TL;DR: In this article, the advantages of combined anaerobic/aerobic treatment and the main post-treatment options currently in use are discussed, including the presentation of flowsheets and a comparison between various post-processing systems.
Abstract: This paper focuses on the post-treatment options for the anaerobic treatment of domestic wastewater. Initially, the main limitations of anaerobic systems regarding carbon, nutrients and pathogen removal are presented. In sequence, the advantages of combined anaerobic/aerobic treatment and the main post-treatment options currently in use are discussed, including the presentation of flowsheets and a comparison between various post-treatment systems. Lastly, the paper presents a review of emerging options and possible improvements of current post-treatment alternatives.

TL;DR: Bastin et al. as discussed by the authors estimated that tree planting for climate change mitigation could sequester 205 gigatonnes of carbon is approximately five times too large, which inflated soil organic carbon gains, failed to safeguard against warming from trees at high latitudes and elevations, and considered afforestation of savannas, grasslands, and shrublands to be restoration.
Abstract: Bastin et al.’s estimate (Reports, 5 July 2019, p. 76) that tree planting for climate change mitigation could sequester 205 gigatonnes of carbon is approximately five times too large. Their analysis inflated soil organic carbon gains, failed to safeguard against warming from trees at high latitudes and elevations, and considered afforestation of savannas, grasslands, and shrublands to be restoration.

TL;DR: An experiment to generate entangled states of D-dimensional quantum systems, qudits, by using transverse spatial correlations of two parametric down-converted photons to demonstrate that the generated states are entangled states.
Abstract: We report an experiment to generate entangled states of D-dimensional quantum systems, qudits, by using transverse spatial correlations of two parametric down-converted photons. Apertures with D slits in the arms of the twin photons define the qudit space. By manipulating the pump beam correctly, the twin photons will pass only by symmetrically opposite slits, generating entangled states between these different paths. Experimental results for qudits with D = 4 and 8 are shown. We demonstrate that the generated states are entangled states.

01 Apr 2008TL;DR: A methodology for characterizing and identifying user behaviors in online social networks is proposed and it is shown that attributes that stem from the user social interactions, in contrast to attributes relative to each individual user, are good discriminators and allow the identification of relevant user behaviors.
Abstract: Online social networks pose an interesting problem: how to best characterize the different classes of user behavior. Traditionally, user behavior characterization methods, based on user individual features, are not appropriate for online networking sites. In these environments, users interact with the site and with other users through a series of multiple interfaces that let them to upload and view content, choose friends, rank favorite content, subscribe to users and do many other interactions. Different interaction patterns can be observed for different groups of users. In this paper, we propose a methodology for characterizing and identifying user behaviors in online social networks. First, we crawled data from YouTube and used a clustering algorithm to group users that share similar behavioral pattern. Next, we have shown that attributes that stem from the user social interactions, in contrast to attributes relative to each individual user, are good discriminators and allow the identification of relevant user behaviors. Finally, we present and discuss experimental results of the use of proposed methodology. A set of useful profiles, derived from the analysis of the YouTube sample is presented. The identification of different classes of user behavior has the potential to improve, for instance, recommendation systems for advertisements in online social networks.

TL;DR: Polarized Raman spectra were obtained from a rope of aligned semiconducting single-wall nanotubes (SWNTs) in the vicinity of the D band and the G band based on group theory analysis and related theoretical predictions.
Abstract: Polarized Raman spectra were obtained from a rope of aligned semiconducting single-wall nanotubes (SWNTs) in the vicinity of the D band and the G band. Based on group theory analysis and related theoretical predictions, the G-band profile was deconvolved into four intrinsic SWNT components with the following symmetry assignments: 1549 cm(-1) [E-2(E-2g)], 1567 cm(-1) [A(A(1g)) + E-1(E-1g)], 1590 cm(-1) [A(A(1g)) + E-1(E-1g)] and 1607 cm(-1) [E-2(E-2g)]. The frequency shifts of the tangential G modes from the 2D graphitelike E-2g2 frequency are discussed in terms of the nanotube geometry.
