description: Augmented Reality (AR) has been around for close to thirty years. However, it is only in the last decade that it has really become accessible to those outside of major technological industries. The work originally undertaken by research-based companies like Autonomy, based at Cambridge University in the UK, have gone a long way to enable the casual user to be able to adapt and engage with AR technology - despite the complexities involved in the programming necessary to make it actually work. The work presented here looks at exactly how AR can be implemented in the pursuit of enhancing the learning experience. It considers the usability of commercially available packages and presents some of the advantages of using such an approach to AR alongside the respective limitations. It goes on to look at the greater complexities of using “studio” based AR Software with the necessity of specific channel subscription in order to facilitate its use. The work presented is interactive and will not only describe AR and its use and limitations, through the use of AR itself, the work presented will actually showcase what is being presented in an interactive way.

description: In this paper, a methodological proposal is described to test for seasonal unit roots in weekly series of agricultural prices. When the deterministic seasonal component is not fixed over the sample, the tests for unit roots at seasonal frequencies tend to fail to reject the null hypothesis. This being the case, the original series are proposed to be filtered in order to remove the evolving deterministic seasonal component before applying standard procedures for testing for seasonal unit roots. In such a sense, the non-restricted evolving spline model (ESM) and the restricted evolving spline model (RESM) are shown to be useful parametric formulations to capture this type of deterministic seasonal pattern.

description: Unlike mainstream languages (such as English and French), low-resource languages often suffer from a lack of expert-annotated corpora and benchmark resources that make it hard to apply state-of-the-art techniques directly. In this paper, we alleviate this scarcity problem for the low-resourced Filipino language in two ways. First, we introduce a new benchmark language modeling dataset in Filipino which we call WikiText-TL-39. Second, we show that language model finetuning techniques such as BERT and ULMFiT can be used to consistently train robust classifiers in low-resource settings, experiencing at most a 0.0782 increase in validation error when the number of training examples is decreased from 10K to 1K while finetuning using a privately-held sentiment dataset.

description: Abstract: The proper functional interaction between different tissues represents a key component in systemic metabolic control. Indeed, disruption of endocrine inter-tissue communication is a hallmark of severe metabolic dysfunction in obesity and diabetes. Here, we show that the FNDC4-GPR116, liver-white adipose tissue endocrine axis controls glucose homeostasis. We found that the liver primarily controlled the circulating levels of soluble FNDC4 (sFNDC4) and lowering of the hepatokine FNDC4 led to prediabetes in mice. Further, we identified the orphan adhesion GPCR GPR116 as a receptor of sFNDC4 in the white adipose tissue. Upon direct and high affinity binding of sFNDC4 to GPR116, sFNDC4 promoted insulin signaling and insulin-mediated glucose uptake in white adipocytes. Indeed, supplementation with FcsFNDC4 in prediabetic mice improved glucose tolerance and inflammatory markers in a white-adipocyte selective and GPR116-dependent manner. Of note, the sFNDC4-GPR116, liver-adipose tissue axis was dampened in (pre) diabetic human patients. Thus our findings will now allow for harnessing this endocrine circuit for alternative therapeutic strategies in obesity-related pre-diabetes.

description: The low-temperature (LT) superstructure of $α'$-NaV$_2$O$_5$ was determined by synchrotron radiation x-ray diffraction. Below the phase transition temperature associated with atomic displacement and charge ordering at 34K, we observed the Bragg peak splittings, which evidence that the LT structure is monoclinic. It was determined that the LT structure is $(a-b)\times 2b \times 4c$ with the space group $A112$ where $a, b$ and $c$ represent the high temperature orthorhombic unit cell. The valence estimation of V ions according to the bond valence sum method shows that the V sites are clearly separated into two groups of V$^{4+}$ and V$^{5+}$ with a $zigzag$ charge ordering pattern. This LT structure is consistent with resonant x-ray and NMR measurements, and strikingly contrasts to the LT structure previously reported, which includes V$^{4.5+}$ sites.

description: The global food system is estimated to contribute to 30% of total Greenhouse gas emissions. The issue of how to incentivize consumers modifying their diet is crucial. We consider here food taxation scenarios aiming at reducing environmental emissions through different CO2tax options. Data proceed from Kantar purchases for food-at-home of French households on the 1998-2010 period. Our main result is that a uniform tax scenario, set at a 20% rate, induces a greater emissions reduction than a proportional to emissions tax scenario, based on a 50€/tCO2 carbon cost. Therefore a 20% tax scenario on targeted foods could result in a better incentive to consumer choices in an environmental perspective. Moreover, the implementation of a VAT increase is probably easier than any other tax regulation.

description: The environmental impact of food is a major concern for climate change. This paper estimates the CO2 emissions due to food purchases of French households and analyses the disparities between income classes. To combine environment with health concerns, we consider as well the caloric content of foods and normalize CO2 emissions on a daily 2000kcalories basis. Data on French food purchases come from Kantar 1998-2010. Using Life-Cycle-Analysis from Greenext, we obtain CO2equivalent emissions for different food groups. Then we adjust levels of emissions by linear regression on income and age. We find that CO2 emissions of food purchases amount to 3.9kg/day/household. Lowest-income households emit more CO2 compared to richest households (+14.7%), but less on an adjusted 2000kcal basis (-9.6%). In a public policy perspective, richer households should be the first target of diet change since their consumption favours higher CO2 emitting food groups than lower-income households, at caloric level constant.

description: Low demand for index insurance in several recent pilot programs has created a puzzle for development economists and policy makers concerned with enhancing farmers risk management capacity in low-income economies. This paper contributes to the resolution of this puzzle by providing empirical evidence on the relative effectiveness of two primary frameworks for modeling decision-making under uncertainty. Specifically, we test whether features of Cumulative Prospect Theory (CPT), or Expected Utility Theory (EUT), better predict farmers' demand for crop insurance. Whereas in EUT, risk preferences can be represented by a single risk aversion parameter, in CPT they are determined by at least four components: probability weighting, the curvature of a utility function, a reference income and loss aversion. The data come from a series of unframed and framed lotteries played with 480 small-holder cotton farmers in southern Peru. The unframed risk games allow us to measure individual-specific preference parameters, for both theories. We use these parameters to generate predictions of farmers' choices in two framed insurance games in which farmers choose to purchase one of two available insurance contracts or to purchase no insurance. In the first game, farmers' earnings are framed as gross revenues and are always positive, i.e., this game is played over gains. In the second game, earnings are framed as net revenues and may be either positive or negative so that this is a game played over mixed prospects. We test the relative performance of the two theories by comparing the predictions of farmers' choices versus their actual choices in the insurance games. An important finding with respect to marketing of insurance contracts is that framing incomes as net revenues instead of gross revenues increases the CPT predicted demand by 24%. In the actual insurance games however, only 8% more farmers chose insurance in the net revenues frame. We find that neither theory is a particularly strong predictor of insurance choices, although EUT fares better than CPT for better educated farmers.

description: It is a challenge for many researchers to separate volatile compounds. In this study, we introduce a rapid and efficient method of separating target compound from the twigs of Cinnamomum cassia by high performance counter-current chromatography. Under the bioassay guidance, the total extract exhibited a potential activity against NO production in RAW 264.7 macrophages and the total extract was further separated by high performance counter-current chromatography. Cinnamaldehyde (1) was enriched by counter-current chromatography (CCC) with reversed-phase mode using n-hexane–ethyl acetate–methanol–water (1:1:1:1,v/v/v/v) as the solvent system. Further identification was achieved by high performance liquid chromatography (HPLC).

description: Abstract: Bacteria can chemotactically migrate up attractant gradients by controlling run-and-tumble motility patterns. In addition to this well-known chemotactic behaviour, several soil and marine bacterial species perform chemokinesis; they adjust their swimming speed according to the local concentration of chemoeffector, with higher speed at higher concentration. A field of attractant then induces a spatially varying swimming speed, which results in a drift towards lower attractant concentrations—contrary to the drift created by chemotaxis. Here, to explore the biological benefits of chemokinesis and investigate its impact on the chemotactic response, we extend a Keller–Segel-type model to include chemokinesis. We apply the model to predict the dynamics of bacterial populations capable of chemokinesis and chemotaxis in chemoeffector fields inspired by microfluidic and agar plate migration assays. We find that chemokinesis combined with chemotaxis not only may enhance the population response with respect to pure chemotaxis, but also modifies it qualitatively. We conclude presenting predictions for bacteria around dynamic finite-size nutrient sources, simulating, e.g. a marine particle or a root. We show that chemokinesis can reduce the measuring bias that is created by a decaying attractant gradient. Graphic abstract:
Chaos and Chaotic Phase Mixing in Galaxy Evolution and Charged Particle Beams

description: This paper discusses three new issues that necessarily arise in realistic attempts to apply nonlinear dynamics to galaxy evolution, namely: (i) the meaning of chaos in many-body systems, (ii) the time-dependence of the bulk potential, which can trigger intervals of {\em transient chaos}, and (iii) the self-consistent nature of any bulk chaos, which is generated by the bodies themselves, rather than imposed externally. Simulations and theory both suggest strongly that the physical processes associated with galactic evolution should also act in nonneutral plasmas and charged particle beams. This in turn suggests the possibility of testing this physics in real laboratory experiments, an undertaking currently underway.

description: In this paper, we argue that discontinuous preference over certain and uncertain outcomes (as in Andreoni and Sprenger, 2009; 2012) have a dampening effect on the demand for insurance. The intuition is that if agents exhibit a disproportionate preference for certain outcomes, they would undervalue uncertain insurance indemnity payments compared to certain premium cost and exhibit lower demand for insurance compared to a classic expected utility maximizer. Inspired by the seminal work of Andreoni and Sprenger, we design games to identify agents with a disproportionate preference for certain outcomes and play them with 571 cotton farmers in Western Burkina-Faso. We then provide experimental evidence that this is a powerful framework to understand demand for micro-insurance. Specifically we show that agents with discontinuous preference respond positively to an alternative presentation of a classic insurance contract: they are willing to pay more for a given contract if the premium cost is artificially made uncertain by being directly deducted from indemnity payments. We also explore alternative behavioral arguments such as loss aversion but argue that they offer less appealing framework to understand the full set of our results. Our results have practical implications for the design of insurance contracts.

description: Robots extend beyond the tools of productivity; they also contribute to creativity. While typically defined as utility-driven technologies designed for productive or social settings, the role of robots in creative settings remains underexplored. This paper examines how robots participate in artistic creation. Through semi-structured interviews with robotic artists, we analyze the impact of robots on artistic processes and outcomes. We identify the critical roles of social interaction, material properties, and temporal dynamics in facilitating creativity. Our findings reveal that creativity emerges from the co-constitution of artists, robots, and audiences within spatial-temporal dimensions. Based on these insights, we propose several implications for socially informed, material-attentive, and process-oriented approaches to creation with computing systems. These approaches can inform the domains of HCI, including media and art creation, craft, digital fabrication, and tangible computing.

description: Quantum entanglement is a building block of the entangled quantum networks of the quantum Internet. A fundamental problem of the quantum Internet is entanglement distribution. Since quantum entanglement will be fundamental to any future quantum networking scenarios, the distribution mechanism of quantum entanglement is a critical and emerging issue in quantum networks. Here we define the method of opportunistic entanglement distribution for the quantum Internet. The opportunistic model defines distribution sets that are aimed to select those quantum nodes for which the cost function picks up a local minimum. The cost function utilizes the error patterns of the local quantum memories and the predictability of the evolution of the entanglement fidelities. Our method provides efficient entanglement distributing with respect to the actual statuses of the local quantum memories of the node pairs. The model provides an easily-applicable, moderate-complexity solution for high-fidelity entanglement distribution in experimental quantum Internet scenarios.

description: Individuals’ time preference is an important driver for several health-related behaviors, but there is still lack of knowledge about its relationship with specific food-related behaviors. In this paper we investigate if time preference may have a role in affecting consumers’ use of food label. The data were collected through a face-to-face survey on a sample of 540 Italian consumers. Time preference was estimated through an index including BMI, smoking behavior and physical activity. The analysis was made estimating a set of three equations. The results confirm our hypothesis that individuals with low time preference, who give more importance to future health outcomes, are more willing to use such information.

description: An approach is proposed to calculate Generalized Parton Distributions (GPDs) in a Constituent Quark Model (CQM) scenario. These off-diagonal distributions are obtained from momentum space wave functions to be evaluated in a given non relativistic or relativized CQM. The general relations linking the twist-two GPDs to the form factors and to the leading twist quark densities are consistently recovered from our expressions. Results for the leading twist, unpolarized GPD, H, in a simple harmonic oscillator model, as well as in the Isgur and Karl model, are shown to have the general behavior found in previous estimates. NLO evolution of the obtained distributions, from the low momentum scale of the model up to the experimental one, is also shown. Further natural applications of the proposed formalism are addressed.

description: Solid-solution bimetallic alloy catalysts containing no noble metals were developed via both simultaneous and sequential deposition in supercritical water (SCW). These bimetallic nano-catalysts were analyzed by Brunauer–Emmett–Teller, X-ray diffraction, X-ray photoelectron spectroscopy and transmission electron microscopy. Obvious downward shifts are observed in diffraction peaks, situated between the peak (1 1 1) for Co and the peak (1 1 1) for Ni. The shifts indicate the formation of NiCo solid-solution bimetallic alloy(s). The bimetallic nanoparticles show high activity for supercritical water gasification of phenol to produce gaseous fuels. The carbon gasification efficiency (CGE) of phenol in SCW can reach 95% on the Co–Ni/AC catalyst at conditions of 500°C and 30 min, showing nearly the same CGE as the commercial noble-metal-based catalyst, such as Ru/C (5 wt% Ru) from Sigma-Aldrich. The Co–Ni/AC catalyst also shows high stability. Therefore, deposition in SCW provides an effective way to create noble-metal-free solid-solution bimetallic alloy catalysts.

In each case we identify a subset of levels within a single rotational manifold suitable to implement a 4-level qudit. Quantum gates can be implemented using two-photon microwave transitions via levels in a neighboring rotational manifold. We discuss limitations to the usefulness of molecular qudits, arising from off-resonant excitation and decoherence. As an example, we present a protocol for using a molecular qudit of dimension $d=4$ to perform the Deutsch algorithm.

description: We study the quantum corrections to the Fermi energy of a two-dimensional electron system, showing that it is attracted towards the Van Hove singularity for a certain range of doping levels. The scaling of the Fermi level allows to cure the infrared singularities left in the BCS channel after renormalization of the leading logarithm near the divergent density of states. A phase of d-wave superconductivity arises beyond the point of optimal doping corresponding to the peak of the superconducting instability. For lower doping levels, the condensation of particle-hole pairs due to the nesting of the saddle points takes over, leading to the opening of a gap for quasiparticles in the neighborhood of the singular points.

description: Abstract: We present the first estimate of green snow algae community biomass and distribution along the Antarctic Peninsula. Sentinel 2 imagery supported by two field campaigns revealed 1679 snow algae blooms, seasonally covering 1.95 × 106 m2 and equating to 1.3 × 103 tonnes total dry biomass. Ecosystem range is limited to areas with average positive summer temperatures, and distribution strongly influenced by marine nutrient inputs, with 60% of blooms less than 5 km from a penguin colony. A warming Antarctica may lose a majority of the 62% of blooms occupying small, low-lying islands with no high ground for range expansion. However, bloom area and elevation were observed to increase at lower latitudes, suggesting that parallel expansion of bloom area on larger landmasses, close to bird or seal colonies, is likely. This increase is predicted to outweigh biomass lost from small islands, resulting in a net increase in snow algae extent and biomass as the Peninsula warms.

description: The QCD baryon number density can formally be expanded into a Laurent series in fugacity, which is a relativistic generalization of Mayer's cluster expansion. We determine properties of the cluster expansion in a model with a phase transition and a critical point at finite baryon density, in which the Fourier coefficients of the expansion can be determined explicitly and to arbitrary order. The asymptotic behavior of Fourier coefficients changes qualitatively as one traverses the critical temperature and it is connected to the branch points of a thermodynamic potential associated with the phase transition. The results are discussed in the context of lattice QCD simulations at imaginary chemical potential. We argue that the location of a branch point closest to the imaginary chemical potential axis can be extracted through an analysis of an exponential suppression of Fourier coefficients. This is illustrated using the four leading coefficients both in a toy model as well as by using recent lattice QCD data.

description: This work presents the electronic and transport properties of bilayer borophene nanoribbons. In the first part, a four-orbital tight-binding model is derived by fitting the \emph{ab initio} band structure. The transport properties of armchair and zigzag bilayer borophene nanoribbons are then analyzed, both with and without periodic boundary conditions. In both scenarios, the nodal line causes conductance to increase with width and exhibit oscillations in narrow nanoribbons. Additionally, plots of current and charge density reveal that edge states have a more pronounced impact in narrower nanoribbons. Finally, uniaxial tensile strain is introduced as a tool to engineer the number of available transport channels.

description: Agriculture is the backbone of Central Asia’s (CA) economy providing economic and social stability in the region. Sustainable use of agricultural land is therefore of critical importance to economic growth, human well-being and social equity, and ecosystem services. However, severe land degradation through salinization, erosion and desertification is evident and respective impacts on human health and ecosystem services are suspected. This paper aims to analyze current research on agricultural land use in CA through applying the Land Use Functions framework. In particular, it examines the type and relative shares of environmental, economic and social aspects of agricultural land use addressed in existing scientific literature. This study analyzed scientific publications dealing with agricultural land use in five CA countries: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. A systematic database search of international peer-reviewed articles was conducted using the ISI Web of Science. We selected the English-language articles that were published between 2008 and 2013. After the analysis of paper titles, abstracts and keywords, we found 362 articles relevant to agricultural land use in CA. The analysis indicated that publications concentrating on environmental and economic dimensions of land use functions were primary focus of land use scientists. By contrast, social aspects of land use functions, such as employment, human health and recreational services, and landscape aesthetics received far less importance by international scholars. Interestingly, large portion of articles focused on issues of agricultural land use in Uzbekistan. This is due to the fact that the country extensively benefited from large international research projects in the last decade. By applying the Land Use Functions framework, we identified international research focus and knowledge gaps that future scientists can contribute to the sustainability of agricultural land use in CA.

description: Three kinds of polycarboxylate ether (PCE) polymers with the same length of side chains but different backbone length were synthesized by aqueous free radical polymerization. Adding counter-ions (i.e., Na+, Ca2+) to dilute PCE solutions was found to induce a more complicated conformational change, since the screening of the electrostatic intramolecular repulsion and the different complexation behaviors of Ca2+ with carboxylic groups. Further characterization on the adsorption indicated that the differences of the adsorption ability resulted from the difference in the solution conformation of PCE molecule. PCE of a medium backbone length studied herein possesses a more extended polymer backbone due to the intermolecular steric hindrance, which result in more carboxylic groups could be accessible for adsorption. Obviously, the solution conformation of PCE strongly impacts the accessible carboxylic group contribution to adsorption. In this way it may provide a new insight to design the polymer structures of PCE with superior adsorption ability.

description: A general framework for proving an order of convergence for set-valued Runge Kutta methods is given in the case of linear differential inclusions, if the attainable set at a given time should be approximated. The set-valued method is interpreted as a (set-valued) quadrature method with disturbed values for the fundamental solution at the nodes of the quadrature method. If the precision of the quadrature method and the order of the disturbances fit together, then an overall order of convergence could be guaranteed. The framework is applied to several Runge-Kutta methods up to order 4 with different selections strategies, i.e. piecewise constant, piecewise linear, two and more independent choices. Several numerical examples are calculated and the corresponding attainable sets are shown.
Understanding the spectra of isolated Herbig stars in the frame of a passive disk model

description: We discuss spectral energy distributions of a sample of Herbig Ae/Be stars in the context of a passive irradiated disk model. The data have been presented earlier by Meeus et al (2001), and preliminary interpretations of these data were given in that paper. While the spectra of Herbig Ae stars all show similarities, there is significant variation between the spectra, in particular in the shape of the mid-IR rise and in the presence or absence of a silicate feature. We explore the hypothesis that all these different spectra can be interpreted as pure disk spectra without additional components. Using the model of Dullemond, Dominik and Natta (2001) we deduce the disk parameters of a number of the sources, and find that for a large fraction of investigated sources, satisfactory fits can be obtained. The derived model parameters show that some group Ia sources can only be fit with radially increasing surface densities, indicating the presence of depleted inner disk regions. The steep-sloped SEDs of group IIa sources can be fit with very compact disks, probably representing disks with collapsed outer regions. The largest difficulties arise from sources that do not show significant silicate emission features. Our attempts to explain these objects with a pure geometric effect are only partially successful. It seems that these stars indeed require a strong depletion of small silicate grains.

Diverse outcomes of planet formation and composition around low-mass stars and brown dwarfs

description: The detection of Earth-size exoplanets around low-mass stars -- in stars such as Proxima Centauri and TRAPPIST-1 -- provide an exceptional chance to improve our understanding of the formation of planets around M stars and brown dwarfs. We explore the formation of such planets with a population synthesis code based on a planetesimal-driven model previously used to study the formation of the Jovian satellites. Because the discs have low mass and the stars are cool, the formation is an inefficient process that happens at short periods, generating compact planetary systems. Planets can be trapped in resonances and we follow the evolution of the planets after the gas has dissipated and they undergo orbit crossings and possible mergers. We find that formation of planets above Mars mass and in the planetesimal accretion scenario, is only possible around stars with masses $M_{\star} \ge 0.07 M_{sun}$ and discs of $M_{disc} \ge 10^{-2}~M_{sun} $. We find that planets above Earth-mass form around stars with masses larger than $0.15 M_{\oplus}$ while planets larger than $5 M_{\oplus}$do not form in our model, even not under the most optimal conditions (massive disc), showing that planets such as GJ 3512b form with another, more efficient mechanism. Our results show that the majority of planets form with a significant water fraction; that most of our synthetic planetary systems have 1, 2, or 3 planets, but those with 4, 5, 6, and 7 planets are also common, confirming that compact planetary systems with many planets should be a relatively common outcome of planet formation around small stars.
