He will take over from Michel Della Negra, who has been CMS spokesperson since its formalization in 1992. Three distinguished physicists stood as candidates for this election: Dan Green from Fermilab, programme manager of the US-CMS collaboration and coordinator of the CMS Hadron Calorimeter project; Jim Virdee from Imperial College London and CERN, deputy spokesperson of CMS since 1993; Gigi Rolandi from the University of Trieste and CERN, ex-Aleph spokesperson and currently involved in the preparations of the physics analyses to be done with CMS. On the early evening of 21 June, 141 of the 142 members of the CMS collaboration board, some represented by proxies, took part in a secret ballot.

    Guido Tonelli has been elected as the next CMS spokesperson. He will take over from Jim Virdee on January 1, 2010, and will head the collaboration through the first crucial year of data-taking. Guido Tonelli, CMS spokesperson-elect, into the CMS cavern. "It will be very tough and there will be enormous pressure," explains Guido Tonelli, CMS spokesperson-elect. "It will be the first time that CMS will run for a whole year so it is important to go through the checklist to be able to take good quality data." Tonelli, who is currently CMS Deputy spokesperson, will take over from Jim Virdee on January 1, 2010 – only a few months into CMS’s first full year of data-taking. "The collisions will probably be different to our expectations. So it’s going to take the effort of the entire collaboration worldwide to be ready for this new phase." Born in Italy, Tonelli originally studied at the University of Pisa, where he is now a Professo...

    Full Text Available Ellis-van Creveld syndrome also known as chondroectodermal dysplasia is a rare genetic disorder of the skeletal dysplasia type, first described by Richard WS Ellis and Simon van Creveld in 1940. The syndrome manifests with several skeletal anomalies, oral mucosal and dental anomalies, congenital cardiac defects, nail dysplasia and polydactyly of one or both limbs. It is caused by mutation of EVC1 and EVC2 genes located in a head-to-head configuration on chromosome 4p16, which has been identified as the causative. The EVC phenotype is variable and affects multiple organs. The presence of oral mucosal and dental alterations, like the presence of numerous frenulum, oligodontia, bellshaped anterior teeth, hypoplastic erupted teeth with high-caries index, will confirm the diagnosis of Ellis-van Creveld syndrome and hence its importance to dentists.

    Ellis-van Creveld (EVC) (OMIM # 225500) syndrome is a rare skeletal dysplasia disorder transmitted by autosomal recessive inheritance. The diagnosis is made based on phenotypic characteristics such as chondrodysplasia, heart defects and polydactyly. The prognosis depends mainly on the severity of the disease, diagnosis and comprehensive management of the condition. To describe a patient diagnosed with EVC syndrome. Newborn diagnosed with EVC syndrome who presented dysmorphic facies, shortened long bones, rhizomelic shortening, small hands, brachydactyly, single transverse palmar crease, postaxial polydactyly in the upper limbs, bilateral preaxial polysyndactyly in lower limbs and hypoplastic nails, complex heart defects and narrow thorax. The evolution was unfavorable; the patient died 8 weeks after birth from complications due to heart defects. EVC syndrome is rare and unknown; therefore, it is important to spread its characteristics within the pediatric community, emphasizing that it affects multiple organ systems and requires a multidisciplinary approach to treat individually each patient, to provide genetic and reproductive counseling to couples and to give information regarding child development expectations.

    The CMS experiment collects and analyzes large amounts of data coming from high energy particle collisions produced by the Large Hadron Collider (LHC) at CERN. This involves a huge amount of real and simulated data processing that needs to be handled in batch-oriented platforms. The CMS Global Pool of computing resources provide +100K dedicated CPU cores and another 50K to 100K CPU cores from opportunistic resources for these kind of tasks and even though production and event processing analysis workflows are already managed by existing tools, there is still a lack of support to submit final stage condor-like analysis jobs familiar to Tier-3 or local Computing Facilities users into these distributed resources in an integrated (with other CMS services) and friendly way. CMS Connect is a set of computing tools and services designed to augment existing services in the CMS Physics community focusing on these kind of condor analysis jobs. It is based on the CI-Connect platform developed by the Open Science Grid and uses the CMS GlideInWMS infrastructure to transparently plug CMS global grid resources into a virtual pool accessed via a single submission machine. This paper describes the specific developments and deployment of CMS Connect beyond the CI-Connect platform in order to integrate the service with CMS specific needs, including specific Site submission, accounting of jobs and automated reporting to standard CMS monitoring resources in an effortless way to their users.

  20. Ellis-Van Creveld syndrome

    2007-06-01

    Full Text Available Abstract Ellis-van Creveld syndrome (EVC is a chondral and ectodermal dysplasia characterized by short ribs, polydactyly, growth retardation, and ectodermal and heart defects. It is a rare disease with approximately 150 cases reported worldwide. The exact prevalence is unknown, but the syndrome seems more common among the Amish community. Prenatal abnormalities (that may be detected by ultrasound examination include narrow thorax, shortening of long bones, hexadactyly and cardiac defects. After birth, cardinal features are short stature, short ribs, polydactyly, and dysplastic fingernails and teeth. Heart defects, especially abnormalities of atrial septation, occur in about 60% of cases. Cognitive and motor development is normal. This rare condition is inherited as an autosomal recessive trait with variable expression. Mutations of the EVC1 and EVC2 genes, located in a head to head configuration on chromosome 4p16, have been identified as causative. EVC belongs to the short rib-polydactyly group (SRP and these SRPs, especially type III (Verma-Naumoff syndrome, are discussed in the prenatal differential diagnosis. Postnatally, the essential differential diagnoses include Jeune dystrophy, McKusick-Kaufman syndrome and Weyers syndrome. The management of EVC is multidisciplinary. Management during the neonatal period is mostly symptomatic, involving treatment of the respiratory distress due to narrow chest and heart failure. Orthopedic follow-up is required to manage the bones deformities. Professional dental care should be considered for management of the oral manifestations. Prognosis is linked to the respiratory difficulties in the first months of life due to thoracic narrowness and possible heart defects. Prognosis of the final body height is difficult to predict.

    The story of Ellis-van Creveld syndrome is one of serendipity. By chance, Simon van Creveld and Richard Ellis purportedly met on a train and combined their independently encountered patients with short stature, dental anomalies and polydactyly into one landmark publication in 1940. They included a patient used in work published previously by Rustin McIntosh without naming McIntosh as a coauthor. This patient was followed radiologically by Caffey for nearly two decades. In 1964, Victor McKusick felt compelled to investigate a brief report in an obscure pharmaceutical journal on an unusual geographic cluster of short-statured Amish patients in Pennsylvania. This review highlights the lives of the individuals involved in the discovery of Ellis-van Creveld syndrome in their historic context.

    Pierluigi Campana begins his 3-year tenure as LHCb spokesperson this June. As the new voice for the collaboration, Campana will lead the experiment through what should prove to be a very exciting phase.   Pierluigi Campana, from the Istituto Nazionale di Fisica Nucleare in Frascati, has been with the collaboration since 2000 and was heavily involved in the construction of the muon chamber of the LHCb detector. He replaces Andrei Golutvin, from Imperial College London and Russia’s Institute for Theoretical and Experimental Physics. “Leading such a large collaboration is not an easy task,” says Campana. While he will rely heavily upon the work of his predecessor, he plans on leaving his own mark on the position: “One of the main goals of my job will be to enhance the spirit of collaboration between the different institutes within our experiment.” LHCb plays a key role in the search for new physics. The experiment is conducting a very precise search...

    Working under great time pressure towards a common goal in gradual steps can sometimes cause us to forget to take a step back, and celebrate what marvels have been achieved. A general need was felt within CMS to expand the recognition for our young scientists that made outstanding, well recognized and creative contributions to CMS, which served to significantly advance the performance of CMS as a complete and powerful experiment. Therefore, the Collaboration Board endorsed in March 2009 a proposal from the CB Chair and Advisory Group to award each year the newly created "CMS Achievement Award" to fourteen graduate students and postdocs that made exceptional contributions to the Tracker, ECAL, HCAL and Muon subdetectors as well as the TriDAS project, the Commissioning of CMS and the Offline Software and Computing projects. It was also agreed that there was a need to go back in time, and retroactively attribute awards for the years 2007 and 2008 when CMS went from a bare cavern to a detect...

    After having retraced the entire Standard Model up to the Top, the CMS collaboration is ready to go further and continue the success of what Guido Tonelli – its spokesperson – defines as a ‘magic year’. Things evolve fast at CMS, but scientists have taken up the challenge and are ready for the future.   ‘Enthusiasm’ is the word that best describes the feeling one gets when talking to Guido Tonelli. “In just a few months we have rediscovered the Standard Model and have gone even further by producing new results for cross-sections, placing new limits on the creation of heavy masses, making studies on the excited states of quarks, and seeking new resonances. We could not have expected so much such a short space of time. It’s fantastic”, he says. “We went through the learning phase very smoothly. Our detector was very quickly ready to do real physics and we were able to start to produce results almost ...

    CMS, one of the two gigantic international collaborations running experiments at the LHC, has recently appointed its new management. The new spokesperson and his two deputies are well aware of the pressure associated with holding such high positions during such a historic time for particle physics. Although their focus is on the Higgs, they anticipate that other areas of CMS’ multi-purpose research programme might become equally as intriguing this year.   With around 4,300 active members representing every continent and the task of uncovering some of the deepest mysteries of the Universe, CMS is constantly under the spotlight. The pressure is on to ensure the high performance of the detector while providing solutions for extremely accurate but quick data analysis. “The LHC machine is setting the pace for CMS,” explains Joseph Incandela from UC Santa Barbara/CERN, the new CMS spokesperson. “The 2012 run will most probably go to a higher energy and inten...

    Most recent CMS data related to the high-density QCD are presented for pp and PbPb collisions at 2.76 TeV and pPb collisions at 5.02 TeV. The PbPb collision is essential to understand collective behavior and the final-state effects for the detailed characteristics of hot, dense partonic matter, whereas the pPb collision provides the critical information on the initial-state effects including the modification of the parton distribution function in cold nuclei. This paper highlights some of recent heavy-ion related results from CMS.

  13. Spokespersons in media campaigns of non-profit organizations

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available The subject of this research is how spokespersons can be used in campaigns of non-profit organizations, with a goal to increase their visibility and gain public support. Namely, many companies employ celebrities for their media campaigns as protagonists and promoters of brand values. With their appearance and engagement, celebrities transfer part of their image and credibility to the brand, which widens and enriches the field of associations which brands trigger in consumers' conscience. Non-profit organizations could get similar benefits out of these campaigns. In a society where there is a certain level of fascination with celebrities, i.e. celebrity culture, their influence can be used not only to attract attention to the goods, but also to ideas. The goal of the paper is to show how spokespersons can influence behavior and attitudes of the public by participating in media campaigns, and also the important aspects of choosing a spokesperson. The paper is supposed to be a starting point for practitioners,so they can design creative ideas based on this technique on the non-profit organizations market, especially in Serbia.

    Full Text Available Ellis-van Creveld syndrome is a rare autosomal-recessive disorder characterized by short limbs, post-axial polydactyly, ectodermal dysplasia, edentulous mandibular incisor region, absence of mucobuccal fold, congenitally missing teeth, slight serrations of the alveolar ridge and multiple small alveolar notches. The clinical report not only describes the classical oral and dental manifestations of Ellis-van Creveld syndrome but also presents unusual findings such as single-rooted and funnel-shaped primary first molars, single conical roots of primary second molars and taurodontisum, which must be considered in the differential diagnostic criteria to avoid misdiagnosis of syndromes. The article also discusses the differential diagnosis and preventive and therapeutic oral health care for these patients. The management of Ellis-van Creveld syndrome is multidisciplinary and, therefore, the oral health care provider should get updated with latest knowledge for timely referral to prevent the patient from further complications of heart defect and bony deformity.

  1. Havelock Ellis's literary criticism, canon formation, and the heterosexual Shakespeare.

    Science.gov (United States)

    Radel, Nicholas F

    2009-01-01

    Famous as the author of an early full-length scientific study of sexual inversion or homosexuality, English sexologist Havelock Ellis was also a literary critic responsible for initiating publication of the famous Mermaid Series of "The Best of Plays of the Old Dramatists" in the late-nineteenth century. Personally editing the first volume of plays by Christopher Marlowe and a later collection by tragedian John Ford, Ellis associated these playwrights here and in his scientific work, Sexual Inversion, with ideas about normative and so-called abnormal sexualities at the start of the twentieth century. Ellis, thus, helped give expression to a literary canon of early English dramatists in which modern, anachronistic ideas about sexual subjectivity play a part. While this article does not claim that Ellis was the necessary source for later criticism, it shows how, over the whole of the twentieth century, Shakespeare's priority in the literary canon came to be posited at least in part on his apparent sexual normality in contrast with a supposedly homosexual Christopher Marlowe and other playwrights such as Ford or Francis Beaumont and John Fletcher associated with varying degrees of sexual difference.

    We describe a relatively new effort within CMS to converge on a set of web based tools, using state of the art industry techniques, to engage with the CMS offline computing system. CMS collaborators require tools to monitor various components of the computing system and interact with the system itself. The current state of the various CMS web tools is described along side current planned developments. The CMS collaboration comprises of nearly 3000 people from all over the world. As well as its collaborators, its computing resources are spread all over globe and are accessed via the LHC grid to run analysis, large scale production and data transfer tasks. Due to the distributed nature of collaborators effective provision of collaborative tools is essential to maximise physics exploitation of the CMS experiment, especially when the size of the CMS data set is considered. CMS has chosen to provide such tools over the world wide web as a top level service, enabling all members of the collaboration to interact with the various offline computing components. Traditionally web interfaces have been added in HEP experiments as an afterthought. In the CMS offline we have decided to put web interfaces, and the development of a common CMS web framework, on an equal footing with the rest of the offline development. Tools exist within CMS to transfer and catalogue data (PhEDEx and DBS/DLS), run Monte Carlo production (ProdAgent) and submit analysis (CRAB). Effective human interfaces to these systems are required for users with different agendas and practical knowledge of the systems to effectively use the CMS computing system. The CMS web tools project aims to provide a consistent interface to all these tools

  8. Celebrity endorsements versus created spokespersons in advertising: a survey among students

    Directory of Open Access Journals (Sweden)

    2011-08-01

    Full Text Available In this study the use of endorsements in advertising was investigated.  Endorsements can either be in the form of a celebrity acting as a spokesperson for an organisation or the organisation can create a spokesperson to act as an endorser.  The problem that faces marketers is that little scientific proof exists if students perceive celebrity endorsements and creative spokespersons differently with regard to their expertise and trustworthiness.  The aim of this study was to determine the attitudes of respondents with regard to expertise, trustworthiness and attractiveness of created spokesperson and celebrity endorsements in advertisements. This knowledge will provide marketing professionals with the strategic advantage of how and when to make use of an endorser. Ohanian’s (1990 measurement scale of perceived expertise, trustworthiness and attractiveness was adopted in a self-administrative questionnaire for this article.  Respondents (n=185 were exposed to six visual images of endorsers namely:  three celebrities and three created spokespersons.  It was found that attractiveness should not be used as a factor when comparing created endorsers with celebrity endorsers.  The respondents perceived both endorsement applications as highly credible and professionals need to consider each application’s advantages and disadvantages when deciding which application will be more effective for their advertising strategy.  In the long term the organisation might find it more cost effective to create its own spokesperson due to the risk of possible characteristics changes or negative associations of celebrity endorsers.  Revoking advertisements after celebrity endorsers have received negative publicity or changed character can lead to great financial losses.  Created endorsers, on the other hand, provide the organisation with greater control and the ability to change to adapt to the organisations market and advertising needs.

  15. CMS workload management

    International Nuclear Information System (INIS)

    Spiga, D.

    2007-01-01

    From september 2007 the LHC accelerator will start its activity and CMS, one of the four experiments, will begin to take data. The CMS computing model is based on the the Grid paradigm where data is deployed and accessed on a number of geographically distributed computing centers. In addition to real data events, a large number of simulated ones will be produced in a similar, distributed manner. Both real and simulated data will be analyzed by physicist, at an expected rate of 100000 jobs per day submitted to the Grid infrastructure. In order to reach these goals, CMS is developing two tools for the workload management (plus a set of services): ProdAgent and CRAB. The ProdAgent deals with MonteCarlo production system: it creates and configures jobs, interacts with the Framework, merges outputs to a reasonable filesize and publishes the simulated data back into CMS data bookkeeping and data location services. CRAB (Cms Remote Analysis Builder) is the tool deployed ad hoc by CMS to access those remote data. CRAB allows a generic user, without specific knowledge of the Grid infrastructure, to access data and perform its analysis as simply as in a local environment. CRAB takes care to interact with all Data Management services, from data discovery and location to output file management. An overview of the current implementation of the components of the CMS workload management is presented in this work

    To impart hands-on training in physics analysis, CMS experiment initiated the concept of CMS Data Analysis School (CMSDAS). It was born over three years ago at the LPC (LHC Physics Centre), Fermilab and is based on earlier workshops held at the LPC and CLEO Experiment. As CMS transitioned from construction to the data taking mode, the nature of earlier training also evolved to include more of analysis tools, software tutorials and physics analysis. This effort epitomized as CMSDAS has proven to be a key for the new and young physicists to jump start and contribute to the physics goals of CMS by looking for new physics with the collision data. With over 400 physicists trained in six CMSDAS around the globe, CMS is trying to engage the collaboration in its discovery potential and maximize physics output. As a bigger goal, CMS is striving to nurture and increase engagement of the myriad talents, in the development of physics, service, upgrade, education of those new to CMS and the career development of younger members. An extension of the concept to the dedicated software and hardware schools is also planned, keeping in mind the ensuing upgrade phase.

    In 2011, the CMS collaboration introduced Data Scouting as a way to produce physics results with events that cannot be stored on disk, due to resource limits in the data acquisition and offline infrastructure. The viability of this technique was demonstrated in 2012, when 18 fb$^{-1}$ of collision data at $\\sqrt{s}$ = 8 TeV were collected. The technique is now a standard ingredient of CMS and ATLAS data-taking strategy. In this talk, we present the status of data scouting in CMS and the improvements introduced in 2015 and 2016, which promoted data scouting to a full-fledged, flexible discovery tool for the LHC Run II.

    During the first LHC run, CMS stored about one hundred petabytes of data. Storage accounting and monitoring help to meet the challenges of storage management, such as efficient space utilization, fair share between users and groups and resource planning. We present a newly developed CMS space monitoring system based on the storage metadata dumps produced at the sites. The information extracted from the storage dumps is aggregated and uploaded to a central database. A web based data service is provided to retrieve the information for a given time interval and a range of sites, so it can be further aggregated and presented in the desired format. The system has been designed based on the analysis of CMS monitoring requirements and experiences of the other LHC experiments. In this paper, we demonstrate how the existing software components of the CMS data placement system, PhEDEx, have been re-used, dramatically reducing the development effort.

    CMS faces real challenges with upgrade of the CMS detector through 2020 and beyond. One of the challenges, from the software point of view, is managing upgrade simulations with the same software release as the 2013 scenario. We present the CMS geometry description software model, its integration with the CMS event setup and core software. The CMS geometry configuration and selection is implemented in Python. The tools collect the Python configuration fragments into a script used in CMS workflow. This flexible and automated geometry configuration allows choosing either transient or persistent version of the same scenario and specific version of the same scenario. We describe how the geometries are integrated and validated, and how we define and handle different geometry scenarios in simulation and reconstruction. We discuss how to transparently manage multiple incompatible geometries in the same software release. Several examples are shown based on current implementation assuring consistent choice of scenario conditions. The consequences and implications for multiple/different code algorithms are discussed.

It is a rare disease complex and very few cases have been reported in dental literature. This condition is inherited as an autosomal recessive trait with variable expression. The present case report describes EVC in a 7-year-old girl, with all the tetrad of cardinal features. We found a rare dental aberration in form; appearance of single conical roots in primary molars. The management of children with EVC is multidisciplinary, with consideration for the high incidence of cardiac defects in these patients.

    Full Text Available Ellis-van Creveld (EVC syndrome is a rare autosomal recessive congenital disorder characterized by chondrodysplasia and polydactyly, ectodermal dysplasia and congenital defects of the heart. We present here a case of a 16-year-old short-limbed dwarf with skeletal deformities and bilateral postaxial polydactyly, dysplastic nails and teeth, also having left-sided facial hemiatrophy. The diagnosis of EVC syndrome was made on the basis of clinical and radiological features. To the best of our knowledge, this is the first report of EVC syndrome with facial hemiatrophy in the medical literature from India.

    On 13 September, physicists from around the world joined John Ellis in a colloquium to celebrate his 65th birthday. In our last issue, we talked to John about the Higgs, the lack of the Higgs and extra dimensions. In this second part of the interview, John speaks about the colloquium and the wide range of topics it covered, all inspired by his career.   John Ellis in his office (July 2011). How did your birthday colloquium come about? When physicists here at CERN reach a “certain age” – or reach a transition point in their careers – it is traditional to hold some kind of colloquium. I had previously resisted pressure to hold one of these events. But this year, my official duties for the Organization have come to an end.  While it is unlikely you will see any difference in my working habits, it was a milestone that proved too important to not give into requests for an event. Rather than a very long sequence of people talking about what they d...

  2. CMS Fast Simulation

    Rahmat, Rahmat

    2012-01-01

    A framework for Fast Simulation of particle interactions in the CMS detector has been developed and implemented in the overall simulation, reconstruction and analysis framework of CMS. It produces data samples in the same format as the one used by the Geant4-based (henceforth Full) Simulation and Reconstruction chain; the output of the Fast Simulation of CMS can therefore be used in the analysis in the same way as other ones. The Fast Simulation has been used already for several physics analyses in CMS, in particular those requiring a generation of many samples to scan an extended parameter space of the physics model (e.g. SUSY). Other use cases dealt with by the Fast Simulation of CMS are those involving the generation of large cross-section backgrounds, and samples of manageable size can only be produced by events skimming based on the final reconstructed objects, or those for which in general a large computation time is foreseen. An important issue, related with the high luminosity achieved by the LHC acce...

    The CMS experiment expects to manage several Pbytes of data each year during the LHC programme, distributing them over many computing sites around the world and enabling data access at those centers for analysis. CMS has identified the distributed sites as the primary location for physics analysis to support a wide community with thousands potential users. This represents an unprecedented experimental challenge in terms of the scale of distributed computing resources and number of user. An overview of the computing architecture, the software tools and the distributed infrastructure is reported. Summaries of the experience in establishing efficient and scalable operations to get prepared for CMS distributed analysis are presented, followed by the user experience in their current analysis activities.

    The Compact Muon Solenoid (CMS) is one of the general-purpose detectors to be provided for the LHC project at CERN. The design field of the CMS superconducting magnet is 4 T, the magnetic length is 12.5 m and the free bore is 6 m. The magnetic field is achieved by means of a four-layer superconducting solenoid. The stored magnetic energy is 2.7 GJ at nominal current of 20 kA (at 4.5 K operating temperature). The coil is wound from a high purity aluminum- stabilized Rutherford type conductor. Unlike other existing Al- stabilized thin solenoids, the structural integrity of the CMS coil is ensured both by the Al-alloy reinforcement welded to the conductor and an external support cylinder. The flat NbTi cable is embedded in high purity aluminum by a continuous co-extrusion process. (7 refs).

    During normal data taking CMS expects to support potentially as many as 2000 analysis users. Since the beginning of 2008 there have been more than 800 individuals who submitted a remote analysis job to the CMS computing infrastructure. The bulk of these users will be supported at the over 40 CMS Tier-2 centres. Supporting a globally distributed community of users on a globally distributed set of computing clusters is a task that requires reconsidering the normal methods of user support for Analysis Operations. In 2008 CMS formed an Analysis Support Task Force in preparation for large-scale physics analysis activities. The charge of the task force was to evaluate the available support tools, the user support techniques, and the direct feedback of users with the goal of improving the success rate and user experience when utilizing the distributed computing environment. The task force determined the tools needed to assess and reduce the number of non-zero exit code applications submitted through the grid interfaces and worked with the CMS experiment dashboard developers to obtain the necessary information to quickly and proactively identify issues with user jobs and data sets hosted at various sites. Results of the analysis group surveys were compiled. Reference platforms for testing and debugging problems were established in various geographic regions. The task force also assessed the resources needed to make the transition to a permanent Analysis Operations task. In this presentation the results of the task force will be discussed as well as the CMS Analysis Operations plans for the start of data taking.

    Full Text Available Chondroectodermal dysplasia is a rare mesenchymal - ectodermal dysplasia first described in 1940 by Richard W.B. Ellis and Simon van Creveld now known as Ellis van Creveld syndrome. It is also known as Mesvectodermal dysplasia. Majority of cases were characteristically seen in one particular inbred population from the Amish community of Lancaster County, Pennsylvania, U.S.A. The syndrome manifests with several skeletal anomalies, oral mucosal and dental anomalies, congenital cardiac defects and nail dysplasia. Ellis van Creveld syndrome may be differentiated from other chondrodystrophies like achondroplasia, chondroplasia punctata, asphyxiating thorasic dystrophy and Morquio′s syndrome. The presence of oral mucosal and dental alterations like notching of the lower alveolar process, fusion of the upper lip with gingival mucosal margin, occasional presence of neonatal teeth, oligodontia and conical shape of anterior teeth will confirm the diagnosis of Ellis van Creveld syndrome and hence its importance to dentists.

  3. Higgs searches with CMS

    CERN. Geneva

    2011-01-01

    The excellent performances of the LHC in the 2011 run are setting the grounds for the final chase of the Higgs boson. The CMS experiment is recording high quality data that are being thoroughly scrutinized. Several decay channels are investigated to probe the entire possible Higgs mass spectrum, from 110 to 600 GeV/c^2. The study of the first 1.5/fb of collected data places already tight limits and excludes large fractions of the Higgs mass range, leaving however still open the search in the theoretically favored low mass region. In this seminar we will report on the diverse CMS analyses that yield to such results describing the experimental challenges that each had to meet.

More than 25 fb^-1 of proton-proton collisions at sqrt(s)=13 TeV have been delivered to both ATLAS and CMS experiments during 2016. This enormous dataset can be used to test the Standard Model in a complete new regime with tremendous precision and it has the potential to unveil new physics or set strong bounds on it. In this talk some of the most recent results made public by the CMS Collaboration will be presented. The focus will mainly be on searches for physics beyond the Standard Model, with particular emphasis on searches for dark matter candidates.

    Rahmat, Rahmat

    2012-01-01

    The experiments at the Large Hadron Collider will have to deal with unprecedented radiation levels. The design of the CMS forward calorimetry detector (HF) is now finalized. The present design of CMS calls for the HF calorimeter to be based on quartz fiber technology. It consists of two modules, located symmetrically at about 11 meters from either side of interaction point. They cover the pseudorapidity range 3-5. The length along the beam is 1.65m or 10 nuclear interaction lenghts. Each calorimeter consists of a large steel block that serves as the absorber. Embedded quartz fibers in the steel absorber run parallel to the beam and constitute the active component of the detector. In order to optimize energy resolution for E and ET flows and forward jets, the calorimeter is effectively segmented longitudinally by using two different fiber lengths. The present status will be discussed.

    To explore perception of spokespersons' performance and characteristics in response to the 2003 severe acute respiratory syndrome (SARS) outbreak. This study was conducted from March to July, 2005, using semi-structured in-depth interviews to collect data. All interviews were audio-recorded and transcribed verbatim. A qualitative content analysis was employed to analyze the transcribed data. Interviewees included media reporters, media supervisors, health and medical institution executives or spokespersons, and social observers. Altogether, 35 interviewees were recruited for in-depth interviews, and the duration of the interview ranged from 1 hour to 2 hours. Results revealed that the most important characteristics of health/medical institutions spokespersons are professional competence and good interaction with the media. In contrast, the most important behaviors they should avoid are concealing the truth and misreporting the truth. Three major flaws of spokespersons' performance were identified: they included poor understanding of media needs and landscape; blaming the media to cover up a mistake they made in an announcement; and lack of sufficient participation in decision-making or of authorization from the head of organization. Spokespersons of health and medical institutions play an important role in media relations during the crisis of a newly emerging infectious disease. Copyright © 2013. Published by Elsevier B.V.

    2012-01-01

    The CMS simulation, based on the Geant4 toolkit, has been operational within the new CMS software framework for more than four years. The description of the detector including the forward regions has been completed and detailed investigation of detector positioning and material budget has been carried out using collision data. Detailed modeling of detector noise has been performed and validated with the collision data. In view of the high luminosity runs of the Large Hadron Collider, simulation of pile-up events has become a key issue. Challenges have raised from the point of view of providing a realistic luminosity profile and modeling of out-of-time pileup events, as well as computing issues regarding memory footprint and IO access. These will be especially severe in the simulation of collision events for the LHC upgrades; a new pileup simulation architecture has been introduced to cope with these issues. The CMS detector has observed anomalous energy deposit in the calorimeters and there has been a sub...

    When two protons collide, the simplest thing that can happen is that they emerge with no loss of energy but with a slight change of direction. This is an example of "elastic scattering”. Sometimes they lose some energy instead, a process called central diffraction, one of the diffractive phenomena that the Totem experiment observes in order to study gluon-gluon interactions.   This year, Totem and CMS signed a Memorandum of Understanding for a common upgrade of the forward region (210-220 m from the interaction point) to perform diffractive physics studies on a common ground. “Totem and CMS will coordinate the use of their detectors to measure the total mass created in the collision with unprecedented accuracy,” explains Nicola Turini, Totem Deputy Spokesperson. In the next run, for the first time, data analysis will be performed in collaboration with CMS and using some common tools. Totem will, however, run alone for special runs dedicated to the measu...

    The CMS collaboration honoured 10 of its top suppliers in the seventh annual awards ceremony The representatives of the firms that recieved the CMS Gold and Crystal Awards stand with their awards after the ceremony. The seventh annual CMS Awards ceremony was held on Monday 13 March to recognize the industries that have made substantial contributions to the construction of the collaboration's detector. Nine international firms received Gold Awards, and General Tecnica of Italy received the prestigious Crystal Award. Representatives from the companies attended the ceremony during the plenary session of CMS week. 'The role of CERN, its machines and experiments, beyond particle physics is to push the development of equipment technologies related to high-energy physics,'said CMS Awards Coordinator Domenico Campi. 'All of these industries must go beyond the technologies that are currently available.' Without the involvement of good companies over the years, the construction of the CMS detector wouldn't be possible...

    2003-01-01

    The CMS detector is mainly designed to investigate hard events. Only few Level-1 Trigger conditions are suitable to select soft B-meson decays. The B-physics potential of CMS depends strongly on a selection strategy at High-Level Trigger. The selection algorithms for some benchmark B-decay channels that allow CMS to perform competitive B-physics program are presented.

    Ellis-van Creveld (EvC) syndrome is a congenital malformation syndrome with marked growth retardation. In this study, specific growth charts for EvC patients were derived to allow better follow-up of growth and earlier detection of growth patterns unusual for EvC. With the use of 235 observations of 101 EvC patients (49 males, 52 females), growth charts for males and females from 0 to 20 years of age were derived. Longitudinal and cross-sectional data were collected from an earlier review of growth data in EvC, a database of EvC patients, and from recent literature. To model the growth charts, the GAMLSS package for the R statistical program was used. Height of EvC patients was compared to healthy children using Dutch growth charts. Data are presented both on a scale for age and on a scale for the square root of age. Compared to healthy Dutch children, mean height standard deviation score values for male and female EvC patients were -3.1 and -3.0, respectively. The present growth charts should be useful in the follow-up of EvC patients. Most importantly, early detection of growth hormone deficiency, known to occur in EvC, will be facilitated.

    Ellis-van Creveld syndrome (EVC syndrome, MIM 225500) or chondroectodermal dysplasia is a rare, autosomal recessive disorder. This syndrome is characterized by a tetrad of chondrodystrophy, post axial polydactyly, and hidrotic ectodermal dysplasia, mostly involving teeth and nails and a high frequency of congenital cardiac anomalies, most frequently a common atrium. The genetic basis of this disorder has been identified as mutations in the Evc and Evc2 genes. We present a report of two affected siblings with features consistent with those of the syndrome. A 2-month-old child with features of lower respiratory tract infection was admitted to the pediatric emergency department. Detailed examination revealed skeletal anomalies such as limb shortening and polydactyly in both hands. On cardiac evaluation, ventricular septal defect was found. There were no neonatal teeth. A diagnosis of EVC syndrome was made based on the findings. Screening of family members revealed that the elder sibling had features consistent with those of EVC syndrome. He was 4 years old, yet undiagnosed with short bones, polydactyly, partial anodontia and ventricular septal defect. The third child and the parents were unaffected. The treatment of this disorder is primarily supportive particularly for associated cardio-respiratory problems. The parents were extensively counseled for regular follow-up. The diagnosis of this syndrome is based on clinical grounds supported by radiological evaluation. Prenatal diagnosis is possible by ultrasonography and genetic testing. Genetic counseling is required to make the parents aware of the risk of recurrences.

    Full Text Available The accumulation of 19 fb−1 of data at 8 TeV has been a unique window for Supersymmetry searches at the LHC, allowing the CMS collaboration to search for specific supersymmetric particles. This article covers the search for supersymmetric particles in a variety of production-and decay-modes as well as channels. It focuses on the search for the lightest scalar top (stop in the single lepton channel, stop which might be the only observable in the case where Supersymmetry is realized in nature, and which can play a unique role in “naturalness”

    There are many types of gas detectors which are used in CERN in LHC project, There is a main parts for the gas detectors which must be in all gas detectors types like Multiwire proportional chambers, such as the micromesh gaseous structure chamber (the MicroMegas), Gas-electron multiplier (GEM) detector, Resistive Plate Champers... Compact Muon Solenoid (CMS) experiment detecting muons which are powerful tool for recognizing signatures of interesting physics processes. The CMS detector uses: drift tube (DT), cathode strip chamber (CSC) and resistive plate chamber (RPC). Building RPC’s was my project in summer student program (hardware). RPC’s have advantages which are triggering detector and Excellent time resolution which reinforce the measurement of the correct beam crossing time. RPC’s Organized in stations :  RPC barrel (RB) there are 4 stations, namely RB1, RB2, RB3, and RB4  While in the RPC endcap (RE) the 3 stations are RE1, RE2, and RE3. In the endcaps a new starion will be added and this...

  19. CMS Tracker Model

    CERN Multimedia

    Model of the tracking detector for the CMS experiment at the LHC. This object is a mock-up of an early design of the CMS Tracker mechanics. It is a segment of a “Wheel” to support Micro-Strip Gas Chamber (MSGC) detector modules on the outer layers and silicon-strip detector modules in the innermost layers. The particularity of that design is that modules are organised in spirals, along which power and optical cables and cooling pipes were planned to be routed. Some of such spirals are illustrated in the mock-up by the colors of the modules. With the detector development it became, however, evident that the silicon detectors would need to be operated in LHC experiments in cold temperatures, while the MSGC could stay in normal room-temperature. That split in two temperatures lead to separating those two detector types by a thermal barrier and therefore jeopardizing the idea of using common, vertical Wheels with services arranged along spirals.

    CMS (Compact Muon Solenoid) is a general-purpose detector designed to run in mid-2005 at the highest luminosity at the LHC at CERN. Its distinctive features include a 6 m free bore diameter, 12.5 m long, 4 T superconducting solenoid enclosed inside a 10,000 tonne return yoke. The magnet will be assembled and tested on the surface by the end of 2003 before being transferred by heavy lifting means to a 90 m deep underground experimental area. The design and construction of the magnet is a `common project' of the CMS Collaboration. It is organized by a CERN based group with strong technical and contractual participation by CEA Saclay, ETH Zurich, Fermilab Batavia IL, INFN Geneva, ITEP Moscow, University of Wisconsin and CERN. The return yoke, 21 m long and 14 m in diameter, is equivalent to 1.5 m of saturated iron interleaved with four muon stations. The yoke and the vacuum tank are being manufactured. The indirectly-cooled, pure- aluminium-stabilized coil is made up from five modules internally wound with four ...

    This paper describes the CMS trigger system and its performance during Run 1 of the LHC. The trigger system consists of two levels designed to select events of potential physics interest from a GHz (MHz) interaction rate of proton-proton (heavy ion) collisions. The first level of the trigger is implemented in hardware, and selects events containing detector signals consistent with an electron, photon, muon, $\\tau$ lepton, jet, or missing transverse energy. A programmable menu of up to 128 object-based algorithms is used to select events for subsequent processing. The trigger thresholds are adjusted to the LHC instantaneous luminosity during data taking in order to restrict the output rate to 100 kHz, the upper limit imposed by the CMS readout electronics. The second level, implemented in software, further refines the purity of the output stream, selecting an average rate of 400 Hz for offline event storage.

    2006-01-01

    A computer image of a cosmic ray traversing the many layers of the TEC+ silicon sensors. The first cosmic muon tracks have been observed in one of the CMS tracker endcaps. On 14 March, a sector on one of the two large tracker endcaps underwent a cosmic muon run. Since then, thousands of tracks have been recorded. These data will be used not only to study the tracking, but also to exercise various track alignment algorithms The endcap tested, called the TEC+, is under construction at RWTH Aachen in Germany. The endcaps have a modular design, with silicon strip modules mounted onto wedge-shaped carbon fibre support plates, so-called petals. Up to 28 modules are arranged in radial rings on both sides of these plates. One eighth of an endcap is populated with 18 petals and called a sector. The next major step is a test of the first sector at CMS operating conditions, with the silicon modules at a temperature below -10°C. Afterwards, the remaining seven sectors have to be integrated. In autumn 2006, TEC+ wil...

    2016-08-01

    Domestic violence is a worldwide epidemic. This study examines the effects of narrative exemplars and a celebrity spokesperson in anti-domestic violence ads on Lebanese college students' attitudes and beliefs towards domestic violence and whether these effects are impacted by personal experience. The practical significance is derived from the high prevalence of domestic violence internationally, making it important to find ways to effectively use media to address this health-related issue that has huge consequences for the individual and society. This study adds to the theoretical understanding of narrative persuasion and media effects. Results indicated that narrative exemplars in anti-domestic violence ads promoting bystander awareness and intervention were more beneficial for people without relevant experience compared to people who know someone affected by domestic violence. Anti-domestic violence ads without narrative exemplars, but that also featured an emotional self-efficacy appeal targeting bystanders, were more effective for participants who know someone who had experienced domestic violence compared to participants without relevant experience. The presence of a celebrity spokesperson elicited more positive attitudes about the ad than a noncelebrity, but failed to directly affect relevant anti-domestic violence attitudes or beliefs. These results highlight the significance of formative audience research in health communication message design.

    CMS is using a tiered setup of dedicated computing resources provided by sites distributed over the world and organized in WLCG. These sites pledge resources to CMS and are preparing them especially for CMS to run the experiment's applications. But there are more resources available opportunistically both on the GRID and in local university and research clusters which can be used for CMS applications. We will present CMS' strategy to use opportunistic resources and prepare them dynamically to run CMS applications. CMS is able to run its applications on resources that can be reached through the GRID, through EC2 compliant cloud interfaces. Even resources that can be used through ssh login nodes can be harnessed. All of these usage modes are integrated transparently into the GlideIn WMS submission infrastructure, which is the basis of CMS' opportunistic resource usage strategy. Technologies like Parrot to mount the software distribution via CVMFS and xrootd for access to data and simulation samples via the WAN are used and will be described. We will summarize the experience with opportunistic resource usage and give an outlook for the restart of LHC data taking in 2015.

    To impart hands-on training in physics analysis, CMS experiment initiated the  concept of CMS Data Analysis School (CMSDAS). It was born three years ago at the LPC (LHC Physics Center), Fermilab and is based on earlier workshops held at the LPC and CLEO Experiment. As CMS transitioned from construction to the data taking mode, the nature of earlier training also evolved to include more of analysis tools, software tutorials and physics analysis. This effort epitomized as CMSDAS has proven to be a key for the new and young physicists to jump start and contribute to the physics goals of CMS by looking for new physics with the collision data. With over 400 physicists trained in six CMSDAS around the globe , CMS is trying to  engage the collaboration discovery potential and maximize the physics output. As a bigger goal, CMS is striving to nurture and increase engagement of the myriad talents of CMS, in the development of physics, service, upgrade, education of those new to CMS and the caree...

    2008-01-01

    The CMS (Compact Muon Solenoid) detector will observe high transverse momentum jets produced in the final state of proton-proton collisions at the center of mass energy of 14 TeV. These data will allow us to measure jet shapes, defined as the fractional transverse momentum distribution as a function of the distance from the jet axis. Since jet shapes are sensitive to parton showering processes they provide a good test of Monte Carlo event simulation programs. In this note we present a study of jet shapes reconstructed using calorimeter energies. We compare the predictions of the Monte Carlo generators PYTHIA and HERWIG++. Presented results are expected for $pp$ collisions at 14 TeV assuming an integrated luminosity of 10 pb$^{-1}$.

    The CMS Computing Model was developed and documented in 2004. Since then the model has evolved to be more flexible and to take advantage of new techniques, but many of the original concepts remain and are in active use. In this presentation we will discuss the changes planned for the restart of the LHC program in 2015. We will discuss the changes planning in the use and definition of the computing tiers that were defined with the MONARC project. We will present how we intend to use new services and infrastructure to provide more efficient and transparent access to the data. We will discuss the computing plans to make better use of the computing capacity by scheduling more of the processor nodes, making better use of the disk storage, and more intelligent use of the networking.

    2004-01-01

    To provide improvements in the performance of existing tracker data visualization tools in IGUANA, a 2D visualisation software has been developed, using the object oriented paradigm and software engineering techniques. We have designed 2D graphics objects and some of them have been implemented. The access to the new objects is made in ORCA plugin of IGUANA CMS. A new tracker object oriented model has been designed for developing these 2D graphics objects. The model consists of new classes which represent all its components (layers, modules, rings, petals, rods).The new classes are described here. The last part of this document contains a user manual of the software and will be updated with new releases.

    2006-01-01

    The reconstruction of the energy and momentum of isolated electrons in CMS combining tracking and electromagnetic calorimetry information is described. The emphasis is put on primary electrons with transverse momentum below 50 GeV/c. The energy deposited in the electromagnetic calorimeter is measured in superclusters which collect bremsstrahlung photons emitted along the electron trajectory in the tracker volume. The electron tracks are built from seeds in the pixel detector found via a cluster-driven pixel hit matching algorithm, followed by a reconstruction of trajectories in the silicon strip tracker with a Gaussian Sum Filter. Electrons are classified using observables sensitive to the pattern of bremsstrahlung emission and electromagnetic showering in the tracker material. Energy scale corrections depending on the electron class are applied to the supercluster and estimates of associated errors are obtained. The electron energy is deduced from a weighted combination of the corrected supercluster energy a...

    The LHC machine at CERN finished its first year of pp collisions at a center of mass energy of 7~TeV. While the commissioning to exploit its full potential is still ongoing, there are plans to upgrade its components to reach instantaneous luminosities beyond the initial design value after 2016. A corresponding upgrade of the innermost part of the CMS detector, the pixel detector, is needed. A full replacement of the pixel detector is planned in 2016. It will not only address limitations of the present system at higher data rates, but will aggressively lower the amount of material inside the fiducial tracking volume which will lead to better tracking and b-tagging performance. This article gives an overview of the project and illuminates the motivations and expected improvements in the detector performance.

    2008-01-01

    The CMS experiment is getting ready to take data at the LHC accelerator at CERN. Due to late delivery of the experimental caverns the detector had to be pre-assembled on the surface and lowered in large segments. This has constrained the commissioning strategy of the experiment. Global commissioning has started in Spring of 2007 and has progressed in parallel with the construction and assembly of detector and services underground. This paper describes the strategy adopted in order to commission components of the system in incremental steps in order to be ready to accept collisions from LHC with a well debugged and understood system, including the detector, acquisition system, trigger, software, computing and data shipping.

  15. Electroweak Results from CMS

    CERN Multimedia

    CERN. Geneva

    2016-01-01

    We present recent CMS measurements on electroweak boson production including single, double, and triple boson final states. Electroweak processes span many orders of magnitude in production cross section. Measurements of high-rate processes provide stringent tests of the standard model. In addition, rare triboson proceses and final states produced through vector boson scattering are newly accessible with the large integrated luminosity provided by the LHC. If new physics lies just beyond the reach of the LHC, its effects may manifest as enhancements to the high energy kinematics in mulitboson production. We present limits on new physics signatures using an effective field theory which models these modifications as modifications of electroweak gauge couplings. Since electroweak measurements will continue to benefit from the increasing integrated luminosity provided by the LHC, the future prospects of electroweak physics are discussed.

    A new muon reconstruction algorithm is introduced at the CMS experiment. This algorithm reconstructs muons using only the central tracker and the Resistive Plate Chamber (RPC). The aim of this work is to study how a muon reconstructed only with tracker and RPC information would perform compared to the standard muon reconstruction of the CMS detector. The efficiencies to reconstruct and identify a RPC muon with a transverse momentum greater than 20 GeV/c are measured. The probabilities to misidentify hadrons as muons at low transverse momentum are also reported. These probabilities are compared to the standard muon identification used at CMS.

  20. Improving collaborative documentation in CMS

    International Nuclear Information System (INIS)

    2010-01-01

    Complete and up-to-date documentation is essential for efficient data analysis in a large and complex collaboration like CMS. Good documentation reduces the time spent in problem solving for users and software developers. The scientists in our research environment do not necessarily have the interests or skills of professional technical writers. This results in inconsistencies in the documentation. To improve the quality, we have started a multidisciplinary project involving CMS user support and expertise in technical communication from the University of Turku, Finland. In this paper, we present possible approaches to study the usability of the documentation, for instance, usability tests conducted recently for the CMS software and computing user documentation.

  1. Generalized Rainich conditions, generalized stress-energy conditions, and the Hawking-Ellis classification

    Science.gov (United States)

    Martín–Moruno, Prado; Visser, Matt

    2017-11-01

    The (generalized) Rainich conditions are algebraic conditions which are polynomial in the (mixed-component) stress-energy tensor. As such they are logically distinct from the usual classical energy conditions (NEC, WEC, SEC, DEC), and logically distinct from the usual Hawking-Ellis (Segré-Plebański) classification of stress-energy tensors (type I, type II, type III, type IV). There will of course be significant inter-connections between these classification schemes, which we explore in the current article. Overall, we shall argue that it is best to view the (generalized) Rainich conditions as a refinement of the classical energy conditions and the usual Hawking-Ellis classification.

    The measurement of the energy of electrons and photons with very high accuracy is of primary importance far the study of many physics processes at the Large Hadron Collider (LHC), in particular for the search of the Higgs Boson. The CMS experiment will use a crystal calorimeter with pointing geometry, almost covering 4p, as it offers a very good energy resolution. It is divided into a barrel composed of 61200 lead tungstate crystals, two end-caps with 14648 crystals and a pre-shower detector in front of the end-cap. The challenges of the calorimeter design arise from the high radiation environment, the 4 Tesla magnetic eld, the high bunch crossing rate of 40 MHz and the large dynamic range, requiring the development of fast, radiation hard crystals, photo-detectors and readout electronics. An overview of the construction and design of the calorimeter will be presented, with emphasis on some of the details required to meet the demanding performance goals. 19 Refs.

    2017-01-01

    During its second run of operation (Run 2) which started in 2015, the LHC will deliver a peak instantaneous luminosity that may reach $2 \\cdot 10^{34}$ cm$^{-2}$s$^{-1}$ with an average pile-up of about 55, far larger than the design value. Under these conditions, the online event selection is a very challenging task. In CMS, it is realized by a two-level trigger system the Level-1 (L1) Trigger, implemented in custom-designed electronics, and the High Level Trigger (HLT), a streamlined version of the offline reconstruction software running on a computer farm. In order to face this challenge, the L1 trigger has been through a major upgrade compared to Run 1, whereby all electronic boards of the system have been replaced, allowing more sophisticated algorithms to be run online. Its last stage, the global trigger, is now able to perform complex selections and to compute high-level quantities, like invariant masses. Likewise, the algorithms that run in the HLT go through big improvements; in particular, new appr...

  8. CMS Multicore Scheduling Strategy

    Perez-Calero Yzquierdo, Antonio

    2014-01-01

    In the next years, processor architectures based on much larger numbers of cores will be most likely the model to continue Moores Law style throughput gains. This not only results in many more jobs in parallel running the LHC Run 1 era monolithic applications. Also the memory requirements of these processes push the workernode architectures to the limit. One solution is parallelizing the application itself, through forking and memory sharing or through threaded frameworks. CMS is following all of these approaches and has a comprehensive strategy to schedule multi-core jobs on the GRID based on the glideIn WMS submission infrastructure. We will present the individual components of the strategy, from special site specific queues used during provisioning of resources and implications to scheduling; to dynamic partitioning within a single pilot to allow to transition to multi-core or whole-node scheduling on site level without disallowing single-core jobs. In this presentation, we will present the experiences mad...

    In the next years, processor architectures based on much larger numbers of cores will be most likely the model to continue 'Moore's Law' style throughput gains. This not only results in many more jobs in parallel running the LHC Run 1 era monolithic applications, but also the memory requirements of these processes push the workernode architectures to the limit. One solution is parallelizing the application itself, through forking and memory sharing or through threaded frameworks. CMS is following all of these approaches and has a comprehensive strategy to schedule multicore jobs on the GRID based on the glideinWMS submission infrastructure. The main component of the scheduling strategy, a pilot-based model with dynamic partitioning of resources that allows the transition to multicore or whole-node scheduling without disallowing the use of single-core jobs, is described. This contribution also presents the experiences made with the proposed multicore scheduling schema and gives an outlook of further developments working towards the restart of the LHC in 2015.

    This study examined the joint influence of spokesperson type in obesity public service announcements (PSAs) and viewer weight on diet intention, exercise intention, information seeking, and electronic word-of-mouth (eWoM) intention. Results of a 2 (spokesperson type: real person vs. actor) × 2 (viewer weight: overweight vs. non-overweight) between-subjects experiment indicated that overweight viewers who saw the PSA featuring the real person had the highest diet intention, exercise intention, information seeking, and eWoM intention. Parasocial interaction was also found to mediate the relationships between spokesperson type/viewer weight and two of the dependent variables: diet intention and exercise intention. In addition, viewers who saw the PSA featuring the real person rated the spokesperson as significantly higher on source credibility (trustworthiness, competence, and goodwill) than those who saw the PSA featuring the actor.

    2007-01-01

    Supported by a gigantic crane and a factory-size room full of enthusiasm, the central barrel of CMS made its final journey underground on 28 February. The central section of the CMS detector starts its dramatic 10-hour descent underground.Several hours (and 100 metres) later, the massive barrel rests on the cavern floor. CMS scientists, journalists, photographers and members of the transport crew basked in the final rays of the 'solenoid-set' on 28 February as the central barrel of the CMS detector sinks below the horizon and began its ten-hour descent into the cavern 100 metres below. Thirteen metres long and weighing as much as five jumbo jets (1920 tonnes), the barrel is the largest of the 15 chunks of CMS detector that are being lowered one by one into the cavern. 'This is a challenging feat of engineering, as there are just 20 cm of leeway between the detector and the walls of the shaft,' said Austin Ball, Technical Coordinator of CMS.

  13. The CMS Detector Power System

    CERN Document Server

    Lusin, S

    2008-01-01

    The power system for the on-detector electronics of the CMS Experiment comprises approximately 12000 low voltage channels, with a total power requirement of 1.1 MVA. The radiation environment inside the CMS experimental cavern combined with an ambient magnetic field (reaching up to 1.3 kGauss at the detector periphery) severely limit the available choices of low voltage supplies, effectively ruling out the use of commercial off-the-shelf DC power supplies. Typical current requirements at the CMS detector front end range from 1A-30A per channel at voltages ranging between 1.25V and 8V. This requires in turn that the final stage of the low voltage power supply be located on the detector periphery. Power to the CMS front-end electronics is stabilized by a 2 MVA uninterruptible power supply (UPS) located in a CMS surface building. This UPS isolates the CMS detector from disturbances on the local power grid and provides for 2 minutes of autonomy following a power failure, allowing for an orderly shutdown of detect...

    The CMS Dataset Bookkeeping Service (DBS) has been developed to catalog all CMS event data from Monte Carlo and Detector sources. It provides the ability to identify MC or trigger source, track data provenance, construct datasets for analysis, and discover interesting data. CMS requires processing and analysis activities at various service levels and the DBS system provides support for localized processing or private analysis, as well as global access for CMS users at large. Catalog entries can be moved among the various service levels with a simple set of migration tools, thus forming a loose federation of databases. DBS is available to CMS users via a Python API, Command Line, and a Discovery web page interfaces. The system is built as a multi-tier web application with Java servlets running under Tomcat, with connections via JDBC to Oracle or MySQL database backends. Clients connect to the service through HTTP or HTTPS with authentication provided by GRID certificates and authorization through VOMS.

Catalog entries can be moved among the various service levels with a simple set of migration tools, thus forming a loose federation of databases. DBS is available to CMS users via a Python API, Command Line, and a Discovery web page interfaces. The system is built as a multi-tier web application with Java servlets running under Tomcat, with connections via JDBC to Oracle or MySQL database backends. Clients connect to the service through HTTP or HTTPS with authentication provided by GRID certificates and authorization through VOMS. DBS is an integral part of the overall CMS Data Management and Workflow Management systems

    Full Text Available Background: Control of angry in effective manner is very important. In present study we compared the effect of reinforcement behavioral therapy and Ellis cognitive therapy on decreasing of aggression in derelict children aged 10 to 18 years old at hostelry care center of Welfare Organization of Kermanshah. Methods: Fifty-seven out of 89 children (31 male, 26 female was diagnosed as aggressive according to the AGQ results from six hostelry care center of welfare organization of Kermanshah, were selected and participated in the study. Participants allocated in to reinforcement behavioral therapy, Ellis cognitive therapy or control group randomly. Each groups received two hours therapeutic teaching for 10 sessions during 10 weeks. The control group had not been received any intervention. After 10 weeks, the posttest AGQ was performed on participant. The results of pretest and posttest were compared using T-test and ANOVA.Results: The posttest aggression score in reinforcement behavioral therapy group was decreased significantly after intervention (P=0.011. We didn’t find significant differences between pre and post tests aggression score in Ellis cognitive therapy (P=0.258. Result of ANOVA show that there was no significant difference between three group after intervention (P=0.691Conclusion: Reinforcement behavioral therapy and Ellis cognitive therapy did not change the aggression score in derelict children. This may relate to specific hard and stressful life of these children due to ineffectiveness of these short-term methods.

    The CMS hadron calorimeter is a sampling calorimeter with brass absorber and plastic scintillator tiles with wavelength shifting fibres for carrying the light to the readout device. The barrel hadron calorimeter is complemented with a outer calorimeter to ensure high energy shower containment in CMS and thus working as a tail catcher. Fabrication, testing and calibrations of the outer hadron calorimeter are carried out keeping in mind its importance in the energy measurement of jets in view of linearity and resolution. It will provide a net improvement in missing $\\et$ measurements at LHC energies. The outer hadron calorimeter has a very good signal to background ratio even for a minimum ionising particle and can hence be used in coincidence with the Resistive Plate Chambers of the CMS detector for the muon trigger.

    The vast majority of the CMS Computing capacity, which is organized in a tiered hierarchy, is located away from CERN. The 7 Tier-1 sites archive the LHC proton-proton collision data that is initially processed at CERN. These sites provide access to all recorded and simulated data for the Tier-2 sites, via wide-area network (WAN) transfers. All central data processing workflows are executed at the Tier-1 level, which contain re-reconstruction and skimming workflows of collision data as well as reprocessing of simulated data to adapt to changing detector conditions. This paper describes the operation of the CMS processing infrastructure at the Tier-1 level. The Tier-1 workflows are described in detail. The operational optimization of resource usage is described. In particular, the variation of different workflows during the data taking period of 2010, their efficiencies and latencies as well as their impact on the delivery of physics results is discussed and lessons are drawn from this experience. The simulation of proton-proton collisions for the CMS experiment is primarily carried out at the second tier of the CMS computing infrastructure. Half of the Tier-2 sites of CMS are reserved for central Monte Carlo (MC) production while the other half is available for user analysis. This paper summarizes the large throughput of the MC production operation during the data taking period of 2010 and discusses the latencies and efficiencies of the various types of MC production workflows. We present the operational procedures to optimize the usage of available resources and we the operational model of CMS for including opportunistic resources, such as the larger Tier-3 sites, into the central production operation.

    Full Text Available CMS plans for operation at the LHC phase-II unprecedented in terms of luminosity thus resulting in serious consequences for detector performance. To achieve the goal to maintain the present excellent performance of the CMS detector, several upgrades are necessary. To handle the high phase-II data rates, the readout and trigger systems are redesigned using recent technology developments. The high particle rates will accelerate detector aging and require replacement of the tracker and forward calorimeters. In addition, the muon system will be extended.

    CMS has searched for supersymmetry using the full dataset recorded until the end of 2012, at a center-of-mass energy of 8 TeV corresponding to an integrated luminosity of 20 fb-1. The observations are consistent with the expectations from the standard model. CMS maintains a broad spectrum of search strategies that target a wide range of supersymmetric scenarios. A selection of results from very inclusive and almost model-independent searches to very specific and specialized analyses will be discussed in this article.

    The CMS experiment has implemented a flexible and powerful system enabling users to find data within the CMS physics data catalog. The Dataset Bookkeeping Service (DBS) comprises a database and the services used to store and access metadata related to CMS physics data. To this, we have added a generalized query system in addition to the existing web and programmatic interfaces to the DBS. This query system is based on a query language that hides the complexity of the underlying database structure by discovering the join conditions between database tables. This provides a way of querying the system that is simple and straightforward for CMS data managers and physicists to use without requiring knowledge of the database tables or keys. The DBS Query Language uses the ANTLR tool to build the input query parser and tokenizer, followed by a query builder that uses a graph representation of the DBS schema to construct the SQL query sent to underlying database. We will describe the design of the query system, provid...

  17. Status of the CMS Detector

    Science.gov (United States)

    Focardi, Ettore

    The Compact Muon Solenoid (CMS) detector is one of the two largest and most powerful particle physics detectors ever built. CMS is installed in P5 at CERN's Large Hadron Collider (LHC) and as of early 2011 has completed nearly a year of operation in which it recorded products of interactions produced in protonproton collisions at a center of mass energy of 7 TeV. The proton-proton run 2010 lasted 7 months and was followed by Pb-Pb ion collisions in November. During the first few months of 2011 the LHC has delivered higher luminosity. The LHC machine is performing extremely well, allowing CMS to record enough data to perform a large number of studies of the Standard Model (SM) of particle physics in this new energy domain for the first time and to search for evidence of new physics in regions of phase space that have never before been entered. The CMS detector components, the operational experience and the performance with colliding beams will be described.

    On 5 and 11 November, almost 90 pupils from the Fermi scientific high school in Livorno, Italy, took part in two Masterclass sessions organised by CMS.   CMS Masterclass participants.  The pupils took over a hall at CERN for an afternoon to test a new software tool called CIMA (CMS Instrument for Masterclass Analysis) for the first time. The software simplifies the process of recording results and reduces the number of steps required to enter data. During the exercise, each group of pupils had to analyse about a hundred events from the LHC. For each event, the budding physicists determined whether what they saw was a candidate W boson, Z boson or Higgs boson, identified the decay mode and entered key data. At the end of the analysis, they used the results to reconstruct a mass diagram. CIMA was developed by a team of scientists from the University of Aachen, Germany, the University of Notre-Dame, United States, and CERN. CMS has also added yet another educational tool to its already l...

    Ellis-van Creveld syndrome is an autosomal recessive disorder characterised by short stature with short limbs, postaxial polydactyly and congenital cardiac defects. The syndrome can be caused by mutations in the EVC gene or the EVC2 gene. The genes are located close to each other in a head-to-head configuration on chromosome 4p16. Clinical diagnosis can be confirmed by DNA analysis, which is currently offered by two laboratories in Italy.

  6. Taking prisoners: Havelock Ellis, Sigmund Freud, and the construction of homosexuality, 1897-1951.

    Science.gov (United States)

    Crozier, I D

    2000-12-01

    This paper addresses the efforts of both Havelock Ellis and Sigmund Freud to posit a theory of homosexuality, and especially considers their efforts to (re-)negotiate each other's theories. Its central premise derives from the sociology of scientific knowledge: that it is not what is written, but the way that what is written is treated by ensuing experts, that makes knowledge. In the case study used in this paper, Ellis and Freud struggle to posit what they consider to be the proper model for understanding homosexual desire. They utilize aspects of each other's word, but are careful not to appear to be following each other too closely. Such a struggle to establish different schools of thought is exemplified by the informal negotiations engaged in when a student, Joseph Wortis, made contact with both Freud and Ellis. Again following sociology of scientific knowledge precepts, these informal negotiations (contained in published and archival letters) are used to show how knowledge claims are constructed, deconstructed any reconstructed by the actors who have stakes in the outcome of what is to be regarded as knowledge in the relevant communities.

  7. The CMS Muon System Alignment

    CERN Document Server

    Martinez Ruiz-Del-Arbol, P

    2009-01-01

    The alignment of the muon system of CMS is performed using different techniques: photogrammetry measurements, optical alignment and alignment with tracks. For track-based alignment, several methods are employed, ranging from a hit and impact point (HIP) algorithm and a procedure exploiting chamber overlaps to a global fit method based on the Millepede approach. For start-up alignment as long as available integrated luminosity is still significantly limiting the size of the muon sample from collisions, cosmic muon and beam halo signatures play a very strong role. During the last commissioning runs in 2008 the first aligned geometries have been produced and validated with data. The CMS offline computing infrastructure has been used in order to perform improved reconstructions. We present the computational aspects related to the calculation of alignment constants at the CERN Analysis Facility (CAF), the production and population of databases and the validation and performance in the official reconstruction.

    Initial applications of the GriPhyN Chimera Virtual Data System have been performed within the context of CMS Production of Monte Carlo Simulated Data. The GriPhyN Chimera system consists of four primary components: 1) a Virtual Data Language, which is used to describe virtual data products, 2) a Virtual Data Catalog, which is used to store virtual data entries, 3) an Abstract Planner, which resolves all dependencies of a particular virtual data product and forms a location and existence independent plan, 4) a Concrete Planner, which maps an abstract, logical plan onto concrete, physical grid resources accounting for staging in/out files and publishing results to a replica location service. A CMS Workflow Planner, MCRunJob, is used to generate virtual data products using the Virtual Data Language. Subsequently, a prototype workflow manager, known as WorkRunner, is used to schedule the instantiation of virtual data products across a grid.

    2012-01-01

    The CMS Silicon Strip Tracker (SST), consisting of 9.6 million readout channels from 15148 modules and covering an area of 198 square meters, needs to be precisely calibrated in order to correctly reconstruct the events recorded. Calibration constants are derived from different workflows, from promptly reconstructed events with particles as well as from commissioning events gathered just before the acquisition of physics runs. The performance of the SST has been carefully studied since the beginning of data taking: the noise of the detector, data integrity, signal-over-noise ratio, hit reconstruction efficiency and resolution have been all investigated with time and for different conditions. In this paper we describe the reconstruction strategies, the calibration procedures and the detector performance results from the latest CMS operation.

    Flavour-tagging of jets is an important task in collider based high energy physics and a field where machine learning tools are applied by all major experiments. A new tagger (DeepFlavour) was developed and commissioned in CMS that is based on an advanced machine learning procedure. A deep neural network is used to do multi-classification of jets that origin from a b-quark, two b-quarks, a c-quark, two c-quarks or light colored particles (u, d, s-quark or gluon). The performance was measured in both, data and simulation. The talk will also include the measured performance of all taggers in CMS. The different taggers and results will be discussed and compared with some focus on details of the newest tagger.

  12. HGCal Simulation Analyses for CMS

    Bruno, Sarah Marie

    2015-01-01

    This summer, I approached the topic of fast-timing detection of photons from Higgs decays via simulation analyses, working under the supervision of Dr. Adolf Bornheim of the California Institute of Technology. My specific project focused on simulating the high granularity calorimeter for the Compact Muon Solenoid (CMS) experiment. CMS detects particles using calorimeters. The Electromagnetic Calorimeter (ECal) is arranged cylindrically to form a barrel section and two “endcaps.” Previously, both the barrel and endcap have employed lead tungstate crystal detectors, known as the “shashlik” design. The crystal detectors, however, rapidly degrade from exposure to radiation. This effect is most pronounced in the endcaps. To avoid the high expense of frequently replacing degraded detectors, it was recently decided to eliminate the endcap crystals in favor of an arrangement of silicon detectors known as the “High Granularity Calorimeter” (HGCal), while leaving the barrel detector technology unchanged.

    One of the first events reconstructed in the Muon Drift Tubes, the Hadron Calorimeter and elements of the Silicon Tracker (TK) at 3 Tesla. The atmosphere in the CMS control rooms was electric. Everbody was at the helm for the first full-scale testing of the experiment. This was a crunch moment for the entire collaboration. On Tuesday, 22 August the magnet attained almost its nominal power of 4 Tesla! At the same moment, in a tiny improvised control room, the physicists were keyed up to test the entire detector system for the first time. The first cosmic ray tracks appeared on their screens in the week of 15 August. The tests are set to continue for several weeks more until the first CMS components are lowered into their final positions in the cavern.

    With the growth in size and complexity of High Energy Physics experiments, and the accompanying increase in the number of collaborators spread across the globe, the importance of widely relaying timely monitoring and status information has grown. To this end, we present online Web Based Monitoring solutions from the CMS experiment at CERN. The web tools developed present data to the user from many underlying heterogeneous sources, from real time messaging system to relational databases. We provide the power to combine and correlate data in both graphical and tabular formats of interest to the experimentalist, with data such as beam conditions, luminosity, trigger rates, detector conditions and many others, allowing for flexibility on the user side. We also present some examples of how this system has been used during CMS commissioning and early beam collision running at the Large Hadron Collider.

    The CMS detector is a powerful instrument that was designed to discover physics beyond the Standard Model (SM). CMS plan to begin in 2009 by\\rediscovering" the SM. At lowest luminosity the underlying event and zero bias event will be measured. Next, jets at low Pt will be recorded and the spectra of Pt, mass, and scattering angle will be validated, both for dijets and photon + jet topologies, conrming the strong and EM sector of the SM. Since at the LHC the W cross section is 100 nb, early data on the W and Z cross section, W charge asymmetry, Z mass and width and Z decay asymmetry will serve to conrm the electroweak SM. Finally, the top cross section of 1 nb will provide a \\standard candle" for b jets, leptons and missing transverse energy (MET) all of which are crucial elements in searches beyond the SM. With this foundation, CMS will search for SUSY, extra dimensions and other signals of new Physics beyond the SM, some of which will be accessible in the data taken in 2009

    2011-01-01

    We present the results of electroweak studies performed using data collected in 2010 at a center-of-mass energy of 7 TeV by the CMS experiment at the LHC. Besides their intrinsic interest as unique samples to calibrate and understand the CMS detector response to leptons, jets and missing energy, events containing W and Z bosons appear as dominant components in many Higgs seaches and in most of the searches beyond the Standard Model, either as signal or as background. In addition, the excellent level of theoretical and experimental understanding of these processes allows electroweak tests at the LHC at an unprecendented level of precision. CMS uses a wide range of final states to measure cross sections, asymmetries, polarizations and differential distributions in general. The current integrated luminosity is already sufficient to perform not just inclusive measurements using W and Z decays into muons and electrons, but also precise studies of associated jet production and final states containing taus, as well...

    The CMS Experiment at the LHC has established a network of more than fifty inter-connected 'CMS Centres' at CERN and in institutes in the Americas, Asia, Australasia, and Europe. These facilities are used by people doing CMS detector and computing grid operations, remote shifts, data quality monitoring and analysis, as well as education and outreach. We present the computing, software, and collaborative tools and videoconferencing systems. These include permanently running 'telepresence' video links (hardware-based H.323, EVO and Vidyo), Webcasts, and generic Web tools such as CMS-TV for broadcasting live monitoring and outreach information. Being Web-based and experiment-independent, these systems could easily be extended to other organizations. We describe the experiences of using CMS Centres Worldwide in the CMS data-taking operations as well as for major media events with several hundred TV channels, radio stations, and many more press journalists simultaneously around the world.

Soon physicists around the world will participate together in analyzing CMS data in search of new physics phenomena and the Higgs Boson. However, they face a significant problem: with 5 Petabytes of data needing distribution each year, how will physicists get the data they need? How and where will they be able to analyze it? Computing resources and scientists are scattered around the world, while CMS data exists in localized chunks. The CMS computing model only allows analysis of locally stored data, “tethering” analysis to storage.

For physics improvements migration from Geant4 9.4p03 to Geant4 10.0p02 has been performed. CPU performance has been improved by introduction of the Russian roulette method inside CMS calorimeters, optimization of CMS simulation sub-libraries, and usage of statics build of the simulation executable. As a result of these efforts, CMS simulation has been speeded up by about factor two. In this work we provide description of updates for different software components of CMS simulation.

    With the increased pressure on computing brought by the higher energy and luminosity from the LHC in Run 2, CMS Computing Operations expects to require the ability to utilize “opportunistic” resources — resources not owned by, or a priori configured for CMS — to meet peak demands. In addition to our dedicated resources we look to add computing resources from non CMS grids, cloud resources, and national supercomputing centers. CMS uses the HTCondor/glideinWMS job submission infrastructure for all its batch processing, so such resources will need to be transparently integrated into its glideinWMS pool. Bosco and parrot wrappers are used to enable access and bring the CMS environment into these non CMS resources. Here we describe our strategy to supplement our native capabilities with opportunistic resources and our experience so far using them.

    CMS has started the process of rolling out a new workload management system. This system is currently used for reprocessing and Monte Carlo production with tests under way using it for user analysis. It was decided to combine, as much as possible, the production/processing, analysis and T0 codebases so as to reduce duplicated functionality and make best use of limited developer and testing resources. This system now includes central request submission and management (Request Manager), a task queue for parcelling up and distributing work (WorkQueue) and agents which process requests by interfacing with disparate batch and storage resources (WMAgent).

    LHC experiments have large amounts of software to build. CMS has studied ways to shorten project build times using parallel and distributed builds as well as improved ways to decide what to rebuild. We have experimented with making idle desktop and server machines easily available as a virtual build cluster using distcc and zeroconf. We have also tested variations of ccache and more traditional make dependency analysis. We report on our test results, with analysis of the factors that most improve or limit build performance.

    An overview of recent results on electroweak precision measurements from the CMS Collaboration is presented. Studies of the weak boson differential transverse momentum spectra, Z boson angular coefficients, forward-backward asymmetry of Drell-Yan lepton pairs and charge asymmetry of W boson production are made in comparison to the state-of-the-art Monte Carlo generators and theoretical predictions. The results show a good agreement with the Standard Model. As a proof of principle for future W mass measurements, a W-like analysis of the Z boson mass is performed.

    Ellis van Creveld syndrome and Weyers acrofacial dysostosis are allelic disorders caused by mutations in EVC or EVC2 genes. We illustrate the results of direct analysis of whole EVC and EVC2 genes' coding regions in 32 unrelated families with clinical diagnosis of Ellis van Creveld syndrome and in 2 families with Weyers acrofacial dysostosis. We identified mutations in 27/32 (84%) cases with Ellis van Creveld syndrome and 2/2 cases with Weyers acrofacial dysostosis. Of the Ellis van Creveld syndrome cases, 20/27 (74%) had a mutation in EVC and 7/27 (26%) in EVC2 genes. The two subjects with Weyers acrofacial dysostosis had a heterozygous mutation in the last exon of EVC2. In total, we detected 25 independent EVC and 11 independent EVC2 mutations. Nineteen EVC mutations (19/25, 76%) and 4 EVC2 mutations (4/11, 36%) were novel. Also one EVC2 gene mutation found in Weyers acrofacial dysostosis was novel. In 5 unrelated cases with a clinical diagnosis of Ellis van Creveld syndrome, we did not find any mutation in either EVC or EVC2 genes. Current findings expand the Ellis van Creveld syndrome and Weyers acrofacial dysostosis mutation spectra, and provide further evidence that the last exon of EVC2 gene is a hot spot for Weyers acrofacial dysostosis mutations. Accordingly, EVC2 exon 22 should be analyzed with priority by mutation screening in individuals with a suspected diagnosis of Weyers acrofacial dysostosis. Copyright © 2012 Elsevier Masson SAS.

  4. Progress on CMS detector lowering

    CERN Multimedia

    2006-01-01

    It was an amazing engineering challenge - the lowering of the first hugeendcap disc (YE+3) of the CMS detector slowly and carefully 100 metres underground. The spectacular descent took place on 30 November and was documented by a film crew from Reuters news group. The uniquely shaped slice is 16 m high, about 50 cm thick, and weighs 400 tonnes. It is one of 15 sections that make up the complete CMS detector. The solid steel structure of the disc forms part of the magnet return yoke and is equipped on both sides with muon chambers. A special gantry crane lowered the element, with just 20 cm of leeway between the edges of the detector and the walls of the shaft! On 12 December, a further section of the detector (YE+2) containing the cathode strip chamber made the 10-hour journey underground. This piece is 16 m high and weighs 880 tonnes. There are now four sections of the detector in the experimental cavern, with a further 11 to follow. The endcap disc YE+3 (seen in the foreground) begins its journey down the ...

  5. CMS Distributed Computing Workflow Experience

    Haas, Jeffrey David

    2010-01-01

    The vast majority of the CMS Computing capacity, which is organized in a tiered hierarchy, is located away from CERN. The 7 Tier-1 sites archive the LHC proton-proton collision data that is initially processed at CERN. These sites provide access to all recorded and simulated data for the Tier-2 sites, via wide-area network (WAN) transfers. All central data processing workflows are executed at the Tier-1 level, which contain re-reconstruction and skimming workflows of collision data as well as reprocessing of simulated data to adapt to changing detector conditions. This paper describes the operation of the CMS processing infrastructure at the Tier-1 level. The Tier-1 workflows are described in detail. The operational optimization of resource usage is described. In particular, the variation of different workflows during the data taking period of 2010, their efficiencies and latencies as well as their impact on the delivery of physics results is discussed and lessons are drawn from this experience.

    The studies of the production of the $X(3872)$, either prompt or from B hadron decays, and of the $J/\\psi \\phi$ mass spectrum in B hadron decays have been carried out by using $pp$ collisions at $\\sqrt{s}=7$ TeV collected with the CMS detector at the LHC. %The production of the $X(3872)$ is studied in $pp$ collisions at $\\sqrt{s} = 7$ TeV with the CMS detector at LHC, using decays to $J/\\psi\\pi^{+}\\pi^{-}$ where the $J/\\psi$ decays to two muons. The cross-section ratio of the $X(3872)$ with respect to the $\\psi(2S)$ in the $J/\\psi\\pi^{+}\\pi^{-}$ decay channel and the fraction of $X(3872)$ coming from B-hadron decays are measured as a function of transverse momentum ($p\\mathrm{_T}$), covering unprecedentedly high values of $p\\mathrm{_T}$.

    The Tracker Control System (TCS) is a distributed control software to operate about 2000 power supplies for the silicon modules of the CMS Tracker and monitor its environmental sensors. TCS must thus be able to handle about 104 power supply parameters, about 103 environmental probes from the Programmable Logic Controllers of the Tracker Safety System (TSS), about 105 parameters read via DAQ from the DCUs in all front end hybrids and from CCUs in all control groups. TCS is built on top of an industrial SCADA program (PVSS) extended with a framework developed at CERN (JCOP) and used by all LHC experiments. The logical partitioning of the detector is reflected in the hierarchical structure of the TCS, where commands move down to the individual hardware devices, while states are reported up to the root which is interfaced to the broader CMS control system. The system computes and continuously monitors the mean and maximum values of critical parameters and updates the percentage of currently operating hardware. Automatic procedures switch off selected parts of the detector using detailed granularity and avoiding widespread TSS intervention.

    We discuss the status and some recent results of the CMS experiment at the LHC. The performance of the detector is assessed using a luminosity of $\\approx 5~\\mathrm{fb}^{-1}$ recorded in the first part of the 2017 data-taking period. Run~2 physics studies use data collected at a center-of-mass energy of $\\sqrt{s}=13~\\mathrm{TeV}$, corresponding to an integrated luminosity of $36~\\mathrm{fb}^{-1}$. Highlights from studies in the Higgs sector are the first observation of its decay into tau leptons by a single experiment, the most precise measurement of its mass, $\\mathrm{m_H} = 125.26 \\pm 0.21~\\mathrm{GeV}$ and a first search for the $\\mathrm{H}\\to\\mathrm{b\\overline{b}}$ decay in a phase space region that is sensitive to the gluon-fusion production mechanism. In the electroweak sector, CMS provides the currently most precise measurement of the effective weak mixing angle at the LHC: $\\sin\\theta^{\\rm lept}_{\\rm eff} = 0.23101\\pm 0.00052$, using an integrated luminosity of $\\approx 20~\\mathrm{fb}^{-1}$ at $\\sqr...

    Ellis-van Creveld (EvC) syndrome is an autosomal recessive chondrodysplasia characterized by short limbs, postaxial polydactyly, natal teeth, and dysplastic nails. The Ellis-van Creveld (EVC) gene, which is mutated in patients with EvC syndrome, has been identified by positional cloning. However, the physiological roles of the EVC gene have not been elucidated. Histopathological analyses of EvC syndrome have shown disturbed chondrocytic phenotypes during cartilage development. We therefore postulated that the EVC gene is a critical factor for chondrocytes during endochondral ossification. The present study focuses on the relationship between the Evc gene and chondrocytes, and examines Evc gene expression in the rat tibial growth plate at the mRNA and protein levels. Evc mRNA in tibial epiphyseal cartilage was expressed at postnatal day (P) 1, P28, and P56 by RT-PCR. Immunohistochemical analyses localized the Evc protein mainly in prehypertrophic and hypertrophic chondrocytes of the epiphyseal growth plate in the tibia during the embryonic and postnatal periods. Evc mRNA was also detected in prehypertrophic and hypertrophic chondrocytes by in situ hybridization. These results indicate that the Evc gene functions mainly in the prehypertrophic and hypertrophic chondrocytes of the epiphyseal growth plate. The data presented here are important for future studies of the underlying mechanism of chondrodysplasia in EvC syndrome.

So, let’s start from the Higgs boson: does it exist and where is it? The million-dollar question… Sometime in the next few months, I think we will finally get clarity on the Higgs boson. While it has been with us as a hypothesis since 1964, I think we are finally closing in on it now. However, in every possible discovery scenario, clarity on the Higgs will lead to new physics. Let me explain... Experiments have left only three possible mass ranges where the Higgs – or a Higgs-like particl...

    2009-01-01

    The CMS experiment was completely assembled in the fall of 2008 after a decade of design, construction and commissioning. During the last two years cosmic ray data were taken on a regular basis. These data have enabled CMS to align the detector components, both spatially and temporally. Initial alignment using muons has established the relative alignment of the CMS tracking and muon systems. In addition, the CMS calorimetry has been crosschecked with test beam data thus providing an initial energy calibration of CMS calorimetry to about 5 per cent. The CMS magnet has been powered and field mapped. The trigger and data acquisition systems have been installed and run at full speed. The tiered data analysis system has been exercised at full design bandwidth for Tier0, Tier1 and Tier2 sites. Monte Carlo simulation of the CMS detector has been constructed at a detailed geometric level and has been tuned to test beam and other production data to provide a realistic model of the CMS detector.

The system promotes the distribution of the decision making and responsibilities to lower levels in the organisation by providing a state-of-the-art system to formalise the external commitments of the work packages without limiting their ability to modify their internal schedules to best meet their commitments. The system lets the project management focus on the interfaces between the work packages and alerts the management immediately if a conflict arises. The proposed system simplifies the planning and management process and eliminates the need for a large, centralised project management system.

  3. Constraining nuclear PDFs with CMS

    Chapon, Emilien

    2017-01-01

    Nuclear parton distribution functions are essential to the understanding of proton-lead collisions. We will review several measurements from CMS that are particularly sensitive to nPDFs. W and Z bosons are medium-blind probes of the initial state of the collisions, and we will present the measurements of their production cross sections in pPb collisions at 5.02 TeV, and as well a asymmetries with an increased sensitivity to nPDFs. We will also report measurements of charmonium production, including the nuclear modification factor of J/$\\psi$ and $\\psi$(2S) in pPb collisions at 5.02 TeV, though other cold nuclear matter effects may also be at play in those processes. At last, we will present measurements of the pseudorapidity of dijets in pPb collisions at 5.02 TeV.

    The alignment of the Strip and Pixel Tracker of the Compact Muon Solenoid experiment, with its large number of independent silicon sensors and its excellent spatial resolution, is a complex and challenging task. Besides high precision mounting, survey measurements and the Laser Alignment System, track-based alignment is needed to reach the envisaged precision.\\\\ Three different algorithms for track-based alignment were successfully tested on a sample of cosmic-ray data collected at the Tracker Integration Facility, where 15\\% of the Tracker was tested. These results, together with those coming from the CMS global run, will provide the basis for the full-scale alignment of the Tracker, which will be carried out with the first \\emph{p-p} collisions.

    Higgs mechanism. There are various hints at deviations from the Standard Model expectation which have been observed recently by Tevatron experiments in top final states. Several signatures of new physics accessible at the LHC either suffer from top-quark production as a significant background or contain top quarks themselves. In this talk, we present results on top quark physics obtained from the first LHC data collected by the CMS experiment.They include measurements of the top pair production cross section in various channels and their combination, measurements of the top quark mass, the single top cross section, a search for new particles decaying into top pairs, and a first look at the charge asymmetry.

    The data management elements in CMS are scalable, modular, and designed to work together. The main components are PhEDEx, the data transfer and location system; the Data Booking Service (DBS), a metadata catalog; and the Data Aggregation Service (DAS), designed to aggregate views and provide them to users and services. Tens of thousands of samples have been cataloged and petabytes of data have been moved since the run began. The modular system has allowed the optimal use of appropriate underlying technologies. In this contribution we will discuss the use of both Oracle and NoSQL databases to implement the data management elements as well as the individual architectures chosen. We will discuss how the data management system functioned during the first run, and what improvements are planned in preparation for 2015.

    The flavour changing neutral current decays can be interesting probes for searching for New Physics. Angular distributions of the decay $\\mathrm{B}^0 \\to \\mathrm{K}^{*0} \\mu^ +\\mu^-$ are studied using a sample of proton-proton collisions at $\\sqrt{s} = 8~\\mathrm{TeV}$ collected with the CMS detector at the LHC, corresponding to an integrated luminosity of $20.5~\\mathrm{fb}^{-1}$. An angular analysis is performed to determine $P_1$ and $P_5'$, where $P_5'$ is of particular interest due to recent measurements that indicate a potential discrepancy with the standard model. Based on a sample of 1397 signal events, $P_1$ and $P_5'$ angular parameters are determined as a function of the dimuon invariant mass squared. The measurements are in agreement with standard model predictions.

  11. LHCC COMPREHENSIVE REVIEW OF CMS (JULY 07)

    CERN Multimedia

    Extract from the Draft Report 1. EXECUTIVE SUMMARY The CMS Collaboration has made significant progress towards producing a detector ready for LHC operation in 2008. The past year saw all sub-detector groups success fully produce high-quality components and modules, and integrate them into the final objects to be installed into the CMS magnet. Installation and commissioning of final components in the CMS UXC55 cavern are well-under-way. In particular, the heavy lowering of detector elements into the CMS experiment cavern is a major success. The new CMS master schedule V36 incorporates the revised LHC machine schedule and includes an optimized detector sequencing. In spite of various delays, it remains possible that CMS will have an initial detector ready to exploit the initial LHC run in spring 2008. Installation of the Electromagnetic Calorimeter End-Cap (EE) and Pre-shower (ES) detectors is scheduled to be completed no sooner than July 2008 and CMS now plans to install the complete Pixel Detector for ...

  12. CMS centres worldwide: A new collaborative infrastructure

    2010-01-01

    The CMS Experiment at the LHC is establishing a global network of inter-connected 'CMS Centres' for controls, operations and monitoring. These support: (1) CMS data quality monitoring, detector calibrations, and analysis; and (2) computing operations for the processing, storage and distribution of CMS data. We describe the infrastructure, computing, software, and communications systems required to create an effective and affordable CMS Centre. We present our highly successful operations experiences with the major CMS Centres at CERN, Fermilab, and DESY during the LHC first beam data-taking and cosmic ray commissioning work. The status of the various centres already operating or under construction in Asia, Europe, Russia, South America, and the USA is also described. We emphasise the collaborative communications aspects. For example, virtual co-location of experts in CMS Centres Worldwide is achieved using high-quality permanently-running 'telepresence' video links. Generic Web-based tools have been developed and deployed for monitoring, control, display management and outreach.

  13. A new visitor centre for CMS

    2001-01-01

    At the inauguration of the new CMS visitor centre. The CMS experiment inaugurated a new visitor centre at its Cessy site on 14 June. This will allow the thousands of people who come to CERN each year to follow the construction of one the Laboratory's flagship experiments first-hand. CERN receives over 20,000 visitors each year. Until recently, many of them were taken on a guided tour of one of the LEP experiments. With the closure of LEP, however, trips underground are no longer possible, and the Visits' Service has put in place a number of other itineraries (Bulletin 46/2000). Since the CMS detector will be almost entirely constructed in a surface hall, it is now taking a big share of the limelight. The CMS visitor centre has been built on a platform overlooking CMS construction. It contains a set of clear descriptive posters describing the experiment, along with a video projection showing animations and movies about CMS construction. In the coming weeks, a display of CMS detector elements will be added, as...

  6. SUSY searches in early CMS data

    International Nuclear Information System (INIS)

    Tricomi, A

    2008-01-01

    In the first year of data taking at LHC, the CMS experiment expects to collect about 1 fb -1 of data, which make possible the first searches for new phenomena. All such searches require however the measurement of the SM background and a detailed understanding of the detector performance, reconstruction algorithms and triggering. The CMS efforts are hence addressed to designing a realistic analysis plan in preparation to the data taking. In this paper, the CMS perspectives and analysis strategies for Supersymmetry (SUSY) discovery with early data are presented

    The CMS Masterclass enables high school students to analyse authentic CMS data. Students can draw conclusions on key ratios and particle masses by combining their analyses. In particular, they can use the ratio of W^+ to W^- candidates to probe the structure of the proton, they can find the mass of the Z boson, and they can identify additional particles including, tentatively, the Higgs boson. In the United States, masterclasses are part of QuarkNet, a long-term program that enables students and teachers to use cosmic ray and particle physics data for learning with an emphasis on data from CMS.

    Full Text Available Global climate change is causing the Mediterranean coastal area of Israel to gradually acquire tropical characteristics. Rising sea surface temperatures in the eastern Mediterranean basin have facilitated the introduction, settlement and establishment of hundreds of alien species (Zenetos et al. 2012. The vast majority of these exotic species are of Indo-Pacific origin. We report the occurrence of the genus Dichotomaria in the eastern Mediterranean on the basis of specimens identified as Dichotomaria cf. obtusata (J. Ellis & Solander Lamarck. Tetrasporophytes with sporangial initials were identified morphologically and confirmed molecularly using plastid rbcL sequences. We also discuss possible paths of introduction of this and other alien species into the Levantine Sea.

    2003-03-20

    R-Phycoerythrin (R-PE) is a protein acting as a photosynthetic accessory pigment in red algae (Rodophyta). This protein has gained importance in many biotechnological applications in food science, immunodiagnostic, therapy, cosmetics, protein and cell labelling, and analytical processes. In this paper we report on a new, one step procedure for the extraction and purification of R-PE from a new source: the Mediterranean red algae Corallina elongata Ellis & Solander. This red algae contains mainly R-PE and is suitable for the production in culture. No other contaminating phycobiliproteins could be detected in the extracts. The method we propose for the purification is based on the use of hydroxyapatite, a chromatographic resin that can be produced in the laboratory at very low cost and can be used batch-wise with large amounts of extracts, alternative to chromatography, and therefore can be scaled up. Both the yield and the purity of R-PE are very good.

    2014-01-01

    The fact that the null generators of a future Cauchy horizon are past-complete was first proved by Hawking and Ellis (1973 The Large Scale Structure of Spacetime (Cambridge: Cambridge University Press)). Then, Budzyński, Kondracki and Królak outlined a proof free from the error found in the original one (2000 New properties of Cauchy and event horizons arXiv:gr-qc/0011033). Now, Minguzzi has published his version of the proof (2014 J. Math. Phys. 55 082503), patching a previously unnoticed hole in the preceding two. I am not aware of any flaws in that last proof, but it is quite difficult. In this note, I present a simpler one. (note)

    Ellis-van Creveld syndrome (EVC) is an autosomal recessive disorder characterized by disproportionate dwarfism, polydactyly, and congenital heart disease. This rare disorder is found with increased frequency among the Old Order Amish community in Lancaster County, Pennsylvania. We have used linkage analysis to localize the gene responsible for the EVC phenotype in nine interrelated Amish pedigrees and three unrelated families from Mexico, Ecuador, and Brazil. We now report the linkage for the Ellisvan Creveld syndrome gene to markers on the distal short arm of human chromosome 4, with Z{sub max} = 6.91 at {theta} = 0.02 for marker HOX7, in a region proximal to the FGFR3 gene responsible for the achondroplasia phenotype. 17 refs., 2 figs., 1 tab.

    Full Text Available Ellis-van Creveld syndrome (EVC is a very rare genetic disorder that affects various tissues of ectodermal and mesodermal origin; patients with EVC present with typical oral deficiencies. The affected individuals are quite young at the time of oral evaluation. It is, therefore, important that these individuals are diagnosed and receive dental treatment at an early age for their physiologic and psychosocial well-being. Albeit there are numerous articles penned on the EVC, the treatise from an oral perspective is inadequate, covering only oral exhibitions and the preventive treatments. This article reviews the literature and serves as the first disquisition for oral rehabilitation of an EVC patient utilizing surgical, orthodontic, restorative, and prosthodontic management.

It is a syndrome affecting the Amish population of Pennsylvania in USA with prevalence rate of 1/5,000 live at birth. In non-Amish population, the birth prevalence is 7/1,000,000. The syndrome is characterized by bilateral postaxial polydactyly of the hands, chondrodysplasia of long bones resulting in acromesomelic dwarfism, ectodermal dysplasia affecting nails as well as teeth and congenital heart malformation. There were very rare reports of this syndrome in dentistry. The present case focuses on the striking and constant oral findings of these patients, which are the main diagnostic features of this syndrome. Since the oral manifestations affect the esthetic, speech, and jaw growth of the child, the dentists have an important role to play in proper management of such case.

  18. Mandibular Angle Fractures: A Clinical and Biomechanical Comparison-the Works of Ellis and Haug.

    Science.gov (United States)

    Haug, Richard H; Serafin, Bethany L

    2008-11-01

    In a series of articles spanning 8 years, Ed Ellis reviewed the clinical results of the treatment of 478 mandibular angle fractures managed by eight different techniques. During a series of benchtop investigations employing polyurethane synthetic mandible replicas, Rich Haug investigated the biomechanical behavior of approximately 15 different techniques designed to reconstruct mandibular angle fractures. This article reviews these two series of investigations in an attempt to gain insight into the biomechanical and biological factors that affect the successful reconstruction of mandibular angle fractures. It appears that the current techniques used to reconstruct mandibular angle fractures are sound from the standpoint of biomechanics within a range of forces encountered during clinical function. It also appears that an unsuccessful reconstruction is based on a biological result of a behavioral issue such as noncompliance, substance abuse, and/or nutritional or immune compromise.

Describing the electromagnetic (EM) environment of CMS is of major importance for determining and solving problems related to electromagnetic interference, grounding and shielding. This thesis addresses the EMC studies conducted for the CMS experiment to define the baseline of the future CMS EMC policy. The EMC study has been focused on the power supply distribution system. For that purpose, a simplified scheme of the power supply system has been used in this research work to address EMC studies. These studies are mainly focused on the quantification of the FEE sensitivity to conductive noise coupled through the input/output cables, the noise generated by power supplies and the noise propagation effects present in the detector. Also, the magnitude and effects of transient signals disturbing the power supply system are introduced.

    The CMS Regional Calorimeter Trigger (RCT) receives eight-bit energies and a data quality bit from the HCAL and ECAL Trigger Primitive Generators (TPGs). The RCT uses these trigger primitives to find e/γ candidates and calculate regional calorimeter sums that are sent to the Global Calorimeter Trigger (GCT) for sorting and further processing. The RCT hardware consists of one clock distribution crate and 18 double-sided crates containing custom boards, ASICs, and backplanes. The RCT electronics have been completely installed since 2007. The RCT has been integrated into the CMS Level-1 Trigger chain. Regular runs, triggering on cosmic rays, prepare the CMS detector for the restart of the LHC. During this running, the RCT control is handled centrally by CMS Run Control and Monitor System communicating with the Trigger Supervisor. Online Data Quality Monitoring (DQM) evaluates the performance of the RCT during these runs. Offline DQM allows more detailed studies, including trigger efficiencies. These and other r...

  4. The CMS "Higgs Boson Goose Game" Poster

    CERN Multimedia

    Davis, Siona Ruth

    Building and operating the CMS Detector is a complicated endeavour! Now, more than 20 years after the detector was conceived, the CMS Bologna group proposes to follow the steps of this challenging project by playing "The Higgs Boson Goose Game", illustrating CMS activities and goals. The concept of the game is inspired by the traditional "Game of the Goose". The underlying idea is that the progress of building and operating a detector at the LHC is similar to the progress of the pawns on the game board: it is fast at times, bringing rewards and satisfaction, while sometimes unexpected problems cause delays or even a step back requiring CMS scientists to use all of their skill and creativity to devise new solutions.

    This thesis describes hadron reconstruction at the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at CERN, Geneva. The focus is on the particle flow reconstruction of these objects. This thesis revisits the subject of the CMS calorimeters' non-linear response to hadrons. Data from testbeam experiments conducted in 2006 & 2007 is compared with simulations and substantial differences are found. A particle flow calibration to correct the energy response of the testbeam data is evaluated. The reconstructed jet response is found to change by ~ 5% when a data-driven calibration is used in place of the calibration derived from simulation. Collision data taken at the early stage of CMS' commissioning is also presented. The hadron response in data is determined to be compatible with testbeam results presented in this thesis. This thesis also details the use of neural networks to improve the energy measurement of hadrons at CMS. The networks are implemented in a functional and concurrent ...

    2002-01-01

    At the third awards ceremony to honour its top suppliers, the CMS collaboration presented awards to eight firms. Seven of them are involved in the manufacture of the magnet. The winners of the third CMS suppliers' awards visit the assembly site for the detector. Unsurprisingly, the CMS magnet was once again in the limelight at the third awards ceremony in honour of the collaboration's top suppliers. 'Unsurprisingly', because this magnet, which must produce an intense field of 4 Tesla inside an enormous volume (12 metres in diameter and 13 metres in length) is the detector's key component. As a result, many firms are involved in its construction. The CMS suppliers' awards are an annual event aimed at rewarding the exceptional efforts of certain companies. Firms are only eligible once they have delivered at least 50% of their supplies. This year, the collaboration honoured eight firms at a ceremony held on Monday 4 March in the main auditorium. Seven of th...

    The CMS Data Analysis School is an official event organized by the CMS Collaboration to teach students and post-docs how to perform a physics analysis. The school is coordinated by the CMS schools committee and was first implemented at the LHC Physics Center at Fermilab in 2010. As part of the training, there are a number of “short” exercises on physics object reconstruction and identification, Monte Carlo simulation, and statistical analysis, which are followed by “long” exercises based on physics analyses. Some of the long exercises go beyond the current state of the art of the corresponding CMS analyses. This paper describes the goals of the school, the preparations for a school, the structure of the training, and student satisfaction with the experience as measured by surveys.

    2015-01-01

    The Condition Database plays a key role in the CMS computing infrastructure. The complexity of the detector and the variety of the sub-systems involved are setting tight requirements for handling the Conditions. In the last two years the collaboration has put an effort in the re-design of the Condition Database system, with the aim to improve the scalability and the operability for the data taking starting in 2015. The re-design has focused in simplifying the architecture, using the lessons learned during the operation of the previous data-taking period. In the new system the relational features of the database schema are mainly exploited to handle the metadata ( Tag and Interval of Validity ), allowing for a limited and controlled set of queries. The bulk condition data ( Payloads ) are stored as unstructured binary data, allowing the storage in a single table with a common layout for all of the condition data types. In this presentation, we describe the full architecture of the system, including the serv...

    One of the world’s largest physics experiments has just had a change in leadership. This is a chance for the collaboration to take stock of the tremendous work done for LS1 and to prepare for the challenges that lie ahead.   From left to right: Kerstin Borras, Tiziano Camporesi and Paris Sphicas. “The keyword is teamwork. That’s the only way you can effectively manage a large number of extremely talented and motivated people,” says Tiziano Camporesi who took the reins of the CMS collaboration at the beginning of the year. The recipe might seem easier on paper than in practice. However, given his 28 years at CERN, two of which he spent as the head of the DELPHI collaboration, Camporesi has extensive experience in managing large scientific collaborations and success in this respect is well within his reach: “I have learned many lessons from the past and I believe that building consensus is instrumental to successful leadership.” The C...

    2016-01-01

    Two- and multi-particle angular correlations in pp, pPb and PbPb collisions at the LHC energies are presented as a function of centrality, charged-particle multiplicity and transverse momentum ($p_{T}$). The data were collected using the CMS detector. The Fourier coefficents in PbPb collisions are measured over an extended $p_{T}$ range up to 100 GeV/c. These $v_{n}$ measurements at high-$p_{T}$ are complementary to the $R_{AA}$ measurements. The elliptic flow of charged and strange particles and the triangular flow of charged particles in pp collisions is measured using the two-particle correlations. A clear mass ordering effect is observed for low-$p_{T}$ $v_{2}$ values. For the first time, in 13 TeV pp collisions, the $v_{2}$ is extracted from four- and six-particle correlations, and is comparable to the $v_{2}$ from two-particle correlations. This supports the collective nature of the long-range correlations in high-multiplicity pp collisions. A Principle Component Analysis (PCA) of two-particle correlati...

  1. CMS kinematic edge from sbottoms

    Huang, Peisi; Wagner, Carlos E. M.

    2015-01-01

    We present two scenarios in the Minimal Supersymmetric Extension of the Standard Model (MSSM) that can lead to an explanation of the excess in the invariant mass distribution of two opposite charged, same flavor leptons, and the corresponding edge at an energy of about 78 GeV, recently reported by the CMS Collaboration. In both scenarios, sbottoms are pair produced, and decay to neutralinos and a b-jet. The heavier neutralinos further decay to a pair of leptons and the lightest neutralino through on-shell sleptons or off-shell neutral gauge bosons. These scenarios are consistent with the current limits on the sbottoms, neutralinos, and sleptons. Assuming that the lightest neutralino is stable we discuss the predicted relic density as well as the implications for darkmatter direct detection. We show that consistency between the predicted and the measured value of the muon anomalous magnetic moment may be obtained in both scenarios. Finally, we define the signatures of these models that may be tested at the 13 TeV run of the LHC

    The CMS experiment has collected an enormous volume of metadata about its computing operations in its monitoring systems, describing its experience in operating all of the CMS workflows on all of the Worldwide LHC Computing Grid Tiers. Data mining efforts into all these information have rarely been done, but are of crucial importance for a better understanding of how CMS did successful operations, and to reach an adequate and adaptive modelling of the CMS operations, in order to allow detailed optimizations and eventually a prediction of system behaviours. These data are now streamed into the CERN Hadoop data cluster for further analysis. Specific sets of information (e.g. data on how many replicas of datasets CMS wrote on disks at WLCG Tiers, data on which datasets were primarily requested for analysis, etc) were collected on Hadoop and processed with MapReduce applications profiting of the parallelization on the Hadoop cluster. We present the implementation of new monitoring applications on Hadoop, and discuss the new possibilities in CMS computing monitoring introduced with the ability to quickly process big data sets from mulltiple sources, looking forward to a predictive modeling of the system.

    The Compact Muon Solenoid (CMS) is a general-purpose detector designed to run at the highest luminosity at the CERN Large Hadron Collider (LHC). Its distinctive featuresinclude a 4 T superconducting solenoid with 6 m diameter by 12.5 m long free bore, enclosed inside a 10000-ton return yoke made of construction steel. Accurate characterization of the magnetic field everywhere in the CMS detector is required. During two major tests of the CMS magnet the magnetic flux density was measured inside the coil in a cylinder of 3.448 m diameter and 7 m length with a specially designed field-mapping pneumatic machine as well as in 140 discrete regions of the CMS yoke with NMR probes, 3-D Hall sensors and flux-loops. A TOSCA 3-D model of the CMS magnet has been developed to describe the magnetic field everywhere outside the tracking volume measured with the field-mapping machine. A volume based representation of the magnetic field is used to provide the CMS simulation and reconstruction software with the magnetic field ...

    The CMS experiment has adopted a computing system where resources are distributed worldwide in more than 50 sites. The operation of the system requires a stable and reliable behaviour of the underlying infrastructure. CMS has established procedures to extensively test all relevant aspects of a site and their capability to sustain the various CMS computing workflows at the required scale. The Site Readiness monitoring infrastructure has been instrumental in understanding how the system as a whole was improving towards LHC operations, measuring the reliability of sites when running CMS activities, and providing sites with the information they need to troubleshoot any problem. This contribution reviews the complete automation of the Site Readiness program, with the description of monitoring tools and their inclusion into the Site Status Board (SSB), the performance checks, the use of tools like HammerCloud, and the impact in improving the overall reliability of the Grid from the point of view of the CMS computing system. These results are used by CMS to select good sites to conduct workflows, in order to maximize workflows efficiencies. The performance against these tests seen at the sites during the first years of LHC running is as well reviewed.

    The National Library of Australia (NLA) Australian Newspapers project went public in July 2008, but many historians and researchers are as yet unaware of its existence, or of its great potential for their research. This article will demonstrate the revolutionary potential of this project for the history of medicine in Australia. Using the case ofa largely-forgotten Western Australian chemist, dentist, and optician, Harcourt Whipple Ellis, a search of the NLA Australian Newspapers project produces a substantial amount of information on his at times scandalous career, a general physical description, a verbatim quotation, and many other witnesses statements attributed to him. These newspaper articles flesh out' Ellis, and also provide valuable insights into early-twentieth-century life in Perth.

    There are few systematic studies on the prevalence of sarcopenia using the new diagnostic criteria in different geriatric care settings. To estimate the prevalence of sarcopenia, using the European Working Group on Sarcopenia in Older People (EWGSOP) criteria in older subjects living in nursing homes and in those who attend geriatric outpatient clinics. A single country multicentre study in two samples of older subjects: patients cared for in outpatient geriatric clinics, and individuals living in nursing homes. Data collected will include demographic variables, medical history, medication, geriatric syndromes, functional status (assessment of basic and instrumental activities of daily living), mobility, cognitive status, comorbidity, quality of life, nutritional status, and laboratory parameters. For the diagnosis of sarcopenia, 4m walking speed, handgrip strength, and body composition measured by bioelectrical impedance analysis will be assessed. Using the EWGSOP algorithm, the prevalence of sarcopenia in an elderly Spanish population will be estimated. In addition, concordance and correlation between the three parameters included in the definition (muscle mass, muscle strength, and physical performance) will be analysed, using the different existing cut-off points, and examining the diagnostic accuracy of each. Finally, demographic, anthropometric and functional data that define subjects with sarcopenia will be investigated. The ELLI study should improve knowledge on the prevalence and characteristics of sarcopenia in older people in our population. Copyright © 2012 SEGG. Published by Elsevier Espana.

    Little is known on growth, growth hormone (GH) levels and GH treatment in patients with Ellis-van Creveld syndrome (EvC). The aim of the present study was to assess growth, growth hormone status and the possible effectiveness of GH treatment in literature and in a small series of EvC patients. A review of literature indicated retarded growth for most EvC patients (-2 to -4.5 SDS) and minimal data on GH levels or treatment which did not allow any conclusion. We studied eight EvC patients, seven of whom were treated with GH. Four were GH deficient (GHD) and four were GH sufficient. In all patients treated with GH, first year growth velocity increased. In three of the four GHD and in one GH-sufficient patient a gain in height SDS was noted. In the present small EvC series GHD occurred more often than expected. Patient acquisition through the Growth Hormone Database will have caused a significant bias, but the present results indicate that GH treatment may improve growth in at least some patients with EvC. Therefore we conclude that EvC patients may benefit from being tested for GHD and, if indicated, treated. In addition a prospective study to evaluate GH status and linear growth in patients with EvC as well as the potential effectiveness of GH treatment is warranted. (c) 2007 Wiley-Liss, Inc.

    Ellis-van Creveld syndrome (EvC, MIM 225500) is an autosomal recessive skeletal dysplasia characterized by short limbs, short ribs, postaxial polydactyly and dysplastic nails and teeth. Congenital cardiac defects, most commonly a defect of primary atrial septation producing a common atrium, occur in 60% of affected individuals. The disease was mapped to chromosome 4p16 in nine Amish subpedigrees and single pedigrees from Mexico, Ecuador and Brazil. Weyers acrodental dysostosis (MIM 193530), an autosomal dominant disorder with a similar but milder phenotype, has been mapped in a single pedigree to an area including the EvC critical region. We have identified a new gene (EVC), encoding a 992-amino-acid protein, that is mutated in individuals with EvC. We identified a splice-donor change in an Amish pedigree and six truncating mutations and a single amino acid deletion in seven pedigrees. The heterozygous carriers of these mutations did not manifest features of EvC. We found two heterozygous missense mutations associated with a phenotype, one in a man with Weyers acrodental dysostosis and another in a father and his daughter, who both have the heart defect characteristic of EvC and polydactyly, but not short stature. We suggest that EvC and Weyers acrodental dysostosis are allelic conditions.

    Ellis-van Creveld (EvC) syndrome is a rare autosomal recessive malformation syndrome with the main features cardiac defects, postaxial hexadactyly, mesomelic shortening of the limbs, short ribs, dysplastic nails and teeth, oral frenula and various other abnormalities while mental function is normal. We describe 2 adult EvC patients with the cardinal skeletal features of mesomelic short stature and severe, progressive genu valgum deformity, resulting from loss of function mutations in the EVC genes. While the genu valgum was the predominating and disabling feature in patient 1, patient 2 showed acroosteolyses in the distal phalanges and a symmetrical synostosis of metacarpals in his hands. Moreover, patient 2 developed synostoses in the additional fingers in adolescence which had not been present at the age of 12 years, suggesting a further progression of skeletal disease. Joint fusion of phalanges so far has not been reported in EvC syndrome. Our data further expand the phenotypic spectrum of EvC related skeletal malformations and contribute important new information on the clinical course of EvC syndrome with increasing age.

  1. Ellis-van Creveld with an Unusual Dental Anomaly: A Case Report.

    Nethan, Suzanne Tanya; Sinha, Shruti; Chandra, Sunira

    2017-09-01

    The Ellis-van Creveld (EVC) syndrome is a chondroectodermal dysplasia and is characterized by the cardinal features of disproportionate short stature, polydactyly, hidrotic ectodermal dysplasia, and congenital heart malformations, along with other skeletal and dental abnormalities. It is a rare condition, with very few cases reported in the medical literature. It is inherited as an autosomal recessive disorder with variable expressions, due to the mutation of the EVC syndrome 1 and 2 genes, which are located on chromosome 4p16. The present case report describes the EVC syndrome in a 14-year-old girl, who presented with a tetrad of all the cardinal features and other associated features. Additional unusual dental findings such as single-rooted funnel-shaped molars, reduced crown size, enamel hypoplasia, supernumerary teeth, dental fusion, taurodontism, abnormal occlusal anatomy with wide grooves, and atypical cusps have been reported in most previous cases of this syndrome. However, in our patient, surprisingly, the teeth present were relatively non-anomalous, both clinically and radiographically (i.e., with none of the usually found abnormalities mentioned above). The only abnormal dental findings were those of absent maxillary and mandibular incisors (including impacted permanent incisors) and mild malocclusion, a novel point of this case.

    Ellis-van Creveld (EVC) syndrome is a rare autosomal recessive disorder characterized by hypoplastic nails, polydactyly, and achondroplasia. Patients usually exhibit normal cognitive function and no remarkable developmental delay. We herein present an unusual case of EVC syndrome. A Japanese 2-year-old boy was born at term, but immediately developed severe respiratory failure due to thorax deformity, postaxial polydactyly and nail hypoplasia. We identified a novel pattern of germinal compound heterozygous nonsense EVC2 mutations of c.1814C > A (p. S605X) and c.2653C > T (p. R885X), leading to the diagnosis of EVC syndrome. Interestingly, he also had severe developmental delay, and suddenly developed excessive abdominal distension at the age of 2. On surgery, extensive necrotic bowel with chronic intestinal pseudo-obstruction was noted. This is, to our knowledge, a most severe phenotype of EVC syndrome, illustrating that the specific pattern of EVC2 compound heterozygous mutations may cause severe developmental delay and intestinal malfunction. © 2016 Japan Pediatric Society.

    Mutations identified in a cohort of patients with atrioventricular septal defects as a part of Ellis van Creveld syndrome (EvC syndrome) led us to study the role of two non-homologous genes, EVC and LBN, in heart development and disease pathogenesis. To address the cause of locus heterogeneity resulting in an indistinguishable heart-hand phenotype, we carried out in situ hybridization and immunofluorescence and identified co-localization of Evc and Lbn mRNA and protein. In the heart, expression was identified to be strongest in the secondary heart field, including both the outflow tract and the dorsal mesenchymal protrusion, but was also found in mesenchymal structures of the atrial septum and the atrioventricular cushions. Finally, we studied the transcriptional hierarchy of EVC and LBN but did not find any evidence of direct transcriptional interregulation between the two. Due to the locus heterogeneity of human mutations predicted to result in a loss of protein function, a bidirectional genomic organization and overlapping expression patterns, we speculate that these proteins function coordinately in cardiac development and that loss of this coordinate function results in the characteristics of EvC syndrome.

    Bloom, Kenneth Arthur

    2014-01-01

    CMS is in the process of deploying an Xrootd based infrastructure to facilitate a global data federation. The services of the federation are available to export data from half the physical capacity and the majority of sites are configured to read data over the federation as a back-up. CMS began with a relatively modest set of use-cases for recovery of failed local file opens, debugging and visualization. CMS is finding that the data federation can be used to support small scale analysis and load balancing. Looking forward we see potential in using the federation to provide more flexibility in the location workflows are executed as the differenced between local access and wide area access are diminished by optimization and improved networking. In this presentation we will discuss the application development work and the facility deployment work, the use-cases currently in production, and the potential for the technology moving forward.

  6. An online radiation monitoring system for CMS

    Camanzi, Barbara

    2004-01-01

    The Large proton-proton cross-section at 14 TeV and the high luminosity of the LHC will expose CMS to a very complex radiation environment which consists of many different particles. Some electronic components and materials will be exposed to doses of radiation never faced before. CMS must operate reliably for many years in this high-intensity, mixed radiation field. Early warning of problems caused by these high doses is provided by regular and quantitative monitoring of the radiation absorbed at key points by a carefully designed array of remote-reading dosimeters, centred largely on CMS subdetectors. In this note the suitable, existing dosimetric technologies are evaluated. To be suitable the system must perform online monitoring of the radiation environment and have an extremely high dynamic range. The testing of three dosimetric principles is described.

    The CMS tracker is the largest silicon detector ever built, covering 200 square meters and providing an average of 14 high-precision measurements per track. Tracking is essential for the reconstruction of objects like jets, muons, electrons and tau leptons starting from the raw data from the silicon pixel and strip detectors. Track reconstruction is widely used also at trigger level as it improves objects tagging and resolution.The CMS tracking code is organized in several levels, known as iterative steps, each optimized to reconstruct a class of particle trajectories, as the ones of particles originating from the primary vertex or displaced tracks from particles resulting from secondary vertices. Each iterative step consists of seeding, pattern recognition and fitting by a kalman filter, and a final filtering and cleaning. Each subsequent step works on hits not yet associated to a reconstructed particle trajectory.The CMS tracking code is continuously evolving to make the reconstruction computing load compat...

    2008-11-01

    CMS is using Geant4 to simulate the detector setup for the forthcoming data from the LHC. Validation of physics processes inside Geant4 is a major concern in view of getting a proper description of jets and missing energy for signal and background events. This is done by carrying out an extensive studies with test beam using the prototypes or real detector modules of the CMS calorimeter. These data are matched with Geant4 predictions using the same framework that is used for the entire CMS detector. Tuning of the Geant4 models is carried out and steps to be used in reproducing detector signals are defined in view of measurements of energy response, energy resolution, transverse and longitudinal shower profiles for a variety of hadron beams over a broad energy spectrum between 2 to 300 GeV/c. The tuned Monte Carlo predictions match many of these measurements within systematic uncertainties.

    Fireworks is a CMS event display which is specialized for the physics studies case. This specialization allows us to use a stylized rather than 3D-accurate representation when appropriate. Data handling is greatly simplified by using only reconstructed information and ideal geometry. Fireworks provides an easy-to-use interface which allows a physicist to concentrate only on the data in which he is interested. Data is presented via graphical and textual views. Fireworks is built using the Eve subsystem of the CERN ROOT project and CMS's FWLite project. The FWLite project was part of CMS's recent code redesign which separates data classes into libraries separate from algorithms producing the data and uses ROOT directly for C++ object storage, thereby allowing the data classes to be used directly in ROOT.

    The very heart of any LHC experiment is not a pixel detector, nor a vertex locator but a beam pipe. It is the site of each collision and the boundary where the accelerator and experiment meet. As an element of complex design and manufacture the CMS beam pipe was fifteen years in the making and finally fully installed on Tuesday 10 June. Watch the video! End cap beam pipe installation in the CMS detector. Central beam pipe installation.The compensation modules were the final pieces to take their places in the cavern at Point 5: "These are like bellows," says Wolfram Zeuner, Deputy Technical Co-ordinator for CMS. "They allow us to compensate for the change in length when we heat or cool the beam pipe. And they are the very last elements; beam pipe installation, which began last year, is now complete." The beam pipe is neither too fragile nor too bulky, but just right to satisfy the conflicting n...

  13. Deep learning in jet reconstruction at CMS

    Stoye, Markus

    2017-01-01

    Deep learning has led to several breakthroughs outside the field of high energy physics, yet in jet reconstruction for the CMS experiment at the CERN LHC it has not been used so far. This report shows results of applying deep learning strategies to jet reconstruction at the stage of identifying the original parton association of the jet (jet tagging), which is crucial for physics analyses at the LHC experiments. We introduce a custom deep neural network architecture for jet tagging. We compare the performance of this novel method with the other established approaches at CMS and show that the proposed strategy provides a significant improvement. The strategy provides the first multi-class classifier, instead of the few binary classifiers that previously were used, and thus yields more information and in a more convenient way. The performance results obtained with simulation imply a significant improvement for a large number of important physics analysis at the CMS experiment.

  14. CMS standard model Higgs boson results

    2013-11-01

    Full Text Available In July 2012 CMS announced the discovery of a new boson with properties resembling those of the long-sought Higgs boson. The analysis of the proton-proton collision data recorded by the CMS detector at the LHC, corresponding to integrated luminosities of 5.1 fb−1 at √s = 7 TeV and 19.6 fb−1 at √s = 8 TeV, confirm the Higgs-like nature of the new boson, with a signal strength associated with vector bosons and fermions consistent with the expectations for a standard model (SM Higgs boson, and spin-parity clearly favouring the scalar nature of the new boson. In this note I review the updated results of the CMS experiment.

    The objective of this study was to compare two different nebulizers: Eflow rapid® and Pari LC star® by scintigraphy and PK modeling to simulate epithelial lining fluid concentrations from measured plasma concentrations, after nebulization of CMS in baboons. Three baboons received CMS by IV infusion and by 2 types of aerosols generators and colistin by subcutaneous infusion. Gamma imaging was performed after nebulisation to determine colistin distribution in lungs. Blood samples were collected during 9 h and colistin and CMS plasma concentrations were measured by LC-MS/MS. A population pharmacokinetic analysis was conducted and simulations were performed to predict lung concentrations after nebulization. Higher aerosol distribution into lungs was observed by scintigraphy, when CMS was nebulized with Pari LC® star than with Eflow Rapid® nebulizer. This observation was confirmed by the fraction of CMS deposited into the lung (respectively 3.5% versus 1.3%).CMS and colistin simulated concentrations in epithelial lining fluid were higher after using the Pari LC star® than the Eflow rapid® system. A limited fraction of CMS reaches lungs after nebulization, but higher colistin plasma concentrations were measured and higher intrapulmonary colistin concentrations were simulated with the Pari LC Star® than with the Eflow Rapid® system.

    2010-04-01

    The CMS CERN Analysis Facility (CAF) was primarily designed to host a large variety of latency-critical workflows. These break down into alignment and calibration, detector commissioning and diagnosis, and high-interest physics analysis requiring fast-turnaround. In addition to the low latency requirement on the batch farm, another mandatory condition is the efficient access to the RAW detector data stored at the CERN Tier-0 facility. The CMS CAF also foresees resources for interactive login by a large number of CMS collaborators located at CERN, as an entry point for their day-by-day analysis. These resources will run on a separate partition in order to protect the high-priority use-cases described above. While the CMS CAF represents only a modest fraction of the overall CMS resources on the WLCG GRID, an appropriately sized user-support service needs to be provided. We will describe the building, commissioning and operation of the CMS CAF during the year 2008. The facility was heavily and routinely used by almost 250 users during multiple commissioning and data challenge periods. It reached a CPU capacity of 1.4MSI2K and a disk capacity at the Peta byte scale. In particular, we will focus on the performances in terms of networking, disk access and job efficiency and extrapolate prospects for the upcoming LHC first year data taking. We will also present the experience gained and the limitations observed in operating such a large facility, in which well controlled workflows are combined with more chaotic type analysis by a large number of physicists.

    The tracking system of the CMS detector provides excellent resolution for charged particle tracks and an efficient way of tagging jets. In order to reconstruct good quality tracks, the position and orientation of each silicon pixel and strip modules need to be determined with a precision of several micrometers. The performance of the CMS tracker alignment in 2016 using cosmic-ray data recorded at 0 T magnetic field and proton-proton collision data recorded at 3.8 T magnetic field has been studied. The data-driven validation of the results are presented. The time-dependent movement of the pixel detector's large-scale structure is demonstrated.

    The CMS experiment, to be installed at the future p-p collider LHC at CERN, foresees the use of Micro-Strip Gas Counters ( MSGC's) for the outer layers of its central tracker. Present developments focus on the reliability of MSGC's in the harsh radiation environment imposed by the LHC. This paper reports on tests of two baseline CMS MSGC's identical to those foreseen for the barrel part of the tracker, in a high intensity pion beam at the Paul Scherrer Institute ( PSI), in april 1999.

  5. CMS Silicon Strip Tracker Operation and Performance

    Boudoul, Gaelle

    2011-01-01

    The Silicon Strip Tracker (SST) of the CMS experiment is, with 9.6 million readout channels, the largest strip tracker ever built. In order to correctly interpret and reconstruct the events recorded it needs to be precisely calibrated, thus ensuring that it fully contributes to the physics research program of the CMS experiment. In 2009 and 2010, the performance of the SST has been carefully studied using cosmic muons and tracks from proton-proton collisions at centre-of-mass energies of 900 GeV, 2.36 TeV and 7 TeV. In this paper, we present some results of the detector performance.

    The CMS Tracker is the largest Silicon detector ever built, covering 200 square meters and providing an average of 14 high-precision measurements per track. Track reconstruction is based on an iterative algorithm designed to optimize efficiency and estimation of track parameters. The alignment procedures and their performances are presented. Tracking and b-tagging primitives are typically validated by using data-driven methods. Selected examples are discussed. The CMS Tracker is also capable of reliable energy loss measurement and of effective reconstruction of photon conversions and nuclear interactions. Application examples of these features are given.

  14. The grand descent has begun for CMS

    CERN Multimedia

    2006-01-01

    Until recently, the CMS experimental cavern looked relatively empty; its detector was assembled entirely at ground level, to be lowered underground in 15 sections. On 2 November, the first hadronic forward calorimeter led the way with a grand descent. The first section of the CMS detector (centre of photo) arriving from the vertical shaft, viewed from the cavern floor. There is something unusual about the construction of the CMS detector. Instead of being built in the experimental cavern, like all the other detectors in the LHC experiments, it was constructed at ground level. This was to allow for easy access during the assembly of the detector and to minimise the size of the excavated cavern. The slightly nerve-wracking task of lowering it safely into the cavern in separate sections came after the complete detector was successfully tested with a magnetic field at ground level. In the early morning of 2 November, the first section of the CMS detector began its eagerly awaited descent into the underground ca...

    2001-01-01

    In order to motivate the hundreds of companies building their detectors, the CMS and ATLAS collaborations have recently been handing out awards of excellence to their top suppliers. At its second ceremony of this kind, CMS honoured four of its suppliers, while ATLAS for the first time paid tribute to two of its contractors. The atmosphere in the Council Chamber was festive rather than formal at the start of CMS week on Monday 5 March. Before embarking upon a long series of seminars and presentations, the Collaboration held its second awards ceremony to honour its top suppliers. By paying tribute to the exceptional efforts of certain suppliers, the Collaboration's aim is to motivate all the firms, some 500 in total, taking part in the experiment's construction. The CMS Awards panel thus singles out contractors who have not only provided full satisfaction in terms of compliance with specifications, quality and deadlines, but have in addition provided original solutions to delicate problems. Four firms came away...

    2009-08-01

    The CMS experiment will collect data from the proton-proton collisions delivered by the Large Hadron Collider (LHC) at a centre-of-mass energy up to 14 TeV. The CMS trigger system is designed to cope with unprecedented luminosities and LHC bunch-crossing rates up to 40 MHz. The unique CMS trigger architecture only employs two trigger levels. The Level-1 trigger is implemented using custom electronics, while the High Level Trigger (HLT) is based on software algorithms running on a large cluster of commercial processors, the Event Filter Farm. We present the major functionalities of the CMS High Level Trigger system as of the starting of LHC beams operations in September 2008. The validation of the HLT system in the online environment with Monte Carlo simulated data and its commissioning during cosmic rays data taking campaigns are discussed in detail. We conclude with the description of the HLT operations with the first circulating LHC beams before the incident occurred the 19th September 2008.

    CERN Document Server

    CMS Collaboration

    2015-01-01

    The CMS Beam Halo Monitor has been successfully installed in the CMS cavern in LHC Long Shutdown 1 for measuring the machine induced background for LHC Run II. The system is based on 40 detector units composed of radiation hard synthetic quartz Cherenkov radiators coupled to fast photomultiplier tubes for a direction sensitive measurement. The readout electronics chain uses many components developed for the Phase 1 upgrade to the CMS Hadronic Calorimeter electronics, with dedicated firmware and readout adapted to the beam monitoring requirements. The PMT signal is digitized by a charge integrating ASIC (QIE10), providing both the signal rise time, with few ns resolution, and the charge integrated over one bunch crossing. The backend electronics uses microTCA technology and received data via a high-speed 5 Gbps asynchronous link. It records histograms with sub-bunch crossing timing resolution and is readout by IPbus using the newly designed CMS data acquisition for non-event based data. The data is processed i...

    2015-01-01

    A new Beam Halo Monitor (BHM) detector system has been installed in the CMS cavern to measure the machine-induced background (MIB) from the LHC. This background originates from interactions of the LHC beam halo with the final set of collimators before the CMS experiment and from beam gas interactions. The BHM detector uses the directional nature of Cherenkov radiation and event timing to select particles coming from the direction of the beam and to suppress those originating from the interaction point. It consists of 40 quartz rods, placed on each side of the CMS detector, coupled to UV sensitive PMTs. For each bunch crossing the PMT signal is digitized by a charge integrating ASIC and the arrival time of the signal is recorded. The data are processed in real time to yield a precise measurement of per-bunch-crossing background rate. This measurement is made available to CMS and the LHC, to provide real-time feedback on the beam quality and to improve the efficiency of data taking. In this talk we will describ...

    The Ellis-van Creveld (EVC) gene is associated with various congenital heart diseases. However, studies on EVC gene variations in ventricular septal defect (VSD) and the underlying molecular mechanisms are sparse. The present study detected 11 single-nucleotide polymorphisms (SNPs) in 65 patients with VSD and 210 control patients from the Chinese Han population. Of the identified SNPs only the c.1727G>A SNP site was positively associated with the development of VSD (PG, was also identified, which causes a leucine to valine substitution at amino acid 115 of the EVC protein (p.L115V). The results of functional prediction indicated that c.343C>G may be a pathogenic mutation. In addition, in NIH3T3 mouse embryonic fibroblast cells, the EVC c.343C>G mutation significantly decreased cell proliferation and increased apoptosis. Further investigation demonstrated that in NIH3T3 cells, overexpression of EVC c.343C>G mutation reduced the binding between EVC and smoothened, which further downregulated the activity of the hedgehog (Hh) signaling pathway and the expression of downstream cyclin D1 and B-cell lymphoma 2 proteins with SAG. The c.1727G>A SNP of the EVC gene increased VSD susceptibility in patients from the Chinese Han population. The molecular mechanism underlying the development of VSD induced by the EVC c.343C>G mutation may be due to a reduction in the anti-apoptotic and proliferative abilities of cardiomyocytes via downregulation of Hh pathway activity. The results of the present study may provide novel targets for the diagnosis and treatment of patients with VSD. PMID:29257216

  18. Ellis-van Creveld syndrome and congenital heart defects: presentation of an additional 32 cases.

    2011-10-01

    Ellis-van Creveld (EVC) syndrome is a rare genetic abnormality that has been linked to a mutation in the EVC or EVC2 genes. Common atrium (CA) is an uncommon cardiac malformation, and yet it is commonly found in patients with EVC. We performed a retrospective review of the cases submitted to the Pediatric Cardiac Care Consortium (PCCC) between 1982 and 2007. A review of the English-language literature for previously published cases, as well as current genetic research findings, was also performed. Thirty-two pediatric patients with congenital heart disease (CHD) and EVC syndrome were identified in the PCCC database. Twenty-eight (88%) had an endocardial cushion defect, with 15 of these having primary failure of atrial septation resulting in CA. Persistent left superior vena cava (LSVC) and pulmonary venous connection abnormalities were common. The incidence of persistent LSVC and pulmonary venous abnormalities were greater than previously reported for patients with EVC. Our study reviews the reported literature and adds 32 additional cases from the PCCC database. Review of the cardiac phenotype in patients with EVC syndrome reveals a characteristic pattern of atrioventricular canal defects with systemic and pulmonary venous abnormalities. The frequent association of these abnormalities is strongly reminiscent of the cardiac phenotype found in patients with heterotaxy syndromes. Emerging molecular and developmental studies suggest that EVC and EVC2 proteins may be important for cilia function, which is implicated in the pathogenesis of heterotaxy syndromes. It is speculated that coordinate function between the EVC proteins is required for a cilia-dependent cardiac morphogenesis.

    Full Text Available Abstract Background Ellis-van Creveld (EvC syndrome is an autosomal recessive chondrodysplastic condition with clinical manifestations that include short-limbs and ribs, postaxial polydactyly and dysplastic nails and teeth. In about two thirds of patients, mutations in either EVC or EVC2 genes have been found to be the underlying cause. Methods In this paper, we describe the molecular (DNA sequencing and clinical analysis of six children diagnosed with EvC from four different families from the United Arab Emirates (UAE. Results All the children had the common clinical and radiological features of this syndrome. However, DNA sequence analysis of the genes shown to be involved (EVC and EVC2 revealed a novel splice site mutation (c.2047-1G>T in intron 13 of EVC2 gene in one family. In addition, we confirm previous mutational analyses that showed a truncating mutation in exon 13 of EVC gene (c.1813C>T; p.Q605X in the second family and a single nucleotide deletion (c.981delG; p.K327fs in exon 8 of EVC2 gene in the third family. No mutations in the exons, splice sites or the promoter regions of either gene have been found in the index case of the fourth family who exhibited "EvC-like" features. Conclusions Given the small population size of UAE, our data illustrates further the molecular heterogeneity observed in EvC patients and excludes the possibility of a common founder effect for this condition in the UAE reflecting the current ethnic diversity of the country.

  20. Novel mutations in EVC cause aberrant splicing in Ellis-van Creveld syndrome.

    Ellis-van Creveld syndrome (EvC) is a rare autosomal recessive disorder characterized by disproportionate chondrodysplasia, postaxial polydactyly, nail dystrophy, dental abnormalities and in a proportion of patients, congenital cardiac malformations. Weyers acrofacial dysostosis (Weyers) is another dominantly inherited disorder allelic to EvC syndrome but with milder phenotypes. Both disorders can result from loss-of-function mutations in either EVC or EVC2 gene, and phenotypes associated with the two gene mutations are clinically indistinguishable. We present here a clinical and molecular analysis of a Chinese family manifested specific features of EvC syndrome. Sequencing of both EVC and EVC2 identified two novel heterozygous splice site mutations c.384+5G>C in intron 3 and c.1465-1G>A in intron 10 in EVC, which were inherited from mother and father, respectively. In vitro minigene expression assay, RT-PCR and sequencing analysis demonstrated that c.384+5G>C mutation abolished normal splice site and created a new cryptic acceptor site within exon 4, whereas c.1465-1G>A mutation affected consensus splice junction site and resulted in full exon 11 skipping. These two aberrant pre-mRNA splicing processes both produced in-frame abnormal transcripts that possibly led to abolishment of important functional domains. To our knowledge, this is the first report of EVC mutations that cause EvC syndrome in Chinese population. Our data revealed that EVC splice site mutations altered splicing pattern and helped elucidate the pathogenesis of EvC syndrome.

    One of the hallmarks of cancer, global gene expression alteration, is closely associated with the development and malignant characteristics associated with adult T-cell leukemia (ATL) as well as other cancers. Here, we show that aberrant overexpression of the Ellis Van Creveld (EVC) family is responsible for cellular Hedgehog (HH) activation, which provides the pro-survival ability of ATL cells. Using microarray, quantitative RT-PCR and immunohistochemistry we have demonstrated that EVC is significantly upregulated in ATL and human T-cell leukemia virus type I (HTLV-1)-infected cells. Epigenetic marks, including histone H3 acetylation and Lys4 trimethylation, are specifically accumulated at the EVC locus in ATL samples. The HTLV-1 Tax participates in the coordination of EVC expression in an epigenetic fashion. The treatment of shRNA targeting EVC, as well as the transcription factors for HH signaling, diminishes the HH activation and leads to apoptotic death in ATL cell lines. We also showed that a HH signaling inhibitor, GANT61, induces strong apoptosis in the established ATL cell lines and patient-derived primary ATL cells. Therefore, our data indicate that HH activation is involved in the regulation of leukemic cell survival. The epigenetically deregulated EVC appears to play an important role for HH activation. The possible use of EVC as a specific cell marker and a novel drug target for HTLV-1-infected T-cells is implicated by these findings. The HH inhibitors are suggested as drug candidates for ATL therapy. Our findings also suggest chromatin rearrangement associated with active histone markers in ATL. © 2014 The Authors.

    Ellis-van Creveld (EvC) syndrome is an autosomal recessive chondrodysplastic condition with clinical manifestations that include short-limbs and ribs, postaxial polydactyly and dysplastic nails and teeth. In about two thirds of patients, mutations in either EVC or EVC2 genes have been found to be the underlying cause. In this paper, we describe the molecular (DNA sequencing) and clinical analysis of six children diagnosed with EvC from four different families from the United Arab Emirates (UAE). All the children had the common clinical and radiological features of this syndrome. However, DNA sequence analysis of the genes shown to be involved (EVC and EVC2) revealed a novel splice site mutation (c.2047-1G>T) in intron 13 of EVC2 gene in one family. In addition, we confirm previous mutational analyses that showed a truncating mutation in exon 13 of EVC gene (c.1813C>T; p.Q605X) in the second family and a single nucleotide deletion (c.981delG; p.K327fs) in exon 8 of EVC2 gene in the third family. No mutations in the exons, splice sites or the promoter regions of either gene have been found in the index case of the fourth family who exhibited "EvC-like" features. Given the small population size of UAE, our data illustrates further the molecular heterogeneity observed in EvC patients and excludes the possibility of a common founder effect for this condition in the UAE reflecting the current ethnic diversity of the country.

    To evaluate clinical outcome of patients with Ellis-van Creveld syndrome (EVC) in whom congenital heart disease (CHD) repair was delayed intentionally to reduce the risk of postoperative respiratory morbidity and mortality. This retrospective review of 51 EVC c.1886+5G>T homozygotes born between 2005 and 2014 focused on 18 subjects who underwent surgery for CHD, subdivided into early (mean, 1.3 months) vs delayed (mean, 50.1 months) repair. Growth trajectories differed between control subjects and patients with EVC, and CHD was associated with slower weight gain. Relative to controls, infants with EVC had a 40%-75% higher respiratory rates (independent of CHD) accompanied by signs of compensated respiratory acidosis. Blood gases and respiratory rates approached normal values by age 4 years. Hemodynamically significant CHD was present in 23 children, 18 (78%) of whom underwent surgical repair. Surgery was performed at 1.3 ± 1.3 months for children born between 2005 and 2009 (n = 9) and 50.1 ± 40.2 months (P = .009) for children born between 2010 and 2014 (n = 9). The latter had shorter postoperative mechanical ventilation (1.1 ± 2.4 days vs 49.6 ± 57.1 days; P = .075), shorter intensive care duration of stay (16 ± 24 days vs 48.6 ± 44.2 days; P = .155), and no postoperative tracheostomies (vs 60%; P = .028) or deaths (vs 44%; P = .082). Among children with EVC and possibly other short-rib thoracic dysplasias, delayed surgical repair of CHD reduces postoperative morbidity and improves survival. Respiratory rate serves as a simple indicator for optimal timing of surgical repair. Copyright © 2017 Elsevier Inc. All rights reserved.

    Ellis-van Creveld (EvC) syndrome is a genetic disorder with mutations in either EVC or EVC2 gene. Previous case studies reported that EvC patients underwent orthodontic treatment, suggesting the presence of craniofacial bone phenotypes. To investigate whether a mutation in EVC2 gene causes a craniofacial bone phenotype, Evc2 knockout (KO) mice were generated and cephalometric analysis was performed. The heads of wild type (WT), heterozygous (Het) and homozygous Evc2 KO mice (1-, 3-, and 6-week-old) were prepared and cephalometric analysis based on the selected reference points on lateral X-ray radiographs was performed. The linear and angular bone measurements were then calculated, compared between WT, Het and KO and statistically analyzed at each time point. Our data showed that length of craniofacial bones in KO was significantly lowered by ∼20% to that of WT and Het, the growth of certain bones, including nasal bone, palatal length, and premaxilla was more affected in KO, and the reduction in these bone length was more significantly enhanced at later postnatal time points (3 and 6 weeks) than early time point (1 week). Furthermore, bone-to-bone relationship to cranial base and cranial vault in KO was remarkably changed, i.e. cranial vault and nasal bone were depressed and premaxilla and mandible were developed in a more ventral direction. Our study was the first to show the cause-effect relationship between Evc2 deficiency and craniofacial defects in EvC syndrome, demonstrating that Evc2 is required for craniofacial bone development and its deficiency leads to specific facial bone growth defect.

    Ellis-van Creveld (EvC) syndrome is a human autosomal recessive disorder caused by a mutation in either the EVC or EVC2 gene, and presents with short limbs, polydactyly, and ectodermal and heart defects. The aim of this study was to understand the pathologic basis by which deletions in the EVC2 gene lead to chondrodysplastic dwarfism and to describe the morphologic, immunohistochemical, and molecular hallmarks of EvC syndrome in cattle. Five Grey Alpine calves, with a known mutation in the EVC2 gene, were autopsied. Immunohistochemistry was performed on bone using antibodies to collagen II, collagen X, sonic hedgehog, fibroblast growth factor 2, and Ki67. Reverse transcription polymerase chain reaction was performed to analyze EVC1 and EVC2 gene expression. Autopsy revealed long bones that were severely reduced in length, as well as genital and heart defects. Collagen II was detected in control calves in the resting, proliferative, and hypertrophic zones and in the primary and secondary spongiosa, with a loss of labeling in the resting zone of 2 dwarfs. Collagen X was expressed in hypertrophic zone in the controls but was absent in the EvC cases. In affected calves and controls, sonic hedgehog labeled hypertrophic chondrocytes and primary and secondary spongiosa similarly. FGF2 was expressed in chondrocytes of all growth plate zones in the control calves but was lost in most EvC cases. The Ki67 index was lower in cases compared with controls. EVC and EVC2 transcripts were detected. Our data suggest that EvC syndrome of Grey Alpine cattle is a disorder of chondrocyte differentiation, with accelerated differentiation and premature hypertrophy of chondrocytes, and could be a spontaneous model for the equivalent human disease. © The Author(s) 2015.

    Full Text Available CONTEXT: Ellis-van Creveld (EVC syndrome is a rare autosomal recessive disease characterized by disproportionate short stature, narrow thorax, postaxial polydactyly, nail and tooth abnormalities and congenital heart disease. CASE REPORT: The patient was a 22-year-old Caucasian man, the third child of consanguineous parents. He received the diagnosis of insulin-dependent diabetes mellitus (DM at 16 years of age, and around one year later, he underwent surgery to correct a partial atrioventricular septal defect. Upon physical examination, at 22 years of age, he presented stature of 145.5 cm (P3, weight of 49 kg (P3, head circumference of 54 cm (P2-50, high palate, absence of one of the lower lateral incisor teeth, narrow shoulders, narrowing of the upper thorax, scoliosis, rhizomelic shortening of the upper limbs, brachydactyly, postaxial polydactyly and clinodactyly of the second and third fingers. The lower limbs showed rhizomelic shortening with significant genu valgum (knock-knee deformity, small feet with postaxial polydactyly, syndactyly between the second and third toes and hallux valgus. Multiple melanocytic nevi were evident on the face, thorax and limbs. At that time, he was using neutral protamine Hagedorn (NPH insulin, with poorly controlled DM. The clinical findings presented led to the diagnosis of EVC syndrome. Only one case of this syndrome has been described with DM so far. Attention is drawn to the fact that the genes associated with this syndrome are located close to those of the Wolfram syndrome, a condition that leads to early-onset diabetes.

    Ellis-Van Creveld Syndrome or chondrectodermal dysplasia is produced by an autosomal recessive inheritance secondary to mutation in the short arm of chromosome 4. The syndrome affects multiple organs. It is described as a clinical tetrad that involves chondrodysplasia, ectodermal dysplasia, polydactyly and congenital heart defects. It is only known from reports and case series. We present a three months old male, without relevant family history, who presented chondrodysplasia, upper lip merged to palate, bilateral sinpolydactyly in the hands, developmental dysplasia of the hip, narrow chest with short ribs, and heart defects. This case is the first report of EVC in Peruvian literature.

    CMS computing needs reliable, stable and fast connections among multi-tiered computing infrastructures. CMS experiment relies on File Transfer Services (FTS) for data distribution, a low level data movement service responsible for moving sets of files from one site to another, while allowing participating sites to control the network resource usage. FTS servers are provided by Tier-0 and Tier-1 centers and used by all the computing sites in CMS, subject to established CMS and sites setup policies, including all the virtual organizations making use of the Grid resources at the site, and properly dimensioned to satisfy all the requirements for them. Managing the service efficiently needs good knowledge of the CMS needs for all kind of transfer routes, and the sharing and interference with other Virtual Organizations using the same FTS transfer managers. This contribution deals with a complete revision of all FTS servers used by CMS, customizing the topologies and improving their setup in order to keep CMS trans...

    2016-01-01

    During LHC Long Shutdown 1 necessary upgrades to the CMS detector were made. CMS also took the opportunity to improve further particle reconstruction. A number of improvements were made to the Hadronic Tau reconstruction and Identification algorithms. In particular, electromag- netic strip reconstruction of the Hadron plus Strips (HPS) algorithm was improved to better model signal of pi0 from tau decays. This modification improves energy response and removes the tau footprint from isolation area. In addition to this, improvement to discriminators combining iso- lation and tau life time variables, and anti-electron in MultiVariate Analysis technique was also developed. The results of these improvements are presented and validation of Tau Identification using a variety of techniques is shown.

    The tracking system of the CMS detector provides excellent resolution for charged particle tracks and an efficient way of tagging jets. In order to reconstruct good quality tracks, the position and orientation of each silicon pixel and strip module needs to be determined with a precision of several micrometers. The presented alignment results are derived following a global (Millepede-II) and a local (HipPy) fit approach. The performance of the CMS tracker alignment in 2016 using cosmic-ray data and the complete set of proton-proton collision data recorded at 3.8 T magnetic field has been studied. The data-driven validation of the results are shown. The time-dependent movement of the pixel detector's large-scale structure is demonstrated.

    Measurements of the top quark mass are presented, obtained from CMS data collected in proton-proton collisions at the LHC at centre-of-mass energies of 7 TeV and 8 TeV. The mass of the top quark is measured using several methods and channels, including the reconstructed invariant mass distribution of the top quark, an analysis of endpoint spectra as well as measurements from shapes of top quark decay distributions. The dependence of the mass measurement on the kinematic phase space is investigated. The results of the various channels are combined and compared to the world average. The top mass and also $\\alpha_{\\textnormal S}$ are extracted from the top pair cross section measured at CMS.

    The Front End Driver, FED, is a 9U 400mm VME64x card designed for reading out the Compact Muon Solenoid, CMS, silicon tracker signals transmitted by the APV25 analogue pipeline Application Specific Integrated Circuits. The FED receives the signals via 96 optical fibers at a total input rate of 3.4 GB/sec. The signals are digitized and processed by applying algorithms for pedestal and common mode noise subtraction. Algorithms that search for clusters of hits are used to further reduce the input rate. Only the cluster data along with trigger information of the event are transmitted to the CMS data acquisition system using the S-LINK64 protocol at a maximum rate of 400 MB/sec. All data processing algorithms on the FED are executed in large on-board Field Programmable Gate Arrays. Results on the design, performance, testing and quality control of the FED are presented and discussed.

    The Trigger Supervisor is an online software system designed for the CMS experiment at CERN. Its purpose is to provide a framework to set up, test, operate and monitor the trigger components on one hand and to manage their interplay and the information exchange with the run control part of the data acquisition system on the other. The Trigger Supervisor is conceived to provide a simple and homogeneous client interface to the online software infrastructure of the trigger subsystems. This document specifies the functional and non-functional requirements, design and operational details, and the components that will be delivered in order to facilitate a smooth integration of the trigger software in the context of CMS.

  16. Tracking at High Level Trigger in CMS

    2014-01-01

    A reduction of several orders of magnitude of the event rate is needed to reach values compatible with detector readout, offline storage and analysis capability. The CMS experiment has been designed with a two-level trigger system: the Level-1 Trigger (L1T), implemented on custom-designed electronics, and the High Level Trigger (HLT), a streamlined version of the CMS offline reconstruction software running on a computer farm. A software trigger system requires a trade-off between the complexity of the algorithms, the sustainable output rate, and the selection efficiency. With the computing power available during the 2012 data taking the maximum reconstruction time at HLT was about 200 ms per event, at the nominal L1T rate of 100 kHz. Track reconstruction algorithms are widely used in the HLT, for the reconstruction of the physics objects as well as in the identification of b-jets and lepton iso...

  17. Alignment procedures for the CMS silicon tracker

    CERN Document Server

    Behr, Joerg

    2012-01-01

    The CMS all-silicon tracker consists of 16588 modules. Therefore its alignment procedures require sophisticated algorithms. Advanced tools of computing, tracking and data analysis have been deployed for reaching the targeted performance. Ultimate local precision is now achieved by the determination of sensor curvatures, challenging the algorithms to determine about 200k parameters simultaneously. Systematic biases in the geometry are controlled by adding further information into the alignment workflow, e.g. the mass of decaying resonances. The orientation of the tracker with respect to the magnetic field of CMS is determined with a stand-alone chi-square minimization procedure. The geometries are finally carefully validated. The monitored quantities include the basic track quantities for tracks from both collisions and cosmic muons and physics observables.

    2008-01-01

    The CMS Tracker measures the momentum of charged particles created in proton-proton interactions with 14\\,TeV nominal center-of-mass energy close to the interaction region. Its excellent single-point position resolution of 9--60\\,$\\mu$m\\ is far below typical construction tolerances, and together with its high granularity renders the alignment a demanding task, which needs to aim at micro-meter level precision. A strategy to align the CMS tracker with its 15\\,148 silicon strip and 1\\,440 silicon pixel modules, starting from survey measurements during construction, incorporating information from the laser hardware monitoring system and finally using collision and non-collision tracks for highest precision has been developed and is detailed in this article.

    CRAB is a tool used for distributed analysis of CMS data. Users can submit sets of jobs with similar requirements (tasks) with a single request. CRAB uses a client-server architecture, where a lightweight client, a server, and ancillary services work together and are maintained by CMS operators at CERN. As with most complex software, good monitoring tools are crucial for efficient use and longterm maintainability. This work gives an overview of the monitoring tools developed to ensure the CRAB server and infrastructure are functional, help operators debug user problems, and minimize overhead and operating cost. This work also illustrates the design choices and gives a report on our experience with the tools we developed and the external ones we used.

    The data acquisition system (DAQ) of the CMS experiment at the CERN Large Hadron Collider (LHC) assembles events at a rate of 100 kHz. It transports event data at an aggregate throughput of ~100 GB/s to the high-level trigger (HLT) farm. The CMS DAQ system has been completely rebuilt during the first long shutdown of the LHC in 2013/14. The new DAQ architecture is based on state-of-the-art network technologies for the event building. For the data concentration, 10/40 Gb/s Ethernet technologies are used together with a reduced TCP/IP protocol implemented in FPGA for a reliable transport between custom electronics and commercial computing hardware. A 56 Gb/s Infiniband FDR CLOS network has been chosen for the event builder. We report on the performance of the event builder system and the steps taken to exploit the full potential of the network technologies.

  1. Muon Reconstruction and Identification in CMS

    International Nuclear Information System (INIS)

    Everett, A.

    2010-01-01

    We present the design strategies and status of the CMS muon reconstruction and identification identification software. Muon reconstruction and identification is accomplished through a variety of complementary algorithms. The CMS muon reconstruction software is based on a Kalman filter technique and reconstructs muons in the standalone muon system, using information from all three types of muon detectors, and links the resulting muon tracks with tracks reconstructed in the silicon tracker. In addition, a muon identification algorithm has been developed which tries to identify muons with high efficiency while maintaining a low probability of misidentification. The muon identification algorithm is complementary by design to the muon reconstruction algorithm that starts track reconstruction in the muon detectors. The identification algorithm accepts reconstructed tracks from the inner tracker and attempts to quantify the muon compatibility for each track using associated calorimeter and muon detector hit information. The performance status is based on detailed detector simulations as well as initial studies using cosmic muon data.

    The CMS data acquisition system comprises O(20000) interdependent services that need to be monitored in near real-time. The ability to monitor a large number of distributed applications accurately and effectively is of paramount importance for robust operations. Application monitoring entails the collection of a large number of simple and composed values made available by the software components and hardware devices. A key aspect is that detection of deviations from a specified behaviour is supported in a timely manner, which is a prerequisite in order to take corrective actions efficiently. Given the size and time constraints of the CMS data acquisition system, efficient application monitoring is an interesting research problem. We propose an approach that uses the emerging paradigm of Web-service based eventing systems in combination with hierarchical data collection and load balancing. Scalability and efficiency are achieved by a decentralized architecture, splitting up data collections into regions of col...

  3. Analysing CMS transfers using Machine Learning techniques

    CERN Document Server

    Diotalevi, Tommaso

    2016-01-01

    LHC experiments transfer more than 10 PB/week between all grid sites using the FTS transfer service. In particular, CMS manages almost 5 PB/week of FTS transfers with PhEDEx (Physics Experiment Data Export). FTS sends metrics about each transfer (e.g. transfer rate, duration, size) to a central HDFS storage at CERN. The work done during these three months, here as a Summer Student, involved the usage of ML techniques, using a CMS framework called DCAFPilot, to process this new data and generate predictions of transfer latencies on all links between Grid sites. This analysis will provide, as a future service, the necessary information in order to proactively identify and maybe fix latency issued transfer over the WLCG.

    1) Kostas Theofilatos will give an introduction to CMS result 2) Ben Allanach: Several CMS analyses involving di-leptons have recently reported small 2.4-2.8 sigma local excesses: nothing to get too excited about, but worth keeping an eye on nonetheless. In particular, a search in the $lljj p_T$(miss) channel, a search for $W_R$ in the $lljj$ channel and a di-leptoquark search in the $lljj$ channel and $ljj p_T$(miss) channel have all yielded small excesses. We interpret the first excess in the MSSM, showing that the interpretation is viable in terms of other constraints, despite only having squark masses of around 1 TeV. We can explain the last three excesses with a single R-parity violating coupling that predicts a non-zero contribution to the neutrinoless double beta decay rate.

    The web application service is part of the condition database system of the CMS experiment. The application server is built upon condition python API in the CMS offline software framework and serves applications and users not involved in the event-processing. The main client of the application server is the condition database web GUI, which currently exposes three main services: the Tag Browser, the Global Tag, the Historic Chart condition date in terms of their version (TAG) and the interval of validity (IOV). The global tag component is used by physicists to inspect the organization of the tags in a given data taking or data production, while production managers use the web service to produce such tag hierarchy. The History chart plotting service creates dynamic summary and distribution charts of the payload data in the database. Fast graphical overview of different information greatly contributes in monitoring and validating the calibration data stored in the condition database.

    The CMS experiment (Compact Muon Solenoid) is a general-purpose detector designed to run at the highest luminosity at the CERN Large Hadron Collider (LHC). Its distinctive features include a 4 T superconducting solenoid with a free bore of 6 m diameter and 12.5-m length, enclosed inside a 10 000-ton return yoke. The magnet will be assembled and tested in a surface hall at Point 5 of the LHC at the beginning of 2004 before being transferred by heavy lifting means to an experimental hall 90 m below ground level. The design and construction of the magnet is a common project of the CMS Collaboration. The task is organized by a CERN based group with strong technical and contractual participation from CEA Saclay, ETH Zurich, Fermilab, INFN Genova, ITEP Moscow, University of Wisconsin and CERN. The magnet project will be described, with emphasis on the present status of the fabrication. (15 refs).

This work gives an overview of the monitoring tools developed to ensure the CRAB server and infrastructure are functional, help operators debug user problems, and minimize overhead and operating cost. This work also illustrates the design choices and gives a report on our experience with the tools we developed and the external ones we used.

  8. CMS Developments for Track-Triggers

    2015-01-01

    The High Luminosity LHC (HL-LHC) is expected to deliver luminosities of 5$\\times10^{34}$cm$^{-2}$s$^{-1}$, with an average of about 140 overlapping proton-proton collisions per bunch crossing. These extreme pileup conditions place stringent requirements on the trigger system to be able to cope with the resulting event rates. A key component of the CMS upgrade for HL-LHC is a track trigger system which would identify tracks with transverse momentum above 2~\\,GeV already at the first-level trigger (L1). We present the status of proposals for implementing the L1 tracking in conjunction with the planned upgrade for the silicon tracker of the CMS experiment. The expected performance and the use of L1 tracks for triggering is discussed.

    The work described in this paper is a novel design of a robotic Venus flytrap (VFT) (Dionaea muscipula Ellis) by means of ionic polymeric metal composite (IPMC) artificial muscles as distributed nanosensors and nanoactuators. Rapid muscular movements in carnivorous plants, such as VFT, which are triggered by antenna-like sensors (trigger hair), present a golden key to study distributed biomolecular motors. Carnivorous plants, such as VFT, possess built-in intelligence (trigger hairs), as a strategy to capture prey, that can be turned on in a controlled manner. In the case of the VFT, the prey that is lured by the sweet nectar in the VFT pair of jaw-like lobes has to flip and move the trigger hairs, which are colorless, bristle-like and pointed. The dynamically moved trigger hairs then electro-elastically send an electric signal to the internal ions in the lobe to migrate outwardly for the jaw-like lobes to close rapidly to capture the prey. The manner in which the VFT lobes bend inward to capture the prey shows a remarkable similarity with typical IPMCs bending in an electric field. Furthermore, the mechano-electrical sensing characteristics of IPMCs also show a remarkable resemblance to mechano-electrical trigger hairs on the lobes of the VFT. The reader is referred to a number of papers in connection with sensing and actuation of IPMCs in particular. Thus, one can integrate IPMC lobes with a common electrode in the middle of one end of the lobes to act like a spine and use IPMC bristles as trigger finger to sense the intrusion of a fly or insect to send a sensing signal to a solid state relay which then triggers the actuation circuit of the IPMC lobes to rapidly bend toward each other and close. The two lobes, which form the trap, are attached to the midrib common electrode which is conveniently termed the spine. The upper surface of each lobe is dished, and spaced along the free margins of the lobes with some 15-20 prong-like teeth. These are tough and pointed

    To present the perinatal findings and molecular genetic analysis of two siblings with Ellis-van Creveld (EvC) syndrome. A 33-year-old woman, gravida 3, para 1, was referred for genetic counseling at 18 gestational weeks because of recurrent fetal skeletal dysplasia. Two years previously, she had delivered a 1,316-g dead male baby at 28 gestational weeks with a karyotype of 46,XY, postaxial polydactyly of the hands, thoracic narrowness, endocardial cushion defects, transposition of the great arteries, shortening of the long bones, malposition of the toes, and hypoplastic nails. During this pregnancy, prenatal ultrasound at 18 gestational weeks revealed shortening of the long bones (equivalent to 15 weeks), postaxial polydactyly of both hands, thoracic narrowness, and endocardial cushion defects. The pregnancy was subsequently terminated, and a 236-g female fetus was delivered with a karyotype of 46,XX, postaxial polydactyly of the hands, thoracic dysplasia, endocardial cushion defects, shortening of the long bones, and malposition of the toes and hypoplastic nails. The phenotype of each of the two siblings was consistent with EVC syndrome. Molecular analysis of the EVC and EVC2 genes revealed heterozygous mutations in the EVC2 gene. A heterozygous deletion mutation of a 26-bp deletion of c.871-2_894del26 encompassing the junction between intron 7 and exon 8 of the EVC2 gene was found in the mother and two siblings, and a heterozygous nonsense mutation of c.1195C >T, p.R399X in exon 10 of the EVC2 gene was found in the father and two siblings. Prenatal sonographic identification of endocardial cushion defects in association with shortening of the long bones should alert clinicians to the possibility of EvC syndrome and prompt a careful search of hexadactyly of the hands. Molecular analysis of the EVC and EVC2 genes is helpful in genetic counseling in cases with prenatally detected postaxial polydactyly, thoracic narrowness, short limbs and endocardial cushion defects

    Top quarks are produced copiously at the LHC, and a variety of related measurements has been made in the recent years by the two collaborations ATLAS and CMS. The most recent measurements of the top quark mass by the two collaborations are reported here. The top quark mass has been measured with a relative uncertainty smaller than 0.3pct, making the top quark the most accurately measured quark.

    The top quark is the heaviest known elementary particle. It decays almost exclusively into a W boson and a b quark. The latest results on the Wtb vertex together with measurements of other properties of the top quark in ATLAS and CMS are presented in this talk. Furthermore, the talk shows results on the associated production of tt with a Z or W boson, which provides a direct measurement of the top quark coupling to the Z or W boson.

    The pictures show a cross section of the CMS solenoid. One can see four layers of the superconducting coil, each of which contains the superconductor (central part, copper coloured - niobium-titanium strands in a copper coating, made into a "Rutherford cable"), surrounded by an ultra-pure aluminium as a magnetic stabilizer, then an aluminium alloy as a mechanical stabilizer. Besides the four layers there is an aluminium mechanical piece that includes pipes that transport the liquid helium.

    Every second the Earth is bombarded by billions of cosmic rays and occasionally one of these cosmic particles will collide with the Earth's atmosphere generating a shower of particles known as an 'air shower'. This is similiar to the collisions and subsequent particle showers observed in accelerators such as the LHC. Here the CMS detector is closed so that systems can be tested using muon cosmic rays in the 'Cosmic Challenge'.

    The CMS tracker is the largest silicon detector ever built, covering 200 square meters and providing an average of 14 high-precision measurements per track. The use of tracker data for reconstruction of charged particles and primary and secondary vertices requires fine-grained monitoring and calibration procedures as well as accurate alignment. Results from timing and threshold optimization, gain calibration, and Lorentz angle determination are shown and the impact on resolution and dE/dx measurements is discussed.

    The soft and hard QCD processes are analyzed by the ATLAS and CMS experiments using samples of proton-proton collisions collected by the LHC at sqrt{s}=7 and 8 TeV. Measurements of jet production rates, jet properties, particle multiplicity and particle momentum spectra are presented. The results are compared to predictions of theoretical models at leading- and next-to-leading orders of QCD. The data are used to measure the strong coupling constant and for PDF constraints.
