description: Print literature is gradually supplanted by digital texts, which occupy an increasing part of the market. Digital texts excel their print antecedents in navigation features, various types of interactivity and access to web resources, elements that transform the reader to a “wreader” or even a “prosumer”, meaning a co-creator. Nowadays, an even more revolutionary evolution takes place in digital environments: transmedial narrative. It refers to a process in which integral elements of a story are systematically dispersed across multiple distribution channels, in order to create a unified and coordinated entertainment experience. The aim of the present study is to examine the status of Greek children’s and young adults’ literature in the digital era, regarding the principles set by radical theory. According to the radical theory the three fundamental properties of literature under the influence of new technologies are: interactivity, connectivity and accessibility. Researchers have proven that the influence of the digital era on the illustrated children's books internationally is quite remarkable. In Greece, although accessibility and interactivity are well supported, connectivity is still residual. To fill in the blank of the research, we aim to define Greek children’s and young adults’ literature’s place among the novelties of the cyber universe. We examine books whose titles contain the word “internet”, or any relative or contiguous ones, in order to detect features of radicalism, cyber aesthetics or even more complex interactive relations towards transmediality. According to our findings, the Internet as a thematic axis does not ensure the presence of innovative features, either in the form or in the content of the books. Interactivity as defined by the radial theory lacks and there are not spotted any attempts by the editors to develop or expand the texts on other platforms or media. The young reader's exploratory, participatory and interactive behavior is not encouraged. Greek children’s literature field seems to be reserved, not yet mature enough to take daring steps ahead.

description: This article examines the extent of incorporation, association and exploitation of Literary Theory and, in particular, the theories focusing on the decoding of narrative mechanisms (narratology) in the teaching of literature both in secondary education and also in creative-writing adult workshops. These spaces are seen as two distinct spaces of knowledge, which, however, function complimentarily in the effort of pupils and adult students to familiarise themselves with the literary code, theoretically and practically. This study emphasises the importance of narratology as a useful methodological and interpretive instrument, which does not approach the literary text formalistically but constitutes a semantic indicator of the structure and language of the aesthetic discourse of the literary work and can function as a means of enhancing creativity and experimentation, both in the classroom and in the creative-writing workshops. Consequently, this article gives answers to the reasons why narratology is indispensable for approaching literary works, while, at the same time, it proposes a redefinition of teachers' attitudes towards it, since narratology can aid in the cultivation of creative expression.

description: Background Patients with atrial fibrillation (AF) are often treated with antiarrhythmic drugs (AADs) to maintain sinus rhythm and with heart rate-lowering drugs to achieve optimal rate control. In this study we investigated trends in the use of AADs and rate control drugs in Finnish patients with AF. Methods and results The Finnish AntiCoagulation in Atrial Fibrillation (FinACAF) study is a nationwide study including all patients with AF in Finland from 2007 to 2018. The number of AAD purchases and the proportions of all prevalent AF patients in a certain year of interest were calculated. In total, 391030 AF patients were identified between 2007 and 2018, and 39816 (10.2%) of them had purchased either class I or III AADs. The proportion of patients using class I and III AADs decreased from 8.6% to 6.3%. Flecainide and amiodarone were the most often used AADs. The use of flecainide and amiodarone decreased from 4.9% to 3.9% and 1.9% to 1.5%, respectively. The proportion of patients on beta-blockers remained stable at 75%. Dronedarone became available in 2011 when it also was the most used (0.8% of patients), but the use decreased thereafter. The use of sotalol and digoxin decreased from 1.5% to 0.6% and 24.6% to 11.0% over the study period. Conclusion The number of AAD purchases increased alongside with the increasing prevalence of AF, whereas the proportion of AF patients on class I and III AADs and digoxin decreased between 2007 and 2018. Flecainide remained the most used AAD followed by amiodarone.

description: The Go model is extended to the case when the non-native contact energies may be either attractive or repulsive. The folding temperature is found to increase with the energy of non-native contacts. The repulsive non-native contact energies may lead to folding at T=0 for some two-dimensional sequences and to reduction in complexity of disconnectivity graphs for local energy minima.

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 explore interpretations of the anomaly observed by H1 and ZEUS at HERA in deep-inelastic e^+ p scattering at very large Q^2. We discuss the possibilities of new effective interactions and the production of a narrow state of mass 200 GeV with leptoquark couplings. We compare these models with the measured Q^2 distributions: for the contact terms, constraints from LEP2 and the Tevatron allow only a few choices of helicity and flavour structure that could roughly fit the HERA data. The data are instead quite consistent with the Q^2 distribution expected from a leptoquark state. We study the production cross sections of such a particle at the Tevatron and at HERA. The absence of a signal at the Tevatron disfavours the likelihood that any such leptoquark decays only into e^+ q. We then focus on the possibility that the leptoquark is a squark with R-violating couplings. In view of the present experimental limits on such couplings, the most likely production channels are e^+d -> scharm_L or perhaps e^+d->stop, with e^+s->stop a more marginal possibility. Possible tests of our preferred model include the absence both of analogous events in e^- p collisions and of charged current events, and the presence of detectable cascade decays whose kinematical signatures we discuss. We also discuss the possible implications for K->pi nu nubar, neutrinoless double-beta decay, the Tevatron and for e^+ e^- ->q qbar and neutralinos at LEP2.

description: The parameters choosing (such as probabilities of choosing X-basis or Z-basis, intensity of signal state and decoy state, etc.) and system calibrating will be more challenging when the number of users of a measurement-device-independent quantum key distribution(MDI-QKD) network becomes larger. At present, people usually use optimization algorithms to search the best parameters. This method can find the optimized parameters accurately but may cost lots of time and hardware resources. It's a big problem in large scale MDI-QKD network. Here, we present a new method, using Back Propagation Artificial Neural Network(BPNN) to predict, rather than searching the optimized parameters. Compared with optimization algorithms, our BPNN is faster and more lightweight, it can save system resources. Another big problem brought by large scale MDI-QKD network is system recalibration. BPNN can support this work in real time, and it only needs to use some discarded data generated from communication process, rather than require us to add additional devices or scan the system

Year: 2025

description: International financial relations refer to the economic interactions between countries, encompassing trade, investment flows, and monetary policies. These relations are essential for fostering global economic growth, development, and cooperation, but they also present a range of challenges. Imbalances in power, financial instability, and disparities in wealth distribution are some of the persistent issues that can hinder equitable development. The complexities of international financial systems, including issues such as currency volatility, trade imbalances, and national debt, further complicate the global economic landscape. Additionally, globalization and technological advancements introduce both opportunities and risks, requiring countries to navigate an increasingly interconnected and volatile environment. This paper explores the key problems within international financial relations and discusses potential solutions, with a focus on fostering fairness, resilience, and sustainability in the global economy. It examines the role of multilateral institutions, the need for regulatory coordination, and the importance of international collaboration in addressing the challenges of the modern global financial system. Ultimately, the paper highlights the importance of balancing economic integration with equitable growth to ensure a stable and prosperous future for all nations.

description: Different types of training data have led to numerous schemes for supervised classification. Current learning techniques are tailored to one specific scheme and cannot handle general ensembles of training data. This paper presents a unifying framework for supervised classification with general ensembles of training data, and proposes the learning methodology of generalized robust risk minimization (GRRM). The paper shows how current and novel supervision schemes can be addressed under the proposed framework by representing the relationship between examples at test and training via probabilistic transformations. The results show that GRRM can handle different types of training data in a unified manner, and enable new supervision schemes that aggregate general ensembles of training data.

description: Based on first-principles calculations and k .p effective models, we report physical properties of ferroelectric-like hexagonal polar metals with P63mc symmetry, which are distinct from those of conventional metals with spatial inversion symmetry. Spin textures exist on the Fermi surface of polar metals (e.g. ternary LiGaGe and elemental polar metal of Bi) and spin-momentum locking exist on accidental Dirac cones on the sixfold rotational axis, due to the spin-orbit coupling and lack of inversion symmetry in polar space group. This effect has potential applications in spin-orbitronics. Dirac points are also predicted in LiGaGe.

description: We numerically investigate slow dynamics of a binary mixture of ultrasoft particles interacting with the generalized Hertzian potential. If the softness parameter, $α$, is small, the particles at high densities start penetrating each other, form clusters, and eventually undergo the glass transition. We find multiple cluster-glass phases characterized by different number of particles per cluster, whose boundary lines are sharply separated by the cluster size. Anomalous logarithmic slow relaxation of the density correlation functions is observed in the vicinity of these glass-glass phase boundaries, which hints the existence of the higher-order dynamical singularities predicted by the mode-coupling theory. Deeply in the cluster glass phases, it is found that the dynamics of a single particle is decoupled from that of the collective fluctuations.

description: In a closed economic system, money is conserved. Thus, by analogy with energy, the equilibrium probability distribution of money must follow the exponential Gibbs law characterized by an effective temperature equal to the average amount of money per economic agent. We demonstrate how the Gibbs distribution emerges in computer simulations of economic models. Then we consider a thermal machine, in which the difference of temperatures allows one to extract a monetary profit. We also discuss the role of debt, and models with broken time-reversal symmetry for which the Gibbs law does not hold.

Open data structure

The database for this publication consists of two main folders: Acoustic Recording Data and Synchrotron X-ray Measurements. The subsets within the synchrotron X-ray data are named according to sample identification, printing conditions, and alloy composition. For example, the label Ti0Fe_C_L12 indicates a sample composed of Ti-6Al-4V alloy with no Fe addition. The "C" denotes conduction mode melting with medium energy density, and "L12" refers to the 12th layer of the printed part.

The Acoustic Data are similarly organized based on alloy composition. Within each folder, the labels "CM" and "KM" indicate the melting regime: conduction mode and keyhole mode, respectively. The accompanying numbers specify the corresponding layer of the build. This structured naming convention facilitates efficient navigation and interpretation of the dataset. The codes used for data processing and analysis are provided in the following repository.

description: The efficiency and accuracy of the Euler‐Lagrange/discrete element method model were investigated. Accordingly, the stiffness coefficient and fluid time step were changed for different particle numbers and diameters. To derive the optimum parameters for simulations, the obtained results were compared with the measurements. According to the results, the application of higher stiffness coefficients improves the simulation accuracy slightly, however, the average computing time increases exponentially. For time intervals larger than 5 ms, the results indicated that the average computation time is independent of the applied fluid time step, while the simulation accuracy decreases extremely by increasing the size of the fluid time step. Nevertheless, using time steps smaller than 5 ms leads to negligible improvements in the simulation accuracy, though to an exponential rise in the average computing time.
Unconventional orbital ordering and emergent dimensional reduction in fulleride superconductors

description: Non-local order parameters in space-time are proposed to characterize the unconventional orbital-selective conducting state in fulleride superconductors, called the Jahn-Teller metal. In previous works, it has been argued that this state can be interpreted as a spontaneous orbital-selective Mott state, in which the electrons in two of the three $t_{1u}$ molecular orbitals are localized, while those in the third one are metallic. Here, based on the realistic band structure for fullerides, we provide a systematic study of nonlocal order parameters and characterize the Jahn-Teller metal, for which there exists no one-body local order parameter in contrast to conventional orderings. It is shown that the Mottness, or integer filling nature for each orbital due to strong correlation effects, is a relevant feature of the present orbital order. The local orbital moment thus vanishes and the static distortion associated with a conventional orbital moment is absent. Transport characteristics are also investigated, and it is found that the dimensionality is effectively reduced from three to two at low energies, while the cubic nature is recovered at high energies. This accounts for the high upper critical field observed in the superconducting state of the fcc fullerides inside the Jahn-Teller metal regime.

description: Origami describes rules for creating folded structures from patterns on a flat sheet, but does not prescribe how patterns can be designed to fit target shapes. Here, starting from the simplest periodic origami pattern that yields one degree-of-freedom collapsible structures, we show that scale-independent elementary geometric constructions and constrained optimization algorithms can be used to determine spatially modulated patterns that yield approximations to given surfaces of constant or varying curvature. Paper models confirm the feasibility of our calculations. We also assess the difficulty of realizing these geometric structures by quantifying the energetic barrier that separates the metastable flat and folded states. Moreover, we characterize the trade-off between the accuracy to which the pattern conforms to the target surface, and the effort associated with creating finer folds. Our approach enables the tailoring of origami patterns to drape complex surfaces independent of absolute scale, and quantify the energetic and material cost of doing so.

description: The scope of this article is to explore the body of Aeschylus’ play Prometheus Bound and to analyze the meanings attributed to the concept of teaching and learning. According to Aeschylus, all of man’s technical and coginitive skills derive from Prometheus: especially teaching at a very early stage using specific techniques and skills such as guidance, education, the ability to improve, managing student behavior, setting goals, and understanding. It seems that the history of the duality ‘teaching-learning’ is deeply rooted in the ancient theatrical play Prometheus Bound. It appears that the educational role of ‘fire’ and ‘time’ is of such great significance in Aeschylus’ philosophical conception that constitutes them as the primary principles over many others. And Prometheus, the ontological equivalent of these principles, teaches mankind to teach itself, through sciences and disciplines such as mathematics, geography, astronomy, and medicine.

description: This paper uses population synthesis to investigate the possible origin of isolated millisecond pulsars (IMSPs) as born from the coalescence of a neutron star (NS) and a white dwarf (WD). Results show that the galactic birth - rate of IMSPs is likely to lie between $5.8\times10^{-5}$ $\rm yr^{-1}$ and $2.0\times10^{-4}$ $\rm yr^{-1}$, depending on critical variables, such as the stability of mass transfer via the Roche lobe and the value of kick velocity. In addition to this, this paper estimates that the solar mass of IMSPs can range from $1.5$ and 2.0 $M_{\odot}$, making them more massive than other 'normal' pulsars. Finally, the majority of IMSPs in our simulations have spin periods ranging from several to 20 milliseconds, which is consistent with previous observations.

description: Mit der Standortskartierung der neuen Bundesländer wird dem jeweiligen Bewirtschafter einer Fläche eine Hilfestellung an die Hand gegeben, um die Leistungsfähigkeit eines Standortes einzuschätzen. Teilweise kann es hierbei jedoch zu abweichenden Bewertungen bezüglich der Nährkrafteigenschaften eines Standortes kommen, begründet mit der Wüchsigkeit des aufstockenden Bestandes und der vorgefundenen Vegetation. Dem Ziel der Arbeit ausgewählte Standorte des Reviers Jerchel auf ihre standörtlichen Wachstumsfaktoren hin zu untersuchen, wird mit neu angelegten Bodengruben zur Ausweisung der entsprechenden Feinbodenformen, Vegetationsaufnahmen, der Erfassung ertragskundlicher Daten und der Auswertung übergeordneter klimatischer Daten begegnet. Die Methodik orientiert sich hierbei an den Vorgaben der SEA 95, der Standortserkundungsanleitung der neuen Bundesländer. Nachdem die Ergebnisse zunächst flächenbezogen in eine Gesamteinordnung gebracht werden, so dass insbesondere je eine individuelle Empfehlung bezüglich der weiteren Bewirtschaftung des Standortes ausgegeben werden kann, folgt eine Auswertung über die offensichtlich allgemein gültigen Abweichungen gegenüber der ursprünglichen Standortskartierung. So lässt sich insgesamt für die fünf untersuchten Standorte festhalten, dass während der Ursprungskartierung zwar nur an drei Standorten tatsächlich eine falsche Feinbodenform und/oder Nährkraftstufe ausgewiesen wurde, jedoch individuell für die anderen Zwei zumindest plausible Erklärungen für Abweichungen zu Vegetationsmerkmalen und besseren Bonitäten aufgezeigt werden können. Die individuellen Eindrücke der Bestände sind insofern immer in Ergänzung zur jeweiligen Kartierung zu sehen, um eine umfassende, der jeweiligen Teilfläche gerecht werdende Entscheidung für die weitere Bewirtschaftung treffen zu können.

description: We study the $η_c$ photoproduction in $ep$ collisions in this paper. The short-distance coefficients for $c\bar{c}(^1S_0^{[1]})$, $c\bar{c}(^1S_0^{[8]})$, $c\bar{c}(^3S_1^{[8]})$, and $c\bar{c}(^1P_1^{[8]})$ photoproductions are evaluated at leading order in $α_s$ expansion, where the color-singlet contribution is achieved for the first time. We have carefully analyzed different kinematic distributions of the cross sections and found that the color-singlet contribution is considerably suppressed comparing with the color-octet parts. This feature renders the $η_c$ photoproduction process an ideal laboratory to test the color-octet mechanism in nonrelativistic QCD. By taking different sets of long-distance matrix elements, we have observed some apparently distinguishable predictions, which can be utilized to scrutinize the validity of these matrix elements.

description: We obtained, for the first time, astrometrically registered maps of the 22.2 GHz H2O and 42.8, 43.1, and 86.2 GHz SiO maser emission toward the semiregular b-type variable (SRb) R Crateris, at three epochs (2015 May 21, and 2016 January 7 and 26) using the Korean Very-long-baseline Interferometry Network. The SiO masers show a ring-like spatial structure, while the H2O maser shows a very asymmetric one-side outflow structure, which is located at the southern part of the ring-like SiO maser feature. We also found that the 86.2 GHz SiO maser spots are distributed in an inner region, compared to those of the 43.1 GHz SiO maser, which is different from all previously known distributions of the 86.2 GHz SiO masers in variable stars. The different distribution of the 86.2 GHz SiO maser seems to be related to the complex dynamics caused by the overtone pulsation mode of the SRb R Crateris. Furthermore, we estimated the position of the central star based on the ring fitting of the SiO masers, which is essential for interpreting the morphology and kinematics of a circumstellar envelope. The estimated stellar coordinate corresponds well to the position measured by Gaia.

description: Here, we report a study on the radiation resistance enhancement of Gd2Zr2O7 nanograin ceramics, in which amorphization, cell volume expansion and multi-stage helium (He) bubble formation are investigated and discussed. Gd2Zr2O7 ceramics with a series of grain sizes (55-221 nm) were synthesized and irradiated by 190 keV He ion beam up to a fluence of 5x10^17 ions/cm2. Both the degree of post irradiation cell volume expansion and the amorphization fraction appear to be size dependent. As the average grain size evolves from 55 to 221 nm, the degree of post irradiation cell volume expansion increases from 0.56 to 1.02 %, and the amorphization fraction increases from 6.8 to 11.1 %. Additionally, the threshold He concentrations (at. %) of bubbles at different formation stages and locations, including (1) bubbles at grain boundary, (2) bubble-chains and (3) ribbon-like bubbles within the grain, are all found to be much higher in the nanograin ceramic (55 nm) compared with that of the submicron sample (221 nm). We conclude that grain boundary plays a critical role in minimizing the structural defects, and inhibiting the multi-stage He bubble formation process.

description: This paper aims to highlight poetry’s position in the latest curricula for primary and secondary education, designed and implemented in 2011. My primary goal here is to bring to the fore the most important characteristics of the NCS through the perspectives of Critical Pedagogy, Cultural studies and Reader-Response literary theories. My attempt to detect and present the groundbreaking aspects of the new curricula is organised around three main points pertaining to the teaching of poetry in school: a) the new teaching context delimited and defined by the NCS; b) the reinstatement of the student to the position of reader; c) the connection of poetry itself to the lived experiences of students within their concurrent cultural and temporal reality, and the consequent recovery of the historicity of the poetic texts.

description: We report an optomechanical system with two dielectric membranes inside a Fabry-Perot cavity. The cavity resonant frequencies are measured in such a two-membrane-in-the-middle system, which show an interesting band-structure-like diagram. This system exhibits great controllability on the parameters of the system. The positions and angles of each membrane can be manipulated on demand by placing two membranes inside the cavity separately. The eigenfrequencies of the vibrational modes of the membranes can also be tuned individually with piezoelectricity. This scheme could be straightforwardly extended to multiple-membrane-in-the-middle systems, where more than two membranes are involved. Such a well controllable multiple membrane optomechanical system provides a promising platform for studying nonlinear and quantum dynamical phenomena in multimode optomechanics with distinct mechanical oscillators.

description: The results of experimental and theoretical studies of zero-bias anomaly (ZBA) in the Pb-oxide-n-InAs tunnel structures in magnetic field up to 6T are presented. A specific feature of the structures is a coexistence of the 2D and 3D states at the Fermi energy near the semiconductor surface. The dependence of the measured ZBA amplitude on the strength and orientation of the applied magnetic field is in agreement with the proposed theoretical model. According to this model, electrons tunnel into 2D states, and move diffusively in the 2D layer, whereas the main contribution to the screening comes from 3D electrons.

description: School space is particularly important and has the potential to influence the way a person teaches or learns at school. The main purpose of this research is to investigate the views of the nursery students on the importance of the school space in the learning process. This questionnaire was distributed to active preschool educators working in public and private nursery schools in the Central Macedonia Region during November - December 2017. The questionnaire analysis was carried out with SPSS 22.0. The results of the survey were particularly important. The teachers who participated in the research consider the participation of children in the reorganizations of the area that are part of the educational process and the integration of the space into the spontaneous and organized game favor the development of positive interactions and the creativity of the children. Finally, the formation and exploitation of space contributes positively to the learning process as it enhances the learning and development of children.
