description: The increasing demand for flexibility of automated production systems also affects the automated material flow systems (aMFS) they contain and demands reconfigurable systems. However, the centralized control concept usually applied in aMFS hinders an easy adaptation, as the entire control software has to be re-tested, when manually changing sub-parts of the control. As adaption and subsequent testing are a time-consuming task, concepts for splitting the control from one centralized to multiple, decentralized control nodes are required. Therefore, this paper presents a holistic agent-based control concept for aMFS, whereby the system is divided into so-called automated material flow modules (aMFM), each being controlled by a dedicated module agent. The concept allows the reconfiguration of aMFS, consisting of heterogeneous, stationary aMFM, during runtime. Furthermore, it includes aspects such as uniform agent knowledge bases through metamodel-based development, a communication ontology considering different information types and properties, strategic route optimization in decentralized control architecture and a visualization concept to make decisions of the module agents comprehensible to operators and maintenance staff. The evaluation of the concept is performed by means of material flow simulations as well as a prototypical implementation on a lab-sized demonstrator.

description: The letter addresses misattribution of the discovery of the classical equation for spin motion in electromagnetic field, known as the BMT equation, named after Bargmann, Michel, and Telegdi. I argue that J. (or Ya.) Frenkel, along with L. H. Thomas, should be considered as a co-discoverer of this equation. He first derived it, in another form, in 1926.

description: When changes are performed on an automated production system (aPS), new faults can be accidentally introduced in the system, which are called regressions. A common method for finding these faults is regression testing. In most cases, this regression testing process is performed under high time pressure and on-site in a very uncomfortable environment. Until now, there is no automated support for finding and prioritizing system test cases regarding the fully integrated aPS that are suitable for finding regressions. Thus, the testing technician has to rely on personal intuition and experience, possibly choosing an inappropriate order of test cases, finding regressions at a very late stage of the test run. Using a suitable prioritization, this iterative process of finding and fixing regressions can be streamlined and a lot of time can be saved by executing test cases likely to identify new regressions earlier. Thus, an approach is presented in this paper that uses previously acquired runtime data from past test executions and performs a change identification and impact analysis to prioritize test cases that have a high probability to unveil regressions caused by side effects of a system change. The approach was developed in cooperation with reputable industrial partners active in the field of aPS engineering, ensuring a development in line with industrial requirements. An industrial case study and an expert evaluation were performed, showing promising results.

description: Edge computing is becoming more and more popular among researchers who seek to take advantage of the edge resources and the minimal time delays, in order to run their robotic applications more efficiently. Recently, many edge architectures have been proposed, each of them having their advantages and disadvantages, depending on each application. In this work, we present two different edge architectures for controlling the trajectory of an Unmanned Aerial Vehicle (UAV). The first architecture is based on docker containers and the second one is based on kubernetes, while the main framework for operating the robot is the Robotic Operating System (ROS). The efficiency of the overall proposed scheme is being evaluated through extended simulations for comparing the two architectures and the overall results obtained.

description: A stochastic Gross-Pitaevskii equation is derived for partially condensed Bose gas systems subject to binary contact interactions. The theory we present provides a classical-field theory suitable for describing dissipative dynamics and phase transitions of spinor and multi-component Bose gas systems comprised of an arbitrary number of distinct interacting Bose fields. A new class of dissipative processes involving distinguishable particle interchange between coherent and incoherent regions of phase-space is identified. The formalism and its implications are illustrated for two-component mixtures and spin-1 Bose-Einstein condensates. For systems comprised of atoms of equal mass, with thermal reservoirs that are close to equilibrium, the dissipation rates of the theory are reduced to analytical expressions that may be readily evaluated. The unified treatment of binary contact interactions presented here provides a theory with broad relevance for quasi-equilibrium and far-from-equilibrium Bose-Einstein condensates.

description: Provenance for database queries or scientific workflows is often motivated as providing explanation, increasing understanding of the underlying data sources and processes used to compute the query, and reproducibility, the capability to recompute the results on different inputs, possibly specialized to a part of the output. Many provenance systems claim to provide such capabilities; however, most lack formal definitions or guarantees of these properties, while others provide formal guarantees only for relatively limited classes of changes. Building on recent work on provenance traces and slicing for functional programming languages, we introduce a detailed tracing model of provenance for multiset-valued Nested Relational Calculus, define trace slicing algorithms that extract subtraces needed to explain or recompute specific parts of the output, and define query slicing and differencing techniques that support explanation. We state and prove correctness properties for these techniques and present a proof-of-concept implementation in Haskell.

description: The presence of neutral C60 fullerenes in circumstellar environments has been firmly established by astronomical observations as well as laboratory experiments and quantum-chemistry calculations. However, the large variations observed in the C60 17.4um/18.9um band ratios indicate that either additional emitters should contribute to the astronomical IR spectra or there exist unknown physical processes besides thermal and UV excitation. Fullerene-based molecules such as metallofullerenes and fullerene-adducts are natural candidate species as potential additional emitters, but no specific species has been identified to date. Here we report a model based on quantum-chemistry calculations and IR spectra simulation of neutral and charged endo(exo)hedral metallofullerenes, showing that they have a significant contribution to the four strongest IR bands commonly attributed to neutral C60. These simulations may explain the large range of 17.4um/18.9um band ratios observed in very different fullerene-rich circumstellar environments like those around planetary nebulae and chemically peculiar R Coronae Borealis stars. Our proposed model also reveals that the 17.4um/18.9um band ratio in the metallofullerenes simulated IR spectra mainly depends on the metal abundances, ionization level, and endo/exo concentration in the circumstellar envelopes. We conclude that metallofullerenes are potential emitters contributing to the observed IR spectra in fullerene-rich circumstellar envelopes. Our simulated IR spectra indicate also that the James Webb Space Telescope has the potential to confirm or refute the presence of metallofullerenes (or even other fullerene-based species) in circumstellar enviroments.

description: As gas giant planets evolve, they may scatter other planets far from their original orbits to produce hot Jupiters or rogue planets that are not gravitationally bound to any star. Here, we consider planets cast out to large orbital distances on eccentric, bound orbits through a gaseous disk. With simple numerical models, we show that super-Earths can interact with the gas through dynamical friction to settle in the remote outer regions of a planetary system. Outcomes depend on planet mass, the initial scattered orbit, and the evolution of the time-dependent disk. Efficient orbital damping by dynamical friction requires planets at least as massive as the Earth. More massive, longer-lived disks damp eccentricities more efficiently than less massive, short-lived ones. Transition disks with an expanding inner cavity can circularize orbits at larger distances than disks that experience a global (homologous) decay in surface density. Thus, orbits of remote planets may reveal the evolutionary history of their primordial gas disks. A remote planet with an orbital distance ~100 AU from the Sun is plausible and might explain correlations in the orbital parameters of several distant trans-Neptunian objects.

Designing inclusive mobility hubs for the 15-min-city

name: Martinez, Lluis
Publisher: name: Zenodo
Year: 2023

description: The ideal 15-minute city would also provide comfortable and accessible "interfaces" between different sustainable modes of transport such as public transport, shared mobility, walking and cycling. These interfaces, i.e. mobility hubs, physical locations where multiple modes of public and shared transport are available can facilitate multimodal trips but can also provide space for social interaction and commercial or service functions (e.g. coffee shop, bike repair shop, parcel lockers).
An inclusive design process can ensure that these hubs can provide benefits to all layers of society taking into account the needs of all potential users such as vulnerable people with low digital skills, physical or mental impairments or low income.
In this paper, we present a user-centric design approach for neighborhood-level mobility hubs that is based on the assessment of the needs of different vulnerable groups. We conducted 45 semi-structured interviews and four focus groups with local experts and potential users in Brussels, Munich, Rotterdam-The Hague and Vienna, to identify the needs and barriers encountered by vulnerable citizens.
Then, we adopted an inclusive co-design approach through on-street events, workshops with vulnerable people and a stakeholder-based appraisal to demonstrate the approach in Brussels. As a result, four alternative designs of a future mobility hub have been developed with citizens and other stakeholders.

description: Magnetic fields permeate the entire Galaxy and are essential to, for example, the regulation of several stages of the star formation process and cosmic ray transportation. Unraveling its properties, such as intensity and topology, is an observational challenge that requires combining different and complementary techniques. The polarization of starlight due to the absorption by field-aligned non-spherical dust grains provides a unique source of information about the interstellar magnetic field in the optical band. This work introduces a first analysis of a new catalog of optical observations of linearly polarized starlight in the diffuse interstellar medium (ISM), the Interstellar Polarization Survey, General ISM (IPS-GI). We used data from the IPS-GI, focusing on 38 fields sampling lines of sight in the diffuse medium. The fields are about 0.3$^{\circ}$ by 0.3$^{\circ}$ in size and each of them contains $\sim1000$ stars on average. The IPS-GI catalog has polarimetric measurements of over 40000 stars, over 18000 of which have ${P}/σ_{P} > 5$. We added distances and other parameters from auxiliary catalogs to over 36000 of these stars. We analyzed parameter distributions and correlations between parameters of a high-quality subsample of 10516 stars (i.e. $\sim275$ stars per field). As expected, the degree of polarization tends to increase with the extinction, producing higher values of polarization at greater distances or at lower absolute Galactic latitudes. Furthermore, we find evidence for a large-scale ordered Galactic magnetic field.

description: Requirement engineering is a key ingredient for software development to be effective. Apart from the traditional software requirement which is not much appropriate for new emerging software such as smart handheld device based software. In many perspectives of requirement engineering, traditional and new emerging software are not similar. Whereas requirement engineering of traditional software needs more research, it is obvious that new emerging software needs methodically and in-depth research for improved productivity, quality, risk management and validity. In particular, the result of this paper shows that how effective requirement engineering can improve in project negotiation, project planning, managing feature creep, testing, defect, rework and product quality. This paper also shows a new methodology which is focused on users work process applicable for eliciting the requirement of traditional software and any new type software of smart handheld device such as iPad. As an example, the paper shows how the methodology will be applied as a software requirement of iPad-based software for play-group students.

description: We use topology of configuration spaces to give a characterization of Neuwirth--Stallings pairs $(S^5, K)$ with $\dim K = 2$. As a consequence, we construct polynomial map germs $(\mathbb{R}^{6},0)\to (\mathbb{R}^{3},0)$ with an isolated singularity at the origin such that their Milnor fibers are not diffeomorphic to a disk, thus putting an end to Milnor's non-triviality question. Furthermore, for a polynomial map germ $(\mathbb{R}^{2n},0) \to (\mathbb{R}^{n},0)$ or $(\mathbb{R}^{2n+1},0) \to (\mathbb{R}^{n},0)$, $n \geq 3$, with an isolated singularity at the origin, we study the conditions under which the associated Milnor fiber has the homotopy type of a bouquet of spheres. We then construct, for every pair $(n, p)$ with $n/2 \geq p \geq 2$, a new example of a polynomial map germ $(\mathbb{R}^n,0) \to (\mathbb{R}^p,0)$ with an isolated singularity at the origin such that its Milnor fiber has the homotopy type of a bouquet of a positive number of spheres.

description: Protein subcellular localization is an important factor in normal cellular processes and disease. While many protein localization resources treat it as static, protein localization is dynamic and heavily influenced by biological context. Biological pathways are graphs that represent a specific biological context and can be inferred from large-scale data. We develop graph algorithms to predict the localization of all interactions in a biological pathway as an edge-labeling task. We compare a variety of models including graph neural networks, probabilistic graphical models, and discriminative classifiers for predicting localization annotations from curated pathway databases. We also perform a case study where we construct biological pathways and predict localizations of human fibroblasts undergoing viral infection. Pathway localization prediction is a promising approach for integrating publicly available localization data into the analysis of large-scale biological data.

description: The study proposes and tests a technique for automated emotion recognition through mouth detection via Convolutional Neural Networks (CNN), meant to be applied for supporting people with health disorders with communication skills issues (e.g. muscle wasting, stroke, autism, or, more simply, pain) in order to recognize emotions and generate real-time feedback, or data feeding supporting systems. The software system starts the computation identifying if a face is present on the acquired image, then it looks for the mouth location and extracts the corresponding features. Both tasks are carried out using Haar Feature-based Classifiers, which guarantee fast execution and promising performance. If our previous works focused on visual micro-expressions for personalized training on a single user, this strategy aims to train the system also on generalized faces data sets.
Superflares on the slowly rotating solar-type stars KIC10524994 and KIC07133671?

description: An investigation of the G-type stellar population with Kepler (as done by Maehara et al.) shows that less than 1 per cent of those stars show superflares. Due to the large pixel scale of Kepler ($\sim4 arcsec \: px^{-1}$), it is still not clear whether the detected superflares really occur on the G-type stars. Knowing the origin of such large brightenings is important to study their frequency statistics, which are uncertain due to the low number of sun-like stars ($T_{eff} = 5600-6000 \:K$ and $P_{rot} > 10 \:d$) which are currently considered to exhibit superflares. We present a complete Kepler data analysis of the sun-like stars KIC10524994 and KIC07133671 (the only two stars within this subsample of solar twins with flare energies larger than $10^{35}$ erg; Maehara et al.), regarding superflare properties and a study about their origin. We could detect four new superflares within the epoch Maehara et al. investigated and found 14 superflares in the remaining light curve for KIC10524994. Astrometric Kepler data of KIC07133671 show that the photocentre is shifted by 0.006 px or 25 mas during the one detected flare. Hence, the flare probably originated from another star directed towards the north-east. This lowers the superflare rate of sun-like stars (and hence the Sun) for $E > 10^{35}$ erg, since this additional star is probably not solar-like.

description: Transformer layers, which use an alternating pattern of multi-head attention and multi-layer perceptron (MLP) layers, provide an effective tool for a variety of machine learning problems. As the transformer layers use residual connections to avoid the problem of vanishing gradients, they can be viewed as the numerical integration of a differential equation. In this extended abstract, we build upon this connection and propose a modification of the internal architecture of a transformer layer. The proposed model places the multi-head attention sublayer and the MLP sublayer parallel to each other. Our experiments show that this simple modification improves the performance of transformer networks in multiple tasks. Moreover, for the image classification task, we show that using neural ODE solvers with a sophisticated integration scheme further improves performance.

Pain threshold
Autoalgometry

description: Nowadays, researchers and clinicians are increasingly interested in alternative nonpharmacological treatments, and music therapy seems to have additional and powerful effects on different pathologies and pain. However, since pain is a subjective perception, it is difficult to evaluate if and which effect music has on it. In this study, a new device and method have been introduced to objectively estimate pain threshold and its changes related to external stimuli. The abovementioned device, called autoalgometer, allows to evaluate pain threshold changes while listening to music or other sounds. In this experiment, the pain threshold was evaluated in twenty-seven volunteers after listening to one out of three different soundtracks: white noise, Mozart’s sonata K448 or Brian Eno’s ambient music. Compared to staying in silence, listening to the recordings had no significant effect on pain threshold, and the results did not show any significant difference between the experimental groups. Probably, the positive effect of music described in other studies can be ascribed to a psychological effect, meaning that music can improve subjective mood and, thus, modify pain perception.

description: Bcl-2-associated athanogene 3 (BAG3) belongs to the family of co-chaperone proteins that interact with the heat shock protein 70 (Hsp70) and is involved in a number of cellular processes including proliferation and apoptosis. BAG3 contains the BAG domain which interacts with the ATPase domain of Hsp70. BAG3 is also characterized by the presence of a WW domain, two conserved Ile-Pro-Val (IPV) motifs and a proline-rich (PXXP) repeat that mediate the binding to partners different from Hsp70. These diverse and multiple interactions underlie the ability of BAG3 to modulate major biological processes such as development, cytoskeleton organization and autophagy. In our laboratory, BAG3 has been recently found in a soluble or membrane-associated form and it has been detected in the serum obtained from patients with pancreatic cancer or heart failure. Moreover, we found that BAG3 is able to bind the cell surface of macrophages and activate the production of inflammatory associated components, such as Nitric Oxide (NO) and Interleukin (IL) -6. To identify novel interacting partners of BAG3 an affinity chromatography on nickel-charged resin was performed, in J774A.1 cells, using recombinant BAG3 (rBAG3) followed by mass spectrometry analysis of the rBAG3-containing complexes. Among these, Interferon- Inducible TransMembrane (IFITM) -2 and Neuropilin (NRP) -1 were the only transmembrane proteins and therefore represented good candidates as receptors for BAG3. Our results show that NRP-1 and IFITM-2 are both essential for the binding of rBAG3 to the cell surface of macrophages and its activation for IL-6 release. We then investigated if BAG3 binding activates some of the signaling pathways known to be involved in macrophage activation. In particular we focused on the phosphatidylinositol 3-kinase (PI3K) and on the p38 pathway that are both involved in Cox-2, iNOS and IL-6 induction in macrophages. We demonstrated that BAG3 signaling is mediated by the receptor complex we identified, since IFITM-2 and/or NRP-1 silencing abrogates BAG3- induced phosphorylation of AKT and p38. We than focus our study on human monocytes, rBAG3 binds the cell surface and induces the release of many pro-inflammatory cytokines and chemokines. Furthermore, we have shown that rBAG3 can bind T lymphocytes cells surface after lipopolysaccharide (LPS) stimulus. All together these findings suggest a role for extracellular BAG3 in immune response. [edited by Author]

description: In this study, we present high-resolution millimeter observations of the dust and gas disk of the T Tauri star AS 205 N and its companion, AS 205 S, obtained with the Atacama Large Millimeter Array. The gas disk around AS 205 N, for which infrared emission spectroscopy demonstrates significant deviations from Keplerian motion that has been interpreted as evidence for a disk wind (Pontoppidan et al. 2011; Bast et al. 2011), also displays significant deviations from Keplerian disk emission in the observations presented here. Detections near both AS 205 N and S are obtained in 1.3 mm continuum, 12CO 2-1, 13CO 2-1 and C18O 2-1. The 12CO emission is extended up to 2 arcsec from AS 205N, and both 12CO and 13CO display deviations from Keplerian rotation at all angular scales. Two possible explanations for these observations hold up best to close scrutiny - tidal interaction with AS 205 S or disk winds (or a combination of the two), and we discuss these possibilities in some detail.

description: A thin infinitely long elastic shell is stiffened by $J$ in number identical lengthwise ribs distributed uniformly around the circumference and joined to a rod in the center. The 2D model of the substructure is a rigid central mass supported by $J$ axisymmetrically placed linear springs. The response of the shell-spring-mass system is quite different from a fluid filled shell or that of a solid cylinder due to the discrete number of contact points which couple the displacement of the shell at different locations. Exterior acoustic scattering due to normal plane wave incidence is solved in closed form for arbitrary $J$. The scattering matrix associated with the normal mode solution displays a simple structure, composed of distinct sub-matrices which decouple the incident and scattered fields into $J$ families. The presence of a springs-mass substructure causes resonances which are shown to be related to the subsonic shell flexural waves, and an approximate analytic expression is derived for the quasi-flexural resonance frequencies. Numerical simulations indicate that the new solution for $J\ge 3$ springs results in a complicated scattering response for plane wave incidence. As the number of springs becomes large enough, the total scattering cross-section is asymptotically zero at low frequencies and slightly increased compared to the empty shell at moderate frequencies due to the added stiffness and mass. It is also observed that the sensitivity to the angle of incidence diminishes as the number of springs is increased. This system can be tuned by selecting the shell thickness, spring stiffness and added mass to yield desired quasi-static effective properties making it a candidate element for graded index sonic crystals.

description: Hardly any real self-propelling or actively driven object is perfect. Thus, undisturbed motion will generally not follow straight lines but rather circular trajectories. We here address self-propelled or actively driven objects that move in discrete steps and additionally tempt to migrate towards a certain direction by discrete angular adjustment. Overreaction in the angular alignment is possible. This competition implies pronounced nonlinear dynamics including period doubling and chaotic behavior in a broad parameter regime. Such behavior directly affects the appearance of the trajectories, also during collective motion under spatial self-concentration.

description: The surface of a crystal made of roughly spherical molecules exposes, above its bulk rotational phase transition at T= T$_r$, a carpet of freely rotating molecules, possibly functioning as "nanobearings" in sliding friction. We explored by extensive molecular dynamics simulations the frictional and adhesion changes experienced by a sliding C$_{60}$ flake on the surface of the prototype system C$_{60}$ fullerite. At fixed flake orientation both quantities exhibit only a modest frictional drop of order 20% across the transition. However, adhesion and friction drop by a factor of $\sim$ 2 as the flake breaks its perfect angular alignment with the C$_{60}$ surface lattice suggesting an entropy-driven aligned-misaligned switch during pull-off at T$_r$. The results can be of relevance for sliding Kr islands, where very little frictional differences were observed at T$_r$, but also to the sliding of C$_{60}$ -coated tip, where a remarkable factor $\sim$ 2 drop has been reported.

description: Η παρούσα μελέτη έγινε με σκοπό να εξετάσει τα εμβιομηχανικά χαρακτηριστικά της μετάβασης από την καθιστή στην όρθια στάση (STS), μετά από μυϊκή βλάβη και καθυστερημένο μυϊκό πόνο (DOMS). Το δείγμα της έρευνας αποτέλεσαν δεκαπέντε υγιής ενήλικες γυναίκες ηλικίας 23 ± 2,83 έτη. Ανάλυση της κίνησης έγινε πριν και 48 ώρες μετά από πρωτόκολλο μυϊκής βλάβης. Κατά την διάρκεια του πειράματος ζητήθηκε από τα άτομα να εκτελέσουν πέντε προσπάθειες, της κίνησης, σε καρέκλα που το ύψος της είχε ορισθεί στα 43cm. Για την συλλογή των κινηματικών και κινητικών δεδομένων χρησιμοποιήθηκε ένα οπτικοηλεκτρονικό σύστημα ανάλυσης κίνησης (VICON) με δέκα κάμερες και μία πλατφόρμα καταγραφής δυνάμεων αντίδρασης εδάφους (BERTEC). Σημαντικές διαφορές παρατηρήθηκαν στις δυνάμεις αντίδρασης εδάφους. Οι κινηματικές παράμετροι τις λεκάνης και των αρθρώσεων του γόνατος και του ισχίου παρουσίασαν μεταβολές στατιστικά σημαντικές. Η διάρκεια της κίνησης αυξήθηκε και μειώθηκε σημαντικά η γωνιακή ταχύτητα των αρθρώσεων του γόνατος και του ισχίου. Οι ροπή μειώθηκε σημαντικά στην φάση έκτασης της κίνησης στις αρθρώσεις του ισχίου και του γόνατος, όπως και η ισχύς τους. Συμπερασματικά, η μυϊκή βλάβη και ο καθυστερημένος μυϊκός πόνος, άλλαξαν την μηχανική της κίνησης. Οι μεταβολές αυτές της κίνησης, παρουσιάζουν ομοιότητες με την στρατηγική που χρησιμοποιούν άνθρωποι τρίτης ηλικίας και άλλες ευπαθείς πληθυσμιακές ομάδες, κάτι που πιθανά να βοηθήσει στο σχεδίασμά προγραμμάτων αποκατάστασης.

description: We have developed a pipeline called \mentari to generate the far-ultraviolet to far-infrared spectral energy distribution (SED) of galaxies from the \dustysage semi-analytic galaxy formation model (SAM). \dustysage incorporates dust-related processes directly on top of the basic ingredients of galaxy formation like gas infall, cooling, star formation, feedback, and mergers. We derive a physically motivated attenuation model from the computed dust properties in \dustysage, so each galaxy has a self-consistent set of attenuation parameters based on the complicated dust physics that occurred across the galaxy's assembly history. Then, we explore several dust emission templates to produce infrared spectra. Our results show that a physically-motivated attenuation model is better for obtaining a consistent multi-wavelength description of galaxy formation and evolution, compared to using a constant attenuation. We compare our predictions with a compilation of observations and find that the fiducial model is in reasonable agreement with: (i) the observed $z=0$ luminosity functions from the far-ultraviolet to far-infrared simultaneously, and hence (ii) the local cosmic SED in the same range, (iii) the rest-frame K-band luminosity function across $0 < z < 3$, and (iv) the rest-frame far-ultraviolet luminosity function across $0 < z < 1$. Our model underproduces the far-ultraviolet emission at $z=2$ and $z=3$, which can be improved by altering the AGN feedback and dust processes in \dustysage. However, this combination thus worses the agreement at $z=0$, which suggests that more detailed treatment of such processes is required.

description: In the context of modified tele-parallel theory of gravity, we undertake cosmological anisotropic models and search for their solutions. Within a suitable choice of non-diagonal tetrads, the decoupled equations of motion are obtained for Bianchi-I, Bianchi-III and Kantowski-Sachs models, from which we obtain the correspondent solutions. By the way, energy density and pressures are also obtained, showing, as an important result, that our universe may live a quintessence like universe even still anisotropic models are considered.

description: This article analyzes, with a qualitative methodology, the problems underlying the delicate correlation between representation, participation, conflict, assessed in the context of the radical democracy studies and in consideration of the Latin American scenario, the laboratory par excellence of participatory practices, involved during the course of the last year by interesting protests and demonstrations. The outbreak of social conflict in this region has underlined the crisis and dysfunctionality of the democratic circuit, highlighting however interesting news compared to the past, both in terms of the peculiarity of the protest and its channeling for the purpose of redefining the political-institutional space, as well as incidence of digital ecosystems for the organization and maintenance of the action.

description: Discourse parsing is an essential upstream task in Natural Language Processing with strong implications for many real-world applications. Despite its widely recognized role, most recent discourse parsers (and consequently downstream tasks) still rely on small-scale human-annotated discourse treebanks, trying to infer general-purpose discourse structures from very limited data in a few narrow domains. To overcome this dire situation and allow discourse parsers to be trained on larger, more diverse and domain-independent datasets, we propose a framework to generate "silver-standard" discourse trees from distant supervision on the auxiliary task of sentiment analysis.

description: The International System of Units (SI) is supposed to be coherent. That is, when a combination of units is replaced by an equivalent unit, there is no additional numerical factor. Here we consider dimensionless units as defined in the SI, {\it e.g.} angular units like radians or steradians and counting units like radioactive decays or molecules. We show that an incoherence may arise when different units of this type are replaced by a single dimensionless unit, the unit "one", and suggest how to properly include such units into the SI in order to remove the incoherence. In particular, we argue that the radian is the appropriate coherent unit for angles and that hertz is not a coherent unit in the SI. We also discuss how including angular and counting units affects the fundamental constants.
