description: Electronic textiles (e-textiles) are undergoing rapid technological advancements to attain e-textiles that look and feel like conventional textile fabrics. Research seeks to develop highly functionalized textile-based sensors, actuators, and energy storage devices that integrate seamlessly with current textile technologies. Presently, developments are limited by either low electrical performance, or high cost and complex construction. Additionally, negotiating the balance between high performing e-textiles and environmentally benign production is a challenge. In this report, green synthesized silver nanoparticles (AgNPs) are composited with the conjugated polymer, polypyrrole (Ppy), to create a low-cost conductive textile fabric. A Plackett–Burman design of experiment was used to optimize lime peel extract (LPE) mediated reduction for the synthesis of AgNPs. The results of this optimization process revealed silver nitrate concentration to be a significant factor in both size and UV-vis absorption maxima of the LPE-synthesized AgNPs, and reaction temperature also affecting UV-vis absorption maxima. The resultant optimized AgNPs were consistent in size (40–80 nm) and dispersity (PDI = 0.250). The LPE-synthesized AgNPs are used to form a AgNP-Ppy nanocomposite with a linen textile to produce an e-textile with low electrical resistance (37 Ω).

description: The staged increase of the LHC beam energy provides a new class of interesting observables, namely ratios and double ratios of cross sections of various hard processes. The large degree of correlation of theoretical systematics in the cross section calculations at different energies leads to highly precise predictions for such ratios. We present in this letter few examples of such ratios, and discuss their possible implications, both in terms of opportunities for precision measurements and in terms of sensitivity to Beyond the Standard Model dynamics.

description: A recent survey of a large sample of Galactic intermediate-mass (>3 Msun) asymptotic giant branch (AGB) stars shows that they exhibit large overabundances of rubidium (Rb) up to 100--1000 times solar. These observations set constraints on our theoretical notion of the slow neutron capture process (s process) that occurs inside intermediate-mass AGB stars. Lithium (Li) abundances are also reported for these stars. In intermediate-mass AGB stars, Li can be produced by proton captures occuring at the base of the convective envelope. For this reason the observations of Rb, Zr, and Li set complementary constraints on different processes occurring in the same stars. We present predictions for the abundances of Rb, Zr, and Li as computed for the first time simultaneously in intermediate-mass AGB star models and compare them to the current observational constraints. We find that the Rb abundance increases with increasing stellar mass, as is inferred from observations but we are unable to match the highest observed [Rb/Fe] abundances. Inclusion of a partial mixing zone (PMZ) to activate the 13C(a,n)16O reaction as an additional neutron source yields significant enhancements in the Rb abundance. However this leads to Zr abundances that exceed the upper limits of the current observational constraints. If the third dredge-up (TDU) efficiency remains as high during the final stages of AGB evolution as during the earlier stages, we can match the lowest values of the observed Rb abundance range. We predict large variations in the Li abundance, which are observed. Finally, the predicted Rb production increases with decreasing metallicity, in qualitative agreement with observations of Magellanic Cloud AGB stars. However stellar models of Z=0.008 and Z=0.004 intermediate-mass AGB stars do not produce enough Rb to match the observed abundances.

description: Here, we report the efficient one-pot removal of heavy metal ions and pharmaceuticals using xerogel, activated carbon and gravel. The simplest xerogel from tetramethyl orthosilicate showed ∼ twice the adsorption capacity of activated carbon derived from banana peels at 600 °C and far greater (x 35) than quartz pellets of diameter ∼300 μm. Functional groups present in both xerogel and activated carbon greatly enhanced the adsorption process. The combination of the three adsorbents resulted in the removal of > 95% of heavy metal ions and pharmaceuticals from water. The data fitted well in linear equations of Langmuir and Freundlich adsorption isotherms, and pseudo-first-order and pseudo-second-order kinetics, an indication for physisorption, chemisorption, adsorption and desorption processes during pollutant capture by the adsorbents.

description: Six samples of bio-capped copper oxide nanoparticles were made from two bio-waste extracts: Punica granatum L. peels and Psidium guajava Linn. leaves. Extraction methods included soaking in water or hydroethanol and boiling in water. The samples were characterized using FT-IR, XRD, SEM, and TGA. Results showed organic residue capping on CuO nanoparticles varied based on the extract and capping medium used. The thermal stability of all CuO samples was observed to be high, as recorded from TGA patterns and confirmed by EDX analysis, which showed a high content of copper ranging from 10.1 to 36.1%. TEM analysis revealed an average particle size of less than 20 nm for all six samples, suggesting a similarity in size. The soaking technique produced the most stable bio-capped CuO nanoparticles with a high negative zeta potential value. According to the study, the CuO samples synthesized from aqueous extracts obtained through soaking showed the highest antibacterial activity. This could be attributed to the high oxygen ratio, which was confirmed via EDX analysis. The bio-capped CuO was effective against multidrug- resistant gram-positive bacteria MRSA, and C. albicans. A mechanism was proposed to explain how the capping media affected the antimicrobial activity of the bio-capped CuO nanoparticles.

description: Gliese 569B is a multiple brown dwarf system whose exact nature has been the subject of several investigations over the past few years. Interpretation has partially relied on infra-red photometry and spectroscopy of the resolved components of the system. We present seeing limited Ks photometry over four nights, searching for variability in this young low mass substellar system. Our photometry is consistent with other reported photometry, and we report the tentative detection of several periodic signals consistent with rotational modulation due to spots on their surfaces. The five significant periods range from 2.90 hours to 12.8 hours with peak to peak variabilities from 28 mmag to 62 mmag in the Ks band. If both components are rotating with the shortest periods, then their rotation axes are not parallel with each other, and the rotation axis of the Bb component is not perpendicular to the Ba-Bb orbital plane. If Bb has one of the longer rotational periods, then the Bb rotation axis is consistent with being parallel to the orbital axis of the Ba-Bb system.

description: We investigate the simple harmonic oscillator in a 1-d box, and the 2-d isotropic harmonic oscillator problem in a circular cavity with perfectly reflecting boundary conditions. The energy spectrum has been calculated as a function of the self-adjoint extension parameter. For sufficiently negative values of the self-adjoint extension parameter, there are bound states localized at the wall of the box or the cavity that resonate with the standard bound states of the simple harmonic oscillator or the isotropic oscillator. A free particle in a circular cavity has been studied for the sake of comparison. This work represents an application of the recent generalization of the Heisenberg uncertainty relation related to the theory of self-adjoint extensions in a finite volume.

description: An effective ligand for the Ullmann-type C–N coupling reaction in water has been obtained using a novel tactic, namely, introducing a third group into the ligand to both improve the ligand’s water solubility and enhance the ligand’s coordinating ability. Applying this method, we have developed an effective ligand for the Cu-catalyzed amination of aryl halides, in particular, for aryl chlorides in water. The substrate diversity of the catalyst system, relatively less time required (6–12 h), and water as the reaction solvent make it attractive in both academia and industry.

description: Microbial resource centers (MRCs) have offered services to the scientific community for centuries.In the Internet era, many efforts have been undertaken to integrate their data and services (1). The EU project Common Access to Biological Resources and Information (CABRI) implemented unified access to culture collection catalogues, also guaranteeing a common level of quality of material and related information. Its network services were set up in 2000 and are still running, providing information on more than 100,000 microbiological resources, mainly microbial strains, and allowing researchers to get in touch with collections and order strains of interest.In 2004, the European Strategic Forum for Research Infrastructure (ESFRI) programme was launched by the European Community, aiming at reorganizing all research infrastructures into a coherent cluster of interoperating initiatives. In the context of the ESFRI programme, the Microbial Resource Research Infrastructure (MIRRI) started its preparatory phase in 2012 aiming to provide

a wealth of microbial resources, associated data, taxonomic methods, and expertise to serve users' needs (www.mirri.org).

description: Theoretical frameworks to estimate the tolerance of metabolic networks to various failures are important to evaluate the robustness of biological complex systems in systems biology. In this paper, we focus on a measure for robustness in metabolic networks, namely, the impact degree, and propose an approximation method to predict the probability distribution of impact degrees from metabolic network structures using the theory of branching process. We demonstrate the relevance of this method by testing it on real-world metabolic networks. Although the approximation method possesses a few limitations, it may be a powerful tool for evaluating metabolic robustness.

description: We have searched the WISE first data release for widely separated (<10,000AU) late T dwarf companions to Hipparcos and Gliese stars. We have discovered a new binary system containing a K-band suppressed T8p dwarf WISEP J1423+0116 and the mildly metal poor ([Fe/H]=-0.38+-0.06) primary BD+01 2920 (Hip 70319), a G1 dwarf at a distance of 17.2pc. This new benchmark has Teff=680+-55K and a mass of 20-50 Mjup. Its spectral properties are well modelled except for known discrepancies in the Y and K bands. Based on the well determined metallicity of its companion, the properties of BD+01 2920B imply that the currently known T dwarfs are dominated by young low-mass objects. We also present an accurate proper motion for the T8.5 dwarf WISEP J075003.84+272544.8.

Narrative competence in young children

subject: Storytelling ability in children

description: Bibliography: p. 256-275.
description: The focus of this naturalistic field study was the emergent narrative competence of children in both a grade one and a kindergarten classroom. Oral stories were collected at a story/talk centre over the three month course of the investigation which involved over 200 hours of on-site data gathering. With freedom to participate and choose topics, the children volunteered 413 stories for audiotaping during ongoing classroom activities. Informal interviews with the children and their teachers, and extensive field notes provided a broad contextual base. A qualitative analysis was selected after the data gathering was complete, to honour the emergent nature of the research thrust and to portray 1) how narrative competence unfolds as children gradually gain oral and literate fluency, 2) the nature of the storying behaviours disclosed and 3) the aspects of storying that are mastered or those in which the children are struggling to gain proficiency. Significant features of the stories were examined in terms of basic literary information. Key sound and visual components from interpersonal and intrapersonal interactions were investigated which reflected child/story and children/stories relationships. A further examination of these interactions and relationships revealed communicative aspects which were notable in terms of a child's perception of audience and of personal performance. Competence was examined from the perspectives of play and knowing by becoming; the study confirmed the social aspects of narrative. The model which emerged suggests a continuum along which these young children are moving as they acquire narrative proficiency. It consists of a series of three phases (comprising various subsidiary evolutions) through which children maneuvre in their development of narrative competence. The first phase is perceived as a time of receptive resonances wherein a child demonstrates the acquisition of intonation patterns. In the second phase, a child produces story scripts and string stories, demonstrates an emerging metanarrative sense, can provide longer sections of memorized stories, and attempts original story creations. In the third aspect authorial independence emerges with a shift from a linguistic to a communicational model. Story is perceived to be a special form of communication based on shared implicit formats. Correct referential voice provides an integrated quality to a story as a child uses a balance of counterpointed strategies which involve audience awareness, mobility of perspective, dialogue, and collusion with a listener. A child develops a personal style and may become absorbed and immersed in the story.

description: We derive some basic equations related to the redshift drift and we show how some dark energy (DE) properties can be retrieved from it. We consider in particular three kinds of DE models which exhibit a characteristic signature in their redshift drift while no such signature would be present in their luminosity-distances: a sudden change of the equation of state parameter w_{DE} at low redshifts, oscillating DE and finally an equation of state with spikes at low redshifts. Accurate redshift drift measurements would provide interesting complementary probes for some of these models and for models with varying gravitational coupling. While the redshift drift would efficiently constrain models with a spike at z~1, the signature of the redshift drift for models with large variations at very low redshifts z<0.1 would be unobservable, allowing a large arbitrariness in the present expansion of the universe.

description: Die vorliegende Masterarbeit beschäftigt sich mit dem Zusammenhang von Sprache und Zugehörigkeit und siedelt sich in der kritischen Migrationsforschung an. Die forschungsleitende Frage lautet, wie in Südtirol lebende Jugendliche mit Migrationsgeschichte im Hinblick auf die Differenzlinie „Sprache“ positioniert werden. Somit ist das Ziel der Arbeit, selbst- und fremdbezügliche Subjektpositionierungen in Bezug auf Sprache als Zugehörigkeits- und Differenzmerkmal von mehrsprachigen Jugendlichen, die entweder selbst oder dessen Eltern nach Südtirol migriert sind, zu explizieren. Der empirisch angelegten Studie geht eine theoretische Darlegung des Zusammenhangs von (Nicht-)Zu-gehörigkeit, Migrationsbewegungen und Sprachgebrauch sowie eine Erläuterung des vorherrschenden alltagstheoretischen Diskurses zu Südtirols vielfältiger Sprach- und Zugehörigkeitslandschaft voraus. In einem biographisch-narrativen Interview wurden acht Jugendliche zu ihrer Lebensgeschichte mit Schwerpunkt auf Sprache:n befragt, wovon drei ausgewählte Fälle mithilfe der Narrations- und Positionierungsanalyse interpretiert wurden. Die Rekonstruktion und anschließende Kontrastierung der Einzelfälle zeigen auf, dass die befragten Jugendlichen vorwiegend als Italienischsprecher:innen und nicht-dialektkompetent fremdpositioniert werden. Die Befragten nehmen ihre Erstsprache, die weder Deutsch noch Italienisch ist, als grundlegendes Zugehörigkeitsmerkmal wahr. Das Heranwachsen in Südtirol, einer multilingualen und -kulturellen Region, die sich durch eine Sprach(gruppen)trennung charakterisiert, hat beträchtliche Auswirkungen auf ihren Sprachgebrauch sowie ihr Zugehörigkeitsgefühl. Es ist Zeit, die zugehörigkeitspolitischen Instrumente zu überdenken sowie über Mehrsprachigkeit in Zusammenhang mit Diskriminierung und Rassismus an Südtirols Schulen zu sprechen.

description: Photoluminescent carbon nanoparticles (CNPs), such as carbon dots (CDs), have attracted much attention owing to a unique set of properties, like high and tunable fluorescence. In this way, the use of carbon-rich lignin has been demonstrated to be a sustainable approach to producing a broad range of photoluminescent CNPs. However, the valorization of this complex polyphenol is limited when it comes to green and efficient ways of conversion. In addition, the existing solvothermal approaches using lignin often result in CDs with low photoluminescence, while flammable and/or toxic solvents are employed. Here, we depolymerized technical lignins, i.e. kraft and soda, through electroreductive cleavage in two different sustainable media: deep eutectic solvent and levulinic acid. After depolymerization, lignin-derived monomers were generated, with a predominance of aryl ether and phenolic groups, which were further combined with 1,2-Phenylenediamine to produce N-doped CNPs in a solvent-free approach. Photoluminescent CNPs with varied sizes were generated (5–50 nm), which presented a wide photoluminescence emission, from blue to red, depending on solvent polarity. These results demonstrate a feasible and sustainable route for the solvent-free synthesis of photoluminescent CNPs using lignin-derived monomers as carbon source, which may find applications in a wide range of fields.

This requires to consider the need of semantic very early in the design process. The Intentional agent model is here exposed as a possible answer. It relies on a mixed imperative and declarative approach which focuses on the link between decision and action.

description: Two modified coated membrane sensors were designed and tested. Pantoprazole-phosphotungstate was prepared by a reaction of pantoprazole with phosphotungstic acid in the solvent mediator o-nitrophenyloctyl ether. Two metal oxide nanoparticles nickel oxide and iron oxide nanoparticles, were synthesized from green sources Matricaria recutita flowers and Salvia officinalis leaves extracts, respectively. These nanoparticles were used for the potentiometric assay of pantoprazole sodium in the authentic sample and commercial products. The results showed that the improved nickel oxide and iron oxide nanosensors exhibited linearity using the concentration range of 1.0 × 10−9–1.0 × 10−2 and 1.0 × 10−10–1.0 × 10−2 mol L−1, respectively compared with 1.0 × 10−6–1.0 × 10−2 mol L−1 for the normally coated sensor. The lower limits of detection (7.6 × 10−6, 2.3 × 10−10, 2.8 × 10−11 mol L−1) and quantification (1.0 × 10−6, 1.0 × 10−9, 1.0 × 10−10 mol L−1) were determined for each of the three proposed sensors. Least squares calculations gave EmV = (27.266 ± 0.5) log (pantoprazole) + 433.37, EmV = (30.967 ± 0.3) log (pantoprazole) + 432.24 for the enriched nano-metal oxides, and EmV = (26.642 ± 0.6) log (pantoprazole) + 443.69 for the conventional type, respectively with correlation coefficients around 0.999 for the proposed sensors. The accuracy and precision of the modified potentiometric systems were estimated and the results showed excellent validity and suitability for the determination of pantoprazole in an authentic sample.

description: We generalize the perturbations theory of loop quantum cosmology to a hydrodynamical form and define an effective curvature perturbation on an uniform density hypersurfaces $ζ_e$. As in the classical cosmology, $ζ_e$ should be gauge-invariant and conservation on the large scales. The evolutions of both the adiabatic and the non-adiabatic perturbations for a multi-fluids model are investigated in the framework of the effective hydrodynamical theory of loop quantum cosmology with the inverse triad correction. We find that, different from the classical cosmology, the evolution of the large-scales non-adiabatic entropy perturbation can be driven by an adiabatic curvature perturbation and this adiabatic source for the non-adiabatic perturbation is a quantum effect. As an application of the related formalism, we study a decay model and give out the numerical results.

description: We model "soft" error rates for writing (WSER) and for reading (RSER) for perpendicular spin-torque memory devices by solving the Fokker-Planck equation for the probability distribution of the angle that the free layer magnetization makes with the normal to the plane of the film. We obtain: (1) an exact, closed form, analytical expression for the zero-temperature switching time as a function of initial angle; (2) an approximate analytical expression for the exponential decay of the WSER as a function of the time the current is applied; (3) comparison of the approximate analytical expression for the WSER to numerical solutions of the Fokker-Planck equation; (4) an approximate analytical expression for the linear increase in RSER with current applied for reading; (5) comparison of the approximate analytical formula for the RSER to the numerical solution of the Fokker-Planck equation; and (6) confirmation of the accuracy of the Fokker-Planck solutions by comparison with results of direct simulation using the single-macrospin Landau-Lifshitz-Gilbert (LLG) equations with a random fluctuating field in the short-time regime for which the latter is practical.

description: Polyesters are important materials with a wide range of applications, but there has been increasing concern over their sustainability. One example is the need for safer, bio-derived solvents to replace those currently in use for the polymer’s synthesis and processing. In this work, several variants of the bio-based cellulose/levoglucosenone derived solvent Cyrene, namely the ketal derivatives dioxolane Cygnet, dioxane Cygnet and dioxepane Cygnet were synthesized and tested as media for enzymatic polycondensation reactions using bio-based building blocks. Dioxolane Cygnet and dioxepane Cygnet were found to be suitable solvents for enzymatic polycondensation reactions, with dioxolane Cygnet being the preferred solvent, yielding polymers with a Mn >22 kDa. In addition, these solvents were tested in the biocatalyzed synthesis of levoglucosenone-based polyesters. The alternative solvents gave superior yields to those previously observed, demonstrating the versatility of these solvents in enzymatic polycondensation reactions, representing the first synthetic polymer-solvent system fully derived from cellulose.

description: Between 1941 and 1962, scalar-tensor theories of gravitation were suggested four times by different scientists in four different countries. The earliest originator, the Swiss mathematician W. Scherrer, was virtually unknown until now whereas the chronologically latest pair gave their names to a multitude of publications on Brans-Dicke theory. P. Jordan, one of the pioneers of quantum mechanics theory, and Y. Thiry, a student of the mathematician A. Lichnerowicz, known by his book on celestial mechanics, complete the quartet. Diverse motivations for and conceptual interpretations of their theories will be discussed as well as relations among them. Also, external factors like language, citation habits, or closeness to the mainstream are considered. It will become clear why Brans-Dicke theory, although structurally a déjà-vu, superseded all the other approaches.

description: Biological Resource Centers are fundamental in harnessing and preserving the world's biodiversity, and play a vital role in driving innovation, and supporting the bioeconomy. MIRRI is an EU-ESFRI project involving a total of 33 partners and collaborating parties, aiming to provide facilitated access to microbial resources, associated data and expertise, and promote knowledge transfer. The importance of training and education activities towards reaching the goals of MIRRI is widely recognized, and emphasized by the inclusion of a dedicated work package focusing on these issues.

In order to assess the current panorama of education and training offer within MIRRI, a survey, via questionnaire, was elaborated and distributed within the consortium. The goal of this survey was to obtain a snapshot of training, current tools, and contents being used and produced within MIRRI. The questionnaire contained 11 multiple-choice questions, and a final, open-ended section for details and comments.

Here we present and analyze some of the results of this survey, and provide a first glimpse on the current setting, challenges, and possible solutions. The majority of MIRRI participants already provides training as part of their services or plans to implement it in the near future. Most noticeably, despite current trends and benefits in increased use and production of contents in new formats (e.g. video, interactive), training within MIRRI still has an overwhelming dominance of classic content types and delivery methodologies. Adopting new technologies would bring clear benefits to members of MIRRI and better serve the needs of our customers.

description: To help students address problems related to climate change, chemistry fundamentals are taught using sustainable principles. The principles of green chemistry and United Nations Sustainable Development Goals (SDGs) are guides to help us reach a sustainable future. Educators use these to create resources to connect green principles and sustainability goals. Systems thinking provides the method for creating relevant lectures, meaningful activities, and cohesive assessments in an educational module. A week-long stoichiometry module for introductory chemistry is described. Students tackle multiple learning outcomes to answer complex questions such as ‘what makes an reaction efficient?’. This module relates SDGs #7 and #13, clean energy and climate action, to the green principle of atom economy, which evaluates the efficiency of chemical transformations. The process of backward design is used with systems thinking to map learning outcomes across the module. Students demonstrate skills related to individual outcomes and use their knowledge to evaluate chemical systems from multiple perspectives across outcomes. Incorporating real-world examples the module explores how incomplete combustion impacts human health and the environment while exploring the material efficiency of making different fuels. The context and practice of sustainable science can be used to teach chemistry in a systematic way.
Space-time modelling of extreme events

description: Max-stable processes are the natural analogues of the generalized extreme-value distribution for the modelling of extreme events in space and time. Under suitable conditions, these processes are asymptotically justified models for maxima of independent replications of random fields, and they are also suitable for the modelling of joint individual extreme measurements over high thresholds. This paper extends a model of Schlather (2001) to the space-time framework, and shows how a pairwise censored likelihood can be used for consistent estimation under mild mixing conditions. Estimator efficiency is also assessed and the choice of pairs to be included in the pairwise likelihood is discussed based on computations for simple time series models. The ideas are illustrated by an application to hourly precipitation data over Switzerland.

description: Inspired by the recent proposed Legendre orthogonal polynomial representation of imaginary-time Green's functions, we develop an alternate representation for the Green's functions of quantum impurity models and combine it with the hybridization expansion continuous-time quantum Monte Carlo impurity solver. This representation is based on the kernel polynomial method, which introduces various integral kernels to filter fluctuations caused by the explicit truncations of polynomial expansion series and improve the computational precision significantly. As an illustration of the new representation, we reexamine the imaginary-time Green's functions of single-band Hubbard model in the framework of dynamical mean-field theory. The calculated results suggest that with carefully chosen integral kernels the Gibbs oscillations found in previous orthogonal polynomial representation have been suppressed vastly and remarkable corrections to the measured Green's functions have been obtained.

description: The generic features of parton energy loss effects on the quenching of single hadron spectra in heavy-ion collisions are discussed, paying attention to the expected differences from RHIC to LHC. The need for precise baseline measurements in p-Pb collisions at the LHC is also emphasized. Finally I briefly mention the production of prompt photons in heavy-ion collisions as well as some open questions.

description: We present a theory for carrier transport in semiconducting nanoscale heterostructures that emphasizes the effects of strain at the interface between two different crystal structures. An exactly solvable model shows that the interface region, or junction, acts as a scattering potential that facilitates charge separation but also supports bound interfacial states. As a case study, we model a Type-II CdS/ZnSe heterostructure. After advancing a theory similar to that employed in model molecular conductance calculations, we calculate the electron and hole photocurrents and conductances, including non-linear effects, through the junction at steady-state.
