description: The temperature dependence of the relaxation dynamics in the bilayer thin film heterostructure composed of multiferroic BiFeO$_{3}$ (BFO) and superconducting YBa$_{2}$Cu$_{3}$O$_{7}$ (YBCO) grown on a (001) SrTiO$_{3}$ substrate is studied by a time-resolved pump-probe technique, and compared with that of pure YBCO thin film grown under the same growth conditions. The superconductivity of YBCO is found to be retained in the heterostructure. We observe a speeding up of the YBCO recombination dynamics in the superconducting state of the heterostructure, and attribute it to the presence of weak ferromagnetism at the BFO/YBCO interface as observed in magnetization data. An extension of the Rothwarf-Taylor model is used to fit the ultrafast dynamics of BFO/YBCO, that models an increased quasiparticle occupation of the ferromagnetic interfacial layer in the superconducting state of YBCO.

Effects of a scalar scaling field on quantum mechanics
Creators: name: Benioff, Paul
Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: This paper describes the effects of a complex scalar scaling field on quantum mechanics. The field origin is an extension of the gauge freedom for basis choice in gauge theories to the underlying scalar field. The extension is based on the idea that the value of a number at one space time point does not determine the value at another point. This, combined with the description of mathematical systems as structures of different types, results in the presence of separate number fields and vector spaces, both as structures, at different space time locations. Complex number structures and vector spaces at each location, are scaled by a complex space time dependent scaling factor. The effect of this scaling factor on several physical and geometric quantities has been described in other work. Here the emphasis is on quantum mechanics of one and two particles, their states and properties. Multiparticle states are also briefly described. The effect shows as a complex, nonunitary, scalar field connection on a fiber bundle description of nonrelativistic quantum mechanics. The lack of physical evidence for the presence of this field so far means that the coupling constant of this field to fermions is very small. It also means that the gradient of the field must be very small in a local region of cosmological space and time. Outside this region there are no restrictions on the field gradient.

description: We provide general inequalities that compare the surface area S(K) of a convex body K in ${\mathbb R}^n$ to the minimal, average or maximal surface area of its hyperplane or lower dimensional projections. We discuss the same questions for all the quermassintegrals of K. We examine separately the dependence of the constants on the dimension in the case where K is in some of the classical positions or K is a projection body. Our results are in the spirit of the hyperplane problem, with sections replaced by projections and volume by surface area.

description: This deliverable (entitled “D7.11 - Data Marketplace: Design and Open Specification M32”) is a follow up on the design and the specifications of the PolicyCLOUD Data Marketplace as defined in the previous version of the deliverable (i.e. the “D7.4 - Data Marketplace: Design and Open Specification”). Several updates have been introduced in the deliverable, including, among others, the final types of assets to be offered by the Data Marketplace, additional user journeys and state of the art marketplaces, whereas there are additional updates on the specifications of the Data Marketplace’s layers (especially for the Assets Storage Layer and the Assets Management Layer). Finally, some use cases of the Data Marketplace are introduced under the Overall Conceptual View Section. In essence, the Data Marketplace is a unified web-based platform consisting of two (2) core services, the front-end and the back-end services, offering its users various ready-to-use solutions. More specifically, it provides to the wider research and innovation community various assets (i.e. objects/solutions) in different domains. As a Marketplace, the final design provides information on how several users (and contributors) can interact with the PolicyCLOUD Data Marketplace in order to ingest and retrieve the respective assets, through potential user journeys that are analyzed. Moreover, the deliverable describes the different types of offered assets, since the Data Marketplace went beyond policies and tools and it stores and offers additional elements, including rich descriptions of the offered assets, algorithms, validation datasets, and in general, various outcomes of the project. To support the aforementioned functionalities, the PolicyCLOUD Data Marketplace specifications exemplify the respective layers of the Data Marketplace, the functionalities supported by each layer, the interaction points with different stakeholders, as well as the technical details that have been used for the implementation of the Data Marketplace. Finally, the document reviews the current state of the art marketplaces to identify the baseline technologies and approaches for the realization of similar marketplaces, which are compared to the corresponding specifications of the Data Marketplace.

description: We study the renormalization flow of the Higgs potential as a function of both field amplitude and energy scale. This overcomes limitations of conventional techniques that rely, e.g., on an identification of field amplitude and RG scale, or on local field expansions. Using a Higgs-Yukawa model with discrete chiral symmetry as an example, our global flows in field space clarify the origin of possible meta-stabilities, the fate of the pseudo-stable phase, and provide new information about the renormalization of the tunnel barrier. Our results confirm the relaxation of the lower bound for the Higgs mass in the presence of more general microscopic interactions (higher-dimensional operators) to a high quantitative accuracy.

description: Dairy processing sludge (DPS) is a byproduct generated in wastewater treatment plants located in dairy (milk) processing companies (waste activated sludge). DPS presents challenges in terms of its management (as biosolids) due to its high moisture content, prolonged storage required, uncontrolled nutrient loss and accumulation of certain substances in soil in the proximity of dairy companies. This study investigates the potential of hydrothermal carbonization (HTC) for recovery of nutrients in the form of solid hydrochar (biochar) produced from DPS originating from four different dairy processing companies. The HTC tests were carried out at 160 ◦C, 180 ◦C, 200 ◦C and 220 ◦C, and a residence time of 1h. The elemental properties of hydrochars (biochars), the content of primary and secondary nutrients, as well as contaminants were examined. The transformation of phosphorus in DPS during HTC was investigated. The fraction of plant available phosphorus was determined. The properties of hydrochar (biochar) were compared against the European Union Fertilizing Products Regulation. The findings of this study demonstrate that the content of nutrient in hydrochars (biochars) meet the requirements for organo-mineral fertilizer with nitrogen and phosphorus as the declared nutrients (13.9–26.7%). Further research on plant growth and field tests are needed to fully assess the agronomic potential of HTC hydrochar (biochar).

description: Professional athletes and organizations can face significant consequences as a result of injury incidents in sports. Therefore, an abundance of studies has been conducted to identify the risk factors in the hope of preventing injuries from occurring in the first place. Hamstring strain injuries (HSIs) are the most frequent injuries in Australian Football League (AFL). Many studies had shown that there are several prominent risk factors for HSIs. However, this finding cannot be identified with any consistency through assessing the risk factors at a single time point, typically the beginning of a season (e.g., in the pre-season) or more frequently throughout the season (e.g., in the pre-season, early in-season and late in-season). Nonetheless, these studies did not consider the potential variability of risk factors across the season. In light of this, it was hypothesised that risk factors may vary depending on the time of the season. This thesis aims to answer if the risk of hamstring strain injuries in Australian Football can be reduced through a better understanding of the changing risk factors over the course of the season. Despite the study, identifying HSI risk at individual-level remains a challenge. This study aims to explore whether the risk of HSI for individual players can be better understood by explaining the predictions of machine learning (ML) models. The study utilised recursive feature selection and cross-validation to provide a holistic understanding of important risk factors at different points. Subsequently, counterfactual explanations were effectively generated for players at risk of sustaining HSI. The study found that non-modifiable risk factors were primarily linked to pre-season injuries, whereas modifiable risk factors were mostly associated with early in-season injuries. Counterfactual explanations and ML models offer a novel perspective in interpreting risk and finding potential solutions. Overall, this study provides new insights into risk factors associated with HSIs at different time points, as well as offers a solution for interpreting risk at individual-level using ML models and counterfactual explanations. The findings have important implications for researchers and practitioners who seek to mitigate the risk of HSI in the future.

description: The heartland of the Khmer empire is literally crowded by magnificent monuments built in the course of many centuries. These monuments include the world-famous state-temples, such as Angkor Wat, but also many other temples and huge water reservoirs. Using Google Earth data as well as GIS data and reconstructing the ancient sky with Stellarium, we investigate here on the relationships of astronomy with orientation and topography in a systematic fashion, following the methods of modern Archaeoastronomy and strictly keeping at a bay vague or esoteric proposals put forward by many authors in the past. As a result, a very clear pattern of cardinal orientation and alignment arises, connected with the temple's symbolism and the management of power by the Khmer kings. As a bonus, the comparison with the Angkor monuments allows to put forward a explanation for the anomalous orientation of the unique two peripheral state temples of Cambodia.

description: Cell association in cellular networks is an important aspect that impacts network capacity and eventually quality of experience. The scope of this work is to investigate the different and generalized cell association (CAS) strategies for Device-to-Device (D2D) communications in a cellular network infrastructure. To realize this, we optimize D2D-based cell association by using the notion of uplink and downlink decoupling that was proven to offer significant performance gains. We propose an integer linear programming (ILP) optimization framework to achieve efficient D2D cell association that minimizes the interference caused by D2D devices onto cellular communications in the uplink as well as improve the D2D resource utilization efficiency. Simulation results based on Vodafone's LTE field trial network in a dense urban scenario highlight the performance gains and render this proposal a candidate design approach for future 5G networks.

Theories of Ritual and Greek Women’s Festivals: The Thesmophoria and the Adonia
Creators: name: McLardy, Katherine Rebecca Leigh
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: This thesis re-examines the evidence relating to two ancient Greek festivals: the Thesmophoria in honour of the goddess Demeter Thesmophoros and the Adonia in honour of the Adonis, the short-lived consort of Aphrodite. Past research has been largely preoccupied with reconstructing a general pattern for the festival; contrary to this, I argue that the festivals must be viewed in their local contexts which allows us to observe considerable variation to their structure and meaning(s). Through the application of a post-structuralist methodology, selectively enhanced with phenomenological premises, I consider both the evolution of these festivals over time and place and, crucially, the impact that these festivals would have had on the women who celebrated them.

 To this direction, I use not only the surviving literary evidence regarding these festivals but, also, epigraphic, archaeological, and iconographic evidence where possible. This allows for an additional focus on small details that indicate potential local variation as opposed to merging all of the evidence into a generalised reconstruction. I contend that it is important to recognise that rituals such as these were multifaceted and cannot be fully explained under a single paradigm; instead, an interdisciplinary approach is required in order to reconstruct and interpret these festivals in a manner which brings us closer to how they really worked within their actual historical contexts. From this perspective, my work adds to the ongoing scholarly discussion on the most appropriate theoretical framework by which to examine ancient women’s rituals.

 In addition, the theoretical model I have developed emphasises the experience of the ancient participants. Through focusing on the functions that festivals such as the Thesmophoria and the Adonia had in their lives, I hope to shed more light on their importance and enduring popularity amongst ancient Greek women. Important components of my model are a focus on communitas, performativity and phenomenological viewpoints in order to produce a more accurate and well-rounded reconstruction of these festivals. It is essential to note that this model is not designed to shape the ancient evidence into a consistent account that satisfies the modern reader, but to highlight the many, sometimes contradictory, aspects of these festivals in a more realistic manner.

description: We consider various notions of strains; quantitative measures for the deviation of a linear transformation from an isometry. The main approach, which is motivated by physical applications and follows the work of Patrizio Neff and co-workers , is to select a Riemannian metric on $\text{GL}_n$, and use its induced geodesic distance to measure the distance of a linear transformation from the set of isometries. We give a short geometric derivation of the formula for the strain measure for the case where the metric is left-$\text{GL}_n$-invariant and right-$\text{O}_n$-invariant. We proceed to investigate alternative distance functions on $\text{GL}_n$, and the properties of their induced strain measures. We start by analyzing Euclidean distances, both intrinsic and extrinsic. Next, we prove that there are no bi-invariant distances on $\text{GL}_n$. Lastly, we investigate strain measures induced by inverse-invariant distances.

For the first time, we have measured this relation via weak-lensing analysis down to $M_{500,WL} =3.5 \times 10^{13}\,M_\odot$. This allows us to investigate whether the slope of the $L_K-M$ relation is different for groups and clusters, as seen in other works. The clusters in our sample span a wide range in mass, $M_{500,WL} =0.35-12.10 \times 10^{14}\,M_\odot$, at $0

description: Understanding and exploiting the remarkable optical and electronic properties of phosphorene require mass production methods that avoid chemical degradation. While solution-based strategies have been developed for scalable exfoliation of black phosphorus, these techniques have thus far employed anhydrous organic solvents in an effort to minimize exposure to known oxidants, but at the cost of limited exfoliation yield and flake size distribution. Here, we present an alternative phosphorene production method based on surfactant-assisted exfoliation and post-processing of black phosphorus in deoxygenated water. From comprehensive microscopic and spectroscopic analysis, this approach is shown to yield phosphorene dispersions that are stable, highly concentrated, and comparable to micromechanically exfoliated phosphorene in structure and chemistry. Due to the high exfoliation efficiency of this process, the resulting phosphorene flakes are thinner than anhydrous organic solvent dispersions, thus allowing the observation of layer-dependent photoluminescence down to the monolayer limit. Furthermore, to demonstrate preservation of electronic properties following solution processing, the aqueous-exfoliated phosphorene flakes are employed in field-effect transistors with high drive currents and current modulation ratios. Overall, this method enables the isolation and mass production of few-layer phosphorene, which will accelerate ongoing efforts to realize a diverse range of phosphorene-based applications.

description: Many experiments have shown the detection of spin-currents driven by radio-frequency spin pumping from yttrium iron garnet (YIG), by making use of the inverse spin-Hall effect, which is present in materials with strong spin-orbit coupling, such as Pt. Here we show that it is also possible to directly detect the resonance-driven spin-current using Au/permalloy (Py, Ni$_{80}$Fe$_{20}$) devices, where Py is used as a detector for the spins pumped across the YIG/Au interface. This detection mechanism is equivalent to the spin-current detection in metallic non-local spin-valve devices. By finite element modeling we compare the pumped spin-current from a reference Pt strip with the detected signals from the Au/Py devices. We find that for one series of Au/Py devices the calculated spin pumping signals mostly match the measurements, within 20%, whereas for a second series of devices additional signals are present which are up to a factor 10 higher than the calculated signals from spin pumping. We also identify contributions from thermoelectric effects caused by the resonant (spin-related) and non-resonant heating of the YIG. Thermocouples are used to investigate the presence of these thermal effects and to quantify the magnitude of the Spin-(dependent-)Seebeck effect. Several additional features are observed, which are also discussed.

description: The sunspot number is analyzed by using detailed sunspot data, including aspects of observability, sunspot sizes, and proper identification of sunspot groups as discrete entities of the solar activity. The tests show that besides the subjective factors there are also objective causes of the ambiguities in the series of sunspot numbers. To introduce an alternative activity measure the physical meaning of the sunspot number has to be reconsidered. It contains two components whose numbers are governed by different physical mechanisms, this is one source of the ambiguity. This article suggests an activity index, which is the amount of emerged magnetic flux. The only long-term proxy measure is the detailed sunspot area dataset with proper calibration to the magnetic flux amount. The Debrecen sunspot databases provide an appropriate source for the establishment of the suggested activity index.

description: Generalizing the Randall-Sundrum scenario to higher dimensions with nested warpings has been shown to avoid the constraints besetting the former. In the first paper of this series [JHEP 1509 (2015) 202], the Standard Model gauge and fermion fields were extended into such a six-dimensional bulk and the construction was shown to have several interesting and welcome features. In this paper, we discuss the electroweak symmetry breaking, presenting a novel Higgs localization mechanism that leads to interesting phenomenology in the Higgs sector. Localizing the Higgs modifies the $Z_μ$ and $W_μ$ boson wavefunctions, which leads to tree level changes in the oblique parameters. Using these as well as the correction to low-energy four-Fermi operators, we derive the constraints on our model and also discuss the gauge coupling evolution therein. Amusingly, the model can naturally incorporate a Higgs resonance in the 700--800 GeV range.

description: The transition from the dominant value chain models based on "Take, Make, Use, and Dispose" to the Circular Economy (CE) is gaining global traction as a sustainable development approach. With a growing global population surpassing 7.7 billion people, the need for sustainable practices that safeguard resources and protect vulnerable communities is becoming increasingly urgent. This article presents a systematic literature review conducted to assess to which extent researchers are addressing the adaptation of value chain models to the emerging concepts of CE, using a structured methodology that involved three stages: definition of the research focus, search for relevant literature, and reporting the results, being the goal to provide a comprehensive and unbiased analysis. Based on a final working sample of 159 articles extracted from Scopus and Web of Science Core Collection, we discover there is a higher interest from the scientific community to analyze traditional value chain models and relate them with the new concepts introduced by circular economies, revealing an active engagement of the scientific community in addressing the challenges posed by consumers and policy regulators to promote a sustainable society. Furthermore, the results suggest a rising trend of the combination of traditional value chain models with strategies and objectives of the CE practices.

description: We report the results of VERA multi-epoch VLBI 22 GHz water maser observations of S255IR-SMA1, a massive young stellar object located in the S255 star forming region. By annual parallax the source distance was measured as D = 1.78 +-0.12 kpc and the source systemic motion was (u alpha cos d, u d) = (-0.13 +- 0.20, -0.06 +- 0.27) mas yr-1. Masers appear to trace a U-shaped bow shock whose morphology and proper motions are well reproduced by a jet-driven outflow model with a jet radius of about 6 AU. The maser data, in the context of other works in the literature, reveal ejections from S255IR-SMA1 to be episodic, operating on timescales of ~1000 years.

Impact on floating membranes

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: When impacted by a rigid object, a thin elastic membrane with negligible bending rigidity floating on a liquid pool deforms. Two axisymmetric waves radiating from the impact point propagate. In the first place, a longitudinal wave front -- associated with in-plane deformation of the membrane and traveling at constant speed -- separates an outward stress free domain with a stretched but flat domain. Then, in the stretched domain a dispersive transverse wave travels at a wave speed that depends on the local stretching rate. We study the dynamics of this fluid-body system and we show that the wave dynamics is similar to the capillary waves that propagate at a liquid-gas interface but with a surface tension coefficient that depends on impact speed. We emphasize the role of the stretching in the membrane in the wave dynamics but also in the development of a buckling instability that give rise to radial wrinkles.

description: Thermal observations of the Pluto-Charon system acquired by the Herschel Space Observatory in February 2012 are presented. They consist of photometric measurements with the PACS and SPIRE instruments (nine visits to the Pluto system each), covering six wavelengths from 70 to 500 $μ$m altogether. The thermal light curve of Pluto-Charon is observed in all filters, albeit more marginally at 160 and especially 500 $μ$m. Putting these data into the context of older ISO, Spitzer and ground-based observations indicates that the brightness temperature (T$_B$) of the system (rescaled to a common heliocentric distance) drastically decreases with increasing wavelength, from $\sim$53 K at 20 $μ$m to $\sim$35 K at 500 $μ$m, and perhaps ever less at longer wavelengths. Considering a variety of diurnal and/or seasonal thermophysical models, we show that T$_B$ values of 35 K are lower than any expected temperature for the dayside surface or subsurface of Pluto and Charon, implying a low surface emissivity. Based on multiterrain modeling, we infer a spectral emissivity that decreases steadily from 1 at 20-25 $μ$m to $\sim$0.7 at 500~$μ$m. This kind of behavior is usually not observed in asteroids (when proper allowance is made for subsurface sounding), but is found in several icy surfaces of the solar system. We tentatively identify that a combination of a strong dielectric constant and a considerable surface material transparency (typical penetration depth $\sim$1 cm) is responsible for the effect. Our results have implications for the interpretation of the temperature measurements by REX/New Horizons at 4.2 cm wavelength.

Books for Australian Boys: Manipulating Genre in Contemporary Young Adult Fiction
Creators: name: Potter, Troy
Publisher: name: Monash University

Subjects: subject: 200599 Literary Studies not elsewhere classified

description: This thesis examines how genre is used and exploited to construct a range of masculinities in a representative selection of contemporary Australian Young Adult (YA) fiction. The production and labelling of “books for boys” in the field of children’s and YA literature has seen a resurgence in Australia in recent years, perhaps as a response to contemporary concerns about a “crisis” in masculinity and masculine self-perception. Inherent to the categorisation of these books is an essentialist understanding of gender and masculinity, particularly in relation to boys’ behaviour and interests.

 Genre, as well as gender, is vital to the production of books for boys. Surveys of Australian adolescent reading practices have indicated that boys show a preference for particular modes of fiction. “Genre” suggests a representative set of stylistic devices and formulaic narrative traits employed within a particular text. Yet genre is also a reciprocal dynamic, providing structure for the production and interpretation of meaning, both within a text and between the reader and his/her cultural context. Moreover, books for boys as marketed literary artefacts perpetuate the perception that masculinity is in a troubled state. Genre thus functions as a means to respond to and shape contemporary concerns about what it means to be male.

 Adopting this generic approach, I analyse how individual texts and genres value and promote particular masculine characteristics, and consider how fictive masculinities position implied male readers within gendered paradigms. I argue that books for boys, while presenting revised masculinities, nevertheless support and validate essentialist and hierarchical constructions of gendered identity.

description: Masses adjacent to the classical waiting-point nuclide 130Cd have been measured by using the Penning- trap spectrometer ISOLTRAP at ISOLDE/CERN. We find a significant deviation of over 400 keV from earlier values evaluated by using nuclear beta-decay data. The new measurements show the reduction of the N = 82 shell gap below the doubly magic 132Sn. The nucleosynthesis associated with the ejected wind from type-II supernovae as well as from compact object binary mergers is studied, by using state-of-the-art hydrodynamic simulations. We find a consistent and direct impact of the newly measured masses on the calculated abundances in the A = 128 - 132 region and a reduction of the uncertainties from the precision mass input data.

description: We present new identifications of five red giant stars in the Galactic halo with chemical abundance patterns that indicate they originally formed in globular clusters. Using data from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) Survey available through Sloan Digital Sky Survey Data Release 12 (DR12), we first identify likely halo giants, and then search those for the well-known chemical tags associated with globular clusters, specifically enrichment in nitrogen and aluminum. We find that 2% of the halo giants in our sample have this chemical signature, in agreement with previous results. Following the interpretation in our previous work on this topic, this would imply that at least 13% of halo stars originally formed in globular clusters. Recent developments in the theoretical understanding of globular cluster formation raise questions about that interpretation, and we concede the possibility that these migrants represent a small fraction of the halo field. There are roughly as many stars with the chemical tags of globular clusters in the halo field as there are in globular clusters, whether or not they are accompanied by a much larger chemically untaggable population of former globular cluster stars.

Strange Matter: a state before black hole

description: Normal baryonic matter inside an evolved massive star can be intensely compressed by gravity after a supernova. General relativity predicts formation of a black hole if the core material is compressed into a singularity, but the real state of such compressed baryonic matter (CBM) before an event horizon of black hole appears is not yet well understood because of the non-perturbative nature of the fundamental strong interaction. Certainly, the rump left behind after a supernova explosion could manifest as a pulsar if its mass is less than the unknown maximum mass, $M_{\rm max}$. It is conjectured that pulsar-like compact stars are made of strange matter (i.e., with 3-flavour symmetry), where quarks are still localized as in the case of nuclear matter. In principle, different manifestations of pulsar-like objects could be explained in the regime of this conjecture. Besides compact stars, strange matter could also be manifested in the form of cosmic rays and even dark matter.

description: In order to improve the short-term stability of trapped-ion optical clocks, we are developing a frequency standard based on ${}^{115}$In${}^+$ / ${}^{172}$Yb${}^+$ Coulomb crystals. For this purpose, we have developed scalable segmented Paul traps which allow a high level of control for multiple ion ensembles. In this article, we detail on our recent results regarding the reduction of the leading sources of frequency uncertainty introduced by the ion trap: 2nd-order Doppler shifts due to micromotion and the heating of secular motion, as well as the black-body radiation shift due to warming of the trap. We show that the fractional frequency uncertainty due to each of these effects can be reduced to well below $10^{-19}$.

Markov Selection and $W$-strong Feller for 3D Stochastic Primitive Equations

Publisher: name: arXiv
Year: 2016
Subjects: subject: Probability (math.PR)

description: This paper studies some analytical properties of weak solutions of 3D stochastic primitive equations with periodic boundary conditions. The martingale problem associated to this model is shown to have a family of solutions satisfying the Markov property, which is achieved by means of an abstract selection principle. The Markov property is crucial to extend the regularity of the transition semigroup from small times to arbitrary times. Thus, under a regular additive noise, every Markov solution is shown to have a property of continuous dependence on initial conditions, which follows from employing the weak-strong uniqueness principle and the Bismut-Elworthy-Li formula.
Two-dimensional phosphorus carbide: Competition between sp2 and sp3 bonding

description: We propose previously unknown allotropes of phosphorus carbide (PC) in the stable shape of an atomically thin layer. Different stable geometries, which result from the competition between sp2 bonding found in graphitic C and sp3 bonding found in black P, may be mapped onto 2D tiling patterns that simplify categorizing of the structures. Depending on the category, we identify 2D-PC structures that can be metallic, semi-metallic with an anisotropic Dirac cone, or direct-gap semiconductors with their gap tunable by in-layer strain.

description: Ferramentas desenvolvidas para ensinar Matemática, ou Mathematical Cognitve Tools fazem uso de representações visuais de matemática, conhecidas na literatura como VMR – Visual Mathematical Representations. Por exemplo: gráficos, padrões visuais, estruturas geométricas, diagramas e representações de conceitos abstratos, tais como frações, operações e contagem são utilizadas em diferentes disciplinas com diferentes níveis de complexidade. VMRs apresentam propriedades cuja manipulação pode fazer perceber contiguidade entre essas e as propriedades dos conceitos metaforicamente representados. As modalidades de interação, neste contexto, são vistas como mediadora entre usuários e VMRs; sendo utilizadas para apoiar atividades de organização, comparação, modelização, visualização e interpretação – envolvidas em atividades de investigação e exploração de objetos matemáticos. O objetivo dessa palestra é, portanto, colocar o tema em pauta no I Encontro Regional de Matemática Aplicada e Computacional do Nordeste, buscando evidenciar mais interfaces de aprendizagem entre Matemática e Computação.
