit die Lebensmittelversorgung der Verbraucher zu gefährden, bedarf speziell der Sicherheitsaspekt einer kritischen Auseinandersetzung. Der Workshop adressiert diese Forschungsherausforderungen durch Beiträge zu einem umfassenden Monitoring für den Transport von künstlichen Besamungsdosen, zu modularer, sicherer und robuster Steuerungsarchitektur für autonomes Bewirtschaften von Weinbergen, zur Resilienz im ländlichen Raum, zum Aufbau eines informellen Netzwerkes zur Förderung der Digitalisierung in der Landwirtschaft und zu Effizienz und Nachhaltigkeit durch Green-IT.
