description: Convective clouds are associated with extreme precipitation events triggering floods. They are an important part of atmospheric circulation and hydrological cycle. Changes in convective clouds in changing climate remain one of the most challenging aspects of forecasting future climate change. The present research focuses on identification of convective clouds using multispectral measurements at split window channels (near 10.5 µm and 12.5 µm) and water vapour absorption channels (near 6.7 µm) from Meteosat 7 observations. Variability of convective clouds has been examined in warming climate using observations from Meteosat First Generation (MFG). It has been reported that convective clouds show high density over Western, Central, North Eastern Indian region, and the Western Ghats during the monsoon period. This observation is consistent with measurement from Precipitation Radar (PR) (reflectivity-based threshold) on-board Tropical Rainfall Measuring Mission (TRMM) and rain gauge-based product. The present technique fails to detect shallow convective clouds over the Western Ghats. An increase of about 32.68% ± 5.81% per degree increase in temperature has been reported in convective clouds over India.

description: This article attempts to substantiate the epistemological boundaries of Mialaret’s “Cause Pedagogy”. On this basis, the authors investigate the conditions under which the teacher can be the “cause” of learning within the context of his pedagogical interaction with the learner. In order to answer this question, the first delineation highlights the role of the teacher within the pedagogical relationship with the learners. Subsequently, after extensive study of Mialaret’s texts and related bibliographical sources, it can be concluded that the teacher can be the “cause” of learning: (a) when identifying and defining his pedagogical relationship with the learner, (b) when responding to effectiveness within the complexity of his role, c) when he uses his scientific knowledge of pedagogy in daily teaching, and finally d) when he uses information from other sciences to optimize teaching.

description: Complex networks are used to describe a broad range of disparate social systems and natural phenomena, from power grids to customer segmentation to human brain connectome. Challenges of parametric model specification and validation inspire a search for more data-driven and flexible nonparametric approaches for inference of complex networks. In this paper we discuss methodology and R implementation of two bootstrap procedures on random networks, that is, patchwork bootstrap of Thompson et al. (2016) and Gel et al. (2017) and vertex bootstrap of Snijders and Borgatti (1999). To our knowledge, the new R package snowboot is the first implementation of the vertex and patchwork bootstrap inference on networks in R. Our new package is accompanied with a detailed user's manual, and is compatible with the popular R package on network studies igraph. We evaluate the patchwork bootstrap and vertex bootstrap with extensive simulation studies and illustrate their utility in application to analysis of real world networks.

key messages

description: This fourth deliverable of WP6 aims to contribute to the dissemination of project results related to promising strategies of using tree/shrub leaves for livestock feeding. This includes the development of appropriate communication and application tools. Results from various tasks were regularly shared with farmers through innovation platforms (IPs) and dissemination days, mainly organised by WP2, as well as workshops by WP6. These meetings allowed the WP6 teams in the three intervention countries to convey key messages with practical, site-specific recommendations on why and how to include woody fodder in animal feed rations in each participating country. Stakeholder reactions were documented, followed by discussions, joint conclusions and identification of key messages for further dissemination via leaflets and other classical materials that can easily be distributed. Necessary subsequent steps were also planned or decided during these meetings.

This deliverable also includes the summary of scientific articles, reports, and students’ theses realised within the project, as well as the publication of updates on the project's website. These outreach materials rather target the scientific and R&D community in order to stimulate discussion and create synergies across different projects and regions.

description: We present the analysis of grating spectra of the Narrow Line Seyfert 1 Galaxy IRAS 17020+4544 observed by XMM-Newton in 2004 and 2014. In a previous work on these data, we reported the discovery of a multi-component ultra-fast outflow that is capable of producing feedback in the host galaxy. We also reported the presence of a slow, multi-phase warm absorber. In this follow-up paper, we confirm that this low velocity absorber can be modeled by four layers of ionized gas. When crossing our line-of-sight, this gas presents peculiar changes along the 10-yr time scale elapsed between the two observations obtained by XMM-Newton. While two of such components are almost stationary, the other two are found inflowing and outflowing with significant variations in velocity and ionization between 2004 and 2014. The luminosity and spectral shape of the central source remain practically unvaried. We propose that the presence of the fast wind and of the variable warm absorber can be interpreted in the framework of a `shocked outflow', where the peculiar variability pattern of the low-velocity components might arise from instabilities in the shocked gas.

description: We present a novel method for the calculation of the fractal dimension of boundaries in dynamical systems, which is in many cases many orders of magnitude more efficient than the uncertainty method. We call it the Output Function Evaluation (OFE) method. The OFE method is based on an efficient scheme for computing output functions, such as the escape time, on a one-dimensional portion of the phase space. We show analytically that the OFE method is much more efficient than the uncertainty method for boundaries with $D<0.5$, where $D$ is the dimension of the intersection of the boundary with a one-dimensional manifold. We apply the OFE method to a scattering system, and compare it to the uncertainty method. We use the OFE method to study the behavior of the fractal dimension as the system's dynamics undergoes a topological transition.

description: This comparative study, based on quantitative data, studied,with two questionnaires, internet communication and interaction between peers not attending the Integration Program of the Department of the School Classes E \ F grade (control group) compared with peers ( of the same grades) attending the Integration Program of the Department of the School, (experimental group).With the third questionnaire it was mirrored and investigated whether students who communicate and interact via the Internet, strengthen self-concept and selfesteem as compared to students who do not communicate and interact online with the use of tools such as different forums and facebook, chatting and special blogs.Alongside it was investigated whether students of both groups (in Section Integration and non studying in Integration Department) who use the Internet are different as regards self-concept / self-esteem. The main conclusion of the study showed that the peer groups of disabled children perform an important social function since they help the child to see the image of himself through relationships with peers. The present study shows that the way in which contemporary family socializes its members and the school educates students reinforce the role of the media and peer groups in the socialization of disabled children.

A deep XMM-Newton look on the thermally emitting isolated neutron star RX J1605.3+3249

description: Previous XMM-Newton observations of the thermally emitting isolated neutron star RX J1605.3+3249 provided a candidate for a shallow periodic signal and evidence of a fast spin down, which suggested a high dipolar magnetic field and an evolution from a magnetar. We obtained a large programme with XMM-Newton to confirm its candidate timing solution, understand the energy-dependent amplitude of the modulation, and investigate the spectral features of the source. We performed extensive high-resolution and broadband periodicity searches in the new observations, using the combined photons of the three EPIC cameras and allowing for moderate changes of pulsed fraction and the optimal energy range for detection. A deep $4σ$ upper limit of $1.33(6)\%$ for modulations in the relevant frequency range conservatively rules out the candidate period previously reported. Blind searches revealed no other periodic signal above the $1.5\%$ level $(3σ$) in any of the four new observations. While theoretical models fall short at physically describing the complex energy distribution of the source, best-fit X-ray spectral parameters are obtained for a fully or partially ionized neutron star hydrogen atmosphere model with $B=10^{13}$ G, modified by a broad Gaussian absorption line at $385\pm10$ eV. The deep limits from the timing analysis disfavour equally well-fit double temperature blackbody models where both the star surface and small hotspots contribute to the X-ray flux of the source. We identified a low significance ($1σ$) temporal trend on the parameters of the source in the analysis of RGS data dating back to 2002, which may be explained by unaccounted calibration issues and spectral model uncertainties. The new dataset also shows no evidence of the previously reported narrow absorption feature at $\sim570$ eV, whose possible transient nature disfavours an atmospheric origin.

description: A model consisting of a single massless scalar field with a topological coupling to a pure gauge field is defined and studied. It possesses an SL(2,Z) symmetry as a consequence of the gauge invariance. We propose that by adding impurities the model can be used to describe transitions between Quantum Hall plateaux. This leads to a correlation length exponent of 20/9, in excellent agreement with the most recent experimental measurements.

description: ABSTRACTBackground: In tissue engineering, scaffold characteristics play an important role in the biological interactionsbetween cells and the scaffold. Cell adhesion, proliferation, and activation depend on materialproperties used for the fabrication of scaffolds.Objective: In the present investigation, we used collagen with proper characteristics including mechanicallystability, biodegradability and low antigenicity. Optimization of the scaffold was done by immobilizationof alkaline phosphatase on the collagen surface via cross-linking method, because this enzyme isone of the most important markers of osteoblast, which increases inorganic phosphate concentration andpromote mineralization of bone formation.Methods: Alkaline phosphatase was immobilized on a collagen surface by 1-ethyl-3-(dimethylaminopropyl)carbodiimide hydrochloride, as a reagent. Then, rat mesenchymal stem cells were cultured in osteogenicmedium in control and treated groups. The osteogenesis-related genes were compared between treatments(differentiated cells with immobilized alkaline phosphatase/collagen scaffold) and control groups(differentiated cells on collagen surface without alkaline phosphatase) on days 3 and 7 by quantitativereal-time PCR (QIAGEN software).Results: Several genes, including alkaline phosphatase, collagen type I and osteocalcine associated withcalcium binding and mineralization, showed upregulation in expression during the first 3 days, whereastumor necrosis factor-α, acting as an inhibitor of differentiation, was down-regulated during osteogenesis.Conclusion: Collagen scaffold with immobilized alkaline phosphatase can be utilized as a good candidatefor enhancing the differentiation of osteoblasts from mesenchymal stem cells.
The critical earthquake concept applied to mine rockbursts with time-to-failure analysis

description: We report new tests of the critical earthquake concepts performed on rockbursts in deep South African mines. We extend the concept of an optimal time and space correlation region and test it on the eight main shocks of our catalog provided by ISSI. In a first test, we use the simplest signature of criticality in terms of a power law time-to-failure formula. Notwithstanding the fact that the search for the optimal correlation size is performed with this simple power law, we find evidence both for accelerated seismicity and for the presence of logperiodic behavior with a prefered scaling factor close to 2. We then propose a new algorithm based on a space and time smoothing procedure, which is also intended to account for the finite range and time mechanical interactions between events. This new algorithm provides a much more robust and efficient construction of the optimal correlation region, which allows us the use of the logperiodic formula directly in the search process. In this preliminary work, we have only tested the new algorithm on the largest event on the catalog. The result is of remarkable good quality with a dramatic improvement in accuracy and robustness. This confirms the potential importance of logperiodic signals. Our study opens the road for an efficient implemention of a systematic testing procedure of real-time predictions.

description: Deep reinforcement learning (deep RL) has achieved superior performance in complex sequential tasks by using deep neural networks as function approximators to learn directly from raw input images. However, learning directly from raw images is data inefficient. The agent must learn feature representation of complex states in addition to learning a policy. As a result, deep RL typically suffers from slow learning speeds and often requires a prohibitively large amount of training time and data to reach reasonable performance, making it inapplicable to real-world settings where data is expensive. In this work, we improve data efficiency in deep RL by addressing one of the two learning goals, feature learning. We leverage supervised learning to pre-train on a small set of non-expert human demonstrations and empirically evaluate our approach using the asynchronous advantage actor-critic algorithms (A3C) in the Atari domain. Our results show significant improvements in learning speed, even when the provided demonstration is noisy and of low quality.

description: As additional neutron scattering experiments are performed on a variety of high temperature superconducting compounds it appears that magnetic incommensuration is a phenomenon common to all of the samples studied. The newest experimental results indicate that incommensurate peaks exist at momentum ${\bf q}=π(1,1\pmδ)$ and $π(1\pmδ,1)$ in $La_{2-x}Sr_xCuO_4}$ (LSCO) and ${\rm YBa_2Cu_3O_{7-δ}}$ (YBCO). The dependence of $δ$ with hole doping appears to be similar in both materials. In addition, new ARPES data for LSCO as a function of doping show that its Fermi surface is qualitatively similar to the one of YBCO, contrary to what was previously believed. Early theoretical attempts to explain LSCO and YBCO behavior usually relied on one- or three-band Hubbard models or the t-J model with electron hopping beyond nearest-neighbor and with different parameter values for each material. In this paper it is shown that using a one band Hubbard U-t-$t'$ model with a unique set of parameters, U/t=6 and $t'$/t=-0.25, good agreement is obtained between computational calculations and neutron scattering and ARPES experiments for LSCO and YBCO. It is also shown that using a more negative $t'$/t will induce short-range magnetic incommensuration along the diagonal direction in the Brillouin zone, in qualitative disagreement with the experimental results. At the finite temperatures of the present Monte Carlo simulation it is also observed that in this model the tendency to incommensuration appears to be more related to the shape of the two-dimensional Fermi surface and the strength of the interaction, rather than to charge order.

description: This paper discusses the context for critical science education as the outcome of the synthesis of Critical Theory of theFrankfurtSchool, British Cultural Studies and Critical Pedagogy. In our work, we study how critical pedagogues Joe Kincheloe and Peter McLaren suggested the introduction of criticality in science education by combining the analysis for science and capitalism with theorizations about the politics of social movements. Finally, we propose how critical science education can constitute itself as a new research program in the didactics of science and simultaneously can change the content of the teaching of science.

In the same Q^2 range, N_{obs} =4 charged current candidates are observed where the expectation is N_{DIS} = 1.77 \pm 0.87 events. The probability P(N \geq N_{obs}) that the DIS model signal N fluctuates to N \geq N_{obs} in a random set of experiments is 6 10^{-3} for neutral current and 0.14 for charged current. The difference in the observed and expected number of Neutral Current events is mostly due to events at large masses M = sqrt{xs} in which the positron is backscattered at large y = Q^2/M^2.

description: In the present study, skills and knowledge of the writing were evaluated with informal tests based on the curriculum to pupils with high school performance, aged 9-12. The aim was to explore what the pupils know and what they can do individually and as a group, in relation to their optimal development and the curriculum objectives. 22 students were tested individually and 34 students were tested in the group level. We thought that such investigation will give us the opportunity for useful conclusions for the evaluation process and for the ability of informal tests to describe pupils’ deficits and abilities in writing effectively.

description: This paper deals with $(K_1, K_2)$-quasiregular mappings. It is shown, by Morrey's Lemma and isoperimetric inequality, that every $(K_1, K_2)$-quasiregular mapping satisfies a Hölder condition with exponent $α$ on compact subsets of its domain, where \begin{align} α=\begin{cases} 1/K_1, & \text{for } K_1>1, \\ \text{any positive number less than } 1, & \text{for } K_1=1 \text{ and } K_2>0, \\ 1, & \text{for } K_1=1 \text{ and } K_2=0, \\ 1, & \text{for } K_1<1,\\ \end{cases} \end{align} Differentiability almost everywhere of $(K_1, K_2)$-quasiregular mappings is also derived.

description: We conjecture that for a wide class of interacting particle systems evolving in discrete time, namely conservative cellular automata with piecewise linear flow diagram, relaxation to the limit set follows the same power law at critical points. We further describe the structure of the limit sets of such systems as unions of shifts of finite type. Relaxation to the equilibrium resembles ballistic annihilation, with ``defects'' propagating in opposite direction annihilating upon collision.

Sliding Phases in XY-Models, Crystals, and Cationic Lipid-DNA Complexes

description: We predict the existence of a totally new class of phases in weakly coupled, three-dimensional stacks of two-dimensional (2D) XY-models. These ``sliding phases'' behave essentially like decoupled, independent 2D XY-models with precisely zero free energy cost associated with rotating spins in one layer relative to those in neighboring layers. As a result, the two-point spin correlation function decays algebraically with in-plane separation. Our results, which contradict past studies because we include higher-gradient couplings between layers, also apply to crystals and may explain recently observed behavior in cationic lipid-DNA complexes.

description: According to the greek formal curriculum for Mathematics in primary education, the domain of percentage is introduced in 5th and 6th grade and its teaching is concluded during the first year of secondary school. The concept of percentage can be constructed through different lessons such as fractions, decimals, ratio and analogy. Percentages should be taught via lessons which reflect every day situations and problem solving, inasmuch as they allow comparisons of disparate situations and are considered as symbolic representations of the hundredth in decimals and fractions. On the other hand, anxiety causes feelings of unease and occurs unconsciously so it cannot be addressed immediately. More specifically, mathematics anxiety is connected to combinatory unpleasant feelings elicited by children’s low performance in problem solving tasks. The purpose of this study is to investigate how students who attend the first grade of secondary school understand the concept of percentage. For this reason, problem solving tasks were analysed because a link between understanding percentages and specific characteristics of mathematics anxiety has been established in recent studies.

description: The composite Fermion (CF) picture offers a simple intuitive way of understanding many of the surprising properties of a strongly interacting two-dimensional electron fluid in a large magnetic field. The simple way in which the mean field CF picture describes the low lying bands of angular momentum multiplets for any value of the applied magnetic field is illustrated and compared with the results of exact numerical diagonalization of small systems. The justification of the success of the CF approach is discussed in some detail, and a CF hierarchy picture of the incompressible quantum fluid states is introduced. The CF picture is used to understand the energy spectrum and photoluminescence of systems containing both electrons and valence band holes.

description: We demonstrate improvements to the cooling power of broad bandwidth (10 GHz) microwave attenuators designed for operation at temperatures below 100 mK. By interleaving 9-$μ$m thick conducting copper heatsinks in between 10-$μ$m long, 70-nm thick resistive nichrome elements, the electrical heat generated in the nichrome elements is conducted more readily into the heatsinks, effectively decreasing the thermal resistance between the hot electrons and cold phonons. For a 20 dB attenuator mounted at 20 mK, a minimum noise temperature of $T_{n} \sim$ 50 mK was obtained for small dissipated powers ($P_d

description: We consider micro- and macro- phase separation in blends of AB and BC diblock copolymers. We show that, depending on architecture, a number of phase diagram topologies are possible. Microphase separation or macrophase separation can occur, and there are a variety of possible Lifshitz points. Because of the rich parameter space, Lifshitz points of multiple order are possible. We demonstrate Lifshitz points of first and second order, and argue that, in principle, up to 5th order Lifshitz points are possible.

description: The present study discusses ways through which inclusive education can be promoted in primary education inGreece. Particularly, it suggests that Universal Design for Learning (UDL) and Total Quality in Education (TQE) create an environment where inclusion can flourish. The research took place at a primary school, with the participants being the students of 1st and 4th grade, their parents and the teachers. Τhe qualitative research methodology was followed. The process of research was divided in three phases. The first one was the primary evaluation of the conditions of the two classes, regarding the degree of evolvent of inclusive education. The second one was the intervention according to the principals of UDL and TQE and the last one was the final evaluation of the intervention. Each philosophy separately, but at the same time simultaneously and in combination with the other one, they created the conditions for the reduction of children’s marginalization, the increase of their everyday participation by overtaking the barriers, the provision of equal opportunities to all and eventually the promotion of inclusion.

description: The paper aims, through the interpretive perspective of the Theory of Planned Behavior, to examine teachers’ attitudes, subjective norms and perceived behavioral control with regard to new media literacies, as defined by Henry Jenkins, primarily in the general context and secondarily in literature’s field. The background behind the research is the proven importance of reading for pleasure for both educational and personal development, coupled with the fact that the time for literature reading internationally, especially among young people, is steadily decreasing. Given that the critical age for the development of literary reading habits is the first school years, and as technology has penetrated young people’s lives to the point of existing enormous discrepancies between the students’ daily practices and the educational ones, we presume that exploiting the new media for stimulating literary interest could be crucial. The most important factor in this process is the teacher who mediates the literature lesson. The questionnaire was distributed to active teachers, upon graduation and postgraduate students of the Pedagogical School of the National and Kapodistrian University of Athens (116 questionnaires in total). Our rationale was that, according to the aforementioned theory, the research’s findings could be a predictive factor for teachers’ future pedagogical choices and practices, with regard to the integration of new media into the teaching of literature, as a means of enhancing students’ positive predisposition towards literature and reading for pleasure.
