A1 - Käs, Josef T1 - Emergent complexity of the cytoskeleton: from single filaments to tissue JF - Advances in Physics N2 - Despite their overwhelming complexity, living cells display a high degree of internal mechanical and functional organization which can largely be attributed to the intracellular biopolymer scaffold, the cytoskeleton. Being a very complex system far from thermodynamic equilibrium, the cytoskeleton's ability to organize is at the same time challenging and fascinating. The extensive amounts of frequently interacting cellular building blocks and their inherent multifunctionality permits highly adaptive behavior and obstructs a purely reductionist approach. Nevertheless (and despite the field's relative novelty), the physics approach has already proved to be extremely successful in revealing very fundamental concepts of cytoskeleton organization and behavior. This review aims at introducing the physics of the cytoskeleton ranging from single biopolymer filaments to multicellular organisms. Throughout this wide range of phenomena, the focus is set on the intertwined nature of the different physical scales (levels of complexity) that give rise to numerous emergent properties by means of self-organization or self-assembly.

T1 - Spec2Vec: Improved mass spectral similarity scoring through learning of structural relationships JF - PLOS Computational Biology N2 - Spectral similarity is used as a proxy for structural similarity in many tandem mass spectrometry (MS/MS) based metabolomics analyses such as library matching and molecular networking. Although weaknesses in the relationship between spectral similarity scores and the true structural similarities have been described, little development of alternative scores has been undertaken. Here, we introduce Spec2Vec, a novel spectral similarity score inspired by a natural language processing algorithm-Word2Vec. Spec2Vec learns fragmental relationships within a large set of spectral data to derive abstract spectral embeddings that can be used to assess spectral similarities. Using data derived from GNPS MS/MS libraries including spectra for nearly 13,000 unique molecules, we show how Spec2Vec scores correlate better with structural similarity than cosine-based scores. We demonstrate the advantages of Spec2Vec in library matching and molecular networking. Spec2Vec is computationally more scalable allowing structural analogue searches in large databases within seconds.

The actin bundle network is conductive to travelling excitations, i.e. impulses. The machine is interfaced with an arbitrary selected set of k electrodes through which stimuli, binary strings of length k represented by impulses generated on the electrodes, are applied and responses are recorded. The responses are recorded in a form of impulses and then converted to binary strings. The machine's state is a binary string of length k: if there is an impulse recorded on the ith electrode, there is a '1' in the ith position of the string, and '0' otherwise. We present a design of the machine and analyse its state transition graphs. We envisage that actin droplet machines could form an elementary processor of future massive parallel computers made from biopolymers.

These travelling localisations can be utilised to generate computing circuits from actin networks. The propagation of localisations on a single actin filament is experimentally unfeasible to control. Therefore, we consider excitation waves propagating on bundles of actin filaments. In computational experiments with a two-dimensional slice of an actin bundle network we show that by using an arbitrary arrangement of electrodes, it is possible to implement two-inputs-one-output circuits.

While the formation of the lamellipodium is increasingly well understood, organizational principles underlying the emergence of the lamellum are just beginning to be unraveled. We report here on a 1D mathematical model which describes the reaction-diffusion processes of a polarized actin network in steady state, and reproduces essential characteristics of the lamellipodium-lamellum system. We observe a steep gradient in filament lengths at the protruding edge, a local depolymerization maximum a few microns behind the edge, as well as a differential dominance of the network destabilizer ADF/cofilin and the stabilizer tropomyosin. We identify simple and robust organizational principles giving rise to the derived network characteristics, uncoupled from the specifics of any molecular implementation, and thus plausibly valid across cell types. An analysis of network length dependence on physico-chemical system parameters implies that to limit array treadmilling to cellular dimensions, network growth has to be truncated by mechanisms other than aging-induced depolymerization, e.g., by myosin-associated network dissociation at the transition to the cell body. Our work contributes to the analytical understanding of the cytoskeletal extension's bisection into lamellipodium and lamellum and sheds light on how cells organize their molecular machinery to achieve motility.

Bei korrekter Anwendung dieser APIs können mit ihnen sensible System- und Benutzerdaten vor Angriffen geschützt werden. Bisher gibt es nur wenige verfügbare Tool-basierte Hilfsmittel für Programmierer, welche die Verwendungsfehler identifzieren können. Für die Programmiersprache Java konnten bislang nur sehr wenige dieser spezialisierten Hilfsmittel gefunden werden, darunter das statische Codeanalysetool CogniCrypt. Ein derartiges Werkzeug für C# konnte nicht gefunden werden. Diese Arbeit befasst sich mit der Entwicklung eines Plugins für die IDE Visual Studio zur statischen Codeanalyse namens Sharper Crypto-API Analysis. Sein Hauptziel ist, Programmierern beim Verwenden der .NET Krypto-API mit der Programmiersprache C# zu unterstützen. Durch Beobachtungen im Entwicklungsprozess sollen einerseits die Parallelen und Unterschiede zwischen der Java- und der C#-Welt im Umgang mit Krypto-APIs erkennbar werden. Andererseits beschreibt diese Arbeit den erforderlichen Aufwand, um ein hoch spezialisiertes, statisches Codeanalysetool zu entwickeln. Die Beobachtungen zeigen, dass die Unterschiede der Java- und C#-Technologien nicht oberflächlich, sondern hauptsächlich im Detail liegen und daher während der Implementierung des Tools besondere Aufmerksamkeit erfordern. Die Entwicklungsphase selbst zeigt sich als besonders anspruchsvoll, da mit Unsicherheitsfaktoren bezüglich der Funktions- und Verhaltensweisen von Visual Studio umgegangen werden müssen. Das Hauptziel von Sharper Crypto-API Analysis konnte durch die Implementation von vier Hauptfunktionsgruppen umgesetzt werden. Die wichtigste von ihnen ist das Bereitstellen von Codeanalysen, welche ausschließlich auf die Verwendung der .NET Krypto-API spezialisiert sind. Die hier entwickelten Codeanalysen betrachten besonders Fehlerquellen, die Programmierer am häufigsten begehen. Um den Programmierern nachhaltig Wissen bezüglich der Krypto-API zu vermitteln, führt diese Arbeit erweiterte Analyseberichte ein, die zusätzlich über Schwachstellen oder Angriffsszenarien informieren. Besonderheiten und Alleinstellungsmerkmale der anderen Funktionsgruppen werden in dieser Arbeit unter besonderer Berücksichtigung von Implementationshinweisen dokumentiert. N2 - Recent researches have shown that up to 95% of all available Andriod Apps contain at least one programming error caused by wrongly applying so-called Crypto-APIs. By using these APIs, applications can ensure protection of sensitive data against attacks. Currently there is a very limited amount of program-based tools available which help programmers identifying their mistakes in using Crypto-APIs. The programming language Java seems to be most prominent as many of the few tools found are specialized for this language. One of them is called CogniCrypt. A specialized tool for the C# programming language however could not be found. The thesis at hand addresses the development of a static code analysis plugin for the IDE Visual Studio called Sharper Crypto-API Analysis. To assist programmers using the .NET Crypto-API in C# shall be its main goal. Observations during the development process shall point out differences between the Java and C# ecosystems in handling Crypto-APIs. Furthermore the work at hand describes the necessary expenditure to develop a static code analysis tool. On the one hand the observations show differences between Java and C#, which only become obvious after a careful examination. Hence, attention must be paid during the implmentation of the tool. On the other hand the development process revealed itsself to be challenging because of unpredictable and undocumented behaviour of the host platform Visual Studio. The main goal of Sharper Crypto-API Analysis could be achieved by implementing four primary function classes. The most important class contains code analyzers which investigate exspecially the usage of the .NET Crypto-API. In particular the analysis specialized at errors which programmers tend to do most commonly. In addition to analyzing bare source code the tool also presents more detailed reports that shall help programmers to understand weaknesses and attacks their code allows to perform and most importantly how to fix the identified issues. Lastly this work will also document the other function classes and point out their features and behaviours with a special consideration on implementation details.

Thus, we argue that, on a perceptual level, reverberation basically breaks down into interaural differences and spectro-temporal cues and that the separation of a perceived timbre into a sound source and a surrounding room is a purely cognitive process. To investigate the connection between the perception of reverberation cues and timbre analysis, the sensitivity for changes in reverberation was compared to timbre perception abilities. The Timbre Perception Test was used to measure the perception of the temporal envelope, spectral centroid, and spectral flux of artificial sounds. Sensitivity for changes in reverberation time was tested with a discrimination task using speech and noise with speech-alike spectral and temporal envelopes as source signals. Musical and acoustical expertise was assessed through the Goldsmiths Musical Sophistication Index and self-reports on experience with and knowledge of acoustics. There was a considerable correlation between timbre and reverberance perception ability, but timbre perception and academic experience predicted only 41% of the variance in reverberance perception. Still, perception abilities related to similar acoustical phenomena seem to be better indicators of listening skills than self-reports on acoustical or musical expertise.

Continuous Delivery bietet in der agilen Softwareentwicklung mit kurzen Entwicklungszyklen die Antwort auf diesen Wandel. Die Verwendung einer Continuous Delivery-Umgebung (CD-Umgebung) erfordert einerseits zwar einen initialen Einrichtungsaufwand. Andererseits kann durch den Einsatz einer CD-Umgebung das gesamte Projekt an Schnelligkeit gewinnen. In Kombination mit Microservice-Architekturen lassen sich kleine Deployment-Einheiten umsetzen. Microservice-Architekturen bringen einen Mehrwert durch Flexibilität, Skalierung, Automatisierung, standardisierte Schnittstellen und Ausfallsicherheit. Microservices fungieren autark in verteilten Systemen und weisen nur sehr geringe Abhängigkeiten zu anderen Services auf. Die Kommunikation findet über einheitliche Schnittstellen statt, weshalb Implementierungsdetails der Microservices nach außen betrachtet irrelevant sind. Für die Umsetzung der CD-Umgebung wird der web-basierte Git-Repository-Manager GitLab in Kombination mit der Container-Orchestrierungsplattform Kubernetes verwendet, da sich beide Programme einfach integrieren lassen. Innerhalb eines Tutorials wird, basierend auf Best Practices anhand des Beispiels der HSD-Card, erläutert wie eine Microservice-Architektur mit Spring Boot, als Anwendung umgesetzt werden kann. Für die Erstellung der Microservice-Architektur legt das Tutorial Schwerpunkte auf die Verwendung von Software Design Pattern (DDD), die Struktur innerhalb Spring Boot, die Kommunikation via REST sowie die Skalierung, das Load-Balancing und die Überführung in die CD-Umgebung.

These are web applications with “super-powers” which are meant to provide the kinds of user experiences previously only native mobile applications could. Therefore they are able to match native applications in their capabilities but still thrive on the reachability of the web. They achieve this by implementing certain characteristics which originate from innovative standards and sophisticated best practices. Conveniently, as it is the web, PWAs are working seamlessly cross-platform. One of the closest things to a PWA so far may be an application created with the NativeScript framework. Such an application is also developed with web technologies yet able to use any native interface directly. This is made possible by using a designated runtime for mediating between JavaScript and the mobile system. Eventually, NativeScript is able to offer a high degree nativity yet also of convenient abstraction during development. This paper is set out to deliver further insight into both approaches by contrasting them based on the characteristics of PWAs. For this purpose, these characteristics are elaborated and adjusted to be applicable to native mobile applications. Hence a reasonable basis for what to expect from a native application is derived. Then NativeScript is assessed on this basis by the means of transferable concepts and technologies as well as a prototypic mobile application. Finally, an informed discussion and conclusion is performed based on the results. The comprehensive characteristics of PWAs resolve previous shortcomings with well thought out concepts and new technologies. These are transferable to native mobile applications to a far extent and may also be put into practice with NativeScript. The framework’s approach may be very well called ingenious, however, in the long run it might fall short of the innovative concept of PWAs. Having said this, it is still able to serve as a practical measure for creating appealing user experiences for multiple systems with arguably little effort. Due to large overlap a transformation between the two application types is a realistic option. Either way, web technologies are far from what they used to be and it is exciting to see how the mobile and web landscape will evolve in the future.

In a virtual (tv) studio talents could be overburden by interaction tasks because camera and text require extensive attention. We take a look into animations and inter- actions within a studio, which do not require any special attention or learning. We show the generation of an artificial shadow from a talent, which ease the keying process, where separation of real shadows from the background is a difficult task. We also demonstrate animations of footsteps and dust. Furthermore, capturing talents’ height can also be used to adjust the parameters of elements in the virtual environment, like the position and scaling of a virtual display. In addition to the talents, a rigid body was tracked as placeholder for graphics, easing the interaction tasks for a talent. Two test productions show the possibilities, which subtle animations offer. In the second production, the rendering was improved (shadows, filtering, normal maps, ...) and instead of using the rigid body to move an object (a flag), the animation was only controlled by the hand’s position.
