description: Hematite Fe$_2$O$_3$ seed layers are shown to constitute a pathway to prepare highly conductive transparent tin-doped indium oxide (ITO) thin films by room temperature magnetron sputtering. Conductivities of up to $σ= 3300\,{\rm S/cm}$ are observed. The improved conductivity is not restricted to the interface but related to an enhanced crystallization of the films, which proceeds in the rhombohedral phase.

description: Although beer is one of the most popular alcoholic beverages in the world, there is no specific legislation regarding contaminants, especially mycotoxins, for this product. The present manuscript reports the development and validation of an analytical methodology based on the QuEChERS approach, followed by quantification via UHPLC-MS/MS for the simultaneous determination of seventeen mycotoxins in beer. During the validation, amatrix effect was observed for 82% of the analytes. Linearity and recovery were evaluated using spiked blank samples, and the chosen methodology proved to be efficient for all analytes, with recoveries ranging from 71 to 118%, excepting ergonovine, for which recovery of 57% was achieved. Precision was estimated in terms of repeatability and reproducibility, with variations from 2.6 to 28.2% and 9.7 to 28.7%, respectively. The detection (LOD) and quantification (LOQ) limits, determined from the values of CCα and CCβ, ranged from 0.26 to 117 µgkg−1 and from 0.30 to 135 µgkg−1, respectively. Measurement uncertainties were based on the bottom-up methodology, with uncertainties ranging from 0.03 to 17 µgkg−1. Finally, thirty-eight beer samples, collected at the local market, were analysed, and 16 of them showed contamination by deoxynivalenol in concentrations ranging from 159 ± 26 µgkg−1 to 648 ± 106 µgkg−1.

description: Stability study of stationary solutions of the viscous Burgers equation using Fourier mode stability analysis for the stationary solutions u1 = D , where D is constant and u1 =u1(x),0≤x≤1, in two cases is analyzed. Firstly when the wave amplitude A is constant and secondly when the wave amplitude A is variable. In the case of constant amplitude, the results found to be: The solution u1 = D is always stable while the solution u1 = u1 (x) is conditionally stable. In the case of variable amplitude, it has been found that the solutions u1 = D and u1 = u1 (x) , 0 ≤ x ≤ 1 are conditionally stable.

subject: Australian sport

description: Over the past decade, there has been an increase in the reported cases of betting-motivated corruption (e.g., match-fixing, spot-fixing, and the misuse of inside information) within Australian sport. The increasing visibility of this type of corruption has raised commentary relating to the integrity of sport, both within Australia and internationally. Despite the growing threat to sport's integrity, research around betting-motivated corruption in Australian sport is still in its infancy. Currently, there is a need for research to investigate the application of regulation and anti-corruption concepts from other sectors to the sport context to further understand betting-motivated corruption prevention in Australian sport. To do this, a quantitative survey approach involving athletes and support staff (e.g. coaches, trainers, administrators) from sub-elite Australian rugby league and basketball was conducted over three interconnected studies: Study One explored the knowledge and beliefs of athletes and support staff in relation to the prevalence of betting-motivated corruption within their sport, their reasons for engaging in corruption, what would deter them, and what they believe would best prevent athletes and support staff from engaging in betting-motivated corruption; Study Two applied the Klockars integrity scale and explored attitudes of athletes and support staff towards four different betting-motivated corruption scenarios that could occur within their sport, and their perception of the culture around these unethical behaviours; and Study Three explored the 'code of silence' notion within the betting-motivated corruption context and identified key correlates of athletes' and support staff's reluctance to report, including perceptions of procedural justice and compliance, and the influence of organisational culture. Overall, the research contributes theoretical and practical considerations to inform academia, policymakers, and sport administrators concerned with the prevention of betting-motivated corruption in sport within Australia and internationally.

description: The value of the pair distribution function g(r) at contact (r = 0) in a quantum electron gas is determined by the scattering events between pairs of electrons with antiparallel spins. The theoretical results for g(0) as a function of the coupling strength r_s in the paramagnetic electron gas in dimensionality D=2 and 3, that have been obtained from the solution of the two-body scattering problem with a variety of effective scattering potentials embodying many-body effects, are compared with the results of many-body calculations in the ladder approximation and with quantum Monte Carlo data.

description: Social vulnerability evaluation is of important significance to analyzing risks of natural disasters to human society and economy. By using expert investigation and AHP method, 12 indicators from four aspects (population, economy, infrastructure and disaster prevention and mitigation capacity) are selected to assess social vulnerability to natural disasters on a county scale in Henan Province. The results show that the population vulnerability and economic vulnerability to natural disasters in the eastern region is generally higher than in the western region, while the areas with high infrastructure vulnerability are mainly located in the northwest; the disaster prevention and mitigation capacity in northwest is higher than in east and south, and this capacity of various districts is obviously higher than that of counties; in terms of the spatial pattern, social vulnerability to natural disasters is roughly higher in a belt from northeast to southwest, and lower on both sides of the belt. The results can provide scientific basis for disaster risk management and disaster prevention and mitigation planning in Henan Province.

description: Some secondary metabolites produced by fungi are carcinogenic, hepatotoxic, and/or cause birth defects in humans and animals. We developed and optimised bio-analytical tools for detection of metabolites, aflatoxins and evaluated the effectiveness of the methods in co-infected maize tissues. Isolate KSM012 (atoxigenic) demonstrated no peaks and no blue fluorescence on HPLC and TLC plates respectively confirming non-toxicity. AFB1 and AFB2 were produced by Isolate KSM015 in addition to AFG1 and AFG2, which is an indication of possible SBG morphotype. The limits of quantification and detection ranged from 0.02 to 35.81 µg/mL and 0.01–6.8 µg/mL, respectively. The best mass spectrum with lowest noise was obtained at 100% ACN and sterile water spiked with 0.1% formic acid at a flow rate of 0.3 mL/min. The positive ion mode with electrospray ionisation application exhibited better fragmentation for mycotoxins. In total 17 metabolites were detected by targeted and formula mass. KDVI maize line exhibited high fungal colonisation in comparison to GAF4 at equal co-infection ratio 50:50. AFB1 and AFG2 were remarkably higher in GAF4 in comparison to sensitive KDV1 (p ˂ 0.05). The detection limits, linearity and sensitivity showed the method developed was suitable for the determination of mycotoxin in comparisons to the guidelines of European Commission 657/EC 2002.

description: Higher-order topological insulators are newly proposed topological phases of matter, whose bulk topology manifests as localized modes at two- or higher-dimensional lower boundaries. In this work, we propose the twisted bilayer graphenes with large angles as higher-order topological insulators, hosting topological corner charges. At large commensurate angles, the intervalley scattering opens up the bulk gap and the corner states occur at half filling. Based on both first-principles calculations and analytic analysis, we show the striking results that the emergence of the corner states do not depend on the choice of the specific angles as long as the underlying symmetries are intact. Our results show that the twisted bilayer graphene can serve as a robust candidate material of two-dimensional higher-order topological insulator.

The traditional analysis of the statistics of velocity increments by means of structure functions or probability density functions is replaced by a new method which is based on the theory of stochastic Markovian processes. It gives access to a more complete characterization by means of joint probabilities of finding velocity increments at several scales. Based on this more precise method our results call in question the concept of universality.

description: Expo is the Universal Exhibition that the city of Milan hosted from May to October, 2015, under the theme: “Feeding the Planet, Energy for Life”. Nevertheless, if the big event is important for awakening the world's interest and attracting investment, much attention is dedicated to the “ Expo after Expo” phase, with the aim to keep alive the public discussion on the these crucial issues even by the end of the exposition period. In summary, what will be the legacies of Expo 2015? This work takes an innovative approach to this question by analysing Twitter data focusing on the “after Expo” period. More specifically, the analysis of the distribution in the Twitter sphere of a set of food-related topics (right to food, sustainability, food losses as examples) is performed. Results can represent an opportunity to understand if the discussion of the global challenges linked to the theme of Expo Milano 2015 can also bring lasting benefits in terms of public awareness.

description: We develop a product-differentiated model where the product space is a network defined as a set of varieties (nodes) linked by their degrees of substitutability (edges). We also locate consumers into this network, so that the location of each consumer (node) corresponds to her “ideal” variety. We show that, even though prices need not to be strategic complements, there exists a unique Nash equilibrium in the price game among firms. Equilibrium prices are determined by both firms’ sign-alternating Bonacich centralities and the average willingness to pay across consumers. They both hinge on the network structure of the firm-product space. We also investigate how local product differentiation and the spatial discount factor affect the equilibrium prices. We show that these effects non-trivially depend on the network structure. In particular, we find that, in a star-shaped network, the firm located in the star node does not always enjoy higher monopoly power than the peripheral firms.
Radiative feedback from an early X-ray background

description: The first generation of stars (commonly known as population III) are expected to form in low-mass protogalaxies in which molecular hydrogen is the dominant coolant. Radiation from these stars will rapidly build up an extragalactic ultraviolet background capable of photodissociating H2, and it is widely believed that this background will suppress further star formation in low-mass systems. However, star formation will also produce an extragalactic X-ray background. This X-ray background, by increasing the fractional ionization of protogalactic gas, promotes H2 formation and reduces the effectiveness of ultraviolet feedback. In this paper, we examine which of these backgrounds has the dominant effect. Using a simple model for the growth of the UV and X-ray backgrounds, together with a detailed one-dimensional model of protogalactic chemical evolution, we examine the effects of the X-ray backgrounds produced by a number of likely source models. We show that in several cases, the resulting X-ray background is strong enough to offset UV photodissociation in large H2-cooled protogalaxies. On the other hand, small protogalaxies (those with virial temperatures T_vir < 2000K) remain dominated by the UV background in all of the models we examine. We also briefly investigate the effects of the X-ray background upon the thermal and chemical evolution of the diffuse IGM.

description: We present STEREO observations within 1500 proton gyroradii of 12 interplanetary shocks, with long-duration burst mode electric field acquisition by S/WAVES enabling observation of the evolution of waves throughout the entire ramp of interplanetary shocks. The shocks are low Mach number ($M_{f} \sim $1--5), quasi-perpendicular ($θ_{Bn} \geq 45^{\circ}$), with beta ($β$) $\sim $0.2--1.8. High variability in frequency, amplitude, and wave mode is observed upstream, downstream, and in shock ramps. Observations in every region include ion acoustic-like waves, electron cyclotron drift instability driven waves, electrostatic solitary waves, and high frequency whistler mode waves. We also show for the first time the existence of "dispersive" electrostatic waves with frequencies in the ion acoustic range and the first observations of electron cyclotron drift instability (ECDI) driven waves at interplanetary shocks. Large amplitude waves are bursty and seen in all three regions with amplitudes from $\sim$5 to $>$ 200 mV/m. All wave modes are more commonly observed downstream of the shocks than upstream of them, usually within $\sim$ 63000 km ($\sim 1500 ρ_{gi}$) of the ramp.

description: Microscopic multiphase flows have gained broad interest due to their capability to transfer processes into new operational windows and achieving significant process intensification. However, the hydrodynamic behavior of Taylor droplets is not yet entirely understood. In this work, we introduce a model to determine the excess velocity of Taylor droplets in square microchannels. This velocity difference between the droplet and the total superficial velocity of the flow has a direct influence on the droplet residence time and is linked to the pressure drop. Since the droplet does not occupy the entire channel cross section, it enables the continuous phase to bypass the droplet through the corners. A consideration of the continuity equation generally relates the excess velocity to the mean flow velocity. We base the quantification of the bypass flow on a correlation for the droplet cap deformation from its static shape. The cap deformation reveals the forces of the flowing liquids exerted onto the interface and allows estimating the local driving pressure gradient for the bypass flow. The characterizing parameters are identified as the bypass length, the wall film thickness, the viscosity ratio between both phases and the Ca-number. The proposed model is adapted with a stochastic, metaheuristic optimization approach based on high-speed camera measurements. In addition, our model is successfully verified with published empirical data.

Kumepagurus

description: Kumepagurus n. gen.
[new Japanese name: Kumejima-doukutsu-yadokari-zoku]
 Type species. Kumepagurus cavernicolus n. sp., by present designation.
 Diagnosis. Gills biserial, 13 pairs (2 arthrobranchs above bases of third maxilliped to fourth pereopods and 1 pleurobranch on each body wall of fifth to seventh thoracic somites). Rostrum roundly triangular. Ocular acicles simple. Third maxilliped with crista dentata consisting of moderately spaced, unequal teeth; no accessory tooth. Right cheliped massive, chela operculate; dactylus articulating obliquely with palm. Fourth pereopod simple, with propodal rasp consisting of single row of corneous scales; no preungual process. Male with medium, coiled, laterally oriented sexual tube on coxa of right fifth pereopod; left coxa with short sexual tube, directed posteriorly, tapering distally to slender, acute tip. Male with left third to fifth pleopods. Female characters unknown. Pleon dextrally twisted. Sixth pleonal tergite not strongly calcified. Telson with terminal margins strongly oblique.
 Remarks. Only a single male specimen was available for study, and thus the female diagnostic characters remain unknown. This new genus resembles Pylopaguropsis Alcock, 1905, in the possession of 13 pairs of biserial gills and the operculate right chela. In addition, the tip of the fixed finger of the left chela bears two terminal corneous spines in this new species, a character shared only with Pylopaguropsis species among pagurid genera (Asakura 2000). However, Kumepagurus n. gen. is readily distinguished from Pylopaguropsis by the possession of prominent sexual tubes in males. Furthermore, the absence of an accessory tooth on the third maxilliped and the simple fourth pereopod, also immediately differentiate the new genus from Pylopaguropsis. There are no other pagurid genera characterized by the combination of the 13 pairs of biserial gills and the possession of welldeveloped sexual tubes.
 Etymology. Named after the type locality, Kume Island. Gender: masculine.

description: (abridged version) We report on ten type I X-ray bursts from GX 17+2 in data obtained with the RXTE/PCA in 1996--2000. Three bursts were short in duration (~10 s), whereas the others lasted for ~6-25 min. Five of the long bursts showed evidence for radius expansion of the neutron star photosphere. No correlations o f the burst properties with respect to the persistent X-ray spectral properties are seen, suggesting no correlation with inferred persistent mass accretion rate. The presence of short bursts in GX 17+2 (and similar bright X-ray sources) is not accounted for in the current X-ray bursts theories at the high mass accretion rates encountered in these sources. We find that in contrast to previous suggestions the persistent black-body emission does NOT arise from the same site as the burst emission. The black-body component of the persistent emission is consistent with arising in an expanded boundary layer, as indicated by recent theoretical work. The total persistent flux just before and after the radius expansion bursts is inferred to be up to a factor of 2 higher than the net peak flux of the burst. If both the burst and persistent emission are radiated isotropically, this would imply that the persistent emission is up to a factor of 2 higher than the Eddington luminosity. This is unlikely and we suggest that the persistent luminosity is close to the Eddington luminosity and that the burst emission is (highly) anisotropic. Assuming that the net burst peak fluxes equal the Eddington limit, applying standard burst parameters (1.4 M_sun neutron star, cosmic composition, electron scattering opacity appropriate for high temperatures), and taking into account gravitational redshift and spectral hardening, we derive a distance to GX 17+2 of ~8 kpc, with an uncertainty of up to ~30%.

description: Perceptual features (PFs) have been used with great success in tasks such as transfer learning, style transfer, and super-resolution. However, the efficacy of PFs as key source of information for learning generative models is not well studied. We investigate here the use of PFs in the context of learning implicit generative models through moment matching (MM). More specifically, we propose a new effective MM approach that learns implicit generative models by performing mean and covariance matching of features extracted from pretrained ConvNets. Our proposed approach improves upon existing MM methods by: (1) breaking away from the problematic min/max game of adversarial learning; (2) avoiding online learning of kernel functions; and (3) being efficient with respect to both number of used moments and required minibatch size. Our experimental results demonstrate that, due to the expressiveness of PFs from pretrained deep ConvNets, our method achieves state-of-the-art results for challenging benchmarks.

description: Agricultural activities within the city boundaries have a long history in both developed and developing countries. Especially in developing countries these activities contribute to food security and the mitigation of malnutrition (food grown for home consumption). They generate additional income and contribute to recreation, environmental health as well as social interaction. In this paper, a broad approach of Urban AgriCulture is used, which includes the production of crops in urban and peri-urban areas and ranges in developed countries from allotment gardens (Schrebergarten) over community gardens (Urban Gardening) to semi-entrepreneurial self-harvest farms and fully commercialized agriculture (Urban Farming). Citizens seek to make a shift from traditional to new (sustainable) forms of food supply. From this evolves a demand for urban spaces that can be used agriculturally. The way how these citizens’ initiatives can be supported and their contribution to a resilient and sustainable urban food system increasingly attracts attention. This paper presents an empirical case study on Urban AgriCulture initiatives in the Bonn-Rhein-Sieg region (Germany). Urban AgriCulture is still a niche movement with the potential to contribute more significantly to urban development and constitute a pillar of urban quality of life.

description: We calculate the full frequency spectral density of voltage fluctuations in a Single Electron Transistor (SET), used as an electrometer biased above the Coulomb threshold so that the current through the SET is carried by sequential tunnel events. We consider both a normal state SET and a superconducting SET. The whole spectrum from low frequency telegraph noise to quantum noise at frequencies comparable to the SET charging energy $(E_{C}/\hbar)$, and high frequency Nyquist noise is described. We take the energy exchange between the SET and the measured system into account using a real-time diagrammatic Keldysh technique. The voltage fluctuations determine the back-action of the SET onto the measured system and we specifically discuss the case of superconducting charge qubit read-out and measuring the so-called Coulomb staircase of a single Cooper pair box.
