Asymmetric supernova remnants generated by Galactic, massive runaway stars

After the death of a runaway massive star, its supernova shock wave interacts with the bow shocks produced by its defunct progenitor, and may lose energy, momentum, and its spherical symmetry before expanding into the local interstellar medium (ISM). We investigate whether the initial mass and space velocity of these progenitors can be associated with asymmetric supernova remnants. We run hydrodynamical models of supernovae exploding in the pre-shaped medium of moving Galactic core-collapse progenitors. We find that bow shocks that accumulate more than about 1.5 Mo generate asymmetric remnants. The shock wave first collides with these bow shocks 160-750 yr after the supernova, and the collision lasts until 830-4900 yr. The shock wave is then located 1.35-5 pc from the center of the explosion, and it expands freely into the ISM, whereas in the opposite direction it is channelled into the region of undisturbed wind material. This applies to an initially 20 Mo progenitor moving with velocity 20 km/s and to our initially 40 Mo progenitor. These remnants generate mixing of ISM gas, stellar wind and supernova ejecta that is particularly important upstream from the center of the explosion. Their lightcurves are dominated by emission from optically-thin cooling and by X-ray emission of the shocked ISM gas. We find that these remnants are likely to be observed in the [OIII] lambda 5007 spectral line emission or in the soft energy-band of X-rays. Finally, we discuss our results in the context of observed Galactic supernova remnants such as 3C391 and the Cygnus Loop.
Serological and molecular characterization of hepatitis B virus infection in chronic kidney disease patients from Rio de Janeiro, Brazil

Chronic kidney disease (CKD) patients undergoing hemodialysis (HD) are more vulnerable to blood-borne viral infections due to frequent invasive procedures. Hepatitis B virus (HBV) infection in this cohort of patients has been a matter of concern worldwide. The objective of this cross-sectional study was to evaluate the frequency of serological markers for hepatitis B, and the occurrence of overt and occult HBV infection (OBI) and its molecular characterization in serum samples from 644 CKD patients in HD units located in Rio de Janeiro, Brazil, from 2013 to 2017. HBV DNA was investigated in HBsAg reactive and “anti-HBc alone” samples to determine infecting genotypes and genetic relatedness between sequences. The prevalence of serological markers HBsAg+, anti-HBc alone, anti-HBc+/anti-HBs+, anti-HBs+, anti-HBc/anti-HBs/HBsAg were 5.9%, 2.8%, 30.7%, 26.6%, 34.0%, respectively. HBV DNA was detected in 39.5% (15/38) of the HBsAg+ and in 5/18 (27.8%) of the “anti-HBc alone” individuals, indicating a high prevalence of OBI within this group. We found a higher prevalence of HBV/A1 (65%), followed by HBV/D3 (20%), and HBV/A2 (15%). Bayesian MCC tree with a highly supported clade, genetic distance comparison, and identical nucleotide sequences suggested a nosocomial spread of HBV in some units. The high prevalence of HBV infection and low number of individuals immune to infection reinforces the need for vaccination in this group. The presence of closely related strains in the same HD unit reinforces the importance of continuous improvement of safety control measures and laboratory surveillance of serological markers to prevent the risk of infection and transmission of HBV.
THE CORUNDUM + TOURMALINE NODULES RELATED TO HYDROTHERMAL ALTERATION OF SPODUMENE IN THE NANPING No. 31 PEGMATITE DYKE, FUJIAN PROVINCE, SOUTHEASTERN CHINA

The Nanping No. 31 pegmatite is a spodumene-subtype LCT granitic pegmatite in southeastern China. Spodumene mainly occurs as rock-forming mineral in the quartz – coarse albite – spodumene zone (zone III) and the quartz – spodumene – amblygonite zone (zone IV). Various alteration-induced phenomena were observed in spodumene. Spodumene in zone III is usually altered along its {110} cleavages to networks of albite + muscovite, resulting from a replacement of spodumene by an alkaline fluid, which likely begins by Na metasomatism. Extensive alteration of spodumene in zone IV to quartz and muscovite veinlets is related to replacement by K+- and H+-rich fluid. However, alteration by strongly acid fluids also affected spodumene, leading to formation of fine-grained white mica in zones III and IV. In this paper, we focus on the occurrence of nodules of corundum + tourmaline, which are typically restricted to the aggregates of white mica in zone IV. Fibrous corundum and radial tourmaline signify a hydrothermal origin. Their textural relationship with secondary muscovite suggest a close genetic relation with the latter. The corundum + tourmaline nodules arise by alteration of the secondary muscovite by late B-, Mg- and Fe-rich fluids.
Secondary organic aerosols production in pre and post-industrial-like environments : the impact of biogenic and anthropogenic emissions on climate

Anthropogenic emissions (i.e. particles and trace gases) are constantly rising since the industrialization inducing wide changes on the climate of the Earth system, on local degradation of air quality and impactAnthropogenic emissions (i.e. particles and trace gases) are constantly rising since the industrialization inducing wide changes on the climate of the Earth system, on local degradation of air quality and impacting human health. The aim of the SAPIENTIAM project is to identify new mechanisms that allow to describe the preindustrial atmospheric status and its change as consequence of the human activities emission related to industrialization. 
Secondary organic particles are produced in the atmosphere by the reactions of biogenic volatile organic compounds in presence of nitrogen oxides (NOx) and sulfate (SO2). One of the main uncertainties of the role of particles on the changes of climate and air quality, is related to the impact of anthropogenic emissions on their concentrations and properties. 
In order to define new mechanisms of atmospheric particle formation in pre-industrial and post-industrial conditions, a laboratory experiment will be carried out at the Harvard Environmental Chamber (outgoing phase). In detail, the pristine pre-industrial-like environment’s atmosphere will be simulated in the chamber considering first only the biogenic emissions and, then, adding the contribution of anthropogenic emissions such as NOx and SO2. Recent studies highlighted the important role played by the ocean as potential source of atmospheric particle, but field observations to confirm this hypothesis are quite rare.  Another aim of this project is to verify the results obtained by the laboratory experiments in a field campaign in marine environment representing an innovative post-industrial-like site, where the interaction between biogenic and anthropogenic emissions are poorly explored (return phase at the University of Chieti-Pescara, Ud'A)

Decomposing Residential Self-Selection via a Life-Course Perspective

We propose a decomposition of residential self-selection by understanding the process of its formation. We take a life-course perspective and postulate that locations experienced early in life can have a lasting effect on our locational preferences later in life. In other words, what was experienced spatially is a key factor contributing to our residential self-selection, and our preferences in residential locations are formed long before the onset of our self-selection. We further hypothesize that this prior-location influence is modified by the duration and recency of the prior stay. Using a dataset collected in the New York City Area, we estimated a series of multinomial logit models to test these hypotheses. The results confirm the prior-location influence and demonstrate that this precedes residential self-selection and is impacted by its own properties such as duration and recency. Furthermore, the analysis separating child-bearing households from non-child-bearing households shows an interaction between prior-location influence and the presence of children.

A High Efficient Coding Method for Bayer Image

We propose a visual lossless compression scheme of mosaic image based on wavelet sub-band substitute.The encoder is designed to separate green components from red and blue components.Firstly,full resolution green image demosiced from raw mosaic image is produced and green mosaic image is near-losslessly coded by LOCO-I scheme designed by Weinberger.After a wavelet transform,the red and blue points are compressed only on compression low frequency sub-band.In the decoder,the high frequency sub-bands of red and blue mosaic component are taken from the high frequency sub-bands of full resolution green image which locate at the same position as raw red or blue mosaic image,so we can reconstruct raw red or blue mosaic image based on decoded low frequency sub-bands of red and blue mosaic component.Compared with JPEG2000,the performance of proposed method is apparently better for low complexity level and high compression ratio.

Fungal Cytochrome P450 Monooxygenases: Their Distribution, Structure, Functions, Family Expansion, and Evolutionary Origin

Cytochrome P450 (CYP) monooxygenase superfamily contributes a broad array of biological functions in living organisms. In fungi, CYPs play diverse and pivotal roles in versatile metabolism and fungal adaptation to specific ecological niches. In this report, CYPomes in the 47 genomes of fungi belong to the phyla Ascomycota, Basidiomycota, Chytridiomycota, and Zygomycota have been studied. The comparison of fungal CYPomes suggests that generally fungi possess abundant CYPs belonging to a variety of families with the two global families CYP51 and CYP61, indicating individuation of CYPomes during the evolution of fungi. Fungal CYPs show highly conserved characteristic motifs, but very low overall sequence similarities. The characteristic motifs of fungal CYPs are distinguishable from those of CYPs in animals, plants, and especially archaea and bacteria. The four representative motifs contribute to the general function of CYPs. Fungal CYP51s and CYP61s can be used as the models for the substrate recognition sites analysis. The CYP proteins are clustered into 15 clades and the phylogenetic analyses suggest that the wide variety of fungal CYPs has mainly arisen from gene duplication. Two large duplication events might have been associated with the booming of Ascomycota and Basidiomycota. In addition, horizontal gene transfer also contributes to the diversification of fungal CYPs. Finally, a possible evolutionary scenario for fungal CYPs along with fungal divergences is proposed. Our results provide the fundamental information for a better understanding of CYP distribution, structure and function, and new insights into the evolutionary events of fungal CYPs along with the evolution of fungi.
Computation of road geometry parameters using mobile LiDAR system

Abstract The continuous assessment of road geometry parameters is important for road condition analysis and the required maintenance work. Mobile LiDAR system (MLS) is being frequently used for roadway data collection due to its capability of accurate and dense three-dimensional data acquisition at highway speed. The high-precision road terrain obtained in terms of the point cloud is used as primary data for road geometry parameters computation. An automatic method is proposed in this research paper for computing road width, road centerline, longitudinal slope and cross slope. Initially, an equation of the line as a best-fit polynomial is used to represent road boundary as connected piecewise linear segments. Further road width and road centerline are computed. MLS data points at road boundary and road centerline are used to compute road slopes. The root mean square error of 2.1%, 2.5%, and 2.2% for longitudinal slope, cross slope (left lane), and cross slope (right lane), respectively were obtained. Proposed method works efficiently on the MLS data points of complex and heterogeneous roadway scene.
