AbstractInorganic precipitation of aragonite is a common process within tropical carbonate environments. Across the Northwest Shelf of Australia (NWS) such precipitates were abundant in the late Pleistocene, whereas present-day sedimentation is dominated by calcitic bioclasts. This study presents sedimentological and geochemical analyses of core data retrieved from the upper 13 meters of IODP Site U1461 that provide a high-resolution sedimentary record of the last ~15 thousand years. Sediments that formed from 15 to 10.1 ka BP are aragonitic and characterised by small needles (<5 µm) and ooids. XRF elemental proxy data indicate that these sediments developed under arid conditions in which high marine alkalinity favoured carbonate precipitation. A pronounced change of XRF-proxy values around 10.1 ka BP indicates a transition to a more humid climate and elevated fluvial runoff. This climatic change coincides with a shelf-wide cessation of inorganic aragonite production and a switch to carbonate sedimentation dominated by skeletal calcite. High ocean water alkalinity due to an arid climate and low fluvial runoff therefore seems to be a prerequisite for the formation of shallow water aragonite-rich sediments on the NWS. These conditions are not necessarily synchronous to interglacial periods, but are linked to the regional hydrological cycle.

AbstractThe fruit fly species, Ceratitis rosa sensu stricto and Ceratitis quilicii, are sibling species restricted to the lowland and highland regions, respectively. Until recently, these sibling species were considered as allopatric populations of C. rosa with distinct bionomics. We used deep Next Generation Sequencing (NGS) technology on intact guts of individuals from the two sibling species to compare their transcriptional profiles and simultaneously understand gut microbiome and host molecular processes and identify distinguishing genetic differences between the two species. Since the genomes of both species had not been published previously, the transcriptomes were assembled de novo into transcripts. Microbe-specific transcript orthologs were separated from the assembly by filtering searches of the transcripts against microbe databases using OrthoMCL. We then used differential expression analysis of host-specific transcripts (i.e. those remaining after the microbe-specific transcripts had been removed) and microbe-specific transcripts from the two-sibling species to identify defining species-specific transcripts that were present in only one fruit fly species or the other, but not in both. In C. quilicii females, bacterial transcripts of Pectobacterium spp., Enterobacterium buttiauxella, Enterobacter cloacae and Klebsiella variicola were upregulated compared to the C. rosa s.s. females. Comparison of expression levels of the host transcripts revealed a heavier investment by C. quilicii (compared with C. rosa s.s.) in: immunity; energy production; cell proliferation; insecticide resistance; reproduction and proliferation; and redox reactions that are usually associated with responses to stress and degradation of fruit metabolites.

Published: December 2019

AbstractTelomere length and dynamics are central to understanding cell aging, genomic instability and cancer. Currently, there are limited guidelines for analyzing telomeric features in 3D using different cellular models. Image processing for telomere analysis is of increasing interest in many fields, however a lack of standardization can make comparisons and reproducibility an issue. Here we provide a user's guide for quantitative immunofluorescence microscopy of telomeres in interphase cells that covers image acquisition, processing and analysis. Strategies for determining telomere size and number are identified using normal human diploid Hs68 fibroblasts. We demonstrate how to accurately determine telomere number, length, volume, and degree of clustering using quantitative immunofluorescence. Using this workflow, we make the unexpected observation that hTERT-immortalized Hs68 cells with longer telomeres have fewer resolvable telomeres in interphase. Rigorous quantification indicates that this is due to telomeric clustering, leading to systematic underestimation of telomere number and overestimation of telomere size.

Antireflux-Operation im ersten Lebensjahr, wenn ja, wann und wie? Kontra OP
Authors: Rösch Wolfgang 
Published: December 2019

ZusammenfassungDas Management des vesikoureteralen Refluxes (VUR) im Säuglingsalter bleibt auch weiterhin ein überaus kontrovers diskutiertes Thema in der Kinderurologie. Hohe Spontanmaturationsraten selbst bei dilatierenden Refluxen von bis zu 45 %, der hohe Anteil an Jungen mit hohen Refluxgraden und oft assoziierter Nierenhypoplasie/Nierendysplasie von bis zu 30 % sowie die noch unreife Blasenfunktion kennzeichnen das Krankheitsbild in diesem Alter. Der Reflux per se hat in diesem Kontext eher an Bedeutung verloren. Umso erstaunlicher ist es, dass in letzter Zeit vermehrt Publikationen erscheinen, die eine endoskopische Therapie nicht nur als Alternative bei Durchbruchsinfektionen unter der Langzeittherapie, sondern auch als primäre Alternative zur Chemoprophylaxe empfehlen. Keine der bislang vorliegenden Metaanalysen konnte jedoch eine Evidenz für die Überlegenheit der endoskopischen Therapie gegenüber der Langzeitantibiose im Hinblick auf die Infekthäufigkeit oder die Entstehung neuer Parenchymnarben belegen. Demgegenüber stehen Nachteile dieser Methode wie die Notwendigkeit einer Narkose, die häufige Refluxpersistenz und das Obstruktionsrisiko sowohl postoperativ als auch im Langzeitverlauf. Die klassischen operativen Antireflux-Techniken sollten trotz moderner minimal invasiver Techniken aufgrund der hohen Spontanmaturationsrate und der in diesem Alter noch nicht abgeschlossenen Blasenfunktionsausreifung (sog. immature Blasenfunktion) auch weiterhin routinemäßig nicht zur Anwendung kommen und nur Einzelfällen vorbehalten bleiben

Authors: Hong Cierra S. , Black Collin S. , Ryan Sean P. , Seyler Thorsten M. 
Published: December 2019

AbstractOne of the most common reasons for failure of primary total knee arthroplasty and need for revision surgery is periprosthetic infection. Antibiotics are one of the mainstays of treatment to address prosthetic joint infections, but the route of administration and timing of delivery to optimize patient outcomes are debated. This article reviews the use and attributes of commonly used oral antibiotics, especially extended or long-term utilization, as prophylaxis and treatment for prosthetic joint infections in a primary or revision total knee arthroplasty, which include debridement, antibiotics, and implant retention, one-stage and two-stage exchange arthroplasty.
Mapping new translation practices into translation training

Published: December 2019

Abstract
Crowdsourcing and collaborative translation, activities emerging on the translation scene recently, are playing an
increasingly important role in the world of professional translation and in the localization industry. This article focuses on a
study carried out to analyze the perception of a group of translator trainees regarding these new translation practices. A total
of 20 undergraduate students participated in the research and were asked to perform a collaborative localization task using an
online collaborative platform. Data subjected to a quantitative and qualitative analysis suggest that online collaborative
translation tasks enhance students’ motivation towards collaborative translation and help consolidate their technical
knowledge about specific localization tools and files.
Nine-hundred-channel single-shot surface roughness measurement using hyperspectral interferometry
Authors: Reichold Tobias V , Ruiz Pablo D , Huntley Jonathan M 
Published: December 2019

Abstract
A recently developed hyperspectral interferometer has been applied, for the first time, to the single-shot measurement of surface roughness. Traditional optical surface profiling techniques, such as coherence scanning interferometry (CSI) or focus variation microscopy, require long scan times and mechanical motion of the imaging objectives, making them vulnerable to environmental disturbances and thus inappropriate as an embedded metrology tool for production. Hyperspectral interferometry (HSI) answers these problems by capturing spatial and spectral information to reconstruct the surface profile, from 900 locations measured in parallel, in a single shot. We report here measurement results with both HSI and CSI from 12 individual roughness samples taken from Rubert roughness gauges covering the roughness range

. Very good agreement was obtained for

values in the range 3–30 µm, where the HSI

values were mostly within a few per cent of (and at worst 24% away from) those measured by CSI

. An alternative measure of roughness, based on averaging the widths of the Fourier transform peak of the individual HSI interference signals, is shown to be a statistically reliable measure of local roughness in the medium to high roughness regime, i.e. for

values of 0.8 µm and above. The results thus demonstrate the technique’s potential for real-time surface quality inspection in manufacturing.

The β pore-forming toxins (β-PFTs) are cytotoxic proteins produced as soluble monomers, which cluster and oligomerize at the membrane of the target host cells. Their initial oligomeric state, the prepore, is not cytotoxic. The β-PFTs undergo a large structural transition to a second oligomeric state, the pore, which pierces the membrane of the host cell and is cytotoxic. Data from electrophysiology and vesicle permeabilization experiments have suggested the possibility of a correlation between the transition rate from prepore state to pore state and the levels of local crowding in the cluster of β-PFT oligomers. Nevertheless, to this date, visualization and understanding at the molecular level are missing. We have addressed this issue using a panel of Atomic Force Microscopy (AFM) techniques and simulations. We describe the mechanism by which the rates of formation of the transmembrane pores correlate with the local levels of crowding for the β-PFT lysenin and discuss possible biological and medical implications.
Electron density, temperature and the potential structure of spokes in HiPIMS

Published: December 2019

Abstract
In high power impulse magnetron sputtering (HiPIMS) bright plasma spots are observed during the discharge pulses that rotate with velocities in the order of 10 km s−1 in front of the target surface. It has proven very difficult to perform any quantitative measurements on these so-called spokes, which emerge stochastically during the build-up of each plasma pulse. In this paper, we propose a new time shift averaging method to perform measurements integrating over many discharge pulses, but without phase averaging of the spoke location, thus preserving the information of the spoke structure. This method is then applied to perform Langmuir probe measurements, employing magnetized probe theory to determine the plasma parameters inside the magnetic trap region of the discharge. Spokes are found to have a higher plasma density, electron temperature and plasma potential than the surrounding plasma. The electron density slowly rises at the leading edge of the spoke to a maximum value of about 1 × 1020 m−3 and then drops sharply at the trailing edge to 4 × 1019 m−3. The electron temperature rises from 2.1 eV outside the spoke to 3.4 eV at the trailing end of the spoke. A reversal of the plasma potential from about −7 V outside the spoke to values just above 0 V in a spoke is observed, as has been proposed in the literature.

AbstractA program that provides the task of classifying electric log data using machine learning methods is described. The program, after the training phase, allows one to automatically determine the composition of the rocks along the wellbore, which is necessary to ensure the technological process of uranium mining. The applied methods of data preprocessing, methods of forming a “floating window” of data and some results are briefly described. When using multilayer perceptron, the obtained average values of precision, recall, f1-score with recognition of 7 rock classes are 49%.At the same time, the developed program allows one to apply a wide range of classification algorithms, including Nearest-Neighbor (k-NN)), Logistic regression, Decision Tree, Support Vector Classifier, artificial neural network, busting, LSTM, etc. For example, when using XGBoost on same data with a change in the size of the floating window and the weight of individual classes (rocks), the indicated accuracy metric was up to 54%. The results of a comparative analysis of the mentioned methods on an extended data set will be presented in the next article of the authors.

It is shown that to detect them the approaches based on the analysis of the syntactic patterns; analysis of semantic information included in the text, and correlating it with the text corpus; crowd sourcing methods; identification of the patterns of user behavior in social networks; the consideration of the additional information etc., were applied. Good results can be achieved under certain conditions: an access to traffic social networks and other online news resources, opportunities to organize or to get results from crowd sourcing, etc., when there are the restrictions on these conditions the detection of destructive messages can be performed based on indirect signs. The results of the detection of destructive news in the corpus of news reports in Russian, posted on the websites of the Republic of Kazakhstan are shown.
Impact of electric vehicles on the cost-competitiveness of generation and storage technologies in the electricity system

Published: December 2019

Abstract
The increasing levels of variable renewable electricity (VRE) generation—such as wind and solar power—will create important opportunities for the charging of electric vehicle (EV) batteries during low-cost hours with a lot of VRE generation and for the discharge of EV batteries back to the grid (i.e. vehicle-to-grid; V2G) during high-cost hours. This study investigates how different EV charging strategies influence the cost-competitiveness of generation and storage technologies other than EV batteries in the electricity system, using a regional electricity system investment and dispatch model. The charging requirements of the EVs, which are used as an input to the optimisation model, are derived from the yearly driving patterns of 426 vehicles measured with global positioning system. The study is carried out for four regions in Europe with different conditions for wind, solar and hydro power generation. The results show that optimised EV charging with V2G can: (i) reduce investments in peak power capacity in all the regions investigated; (ii) reduce the need for short-term and long-term storage technologies other than EV batteries (i.e. stationary batteries and hydrogen storage); and (iii) stimulate increased shares of solar and wind power generation, as compared to direct charging in some regions (mainly Hungary). This study also shows that EV battery capacities as low as 30 kWh, which are connected to the grid only at their home location, can to a large extent contribute with flexibility to the electricity system in the way mentioned. The present study also investigates the influences of different shares of the fleet participating in V2G, and shows that the additional benefits for the electricity system level off when approximately 24% of the vehicle fleet participates in V2G.

Abstract
The infra-red limit of a planar static D3-brane in AdS

is a tensionless D3-brane at the anti-de Sitter horizon with dynamics governed by a strong-field limit of the Dirac–Born–Infeld action, analogous to that found from the Born–Infeld action by Bialynicki-Birula. As in that case, the field equations are those of an interacting 4D conformal invariant field theory with an

electromagnetic duality invariance, but the D3-brane origin makes these properties manifest. We also find an

-invariant action for these equations.
The procedure for determination of the dependence of the cost of insulation materials on their thermophysical characteristics
Authors: Gamayunova O S , Radaev A E , Petrichenko M R 
Published: December 2019

Abstract
Optimal insulation for the walls of the house is selected based on the material of construction and must meet several requirements. This article describes the method of justifying the dependence of the cost of heaters on their technical characteristics, based on a statistical analysis of price and thermophysical characteristics, used later in the development of optimization models for the selection and use of thermal insulation materials (heaters). To assess the quality of the resulting economic and mathematical model, the coefficient of determination was used. In order for the number of regressors (factors) not to affect the statistics of this coefficient, an adjusted coefficient of determination was also calculated, which gives a “penalty” for the factors included in the model.
