description: Fusion power plants will need to run in a reliable way, in order to maximize the power output and avoid delays due to unscheduled maintenance or damage to components. Predictive maintenance is an approach that can contribute to this requirement by periodic or continuous monitoring of the condition of equipment. The goal is to predict when the equipment will require maintenance and, ultimately, to provide an estimate of the remaining useful lifetime of devices and components. This allows better maintenance scheduling and can help to avoid damage due to equipment failure. In this work, we introduce several statistical techniques that can be employed toward predictive maintenance in fusion devices. More specifically we then present an application of condition monitoring to circuit breakers in the JET Ohmic heating circuit, powering the central solenoid. These circuit breakers are an important cause of failed pulses at JET, because they endure physical fatigue due to the large currents required for plasma formation. Using voltage and current data in the circuit, we employ Otsu method adapted for time series in order to determine if the circuit breakers operate in a healthy or anomalous state. In general, this approach can provide an advance warning of the deteriorating condition of subsystems and components in fusion devices, allowing maintenance as needed and preventing asset damage.

description: The international Monitory Fund (IMF) has been working with Sudan since 1997 to implement macroeconomic reforms including a managed float of the exchange rate (EXR). The IMF sees the EXR flexibility as key to safeguard and rebuild foreign exchange reserves and essential to meet the international reserve target in Sudan. However, the authorities in Sudan are concerned that greater exchange rate flexibility could contribute to inflationary pressures. In addition, a review of literature focusing on the exchange rate policies in Sudan reflects huge ambiguity about its outcome. This calls for additional empirical investigations that provide economy wide assessments of the various possible scenarios that could be adopted in the Sudanese context. Accordingly, the current paper applies an economy-wide impact assessment tool to investigate the possible effects of devaluating the overvalued (according to the IMF, 2009) Sudanese pound. Namely, it uses a Computable General Equilibrium (CGE) model together with its detailed database of Sudan to simulate the Sudanese pound to depreciate according to three different scenarios by 5%, 10%, and 15%. Results of the paper recommend that the additional flexibility in the Sudanese EXR regime suggested by the IMF should be carefully considered if that would lead the value of the Sudanese currency to be devalued. This imply that the authorities in Sudan should closely monitor and control the EXR to avoid its depreciation in the short run, while encouraging both public and private investments to help creating additional jobs that increases domestic income and reduces the negative consequences of inflation.

description: As a consequence of greenhouse forcing, all state of the art general circulation models predict a positive temperature trend that is greater for the troposphere than the surface. This predicted positive trend increases in value with altitude until it reaches a maximum ratio with respect to the surface of as much as 1.5 to 2.0 at about 200 to 400 hPa. However, the temperature trends from several independent observational data sets show decreasing as well as mostly negative values. This disparity indicates that the three models examined here fail to account for the effects of greenhouse forcings.

description: Grip force control during robotic in-hand manipulation is usually modeled as a monolithic task, where complex controllers consider the placement of all fingers and the contact states between each finger and the gripped object in order to compute the necessary forces to be applied by each finger. Such approaches normally rely on object and contact models and do not generalize well to novel manipulation tasks. Here, we propose a modular grip stabilization method based on a proposition that explains how humans achieve grasp stability. In this biomimetic approach, independent tactile grip stabilization controllers ensure that slip does not occur locally at the engaged robot fingers. Local slip is predicted from the tactile signals of each fingertip sensor i.e., BioTac and BioTac SP by Syntouch. We show that stable grasps emerge without any form of central communication when such independent controllers are engaged in the control of multi-digit robotic hands. The resulting grasps are resistant to external perturbations while ensuring stable grips on a wide variety of objects.

description: In many places, growing population, in conjunction with efforts to increase food security, is escalating pressure to expand agriculture within wetlands. The environmental impact of wetland agriculture can have profound social and economic repercussions for people dependent on ecosystem services other than those provided directly by agriculture. If wetlands are not used sustainably, the functions which support agriculture, as well as other food security and ecosystem services, are undermined. This report synthesizes findings from multidisciplinary studies conducted into sustainable wetland agriculture by IWMI and partners in Africa and Asia. It highlights the value of wetland agriculture for poverty reduction as well as the need for more systematic planning that takes into account trade-offs in the multiple services that wetlands provide.

description: Ellipsoidal variables present light-curve modulations caused by stellar distortion, induced by tidal interaction with their companions. An analytical approximated model of the ellipsoidal modulation is given as a discrete Fourier series by Morris and Naftilan 1993 (MN93). Based on numerical simulations using the PHOEBE code we present here updated amplitudes of the first three harmonics of the model. The expected amplitudes are given as a function of the mass ratio and inclination of the binary system and the fillout factor of the primary---the ratio between the stellar radius and that of its Roche lobe. The corrections can get up to 30% relative to the MN93 model for fillout factors close to unity. The updated model can be instrumental in searching for short-period binaries with compact-object secondaries in large data sets of photometric light curves. As shown in one OGLE light-curve example, the minimum mass ratio can be obtained by using only the amplitudes of the three harmonics and an estimation of the stellar temperature. High enough amplitudes can help to identify binaries with mass ratios larger than unity, some of which might have compact companions.

description: Mineral dust composition affects a multitude of processes in the atmosphere and adjacent compartments. Dust dry deposition was collected near source in northwest Africa, in Central Asia, and on Svalbard and at three locations of the African outflow regime. Samples were subjected to automated scanning electron microscopy with energy-dispersive X-ray analysis to obtain size and composition of 216,000 individual particles. Results show low temporal variation in estimated optical properties for each location, but considerable differences between the African, Central Asian, and Arctic regimes. No significant difference was found between the K-feldspar relative abundances, indicating comparable related ice-nucleation abilities. The mixing state between calcium and iron compounds was different for near source and transport regimes, potentially in part due to size sorting effects. As a result, in certain situations (high acid availability, limited time) atmospheric processing of the dust is expected to lead to less increased iron solubility for near-source dusts (in particular for Central Asian ones) than for transported ones (in particular of Sahelian origin).

description: Bosnia Herzegovina (BH) is in the process of joining the World Trade Organization in the near future and the European Union in the medium term. As a net agriculture and food importer, accession will require BH to expose some of its inefficient and sensitive agricultural industries, such as meat and dairy products, to international competition. A bilateral trade model is used to estimate the potentially negative impacts of accession on production and trade in several specific sectors. According to the research results, BH imports are estimated to increase, driven by the livestock products sector. Exports are only marginally affected. A drop in overall customs revenues is expected. BH is expected to experience a small reduction in agricultural sector welfare following accession to the EU or the WTO. The implications for poverty are likely to be negative, especially for meat producers. On the other hand the main beneficiaries will be the consumers. This presumes that lower border prices are passed through to domestic consumers.

description: We have obtained optical spectra of four galaxies associated with MgII QSO absorbers at redshifts 0.10 < z < 0.45. We calculate the gas-phase oxygen abundance of these galaxies using the empirical R23 strong line method. The absolute B-band magnitudes of the galaxies span -20.6 < M_B < -18.3. If the metallicities lie on the R23 upper branch (8.4 < log (O/H) + 12 < 8.9), then the metallicities of these absorption selected galaxies span the range between 0.5--1.4 solar and would be consistent with the well-known luminosity-metallicity relation for 0.10 < z < 0.45 emission-line galaxies. However, such metallicities would be 0.5--1.0 dex higher than those observed in damped Lyman alpha systems (DLAs) via absorption line measurements at similar redshifts. Conversely, the lower R23 branch calibration yields metallicities approximately 1/7 solar, consistent with the DLA absorption metallicities at low redshifts. In this case, the absorption selected galaxies would lie significantly lower than the luminosity-metallicity relation for emission-line galaxies at z<0.5. We discuss the implications and possible solutions for each scenario.

description: In a large recommender system, the products (or items) could be in many different categories or domains. Given two relevant domains (e.g., Book and Movie), users may have interactions with items in one domain but not in the other domain. To the latter, these users are considered as cold-start users. How to effectively transfer users' preferences based on their interactions from one domain to the other relevant domain, is the key issue in cross-domain recommendation. Inspired by the advances made in review-based recommendation, we propose to model user preference transfer at aspect-level derived from reviews. To this end, we propose a cross-domain recommendation framework via aspect transfer network for cold-start users (named CATN). CATN is devised to extract multiple aspects for each user and each item from their review documents, and learn aspect correlations across domains with an attention mechanism. In addition, we further exploit auxiliary reviews from like-minded users to enhance a user's aspect representations. Then, an end-to-end optimization framework is utilized to strengthen the robustness of our model. On real-world datasets, the proposed CATN outperforms SOTA models significantly in terms of rating prediction accuracy. Further analysis shows that our model is able to reveal user aspect connections across domains at a fine level of granularity, making the recommendation explainable.

description: Finite element model updating utilizing frequency response functions as inputs is an important procedure in structural analysis, design and control. This paper presents a highly efficient framework that is built upon Gaussian process emulation to inversely identify model parameters through sampling. In particular, a multi-response Gaussian process (MRGP) meta-modeling approach is formulated that can accurately construct the error response surface, i.e., the discrepancies between the frequency response predictions and actual measurement. In order to reduce the computational cost of repeated finite element simulations, an adaptive sampling strategy is established, where the search of unknown parameters is guided by the response surface features. Meanwhile, the information of previously sampled model parameters and the corresponding errors is utilized as additional training data to refine the MRGP meta-model. Two stochastic optimization techniques, i.e., particle swarm and simulated annealing, are employed to train the MRGP meta-model for comparison. Systematic case studies are conducted to examine the accuracy and robustness of the new framework of model updating.

description: The goal of this study is to estimate how different price or quantity fixing contracts affect the value of pig space unit in pig fattening. The value of pig space unit is estimated with a stochastic dynamic programming algorithm. The model maximises the value of pig space unit by using four decision variables. The input-output ratios are endogenous and the option to suspend production temporarily is taken into account in the model. The results suggests that the smooth functioning of markets in Finland can be promoted by ensuring that price changes are transmitted smoothly between input and output markets, and that producers are compensated for giving up the option to suspend production temporarily in the event if unfavourable market situation. Instead of fixing only the price of output, the contract should aim at reducing the risk associated with gross margin.

description: International agricultural trade has been growing significantly during the last decade. Many countries rely on imports to ensure adequate food supplies to the people. A few are becoming food baskets of the world. This process raises issues about the food security in depending countries and potentially unsustainable land and water use in exporting countries. In this paper, we analyse the impacts of amplified farm trade on natural resources, especially water. Farm exports and imports of five Latin America countries (Brazil, Argentina, Mexico, Peru and Chile) are examined carefully. A preliminary analysis indicates that virtual water imports can save valuable water resources in water-short countries, such as Mexico and Chile. Major exporting countries, including Brazil and Argentina, have become big exporters due to abundant natural resource endowments. The opportunity costs of agricultural production in those countries are identified as being low, because of the predominant green water use. It is concluded that virtual water trade can be a powerful tool to alleviate water stress in semi-arid countries. However, for exporting nations a sustainable water use can only be guaranteed if environmental production costs are fully reflected in the commodity prices. There is no basis for erecting environmental trade tariffs on exporters though. Setting up legal foundations for them in full compliance with WTOs processes would be a daunting task.

description: Accurate active galactic nucleus (AGN) identifications and spatially resolved host galaxy properties are a powerful combination for studies of the role of AGNs and AGN feedback in the coevolution of galaxies and their central supermassive black holes. Here, we present robust identifications of 406 AGNs in the first 6261 galaxies observed by the integral field spectroscopy survey Mapping Nearby Galaxies at Apache Point Observatory (MaNGA). Instead of using optical line flux ratios, which can be difficult to interpret in light of the effects of shocks and metallicity, we identify the AGNs via mid-infrared WISE colors, Swift/BAT ultra hard X-ray detections, NVSS and FIRST radio observations, and broad emission lines in SDSS spectra. We subdivide the AGNs into radio-quiet and radio-mode AGNs, and examine the correlations of the AGN classes with host galaxy star formation rates and stellar populations. When compared to the radio-quiet AGN host galaxies, we find that the radio-mode AGN host galaxies reside preferentially in elliptical galaxies, lie further beneath the star-forming main sequence (with lower star formation rates at fixed galaxy mass), have older stellar populations, and have more negative stellar age gradients with galactocentric distance (indicating inside-out quenching of star formation). These results establish a connection between radio-mode AGNs and the suppression of star formation.

description: The negotiations on a deep and comprehensive free trade agreement (FTA) between Ukraine and the EU are currently in process. Such a FTA can be expected to imply opportunities as well as challenges for agricultural markets. This paper provides a model-based quantitative assessment of the potential impacts of a FTA on agricultural commodity markets in the EU and Ukraine. For the quantitative analysis the dynamic, partial equilibrium model AGLINK-COSIMO has been adapted and applied. The modules for the EU and Ukraine have been extracted from the global model and prepared to run together. Thus, the focus is on the bilateral trade positions and not on the effect on other countries. The simulation of a FTA between the EU and Ukraine was done through the elimination of import tariffs for main agricultural commodities. Results of the simulation indicate a positive change in producer revenue of 393 million € in Ukraine and of 860 million € in the EU. Thus, this FTA entails opportunities for the agricultural sectors of both trading partners. However, gains from a FTA are not distributed homogeneously and vary significantly among commodities.

description: Observations suggest that the earth's surface has been warming relative to the troposphere for the last 25 years; this is not only difficult to explain but also contrary to the results of climate models. We provide new evidence that the disparity is real. Introducing an additional data set, R2 2 meter temperatures, a diagnostic variable related to tropospheric temperature profiles, we find trends derived from it to be in close agreement with satellite measurements of tropospheric temperature. This suggests that the disparity likely is a result of near-surface processes. We find that the disparity does not occur uniformly across the globe, but is primarily confined to tropical regions which are primarily oceanic. Since the ocean measurements are sea surface temperatures, we suggest that the disparity is probably associated with processes at the ocean-atmosphere interface. Our study thus makes unlikely some of the explanations advanced to account for the disparity; it also demonstrates the importance of distinguishing between land, sea and air measurements

description: Thermoplastic composites are increasingly popular in the automotive industry thanks to lightweight, low cost, short cycle times and recyclability. When reinforced with short fibres (typically glass or carbon), they can be easily injection-moulded into complex shapes. However, compared with traditional thermoset composites (epoxy-based) or metals, they are more sensitive to environmental and loading conditions. Not only do ambient temperature and humidity affect the mechanical behaviour, but also the polymer matrix itself may heat up when deformed plastically (self-heating, thermomechanical coupling).The aim of this study is to characterise the tensile behaviour of injection-moulded short glass fibre-reinforced polyamide 6 (PA6) under conditions that are representative of applications. To capture the material complexity and thermo-mechanical coupling, a dedicated setup with digital image correlation (DIC) and infrared (IR) thermography is used to obtain synchronised, full-field measurements of strains and temperatures during the tests. The interplay between the strain, strain rate and temperature fields is studied for both pure PA6 and glass/PA6. Local self-heating may occur if the local strain rate is higher than a critical value. Significant temperature rises are observed in pure PA6 depending on the test speed, as a consequence of extensive plastic deformation. This is not the case in glass/PA6, where matrix plasticity is limited due to the presence of fibres and the local temperature is found to increase at most by +4°C. However, it is worth remarking how the local strain rate may be inhomogeneous and even span different orders of magnitude, in spite of the test speed being constant throughout deformation. This information is important for advanced material models incorporating the rate-dependent response.

description: We present a detailed analysis of the evolution of the rest-frame B-band morphology of K-selected galaxies with 0 < z < 2.5. This work is based on the K20 spectroscopic sample (Ks<20) located within the Chandra Deep Field South area, coupled with the public deep GOODS HST+ACSmulti-band optical imaging available in that field. Thanks to the spectroscopic completeness of this catalog reaching 94%, we can compare the morphological and spectroscopic properties of galaxies with unprecedented detail. Our morphological analysis includes visual inspection and automatic procedures using both parametric (e.g. the Sersic indices treated by the GALFIT and GASPHOT packages) and non-parametric (the Concentration, Asymmetry and clumpineSs, CAS) methods. Our analysis classifies the K20 galaxies as: 60/300 (20%, class 1) normal ellipticals/S0; 14/300 (4%, class 2) perturbed or peculiar ellipticals; 80/300 (27%, class 3) normal spirals; 48/300 (16%, class 4) perturbed or actively star-forming spirals; 98/300 (33%, class 5) irregulars. The evolution of the merging fraction is constrained up to z~2, by carefully accounting effects of morphological k-correction: both asymmetry criterion and pair statistic show an increasing merging fraction as a function of the redshift. We finally analyse the redshift-dependence of the effective radii for early- and late-type galaxies and find some mild evidence for a decrease with z of the early-type galaxy sizes, while disks and irregulars remain constant. Altogether, this analysis of the K20 sample indicates the large predominance of spirals and irregulars at 0.5

description: AbstractBackground: Antibiotic resistance in Klebsiella pneumoniae pose an increasing risk for human health worldwide.Objectives: A continuous monitoring the distribution of virulence and resistance-associated genes is required for early detection of successful K. pneumoniae lineages. In this study, whole genome sequences data was used to characterize phage-plasmids of K. pneumoniae isolated from different countries and its inhibitory compound was investigated for phage-plasmids. Methods: Whole genomes sequences of 15 genetically similar phage-plasmids of K. pneumoniae strains were selected according to BlastN analysis. Antibiotic resistance and virulence associated genes were screened by using ResFinder, PhageAI, PlasmidFinder, PHASTEST and PhageGE tools. Later on, whole genome sequences of phage-plasmids were analysed for a stable region in the genome by MAUVE analysis. The stable region encoding protein and its candidate inhibitor molecule was analysed to observe the interaction between protein and inhibitory compound by molecular docking studies. Results: Various antibiotic resistance genes involving Aminoglycosides and Beta-lactams were detected in screened 7 of 15 phage-plasmids. All the plasmids had Salmonella SSU5 prophage. Phylogenetic analysis results showed the phage-plasmid belonging to India or China. MAUVE analysis indicated that the region encoding Replication protein A were common stable region. Molecular docking studies proved an interaction occurring within Replication protein A and a derivate of Fabimycin.Conclusions: The analysis showed that Replication protein A could be a target site for new drug designing. Additionally, Fabimycin could be used to control both phage-plasmids and its host K. pneumonia, which could affect the severity and incidence of K. pneumoniae infections. Further studies in vitro and clinical studies could confirm present findings and also enhance our knowledge on phage-plasmids and new treatments against K. pneumoniae infections.

description: Necessary and sufficient stability and instability conditions are obtained for multi-term homogeneous linear fractional differential equations with three Caputo derivatives and constant coefficients. In both cases, fractional-order-dependent as well as fractional-order-independent characterisations of stability and instability properties are obtained, in terms of the coefficients of the multi-term fractional differential equation. The theoretical results are exemplified for the particular cases of the Basset and Bagley-Torvik equations, as well as for a multi-term fractional differential equation of an inextensible pendulum with fractional damping terms, and for a fractional harmonic oscillator.

description: Using a Wigner function based approach, we study the Renyi entropy of a subsystem $A$ of a system of Bosons interacting with a local repulsive potential. The full system is assumed to be in thermal equilibrium at a temperature $T$ and density $ρ$. For a ${\cal U}(N)$ symmetric model, we show that the Renyi entropy of the system in the large $N$ limit can be understood in terms of an effective non-interacting system with a spatially varying mean field potential, which has to be determined self consistently. The Renyi entropy is the sum of two terms: (a) Renyi entropy of this effective system and (b) the difference in thermal free energy between the effective system and the original translation invariant system, scaled by $T$. We determine the self consistent equation for this effective potential within a saddle point approximation. We use this formalism to look at one and two dimensional Bose gases on a lattice. In both cases, the potential profile is that of a square well, taking one value in the subsystem $A$ and a different value outside it. The potential varies in space near the boundary of the subsystem $A$ on the scale of density-density correlation length. The effect of interaction on the entanglement entropy density is determined by the ratio of the potential barrier to the temperature and peaks at an intermediate temperature, while the high and low temperature regimes are dominated by the non-interacting answer.

description: Leaner, more filigree, and resource-saving constructions are the development goal of the in the building industry. In reinforced concrete construction, a ultra-high strength concrete was developed to achieve these goals. Due to its use and requirements, this very pressure-resistant material is no longer only exposed to static loads. In applications such as wide-span bridges, machine foundations and wind turbines, the susceptibility to vibration is also significant. Research into the fatigue behavior of the new building material is therefore very important. In this article we will discuss the effect of heating up of high performance concretes under fatigue stress. The thesis is that warming up, which was already observed by several research groups, has an influence on the fatigue strength. Changes in the strength of the concrete or residual stresses generated by heating can lead to early failure. The aim is to find the reasons for the heating and the grade of influence on the fatigue strength. A systematic test program was developed to investigate the influencing parameters maximum stress level, frequency, and maximum grain size of the concrete. Thirty fatigue tests were carried out; the results will be presented here. The influence on the temperature increase as well as on the heating rate for the individual parameters will be discussed. The results show that all three discussed parameters have a significant influence on the temperature rise. Whereas the maximum temperature reached depends strongly on the frequency, the other two parameters mainly influence the heating rate.

description: The stray- and demagnetization tensor field for a homogeneously magnetized tetrahedron is found analytically. The tetrahedron is a special case of four triangular faces with constant magnetization-charge surface density, for which we also determine the tensor field. The tensor field is implemented in the open source micromagnetic and magnetostatic simulation framework MagTense and compared with the obtained magnetic field from an FEM solution, showing excellent agreement. This result is important for modeling magnetostatics in general and for micromagnetism in particular as the demagnetizing field of an arbitrary body discretized using conventional meshing techniques is significantly simplified with this approach.

description: In this paper we analyze the conditions under which increasing technical efficiency of water use in the agricultural sector might not reduce water demand and pressures on water ecosystems. Departing from this basic problem we discuss how policy measures performed to enhance water productivity in the agriculture might be transformed into effective alternatives to improve the conservation of water resources and then guarantee the successful implementation of the Water Framework Directive. A preference revelation model is presented in the third section of the paper and one empirical application to an irrigation district in southern Spain is used in the fourth section to discuss the effectiveness of water savings measures.
