description: The current document, titled ’Second version of TIME4CS Clustering activities and user engagement activities report’, has been developed within the framework of the TIME4CS project which is funded by the European Union’s Horizon 2020 Research and Innovation Programme under Grant Agreement No 101006201. The purpose of this Deliverable is to present an overview of the communication and dissemination activities completed by the TIME4CS consortium in the first 24 months of the project, in order to generate enhanced collaborations with other relevant international organisations and projects on the topic of Science with and for Society and/or citizen science (hereinafter referred to as “sister projects”). This report gives an overview of what clustering represents for TIME4CS and details what the project can offer from this perspective. The engagement strategy is also discussed and details are presented for each initially proposed collaboration. The document then presents an overview of the TIME4CS Case studies and the Citizen Science Helix. This report also discusses future plans that the consortium has in place in order to continue cross-collaboration activities.

description: We have carried out near-infrared (NIR) imaging observations of the Carina Nebula for an area of ~400 sq. arcmin. including the star clusters Trumpler 14 (Tr 14) and Trumpler 16 (Tr 16). With 10 sigma limiting magnitudes of J ~ 18.5, H ~ 17.5 and K_s ~ 16.5, we identified 544 Class II and 11 Class I young star candidates. We find some 40 previously unknown very red sources with H-K_s > 2, most of which remain undetected at the J band. The red NIR sources are found to be concentrated to the south-east of Tr 16, along the `V' shaped dust lane, where the next generation of stars seems to be forming. In addition, we find indications of ongoing star formation near the three MSX point sources, G287.51-0.49, G287.47-0.54, and G287.63-0.72. A handful of red NIR sources are seen to populate around each of these MSX sources. Apart from this, we identified two hard Chandra X-ray sources near G287.47-0.54, one of which does not have an NIR counterpart and may be associated with a Class I/Class 0 object. The majority of the Class II candidates, on the other hand, are seen to be distributed in the directions of the clusters, demarcating different evolutionary stages in this massive star-forming region. A comparison of the color-magnitude diagrams of the clusters with pre-main sequence model tracks shows that the stellar population of these clusters is very young (< 3 Myr). The K_s band luminosity function (KLF) of Tr 14 shows structure at the faint end, including a sharp peak due to the onset of deuterium burning, implying an age of 1-2 Myr for the cluster. The KLF of Tr 16, in contrast, is found to rise smoothly until it turns over. The slopes of the mass functions derived for the clusters are found to be in agreement with the canonical value of the field star initial mass function derived by Salpeter.

description: The languages of Russia are a valuable resource of knowledge about the life of the indigenous peoples and a challenge for all the specialists in linguistic typology. As is widely known, they are undergoing the process of loss, mainly because the quantity of speakers diminishes and the quality of their speech deteriorates. The article discusses the situation of Udmurt and Chuvash in education on the basis of legal texts, statistical data, interviews to parents, teachers and school officials and schoolchildren pooling. Although Udmurt and Chuvash are being taught as a subject in many schools where the language of instruction is Russian, the results are not satisfying. This problem, being psychological in its nature, lies in attitudes prevalent in society and in the schools. The minority languages are practiced in a small number of situations, and a small number of students really care about elaboration of their own ways of belonging, because they experience that the native language is not prestigious. At the same time, to use some words and to know some traditions is respectful, especially when someone visits abroad and is welcomed much better as a representative of a minority than as a Russian. Although bilingualism among the citizens of Russia is quite common, it was studied poorly. A ‘new generation’ of didactic materials is needed.

Subjects: Disciplinarity; interdisciplinarity; social construction; social sciences; unification; forms of knowledge; civic education; economic education

description: Social Science Education as a subject field in schools is an intrinsic pluridisciplinary feature, whatever disciplines are included, however it may be organised and wherever it may be institutionalised. Civic education, economic education, social education and historical education each comprise several academic disciplines even if they are thought to be completely independent subjects. From the start on, disciplinarity and interdisciplinarity are on the agenda for any subject related to social science education and are one of its main problems. For these introductory remarks interdisciplinarity can be simply defined as relating two or more academic disciplines or school subjects to each other if this is done in a purposeful, systematic, explicit and reflective way. The overarching goal is to improve education that is to enhance students' understandings of the worlds and their abilities to act within and towards them. A relationship between disciplines or subjects which misses one or more of the four characteristics can be called pluridisciplinary or multidisciplinary (cf. Audigier 2006). In the following I first want to discuss some aspects of disciplinarity and interdisciplinarity at schools and at universities and the weakness of interdisciplinarity. I sketch some social science based ideas on the interrelationship between the subject structure of the academic world and the world of schools (3.) and of some tendency to commonalities or even unification of social sciences and related competencies (4.). I conclude with some remarks on different kinds of knowledge (5.). Last but not least, I'll give an overview on the papers in this issue of the Journal of Social Science Education (6.).

description: Makienko's conjecture, a proposed addition to Sullivan's dictionary, can be stated as follows: The Julia set of a rational function R has buried points if and only if no component of the Fatou set is completely invariant under the second iterate of R. We prove Makienko's conjecture for rational functions with Julia sets that are decomposable continua. This is a very broad collection of Julia sets; it is not known if there exists a rational functions whose Julia set is an indecomposable continuum.

Spectral properties of quasi-one-dimensional conductors with a finite transverse band dispersion

description: We determine the one-particle spectral function and the corresponding derived quantities for the conducting chain lattice with the finite inter-chain hopping $t_\perp$ and the three-dimensional long-range Coulomb electron-electron interaction. The standard $G_{0}W_{0}$ approximation is used. It is shown that, due to the optical character of the anisotropic plasmon dispersion caused by the finite $t_\perp$, the low energy quasi-particle $δ$-peak appears in the spectral function in addition to the hump present at the energies of the order of plasmon energy. The particular attention is devoted to the continuous cross-over from the non-Fermi liquid to the Fermi liquid regime by increasing $t_\perp$. It is shown that the spectral weight of the hump transfers to the quasi-particle as the optical gap in the plasmon dispersion increases together with $t_\perp$, with the quasi-particle residuum $Z$ behaving like $- (\ln t_{\perp})^{-1}$ in the limit $t_{\perp}\to 0$. Our approach is appropriate for the wide range of energy scales given by the plasmon energy and the width of the conduction band, and is complementary to the Luttinger liquid techniques that are limited to the low energy regime close to the Fermi surface.

description: We use a scanning tunneling microscope operating in a low temperature, ultrahigh vacuum environment to study the atomic structure of single layer films of Cu2N grown on Cu(100). The c(2x2) lattice of Cu2N is incommensurate, with a lattice constant of 3.72 +/- 0.02 angstrom that is 3% larger than the bare Cu(100) surface. This finding suggests that strain due to lattice mismatch contributes to self assembly in this system. We find that the image contrast on Cu2N islands depends on bias voltage, which reconciles several interpretations in the literature. We assign features in these STM images to the Cu, N and hollow sites in the Cu2N lattice with the aid of co-adsorbed CO molecules. This atomic registry allows us to characterize four different defects on Cu2N, which influence the sticking coefficient and electronic coupling of adsorbates.

Collisionless relaxation in gravitational systems: From violent relaxation to gravothermal collapse

description: Theory and simulations are used to study collisionless relaxation of a gravitational $N$-body system. It is shown that when the initial one particle distribution function satisfies the virial condition -- potential energy is minus twice the kinetic energy -- the system quickly relaxes to a metastable state described {\it quantitatively} by the Lynden-Bell distribution with a cutoff. If the initial distribution function does not meet the virial requirement, the system undergoes violent oscillations, resulting in a partial evaporation of mass. The leftover particles phase separate into a core-halo structure. The theory presented allows us to quantitatively predict the amount and the distribution of mass left in the central core, without any adjustable parameters. On a longer time scale $τ_G \sim N$ collisionless relaxation leads to a gravothermal collapse.
Spontaneous Symmetry Breaking and Decoherence in Superconductors

description: We show that superconductors have a thin spectrum associated with spontaneous symmetry breaking similar to that of antiferromagnets, while still being in full agreement with Elitzur's theorem, which forbids the spontaneous breaking of local (gauge) symmetries. This thin spectrum in the superconductors consists of in-gap states that are associated with the spontaneous breaking of a global phase symmetry. In qubits based on mesoscopic superconducting devices, the presence of the thin spectrum implies a maximum coherence time which is proportional to the number of Cooper pairs in the device. Here we present the detailed calculations leading up to these results and discuss the relation between spontaneous symmetry breaking in superconductors and the Meissner effect, the Anderson-Higgs mechanism and the Josephson effect. Whereas for the Meissner effect a symmetry breaking of the phase of the superconductor is not required, it is essential for the Josephson effect.

The use of genetic algorithm to model protoplanetary discs

description: The protoplanetary discs of T Tauri and Herbig Ae/Be stars have been studied by using geometric disc models to fit their spectral energy distribution (SED). The simulations provide means to reproduce the signatures of different circumstellar structures, which are related to different levels of infrared excess. Aiming to improve our previous model that assumed a simple flat disc configuration, in the present work we adopt a reprocessing flared disc model that considers hydrostatic, radiative equilibrium (Dullemond et al. 2001). We developed a method to optimise the parameters estimation based on genetic algorithms (GA). This paper is dedicated to describe the implementation of the new code, which has been applied for Herbig stars from the Pico dos Dias Survey catalogue, in order to illustrate the quality of the fitting for a variety of SED shapes. The star AB Aur was used as a test of the GA parameters estimation, demonstrating that the new code reproduces successfully a canonical example of the flared disc model. The GA method gives good quality of fittings, but the range of input parameters must be chosen with caution, since unrealistic disc parameters can be derived. The flared disc model is confirmed to fit the flattened SEDs typical from Herbig stars, however the embedded objects (increasing SED slope) and debris discs (steeper SED) are not well fitted with this configuration. Even considering the limitation of the derived parameters, the automatic process of SED fitting provides an interesting tool for the statistical analysis of the circumstellar luminosity of large samples of young stars.

description: It is recently announced by the {\bf Ut}{\it fit} collaboration that the CP phase of the $B_s$ mixing amplitude, $ϕ_{B_s}$, deviates more than $3 σ$ from the standard-model prediction. In this paper we discuss how large correction to $ϕ_{B_s}$ is possible in the supersymmetric SU(5) ground unified model (SUSY SU(5) GUT) with right-handed neutrinos. Here, we assume the supergravity-like boundary condition for the SUSY-breaking terms. We found that the 95% probability region derived by the {\bf Ut}{\it fit} collaboration is marginal in this model.

description: Temporal and energy characteristics of the very-high-energy gamma-ray bursts from evaporating primordial black holes have been calculated by assuming that the photospheric and chromospheric effects are negligible. The technique of searching for such bursts on shower arrays is described. We show that the burst time profile and the array dead time should be taken into account to interpret experimental data. Based on data from the Andyrchy array of the Baksan Neutrino Observatory (Institute for Nuclear Research, Russian Academy of Sciences), we have obtained an upper limit on the number density of evaporating primordial black holes in a local region of space with a scale size of ~10^{-3} pc. Comparison with the results of previous experiments is made.

description: This deliverable presents the final release of workflows and modular tools designed and developed in the BioExcel project during the last three years. A summary of the software development process adopted, following a set of best practices promoted by ELIXIR, is exposed together with examples of working implementations. Availability of the building blocks and workflows produced so far by the project is listed, describing where to find them and how can they be installed and used, presenting a variety of approaches designed for different types of users.

The current stage of the Model Protein Mutants transversal workflow, used as a pivot study and demonstrator for the workflows software library development, is revised. Also, two scientific success stories achieved using this pipeline are presented, showing the potential of the methodology in a real scenario. The current implementation for each of the project pilot use cases is detailed, with special focus on the workflows behind them, availability and feedback.

Finally, the services provided and the present phase for the two deployment environments, development and production, is outlined. An overview of the tools developed and those currently available in each of the cloud and HPC infrastructures is given. Particularly successful use cases produced by the BSC testbed and the BioExcel Cloud Portal are depicted.
A Novel phase in the phase structure of the $(gϕ^4 + hϕ^6)_{1+1}$ field theoretic model

description: In view of the newly discovered and physically acceptable $PT$ symmetric and non-Hermitian models, we reinvestigated the phase structure of the ($gϕ^{4}+hϕ^{6}$)$_{1+1}$ Hermitian model. The reinvestigation concerns the possibility of a phase transition from the original Hermitian and $PT$ symmetric phase to a non-Hermitian and $PT$ symmetric one. This kind of phase transition, if verified experimentally, will lead to the first proof that non-Hermitian and $PT$ symmetric models are not just a mathematical research framework but are a nature desire. To do the investigation, we calculated the effective potential up to second order in the couplings and found a Hermitian to Non-Hermitian phase transition. This leads us to introduce, for the first time, hermiticity as a symmetry which can be broken due to quantum corrections, \textit{i.e.}, when starting with a model which is Hermitian in the classical level, quantum corrections can break hermiticity while the theory stays physically acceptable. In fact, ignoring this phase will lead to violation of universality when comparing this model predictions with other models in the same class of universality. For instance, in a previous work we obtained a second order phase transition for the $PT$ symmetric and non-Hermitian $(-gϕ^{4})$ and according to universality, this phase should exist in the phase structure of the ($gϕ^{4}+hϕ^{6}$) model for negative $g$. Finally, among the novelties in this letter, in our calculation for the effective potential, we introduced a new renormalization group equation which describes the invariance of the bare vacuum energy under the change of the scale. We showed that without this invariance, the original theory and the effective one are inequivalent.

description: Anomalous nematic states, recently discovered in ultraclean two-dimensional electron gas, emerge from quantum Hall stripe phases upon further cooling. These states are hallmarked by a local minimum (maximum) in the hard (easy) longitudinal resistance and by an incipient plateau in the Hall resistance in nearly half-filled Landau levels. Here, we demonstrate that a modest in-plane magnetic field, applied either along $\left < 110 \right >$ or $\left < 1\bar10 \right >$ crystal axis of GaAs, destroys anomalous nematic states and restores quantum Hall stripe phases aligned along their native $\left < 110 \right >$ direction. These findings confirm that anomalous nematic states are distinct from other ground states and will assist future theories to identify their origin.

Defensive strategies of schooling prey under predatory stress
Creators: name: Palermo, R. V.
Publisher: name: University of British Columbia
Year: 2010

description: The strategy and tactics of avoiding a predator by a schooling prey are examined using the specific example of rainbow trout ( Salmo qairdneri ) chasing single and schooling sockeye salmon ( Oncorhyncus nerka ). Three general rules of defensive strategy are developed from the examination of predation as a process and from parallels in modern aerial warfare. The first rule is based on prey vigilance. Rule 1. The best strategy from the prey point of view is not to be detected by a predator, and to detect the presence of a predator as soon as possible, preferably before detection. It is best to avoid a chase, which can be achieved by hiding, or moving away, so as to increase the distance from the predator. The second rule is based on group cohesion. Rule 2. Individuals and strays from groups are more vulnerable to predators, and school size and structure is limited by signal loss between individuals, therefore, the group should become more compact in spacing when attacked by predators. This will allow the execution of group manoeuvres with minimal group disintegration. The third rule is based on tactical manoeuvre considerations. Rule 3. The best manoeuvre that the group can perform, if it detects the predator at a distance that enables the manoeuvre to be executed, is to turn toward the direction of the predator. This enables the individuals to move around the predator when it engages the group. This results in positioning the predator behind and heading away from the group. The predator was found to use path prediction as an interception strategy and prey used rapid turning manoeuvres as a defensive strategy. The first response of schooling prey was to move away from the path direction of the predator while forming a more compact school. The second response of the school was to turn toward the path of the predator. The third response was rapid school disintegration as each individual turned rapidly and accelerated to a high linear velocity and oscillating angular velocity. Schooling by prey confuses and limits the ability of the predator to path predict. Consequently, predator capture success is greater when chasing single prey.

The phylogenetic affiliations of the type species of Cephennium, C. thoracicum, have not been thoroughly revised. Since the morphology of the aedeagus differs in many ways from that of the C. perispinctum group, this species is tentatively assigned to a group of its own. Only a single male is reported from North Spain, close to the border with France.

description: Laser cladding multi-channel forming is a complex, nonlinear process characterized by multi-parameter coupling. To determine the technology parameters, an optimization method of multivariate black-box prediction model (MVBM) matching non-dominated sequential genetic algorithm (NSGA-II) was constructed. Multi-channel LC orthogonal experiments were designed. The MVBM was established with process technology parameters as inputs and characteristic parameters reflecting the quality (surface hardness, dilution rate) as responses. The set of optimal solutions for technology parameters by the NSGA-II. The experimental results showed that, under the optimum parameters, the average hardness of the optimized increased by 6.1%, and the dilution rate was reduced by 49.8%. The dilution rate was maintained within the optimal range. The study’s findings can provide theoretical support for optimizing LC multi-objective technology parameters and improving coating quality control.

description: We use a new quenching scheme to study the dynamics of a one-dimensional anisotropic $XY$ spin-1/2 chain in the presence of a transverse field which alternates between the values $h+\de$ and $h-\de$ from site to site. In this quenching scheme, the parameter denoting the anisotropy of interaction ($\ga$) is linearly quenched from $-\infty$ to $ +\infty$ as $\ga = t/τ$, keeping the total strength of interaction $J$ fixed. The system traverses through a gapless phase when $\ga$ is quenched along the critical surface $h^2 = \de^2 + J^2$ in the parameter space spanned by $h$, $\de$ and $\ga$. By mapping to an equivalent two-level Landau-Zener problem, we show that the defect density in the final state scales as $1/τ^{1/3}$, a behavior that has not been observed in previous studies of quenching through a gapless phase. We also generalize the model incorporating additional alternations in the anisotropy or in the strength of the interaction, and derive an identical result under a similar quenching. Based on the above results, we propose a general scaling of the defect density with the quenching rate $τ$ for quenching along a gapless critical line.

description: In grand unified theories (GUT), non-universal boundary conditions for the gaugino masses may arise at the unification scale, and affect the observability of the neutral MSSM Higgs bosons (h/H/A) at the LHC. The implications of such non-universal gaugino masses are investigated for the Higgs boson production in the SUSY cascade decay chain gluino --> squark quark, squark --> neutralino_2 quark, neutralino_2 --> neutralino_1 h/H/A, h/H/A --> b b-bar produced in pp interactions. In the singlet representation with universal gaugino masses only the light Higgs boson can be produced in this cascade with the parameter region of interest for us, while with non-universal gaugino masses heavy neutral MSSM Higgs boson production may dominate. The allowed parameter space in the light of the WMAP constraints on the cold dark matter relic density is investigated in the above scenarios for gaugino mass parameters. We also demonstrate that combination of representations can give the required amount of dark matter in any point of the parameter space. In the non-universal case we show that heavy Higgs bosons can be detected in the studied cascade in parameter regions with the WMAP preferred neutralino relic density.

description: We discuss dynamical friction in an $N$-body system in the presence of tidal interactions caused by a distant external source. Using the distant tide approximation, we develop a perturbation scheme for the calculation of dynamical friction that takes tidal effects into account to linear order. In this initial analytic approach to the problem, we neglect the influence of tides on the distribution function of stars in the background stellar system. Our result for the dynamical friction force in the appropriate limit is in agreement with Chandrasekhar's formula in the absence of tides. We provide preliminary estimates for the tidal contributions to the dynamical friction force. The astrophysical implications of our results are briefly discussed.

description: We present an efficient architecture for quantum repeaters based on single-photon sources in combination with quantum memories for photons. Errors inherent to previous repeater protocols using photon-pair sources are eliminated, leading to a significant gain in efficiency. We establish the requirements on the single-photon sources and on the photon detectors.

description: El Lago Villarrica, uno de los lagos más emblemáticos del sur de Chile, ha sufrido durante décadas contaminación por diversas actividades humanas. A pesar de diversos esfuerzos públicos y privados para reducir las externalidades negativas durante años, no se pudo revertir el deterioro en la calidad de agua. Se presenta como un caso donde hay numerosos actores productivos cuyas actividades afectan a las aguas que llegan finalmente al lago, como son las pisciculturas, planta de tratamiento de aguas servidas y actividades asociadas con el turismo como las termas; además, hay varios sectores en la cuenca sin infraestructura sanitaria, generando un aporte difuso de contaminantes (MMA-UFRO 2019).el presente artículo propone y aplica una metodología para analizar el proceso de gobernanza colaborativa realizado para elaborar el Plan de Descontaminación del Lago Villarrica. En la primera parte, se establecen los criterios centrales que deben considerar un proceso de gobernanza colaborativa que facilitará la gestión de dicho Plan para su duración de 15 años. Después de presentar la metodología propuesta, se analiza el diseño del proceso y el funcionamiento de los dos comités establecidos para visibilizar la co-construcción de una comprensión compartida de las causas del problema y su solución. Se concluye con recomendaciones para mejorar el diseño y funcionamiento.

description: Following a solution generating technique introduced recently by one of us, we transform the Einstein static Universe into a two - fold infinity class of physically acceptable exact perfect fluid solutions of Einstein's equations. Whereas the entire class of solutions can be considered as generalizations of the familiar Tolman IV solution, no member of the class can be written explicitly in isotropic coordinates. Further, except for a set of measure zero, no member of the class can be written explicitly in curvature coordinates either.

description: This work controlled the polymerization reaction, melting, and mixing processing of a mixture including epoxy resin and polyethylene glycol (PEG) by a pulverizer, to effectively develop high-performance shape memory epoxy/PEG (EPP) filaments. The process parameters of polymerization-melting-mixing-drawing were determined through the extrusion force investigation. The results showed that EPP mixtures could be developed into filaments through polymerization-melting-mixing-drawing process, reducing the spinning temperature and filament diameter from 300°C and 31 mm to 235°C and 13 mm, respectively. The Fourier transform infrared spectra confirmed the complete polymerization of epoxy resin and the stable existence of PEG. EPP filaments developed through the polymerization-melting-mixing-drawing process have exhibited controllable dynamic thermal mechanical properties and Tg, excellent shape recovery effects, and adjustable stimulus temperature. This work developed shape memory EPP filaments through a polymerization-melting-mixing-drawing process, with controllable spinnability and adjustable stimulus temperature, providing a reference for high-performance filament fabrication and process optimization.

description: Wide field-of-view (FOV) sensors such as Sentinel-2 exhibit per-pixel view and illumination geometry variation that may influence the retrieval accuracy of essential crop biophysical and biochemical variables (BVs) for precision agriculture. However, this aspect is rarely studied in the existing literature. Hence, the current study aimed to evaluate the contribution of view and illumination geometries to the accuracy of retrieving Leaf Chlorophyll a and b (LCab), Canopy Chlorophyll Content (CCC), and Leaf Area Index (LAI) using the Random Forest (RF). The experiments were performed on various input variable scenarios where per-pixel geometric covariates, i.e. View and Sun Zenith Angles (VZA and SZA, respectively), and Relative Azimuth Angle (RAA), are excluded and included in spectral bands (SB) and spectral vegetation indices (SVIs), respectively, in two semi-arid areas. The results showed that spectral bands or vegetation indices combined with geometric covariates improved the R2 by 10–15% for LAI and 3–5% for CCC. In contrast, negligible improvements of 1–2% were achieved for LCab with cross-validation test data and independent held-out dataset, respectively. In agreement with previous studies, VZA and SZA were among the topmost influential variables in the RF models for estimating LAI, LCab, and CCC. Collectively, per-pixel geometric variables explained more than 30% of the variability in surface reflectance for all Sentinel-2 spectral bands (p < 2.2e-16). Overall, the results showed that incorporating geometric covariates improved the accuracy of retrieving BVs; thus, it provided additional information that improves the predictive power of SB and SVIs. The significant benefits of the geometric variables were mainly realized for canopy-level BVs (i.e. LAI and CCC) than for LCab. Therefore, it is recommended to incorporate per-pixel view and illumination geometry in estimating LAI and CCC, especially when using wide-view sensors such as Sentinel-2. However, further testing in different phenology, site and acquisition conditions is needed to confirm the contribution of the geometric covariates to facilitate reliable retrieval of BVs from remotely sensed data and aid better agronomic decisions.
