description: In the tasks of environmental monitoring is of great importance to have compact and portable systems able to identify environmental contaminants that facilitate tasks related to waste management and environmental restoration. In this paper, a prototype sensor is described to identify contaminants in the environment. This prototype is made with an array of tin oxide SnO2 gas sensors used to identify chemical vapors, a step of data acquisition implemented with ARM (Advanced RISC Machine) low-cost platform (Arduino) and a neural network able to identify environmental contaminants automatically. The neural network is used to identify the composition of contaminant census. In the computer system, the heavy computational load is presented only in the training process, once the neural network has been trained, the operation is to spread the data across the network with a much lighter computational load, which consists mainly of a vector-matrix multiplication and a search table that holds the activation function to quickly identify unknown samples.

description: In recent years, a lot of effort has been devoted to the quest for experimental realizations of Kitaev interactions in spin systems. Recently, many materials have been synthesized which seem to realize extended Kitaev models, where Kitaev interactions are supplemented by Heisenberg and other bond dependent terms. The crystal and electronic structure of these materials renders the determination of a minimal model a non trivial pursuit. In this work, we will concentrate on one of these particular materials, $α$-Li$_2$IrO$_3$, for which various minimal models have been proposed. Employing large scale Monte Carlo simulations we show how the number of prospective models can be reduced. We study in detail six models with different range of the interactions, and show how only two of those reproduce the most recent experimental results for this material. We obtain two possible minimal models, one of them with nearest neighbour interactions, while the other includes interactions up to third neighbours. Furthermore, we show that strong bond anisotropies and further neighbour interactions are crucial to stabilize the tilted counterotating spirals found in $α$-Li$_2$IrO$_3$. We further clarify the picture, and distinguish these two models by studying the magnetization processes. We predict the magnetization behaviour of these models, and propose future experimental directions.

Targeting Language Ownership and Awareness with Authentic Uses of English

Year: 2019

description: The present paper describes a 12-week content-based course implemented with a class of secondary school students in Italy that aimed to enhance the levels of language ownership and awareness via authentic uses of English. The themes of exclusion and exile – viewed from historical and contemporary standpoints – served as a springboard for class discussions and debates, and inspired the development of collaborative, multimodal final projects shared on Write4Change, an international virtual writing community. After reporting on language attitude and ownership data collected with an entry questionnaire that informed the course design, this paper describes the four phases of the course in detail and presents an overview of ways in which authenticity was embedded within the course. Favorable student responses to the course and its successful implementation, notwithstanding contextual constraints such as limited access to technology, make replication of this course in other learning settings both feasible and worthwhile.

Autobiographical Narrative and Intercultural Awareness

Year: 2019

description: The currency of intercultural education has risen worldwide in response to increased diversity within societies resulting from migration and global flows of populations. As intercultural education becomes a core responsibility of schooling, the attention to developing students’ intercultural capabilities grows even faster. The school and all the educational agencies must find the most suitable tools to adequately address the complex multiculturalism of the third millennium, so to promote the students’ ability to understand one another across and beyond all types of cultural barriers. This paper offers a reflexive analysis of the efficacy of using autobiographical narratives for enhancing students’ intercultural awareness. Autobiographical narratives have a productive potential as a strategy for stimulating reflexivity about cultural identities and intercultural relations. The Autobiography of Intercultural Encounters (AIE), published by the Council of Europe (2009), is proposed and analyzed as a framework that can help students reflect critically on specific intercultural encounters and promote intercultural communication situations. ‘Intercultural communication’ is today a model that allows all children and young people to recognize and being aware of each other’s identity, as it is oriented towards fostering interaction, dialogue, mutual recognition and enrichment of any individual, in respect of the different identities of the other; it is an approach that offers a forward-looking model for managing cultural and language diversity.

Broadening the Scope of Language Education: Mediation, Plurilingualism, and Collaborative Learning: the CEFR Companion Volume

description: The CEFR’s action-oriented approach, including its concept of the user/learner as a social agent mobilising a plurilingual repertoire, represents a significant development from the communicative approach. The CEFR moves beyond the traditional four skills (spoken and written reception and production) to also include interaction and mediation, opening to a complex vision of the situated and integrated nature of language learning and language use. Advances in research highlight the need to overcome a vision of languages as stable, pure objects existing outside their speakers/users and a reductive view of learning as an internal cognitive process, meant to prepare for later real-life use. These theoretical advances have been flanked by bottom up developments bringing a more dynamic vision of language education that engages more meaningfully with the principles of the CEFR. The time was therefore ripe to complete the CEFR descriptive apparatus with new descriptors for mediation and plurilingual/pluricultural competence. This article outlines the conceptualisation, development and validation of these descriptors and their publication in the CEFR Companion Volume (2018), alongside a text clarifying the paradigm shift in language education implied by the notion of the user/learner as a plurilingual/pluricultural social agent. The goal is to promote quality, inclusive education for all, and in particular to further the recognition and valorisation of linguistic and cultural diversity and the promotion of plurilingual interculturality.

description: The development in the area of wireless communication, mobile and embedded computing leads to significant changes in the application of devices. Over the last years, embedded devices were brought into the consumer area creating the Internet of Things. Furthermore, industrial applications increasingly rely on communication through trust boundaries. Networking is cheap and easily applicable while providing the possibility to make everyday life more easy and comfortable and industry more efficient and less time-consuming. One of the crucial parts of this interconnected world is sound and secure authentication of entities. Only entities with valid authorisation should be enabled to act on a resource according to an access control scheme. An overview of challenges and practices of authentication is provided in this work, with a special focus on context information as part of security solutions. It can be used for authentication and security solutions in industrial applications. Additional information about events in networks can aid intrusion detection, especially in combination with security information and event management systems. Finally, an authentication and access control approach, based on context information and - depending on the scenario - multiple factors is presented. The combination of multiple factors with context information makes it secure and at the same time case adaptive, so that the effort always matches, but never exceeds, the security demand. This is a common issue of standard cyber security, entities having to obey strict, inflexible and unhandy policies. This approach has been implemented exemplary based on RADIUS. Different scenarios were considered, showing that this approach is capable of providing flexible and scalable security for authentication processes.

The warm Gaseous Disk and the Anisotropic Circumgalactic Medium of the Milky Way

description: The warm ($\log~T\approx5$) gas is an important gaseous component in the galaxy baryonic cycle. We built a 2-dimension disk-CGM model to study the warm gas distribution of the Milky Way (MW) using the absorption line surveys of Si IV and O VI. In this model, the disk component of both ions has the same density profile ($n(r, z)=n_0\exp(-|z|/z_0)\exp(-r/r_0)$) with a scale height of $z_0=2.6\pm0.4\rm~kpc$ and a scale length of $r_0=6.1\pm1.2\rm~kpc$. For this disk component, we calculate the warm gas mass of $\log(M/M_\odot)=(7.6\pm0.2)-\log\frac{Z}{Z_\odot}$. The similar disk density profiles and total masses of Si IV and O VI-bearing gas set constraints on the ionization mechanisms. We suggest that the warm gas disk might be dominated by the Galactic fountain mechanism, which ejects and recycles gas to set both the scale height and the scale length of the warm gas disk. The CGM component in our model has a dependence on Galactic latitude with a higher column density along the direction perpendicular to the Galactic plane ($b=90^\circ$) than the column density along the radial direction ($b=0^\circ$). The column density difference between these two directions is $0.82\pm0.32\rm~dex$ at $6.3σ$ for both ions. This difference may be due to the enrichment of Galactic feedback to the entire CGM, or an additional interaction layer between the warm gas disk and the CGM; existing data cannot distinguish between these two scenarios. If this higher column density at $b=90^\circ$ is for the entire CGM, the total warm CGM mass is $\log(M/M_\odot)\approx(9.5-9.8)-\log\frac{Z}{0.5Z_\odot}$ within the MW virial radius of $250\rm~kpc$.

These problems can be avoided by utilizing optical technologies. As a replacement for the standard low-noise preamplifier, we have implemented a new transduction principle that upconverts an MR signal to the optical domain and imaged a phantom in a clinical 3 T scanner with signal-to-noise comparable to classical induction detection.

description: This article proposes that superconductivity in the ferromagnetic state of ZrZn$_2$ is stabilized by an exchange-type interaction between the magnetic moments of triplet-state Cooper pairs and the ferromagnetic magnetization density. This explains why superconductivity occurs in the ferromagnetic state only, and why it persists deep into the ferromagnetic state. The model of this article also yields a particular order parameter symmetry, which is a prediction that can be checked experimentally.

Language awareness in a comprehensive approach to language teaching and learning
Creators: name: Kelly, Michael
Publisher: name: Journal of e-Learning and Knowledge Society
Year: 2019

description: The importance of language awareness has been highlighted in the most recent policy document of the European Commission, in response to the disappointing progress of European citizens towards the aim of proficiency in a first language and in two other languages. Language awareness has a long history and many meanings and is well placed to draw together a range of strategies aiming to improve language learning and teaching in European education. This paper argues that the broad scope of language awareness provides both opportunities and challenges for educators and policy makers. It examines the experience of language awareness in the UK and suggests lessons that might be learned from its achievements and from the challenges it encountered. In particular, targeted initiatives will be required to explore the barriers that remain to be overcome, new research will be required, along with the development of tools, strategies and collaborations to extend language awareness into areas where it can bring fresh benefits.

description: Large spin systems as given by magnetic macromolecules or two-dimensional spin arrays rule out an exact diagonalization of the Hamiltonian. Nevertheless, it is possible to derive upper and lower bounds of the minimal energies, i.e. the smallest energies for a given total spin S. The energy bounds are derived under additional assumptions on the topology of the coupling between the spins. The upper bound follows from "n-cyclicity", which roughly means that the graph of interactions can be wrapped round a ring with n vertices. The lower bound improves earlier results and follows from "n-homogeneity", i.e. from the assumption that the set of spins can be decomposed into n subsets where the interactions inside and between spins of different subsets fulfill certain homogeneity conditions. Many Heisenberg spin systems comply with both concepts such that both bounds are available. By investigating small systems which can be numerically diagonalized we find that the upper bounds are considerably closer to the true minimal energies than the lower ones.

Enhancing Language Awareness and Competence-building through a Fusion of Phenomenon-based Learning and Content and Language Integration
Creators: name: Marsh, David

name: Escárzaga Morales, Mariana
Publisher: name: Journal of e-Learning and Knowledge Society
Year: 2019

description: This article describes how the fusion of two innovative approaches in education can provide alternative pathways to the learning of academic subjects, including languages. Content and Language Integrated Learning (CLIL) and Phenomenon-based Learning (PhBL) are combined to achieve intended learning outcomes which includes language awareness, attitude change towards language learning, and transversal subject learning. Enabling a form of pragmatic social constructivism, both CLIL and PhBL are heavily identified with types of integrative educational practices common to Finland. Following an introduction to each practice, the article describes the use of this fusion approach with high school students in Mexico where the level of additional language competence is generally low. Acknowledging that there are rarely educational models that can be exported from one country to another, it is argued that the fusion of CLIL and PhBL provides a blueprint that can enable educational innovation to flourish in different contexts.

description: The contribution focuses on online interaction as a new important dimension in the linguistic competence and repertoire of a learner, as highlighted by the Companion Volume to the CEFR. Starting from a quick overview on the theoretical framework related to the main features of the linguistic variety used in digital and multimodal environments and social networks, the paper will focus on the descriptors of online interaction presented in the Companion, referring to the initial consultation process and then to a pilot project carried out by the Italian Ministry of Education in cooperation with INDIRE, involving a school network all over Italy. Some comments from the teachers involved in the projects will be reported and discussed and in particular, an example of project carried out in one of the schools will be highlighted. As a general conclusion, experimenting the descriptors of online interaction turned out to be a very effective way to reflect and become aware of the importance of digital literacy and online communication and interaction in a foreign language, for both teachers and students.

Subjects: subject: Banach algebras
subject: Group algebras

description: The primary purpose of the research presented in this thesis is to investigate the extent to which amenability in Banach algebras is reliant on amenability in locally compact groups. One of the first results proven on amenability in Banach algebras was the equivalence of the amenability of a locally compact group G with the amenability of its group algebra L¹( G). Other instances of amenability in Banach algebras can then be demonstrated by the use of certain constructions which preserve amenability.

description: Until the last few decades, investigations of stellar interiors had been restricted to theoretical studies only constrained by observations of their global properties and external characteristics. However, in the last thirty years the field has been revolutionized by the ability to perform seismic investigations of stellar interiors. This revolution begun with the Sun, where helioseismology has been yielding information competing with what can be inferred about the Earth's interior from geoseismology. The last two decades have witnessed the advent of asteroseismology of solar-like stars, thanks to a dramatic development of new observing facilities providing the first reliable results on the interiors of distant stars. The coming years will see a huge development in this field. In this review we focus on solar-type stars, i.e., cool main-sequence stars where oscillations are stochastically excited by surface convection. After a short introduction and a historical overview of the discipline, we review the observational techniques generally used, and we describe the theory behind stellar oscillations in cool main-sequence stars. We continue with a complete description of the normal mode analyses through which it is possible to extract the physical information about the structure and dynamics of the stars. We then summarize the lessons that we have learned and discuss unsolved issues and questions that are still unanswered.

description: The discovery of extended TeV emission around the Geminga and PSR B0656+14 pulsars, with properties consistent with free particle propagation in the interstellar medium (ISM), has sparked considerable discussion on the possible presence of such halos in other systems. Here we make an assessment of the current TeV source population associated with energetic pulsars, in terms of size and estimated energy density. Based on two alternative estimators we conclude that a large majority of the known TeV sources have emission originating in the zone energetically and dynamically dominated by the pulsar (i.e. the pulsar wind nebula), rather than from a halo of particles diffusing in to the ISM. Furthermore, whilst the number of established halos will surely increase in the future, we find that it is unlikely that such halos contribute significantly to the total TeV $γ$-ray luminosity from electrons accelerated in PWN.

description: Pouring is the second most frequently executed motion in cooking scenarios. In this work, we present our system of accurate pouring that generates the angular velocities of the source container using recurrent neural networks. We collected demonstrations of human pouring water. We made a physical system on which the velocities of the source container were generated at each time step and executed by a motor. We tested our system on pouring water from containers that are not used for training and achieved an error of as low as 4 milliliters. We also used the system to pour oil and syrup. The accuracy achieved with oil is slightly lower than but comparable with that of water.

description: A theoretical scheme for the analysis of experimental data on IR spectroscopy for a quantum particle in a double well potential (DWP) is suggested. The analysis is based on the trigonometric DWP for which the exact analytic solution of the Schrödinger equation is available. The corresponding energy levels along with their wave functions are expressed via special functions implemented in {\sl {Mathematica}} (spheroidal function and its spectrum of eigenvalues). As a result trigonometric DWP makes the calculation of the energy levels an extremely easy procedure. It contains three parameters allowing one to model the most important characteristics of DWP (barrier height and the distance between the minima of the potential) along with the required asymmetry. Our approach provides an accurate calculation of the energy spectrum for hydrogen bonds in chromous acid (CrOOH) and potassium dihydrogen phosphate (${\rm{KH_2PO_4}}$) along with their polarizability in agreement with available experimental data.

Dynamic Hubbard Model

description: The Hubbard on-site repulsion $U$ between opposite spin electrons on the same atomic orbital is widely regarded to be the most important source of electronic correlation in solids. Here we extend the Hubbard model to account for the fact that the experimentally measured atomic $U$ is different from the one obtained by calculation of the atomic Coulomb integral. The resulting model describes quasiparticles that become increasingly dressed as the number of electrons in the band increases. Superconductivity can result in this model through quasiparticle undressing. Various signatures of this physics in spectroscopies in the normal and superconducting states are discussed. A novel effect in the normal state is predicted to be electroluminescence at the sample-positive counterelectrode boundary.

description: We investigate a model in which galactic nuclei form via the coalescence of pre-existing stellar systems containing supermassive black holes. Merger simulations are carried out using N-body algorithms that can follow the formation and decay of a black-hole binary and its effect on the surrounding stars down to sub-parsec scales. Our initial stellar systems have steep central density cusps similar to those in low-luminosity elliptical galaxies. Formation of a black-hole binary transfers energy to the stars and lowers the central density; continued decay of the binary creates a ~1/r density cusp similar to those observed in bright elliptical galaxies, with a break radius that extends well beyond the sphere of gravitational influence of the black holes. The decay of the black hole binary is followed over a factor of ~20 in separation after formation of a hard binary, considerably farther than in previous simulations. We see almost no dependence of the binary's decay rate on number of particles in the simulation, contrary to earlier studies in which a lower initial density of stars led to a more rapid depletion of the binary's loss cone. We nevertheless argue that the decay of a black hole binary in a real galaxy would be expected to stall at separations of 0.01-1 pc unless some additional mechanism is able to extract energy from the binary. Our results support a picture in which the observed dependence of nuclear cusp slope on galaxy luminosity is a consequence of galaxy interactions. We also discuss the implications of our results for the survivability of dark-matter cusps.

Vision-to-Language Tasks Based on Attributes and Attention Mechanism

description: Vision-to-language tasks aim to integrate computer vision and natural language processing together, which has attracted the attention of many researchers. For typical approaches, they encode image into feature representations and decode it into natural language sentences. While they neglect high-level semantic concepts and subtle relationships between image regions and natural language elements. To make full use of these information, this paper attempt to exploit the text guided attention and semantic-guided attention (SA) to find the more correlated spatial information and reduce the semantic gap between vision and language. Our method includes two level attention networks. One is the text-guided attention network which is used to select the text-related regions. The other is SA network which is used to highlight the concept-related regions and the region-related concepts. At last, all these information are incorporated to generate captions or answers. Practically, image captioning and visual question answering experiments have been carried out, and the experimental results have shown the excellent performance of the proposed approach.

description: The solution to the impact-parameter dependent Balitsky-Kovchegov equation with the collinearly improved kernel is studied in detail. The solution does not present the phenomenon of Coulomb tails at large impact parameters that have affected previous studies. The origin of this behaviour is explored numerically. It is found to be linked to the fact that this kernel suppresses large daughter dipoles. Solutions based on a physics motivated form of the initial condition are used to compute predictions for structure functions of the proton and the exclusive photo- and electroproduction of vector mesons. A reasonable agreement is found when comparing to HERA and LHC data.

description: We have obtained empirical laws for the variation of the Earth parameters with geologic time that are in agreement with coral fossil data obtained by Wells and Runcorn. Our model predicts that the day is lengthening at a rate of 2 ms/century at the present time. The length of the day when the Earth was formed is found to be 6 hours and the synodic month to be 56 days. The angular momentum of the Earth-Moon system is found to be increasing with time. The origin of the presently observed acceleration of the Moon is explained. It is predicted that the Moon is approaching the Earth at a present rate of 1.5 cm/year and with an acceleration of 20.6 arc sec/cy^2. It is shown that the Moon has never been close to the Earth in last 4.5 million years.

description: The magnetization of an ensemble of isolated lead grains of sizes ranging from below 6 nm to 1000 nm is measured. A sharp disappearance of Meissner effect with lowering of the grain size is observed for the smaller grains. This is a direct observation by magnetization measurement of the occurrence of a critical particle size for superconductivity, which is consistent with Anderson's criterion.
