    Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≀0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

    NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

    Full text link
    Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set. Please cite this data paper when using its data in publications. We also request that researchers and teachers inform us of how they are using these data

    NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

    Full text link
    Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data

    CMS - The Compact Muon Solenoid

    Full text link
    CMS is a general purpose proton-proton detector designed to run at the highest luminosity at the LHC. It is also well adapted for studies at the initially lower luminosities. The CMS Collaboration consists of over 1800 scientists and engineers from 151 institutes in 31 countries. The main design goals of CMS are: \begin{enumerate} \item a highly performant muon system, \item the best possible electromagnetic calorimeter \item high quality central tracking \item hermetic calorimetry \item a detector costing less than 475 MCHF. \end{enumerate} All detector sub-systems have started construction. Engineering Design Reviews of parts of these sub-systems have been successfully carried-out. These are held prior to granting authorization for purchase. The schedule for the LHC machine and the experiments has been revised and CMS will be ready for first collisions now expected in April 2006. \\\\ ~~~~∙\bullet Magnet \\ The detector (see Figure) will be built around a long (13~m) and large bore (ϕ\phi=5.9~m) high-field (4T) superconducting solenoid leading to a compact design for the muon spectrometer. The magnetic flux is returned through ≈\approx1.5~m of saturated iron yoke (1.8~T) instrumented with muon chambers. The construction of the magnet is well advanced. It will be tested on the surface in July 2004. Three of the five barrel yokes (YB) have been assembled in the surface building at Point 5. The assembly of the endcap yokes (YB) will start in April 2001. Four good lengths of Rutherford cable and three lengths of the insert (Rutherford cable co-extruded with pure aluminium), out of 21, have been produced. Each one has a length of 2.65km. The contracts for the winding machine have been placed. \\\\ ~~~~∙\bullet Inner Tracking \\ All high ptp_t muons, isolated electrons and charged hadrons, produced in the central rapidity region, are reconstructed with a momentum precision of Δpt/pt≈\Delta p_t / p_t \approx~0.005~+~0.15ptp_t (ptp_t in TeV). The high momentum precision is a direct consequence of the high magnetic field. The tracking volume is given by a cylinder of length 6~m and a diameter of 2.6~m. In order to deal with high track multiplicities tracking detectors with small cell sizes are used. Silicon microstrip detectors provide the required granularity and precision in the bulk of the tracking volume. Stereo information is provided by back-to-back microstrip detectors with strips at a small angle. Pixel detectors placed close to the interaction region improve the measurement of the track impact parameter and secondary vertices. High track finding efficiencies are achieved for isolated high ptp_t tracks. It is also fairly high for tracks in jets. \\ In June 2000 the LHCC approved the `All-Silicon Tracker' to be built in a single stage. The layout has been optimized with the removal of the central support tube. A pre-production comprising 200 detectors has been launched to exercise the automated production procedure. \\ The short bunch crossing time at the LHC (25ns) places challenging requirements on the readout electronics. Furthermore, the detectors and the read-out electronics have to withstand high levels of irradiation. A test in an LHC-like bunched beam was successfully carried out to test the functionality of the full electronics chain. Beam tests using electronics designed in the 0.25ÎŒ\mum technology have confirmed the expected performance. \\ Good progress is also being made on the electronics and mechanics of the pixel detectors. \\\\ ~~~~∙\bullet Muon System \\ Centrally produced muons are measured three times, in the inner tracker, after the coil and in the return flux. They are then identified and measured in four identical muon stations (MB) inserted in the return yoke. Special care has been taken to avoid pointing cracks and to maximize the geometric acceptance. Each muon station consists of twelve planes of aluminium drift tubes designed to give a muon vector in space, with 100~ÎŒ\mum precision in position and better than 1~mrad in direction. The four muon stations include RPC triggering planes that also identify the bunch crossing and enable a cut on the muon transverse momentum at the first trigger level. The endcap muon system also consists of four muon stations (ME). Each station consists of six planes of Cathode Strip Chambers. The chambers are arranged such that all muon tracks traverse four stations at all rapidities, including the transition region between the barrel and the endcaps. The last muon stations are after a total of ≄\geq~20λ\lambda of absorber so that only muons can reach them. The four muon stations lead to a redundant and robust muon system. \\ Facilities for mass production have been set up in the institutes participating in the construction of the muon chambers. One site, CIEMAT (Madrid), has built two pre-production drift tube prototype chambers using the final assembly tools and procedures. The commissioning of two more sites (Aachen and Legnaro, Padova) is nearly complete. Around thirty CSC chambers have been manufactured at Fermilab. Parts and tooling have been procured for the sites at PNPI, St. Petersburg and IHEP, Beijing. The procurement of parts for the barrel RPCs also commenced in 2000. Mass production of DTs and CSCs at various sites is expected to reach the final rates in 2001. \\ The combined (using the inner tracker as well as the muon chambers) muon momentum resolution is better than 5\% at 0.3 TeV in the central rapidity region ∣η∣<|\eta| < 2, and ≈\approx 10\% for ptp_t = 2 TeV. Low-momentum (pt<p_t < 100 GeV) muons are measured before the absorber with a precision of about 1.5\% up to a pseudorapidity of 2. \\\\ ~~~~∙\bullet Calorimetry \\ The coil radius is large enough to install essentially all the calorimetry inside and hence avoid the coil-electromagnetic calorimeter interference. A high precision electromagnetic calorimeter (ECAL) using lead tungstate (PbWO4_4) crystals has been chosen. Lead tungstate is a dense and relatively easy crystal to grow. \\ The scintillation light is detected by silicon avalanche photodiodes in the barrel region (EB, ∣η∣<|\eta|<1.48) and vacuum phototriodes in the endcap region (EE, 1.48<∣η∣<<|\eta|<3.0). The expected energy resolution is better than 0.6\% for electrons and photons with energies greater than 75 GeV. A preshower system (SE) is installed in front of the endcap calorimeter (1.65 â‰€âˆŁÎ·âˆŁâ‰€\leq|\eta|\leq 2.6). \\ The ECAL is followed by a copper/scintillator sampling hadronic calorimeter (HB, HE). The light is channelled by clear fibres fused to wave-length shifting fibres embedded in scintillator plates. The light is detected by photodetectors that can provide gain and operate in high axial magnetic fields (proximity focussed hybrid photodiodes). Coverage up to rapidities of 5.0 is provided by a steel/quartz fibre calorimeter (HF). The Cerenkov light emitted in the quartz fibres is detected by photomultipliers. \\ The pre-production (6000) of crystals from Russia has been completed. A contract for a further 30000 crystals has been placed in Russia. A breakthrough in crystal growing in Russia means that ingots can be grown of a diameter large enough for two crystals to be cut out. This will considerably increase the yield of crystals per oven. The crystal producers in China, using 28-fold pulling furnaces, have delivered 100 preliminary pre-production crystals that are being evaluated. The contract for the remaining 40000 crystals should be placed in 2001. The infrastructure at the centres where the crystals will be assembled into modules for installation has been set up. The photo-detectors, meeting the specifications, have been developed in collaboration with industry. The front-end chain consists of a preamplifier/range selector (FPPA), an ADC and a serializer/optical link. A 0.25ÎŒ\mum technology version of the serializer has been chosen. \\ Photon-pizero separation in the forward region requires a preshower detector (SE) in front of the crystals. Silicon sensors for the pre-shower detector, of the required quality, have now been produced in Russia, Taiwan and India. A large dynamic range preamplifier in a radiation-hard technology has been fabricated and successfully tested. \\ The absorber for the first HCAL half-barrel, HB-1 (18 wedges), was trial-assembled at Felguera, Spain. It was dismantled and the wedges have been delivered to CERN. The optics, scintillator plus embedded fibres, for more than half the barrel wedges have also been manufactured and delivered to CERN. The trial assembly of one endcap is nearing completion at the manufacturer, MZOR (Byelorussia). Optics manufacture for HE has started. The HF design was changed from bricks to 18 wedges per side. The fibre spacing was changed from 2.5mm to 5mm but the packing fraction is preserved. \\\\ ~~~~∙\bullet Trigger and Data Acquisition \\ The trigger and data acquisition consists of four parts: the front-end detector electronics, the calorimeter and muon first level trigger processors, the readout network and an on-line event filter system. The first two parts are synchronous and pipelined with a pipeline depth corresponding to ≈\approx3~ÎŒ\mus. The latter two are asynchronous and based on industry standard data communication components and commercial PCs. The resources that would have been required for a hardware second level trigger processors are invested in a high bandwidth (≈\approx~500~Gbit/s) readout network and in the event filter processing power (106^{6}-107^{7} MIPs), both of which are more suitable for upgrading as commercially available technology develops. \\ The CMS Level-1 trigger decision is based upon the presence of physics objects such as muons, photons, electrons, and jets, as well as global sums of Et_t and missing Et_t (to find neutrinos). The Level-1 Trigger Technical Design Report was submitted at the end of 2000. The DAQ system has to assemble the data from the triggered event, contained in about 500 front-end buffers (readout units), into a single processor in a ``farm'' for executing physics algorithms so that the input rate of 100 kHz is reduced to the 100 Hz of sustainable physics. A new Event Builder setup has been installed that consists of 64 Intel-PCs interconnected by two networks based on the most advanced technologies: a 64 port Gbit Ethernet (Foundry) and a 128-port Myrinet switch (Myricom). The setup will be used to evaluate all the software and hardware design options that will be considered for the TDR, destined for end-2002. \\\\ ~~~~∙\bullet Computing and Core Software \\ For complex systems, such as the CMS detector, an `object oriented' approach, implemented in C++, is now the choice of software developers. The move to this mainstream software technology will help to manage the process of change over the long lifetime of the experiment. C++ releases have been made of the functional prototypes of the software comprising the framework (CARF), the reconstruction program (ORCA), a basic GEANT4-based simulation program (OSCAR), and an interactive graphics toolkit (IGUANA). The OO technology has been used in the production of Level-1 and High Level Trigger simulation data. ORCA has been used for detector, trigger and physics studies. \\ The data storage, networking and processing power needed to analyse CMS data is well in excess of those of today's facilities. Technological advances will help to make the data analysis possible in a distributed environment, where physicists are scattered all over the world. The optimum mix of storage, networking and processing will change as technology develops. A multi-Tier model, similar to that developed by the MONARC project, underpinned by Grid Technology to provide efficient resource utilization and rapid turnaround time will be prototyped. \\\\ ~~~~∙\bullet Physics Reconstruction and Selection \\ With the construction phase starting in earnest, physics simulation work has begun to focus on the development of the eventual reconstruction code. As mentioned above this development is taking place using C++ and object-oriented methods. CMS has decided that the first priority is a full understanding and verification of the Higher Level Triggers (HLT). Since CMS does not employ distinct physical intelligences for the would-be Level-2 and Level-3 triggers, but only a single processor farm, the task of selecting events is intimately linked with that of reconstructing the associated detector information online. With this in mind, four ``Physics Reconstruction and Selection'' (PRS) groups were started (electron/photon, muon, jet/missing Et_t, and b/τ\tau vertexing) in April 1999. The aim of the groups is to develop the reconstruction and selection procedures (algorithms and software) starting from the output of the Level-1 trigger, and aiming ultimately at the full off-line reconstruction. During 2000, the four groups delivered the first algorithms that correspond to a reduction of the event rate after Level-1 by about a factor 10 using information from single CMS sub-detectors. The activity now continues as a new CMS project, the PRS project, which has close ties with the Computing and Trigger/DAQ projects. The PRS groups are now working on reconstructing physics objects using information from multiple CMS sub-detectors. \\\\ ~~~~∙\bullet Physics Performance \\ Although high luminosity is essential to cover the entire range of mechanisms of electroweak symmetry-breaking, the LHC machine will start at significantly lower luminosities (L~≀\leq1033^{33} cm−2^{-2} s−1^{-1}). The pixel detectors and the PbWO4_4 crystal electromagnetic calorimeter considerably enhance the discovery potential of CMS at low luminosities. \\ A Standard Model (SM) Higgs boson with mass between 95 and 150~GeV would be discovered via its two photon decay after an integrated luminosity of about 3×\times104^4 pb−1^{-1}. The same integrated luminosity gives a discovery range covering masses from 135 to 525~GeV in the four lepton (e or ÎŒ\mu) channel, with only a small gap in the coverage around 2 mW_W. An integrated luminosity of 105^5 pb−1^{-1} (taken at 1034^{34} cm−2 ^{-2}s−1^{-1} ) would allow discovery via these channels over the full range between 85 and 700 GeV. Tagging the events produced by WW- and ZZ-fusion by detecting characteristic forward jets, and using decay modes with larger branching ratios (H →\rightarrow WW →\rightarrow lÎœ\nujj, and H~→\rightarrow ZZ →\rightarrow lljj), should allow the discovery range for a SM Higgs boson to be extended up to 1~TeV for the same integrated luminosity. \\ The two photon and four lepton channels are also crucial for the discovery of a Higgs boson in the Minimal Supersymmetric Standard Model (MSSM). Various channels involving the tau lepton (h0^0, H 0^0, A 0^0 →\rightarrow τ\tau τ\tau, H±^\pm →\rightarrow τ\tau Îœ\nu) help to cover much of the remaining allowed (mA _{A}, tan ÎČ\beta) parameter space. Precise impact parameter measurements using the pixel detector play an important role here. \\ Many physics studies have been carried out in the context of supergravity models (SUGRA). A many-point scan of the gaugino / scalar mass parameter space has been conducted. Squarks and gluinos weighing up to 2~TeV can be detected using, as signature, events with one or more charged leptons, missing transverse energy and two or more jets. Sleptons weighing as much as 400~GeV can be found by looking for events without hadronic jets, but with lepton pairs and missing transverse energy with distinctive kinematic characteristics. Three-lepton states are particularly promising for the detection of charginos and neutralinos. In many cascade decays a heavier neutralino is produced that subsequently decays into the lightest one with the emission of a pair of charged leptons. For low to moderate values of tanÎČ\beta the spectrum of the di-lepton invariant masses shows a strikingly sharp end-point determined by the difference in neutralino masses. This feature can be used to select and almost fully reconstruct some events yielding e.g. the mass of the bottom squark. \\ The above studies of specific SUSY models indicate that it is possible to detect and measure a large fraction of the expected SUSY spectrum in CMS. Within the SUGRA models it should be possible to determine the fundamental parameters at the GUT scale. \\ The copious production of B mesons at LHC opens the way for significant measurements of CP violation effects in the B system. Using the Bs0^0_s and Bd0^0_d channels two of the angles in the unitarity triangle can be measured. Furthermore, by observing the time development of Bs0^0_s oscillations, the mixing parameter xs_s can be measured. \\ In addition to running as a proton-proton collider, LHC will be used to collide heavy ions at a centre of mass energy of 5.5~TeV per nucleon pair. A new form of deconfined hadronic matter, the quark-gluon plasma (QGP), should be formed at the resulting high energy densities (4-8 GeV/fm3^3). The formation of quark-gluon plasma in the heavy ion collisions is predicted to be signalled by a strong suppression of ΄â€Č\Upsilon' and ΄â€Čâ€Č\Upsilon'' production relative to ΄\Upsilon production when compared to pp collisions. The CMS detector is well suited to detect low momentum muons and reconstruct the ΄\Upsilon, ΄â€Č\Upsilon' and ΄â€Čâ€Č\Upsilon'' mesons produced. The good mass resolution (σ\sigma=37 MeV at ΄\Upsilon mass), afforded by the 4T field, enables the measurement of the suppression. Work has been carried out to obtain detailed understanding of the capabilities of CMS for heavy ion physics especially for signatures involving dimuon production, jet quenching and Z production. A detailed document has been prepared outlining the capabilities of CMS

    Notes for genera – Ascomycota

    Full text link
    Knowledge of the relationships and thus the classification of fungi, has developed rapidly with increasingly widespread use of molecular techniques, over the past 10--15 years, and continues to accelerate. Several genera have been found to be polyphyletic, and their generic concepts have subsequently been emended. New names have thus been introduced for species which are phylogenetically distinct from the type species of particular genera. The ending of the separate naming of morphs of the same species in 2011, has also caused changes in fungal generic names. In order to facilitate access to all important changes, it was desirable to compile these in a single document. The present article provides a list of generic names of Ascomycota (approximately 6500 accepted names published to the end of 2016), including those which are lichen-forming. Notes and summaries of the changes since the last edition of `Ainsworth Bisby's Dictionary of the Fungi' in 2008 are provided. The notes include the number of accepted species, classification, type species (with location of the type material), culture availability, life-styles, distribution, and selected publications that have appeared since 2008. This work is intended to provide the foundation for updating the ascomycete component of the ``Without prejudice list of generic names of Fungi'' published in 2013, which will be developed into a list of protected generic names. This will be subjected to the XIXth International Botanical Congress in Shenzhen in July 2017 agreeing to a modification in the rules relating to protected lists, and scrutiny by procedures determined by the Nomenclature Committee for Fungi (NCF). The previously invalidly published generic names Barriopsis, Collophora (as Collophorina), Cryomyces, Dematiopleospora, Heterospora (as Heterosporicola), Lithophila, Palmomyces (as Palmaria) and Saxomyces are validated, as are two previously invalid family names, Bartaliniaceae and Wiesneriomycetaceae. Four species of Lalaria, which were invalidly published are transferred to Taphrina and validated as new combinations. Catenomycopsis Tibell Constant. is reduced under Chaenothecopsis Vain., while Dichomera Cooke is reduced under Botryosphaeria Ces. De Not. (Art. 59)

    % ATLAS \\ \\ ATLAS is a general-purpose experiment for recording proton-proton collisions at LHC. The ATLAS collaboration consists of 144 participating institutions (June 1998) with more than 1750~physicists and engineers (700 from non-Member States). The detector design has been optimized to cover the largest possible range of LHC physics: searches for Higgs bosons and alternative schemes for the spontaneous symmetry-breaking mechanism; searches for supersymmetric particles, new gauge bosons, leptoquarks, and quark and lepton compositeness indicating extensions to the Standard Model and new physics beyond it; studies of the origin of CP violation via high-precision measurements of CP-violating B-decays; high-precision measurements of the third quark family such as the top-quark mass and decay properties, rare decays of B-hadrons, spectroscopy of rare B-hadrons, and Bs0 B ^0 _{s} -mixing. \\ \\The ATLAS dectector, shown in the Figure includes an inner tracking detector inside a 2~T~solenoid providing an axial field, electromagnetic and hadronic calorimeters outside the solenoid and in the forward regions, and barrel and end-cap air-core-toroid muon spectrometers. The precision measurements for photons, electrons, muons and hadrons, and identification of photons, electrons, muons, τ\tau-leptons and b-quark jets are performed over ∣η∣| \eta | < 2.5. The complete hadronic energy measurement extends over ∣η∣| \eta | < 4.7. \\ \\The inner tracking detector consists of straw drift tubes interleaved with transition radiators for robust pattern recognition and electron identification, and several layers of semiconductor strip and pixel detectors providing high-precision space points. \\ \\The e.m. calorimeter is a lead-Liquid Argon sampling calorimeter with an integrated preshower detector and a presampler layer immediately behind the cryostat wall for energy recovery. The end-cap hadronic calorimeters also use Liquid Argon technology, with copper absorber plates. The end-cap cryostats house the e.m., hadronic and forward calorimeters (tungsten-Liquid Argon sampling). The barrel hadronic calorimeter is an iron-scintillating tile sampling calorimeter with longitudinal tile geometry. \\ \\Air-core toroids are used for the muon spectrometer. Eight superconducting coils with warm voussoirs are used in the barrel region complemented with superconducting end-cap toroids in the forward regions. The toroids will be instrumented with Monitored Drift Tubes (Cathode Strip Chambers at large rapidity where there are high radiation levels). The muon trigger and second coordinate measurement for muon tracks are provide
