AB - Federkraftbremsen für industrielle Anwendungen tragen häufig zur Erfüllung einer Sicherheitsfunktion bei. Um Sicherheitsfunktionen zu validieren, sind Sicherheitskennzahlen einzelner Elemente erforderlich. Für Federkraftbremsen werden diese bis dato nur vereinzelt zur Verfügung gestellt. Weiterhin existiert kein Konsens über deren Ermittlung.
In dieser Arbeit wird ein bauteilorientierter Ansatz zur Ermittlung von Sicherheitskennzahlen für Federkraftbremsen diskutiert. Unter Berücksichtigung relevanter rechtlich-normativer Rahmenbedingungen wird eine qualitative Zuverlässigkeitsanalyse durchgeführt. Es folgt die simulative und experimentelle Untersuchung einer konkreten Bauteilschadensart. Abschließend wird ein Zuverlässigkeitsblockdiagramm auf Grundlage gewonnener Erkenntnisse hergeleitet.

AB - Elektromechanische Spindelhubantriebe werden in einer Vielzahl von unterschiedlichen Anwendungen mit jeweils spezifischen Prozesskennwerten eingesetzt. Dabei kann es vorkommen, dass das dynamische Betriebsverhalten eines Spindelhubantriebs unerwünschte Schwingungen aufweist. Um unerwünschte Betriebszustände bereits vor dem realen Anwendungsfall ersichtlich zu machen, wird im Rahmen dieser Arbeit ein Simulationsmodell von Spindelhubantrieben mit Trapezgewindespindel entwickelt. Dazu wird zunächst recherchiert, welche Schwingungsphänomene in einem Spindelhubantrieb entstehen können. Die Modellbildung wird durch eine Verifikation anhand der identifizierten Schwingphänomene begleitet. Im Anschluss erfolgt eine Validierung des Simulationsmodells durch experimentelle Messungen. Mittels einer Parameterstudie werden Einflussgrößen von zwei Schwingphänomenen analysiert. Die erzielten Erkenntnisse werden anschließend erfolgreich auf ein zuvor schwingungsanfälliges Antriebssystem zugunsten eines stabilen, dynamischen Betriebsverhaltens übertragen, wodurch die Gültigkeit des Modells nachgewiesen wird.

AB - The aggregation of human islet amyloid polypeptide (hIAPP) plays a major role in the pathogenesis of type 2 diabetes mellitus (T2DM), and numerous strategies for controlling hIAPP aggregation have been investigated so far. In particular, several organic and inorganic nanoparticles (NPs) have shown the potential to influence the aggregation of hIAPP and other amyloidogenic proteins and peptides. In addition to conventional NPs, DNA nanostructures are receiving more and more attention from the biomedical field. Therefore, in this work, we investigated the effects of two different DNA origami nanostructures on hIAPP aggregation. To this end, we employed in situ turbidity measurements and ex situ atomic force microscopy (AFM). The turbidity measurements revealed a retarding effect of the DNA nanostructures on hIAPP aggregation, while the AFM results showed the co-aggregation of hIAPP with the DNA origami nanostructures into hybrid peptide–DNA aggregates. We assume that this was caused by strong electrostatic interactions between the negatively charged DNA origami nanostructures and the positively charged peptide. Most intriguingly, the influence of the DNA origami nanostructures on hIAPP aggregation differed from that of genomic double-stranded DNA (dsDNA) and appeared to depend on DNA origami superstructure. DNA origami nanostructures may thus represent a novel route for modulating amyloid aggregation in vivo.

AB - Immobile Holliday junctions represent not only the most fundamental building block of structural DNA nanotechnology but are also of tremendous importance for the in vitro investigation of genetic recombination and epigenetics. Here, we present a detailed study on the room-temperature assembly of immobile Holliday junctions with the help of the single-strand annealing protein Redβ. Individual DNA single strands are initially coated with protein monomers and subsequently hybridized to form a rigid blunt-ended four-arm junction. We investigate the efficiency of this approach for different DNA/protein ratios, as well as for different DNA sequence lengths. Furthermore, we also evaluate the potential of Redβ to anneal sticky-end modified Holliday junctions into hierarchical assemblies. We demonstrate the Redβ-mediated annealing of Holliday junction dimers, multimers, and extended networks several microns in size. While these hybrid DNA–protein nanostructures may find applications in the crystallization of DNA–protein complexes, our work shows the great potential of Redβ to aid in the synthesis of functional DNA nanostructures under mild reaction conditions.

AB - Abstract
The surface-assisted hierarchical self-assembly of DNA origami lattices represents a versatile and straightforward method for the organization of functional nanoscale objects such as proteins and nanoparticles. Here, we demonstrate that controlling the binding and exchange of different monovalent and divalent cation species at the DNA-mica interface enables the self-assembly of highly ordered DNA origami lattices on mica surfaces. The development of lattice quality and order is quantified by a detailed topological analysis of high-speed atomic force microscopy (HS-AFM) images. We find that lattice formation and quality strongly depend on the monovalent cation species. Na+ is more effective than Li+ and K+ in facilitating the assembly of high-quality DNA origami lattices, because it is replacing the divalent cations at their binding sites in the DNA backbone more efficiently. With regard to divalent cations, Ca2+ can be displaced more easily from the backbone phosphates than Mg2+ and is thus superior in guiding lattice assembly. By independently adjusting incubation time, DNA origami concentration, and cation species, we thus obtain a highly ordered DNA origami lattice with an unprecedented normalized correlation length of 8.2. Beyond the correlation length, we use computer vision algorithms to compute the time course of different topological observables that, overall, demonstrate that replacing MgCl2 by CaCl2 enables the synthesis of DNA origami lattices with drastically increased lattice order.

AB - Das grundlegende Verständnis von makroskopischen Haftungsphänomenen beginnt bei der Analyse von molekularen Wechselwirkungen unter kontrollierten Bedingungen (Materialeigenschaften, chemische Oberflächenzusammensetzung, und weiteren Einflussfaktoren wie z.B. pH-Wert, Elektrolytzusammensetzung). In dieser Arbeit wurden die molekularen und makroskopischen Haftungseigenschaften von makromolekularer Poly(acrylsäure) (PAA) als potenzieller Haftungsvermittler auf Edelstahl und verschiedenen nanostrukturierten Zinkoxid (ZnO) Oberflächen untersucht, die mittels elektrochemischer und hydrothermalen Abscheidemethoden auf Edelstahl und feuerverzinktem Stahl (HDG) abgeschieden wurden. Molekulare Haftungsmechanismen zwischen PAA und ZnO basierend auf multi-koordinativen Bindungen in Abhängigkeit von der Oberflächenchemie und der Verweilzeit konnten mit der s.g. Einzelmolekülspektroskopie aufgeklärt werden. Die Ergebnisse aus weiteren makroskopischen Enthaftungsexperimenten und Rückseitenanalytik bei der Verwendung von verdünnten, wässrigen PAA-Lösungen zur Vorbehandlung von nanostrukturierten ZnO Filmen auf HDG Stahl untermauerten die starken Wechselwirkungen zwischen ZnO-PAA. Mittels Elektropolymerisation abgeschiedene PAA Filme zeigten eine signifikante Steigerung in den makroskopischen Haftungseigenschaften bei einem ausgewählten Model-Epoxid-Amin-Klebstoff auf Edelstahl. Die Kombination von ZnO Tetrapoden (ZnO TP) und PAA als hybridische, haftungsverbessernde Sprühbeschichtungen aus wässrigen Dispersionen auf Poly(propylen) Folien bestätigten, sowohl die chemischen, als auch mechanischen Haftungseigenschaften von nanostrukturierten ZnO/PAA Interphasen. Daher können PAA/Metalloxid-Grenzflächen die Tür in diversen technischen Ansätzen für innovative Anwendungen öffnen, wie z.B. in Sprühapplikationstechniken.

AB - Many dimensionality and model reduction techniques rely on estimating dominant eigenfunctions of associated dynamical operators from data. Important examples include the Koopman operator and its generator, but also the Schrödinger operator. We propose a kernel-based method for the approximation of differential operators in reproducing kernel Hilbert spaces and show how eigenfunctions can be estimated by solving auxiliary matrix eigenvalue problems. The resulting algorithms are applied to molecular dynamics and quantum chemistry examples. Furthermore, we exploit that, under certain conditions, the Schrödinger operator can be transformed into a Kolmogorov backward operator corresponding to a drift-diffusion process and vice versa. This allows us to apply methods developed for the analysis of high-dimensional stochastic differential equations to quantum mechanical systems.

AB - Simulationsmethoden bieten die Möglichkeit, instabile Betriebszustände von Antriebssystemen noch vor dem Einsatz in einer realen Anwendung zu identifizieren und gezielt Gegenmaßnahmen abzuleiten. In dem vorliegenden Artikel wird die Entwicklung eines Simulationsmodells für elektro- mechanische Spindelhubantriebe beschrieben. Im Fokus der Betrachtung stehen insbesondere reibungsinduzierte Schwingphänomene, die in Schneckengetrieben und Trapezgewindespindeln entstehen können. Das Simulationsmodell wird anhand von experimentellen Messungen für mehrere stabile Betriebspunkte und für einen instabilen Betriebszustand validiert. Eine Diskussion der Ergebnisse schließt den Beitrag ab.

AB - After the introduction of CbCR – pursuant to the BEPS Project (Action 13) in 2015 –, which was established to reduce the information asymmetry between MNEs and tax authorities of the countries they operate in, now public CbCR – as suggested by the EU Commission in 2016 – is discussed as a next step. Here, the objective is to overcome information asymmetries between MNEs and the general public of the countries they operate in. Starting from the assumption that regulators care about the legitimacy of tax laws, this article evaluates pros and cons of public CbCR. The authors find that from the perspective of information asymmetries, public CbCR increases tax transparency only marginally at best. Accordingly, it is concluded that democracies that are based on the rule of law seem to rely on pillories in terms of public CbCR to enforce fair tax payments.

AB - The maintenance of efficient and robust overlay networks is one
of the most fundamental and reoccurring themes in networking.
This paper presents a survey of state-of-the-art
algorithms to design and repair overlay networks in a distributed
manner. In particular, we discuss basic algorithmic primitives
to preserve connectivity, review algorithms for the fundamental
problem of graph linearization, and then survey self-stabilizing
algorithms for metric and scalable topologies.
We also identify open problems and avenues for future research.

AB - We consider the clock synchronization problem in the (discrete) beeping model: Given a network of $n$ nodes with each node having a clock value $\delta(v) \in \{0,\ldots T-1\}$, the goal is to synchronize the clock values of all nodes such that they have the same value in any round.
As is standard in clock synchronization, we assume \emph{arbitrary activations} for all nodes, i.e., the nodes start their protocol at an arbitrary round (not limited to $\{0,\ldots,T-1\}$).
We give an asymptotically optimal algorithm that runs in $4D + \Bigl\lfloor \frac{D}{\lfloor T/4 \rfloor} \Bigr \rfloor \cdot (T \mod 4) = O(D)$ rounds, where $D$ is the diameter of the network.
Once all nodes are in sync, they beep at the same round every $T$ rounds.
The algorithm drastically improves on the $O(T D)$-bound of \cite{firefly_sync} (where $T$ is required to be at least $4n$, so the bound is no better than $O(nD)$).
Our algorithm is very simple as nodes only have to maintain $3$ bits in addition to the $\lceil \log T \rceil$ bits needed to maintain the clock.
Furthermore we investigate the complexity of \emph{self-stabilizing} solutions for the clock synchronization problem: We first show lower bounds of $\Omega(\max\{T,n\})$ rounds on the runtime and $\Omega(\log(\max\{T,n\}))$ bits of memory required for any such protocol.
Afterwards we present a protocol that runs in $O(\max\{T,n\})$ rounds using at most $O(\log(\max\{T,n\}))$ bits at each node, which is asymptotically optimal with regards to both, runtime and memory requirements.

AB - The continuous innovation of its business models is an important task for a company to stay competitive. During this process, the company has to validate various hypotheses about its business models by adapting to uncertain and changing customer needs effectively and efficiently. This adaptation, in turn, can be supported by the concept of Software Product Lines (SPLs). SPLs reduce the time to market by deriving products for customers with changing requirements using a common set of features, structured as a feature model. Analogously, we support the process of business model adaptation by applying the engineering process of SPLs to the structure of the Business Model Canvas (BMC). We call this concept a Business Model Decision Line (BMDL). The BMDL matches business domain knowledge in the form of a feature model with customer needs to derive hypotheses about the business model together with experiments for validation. Our approach is effective by providing a comprehensive overview of possible business model adaptations and efficient by reusing experiments for different hypotheses. We implement our approach in a tool and illustrate the usefulness with an example of developing business models for a mobile application.

AB - To build successful products, the developers have to adapt their product features and business models to uncertain customer needs. This adaptation is part of the research discipline of Hypotheses Engineering (HE) where customer needs can be seen as hypotheses that need to be tested iteratively by conducting experiments together with the customer. So far, modeling support and associated traceability of this iterative process are missing. Both, in turn, are important to document the adaptation to the customer needs and identify experiments that provide most evidence to the customer needs. To target this issue, we introduce a model-based HE approach with a twofold contribution: First, we develop a modeling language that models hypotheses and experiments as interrelated hierarchies together with a mapping between them. While the hypotheses are labeled with a score level of their current evidence, the experiments are labeled with a score level of maximum evidence that can be achieved during conduction. Second, we provide an iterative process to determine experiments that offer the most evidence improvement to the modeled hypotheses. We illustrate the usefulness of the approach with an example of testing the business model of a mobile application.

AB - AbstractThe C-type lectin receptor langerin plays a vital role in the mammalian defense against invading pathogens. Its function hinges on the affinity to its co-factor Ca2+ which in turn is regulated by the pH. We studied the structural consequences of pro-tonating the allosteric pH-sensor histidine H294 by molecular dynamics simulations (total simulation time: about 120 μs) and Markov models. We discovered a mechanism in which the signal that the pH has dropped is transferred to the Ca2+-binding site without transferring the initial proton. Instead, protonation of H294 unlocks a conformation in which a protonated lysine side-chain forms a hydrogen bond with a Ca2+-coordinating aspartic acid. This destabilizes Ca2+ in the binding pocket, which we probed by steered molecular dynamics. After Ca2+-release, the proton is likely transferred to the aspartic acid and stabilized by a dyad with a nearby glutamic acid, triggering a conformational transition and thus preventing Ca2+-rebinding.
