Where does water come from and go to in cities? Integrated database for 243 Argentine urban centers

Las ciudades dependen de distintos ecosistemas que les proveen servicios. Para el caso de la provisión de agua potable y la disposición de aguas servidas en las ciudades argentinas, el reconocimiento de esto aún es incompleto y fragmentado. Aquí presentamos la primera base de datos que mapea y clasifica las fuentes de suministro de agua y destinos de los efluentes de todas las ciudades argentinas con más 20000 habitantes (en 2010). A partir de reportes existentes, noticias periodísticas e información satelital se registraron en 243 ciudades los puntos de toma y vertido de aguas, junto a otra infraestructura asociada. Se encontró que 30.5, 17.5 y 12.6% de la población se abastece sólo de grandes ríos transfronterizos, agua subterránea y ríos y arroyosinternos, respectivamente, con 25.2% abastecido por fuentes mixtas. Las ciudades que están conectadas a las redes públicas de saneamiento recurren para su disposición sobre todo a ríos y arroyos internos (26.6%); sin embargo, de la población urbana que no está conectada a la red cloacal, una proporción elevada dispone sus vertidos en acuíferos libres. La mayoría de las ciudades argentinas no devuelven las aguas de saneamiento al mismo sistema que las provee, y predominan los trasvases desde fuentes subterráneas hacia ríos y arroyos internos. La base de datos evidencia la contrastante ?presión efluente? (relación población/caudal del sistemareceptor) entre ciudades vinculadas a grandes ríos (e.g., la cuenca del Paraná, con 273 habitantes.m-3.s-1) y a cuencas internas (e.g., la cuenca de Mar Chiquita, con 16141 habitantes.m-3.s-1). Esta base de datos, abierta para la consulta y actualización, visibiliza la conexión espacial e hidrológica entre las ciudades y la red hidrográfica, y contribuye a mejorar la seguridad hídrica y a priorizar los esfuerzos de protección de los ecosistemas acuáticos que la garantizan desde todos los niveles de gestión.Where does water come from and go to in cities? Integrated database for 243 Argentine urban centers. Cities depend on different ecosystems that provide them with services. In the case of water supply and effluent disposal in Argentine cities, its recognition is still incomplete and fragmented. Here is presented a first database that maps and classifies the water supply sources and effluent destinations of all Argentine cities >20000 inhabitants (in 2010). Utilizing existing reports, journalistic news and satellite information, water intake and discharge points were recorded, along with other associated infrastructure in 243 cities. It was found that 30.5, 17.5 and 12.6% of the population is exclusively supplied by large transboundary rivers, groundwater and internal rivers and streams, respectively, with 25.2% supplied by mixed sources. The cities that are connected to the public sanitation networks resort mainly to internal rivers and streams (26.6%) for their disposal; however, of the urban population that is not connected to the sewage network, a high proportion discharges into free aquifers. Most Argentine cities do not return sewage water to the same system that supplies it, predominantly transfers from underground sources to internal rivers and streams. The database evidences the contrasting ‘effluent pressure’ (population/flow rate of the receiving system) between cities linked to large rivers (e.g., Paraná basin, 273 inhabitants.m-3.s-1) and internal basins (e.g., Mar Chiquita, 16141 inhabitants.m-3.s-1). This database, open for consultation and updating, makes visible the spatial and hydrological connection between cities and the hydrographic network, helping to improve water security and prioritize efforts to protect aquatic ecosystems that guarantee it from all levels of management.Fil: Llanes, Ana Laura.

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

Searches for the ZγZ\gamma decay mode of the Higgs boson and for new high-mass resonances in pppp collisions at s=13\sqrt{s} = 13 TeV with the ATLAS detector

International audienceThis article presents searches for the Zγ decay of the Higgs boson and for narrow high-mass resonances decaying to Zγ, exploiting Z boson decays to pairs of electrons or muons. The data analysis uses 36.1 fb$^{−1}$ of pp collisions at $\sqrt{s}=13$ recorded by the ATLAS detector at the CERN Large Hadron Collider. The data are found to be consistent with the expected Standard Model background. The observed (expected — assuming Standard Model pp → H → Zγ production and decay) upper limit on the production cross section times the branching ratio for pp → H → Zγ is 6.6. (5.2) times the Standard Model prediction at the 95% confidence level for a Higgs boson mass of 125.09 GeV. In addition, upper limits are set on the production cross section times the branching ratio as a function of the mass of a narrow resonance between 250 GeV and 2.4 TeV, assuming spin-0 resonances produced via gluon-gluon fusion, and spin-2 resonances produced via gluon-gluon or quark-antiquark initial states. For high-mass spin-0 resonances, the observed (expected) limits vary between 88 fb (61 fb) and 2.8 fb (2.7 fb) for the mass range from 250 GeV to 2.4 TeV at the 95% confidence level

Search for direct top squark pair production in final states with two leptons in s=13\sqrt{s} = 13 TeV pppp collisions with the ATLAS detector

International audienceThe results of a search for direct pair production of top squarks in events with two opposite-charge leptons (electrons or muons) are reported, using $36.1~\hbox {fb}^{-1}$ of integrated luminosity from proton–proton collisions at $\sqrt{s}=13$ TeV collected by the ATLAS detector at the Large Hadron Collider. To cover a range of mass differences between the top squark $\tilde{t}$ and lighter supersymmetric particles, four possible decay modes of the top squark are targeted with dedicated selections: the decay $\tilde{t} \rightarrow b \tilde{\chi }_{1}^{\pm }$ into a b-quark and the lightest chargino with $\tilde{\chi }_{1}^{\pm } \rightarrow W \tilde{\chi }_{1}^{0}$ , the decay $\tilde{t} \rightarrow t \tilde{\chi }_{1}^{0}$ into an on-shell top quark and the lightest neutralino, the three-body decay $\tilde{t} \rightarrow b W \tilde{\chi }_{1}^{0}$ and the four-body decay $\tilde{t} \rightarrow b \ell \nu \tilde{\chi }_{1}^{0}$ . No significant excess of events is observed above the Standard Model background for any selection, and limits on top squarks are set as a function of the $\tilde{t}$ and $\tilde{\chi }_{1}^{0}$ masses. The results exclude at 95% confidence level $\tilde{t}$ masses up to about 720 GeV, extending the exclusion region of supersymmetric parameter space covered by previous searches

Study of the material of the ATLAS inner detector for Run 2 of the LHC

International audienceThe ATLAS inner detector comprises three different sub-detectors: the pixel detector, the silicon strip tracker, and the transition-radiation drift-tube tracker. The Insertable B-Layer, a new innermost pixel layer, was installed during the shutdown period in 2014, together with modifications to the layout of the cables and support structures of the existing pixel detector. The material in the inner detector is studied with several methods, using a low-luminosity √s=13 TeV pp collision sample corresponding to around 2.0 nb−1 collected in 2015 with the ATLAS experiment at the LHC. In this paper, the material within the innermost barrel region is studied using reconstructed hadronic interaction and photon conversion vertices. For the forward rapidity region, the material is probed by a measurement of the efficiency with which single tracks reconstructed from pixel detector hits alone can be extended with hits on the track in the strip layers. The results of these studies have been taken into account in an improved description of the material in the ATLAS inner detector simulation, resulting in a reduction in the uncertainties associated with the charged-particle reconstruction efficiency determined from simulation
