T1  - Restoring the spirit of fair play in the debate about violent video games a comment on Elson and Ferguson (2013)
T2  - EUROPEAN PSYCHOLOGIST
N2  - This commentary argues that, rather than providing an "exhaustive review," Elson and Ferguson (2013) discuss a selective sample of empirical studies on violent video game use which corroborate their claim that there is no systematic evidence for a link between violent video game play and aggression. In evaluating the evidence, the authors portray a biased picture of the current state of knowledge about media violence effects. They fail to distinguish between aggression and violence and between everyday and clinical forms of aggression. Furthermore, they misrepresent key constructs, such as mediation, moderation, and external validity, to discredit methodologies used to assess aggression and media violence use. The paper moves the debate backward rather than forward, falling behind existing meta-analytic studies that consider a much wider and more balanced range of studies.

T1  - Comment on "Bias correction, quantile mapping, and downscaling: revisiting the inflation issue"
T2  - Journal of climate
N2  - In a recent paper, Maraun describes the adverse effects of quantile mapping on downscaling. He argues that when large-scale GCM variables are rescaled directly to small-scale fields or even station data, genuine small-scale covariability is lost and replaced by uniform variability inherited from the larger scales. This leads to a misrepresentation mainly of areal means and long-term trends. This comment acknowledges the former point, although the argument is relatively old, but disagrees with the latter, showing that grid-size long-term trends can be different from local trends. Finally, because it is partly incorrectly addressed, some clarification is added regarding the inflation issue, stressing that neither randomization nor inflation is free of unverified assumptions.

T1  - When less equals more: probability summation without sensitivity improvement
T2  - Journal of experimental psychology : Human perception and performance
N2  - Many perceptual and cognitive tasks permit or require the integrated cooperation of specialized sensory channels, detectors, or other functionally separate units. In compound detection or discrimination tasks, 1 prominent general mechanism to model the combination of the output of different processing channels is probability summation. The classical example is the binocular summation model of Pirenne (1943), according to which a weak visual stimulus is detected if at least 1 of the 2 eyes detects this stimulus; as we review briefly, exactly the same reasoning is applied in numerous other fields. It is generally accepted that this mechanism necessarily predicts performance based on 2 (or more) channels to be superior to single channel performance, because 2 separate channels provide "2 chances" to succeed with the task. We argue that this reasoning is misleading because it neglects the increased opportunity with 2 channels not just for hits but also for false alarms and that there may well be no redundancy gain at all when performance is measured in terms of receiver operating characteristic curves. We illustrate and support these arguments with a visual detection experiment involving different spatial uncertainty conditions. Our arguments and findings have important implications for all models that, in one way or another, rest on, or incorporate, the notion of probability summation for the analysis of detection tasks, 2-alternative forced-choice tasks, and psychometric functions.

N2  - We argue that the theories of Volokitin and Persson (2014 New J. Phys. 16 118001), Dedkov and Kyasov (2008 J. Phys.: Condens. Matter 20 354006), and Pieplow and Henkel (2013 New J. Phys. 15 023027) agree on the electromagnetic force on a small, polarizable particle that is moving parallel to a planar, macroscopic body, as far as the contribution of evanescent waves is concerned. The apparent differences are discussed in detail and explained by choices of units and integral transformations. We point out in particular the role of the Lorentz contraction in the procedure used by Volokitin and Persson, where a macroscopic body is 'diluted' to obtain the force on a small particle. Differences that appear in the contribution of propagating photons are briefly mentioned.

T1  - Embedded operating system projects
N2  - In today’s life, embedded systems are ubiquitous. But they differ from traditional desktop systems in many aspects – these include predictable timing behavior (real-time), the management of scarce resources (memory, network), reliable communication protocols, energy management, special purpose user-interfaces (headless operation), system configuration, programming languages (to support software/hardware co-design), and modeling techniques. Within this technical report, authors present results from the lecture “Operating Systems for Embedded Computing” that has been offered by the “Operating Systems and Middleware” group at HPI in Winter term 2013/14. Focus of the lecture and accompanying projects was on principles of real-time computing. Students had the chance to gather practical experience with a number of different OSes and applications and present experiences with near-hardware programming. Projects address the entire spectrum, from bare-metal programming to harnessing a real-time OS to exercising the full software/hardware co-design cycle. Three outstanding projects are at the heart of this technical report. Project 1 focuses on the development of a bare-metal operating system for LEGO Mindstorms EV3. While still a toy, it comes with a powerful ARM processor, 64 MB of main memory, standard interfaces, such as Bluetooth and network protocol stacks. EV3 runs a version of 1 1 Introduction Linux. Sources are available from Lego’s web site. However, many devices and their driver software are proprietary and not well documented. Developing a new, bare-metal OS for the EV3 requires an understanding of the EV3 boot process. Since no standard input/output devices are available, initial debugging steps are tedious. After managing these initial steps, the project was able to adapt device drivers for a few Lego devices to an extent that a demonstrator (the Segway application) could be successfully run on the new OS. Project 2 looks at the EV3 from a different angle. The EV3 is running a pretty decent version of Linux- in principle, the RT_PREEMPT patch can turn any Linux system into a real-time OS by modifying the behavior of a number of synchronization constructs at the heart of the OS. Priority inversion is a problem that is solved by protocols such as priority inheritance or priority ceiling. Real-time OSes implement at least one of the protocols. The central idea of the project was the comparison of non-real-time and real-time variants of Linux on the EV3 hardware. A task set that showed effects of priority inversion on standard EV3 Linux would operate flawlessly on the Linux version with the RT_PREEMPT-patch applied. If only patching Lego’s version of Linux was that easy... Project 3 takes the notion of real-time computing more seriously. The application scenario was centered around our Carrera Digital 132 racetrack. Obtaining position information from the track, controlling individual cars, detecting and modifying the Carrera Digital protocol required design and implementation of custom controller hardware. What to implement in hardware, firmware, and what to implement in application software – this was the central question addressed by the project.
N2  - Heutzutage sind eingebettete Systeme allgegenwärtig. Allerdings unterscheiden sie sich in vielen Aspekten von traditionellen Desktop-System – dazu gehören vorhersagbares Zeitverhalten („Echtzeit“), die Verwaltung von knappen Ressourcen (Speicher, Netzwerk), zuverlässige Kommunikationsprotokolle, Energiemanagement, spezialisierte Benutzungsschnittstellen („headless“), Systemkonfiguration, Programmiersprachen (zur Unterstützung von Software-Hardware-Co-Design) und Modellierungstechniken. In diesem technischen Bericht präsentieren die Autoren Ergebnisse aus der Vorlesung „Betriebssysteme für Embedded Computing“, die von der Fachgruppe „Betriebssysteme und Middleware“ am HPI in Wintersemester 2013/14 angeboten wurde. Schwerpunkte der Vorlesung und der begleitenden Projekte waren Prinzipien von Echtzeit-Computing. Die Studenten hatten die Möglichkeit, praktische Erfahrungen mit einer Reihe von verschiedenen Betriebssystemen und Anwendungen zu sammeln und präsentieren ihre Erfahrungen mit hardwarenaher Programmierung. Die Projekte adressieren das gesamte Spektrum von der Bare-Metal-Programmierung über die Nutzung eines Echtzeitbetriebssystem bis zur Anwendung des vollen Software-Hardware-Co-Design-Zyklus‘. Drei herausragende Projekte sind das Herzstück dieses technischen Berichts. Projekt 1 konzentriert sich auf die Entwicklung eines Bare-Metal-Betriebssystems für LEGO Mindstorms EV3. Obwohl es ein Spielzeug ist, kommt es mit einem leistungsstarken ARM-Prozessor, 64 MB Hauptspeicher und Standardschnittstellen wie Bluetooth und einem Netzwerkprotokollstapel. Auf dem EV3 läuft spezielle Linux-Version – die Quellen sind auf der Lego-Website verfügbar. Allerdings sind viele Geräte und deren Treiber-Software urheberrechtlich geschützt und nicht gut dokumentiert. Die Entwicklung eines neuen Bare-Metal-Betriebssystem für den EV3 erfordert ein Verständnis des EV3-Bootvorgangs. Da keine Standard-Ein-/Ausgabegeräte zur Verfügung stehen, sind anfängliche Debug-Schritte mühsam. Nach dem Absolvieren dieser ersten Schritte war das Projekt in der Lage, Gerätetreiber für einige Lego-Geräte anzupassen um einen Demonstrator (die Segway-Anwendung) erfolgreich auf dem neuen Betriebssystem laufen zu lassen. Projekt 2 befasst sich mit dem EV3 aus einer anderen Perspektive. Der EV3 wird mit einer üblichen EV3 Linux-Version betrieben – im Prinzip kann der RT_PREEMPT-Patch jedes Linux-System in ein Echtzeitbetriebssystem verwandeln, indem er das Verhalten einer Anzahl von Synchronisationskonstrukten im Herzen des Betriebssystems anpasst. Priority Inversion ist ein Problem, das durch Protokolle wie Prioritätsvererbung oder Priority Ceiling gelöst wird. Heutige Echtzeit-Betriebssysteme implementieren mindestens eines dieser Protokolle. Die zentrale Idee des Projekts war der Vergleich der Nicht-Echtzeit und Echtzeit-Varianten von Linux auf der EV3-Hardware. Ein Task-Set, das die Auswirkungen der Prioritätsumkehr auf Standard-EV3 Linux zeigt, würde ohne Probleme auf der Linux-Version mit dem RT_PREEMPT-Patch betrieben werden können. Wenn nur das Patchen Lego-Version von Linux war so einfach wäre... Projekt 3 nimmt den Begriff des Echtzeit-Computing ernst. Das Anwendungsszenario wurde um unsere Carrera Digital 132 Bahn angeordnet. Das Sammeln von Positionsinformationen, die Steuerung einzelner Fahrzeuge, die Erfassung und Änderung des Carrera Digital-Protokolls erfordert die Konzeption und Umsetzung von spezialisierter Controller-Hardware. Die zentrale Fragestellung dieses Projekts war, was in Hardware, in Firmware oder in der Anwendungssoftware zu implementieren ist.

T1  - Path-dependent infinite-dimensional SDE with non-regular drift : an existence result
N2  - We establish in this paper the existence of weak solutions of infinite-dimensional shift invariant stochastic differential equations driven by a Brownian term. The drift function is very general, in the sense that it is supposed to be neither small or continuous, nor Markov. On the initial law we only assume that it admits a finite specific entropy. Our result strongly improves the previous ones obtained for free dynamics with a small perturbative drift. The originality of our method leads in the use of the specific entropy as a tightness tool and on a description of such stochastic differential equation as solution of a variational problem on the path space.

T1  - A solution selection problem with small stable perturbations
N2  - The zero-noise limit of differential equations with singular coefficients is investigated for the first time in the case when the noise is a general alpha-stable process. It is proved that extremal solutions are selected and the probability of selection is computed. Detailed analysis of the characteristic function of an exit time form on the half-line is performed, with a suitable decomposition in small and large jumps adapted to the singular drift.

T1  - Modified iterative Runge-Kutta-type methods for nonlinear ill-posed problems
N2  - This work is devoted to the convergence analysis of a modified Runge-Kutta-type iterative regularization method for solving nonlinear ill-posed problems under a priori and a posteriori stopping rules. The convergence rate results of the proposed method can be obtained under Hölder-type source-wise condition if the Fréchet derivative is properly scaled and locally Lipschitz continuous. Numerical results are achieved by using the Levenberg-Marquardt and Radau methods.

T1  - Reciprocal class of jump processes
N2  - Processes having the same bridges as a given reference Markov process constitute its reciprocal class. In this paper we study the reciprocal class of compound Poisson processes whose jumps belong to a finite set A in R^d. We propose a characterization of the reciprocal class as the unique set of probability measures on which a family of time and space transformations induces the same density, expressed in terms of the reciprocal invariants. The geometry of A plays a crucial role in the design of the transformations, and we use tools from discrete geometry to obtain an optimal characterization. We deduce explicit conditions for two Markov jump processes to belong to the same class. Finally, we provide a natural interpretation of the invariants as short-time asymptotics for the probability that the reference process makes a cycle around its current state.

T1  - Metastability of Morse-Smale dynamical systems perturbed by heavy-tailed Lévy type noise
N2  - We consider a general class of finite dimensional deterministic dynamical systems with finitely many local attractors each of which supports a unique ergodic probability measure, which includes in particular the class of Morse–Smale systems in any finite dimension. The dynamical system is perturbed by a multiplicative non-Gaussian heavytailed Lévy type noise of small intensity ε > 0. Specifically we consider perturbations leading to a Itô, Stratonovich and canonical (Marcus) stochastic differential equation. The respective asymptotic first exit time and location problem from each of the domains of attractions in case of inward pointing vector fields in the limit of ε-> 0 has been investigated by the authors. We extend these results to domains with characteristic boundaries and show that the perturbed system exhibits a metastable behavior in the sense that there exits a unique ε-dependent time scale on which the random system converges to a continuous time Markov chain switching between the invariant measures. As examples we consider α-stable perturbations of the Duffing equation and a chemical system exhibiting a birhythmic behavior.

T1  - Elliptic perturbations of dynamical systems with a proper node
N2  - The paper is devoted to asymptotic analysis of the Dirichlet problem for a second order partial differential equation containing a small parameter multiplying the highest order derivatives. It corresponds to a small perturbation of a dynamical system having a stationary solution in the domain. We focus on the case where the trajectories of the system go into the domain and the stationary solution is a proper node.

T1  - On the calibration of Lévy driven time series with coupling distances : an application in paleoclimate
N2  - This article aims at the statistical assessment of time series with large fluctuations in short time, which are assumed to stem from a continuous process perturbed by a Lévy process exhibiting a heavy tail behavior. We propose an easily implementable procedure to estimate efficiently the statistical difference between the noisy behavior of the data and a given reference jump measure in terms of so-called coupling distances. After a short introduction to Lévy processes and coupling distances we recall basic statistical approximation results and derive rates of convergence. In the sequel the procedure is elaborated in detail in an abstract setting and eventually applied in a case study to simulated and paleoclimate data. It indicates the dominant presence of a non-stable heavy-tailed jump Lévy component for some tail index greater than 2.

T1  - Singular perturbations of elliptic operators
N2  - We develop a new approach to the analysis of pseudodifferential operators with small parameter 'epsilon' in (0,1] on a compact smooth manifold X. The standard approach assumes action of operators in Sobolev spaces whose norms depend on 'epsilon'. Instead we consider the cylinder [0,1] x X over X and study pseudodifferential operators on the cylinder which act, by the very nature, on functions depending on 'epsilon' as well. The action in 'epsilon' reduces to multiplication by functions of this variable and does not include any differentiation. As but one result we mention asymptotic of solutions to singular perturbation problems for small values of 'epsilon'.
