Denitriﬁcation losses in response to N fertiliser rates - a synthesis of high temporal resolution N2O, in-situ 15N2O and 15N2 measurements and fertiliser 15N recoveries in intensive sugarcane systems

Denitriﬁcation is a key process in the global nitrogen (N) cycle, causing both nitrous oxide (N2O) and dinitrogen (N2) emissions. However, estimates of seasonal denitriﬁcation losses (N2O+N2) are scarce, reﬂecting methodological diﬃculties in measuring soil-borne N2 emissions against the high atmospheric N2 background and challenges regarding their spatio-temporal upscaling. This study investigated N2O+N2 losses in response to N fertiliser rates (0, 100, 150, 200 and 250 kg N ha-1) on two intensively managed tropical sugarcane farms in Australia, by combining automated N2O monitoring, in-situ N2 and N2O measurements using the 15N gas ﬂux method and fertiliser 15N recoveries at harvest. Dynamic changes in the N2O/(N2O+N2) ratio ( < 0.01 to 0.768) were explained by ﬁtting generalised additive mixed models (GAMMs) with soil factors to upscale high temporal-resolution N2O data to daily N2 emissions over the season. Cumulative N2O+N2 losses ranged from 12 to 87 kg N ha-1, increasing non-linearly with increasing N fertiliser rates. Emissions of N2O+N2 accounted for 31–78% of fertiliser 15N losses and were dominated by environmentally benign N2 emissions. The contribution of denitriﬁcation to N fertiliser loss decreased with increasing N rates, suggesting increasing signiﬁcance of other N loss pathways including leaching and runoﬀ at higher N rates. This study delivers a blueprint approach to extrapolate denitriﬁcation measurements at both temporal and spatial scales, which can be applied in fertilised agroecosystems. Robust estimates of denitriﬁcation losses determined using this method will help to improve cropping system modelling approaches, advancing our understanding of the N cycle across scales.
Special Issue on SMI 2016 Color-aware surface registration

Shape registration is fundamental to 3D object acquisition; it is used to fuse scans from multiple views. Existing algorithms mainly utilize geometric information to determine alignment, but this typically results in noticeable misalignment of textures (i.e. surface colors) when using RGB-depth cameras. We address this problem using a novel approach to color-aware registration, which takes both color and geometry into consideration simultaneously. Color information is exploited throughout the pipeline to provide more effective sampling, correspondence and alignment, in particular for surfaces with detailed textures. Our method can furthermore tackle both rigid and non-rigid registration problems (arising, for example, due to small changes in the object during scanning, or camera distortions). We demonstrate that our approach produces signi ﬁ cantly better results than previous methods. & 2016 The Authors. Published by Elsevier Ltd.

(2017). Haematology and coagulation profiles in cats with congenital portosystemic shunts. Journal of Feline Medicine and Surgery, 19(12), 1290-1296.

Objective : To report the haematological parameters and coagulation times for cats with a congenital portosystemic shunt (CPSS) and the influence of surgical shunt attenuation on these parameters. To identify any association between prolongation in coagulation profiles and incidence of peri-operative haemorrhage. Methods : Retrospective clinical study using client owned cats with a CPSS. Signalment, shunt type (extrahepatic or intrahepatic), degree of shunt attenuation (complete or partial), haematological parameters, PT and aPTT test results and occurrence of any peri-operative clinical bleeding complications were recorded for cats undergoing surgical treatment of a CPSS at the Royal Veterinary College between 1994 and 2011. Results : Fourty-two cats were included. Thirty-six cats (87.5%) had an extrahepatic CPSS and six (14.3%) had an intrahepatic CPSS. Pre-operatively, mean cell volume (MCV) and mean cell haemoglobin (MCH) were below the reference interval in 32 (76.2%) and 31 (73.8%) cats

Russian Red Data Book Orchids: Taxonomic Diversity and Anthropogenic Drivers of Their Extinction in Regions †

: The research of drivers leading to plant extinction is a primary task in global biodiversity conservation. Despite Russia covering a large area, there is a lack of data on factors leading to plant extinction there, including orchids. We aimed to evaluate the anthropogenic drivers that threaten orchids included in the Russian Red Data Books. For this purpose, we generalized and systematized data on orchids included in all relevant (i.e., published during the last 10–11 years) regional Red Data Books available online on 31 December 2020. For each Red Data Book orchid, we identiﬁed threats, i.e., drivers leading to species extinction, according to the sections “Limiting factors” or “Limiting factors and threats” of the regional Red Data Books. We found the total taxonomic list of Red Data Book orchids in the analyzed regions of Russia. The similarity of the lists of orchid taxa in analyzed regions was established based on the Jaccard index. In regard to extinction drivers, we found which of them are the most serious threats to orchids in the regions of the Russian Federation. We believe that conducting a similar study for the whole array of threatened plants of Russia will provide highly valuable results demanded all over the world.

Sectoral labor supply , choice restrictions and functional form

In this paper we discuss a general framework for analyzing labor supply behavior in the presence of complicated budgetand quantity constraints of which some are unobserved. The individual’s labor supply decision is viewed as a choice from a set of discrete alternatives (jobs). These jobs are characterized by attributes such as hours of work, sector specific wages and other sector specific aspects of the jobs. We focus in particular on the theoretical justification of functional form assumptions and properties of the random components of the model. The labor supply model for married women is estimated on Norwegian data. Wage elasticities and the outcome of a tax reform analysis show that overall labor supply is moderately elastic, but these modest overall responses shadow for much stronger inter-sectoral changes. Our structural model, with a detailed specification of job opportunities, is compared empirically with a model in which the utility is approximated with a series expansion. It turns out that the performance of our model is at least as good as the labor supply model with flexible preferences. JEL classification: J22, C51.
Sediment resuspension and transport in Lake Michigan during the unstratified period

Instrumented moorings were deployed during the winter of 1994–95 at three depths (28, 58 and 101 m) in southern Lake Michigan. Storms during the observation period were not unusually severe, so the processes observed are typical of those that occur during an average winter. Time series observations of water temperature, beam attenuation coefficient (a measure of water transparency) and current velocity show that local resuspension of bottom sediment occurred frequently after the breakdown of the thermocline. Resuspension was most frequent close to the shore but was also observed at the 58 m station. Local resuspension did not occur at the 101 m station, but advection to the site of material resuspended at shallower sites was observed. These observations do not support the hypothesis proposed by previous investigators that local resuspension at depths of 100 m or greater occurs during the unstratified period. It is more likely that fine‐grained material resuspended by storm action in intermediate water depths (≈ 30–60 m) is transported into the deeper parts of the lake by the general lake circulation.
S.I. ABUDALFA EVALUATION OF SKELETONIZATION TECHNIQUES FOR 2D BINARY IMAGES

Abudalfa S.I. Evaluation of Skeletonization Techniques for 2D Binary Images. Abstract. In the realm of modern image processing, the emphasis often lies on engineering-based approaches rather than scientific solutions to address diverse practical problems. One prevalent task within this domain involves the skeletonization of binary images. Skeletonization is a powerful process for extracting the skeleton of objects located in digital binary images. This process is widely employed for automating many tasks in numerous fields such as pattern recognition, robot vision, animation, and image analysis. The existing skeletonization techniques are mainly based on three approaches: boundary erosion, distance coding, and Voronoi diagram for identifying an approximate skeleton. In this work, we present an empirical evaluation of a set of well-known techniques and report our findings. We specifically deal with computing skeletons in 2d binary images by selecting different approaches and evaluating their effectiveness. Visual evaluation is the primary method used to showcase the performance of selected skeletonization algorithms. Due to the absence of a definitive definition for the "true" skeleton of a digital object, accurately assessing the effectiveness of skeletonization algorithms poses a significant research challenge. The experimental results shown in this work illustrate the performance of the three main approaches in applying skeletonization with respect to different perspectives.
Geochronology and Petrogenesis of the Cretaceous Antampombato–Ambatovy Complex and Associated Dyke Swarm, Madagascar

The Antampombato–Ambatovy complex is the largest intrusion in the central–eastern part of the Cretaceous flood basalt province of Madagascar, with an exposed surface area of about 80 km. It has an Ar/Ar incremental heating age of 89 9 0 4Ma and a U–Pb age of 90 2Ma. The outcropping plutonic rocks range from dunite and wehrlite, through clinopyroxenite and gabbro, to sodic syenite. A dyke swarm cross-cutting some of the above lithologies (and the nearby Precambrian basement rocks) is formed of picritic basalts, alkali to transitional basalts, benmoreites and rhyolites; some of the latter are peralkaline. A few basaltic dykes have cumulate olivine textures, with up to 26 wt %MgO and 1200 ppm Ni, whereas others have characteristics more akin to those of primitive liquids (9 wt % MgO; Mg-number 0 61; 500 ppm Cr; 200 ppm Ni). These basalts have relatively high TiO2 (2 2 wt %) and total iron (14 wt % as Fe2O3), and moderate contents of Nb (10–11 ppm) and Zr (c. 100 ppm). Initial (at 90Ma) Srand Nd-isotope ratios of the clinopyroxenites and basalt dykes are 0 7030–0 7037 and 0 51290–0 51283, respectively. Syenites and peralkaline rhyolites have Srand Nd-isotope ratios of 0 7037– 0 7039 and 0 51271–0 51274, respectively. The data suggest derivation of the parental magmas from a time-integrated depleted mantle source, combined with small amounts of crustal contamination in the petrogenesis of the more evolved magmas. The isotopic compositions of the mafic–ultramafic rocks are most similar to those of the mid-ocean ridge basalt (MORB)-like igneous rocks of eastern Madagascar, and suggest the existence of an isotopically ‘ depleted’ component in the source of the entire Madagascar province, even though the Antampombato basalts are chemically unlike the lavas and dykes with the same depleted isotopic signature found in western Madagascar. If this depleted component is plume-related, this suggests that the plume has a broadly MORB-source mantle composition. The existence of isotopically more enriched magma types in the Madagascan province has several possible petrogenetic explanations, one of which could be the interaction of plume-related melts with the deep lithospheric mantle beneath the island.
Extreme NAT supersaturations in mountain wave ice PSCs: A clue to NAT formation

[1] There is evidence for the existence of nitric acid trihydrate (NAT) in polar stratospheric clouds (PSCs) and for its role in sedimentary denitrification enhancing chlorine-catalyzed ozone reduction. However, the scientific understanding of NAT formation mechanisms is vague. We show that high cooling rates in mountain waves, though causing only moderate NAT saturation ratios (SNAT ≲ 30) within supercooled ternary solution (STS) droplets, lead to SNAT ≳ 500 within the gas phase. Evidence from previous laboratory measurements suggests that such extreme supersaturations promote NAT deposition nucleation on ice or other solid surfaces, as long as they are not coated by STS. On the basis of airborne lidar PSC observations in three Arctic winters and a combined microphysical/optical model, we derive a simple parameterization for a NAT deposition nucleation rate which depends only on NAT supersaturation and temperature. The results indicate that deposition nucleation of NAT on ice surfaces exposed directly to the gas phase driven by extreme NAT supersaturations is able to explain the formation of NAT particle number densities up to ∼10 cm−3.
Artificial electron acceptors decouple archaeal methane oxidation from sulfate reduction

Long-term partners uncoupled Methane-munching archaea in marine sediments live closely coupled to sulfate-reducing bacteria in a syntrophic relationship. Surprisingly, however, these archaea do not necessarily need their bacterial partners to survive or grow. Scheller et al. performed stable isotope incubation experiments with deep-sea methane seep sediments (see the Perspective by Rotaru and Thamdrup). Several groups of methane-oxidizing archaea could use a range of soluble electron acceptors instead of coupling to active bacterial sulfate reduction. This decoupled pathway shows that methane-oxidizing archaea transfer electrons extracellularly and may even possess the capacity to respire iron and manganese minerals that are abundant in seafloor sediments. Science, this issue p. 703; see also p. 658 Artificial electron acceptors metabolically decouple deep-sea methanotrophic archaea from their syntrophic partner bacteria. [Also see Perspective by Rotaru and Thamdrup] The oxidation of methane with sulfate is an important microbial metabolism in the global carbon cycle. In marine methane seeps, this process is mediated by consortia of anaerobic methanotrophic archaea (ANME) that live in syntrophy with sulfate-reducing bacteria (SRB). The underlying interdependencies within this uncultured symbiotic partnership are poorly understood. We used a combination of rate measurements and single-cell stable isotope probing to demonstrate that ANME in deep-sea sediments can be catabolically and anabolically decoupled from their syntrophic SRB partners using soluble artificial oxidants. The ANME still sustain high rates of methane oxidation in the absence of sulfate as the terminal oxidant, lending support to the hypothesis that interspecies extracellular electron transfer is the syntrophic mechanism for the anaerobic oxidation of methane.
In-situ metagenomics: A platform for on-ﬁeld rapid sequencing and analysis of metagenomes in less than one day

We present a complete portable pipeline for sequencing and analysis of environmental metagenomes in less than a day. This unprecedented development was possible due to the conjunction of state-of-the art experimental and computational advances: a portable laboratory suitable for DNA extraction and sequencing with nanopore technology.The powerful metagenomic analysis pipeline SqueezeMeta, capable to provide a complete analysis in a few hours and using scarce computational resources. Finally, tools for the automatic inspection of the results via a graphical user interface, that can be coupled to a web server to allow remote visualization of data (SQMtools and SQMxplore). We tested the feasibility of our approach in the sequencing of the microbiota associated to volcanic rocks in La Palma, Canary Islands. Also, we did a two-day sampling campaign of marine waters in which the results obtained the ﬁrst day guided the experimental design of the second day. We demonstrate that it is possible to generate metagenomic information in less than one day, making it feasible to obtain taxonomic and functional proﬁles fast and eﬃciently, even in ﬁeld conditions. This capacity can be used in the further to perform real-time functional and taxonomic proﬁling of microbial communities in remote areas
HbA 1 c is associated with severity of obstructive sleep apnea hypopnea syndrome in nondiabetic men

Correspondence: Nikolaos Papanas Democritus University of Thrace, G Kondyli 22, Alexandroupolis 68100, Greece Tel +30 69 7754 4337 Fax +30 25 5107 4723 Email papanasnikos@yahoo.gr Abstract: The aim of this study was to examine the potential correlation of sleep characteristics with glucose metabolism in nondiabetic men with obstructive sleep apnea syndrome (OSAS). Included were 31 male patients (mean age 46.7 ± 11 years), recently diagnosed with OSAS by full polysomnography. There was a significant correlation of fasting glucose and glycosylated hemoglobin (HbA 1c ) levels with arousal index (P = 0.047 and P = 0.014, respectively). Moreover, HbA 1c levels were correlated with apnea hypopnea index (P = 0.009), a widely accepted marker of the severity of OSAS, and with percentage of sleep time with saturation of hemoglobin with oxygen as measured by pulse oximetry (SpO 2 ) 90% (t  90%) (P = 0.010). Finally, glucose and HbA 1c levels showed a significant negative correlation with average SpO 2 (P = 0.013 and P = 0.012, respectively) and, additionally, glucose levels with minimum SpO 2 (P = 0.027) during sleep. In conclusion, severity of OSAS among nondiabetic men is associated with increased HbA 1c levels and increased fasting glucose. Thus, severity of OSAS may be an additional marker of cardiovascular risk, as well as of future diabetes, in these subjects. However, further work is needed to confirm the clinical significance of these observations.
Atmospheric neutrino oscillations in IceCube-DeepCore

The IceCube Neutrino Observatory probes a breadth of particle physics through the DeepCore low-energy extension. DeepCore provides access to an abundance of earth-crossing neutrinos over much of the atmospheric cosmic-ray spectrum, from 5-100 GeV. Over such baselines, and having overcome the kinematic threshold for 𝜈 𝜏 charged current interactions, DeepCore provides unique multi-channel sensitivity to atmospheric oscillations (including 𝜈 𝜏 -appearance) with unprecedented statistical power. As a result, oscillations measurements from DeepCore are complementary to and competitive with those of long-baseline beam experiments. Here, recent and upcoming results from the current generation of IceCube oscillations analyses are summarised, including work on an 8+ year dataset which represents a milestone in high-statistics atmospheric mixing measurements.

Anomalous payload detection system by the combination of sparse-response deep belief network and support vector machine

This paper proposes how to detect malicious network data effectively by the combination of sparse-response deep belief network and support vector machine.The Sparse-response Deep belief networks (SR-DBN) is an efficient non-supervised leaning machine for learning feature representation of the data without redundancy and the Support Vector Machine is designed to develop a classifier, which has high generalization ability in the feature space, in a supervised manner. In this paper, the feature representation of anomalous payload is performed by Sparse-response Deep belief Networks(SR-DBN), while the classification of normal or abnormal payload is performed by Support Vector Machine. Simulations and experiments show that the proposed abnormal network-detecting system is higher detection rate than the multi-layer perceptron which has stacked auto-encoder.
Planning as Performance: The Murray-Darling Basin Plan.

The performance that is emerging following the release of the Guide to the proposed Basin Plan at 4 pm on Friday, 9 October 2010 has been scripted since the creation and passage of the Water Act 2007 (Cwlth) and the associated creation of the Murray–Darling Basin Authority (MDBA). 1 What is unfolding is a tableau that is the product of the structural determinism of its design.2 In this chapter, we first characterise certain features of the emerging performance following the release of the planning Guide. These features are then set within some of the structural determinants of the current policy/planning design. We then take a step back and address the question of relevance of framing planning as a ‘performance’. Arguments are then mounted for utilising this framing in a climate-change world—that world in which the enactment of the Basin Plan has to proceed and in which future cycles of planning will happen. We conclude with some suggested policy and practice initiatives that, from our choice of framing, seem warranted right now.3
