description: We use machine learning tools to model the line interaction of failure cascading in power grid networks. We first collect data sets of simulated trajectories of possible consecutive line failure following an initial random failure and considering actual constraints in a model power network until the system settles at a steady state. We use weighted $l_1$-regularized logistic regression-based models to find static and dynamic models that capture pairwise and latent higher-order lines' failure interactions using pairwise statistical data. The static model captures the failures' interactions near the steady states of the network, and the dynamic model captures the failure unfolding in a time series of consecutive network states. We test models over independent trajectories of failure unfolding in the network to evaluate their failure predictive power. We observe asymmetric, strongly positive, and negative interactions between different lines' states in the network. We use the static interaction model to estimate the distribution of cascade size and identify groups of lines that tend to fail together, and compare against the data. The dynamic interaction model successfully predicts the network state for long-lasting failure propagation trajectories after an initial failure.

description: The quantum kicked rotor (QKR) model is a prototypical system in the research of quantum chaos. In a spin-$1/2$ QKR, tuning the effective Planck parameter realizes a series of transitions between dynamical localization phases, which closely resembles the integer quantum Hall (IQH) effect and the plateau transitions. In this work, we devise and apply the finite-size scaling analysis to the transitions in the spin-$1/2$ QKR model. We obtain an estimate of the critical exponent at the transition point, $ν=2.62(9)$, which is consistent with the IQH plateau transition universality class. We also give a precise estimate of the universal diffusion rate at the metallic critical state, $σ^{*}=0.3253(12)$.

description: In the 3-week term June 2010 we have worked with Nano Imprint Lithography (NIL) in the course 33422. NIL is a nonconventional lithographic technique for high-throughput patterning of polymer nanostructures at great precision and at low costs. NIL relies on direct mechanical deformation of the resist material and can therefore achieve resolutions beyond the limitations set by light diffraction or beam scattering that are encountered in conventional techniques. In this presentation we will present NIL as an energy efficient and environmental friendly technology compared to traditional micro and nano fabrication approaches. We will introduce NIL and describe why it can be considered a green technology.

description: We explore the prospect of constraining light mediators at the next generation direct detection dark matter detectors through coherent elastic neutrino-nucleus scattering (CE$ν$NS) and elastic neutrino-electron scattering (E$ν$ES) measurements. Taking into account various details like the quenching factor corrections, atomic binding effects, realistic backgrounds, detection efficiency, energy resolution etc., we consider two representative scenarios regarding detector specifications. For both scenarios, we obtain the model-independent projected sensitivities for all possible Lorentz-invariant interactions, namely scalar ($S$), pseudoscalar ($P$), vector ($V$), axial vector ($A$) and tensor ($T$). For the case of vector interactions, we also focus on two concrete examples: the well-known $U(1)_{B-L}$ and $U(1)_{L_μ- L_τ}$ gauge symmetries. For all interaction channels $X=\{S,P,V,A,T\}$, our results imply that the upcoming dark matter detectors have the potential to place competitive constraints, improved by about 1 order of magnitude compared to existing ones from dedicated CE$ν$NS experiments, XENON1T, beam dump experiments and collider probes.

description: Among all fluids, water has always been of special concern for scientists from a broad variety of research fields due to its rich behavior. In particular, some questions remain unanswered nowadays concerning the temperature dependence of bulk and interfacial transport properties of supercooled and liquid water, e.g. regarding the fundamentals of the violation of the Stokes-Einstein relation in the supercooled regime or the subtle relation between structure and dynamical properties. Here we investigated the temperature dependence of the bulk transport properties from ab initio molecular dynamics based on density functional theory, down to the supercooled regime. We determined from a selection of functionals, that SCAN better describes the experimental viscosity and self-diffusion coefficient, although we found disagreements at the lowest temperatures. For a limited set of temperatures, we also explored the role of nuclear quantum effects on water dynamics using ab initio molecular dynamics that has been accelerated via a recently introduced machine learning approach. We then investigated the molecular mechanisms underlying the different functionals performance and assessed the validity of the Stokes-Einstein relation. We also explored the connection between structural properties and the transport coefficients, verifying the validity of the excess entropy scaling relations for all the functionals. These results pave the way to predict the transport coefficients from the radial distribution function, helping to develop better functionals. On this line, they indicate the importance of describing the long-range features of the radial distribution function.

description: We explore the use of Deep Learning to infer the temperature of the intergalactic medium from the transmitted flux in the high redshift Lyman-alpha forest. We train Neural Networks on sets of simulated spectra from redshift z=2-3 outputs of cosmological hydrodynamic simulations, including high temperature regions added in post-processing to approximate bubbles heated by Helium-II reionization. We evaluate how well the trained networks are able to reconstruct the temperature from the effect of Doppler broadening in the simulated input Lyman-alpha forest absorption spectra. We find that for spectra with high resolution (10 km/s pixel) and moderate signal to noise (20-50), the neural network is able to reconstruct the IGM temperature smoothed on scales of 6 Mpc/h quite well. Concentrating on discontinuities we find that high temperature regions of width 25 Mpc/h and temperature 20,000 K can be fairly easily detected and characterized. We show an example where multiple sightlines are combined to yield tomographic images of hot bubbles. Deep Learning techniques may be useful in this way to help us understand the complex temperature structure of the intergalactic medium around the time of Helium reionization.

Assessment of [Fe/H] determinations for FGK stars in spectroscopic surveys

description: The number of stars with a measured value of [Fe/H] is considerably increasing thanks to spectroscopic surveys. However different methodologies, inputs and assumptions used in spectral analyses lead to different precisions in [Fe/H] and possibly to systematic differences that need to be evaluated. It is essential to understand the characteristics of each survey to fully exploit their potential, in particular if the surveys are combined. The purpose of this study is to compare [Fe/H] determinations from the largest spectroscopic surveys (APOGEE, GALAH, the Gaia ESO survey, RAVE, LAMOST, SEGUE ) to other catalogues taken as reference. Offsets and dispersions of the residuals are examined as well as their trends with other parameters. We use reference samples providing independent determinations of [Fe/H] which are compared to those from the surveys for common stars. The distribution of the residuals is assessed through simple statistics that measures the offset between two catalogues and the dispersion representative of the precision of both catalogues. When relevant, linear fits are performed. A large sample of FGK-type stars with [Fe/H] based on high-resolution, high signal to noise spectroscopy was built from the PASTEL catalogue to provide a reference sample. We also use FGK members in open and globular clusters to assess the internal consistency of [Fe/H] of each survey. The agreement of median [Fe/H] values for clusters observed by different surveys is discussed. All the surveys overestimate the low metallicities, and some of them also underestimate the high metallicities. They perform well in the most populated intermediate metallicity range, whatever the resolution. In most cases the typical precision that we deduce from the comparisons is in good agreement with the uncertainties quoted in the catalogues. Some exceptions to this general behaviour are discussed.

description: Observations have shown that the star-formation activity and the morphology of galaxies are closely related, but the underlying physical connection is not well understood. Using the TNG50 simulation, we explore the quenching and the morphological evolution of the 102 massive quiescent galaxies in the mass range of $10.5<\log(M_{\rm stellar}/M_{\odot})<11.5$ selected at $z=0$. The morphology of galaxies is quantified based on their kinematics, and we measure the quenching timescale of individual galaxies directly from star formation history. We show that galaxies tend to be quenched more rapidly if they: (i) are satellites in massive halos, (ii) have lower star-forming gas fractions, or (iii) inject a larger amount of black hole kinetic feedback energy. By following the global evolutionary pathways, we conclude that quiescent discs are mainly disc galaxies that are recently and slowly quenched. Approximately half of the quiescent ellipticals at $z=0$ are rapidly quenched at higher redshifts while still disc-like. While being quiescent, they gradually become more elliptical mostly by disc heating, yet these ellipticals still retain some degree of rotation. The other half of quiescent ellipticals with the most random motion-dominated kinematics build up large spheroidal components before quenching primarily by mergers, or in some cases, misaligned gas accretion. However, the mergers that contribute to morphological transformation do not immediately quench galaxies in many cases. In summary, we find that quenching and morphological transformation are decoupled. We conclude that the TNG black hole feedback -- in combination with the stochastic merger history of galaxies -- leads to a large diversity of quenching timescales and a rich morphological landscape.

description: In recent years, the concept of energy harvesting has attracted much attention. The basic idea is to scavenge or harvest energy from the ambient surroundings of a device, convert it into electrical energy and use it to power a device, typically a wireless sensor system. The energy harvester can thus be seen as a small local power plant which uses otherwise wasted energy in the form of vibrations, temperature differences etc. which are abundant in most systems. By creating energy harvesters of the same size as modern batteries, the technology therefore has the fascinating future prospect of making batteries redundant. This is therefore a green technology that can be integrated in a wide range of systems, making it highly interesting.

description: Aus der Literatur und den geführten Interviews geht hervor, dass die Rolle des Gatewatchers,
            welche in der Beobachtung der Ausgangstore bei Nachrichtenprozessen
            liegt, eine Zusatzaufgabe zum Gatekeeper darstellen kann oder diesen ersetzt. Eine
            immer stärker aufkommende Daten- und Informationsflut durch das Internet verändert
            die Arbeitsweise der Journalistinnen und Journalisten zunehmend. Ist die Aufgabe
            des Gatekeepers, die in der Kontrollfunktion des Informationsflusses liegt, überhaupt
            noch zeitgerecht, wandelt diese sich zur Funktion des Gatewatchers um, oder
            kommt es zu einer Fusion von Beiden? Im folgenden Beitrag wird aufgezeigt, wieso
            Informationsschleusen noch notwendig sind und dass, die Funktion des Gatekeepers
            als auch des Gatewatchers essentielle Aufgaben des Journalismus darstellen. Des Weiteren
            wird auf die Diskrepanz in Literatur und Praxis, in Bezug auf die Entwicklung
            des Gatekeepers eingegangen. Dabei sind sich sowohl die Wissenschaft als auch die
            Praxis uneinig, ob Gatewatching eine Zusatzaufgabe zum Gatekeeping darstellt oder
            die Funktion des Gatekeepers ablöst.
description: The literature and the conducted interviews illustrate that journalists themselves assume,
            that the role of the Gatewatcher, which depends on the observation of output
            ports in message processing, may constitute an additional task to the Gatekeeper
            function or replace it. Due to the rise of the data- and information flow throughout the
            internet, the duties and ways of working in the journalists sector change. Is the task of
            gatekeeping, which matters in the control function of the flow of information, still a
            timely manner, does it transform into the function of gatewatching or is the coexistence
            of both possible? This article demonstrates the need of Gates, and that both,
            Gatekeeper as well as Gatewatcher, are important in journalism. Furthermore, the study discusses the discrepancy of literature and practice in relation to the advancement of gatekeeping. Thereby, science as well as practice, are at odds with themselves wether gatewatching is an additional task to the gatekeeping function, or replaces it.

description: We introduce a numerical method to determine the Hamiltonian of Mean Force (HMF) Gibbs state for a quantum system strongly coupled to a reservoir. The method adapts the Time Evolving Matrix Product Operator (TEMPO) algorithm to imaginary time propagation. By comparing the real-time and imaginary-time propagation for a generalized spin-boson model, we confirm that the HMF Gibbs state correctly predicts the steady state. We show that the numerical dynamics match the polaron master equation at strong coupling. We illustrate the potential of the imaginary-time TEMPO approach by exploring reservoir-induced entanglement between qubits.

            platforms, the Radiofabrik Salzburg and FS1 Salzburg. The interviews with show creators
            and trainers provide valuable information on the production and the intentions
            of participatory media. The involvement of the audience is common to both participatory media and the new
            news process. Platforms such as the Radiofabrik Salzburg and FS1 Salzburg can serve
            as a supplement to classic journalism.

description: We report magneto-optical trapping (MOT) of a polyatomic molecule, calcium monohydroxide (CaOH). The MOT contains $2.0(5)\times 10^4$ CaOH molecules at a peak density of $3.0(8)\times10^{6}$ cm$^{-3}$. CaOH molecules are further sub-Doppler laser cooled in an optical molasses, to a temperature of 110(4) $μ$K. The temperatures and densities achieved here make CaOH a viable candidate for a wide variety of quantum science applications, including the creation of optical tweezer arrays of CaOH molecules. This work also suggests that laser cooling and magneto-optical trapping of many other polyatomic species will be both feasible and practical.

description: This report describes the steps for properly sizing and selecting, depending on expected performance, safety and operators training, the DC components that will be integrated in the Terni Pilot infrastructure. The demonstrator in Terni is aiming at achieving the HYPERRIDE objectives, demonstrating the benefits over the conventional Alternating Current (AC) grids. especially by the integrating renewables in hybrid AC/DC grids. This is enabling the identification of solutions to overcome barriers for a successful roll-out of new infrastructure concepts throughout Europe. The proposed configuration and list of components will be based on the targeted functional features of the Terni demonstrator, previously defined, and will be used for the system level modeling and simulation, in Task 4.2 “LVDC virtual microgrid model and simulation”, in WP4.

description: The development of an optimal process technology for second generation bioethanol production (biological route) is still one of the major challenges facing the green production of biofuels. It is a huge technology and engineering challenge from the process design and operation point of view. This course takes on this challenge and will search for the optimization of one conventional bioethanol process flowsheet. The course will use dynamic plant model simulations to generate innovative solutions. The course will look for an optimal production of the biofuel by identifying, manipulating and fine-tuning the most critical variables presented in the complete production process.

description: The 4.2$σ$ discrepancy between the standard model prediction for the muon anomalous magnetic moment $a_μ$ and the experimental result is accompanied by other anomalies. A crucial input for the prediction is the hadronic vacuum polarization $a_μ^{\rm HVP}$ inferred from $σ_{\rm had} =σ(e^+e^- \to\,$hadrons) data. However, the two most accurate determinations of $σ_{\rm had}$ from KLOE and BaBar disagree by almost 3$\,σ$. Additionally, the combined data-driven result disagrees with the most precise lattice determination of $a_μ^{\rm HVP}$ by $2.1\,σ$. We show that all these discrepancies could be accounted for by a new boson produced resonantly around the KLOE centre of mass energy and decaying promptly yielding $e^+e^-$ and $μ^+μ^-$ pairs in the final states. This gives rise to three different effects: (i) the additional $e^+e^-$ events will affect the KLOE luminosity determination based on measurements of the Bhabha cross section, and in turn the inferred value of $σ_{\rm had}$; (ii) the additional $μ^+μ^-$ events will affect the determination of $σ_{\rm had}$ via the (luminosity independent) measurement of the ratio of $π^+π^-γ$ versus $μ^+μ^-γ$ events; (iii) loops involving the new boson would contribute directly to the prediction for $a_μ$. We discuss in detail this possibility, and we present a simple model that can reconcile the KLOE and BaBar results for $σ_{\rm had}$, the data-driven and the lattice determinations of $a_μ^{\rm HVP}$, the predicted and measured values of $a_μ$, while complying with all phenomenological constraints.

description: Magnetic refrigeration is an alternative to conventional refrigeration. Where conventional refrigeration uses vapor compression cycles, magnetic refrigeration is based on the magnetocaloric effect, i.e. the property of magnetic materials to change temperature when exposed to a changing magnetic field. The technology is currently used for low temperature cooling (<10K). By implementing stacks of magnetic plates instead of powder, it can be optimized to yield a more energy efficient room temperature cooling than conventional refrigeration. This project investigates the configuration of the stacks in order to get the largest temperature change with as little material and energy costs as possible.

description: We study the verification problem for closed-loop dynamical systems with neural-network controllers (NNCS). This problem is commonly reduced to computing the set of reachable states. When considering dynamical systems and neural networks in isolation, there exist precise approaches for that task based on set representations respectively called Taylor models and zonotopes. However, the combination of these approaches to NNCS is non-trivial because, when converting between the set representations, dependency information gets lost in each control cycle and the accumulated approximation error quickly renders the result useless. We present an algorithm to chain approaches based on Taylor models and zonotopes, yielding a precise reachability algorithm for NNCS. Because the algorithm only acts at the interface of the isolated approaches, it is applicable to general dynamical systems and neural networks and can benefit from future advances in these areas. Our implementation delivers state-of-the-art performance and is the first to successfully analyze all benchmark problems of an annual reachability competition for NNCS.

description: I benefici che l’attività motoria opera sia nell’età adulta che durante l’infanzia sono molteplici. Tra questi, si annoverano i miglioramenti delle abilità percettive, attentive e mnestiche. Lo scopo del presente lavoro è verificare se le capacità mnestiche ed attentive possano essere incrementate dalla messa in opera di un’offerta formativa specifica. Due gruppi di bambini, di età compresa  tra i sei e i dieci anni sono stati avviati al gioco della pallavolo. Un gruppo è stato allenato con un metodo che carica di significati i movimenti corporei dell’allenatore e dei compagni al fine di associare tali movimenti allo svolgimento di future indicazioni da eseguire (Pittera, Pedata e Ligas, 2008). L’altro gruppo ha svolto esercizi propedeutici alla pallavolo attraverso la focalizzazione sull’apprendimento dei gesti tecnici. La differenza tra i dati raccolti all’inizio e alla fine del periodo di allenamento preso in esame evidenziarono un miglioramento della capacità di ricordare azioni motorie; nessun miglioramento apparve però per quanto ha riguardato il numero di posizioni spaziali o il numero di componenti verbali da ricordare. Sorprendentemente, poi, nessun miglioramento emerse nelle misure di attenzione sostenuta. I risultati suggeriscono come, focalizzando l’attenzione dei discenti sugli aspetti motori dell’esercizio, e facendo in modo che questi aumentino di significato al fine della successiva realizzazione di nuovi compiti, si possa aumentare una capacità basilare di ogni apprendimento sportivo, ovvero la capacità di ricordare nuove azioni.
