  1. Mathematical methods for B0 anti B0 oscillation analyses

    1996-01-01

    The measurement of the B 0 s anti B 0 s mixing frequency Δm s requires the search for a periodic pattern in the time distribution of the data. Using Fourier analysis the consequences of vertex and boost resolution, mistag and statistical fluctuations are treated analytically and a general expression to estimate the significance of a B 0 anti B 0 mixing analysis is derived. With the help of Fourier analysis the behaviour of a classical maximum likelihood analysis in time space is studied, too. It can be shown that a naive maximum likelihood fit fails in general to give correct confidence levels. This is especially important if limits are calculated. Alternative methods, based on the likelihood, which give correct limits are discussed. A new method, the amplitude fit, is introduced which combines the advantages of a Fourier analysis with the power and simplicity of a maximum likelihood fit. (orig.)

    Several monoclonal antibodies targeting B cells have been tested as therapeutics for inflammatory rheumatic diseases. We review important observations from randomized clinical trials regarding the efficacy and safety of anti-B cell antibody-based therapies for rheumatoid arthritis, systemic lupus...... and functions in rheumatic disorders. Future studies should also evaluate how to maintain disease control by means of conventional and/or biologic immunosuppressants after remission-induction with anti-B cell antibodies....

    Using the ARGUS detector at the DORIS II storage ring we have searched in three different ways for B 0 -anti B 0 mixing in Υ (4S) decays. One explicitly mixed event, a decay Υ (4S) → B 0 B 0 , has been completely reconstructed. Furthermore, we observe a 4.0 standard deviation signal of 24.8 events with like-sign lepton pairs and a 3.0 standard deviation signal of 4.1 events containing one reconstructed B 0 (anti B 0 ) and an additional fast l + (l - ). This leads to the conclusion that B 0 -anti B 0 mixing is substantial. For the mixing parameter we obtain r = 0.21±0.08. (orig.)

  8. Bioscience, bioinnovations, and bioethics.

    Science.gov (United States)

    Leisola, Matti

    2007-01-01

    Biosciences and their applications, which we call biotechnology, have affected human society in many ways. Great hopes have been set on future biotechnology. The future depends on three key issues. First, we need good science. Recent developments in biosciences have surprised us in many ways. I shall explain in this article how. Secondly, we need structured innovation systems in order to commercialize our discoveries. Europe is slow in this respect compared to our Japanese and American competitors and may lose in the competition. I shall describe the Finnish innovation chain using the rewarded Otaniemi model as an example of how commercialization can be done in a systematic way. Thirdly, we need norms to guide what to do and where to go. Bioethics is probably the most neglected of the three key issues. With modern biotechnology we are able to do things that should worry every citizen, but the ethical discussion has been largely neglected or the discussion in our pluralistic society is leading nowhere. I shall finally discuss these problems from a historical perspective.

  9. Has bioscience reconciled mind and body?

    Science.gov (United States)

    Davies, Carmel; Redmond, Catherine; Toole, Sinead O; Coughlan, Barbara

    2016-09-01

    The aim of this discursive paper is to explore the question 'has biological science reconciled mind and body?'. This paper has been inspired by the recognition that bioscience has a historical reputation for privileging the body over the mind. The disregard for the mind (emotions and behaviour) cast bioscience within a 'mind-body problem' paradigm. It has also led to inherent limitations in its capacity to contribute to understanding the complex nature of health. This is a discursive paper. Literature from the history and sociology of science and psychoneuroimmunology (1975-2015) inform the arguments in this paper. The historical and sociological literature provides the basis for a socio-cultural debate on mind-body considerations in science since the 1970s. The psychoneuroimmunology literature draws on mind-body bioscientific theory as a way to demonstrate how science is reconciling mind and body and advancing its understanding of the interconnections between emotions, behaviour and health. Using sociological and biological evidence, this paper demonstrates how bioscience is embracing and advancing its understanding of mind-body interconnectedness. It does this by demonstrating the emotional and behavioural alterations that are caused by two common phenomena; prolonged, chronic peripheral inflammation and prolonged psychological stress. The evidence and arguments provided has global currency that advances understanding of the inter-relationship between emotions, behaviour and health. This paper shows how bioscience has reconciled mind and body. In doing so, it has advanced an understanding of science's contribution to the inter-relationship between emotions, behaviour and health. The biological evidence supporting mind-body science has relevance to clinical practice for nurses and other healthcare professions. This paper discusses how this evidence can inform and enhance clinical practice directly and through research, education and policy. © 2015 John Wiley

  10. Anti-B-B Mixing Constrains Topcolor-Assisted Technicolor

    International Nuclear Information System (INIS)

    Burdman, Gustavo; Lane, Kenneth; Rador, Tonguc

    2000-01-01

    We argue that extended technicolor augmented with topcolor requires that all mixing between the third and the first two quark generations resides in the mixing matrix of left-handed down quarks. Then, the anti-B d -B d mixing that occurs in topcolor models constrains the coloron and Z(prime) boson masses to be greater than about 5 TeV. This implies fine tuning of the topcolor couplings to better than 1 percent

  14. Environmental Biosciences Quarterly Report

    Energy Technology Data Exchange (ETDEWEB)

    Lawrence C. Mohr, M.D.

    2007-01-31

    In May 2002, the United States Department of Energy (DOE) signed Assistance Instrument Number DE-FC09-02CH11109 with the Medical University of South Carolina (MUSC) to support the Environmental Biosciences Program (EBP). This funding instrument replaces DOE Assistance Instrument Number DE-FC02-98CH10902. EBP is an integrated, multidisciplinary scientific research program, employing a range of research initiatives to identify, study and resolve environmental health risks. These initiatives are consistent with the MUSC role as a comprehensive state-supported health sciences institution and with the nation's need for new and better approaches to the solution of a complex and expansive array of environment-related health problems. The intrinsic capabilities of a comprehensive health sciences institution enable MUSC to be a national resource for the scientific investigation of environmental health issues. EBPs success as a nationally prominent research program is due, in part, to its ability to task-organize scientific expertise from multiple disciplines in addressing these complex problems. Current research projects have focused EBP talent and resources on providing the scientific basis for risk-based standards, risk-based decision making and the accelerated clean-up of widespread environmental hazards. These hazards include trichloroethylene and low-dose ionizing radiation. Work on the trichloroethylene research projects has been slowed as a result of funding uncertainties. The impact of these funding uncertainties has been discussed with the DOE. Plans for restructuring the performance schedule of the trichloroethylene projects have been submitted to the department. A project is also being conducted in the use of geographical information system technology to analyze population health risks related to environmental hazards as a tool for risk-based decision-making.

    We study the anti B{sub s}{sup 0} → J/ψK{sup +}K{sup -}, anti B{sup 0} → J/ψK{sup +}K{sup -}, B{sup -} → J/ψK{sup 0}K{sup -}, anti B{sup 0} → J/ψπ{sup 0}η and B{sup -} → J/ψπ{sup -}η decays and compare their mass distributions with those obtained for the anti B{sub s}{sup 0} → J/ψπ{sup +}π{sup -} and anti B{sup 0} → J/ψπ{sup +}π{sup -}. The approach followed consist in a factorization of the weak part and the hadronization part into a factor which is common to all the processes. Then what makes the reactions different are some trivial Cabibbo-Kobayashi-Maskawa matrix elements and the weight by which the different pairs of mesons appear in a primary step plus their final state interaction. These elements are part of the theory and thus, up to a global normalization factor, all the invariant mass distributions are predicted with no free parameters. Comparison is made with the limited experimental information available. Further comparison of these results with coming LHCb measurements will be very valuable to make progress in our understanding of the meson.meson interaction and the nature of the low lying scalar meson resonances, f{sub 0}(500), f{sub 0}(980) and a{sub 0}(980).

  16. Impact of leptonic tau decays on the distribution of anti B → Dμ anti ν

    We present results for the decay rate of anti B → Dτ(→ μ anti νν) anti ν, which is a sizeable background to anti B → Dμ anti ν decays. In particular, we calculate analytically the differential decay rate with respect to all seven kinematic variables. We consider the impact of this decay on the distributions of anti B → Dμ anti ν in either the muon helicity angle or the muon energy in the anti B rest frame. Our numerical results are obtained from Monte Carlo pseudo events. Finally, we provide necessary information for cross checks of the experimental analyses.

    Using the formulas for the dΓ/dq 2 distribution with non-zero lepton mass and experimentally determined form factors, we calculate the dΓ(D (*)+ l - anti ν)/dq 2 spectra and branching fractions for l=e,μ and τ. We obtain the results B(anti B 0 →D + τ - anti ν)/B(anti B 0 →D + e - anti ν)=0.278 +0.049 -0.035 and B(anti B 0 →D *+ τ - anti ν)/B(anti B 0 →D *+ e - anti ν)=0.256 +0.014 -0.013 . Since we used the experimentally measured form factors, these results are independent of theoretical models of the form factors. (orig.)

  8. Matrix elements for the anti B{yields}X{sub s}{gamma} decay at NNLO

    Energy Technology Data Exchange (ETDEWEB)

    Schutzmeier, Thomas Paul

    2009-12-17

    In the context of the indirect search for non-standard physics in the flavour sector of the Standard Model (SM), one of the most interesting processes is the rare inclusive anti B{yields} X{sub s}{gamma} decay. On the one hand, being a flavour-changing neutral current, this B decay is sensitive to new physics, as it is loop-suppressed in the SM. On the other hand, it is only mildly affected by non-perturbative effects, and thus allows for precise theoretical predictions in the framework of renormalization-group improved perturbation theory. Accurate measurements as well as precise theoretical predictions with a good control over both perturbative and non-perturbative contributions have to be provided in order to derive stringent constraints on the parameter space of physics beyond the SM. On the experimental side, an outstanding accuracy in the measurement of the anti B{yields}X{sub s}{gamma} decay rate has been achieved, which is mainly due the specialized experiments BaBar and Belle at the so-called B factories. To match the small experimental uncertainty, higher order computations within an effective low-energy theory of the SM are mandatory. In fact, next-to-next-to-leading order (NNLO) QCD corrections are required to provide a prediction for the decay rate with the same precision as the measurement. The NNLO evaluation of the anti B{yields}X{sub s}{gamma} decay rate has been pursued by various groups over the last decade. The project was completed to a large extent and a first estimate at this level of perturbation theory was obtained in 2006. This prediction, however, lacks important contributions from yet unknown matrix elements, that were estimated from results which are only partially known to date. In this work, we provide a framework for the systematic study of the missing matrix elements at the NNLO. As main results of this thesis, we determine fermionic corrections to the charm quark mass dependent matrix elements of four-quark operators in the

  10. Use of radiolabeled monoclonal anti-B1 antibody for B lymphocyte imaging in Rhesus monkeys

    International Nuclear Information System (INIS)

    Letvin, N.L.; Zalutsky, M.R.; Chalifoux, L.V.; Atkins, H.L.

    1987-01-01

    Imaging tissues rich in B lymphocytes in man using a radiolabeled monoclonal anti-B cell antibody would be extremely useful in the clinical staging of non-Hodgkins lymphomas. Studies were done in rhesus monkeys using radiolabeled monoclonal anti-B1 antibody to determine the feasibility of such an approach. Immunohistologic studies demonstrated that infused monoclonal anti-B1 binds in vivo with specificity to B cells in lymph nodes and spleen. The kinetics of clearance of 131 I-labeled anti-B1 were determined. The B lymphocyte-rich spleen could be readily visualized by gamma camera scanning without significant background and without the need for image intensification or blood background subtraction techniques. These data support the feasibility of using anti-B1 for staging B cell lymphomas in man. (author)

  11. Decay rate ratios of Υ(5S)→B anti B reactions

    We calculate the decay rate ratios for OZI allowed decays of Υ(5S) to two B mesons by using the decay amplitudes which incorporate the wave function of the Υ(5S) state. We obtain the result that the branching ratio of the Υ(5S) decay to B s * anti B s * is much larger than the branching ratio to B s anti B s * or anti B s B s * , in good agreement with the recent experimental results of CLEO and BELLE. This agreement with the experimental results is made possible since the nodes of the Υ(5S) radial wave function induce the nodes of the decay amplitude. We find that the results for the Υ(5S) decays to B u (*) anti B u (*) or B d (*) anti B d (*) pairs are sensitive to the parameter values used for the potential between heavy quarks. (orig.)

    We report on measurements of correlated b anti b production in p anti p at √s=630 GeV, using dimuon data to tag both the b and anti b quarks. Starting from an inclusive dimuon sample we obtain improved cross-sections for single inclusive beauty production and confirm our earlier results on B 0 - anti B 0 mixing. From a study of b anti b correlations we derive explicit cross-sections for semi-differential b anti b production. We compare the measured cross-sections and correlations to OMIKRON (α s 3 ) QCD predictions and find good quantitative agreement. From the measured angular distributions we establish a sizeable contribution from higher order QCD processes with a significance of about seven standard deviations. A large nonperturbative contribution to these higher order corrections is excluded. (orig.)

  13. On the possibility to detect the Higgs decay H → b anti b in the associated Z + b anti b production at the LHC

    Lipatov, A.V.; Zotov, N.P.

    2015-01-01

    We investigate the possibility to detect the scalar Higgs boson decay H → b anti b in the associated Z and b anti b production at the LHC using the k T -factorization QCD approach. Our consideration is based on the off-shell (i.e. depending on the transverse momenta of initial quarks and gluons) production amplitudes of q* anti q* → ZH → Zq' anti q', q* anti q* → Zq' anti q', and g*g* → Zq' anti q' partonic subprocesses supplemented with the Catani.Ciafoloni.Fiorani. Marchesini (CCFM) dynamics of parton densities in a proton. We argue that the H → b anti b signal could be observed at large transverse momenta near the Higgs boson peak despite the overwhelming QCD background, and we point out the important role of angular correlations between the produced Z boson and b-quarks.

    This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). NMR plays critical roles in bioscience and biotechnology in both imaging and structure determination. NMR is limited, however, by the inherent low sensitivity of the NMR experiment and the demands for spectral resolution required to study biomolecules. The authors addressed both of these issues by working on the development of NMR force microscopy for molecular imaging, and high field NMR with isotope labeling to overcome limitations in the size of biomolecules that can be studied using NMR. A novel rf coil design for NMR force microscopy was developed that increases the limits of sensitivity in magnetic resonance detection for imaging, and the authors demonstrated sub-surface spatial imaging capabilities. The authors also made advances in the miniaturization of two critical NMR force microscope components. They completed high field NMR and isotope labeling studies of a muscle protein complex which is responsible for regulating muscle contraction and is too large for study using conventional NMR approaches.

  11. What is provided and what the registered nurse needs--bioscience learning through the pre-registration curriculum.

    Science.gov (United States)

    Davis, Geraldine M

    2010-11-01

    Registered nurses undertaking programmes of study to become non-medical prescribers appear to have limited biological science knowledge. A case study was undertaken to determine whether the nurses entering Prescriber programmes considered studies in bioscience in their pre-registration nursing courses had been sufficient, linked to practice, and had prepared them for their roles as registered nurses. The literature identifies a continuing trend amongst nursing students describing a lack of sufficient bioscience in initial nurse education; there is limited literature on the views of experienced registered nurses. The participants in this study were 42 registered nurses from adult and mental health nursing, community and inpatient services. The results obtained from questionnaires and interviews are described. Questionnaire analysis identified that 57.1% of participants indicated bioscience in their pre-registration nursing programme had been limited and 40.5% stated the bioscience content had not prepared them for their roles on registration. Those reporting extensive coverage of bioscience were all aged over 41 years and had qualified before 1995. Greatest coverage of bioscience in pre-registration programmes was reported in relation to anatomy and physiology, with relatively limited coverage of microbiology, pharmacology or biochemistry. Respondents considered all five topics to be important. Interviews supported the questionnaire findings. Copyright © 2010 Elsevier Ltd. All rights reserved.

  15. A study of B0- anti B0 mixing using the ARGUS Detector

    International Nuclear Information System (INIS)

    Tzamariudaki, E.

    1995-02-01

    Using the ARGUS detector at the e + e - storage ring DORIS II at DESY, a study of the decay anti B 0 →D *+ l - anti νhas been performed by exploiting a partial D *+ reconstruction technique. The branching ratio was determined to be (4.4±0.3±0.3)% for this mode, and for the higher excited D * (J) states Br( anti B 0 →D (J) *+ l - anti ν)=(2.5±0.6±0.5)%. Furthermore, the inclusive D *+ branching ratio in B decays was measured by fully reconstructing D *+ candidates. Using a tagged subset of this sample of B 0 meson decays in the mode anti B 0 →D *+ l - anti ν, B d 0 anti B d 0 oscillations have been studied. For this purpose two tagging techniques have been applied: the standard method of using fast leptons, and a new technique which makes use of kaons to tag the b flavour content. Combining the values obtained by these two methods, the B 0 anti B 0 mixing parameter χ d , used to denote the strength of the oscillations, was determined to be χ d =0.165±0.057. In addition, using fully reconstructed D *+ candidates, a third study of the B 0 anti B 0 mixing parameter was carried out by investigating D *+ K ± correlations. The mixing measurements obtained using kaons to tag the B meson flavour employ this technique for the first time. Future CP violation measurements at B Factories will place critical reliance on this method. Finally, using the extracted value for the mixing parameter χ d , the CKM matrix element V td was determined and the B s 0 anti B s 0 mixing parameter χ s was obtained. (orig.)

    1993-01-01

    Exclusive semileptonic B decays with a D *+ meson in the final state have been studied using the ARGUS detector at the DORIS II storage ring. The branching ratio for the decay anti B 0 →D *+ l - anti ν, where l - is either e - or μ - , has been measured to be (5.2±0.5±0.6)%. A significant rate for the decay anti B→D ** l - anti ν has been observed. From an angular analysis of the cascade anti B 0 →D *+ (→D 0 π + )l - anti ν the forward-backward asymmetry A FB and the D *+ polarization parameter α have been determined to be A FB =0.20±0.08±0.06 and α=1.1±0.4±0.2.

    B- anti B-Mixing is parameterized by the matrix elements of local operators O{sub i}. For the computation of these matrix elements a bag factor B{sub i} can be introduced left angle anti B vertical stroke O{sub i} vertical stroke B right angle =B{sub i} left angle anti B vertical stroke O{sub i} vertical stroke B right angle {sup fac}, which is unity in naive factorization. Any deviation from unity describes the accuracy of the naive factorization prescription. Corrections to B{sub i} emerge from QCD radiative corrections and from nonperturbative contributions at order 1/m{sub b}. We present the current status of these corrections to B{sub i}.

    2017-01-01

    The possible neutral D (*) anti D (*) and B (*) anti B (*) molecular states are studied in the framework of the constituent quark models, which is extended by including the s-channel one-gluon exchange. Using different types of quark-quark potentials, we solve the four-body Schroedinger equation by means of the Gaussian expansion method. The bound states of D (*) anti D (*) with J PC = 1 ++ , 2 ++ and B (*) anti B (*) with J PC = 0 ++ , 1 +- , 1 ++ , 2 ++ are obtained. The molecular states D* anti D with J PC = 1 ++ and B* anti B with J PC = 1 +- are good candidates for X(3872) and Z 0 b (10610), respectively. The dependence of the results on the model parameters is also discussed. (orig.)

This funding instrument replaces DOE Assistance Instrument Number DE-FC02-98CH10902. EBP is an integrated, multidisciplinary scientific research program, employing a range of research initiatives to identify, study and resolve environmental health risks. These initiatives are consistent with the MUSC role as a comprehensive state-supported health sciences institution and with the nation's need for new and better approaches to the solution of a complex and expansive array of environment-related health problems. The intrinsic capabilities of a comprehensive health sciences institution enable MUSC to be a national resource for the scientific investigation of environmental health issues. EBPs success as a nationally prominent research program is due, in part, to its ability to task-organize scientific expertise from multiple disciplines in addressing these complex problems Current research projects have focused EBP talent and resources on providing the scientific basis for risk-based standards, risk-based decision making and the accelerated clean-up of widespread environmental hazards. These hazards include trichloroethylene and low-dose ionizing radiation. Work on the trichloroethylene research projects has been slowed as a result of funding uncertainties. The impact of these funding uncertainties has been discussed with the DOE. Plans for restructuring the performance schedule of the trichloroethylene projects have been submitted to the department. A project is also being conducted in the use of geographical information system technology to analyze population health risks related to environmental hazards as a tool for risk-based decision-making.

    2018-06-09

    Undergraduate nursing programs typically include students with limited 'on-campus' time who need learning resources that are flexible, technologically appropriate, remotely-accessible (mobile smart devices), and above all, engaging. This has presented academics with challenges surrounding institutional security firewalls, password-access requirements, intellectual property/ownership and staff/student privacy. To overcome these challenges a collection of evidence-based YouTube videos, posted on the Biological Sciences YouTube Channel, supported by the Biosciences in Nurse Education, and underpinned by Benner's pedagogical framework, were developed with the intention of moving students from novice to competent clinical bioscience users. The videos are highly successful; with over 310,000 views, 1.5 million minutes of viewing and more than 5000 subscribers since its inception (YouTube videos was enhanced by their familiarity with the presenter and the breadth of information available in small portions, creating a solid basis for the development of bioscience-competent nursing graduates. Moreover, these open source videos provide a free resource for continual revision and professional development informed by an international minimum bioscience standard for nurses post registration.

    Current research projects have focused Environmental Biosciences Program (EBP) talent and resources on providing the scientific basis for risk-based standards, risk-based decision making and the accelerated clean-up of widespread environmental hazards. These hazards include trichloroethylene, low-dose ionizing radiation (gamma and neutron) and alpha radiation from plutonium. Trichloroethylene research has been conducted as a joint collaborative effort with the University of Georgia. Work on the trichloroethylene research projects has been slowed as a result of funding uncertainties. The impact of these funding uncertainties has been discussed with the United States Department of Energy (DOE). Laboratory work has been completed on several trichloroethylene risk assessment projects, and these projects have been brought to a close. Plans for restructuring the performance schedule of the remaining trichloroethylene projects have been submitted to the department. A comprehensive manuscript on the scientific basis of trichloroethylene risk assessment is in preparation. Work on the low-dose radiation risk assessment projects is also progressing at a slowed rate as a result of funding uncertainties. It has been necessary to restructure the proponency and performance schedule of these projects, with the project on Low-Dose Radiation: Epidemiology Risk Models transferred to DOE Office of Science proponency under a separate funding instrument. Research on this project will continue under the provisions of the DOE Office of Science funding instrument, with progress reported in accordance with the requirements of that funding instrument. Progress on that project will no longer be reported in quarterly reports for DE-FC09-02CH11109. Following a meeting at the Savannah River Site on May 8, 2008, a plan was submitted for development of an epidemiological cohort study and prospective medical surveillance system for the assessment of disease rates among workers at the Savannah River

  12. J/ψ→γB anti B decays and the quark-pair creation model

    International Nuclear Information System (INIS)

    Ping Ronggang; Jiang Huanqing; Shen Pengnian; Zou Bingsong

    2002-01-01

    The authors generalize the quark-pair creation model to a study of the radiative decays J/ψ→γB anti B by assuming that the u, d or s quark pairs are created with the same interaction strength. From the calculation of the ratio of the decay widths Γ(J/ψ→γp anti B)/Γ(J/ψ→p anti p), the authors extract the quark-pair creation strength gI=15.40 GeV. Based on the SU(6) spin-flavour basis and the 'uds' basis, the radiative decay branching ratios containing strange baryons are evaluated. Measurements for these decay widths from the BESII data are suggested

  13. B0-anti B0 mixings and rare B-decays

    Ali, A.

    1992-11-01

    I present an update on the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements taking into account the current experimental and theoretical information on weak decays. The resulting fit is combined with the measured value of the B 0 d -anti B 0 d mixing ratio x d and estimates of the pseudoscalar coupling constants to determine the allowed range of the B 0 s -anti B 0 s mixing ration x s in the Standard Model (SM). For the central values of the parameters used we find 8 ≤ x s ≤ 24. Flavour changing neutral current (FCNC) B-decays are briefly reviewed; in particular the role of such decays in determining the CKM matrix elements V td and V ts is emphasized on the example of radiative B-decays, B → (X d + γ) and B → (X s + γ).

    The development of software systems for the biosciences is always closely connected to experimental practice. Programs must be able to handle the inherent complexity and heterogeneous structure of biological systems in combination with the measuring equipment. Moreover, a high degree of flexibility is required to treat rapidly changing experimental conditions. Object-oriented methodology seems to be well suited for this purpose. It enables an evolutionary approach to software development that still maintains a high degree of modularity. This paper presents experience with object-oriented technology gathered during several years of programming in the fields of bioprocess development and metabolic engineering. It concentrates on the aspects of experimental support, data analysis, interaction and visualization. Several examples are presented and discussed in the general context of the experimental cycle of knowledge acquisition, thus pointing out the benefits and problems of object-oriented technology in the specific application field of the biosciences. Finally, some strategies for future development are described.

  18. Inclusive b and b anti b production with quasi-multi-Regge kinematics at the Tevatron

    We consider b-jet hadroproduction in the quasi-multi-Regge-kinematics approach based on the hypothesis of gluon and quark Reggeization in t-channel exchanges at high energies. The preliminary data on inclusive b-jet and b anti b-dijet production taken by the CDF Collaboration at the Fermilab Tevatron are well described without adjusting parameters. We find the main contribution to inclusive b-jet production to be the scattering of a Reggeized gluon and a Reggeized b-quark to a b quark, which is described by the effective Reggeon-Reggeon-quark vertex. The main contribution to b anti b-pair production arises from the scattering of two Reggeized gluons to a b anti b pair, which is described by the effective Reggeon-Reggeon-quark-quark vertex. Our analysis is based on the Kimber-Martin-Ryskin prescription for unintegrated gluon and quark distribution functions using as input the Martin-Roberts-Stirling-Thorne collinear parton distribution functions of the proton.

    The most likely decay channel of the standard model Higgs boson is the decay into a b- and an anti-b-quark. The properties of b-jets formed by the hadronization of b-quarks are essential input variables to all ATLAS h → b anti b analyses. In boosted topologies the performance of standard b-tagging algorithms is diminished due to the merging of close - by jets. The aim of the study presented is the optimization of a b-tagging algorithm for boosted h → b anti b decays using track jets with a smaller than standard cone radius. The study is based on simulated events containing boosted Higgs bosons from the decay of a new heavy gauge boson W{sup '} → Wh. A motivation for the use of track jets for b-tagging is the fact that the reconstructed jet axis for track jets more closely describes the b-hadron flight direction than for calorimeter jets. Using jets with a smaller cone radius allows to resolve topologies where larger radius jets are already merged.

    Scientists founded the Life Sciences Research Foundation (LSRF) in 1983 as a non-profit pass through foundation that awards post doctoral fellowships in all areas of the life sciences. LSRF scientists review hundreds of applications each year from PhDs seeking support. For example this year, our 26th, we received 800 applications and our peer review committee will choose about 50 finalists who are eligible for these awards. We have no endowment so we solicit sponsors each year. The fellowships are sponsored by research oriented companies, foundations, philanthropists, the Howard Hughes Medical Institute, and other organizations who believe in the value of awarding fellowships to the best and the brightest young scientists. Our web site has a complete listing of all details about LSRF (http://www.lsrf.org/). In the late 1980s the Division of Bioscience in the Office of Basic Energy Science, a granting agency of the Department of Energy, joined this partnership. Bioscience's mandate was to support non-medical microbiology and plant sciences. LSRF received a series of 5 year grants from DOE to award fellowships to our top applicants in these fields of research. We began to support DOE-Energy Bioscience post doctoral fellows in 1989. From 1989 through 2004 when DOE funding ended our partnership awarded 41 DOE-Energy Bioscience Fellows of the Life Sciences Research Foundation. Each of these was a three year fellowship. DOE-Energy Biosciences was well matched with LSRF. Our extensive peer review screened applicants in all areas of the life sciences. Most LSRF sponsors are interested in supporting fellows who work on diseases. At the time that we began our partnership with DOE we had no sponsors willing to support plant biology and non medical microbiology. For 15 years DOE played a major role in the training of the very best young scientists in these important fields of research simply through its support of LSRF post doctoral fellows.

    D + s mesons produced in Z 0 →b anti b events were separated from the Z 0 →c anti c component using a lifetime tag. Using a sample of 1.5 million hadronic Z decays collected with the ALEPH detector the anti B 0 s and D + s yields have been measured: B(b→ anti B 0 s )B(anti B 0 s →D + s )=0.088±0.020(stat.)±0.020(syst.), B(c→D + s )=0.128±0.019(stat.) +0.019 -0.016 (syst.). The anti B 0 s lifetime was measured in a anti B 0 s enriched sample reconstructing the decay length from the vertex of the D + s with a hadron from the anti B 0 s decay. The result obtained is: τ B s =1.61 +0.30 -0.29 (stat.) +0.18 -0.16 (syst.) ps. (orig.)

    1999-01-01

    The general audience for these lectures is mainly physicists, computer scientists, engineers or the general public wanting to know more about what’s going on in the biosciences. What’s bioinformatics and why is all this fuss being made about it ? What’s this revolution triggered by the human genome project ? Are there any results yet ? What are the problems ? What new avenues of research have been opened up ? What about the technology ? These new developments will be compared with what happened at CERN earlier in its evolution, and it is hoped that the similiraties and contrasts will stimulate new curiosity and provoke new thoughts.

  5. Study of the Z+b anti b production with the ATLAS detector at the LHC

    International Nuclear Information System (INIS)

    Vladoiu, Dan Nicolae

    2013-01-01

    A first inclusive measurement of the production cross-section for a Z boson in association with a bottom-antibottom quark pair at √(s)=7 TeV at the Large Hadron Collider is presented, using the full dataset of ∫L(t)dt=4.64 pb -1 collected by the ATLAS detector during the year 2011. Such a measurement provides a direct test of perturbative quantum chromodynamics predictions, and, for production of a Higgs boson in association with a Z boson, Z+b anti b represents the highest irreducible background. The decay channels of the Z boson considered are: Z→e + e - and Z→μ + μ - For the reconstruction of the Z boson candidate, exactly two leptons with opposite charge and of the same-flavor are required to have an invariant mass within 76 GeV-106 GeV. Jets with weakly decaying b-hadrons are selected with a b-tagging algorithm at 75% efficiency. For the reduction of the top-antitop background, events are required to have a missing transverse energy of less than 30 GeV. The extraction of the signal cross-section from the data sample was realized with a binned likelihood template fit method, using as template fit a strong discriminant between heavy-flavor and charm/light-flavor jets. Three exclusive templates are produced: ''bb''-events with a Z boson candidate and at least two identified b-jets, obtained from simulated samples with a Z boson and heavy b-jets; ''non-bb''-events with a Z boson candidate and less than two identified b-jets, derived from simulated samples with a Z boson and light-jets, and ''other'' - events with a Z boson candidate and any number of b-jets created from simulated top-antitop and diboson samples. The sum of the three template distributions was fit to the data keeping the normalization of the other template fixed and floating the normalization of the bb and non - bb templates. The measured cross-section results in the electron and muon channels are: σ(Z +b anti b).Br(Z→e + e - )=436.3±32.4(stat.) +52.3 -50.3 (syst.)±7.9 (lumi.) fb,

  6. Search for Higgs-boson production in association with top-quark pairs in H→b anti b decays at √(s)=8 and 13 TeV with the CMS experiment

    International Nuclear Information System (INIS)

    Garay Garcia, Jasone

    2016-08-01

    A search of the Higgs boson in association with a top-quark pair is presented, using pp collision data collected by the CMS detector at centre-of-mass energies of 8 and 13 TeV corresponding to integrated luminosities of 19.7 fb -1 and 2.6 fb -1 , respectively. Candidate t anti tH events are selected to enhance the dileptonic decay channel of the t anti t system and the decay of the Higgs boson into two b-quark jets (H→b anti b). The final state of the selected t anti tH(b anti b) processes is characterised by the presence of four b-jets, two originating from the t anti t system and two belonging to the Higgs-boson decay. The b-quark jet pair originating from the t anti t system is identified using multi-variate analysis techniques. In order to reduce the combinatorial background provided by the four b-jets in the final state, a generic method is developed to get an optimal separation between b and anti b jets. The remaining b-jets in the event are used to reconstruct the (m b anti b ) invariant-mass distribution used to estimate the resonant signal above the non-resonant background and to determine the upper-limit on the t anti tH (b anti b) production. A combined fit to the data in two different categories results in an observed (expected) upper limit of μ<10.9(12.0) (for 8 TeV), and μ<13.4(14.4) (for 13 TeV) at the 95 % confidence level, where μ is the ratio of the observed t anti tH production cross section relative to the value expected for a Standard Model Higgs boson with m H =125 GeV.

    Full Text Available This study was aimed at comparing the influence of anti bZP3’s passive immunization on anti-anti bZP3’s titer and pregnancy level on Wistar rats and mice. This study employed factorial design experiment with completely randomized design. The first factor was immunogenic type. The treated rats were immunized with 100 L anti bZP3 in 100 L Complete Freund’s Adjuvant (CFA, while the treated mice were injected with 50 L anti bZP3 in 50 L CFA. Control Wistar rats and mice were immunized with CFA and Incomplete Freund’s Adjuvant (IFA without anti bZP3. The second factor was animal type. The third factor was the length of serum incubation, i.e. 38, 49, 63, 86, 100, and 126 d. Dot blot on the treated Wistar rats and mice showed positive response proven by blue gradation; pre-immune mice as well as control Wistar rats and mice showed negative response proven by white gradation. The highest antibody titer in treated mouse serum was shown in 63 d incubation.

    Combining our results for various O(α 2 s ) corrections to the weak radiative B-meson decay, we are able to present the first estimate of the branching ratio at the next-to-next-to-leading order in QCD. We find B(anti B → X s γ)=(3.15±0.23) x 10 -4 for E γ >1.6 GeV in the anti B-meson rest frame. The four types of uncertainties: non-perturbative (5%), parametric (3%), higher-order (3%) and m c -interpolation ambiguity (3%) have been added in quadrature to obtain the total error. (orig.)

    Motivated by the rapid development of heavy-flavor experiments, phenomenological studies of nonleptonic anti B_d_,_s → D"*_d_,_sV and anti B"*_d_,_s → D_d_,_sV (V = ρ, K*) decays are performed within the framework of QCD factorization. Relative to the previous work, the QCD corrections to the transverse amplitudes are evaluated at next-to-leading order. The theoretical predictions of the observables are updated. For the measured anti B_d_,_s → D"*_d_,_sV decays, the tensions between theoretical results and experimental measurements, i.e. the ''R_d_s"V puzzle'' and ''D*V (or R_V_/_l _a_n_t_i _ν__l_) puzzle'', are presented after detailed analyses. For the anti B"*_d_,_s → D_d_,_sV decays, they have relatively large branching fractions of the order >or similar O(10"-"9) and are in the scope of Belle-II and LHCb experiments. Moreover, they also provide a way to crosscheck the possible puzzles mentioned above through the similar ratios R_d_s"'"V and R"'_V_/_l _a_n_t_i _ν__l_. More refined experimental measurements and theoretical efforts are required to confirm or refute such two anomalies. (orig.)

    We investigate the decay of anti B{sup 0} → anti K{sup *0}R and anti B{sub s}{sup 0} → φR with R being the X(4160), Y(3940), Z(3930) resonances. Under the assumption that these states are dynamically generated from the vector-vector interaction, as has been concluded from several theoretical studies, we use a reaction mechanism of quark production at the elementary level, followed by hadronization of one final q anti q pair into two vectors and posterior final state interaction of this pair of vector mesons to produce the resonances. With this procedure we are able to predict five ratios for these decays, which are closely linked to the dynamical nature of these states, and also predict the order of magnitude of the branching ratios which we find of the order of 10{sup -4}, well within the present measurable range. In order to further test the dynamical nature of these resonances we study the anti B{sub s}{sup 0} → φ D* anti D* and anti B{sub s}{sup 0} → φ D{sub s}{sup *} anti D{sub s}{sup *} decays close to the D* anti D* and D{sub s}{sup *} anti D{sub s}{sup *} thresholds and make predictions for the ratio of the mass distributions in these decays and the anti B{sub s}{sup 0} → φR decay widths. The measurement of these decays rates can help unravel the nature of these resonances. (orig.)

    In this communication, we introduce a general framework and discussion on the role of models and the modeling process in the field of biosciences. The objective is to sum up the common procedures during the formalization and analysis of a biological problem from the perspective of Systems Biology, which approaches the study of biological systems as a whole. We begin by presenting the definitions of (biological) system and model. Particular attention is given to the meaning of mathematical model within the context of biology. Then, we present the process of modeling and analysis of biological systems. Three stages are described in detail: conceptualization of the biological system into a model, mathematical formalization of the previous conceptual model and optimization and system management derived from the analysis of the mathematical model. All along this work the main features and shortcomings of the process are analyzed and a set of rules that could help in the task of modeling any biological system are presented. Special regard is given to the formative requirements and the interdisciplinary nature of this approach. We conclude with some general considerations on the challenges that modeling is posing to current biology.

    The field of epigenetics is now on a geometric rise, driven in a large part by the realization that modifiers of chromatin are key regulators of biological processes in vivo. The three major classes of epigenetic effectors are DNA methylation, histone post-translational modifications (such as acetylation, methylation or phosphorylation) and small noncoding RNAs (most notably microRNAs). In this article, I report from Select Biosciences Epigenetics Europe 2010 industry conference held on 14-15 September 2010 at The Burlington Hotel, Dublin, Ireland. This industry conference was extremely well attended with a global pool of delegates representing the academic research community, biotechnology companies and pharmaceutical companies, as well as the technology/tool developers. This conference represented the current state of the epigenetics community with cancer/oncology as a key driver. In fact, it has been estimated that approximately 45% of epigenetic researchers today identify cancer/oncology as their main area of focus vis-à-vis their epigenetic research efforts.

    In May 2002, the United States Department of Energy (DOE) signed Assistance Instrument Number DE-FC09-02CH11109 with the Medical University of South Carolina (MUSC) to support the Environmental Biosciences Program (EBP). This funding instrument replaces DOE Assistance Instrument Number DE-FC02-98CH10902. EBP is an integrated, multidisciplinary scientific research program, employing a range of research initiatives to identify, study and resolve environmental health risks. These initiatives are consistent with the MUSC role as a comprehensive state-supported health sciences institution and with the nation's need for new and better approaches to the solution of a complex and expansive array of environment-related health problems. The intrinsic capabilities of a comprehensive health sciences institution enable MUSC to be a national resource for the scientific investigation of environmental health issues. EBPs success as a nationally prominent research program is due, in part, to its ability to task-organize scientific expertise from multiple disciplines in addressing these complex problems. Current research projects have focused EBP talent and resources on providing the scientific basis for risk-based standards, risk-based decision making and the accelerated clean-up of widespread environmental hazards. These hazards include trichloroethylene (TCE), polychlorinated biphenyls (PCBs), and low-dose ionizing radiation. A project is also being conducted in the use of geographical information system technology to analyze population health risks related to environmental hazards as a tool for risk-based decision-making.

    We study the spectroscopy and dominant decays of the bottomonium-like tetraquarks (bound diquarks-antidiquarks), focusing on the lowest lying P-wave [bq][anti b anti q] states Y [bq] (with q=u,d), having J PC =1 -- . To search for them, we analyse the BABAR data obtained during an energy scan of the e + e - →b anti b cross section in the range of √(s)=10.54 to 11.20 GeV. We find that these data are consistent with the presence of an additional b anti b state Y [bq] with a mass of 10.90 GeV and a width of about 30 MeV apart from the Υ(5S) and Υ(6S) resonances. A closeup of the energy region around the Y [bq] -mass may resolve this state in terms of the two mass eigenstates, Y [b,l] and Y [b,h] , with a mass difference, estimated as about 6 MeV. We tentatively identify the state Y [bq] (10900) from the R b -scan with the state Y b (10890) observed by BELLE in the process e + e - →Y b (10890)→Υ(1S,2S)π + π - due to their proximity in masses and decay widths.

  8. Search for a light Higgs boson in the channel WH→ eνe b anti b in p anti p collisions at √(s)=1.96 TeV at the DO detector of the Tevatron

    2005-01-01

    Although the standard model of particle physics has been very successfull in describing nature it needs to be extended by the Higgs mechanism to explain the particle masses observed in experiments. This mechanism introduces a new elementary particle called the Higgs boson. Current research at particle accelerators focuses on the search for the Higgs boson as a major goal. This analysis uses the data recorded with the D0-detector of the Tevatron at the Fermi National Accelerator Laboratory (FNAL). The Tevatron collides protons and antiprotons at a center of mass energy of √(s)=1.96 TeV. The primary goal of the analysis was the search for a light Higgs boson in the WH channel. For this the process p anti p→WH→eνb anti b was used. Furthermore a measurement of the Wb anti b production cross section has been performed. For the measurements a total integrated luminosity of L=255 pb -1 was available. For the selection of the desired processes events with electrons, missing transverse momentum and at least two jets have been used. At least two of the jets were required to be identified as b-jets. To obtain an efficient event selection many event properties had to be calculated and methods to cut on them needed to be optimized. Based on the selected events the Wb anti b production cross section has been calculated. After including the branching ratio BR(W→eν)=0.108 the result is σ(Wb anti b)=21.8 pb +15.5 -20.0 pb(sys+stat) for events where the b-quarks satisfy p T >8 GeV und η 95 (Wb anti b)=60.9 pb has been obtained. The same basic event selection has been used to obtain an upper limit for the WH production cross section. For the statistical analysis of these events the method of Cousins and Feldman was used. This method was extended to include background uncertainties as proposed by Conrad et al. Finally for a standard model Higgs boson of 115 GeV mass an upper limit for the production cross section of σ 95 (WH)=12.2 pb has been obtained at a confidence

  9. A measurement of the B0 anti B0 mixing parameter at LEP using a neural network

    International Nuclear Information System (INIS)

    Los, M.E.

    1995-01-01

    In this thesis the B 0 - anti B 0 mixing parameter χ is measured. The data have been collected using the DELPHI detector at the electron-positron accelerator LEP at CERN in Geneva. At the LEP energy of about 91 GeV the Z 0 particle is produced. About 15 percent of the time the Z 0 decays into a b anti b-pair, which makes LEP an ideal environment to study the properties of the heavy b quark. In this thesis, the signal for the measurement of χ consists of events in which there are two leptons in the final state. If both leptons directly originate from a b quark decay (b→l), then their charge reflects the one of the b quark. Events with leptons of the same sign indicate the presence of B 0 - anti B 0 mixing. The neural network variable achieves a better separation between the signal and the background than the transverse moemntum. Using data recorded by DELPHI in 1992, one obtains for the mixing parameter χ=8.6%±2.3%(stat)±0.6%(sys). (orig./WL)

    We study the spectroscopy and dominant decays of the bottomonium-like tetraquarks (bound diquarks-antidiquarks), focusing on the lowest lying P-wave [bq][anti b anti q] states Y{sub [bq]} (with q=u,d), having J{sup PC}=1{sup --}. To search for them, we analyse the BABAR data obtained during an energy scan of the e{sup +}e{sup -}{yields}b anti b cross section in the range of {radical}(s)=10.54 to 11.20 GeV. We find that these data are consistent with the presence of an additional b anti b state Y{sub [bq]} with a mass of 10.90 GeV and a width of about 30 MeV apart from the {upsilon}(5S) and {upsilon}(6S) resonances. A closeup of the energy region around the Y{sub [bq]}-mass may resolve this state in terms of the two mass eigenstates, Y{sub [b,l]} and Y{sub [b,h]}, with a mass difference, estimated as about 6 MeV. We tentatively identify the state Y{sub [bq]}(10900) from the R{sub b}-scan with the state Y{sub b}(10890) observed by BELLE in the process e{sup +}e{sup -}{yields}Y{sub b}(10890){yields}{upsilon}(1S,2S){pi}{sup +}{pi}{sup -} due to their proximity in masses and decay widths.

    We present up-to-date matched predictions for the b anti bH inclusive cross section at the LHC at √(s)=13 TeV. Using a previously developed method, our predictions consistently combine the complete NLO contributions that are present in the 4-flavor scheme calculation, including finite b-quark mass effects as well as top-loop induced Y{sub b}Y{sub t} interference contributions, with the resummation of collinear logarithms of m{sub b}/m{sub H} as present in the 5-flavor scheme calculation up to NNLO. We provide a detailed estimate of the perturbative uncertainties of the matched result by examining its dependence on the factorization and renormalization scales, the scale of the Yukawa coupling, and also the low b-quark matching scale in the PDFs. We motivate the use of a central renormalization scale of m{sub H}/2, which is halfway between the values typically chosen in the 4-flavor and 5-flavor scheme calculations. We evaluate the parametric uncertainties due to the PDFs and the b-quark mass, and in particular discuss how to systematically disentangle the parametric m{sub b} dependence and the unphysical b-quark matching scale dependence. Our best prediction for the b anti bH production cross section in the Standard Model at 13 TeV and for m{sub H}=125 GeV is σ(b anti bH)=.52pb[1±9.6%(perturbative){sup +2.9%}{sub -3.6%}(parametric)]. We also provide predictions for a range of Higgs masses m{sub H} element of [50,750] GeV. Our method to compute the matched prediction and to evaluate its uncertainty can be readily applied to other heavy-quark-initiated processes at the LHC.

    Full Text Available Objective: To investigate the reliability of the immunoblot method in the detection of serum immunoreactivity towards the B/B’ polypeptides of U small nuclear ribonucleoproteins (UsnRNP and to assess the significance of these antibodies in connective tissue disease (CTD patients. Methods: We tested the sera of 348 patients with CTD (101 SLE, 51 systemic sclerosis, 53 primary Sjogren’s syndrome, 27 poly/dermatomyositis, 15 rheumatoid arthritis and 101 overlap CTD, of 31 matched healthy subjects and 13 patients with primary Epstein-Barr virus (EBV infection with high titre IgG anti-EBV antibodies. IgG anti-UsnRNP antibodies were determined by immunoblotting on nuclear extract from Raji cells (an EBV-immortalised human B lymphoid cell line and Jurkat cells (a human T lymphoid cell line. Anti-dsDNA antibodies were detected by indirect immunofluorescence on Crithidia luciliae and anti-ENA by counterimmunoelectrophoresis. Anti-dsDNA activity and avidity were measured in SLE sera by ELISA with Scatchard analysis. Results were statistically analysed by chi-square and Mann-Whitney tests. Results: A high frequency of anti-B/B’ antibodies was found in the sera of CTD patients, confined to SLE (54.4% and overlap CTD with SLE features (55,2%. Anti-B/B’ immune reactivity was closely associated with other anti-UsnRNP specificities, gel precipitating anti-nRNP and anti-P antibodies. Nine out of 15 (60% anti-B/B’ positive/anti-ENA negative lupus sera on Raji blots were confirmed to be positive also on Jurkat blots. The sera from patients with EBV infection provided, on Raji blots, completely different band patterns from those obtained with auto-immune sera. Conclusions. The Sm B/B’ proteins are the predominant or, at least, the most frequently targeted antigens of the UsnRNP auto-immune response in SLE and “lupus-like” overlap CTD. Moreover, anti-B/B’ is diagnostically specific for CTD with SLE features. Immunoblotting on human B lymphoid cells

  18. Consequences of R-parity violating interactions for anomalies in anti B → D(*)τ anti ν and b → sμ+μ-

    International Nuclear Information System (INIS)

    Deshpande, N.G.; He, Xiao-Gang

    2017-01-01

    We investigate the possibility of explaining the enhancement in semileptonic decays of anti B → D (*) τ anti ν, the anomalies induced by b → sμ + μ - in anti B → (K, K*, φ)μ + μ - and violation of lepton universality in R K = Br(anti B → Kμ + μ - )/Br(anti B → Ke + e - ) within the framework of R-parity violating MSSM. The exchange of down type right-handed squark coupled to quarks and leptons yields interactions which are similar to leptoquark induced interactions that have been proposed to explain the anti B → D (*) τ anti ν by tree level interactions and b → sμ + μ - anomalies by loop induced interactions, simultaneously. However, the Yukawa couplings in such theories have severe constraints from other rare processes in B and D decays. Although this interaction can provide a viable solution to the R(D (*) ) anomaly, we show that with the severe constraint from anti B → Kν anti ν, it is impossible to solve the anomalies in the b → sμ + μ - process simultaneously.

    The field of bioscience methodologies in physical chemistry stands at the intersection of the power and generality of classical and quantum physics with the minute molecular complexity of chemistry and biology. This book provides an application of physical principles in explaining and rationalizing chemical and biological phenomena. It does not stick to the classical topics that are conventionally considered as part of physical chemistry; instead it presents principles deciphered from a modern point of view, which is the strength of this book.

    Grillo, Lucia

    2015-07-22

    This thesis presents the measurement of the CP-violating asymmetry in B{sup 0}- anti B{sup 0} mixing using data corresponding to an integrated luminosity of 3.0 fb{sup -1} collected at the LHCb experiment in proton-proton collisions at the center-of-mass energies of 7 TeV and 8 TeV. This analysis uses untagged, semileptonic B{sup 0}→D{sup -}μ{sup +}ν{sup -} and B{sup 0}→D{sup *-}μ{sup +}ν{sup -} decays, where the D{sup -} decays into K{sup +}π{sup -}π{sup -}, and the D{sup *-} decays into anti D{sup 0}(→ K{sup +}π{sup -})π{sup -}. The neutrino in the semileptonic B decays is not reconstructed. A decay time dependent fit allows to disentangle the CP asymmetry from the possible B{sup 0}- anti B{sup 0} production asymmetry. Detection and reconstruction asymmetries are calibrated using promptly produced Cabibbo-favored D{sup +} decays, and inclusive secondary J/ψ decays. The CP-violating asymmetry is measured to be a{sup d}{sub sl}=(-0.02±0.19 (stat)±0.30(syst))%. This result is consistent with the Standard Model prediction, and it is the most precise measurement from a single experiment to date. This measurement is published in Physical Review Letters.

  1. Search for the SM Higgs boson in the channel WH{yields}l{nu}b anti b with the ATLAS experiment at the LHC

    Will, Jonas Zacharias

    2012-11-26

    One of the most important scientific challenges of ATLAS and CMS, multi-purpose detectors at CERN's Large Hadron Collider (LHC), is the discovery or exclusion of the longly sought standard model Higgs boson predicted almost fifty years ago. In summer 2012, both ATLAS and CMS discovered a new particle. Its mass is determined to be 126.0{+-}0.4(stat){+-} 0.4(sys) GeV (ATLAS) and 125.3{+-}0.4(stat){+-}0.5 (sys) GeV. Its further properties are so far consistent with the predicted properties of a standard model Higgs boson within large uncertainties. Besides the Higgs search in the sensitive bosonic channels, H{yields}{gamma}{gamma}, H{yields}ZZ, and H{yields}WW, the fermionic channels H{yields}{tau}{tau} and H{yields}b anti b contributed to the exclusion of a standard model Higgs boson below the observed excess and are essential for measuring the couplings of the new particle to fermions. In the analysis presented here, the associated Higgs production WH in the Higgs decay channel H{yields}b anti b is studied on the collision data corresponding to an integrated luminosity of 4.7 fb{sup -1} recorded by ATLAS in 2011 at a proton-proton centre-of-mass energy of 7 TeV. A cut-based analysis selects events with the signature of interest, consisting of one lepton (electron, muon), missing transverse energy, and two b jets. Techniques for a data-driven estimate of the multijet background are developed, validated and applied. The different contributions from heavy and light flavour jets to the W+jets background are estimated by a data-driven method. Furthermore, the large background components from top and W+jets are normalized using collision data. The invariant mass of the two selected jets m{sub b} {sub anti} {sub b} is used for the determination of exclusion limits on the Higgs signal strength {sigma}/{sigma}{sub WH} in the mass window 110 GeV{<=}m{sub H}{<=}130 GeV. For a hypothesized Higgs mass of m{sub H}=110 GeV, the Higgs signal strength is excluded for values

    We present a particle-level study of the Standard Model non-resonant Higgs-pair production process in the b anti bb anti b final state, at the Large Hadron Collider at √(s) = 14 TeV. Each Higgs boson is reconstructed from a pair of close-by jets formed with the anti-k{sub t} jet clustering algorithm, with radius parameter R = 0.4. Given the kinematic properties of the produced Higgs bosons, this Higgs reconstruction approach appears to be more suitable than the use of largeradius jets that was previously proposed in the literature.We find that the sensitivity for observing this final state can be improved significantly when the full set of uncorrelated angular and kinematic variables of the 4b system is exploited, leading to a statistical significance of 1.8 per experiment with an integrated luminosity of 3 ab{sup -1}.

    The inclusive decay anti B {yields} X{sub u}l anti {nu} is of much interest because of its potential to constrain the CKM element vertical stroke V{sub ub} vertical stroke. Experimental cuts required to suppress charm background restrict measurements of this decay to the shape-function region, where the hadronic final state carries a large energy but only a moderate invariant mass. In this kinematic region, the differential decay distributions satisfy a factorization formula of the form H.J x S, where S is the non-perturbative shape function, and the object H.J is a perturbatively calculable hard-scattering kernel. In this paper we present the calculation of the hard function H at next-to-next-to-leading order (NNLO) in perturbation theory. Combined with the known NNLO result for the jet function J, this completes the perturbative part of the NNLO calculation for this process. (orig.)

    Despite the success of the Standard Model (SM) all along the last fifty years, conceptual limitations do not allow it to answer to some theoretical questions or justify certain experimental observations. These elements let us think that the SM would be only an approximation at low energy of a more fundamental theory. The challenge of particle physics is to search for new phenomena at high-energy not included in the SM. The unique properties of the top quark make it an outstanding tool to probe new dynamics beyond the SM, where it should play a key role, especially by coupling to new heavy resonances. This presentation will report on searches for new heavy charged vector or scalar bosons, usually called W{sup '} and H{sup +}, decaying into a top and a bottom quark through effective coupling approaches, in lepton plus jets final states. These searches are performed with 20.3 fb{sup -1} of proton collision data, produced by the LHC at Run I, at a center-of-mass energy of 8 TeV and collected by the ATLAS detector in 2012. This talk intends to present the analysis strategy using multivariate techniques based on boosted decision trees to search for an excess of W{sup '} or H{sup +} signal processes in the recorded data, and the statistical analysis performed to extract exclusion limits on the mass, the production cross section or the effective couplings of these particles. It finally concludes on the perspectives of these searches at the LHC Run II.

    When reading bioscience journal articles, many researchers focus attention on the figures and their captions. This observation led to the development of the BioText literature search engine, a freely available Web-based application that allows biologists to search over the contents of Open Access Journals, and see figures from the articles displayed directly in the search results. This article presents a qualitative assessment of this system in the form of a usability study with 20 biologist participants using and commenting on the system. 19 out of 20 participants expressed a desire to use a bioscience literature search engine that displays articles' figures alongside the full text search results. 15 out of 20 participants said they would use a caption search and figure display interface either frequently or sometimes, while 4 said rarely and 1 said undecided. 10 out of 20 participants said they would use a tool for searching the text of tables and their captions either frequently or sometimes, while 7 said they would use it rarely if at all, 2 said they would never use it, and 1 was undecided. This study found evidence, supporting results of an earlier study, that bioscience literature search systems such as PubMed should show figures from articles alongside search results. It also found evidence that full text and captions should be searched along with the article title, metadata, and abstract. Finally, for a subset of users and information needs, allowing for explicit search within captions for figures and tables is a useful function, but it is not entirely clear how to cleanly integrate this within a more general literature search interface. Such a facility supports Open Access publishing efforts, as it requires access to full text of documents and the lifting of restrictions in order to show figures in the search interface.

    The possible neutral D{sup (*)} anti D{sup (*)} and B{sup (*)} anti B{sup (*)} molecular states are studied in the framework of the constituent quark models, which is extended by including the s-channel one-gluon exchange. Using different types of quark-quark potentials, we solve the four-body Schroedinger equation by means of the Gaussian expansion method. The bound states of D{sup (*)} anti D{sup (*)} with J{sup PC} = 1{sup ++}, 2{sup ++} and B{sup (*)} anti B{sup (*)} with J{sup PC} = 0{sup ++}, 1{sup +-}, 1{sup ++}, 2{sup ++} are obtained. The molecular states D* anti D with J{sup PC} = 1{sup ++} and B* anti B with J{sup PC} = 1{sup +-} are good candidates for X(3872) and Z{sup 0}{sub b}(10610), respectively. The dependence of the results on the model parameters is also discussed. (orig.)

    The author argue that a small or large CP-violating asymmetry in B d 0 vs (anti B) d 0 →J/ψK s decays, which seems to be favored by the recent BaBar or Belle data, might hint at the existence of new physics in B d 0 -(anti B) d 0 mixing. The authors present a model-independent framework to show how new physics modifies the standard-model CP-violating asymmetry. The particularly emphasize that the consistent of cp-violating asymmetry experimental result with standard model prediction must not imply the absence of new physics in B d 0 -(anti B) d 0 mixing

  1. b-baryon light-cone distribution amplitudes and a dynamical theory for [bq] [ anti b anti q]-tetraquarks

    International Nuclear Information System (INIS)

    Hambrock, Christian

    2011-04-01

    In my thesis I present our work on the bottom-baryon light-cone distribution amplitudes (LCDAs) and on the [bq][ anti b anti q]-tetraquarks. For the former we extended the known LCDAs for the ground state baryon Λ b to the entire b-baryon ground state multiplets and included s-quark mass-breaking effects. The LCDAs form crucial input for the calculations of characteristic properties of b-baryon decays. In this context they can for example be used in the calculation of form factors for semileptonic flavor-changing neutral-current (FCNC) decays. For the [bq][ anti b anti q]-tetraquarks, we calculated the tetraquark mass spectrum for all quarks q=u,d,s,c in a constituent Hamiltonian quark model. We estimated the electronic width by introducing a generalized Van Royen-Weisskopf formula for the tetraquarks, and evaluated the partial hadronic two-body and total decay widths for the tetraquarks with quantum numbers J PC =1 -- . With this input, we performed a Breit-Wigner fit, including the tetraquark contributions, to the inclusive R b -spectrum measured by BaBar. The obtained χ 2 /d.o.f. of the BaBar R b -scan data is fairly good. The resulting fits are suggestive of tetraquark states but not conclusive. We developed a model to describe the transitions e + e - →Y b →Υ(nS)(π + π - ,K + K - ,ηπ 0 ), in which Y b is a 1 -- tetraquark state. The model includes the exchange of light tetraquark and meson states. We used this model to fit the invariant-mass and helicity spectra for the dipionic final state measured by Belle and used the results to estimate the spectra of the channels e + e - →Y b →Υ(nS)(K + K - ,ηπ 0 ). The spectra are enigmatic in shape and magnitude and defy an interpretation in the framework of the standard bottomonia, requesting either an interpretation in terms of exotic states, such as tetraquarks, or a radical alteration of the, otherwise successful, QCD-based bottomonium-model. The tetraquark hypothesis describes the current data well

  3. Factorization and non-local 1/mb corrections in the decay anti B → Xsγ

    International Nuclear Information System (INIS)

    Benzke, Michael

    2011-01-01

    In this thesis, a systematic analysis of the anti B → X s γ photon spectrum in the endpoint region is presented. The endpoint region refers to a kinematic configuration of the final state, in which the photon has a large energy m b -2E γ =O(Λ QCD ), while the jet has a large energy but small invariant mass. Using methods of soft-collinear effective theory and heavy-quark effective theory, it is shown that the spectrum can be factorized into hard, jet, and soft functions, each encoding the dynamics at a certain scale. The relevant scales in the endpoint region are the heavy-quark mass m b , the hadronic energy scale Λ QCD and an intermediate scale √(Λ QCD m b ) associated with the invariant mass of the jet. It is found that the factorization formula contains two different types of contributions, distinguishable by the space-time structure of the underlying diagrams. On the one hand, there are the direct photon contributions which correspond to diagrams with the photon emitted directly from the weak vertex. The resolved photon contributions on the other hand arise at O(1/m b ) whenever the photon couples to light partons. In this work, these contributions are explicitly defined in terms of convolutions of jet functions with subleading shape functions. While the direct photon contributions can be expressed in terms of a local operator product expansion, when the photon spectrum is integrated over a range larger than the endpoint region, the resolved photon contributions always remain non-local. Thus, they are responsible for a non-perturbative uncertainty on the partonic predictions. In this thesis, the effect of these uncertainties is estimated in two different phenomenological contexts. First, the hadronic uncertainties in the anti B → X s γ branching fraction, defined with a cut E γ > 1.6GeV are discussed. It is found, that the resolved photon contributions give rise to an irreducible theory uncertainty of approximately 5%. As a second application of

    The 'optimal' factorization scale μ{sub 0} is calculated for open heavy quark production. We find that the optimal value is μ{sub F} = μ{sub 0} ≅ 0.85√(p{sup 2}{sub T}+m{sub Q}{sup 2}); a choice which allows us to resum the double-logarithmic, (α{sub s} ln μ{sup 2}{sub F} ln (1/x)){sup n} corrections (enhanced at LHC energies by large values of ln(1/x)) and to move them into the incoming parton distributions, PDF (x, μ{sub 0}{sup 2}). Besides this result for the single inclusive cross section (corresponding to an observed heavy quark of transverse momentum p{sub T}), we also determined the scale for processes where the acoplanarity can be measured; that is, events where the azimuthal angle between the quark and the antiquark may be determined experimentally. Moreover, we discuss the important role played by the 2 → 2 subprocesses, gg → Q anti Q at NLO and higher orders. In summary, we achieve a better stability of the QCD calculations, so that the data on c anti c and b anti b production can be used to further constrain the gluons in the small x, relatively low scale, domain, where the uncertainties of the global analyses are large at present.

  5. The decays anti B → anti K{sup (*)}l{sup +}l{sup -} at low recoil and their constraints on new physics

    Dyk, Danny van

    2012-07-15

    In this thesis we test the validity of the Standard Model of particle physics by studying the exclusive rare decays anti B → anti K{sup (*)}l{sup +}l{sup -}. We calculate the angular distribution of the decay anti B → anti K{sup (*)}l{sup +}l{sup -} in the most general basis of effective operators. We obtain results for the angular distribution in the kinematic region of low hadronic recoil. Based on our results for the angular distribution, we propose observables which exhibit no or only very weak dependence on hadronic matrix elements. Beyond CP-averaged observables, we also investigate direct and mixing induced CP asymmetries at low hadronic recoil. We conclude our investigation of exclusive decays by studying the decay anti B → anti Kl{sup +}l{sup -}, where we find a relation between the CP asymmetry of the rates of anti B → anti K{sup (*)}l{sup +}l{sup -}. Standard model results for a majority of our analytic results are given. Beyond that, we perform a model-independent analysis based on available experimental data and obtain constraints on the Wilson coefficients C{sub 9} and C{sub 10}, as well as lower bounds on the zero-crossing in the anti B → anti K*l{sup +}l{sup -} forward-backward asymmetry. Based on recent LHC data we find two disjoint solutions for the Wilson coefficients. One of the solutions is in good agreement with the Standard Model, but sizable deviations are still allowed.

  6. Applications of computational tools in biosciences and medical engineering

    Altenbach, Holm

    2015-01-01

     This book presents the latest developments and applications of computational tools related to the biosciences and medical engineering. It also reports the findings of different multi-disciplinary research projects, for example, from the areas of scaffolds and synthetic bones, implants and medical devices, and medical materials. It is also shown that the application of computational tools often requires mathematical and experimental methods. Computational tools such as the finite element methods, computer-aided design and optimization as well as visualization techniques such as computed axial tomography open up completely new research fields that combine the fields of engineering and bio/medical. Nevertheless, there are still hurdles since both directions are based on quite different ways of education. Often even the “language” can vary from discipline to discipline.

    The author presents a measurement of σ(b anti b)/σ(q anti q) in the annihilation process e + e - → q anti q → hadrons at √s = 29 GeV. The analysis is based on 66 pb -1 of data collected between 1984 and 1986 with the TPC/2γ detector at PEP. To identify bottom events, he uses a neural network with inputs that are computed from the 3-momenta of all of the observed charged hadrons in each event. He also presents a study of bias in techniques for measuring inclusive π ± , K ± , and p/anti p production in the annihilation process e + e - → b anti b → hadrons at √s = 29 GeV, using a neural network to identify bottom-quark jets. In this study, charged particles are identified by a simultaneous measurement of momentum and ionization energy loss (dE/dx)

We assume the B{sup *} anti B{sup *} system forming a cluster, and in terms of the two-body ρB{sup *} unitarized scattering amplitudes in the local hidden gauge approach we find a new I(J{sup PC}) = 1(3{sup -}) state. The mass of the new state corresponds to a two-particle invariant mass of the ρB{sup *} system close to the resonant energy of the *, indicating that the role of this J = 2 resonance is important in the dynamical generation of the new state.

After having recalled the theoretical background and previous measurements, it describes precisely the selection of prompt electrons from B hadrons. The muon's one is recalled.

    To evaluate the use of LabTutor (a physiological data capture and e-learning package) in bioscience education for student nurses. Knowledge of biosciences is important for nurses the world over, who have to monitor and assess their patient's clinical condition, and interpret that information to determine the most appropriate course of action. Nursing students have long been known to find acquiring useable bioscience knowledge challenging. Blended learning strategies are common in bioscience teaching to address the difficulties students have. Student nurses have a preference for hands-on learning, small group sessions and are helped by close juxtaposition of theory and practice. An evaluation of a new teaching method using in-classroom voluntary questionnaire. A structured survey instrument including statements and visual analogue response format and open questions was given to students who participated in Labtutor sessions. The students provided feedback in about the equipment, the learning and the session itself. First year (n = 93) and third year (n = 36) students completed the evaluation forms. The majority of students were confident about the equipment and using it to learn although a few felt anxious about computer-based learning. They all found the equipment helpful as part of their bioscience education and they all enjoyed the sessions. This equipment provides a helpful way to encourage guided independent learning through practice and discovery and because each session is case study based and the relationship of the data to the patient is made clear. Our students helped to evaluate our initial use of LabTutor and found the sessions enjoyable and helpful. LabTutor provides an effective learning tool as part of a blended learning strategy for biosciences teaching. Improving bioscience knowledge will lead to a greater understanding of pathophysiology, treatments and interventions and monitoring. © 2016 John Wiley & Sons Ltd.

  13. A measurement of the B{sup 0} anti B{sup 0} mixing parameter at LEP using a neural network

    Los, M E

    1995-11-27

    In this thesis the B{sup 0}- anti B{sup 0} mixing parameter {chi} is measured. The data have been collected using the DELPHI detector at the electron-positron accelerator LEP at CERN in Geneva. At the LEP energy of about 91 GeV the Z{sup 0} particle is produced. About 15 percent of the time the Z{sup 0} decays into a b anti b-pair, which makes LEP an ideal environment to study the properties of the heavy b quark. In this thesis, the signal for the measurement of {chi} consists of events in which there are two leptons in the final state. If both leptons directly originate from a b quark decay (b{yields}l), then their charge reflects the one of the b quark. Events with leptons of the same sign indicate the presence of B{sup 0}- anti B{sup 0} mixing. The neural network variable achieves a better separation between the signal and the background than the transverse moemntum. Using data recorded by DELPHI in 1992, one obtains for the mixing parameter {chi}=8.6%{+-}2.3%(stat){+-}0.6%(sys). (orig./WL).

    1993-07-01

    A complete tree-level calculation of the reaction e + e - →μ + μ - b anti b in the electroweak standard theory for the energy range of LEP200 and the Next Linear Collider is presented. The matrix elements have been calculated by employing the computer program CompHEP, the phase space integrals by the Monte Carlo integrator and event generator BASES/SPRING. The dependence of the 4-fermion cross section on energy, Higgs boson mass and Higgs width is studied in detail. Interference contributions between the various diagrams are found not to alter significantly the production and decay distributions of the Higgs boson. It is shown that already the counting rate of the reaction e + e - →μ + μ - b anti b at LEP200 can provide evidence for the existence of the Higgs boson. The dependence of the μ + μ - b anti b cross section on the Higgs width will allow to extract information on this width in particular at LEP200 energies. (orig.)

    2014-02-01

    Full Text Available In the last decade the number of bioscience journals has increased enormously, with many filling specialised niches reflecting new disciplines and technologies. The emergence of open-access journals has revolutionised the publication process, maximising the availability of research data. Nevertheless, a wealth of evidence shows that across many areas, the reporting of biomedical research is often inadequate, leading to the view that even if the science is sound, in many cases the publications themselves are not “fit for purpose”, meaning that incomplete reporting of relevant information effectively renders many publications of limited value as instruments to inform policy or clinical and scientific practice [1–21]. A recent review of clinical research showed that there is considerable cumulative waste of financial resources at all stages of the research process, including as a result of publications that are unusable due to poor reporting [22]. It is unlikely that this issue is confined to clinical research [2–14,16–20].

    2017-08-15

    Inquiry-driven learning, research internships and course-based undergraduate research experiences all represent mechanisms through which educators can engage undergraduate students in scientific research. In life sciences education, the benefits of undergraduate research have been thoroughly evaluated, but limitations in infrastructure and training can prevent widespread uptake of these practices. It is not clear how faculty members can integrate complex laboratory techniques and equipment into their unique context, while finding the time and resources to implement undergraduate research according to best practice guidelines. This review will go through the trends and patterns in inquiry-based undergraduate life science projects with particular emphasis on molecular biosciences-the research-aligned disciplines of biochemistry, molecular cell biology, microbiology, and genomics and bioinformatics. This will provide instructors with an overview of the model organisms, laboratory techniques and research questions that are adaptable for semester-long projects, and serve as starting guidelines for course-based undergraduate research. © FEMS 2017.

    The mission of the Energy Biosciences program is to generate fundamental information about plants and non-health related microorganisms that will constitute the base for new biotechnologies as well as supply information to improve usages of such organisms in their current form. The collective aims are totally consistent with the Department of Energy`s objectives of developing alternate energy sources, replacements for otherwise fossil energy derived products and providing critical fundamental information for the preservation and restoration of environmental conditions affected by energy related activities. The EB program takes full advantage of its organizational locale in the Office of Basic Energy Sciences to directly interact with such disciplines as Materials Sciences, Chemistry, Engineering and Geosciences to promote cross-disciplinary research and planning activities. One of the major specific objectives of the EB program is to probe the enormous capabilities of the specified organisms to carry out biochemical conversions. The limitation to realization of entirely new products and processes via biotechnology is the lack of basic understanding of natural processes. Such knowledge will then afford the advantage of developing procedures to the benefit of people and their society in providing new products along with providing new employment possibilities. This document consists of abstracts of projects supported in FY 1993.

  19. A Search For The Z → b anti-b Process at The D-Zero Experiment

    Jenkins, Amber Helen [Imperial College, London (United Kingdom)

    2006-11-01

    In 2001, the D0 experiment entered a new era. Run II of the Tevatron at the Fermi National Accelerator Laboratory began, and the collider became the highest energy particle accelerator in the world. Accordingly, the D0 detector had already undergone a series of upgrades in order to fully exploit the physics now within reach. These included improvements to the tracking, calorimetry, muon detection and triggering capabilities. In the Standard Model, the Higgs boson is the last piece of the puzzle that remains to be discovered. The Higgs mechanism and consequently the Higgs boson is thought to be the fundamental ingredient by which particles acquire mass, and its existence (or lack of existence) is one of the most pressing issues in particle physics today. As such, one of the main goals of the Run II physics programme at D0 is to search for it. Armed with new accelerator capabilities, D0 will be able to impose tighter constraints on the mass of the Higgs, and perhaps even detect this elusive particle. If the Higgs does exist, it will be extremely difficult to find. One of the main challenges at a hadron-hadron collider is to reduce the large QCD background that masks the relatively tiny Higgs signal. Experimental evidence indicates that the Higgs mass is relatively low, in which case it will decay predominantly to a b$\\bar{b}$ quark-antiquark pair. The daughter products that must be used to reconstruct the parent Higgs are therefore likely to be heavy flavour b-quark jets whose energies must be known as accurately as possible. In the first part of this thesis consideration is given to these jets, in particular to the jet energy resolution and dijet mass resolution that they could offer. One way of investigating the necessary tools for such a Higgs search is to study a very similar decay to that of a low-mass Higgs particle: a Z boson decaying to a b quark and an anti-b-quark. This signal, not previously observed at the Tevatron, offers an ideal testbed in which to

    In May 2002, the United States Department of Energy (DOE) signed Assistance Instrument Number DE-FC09-02CH11109 with the Medical University of South Carolina (MUSC) to support the Environmental Biosciences Program (EBP). This funding instrument replaces DOE Assistance Instrument Number DE-FC02-98CH10902. EBP is an integrated, multidisciplinary scientific research program, employing a range of research initiatives to identify, study and resolve environmental health risks. These initiatives are consistent with the MUSC role as a comprehensive state-supported health sciences institution and with the nation's need for new and better approaches to the solution of a complex and expansive array of environment-related health problems. The intrinsic capabilities of a comprehensive health sciences institution enable MUSC to be a national resource for the scientific investigation of environmental health issues. EBPs success as a nationally prominent research program is due, in part, to its ability to task-organize scientific expertise from multiple disciplines in addressing these complex problems. Current research projects have focused EBP talent and resources on providing the scientific basis for risk-based standards, risk-based decision making and the accelerated clean-up of widespread environmental hazards. These hazards include trichloroethylene and low-dose ionizing radiation. A project is also being conducted in the use of geographical information system technology to analyze population health risks related to environmental hazards as a tool for risk-based decision-making.

    The decay modes anti B{sub s} → π{sup 0}(ρ{sup 0})η{sup (')} are dominated by electroweak penguins that are small in the standard model. In this work we investigate the contributions to these penguins from a model with an additional U(1){sup '} gauge symmetry and show there effects on the branching ratios of anti B{sub s} → π{sup 0}(ρ{sup 0})η{sup (')}. In a scenario of the model, where Z{sup '} couplings to the left-handed quarks vanish, we show that the maximum enhancement occurs in the branching ratio of anti B{sub s}{sup 0} → π{sup 0}η{sup '} where it can reach 6 times the SM prediction. On the other hand, in a scenario of the model where Z{sup '} couplings to both left-handed and right-handed quarks do not vanish, we find that Z{sup '} contributions can enhance the branching ratio of B{sup 0}{sub s} → ρ{sup 0}η up to one order of magnitude comparing to the SM prediction for several sets of the parameter space where both ΔM{sub B{sub s}} and S{sub ψφ} constraints are satisfied. This kind of enhancement occurs for a rather fine-tuned point where the ΔM{sub B{sub s}} constraint on vertical stroke S{sub SM}(B{sub s}) + S{sub Z}{sup {sub '}} (B{sub s}) vertical stroke is fulfilled by overcompensating the SM via S{sub Z}{sup {sub '}}(B{sub s}) ≅ -2S{sub SM}(B{sub s}).

    In this thesis, the measurement of the inclusive cross section of the process Z+b anti b is measured where the Z can decay to an electron-positron pair or to a muon-antimuon pair. The analysed data was recorded by the ATLAS experiment in 2011 at a centre-of-mass energy of √(s)=7 TeV and includes 4.58 fb -1 of proton-proton collisions. The resulting cross sections are unfolded to particle level and compared to LO and NLO predictions from different Monte Carlo generators.

    For an electron-photon collider the complete tree-level cross sections of the reaction γe→νb anti bW are computed at center-of-mass energies between 0.5 and 2.0 TeV, for top masses of 160 to 200 GeV and Higgs masses between 80 and 140 GeV within the standard model. It is shown that most of the about 50% smaller. Multiperipheral background and interferences are small, respectively negligible, in the energy range studied. By convoluting the basic cross sections with an energy spectrum of the backscattered photon beam, and inserting linear collider luminosities as anticipated in present designs, realistic νb anti bW event rates are estimated. This results in large event rates for γe→νtb and γe→νHW. We estimate that the CKM matrix element vertical stroke V tb vertical stroke can be probed from the νtb final state to an accuracy of 1-3% at √ssub(e + e - )>or∼1 TeV. Assuming an effective Lagrangian based on dimension-6 operators we discuss the sensitivity for detecting deviations of the HWW coupling from the Standard Model in the reaction γe→νHW. (orig.)

    The discovery of the D{sup *}{sub s0}(2317) and D{sub s1}(2460) resonances in the charmed-strange meson spectra revealed that formerly successful constituent quark models lose predictability in the vicinity of two-meson thresholds. The emergence of non-negligible effects due to meson loops requires an explicit evaluation of the interplay between Q anti q and (Q anti q)(q anti q) Fock components. In contrast to the c anti s sector, there is no experimental evidence of J{sup P} = 0{sup +}, 1{sup +} bottom-strange states yet. Motivated by recent lattice studies, in this work the heavy-quark partners of the D{sub s0}{sup *}(2317) and D{sub s1}(2460) states are analyzed within a heavy meson chiral unitary scheme. As a novelty, the coupling between the constituent quark-model P-wave anti B{sub s} scalar and axial mesons and the anti B{sup (*)}K channels is incorporated employing an effective interaction, consistent with heavy-quark spin symmetry, constrained by the lattice energy levels.

    To review relevant literature that address the challenges of the biosciences in nurse education. More precisely the review aims to explore the literature, concerning students' learning, learning contexts and methodological issues and identify any significant gaps. Knowledge of anatomy, physiology and biochemistry are essential for the understanding of human beings and for full appreciation of the concepts of illness and disease. The current status would seem to be that the required competencies within bioscience subjects are difficult to acquire and students have high rates of failure. Integrative review. The research were performed on Cinahl, ERIC, Medline and British Nursing Index databases in a period from 2013 until 2017. Descriptive analytical methods were used for the initial research trawl. The search strategy resulted in 23 papers. The results of this review shed light on certain deficiencies in the research field looking at the biosciences in nurse education. There is a distinct lack of intervention studies, and thereby knowledge of how best to support students' learning in effective ways. Of note is that there are no field study approaches identified in the review sample. Many of the papers are single studies and course evaluations which may be seen as too narrow and inadequate a perspective. Students appear satisfied with the courses in the biosciences but there seems to be no correlation between satisfaction and achievement. This article is protected by copyright. All rights reserved.

    The cohort of students enrolled in the discipline-specific bioscience paper reflects a structural diversity in that it includes students of multiple ethnicities, varied age groups, differing scholastic and life experiences. These divergent identities of students are known to influence academic performance. The purpose of this retrospective quantitative study was to determine the ability of a set of variables such as age, gender, ethnicity, level of prior education, the place from which prior education was obtained, work experience and prior academic achievement to predict academic performance in the discipline-specific bioscience paper. The sample for this study was a purposive sample of all oral health students who had enrolled in the paper at the Auckland University of Technology from 2011 to 2014. The desensitised empirical data of 116 students from the University's database were subject to multivariable regression analysis. Pearson's correlation coefficients were calculated. Prior academic achievement was a statistically significant predictor variable (P academic performance in the discipline-specific bioscience paper and was also positively correlated (r = 0.641, P academic achievement was the only variable that was demonstrated to be correlated to and predictive of the academic performance in the discipline-specific bioscience paper. © 2016 John Wiley & Sons A/S.

  13. Automatic categorization of diverse experimental information in the bioscience literature

    Background Curation of information from bioscience literature into biological knowledge databases is a crucial way of capturing experimental information in a computable form. During the biocuration process, a critical first step is to identify from all published literature the papers that contain results for a specific data type the curator is interested in annotating. This step normally requires curators to manually examine many papers to ascertain which few contain information of interest and thus, is usually time consuming. We developed an automatic method for identifying papers containing these curation data types among a large pool of published scientific papers based on the machine learning method Support Vector Machine (SVM). This classification system is completely automatic and can be readily applied to diverse experimental data types. It has been in use in production for automatic categorization of 10 different experimental datatypes in the biocuration process at WormBase for the past two years and it is in the process of being adopted in the biocuration process at FlyBase and the Saccharomyces Genome Database (SGD). We anticipate that this method can be readily adopted by various databases in the biocuration community and thereby greatly reducing time spent on an otherwise laborious and demanding task. We also developed a simple, readily automated procedure to utilize training papers of similar data types from different bodies of literature such as C. elegans and D. melanogaster to identify papers with any of these data types for a single database. This approach has great significance because for some data types, especially those of low occurrence, a single corpus often does not have enough training papers to achieve satisfactory performance. Results We successfully tested the method on ten data types from WormBase, fifteen data types from FlyBase and three data types from Mouse Genomics Informatics (MGI).

    We present the results of a calculation of the perturbative QCD corrections for the semileptonic inclusive width of a heavy flavored meson. Within the Heavy Quark Expansion we analytically compute the QCD correction to the coefficient of power suppressed contribution of chromo-magnetic operator in the limit of vanishing mass of the final state quark. The important phenomenological applications are decays of bottom mesons, and to the less extent, charmed mesons.

  17. Predictions for the anti B0 → anti K*0 X(YZ) and anti Bs0 → φ X(YZ) with X(4160), Y(3940), Z(3930)

    We investigate the decay of anti B 0 → anti K *0 R and anti B s 0 → φR with R being the X(4160), Y(3940), Z(3930) resonances. Under the assumption that these states are dynamically generated from the vector-vector interaction, as has been concluded from several theoretical studies, we use a reaction mechanism of quark production at the elementary level, followed by hadronization of one final q anti q pair into two vectors and posterior final state interaction of this pair of vector mesons to produce the resonances. With this procedure we are able to predict five ratios for these decays, which are closely linked to the dynamical nature of these states, and also predict the order of magnitude of the branching ratios which we find of the order of 10 -4 , well within the present measurable range. In order to further test the dynamical nature of these resonances we study the anti B s 0 → φ D* anti D* and anti B s 0 → φ D s * anti D s * decays close to the D* anti D* and D s * anti D s * thresholds and make predictions for the ratio of the mass distributions in these decays and the anti B s 0 → φR decay widths. The measurement of these decays rates can help unravel the nature of these resonances. (orig.)

    The influence of strong and electroweak penguin amplitudes in B/ anti B→π + π - is investigated in connection with the determination of the unitarity triangle angle α of the CKM matrix. A relation between the observable asymmetry, the angle α, and the penguin amplitude is established. A model calculation of the penguin amplitude shows that the CP asymmetry in B 0 →π + π - decays is only mildly influenced by the penguin amplitudes. Experimental limits on pure penguin and penguin dominated processes are consistent with the model. This information also suggests in a rather model independent way that penguin amplitudes will not be a serious complicating factor in the determination of α from the π + π - time dependent asymmetry.

    The International Conference "BIOCOMP2012 - Mathematical Modeling and Computational Topics in Biosciences'', was held in Vietri sul Mare (Italy), June 4-8, 2012. It was dedicated to the Memory of Professor Luigi M. Ricciardi (1942-2011), who was a visionary and tireless promoter of the 3 previous editions of the BIOCOMP conference series. We thought that the best way to honor his memory was to continue the BIOCOMP program. Over the years, this conference promoted scientific activities related to his wide interests and scientific expertise, which ranged in various areas of applications of mathematics, probability and statistics to biosciences and cybernetics, also with emphasis on computational problems. We are pleased that many of his friends and colleagues, as well as many other scientists, were attracted by the goals of this recent event and offered to contribute to its success.

    The mission of the Division of Energy Biosciences is to support research that advances the fundamental knowledge necessary for the future development of biotechnologies related to the Department of Energy`s mission. The departmental civilian objectives include effective and efficient energy production, energy conservation, environmental restoration, and waste management. The Energy Biosciences program emphasizes research in the microbiological and plant sciences, as these understudied areas offer numerous scientific opportunities to dramatically influence environmentally sensible energy production and conservation. The research supported is focused on the basic mechanisms affecting plant productivity, conversion of biomass and other organic materials into fuels and chemicals by microbial systems, and the ability of biological systems to replace energy-intensive or pollutant-producing processes. The Division also addresses the increasing number of new opportunities arising at the interface of biology with other basic energy-related sciences such as biosynthesis of novel materials and the influence of soil organisms on geological processes.

  1. Search for the Standard Model Higgs boson produced in association with a pair of top quarks and decaying into a b anti b-pair in the single lepton channel at √(s) = 13 TeV with the ATLAS experiment at the LHC

    This thesis presents a search for Standard Model Higgs boson produced in association with top quark pairs, t anti tH. The analysis uses 13.2 fb{sup -1} of pp collision data at √(s)=13 TeV collected in 2015 and 2016 with the ATLAS detector at the LHC. The considered decay mode for the Higgs boson is H→ b anti b and the single lepton decay channel (electron or muon) for the t anti t pair. The sensitivity of this channel is improved by an event categorisation according to the jet multiplicity and the number of jets containing a b-hadron decay. Multivariate techniques are used to distinguish the signal events from the background events, which are dominated by t anti t+jets production, in particular by the t anti t+b anti b component. The data are found to be consistent with both the background-only hypothesis and with the Standard Model t anti tH prediction. The ratio of the measured t anti tH signal cross-section to the Standard Model expectation is found to be μ=1.6±1.1, assuming a Higgs boson mass of 125 GeV. No significant excess of events above the background expectation is found and an observed (expected) upper limit on μ of 3.6(2.2) is set at a 95% confidence level.

    To explore if active learning principles be applied to nursing bioscience assessments and will this influence student perception of confidence in applying theory to practice? A review of the literature utilising searches of various databases including CINAHL, PUBMED, Google Scholar and Mosby's Journal Index. The literature search identified research from twenty-six original articles, two electronic books, one published book and one conference proceedings paper. Bioscience has been identified as an area that nurses struggle to learn in tertiary institutions and then apply to clinical practice. A number of problems have been identified and explored that may contribute to this poor understanding and retention. University academics need to be knowledgeable of innovative teaching and assessing modalities that focus on enhancing student learning and address the integration issues associated with the theory practice gap. Increased bioscience education is associated with improved patient outcomes therefore by addressing this "bioscience problem" and improving the integration of bioscience in clinical practice there will subsequently be an improvement in health care outcomes. From the literature several themes were identified. First there are many problems with teaching nursing students bioscience education. These include class sizes, motivation, concentration, delivery mode, lecturer perspectives, student's previous knowledge, anxiety, and a lack of confidence. Among these influences the type of assessment employed by the educator has not been explored or identified as a contributor to student learning specifically in nursing bioscience instruction. Second that educating could be achieved more effectively if active learning principles were applied and the needs and expectations of the student were met. Lastly, assessment influences student retention and the student experience and as such assessment should be congruent with the subject content, align with the learning

  5. A novel flavour tagging algorithm using machine learning techniques and a precision measurement of the B0- anti B0 oscillation frequency at the LHCb experiment

    Kreplin, Katharina

    2015-01-01

    This thesis presents a novel flavour tagging algorithm using machine learning techniques and a precision measurement of the B 0 - anti B 0 oscillation frequency Δm d using semileptonic B 0 decays. The LHC Run I data set is used which corresponds to 3 fb -1 of data taken by the LHCb experiment at a center-of-mass energy of 7 TeV and 8 TeV. The performance of flavour tagging algorithms, exploiting the b anti b pair production and the b quark hadronization, is relatively low at the LHC due to the large amount of soft QCD background in inelastic proton-proton collisions. The standard approach is a cut-based selection of particles, whose charges are correlated to the production flavour of the B meson. The novel tagging algorithm classifies the particles using an artificial neural network (ANN). It assigns higher weights to particles, which are likely to be correlated to the b flavour. A second ANN combines the particles with the highest weights to derive the tagging decision. An increase of the opposite side kaon tagging performance of 50% and 30% is achieved on B + → J/ψK + data. The second number corresponds to a readjustment of the algorithm to the B 0 s production topology. This algorithm is employed in the precision measurement of Δm d . A data set of 3.2 x 10 6 semileptonic B 0 decays is analysed, where the B 0 decays into a D - (K + π - π - ) or D *- (π - anti D 0 (K + π - )) and a μ + ν μ pair. The ν μ is not reconstructed, therefore, the B 0 momentum needs to be statistically corrected for the missing momentum of the neutrino to compute the correct B 0 decay time. A result of Δm d =0.503±0.002(stat.)±0.001(syst.) ps -1 is obtained. This is the world's best measurement of this quantity.

    In this thesis, a systematic analysis of the anti B {yields} X{sub s}{gamma} photon spectrum in the endpoint region is presented. The endpoint region refers to a kinematic configuration of the final state, in which the photon has a large energy m{sub b}-2E{sub {gamma}}=O({lambda}{sub QCD}), while the jet has a large energy but small invariant mass. Using methods of soft-collinear effective theory and heavy-quark effective theory, it is shown that the spectrum can be factorized into hard, jet, and soft functions, each encoding the dynamics at a certain scale. The relevant scales in the endpoint region are the heavy-quark mass m{sub b}, the hadronic energy scale {lambda}{sub QCD} and an intermediate scale {radical}({lambda}{sub QCD}m{sub b}) associated with the invariant mass of the jet. It is found that the factorization formula contains two different types of contributions, distinguishable by the space-time structure of the underlying diagrams. On the one hand, there are the direct photon contributions which correspond to diagrams with the photon emitted directly from the weak vertex. The resolved photon contributions on the other hand arise at O(1/m{sub b}) whenever the photon couples to light partons. In this work, these contributions are explicitly defined in terms of convolutions of jet functions with subleading shape functions. While the direct photon contributions can be expressed in terms of a local operator product expansion, when the photon spectrum is integrated over a range larger than the endpoint region, the resolved photon contributions always remain non-local. Thus, they are responsible for a non-perturbative uncertainty on the partonic predictions. In this thesis, the effect of these uncertainties is estimated in two different phenomenological contexts. First, the hadronic uncertainties in the anti B {yields} X{sub s}{gamma} branching fraction, defined with a cut E{sub {gamma}} > 1.6GeV are discussed. It is found, that the resolved photon

    The mission of the Division of Energy Biosciences is to support research that advances the fundamental knowledge necessary for the future development of biotechnologies related to the Department of Energy`s mission. The departmental civilian objectives include effective and efficient energy production, energy conservation, environmental restoration, and waste management. The Energy Biosciences program emphasizes research in the microbiological and plant sciences, as these understudied areas offer numerous scientific opportunities to dramatically influence environmentally sensible energy production and conservation. The research supported is focused on the basic mechanism affecting plant productivity, conversion of biomass and other organic materials into fuels and chemicals by microbial systems, and the ability of biological systems to replace energy-intensive or pollutant-producing processes. The Division also addresses the increasing number of new opportunities arising at the interface of biology with other basic energy-related sciences such as biosynthesis of novel materials and the influence of soil organisms on geological processes. This report gives summaries on 225 projects on photosynthesis, membrane or ion transport, plant metabolism and biosynthesis, carbohydrate metabolism lipid metabolism, plant growth and development, plant genetic regulation and genetic mechanisms, plant cell wall development, lignin-polysaccharide breakdown, nitrogen fixation and plant-microbial symbiosis, mechanism for plant adaptation, fermentative microbial metabolism, one and two carbon microbial metabolism, extremophilic microbes, microbial respiration, nutrition and metal metabolism, and materials biosynthesis.

  8. Ontologies and standards in bioscience research: for machine or for human

    Full Text Available Ontologies and standards are very important parts of today’s bioscience research. With the rapid increase of biological knowledge, they provide mechanisms to better store and represent data in a controlled and structured way, so that scientists can share the data, and utilize a wide variety of software and tools to manage and analyze the data. Most of these standards are initially designed for computers to access large amounts of data that are difficult for human biologists to handle, and it is important to keep in mind that ultimately biologists are going to produce and interpret the data. While ontologies and standards must follow strict semantic rules that may not be familiar to biologists, effort must be spent to lower the learning barrier by involving biologists in the process of development, and by providing software and tool support. A standard will not succeed without support from the wider bioscience research community. Thus, it is crucial that these standards be designed not only for machines to read, but also to be scientifically accurate and intuitive to human biologists.

    With a combined analysis of data on Υ(5S) → h b (1P, 2P)π + π - and Υ(5S) → B (*) anti B (*) π in an effective field theory approach, we determine resonance parameters of Z b states in two scenarios. In one scenario we assume that Z b states are pure molecular states, while in the other one we assume that Z b states contain compact components. We find that the present data favor that there should be some compact components inside Z b (') associated with themolecular components. By fitting the invariant mass spectra of Υ(5S) → h b (1P, 2P)π + π - and Υ(5S) → B (*) anti B * π, we determine that the probability of finding the compact components in Z b states may be as large as about 40 %.

    Low-dose and low-dose-rate radiation effects on life-span, pathological changes, hemopoiesis and cytokine production in experimental animals have been investigated in our laboratory. In the intermediate period of the investigation, an expert committee on radiation biology, which was composed of two task groups, was organized. The purposes of the committee were to assess of previous studies and plan future research for Advanced Molecular Bio-Sciences Research Center (AMBIC). In its report, the committee emphasized the necessity of molecular research in radiation biology and ecology, and proposed six subjects for the research: 1) Molecular carcinogenesis of low-dose radiation; 2) Radiation effects on the immune system and hemopoietic system; 3) Molecular mechanisms of hereditary effect; 4) Non cancer effect of low-dose radiation; 5) Gene targeting for ion transport system in plants; 6) Bioremediation with transgenic plant and bacteria. Exploration of the AMBIC project will continue under the committee's direction. (author)

    Biomedical researchers often have to work on massive, detailed, and heterogeneous datasets that raise new challenges of information management. This study reports an investigation into the nature of the problems faced by the researchers in two bioscience test laboratories when dealing with their data management applications. Data were collected using ethnographic observations, questionnaires, and semi-structured interviews. The major problems identified in working with these systems were related to data organization, publications, and collaboration. The interoperability standards were analyzed using a C4I framework at the level of connection, communication, consolidation, and collaboration. Such an analysis was found to be useful in judging the capabilities of data management systems at different levels of technological competency. While collaboration and system interoperability are the “must have” attributes of these biomedical scientific laboratory information management applications, usability and human interoperability are the other design concerns that must also be addressed for easy use and implementation.

    2013-06-01

    This manuscript describes a pilot study in ethics education employing a problem-based learning approach to the study of novel, complex, ethically fraught, unavoidably public, and unavoidably divisive policy problems, called "fractious problems," in bioscience and biotechnology. Diverse graduate and professional students from four US institutions and disciplines spanning science, engineering, humanities, social science, law, and medicine analyzed fractious problems employing "navigational skills" tailored to the distinctive features of these problems. The students presented their results to policymakers, stakeholders, experts, and members of the public. This approach may provide a model for educating future bioscientists and bioengineers so that they can meaningfully contribute to the social understanding and resolution of challenging policy problems generated by their work.

    The essay is an empirical case study of famed British scientist Francis Crick. Viewing him as a 'cross-worlds influencer' who was moreover dedicated to a cause, I have tried to understand how these two characteristics influenced the trajectory of his long career and how they shaped his contributions to the diverse research fields in which he was active, and concluded that these characteristics reconfigure Crick's career into a coherent whole. First, I identify a major thread running through Crick's career: helping organise 'un-disciplined' new research fields, and show that his successive choices were not serendipitous but motivated by what he construed as a crusade against 'vitalism': anti-vitalism was a defining driver of his career. I then examine how Crick put his skills as a crossworlds influencer to the service of his cause, by helping organise his chosen fields of intervention. I argue that his activities as a cross-worlds influencer were an integral part of his way of 'doing science' and that his contributions to science, neuroscience in particular, should be re-evaluated in this light. This leads me to advance a possible strategy for historians to investigate big bioscience fields. Following Abir-Am, I propose to trace their genealogies back to the fluctuating semi-institutional gatherings and the institutional structures that sustained them. My research on Crick supports the view that such studies can bring insights into the question of why the contours of contemporary big bioscience endeavours have come to be shaped the way they are. Further, the essay provides a heuristic device for approaching these enquiries: 'follow the cross-worlds influencers' who worked to build and organise these semi-institutional gatherings and institutional structures.

    In this thesis, a search for the H →b anti b decay mode of the Standard Model Higgs boson in associated production with a vector boson is presented. The search is based on the entire data-set recorded by the ATLAS experiment in 2012 amounting to 20.3 fb{sup -1} of data. A novel search strategy based on a machine learning approach using boosted decision trees and a variable set constructed from Lorentz invariant quantities is introduced. No significant excess above the Standard Model background expectation is observed. For a Higgs boson mass of m{sub H}=125 GeV, the expected upper limit on the Higgs boson production cross section assuming the absence of signal is 2.06 x σ{sub SM}, while the observed limit is 3.15 x σ{sub SM}. This excess corresponds to a local significance of 1.1 standard deviations. The ratio of the measured signal strength to the Standard Model expectation is μ=1.40±0.95.

    We present a theoretical analysis of the process panti p → μ ± μ ± X, μ ± X', μ + μ - X' due to heavy flavour production and decays, based on perturbative quantum chromodynamics, QCD. We find reasonable agreement for the inclusive rates and distributions between the UA1 measurement and our calculations, with the exception of the dimuon ratio R(±±/+--), which is found typically a factor ≅ 1.8 smaller than the UA1 data. We interpret this excess in terms of B s 0 -anti B s 0 mixing and obtain a lower bound on the mixing probability, ρ s > 0.14. In the standard model this implies a lower bound on the Cabibbo-Kobayashi-Maskawa matrix element vertical strokeV ts vertical stroke given the top quark mass. The lower bound on vertical strokeV ts vertical stroke and the upper bound on vertical strokeV td vertical stroke, obtained from the (upper bound) B d 0 -anti B d 0 mixing probability, ρ d , from e + e - experiments are worked out.

    As a component of the Department of Energy, the Energy Biosciences (EB) program of the Office of Basic Energy Sciences supports long-term research aimed at addressing energy-related problems utilizing biological systems. There are three main components of the EB program. The first, Primary Biological Energy Conversion, concentrates on research on plant and microbial photosynthesis, but also deals with plant growth control, stress reactions, and interaction with pathogens. The second, Bioconversion of Products, concentrates on utilization of the products of primary energy conversion. Specific examples include biosynthesis of potential fuels or chemicals, biodegradation of lignocellulose into potentially useful compounds, plant/microbe symbiosis, microbial methanogenesis and fermentation. The third main component of the EB program involves providing the basic research infrastructure to support future discoveries. The emphasis here is on investigation of basic genetic mechanisms, both in novel systems and extensively studied systems such as maize; development of critical databases, techniques, and instrumentation; and support of training in areas that are important but underpopulated.

    Full Text Available In contrast to the narrowing of options in academic careers, the bioscience industry offers robust employment opportunities for STEM-trained workers, especially those who display both scientific and business talent. Unfortunately, traditional science programs typically lack curricular features that develop this type of worker. The North Carolina State University Master of Microbial Biotechnology (MMB program facilitates industry-specific experiential learning to fill this training gap. Similar programs often rely on a single industry internship to provide students relevant work experience, but completion of one internship might not suffice to position students for employment in a highly competitive job market. The MMB program requires students to complete an internship and three practicum projects in an industry setting, to promote development of key skills in a variety of areas, to build confidence in the ability to perform initial job duties, and to establish a more extensive work history in industry. In this Perspective we discuss an unmet need in undergraduate and graduate STEM education that can be filled by incorporating a similar set of industry-specific work experiences for students who desire to transition from academe into the life science industry.

    Full Text Available Abstract Background Next generation sequencing (NGS technology has revolutionized genomic and genetic research. The pace of change in this area is rapid with three major new sequencing platforms having been released in 2011: Ion Torrent’s PGM, Pacific Biosciences’ RS and the Illumina MiSeq. Here we compare the results obtained with those platforms to the performance of the Illumina HiSeq, the current market leader. In order to compare these platforms, and get sufficient coverage depth to allow meaningful analysis, we have sequenced a set of 4 microbial genomes with mean GC content ranging from 19.3 to 67.7%. Together, these represent a comprehensive range of genome content. Here we report our analysis of that sequence data in terms of coverage distribution, bias, GC distribution, variant detection and accuracy. Results Sequence generated by Ion Torrent, MiSeq and Pacific Biosciences technologies displays near perfect coverage behaviour on GC-rich, neutral and moderately AT-rich genomes, but a profound bias was observed upon sequencing the extremely AT-rich genome of Plasmodium falciparum on the PGM, resulting in no coverage for approximately 30% of the genome. We analysed the ability to call variants from each platform and found that we could call slightly more variants from Ion Torrent data compared to MiSeq data, but at the expense of a higher false positive rate. Variant calling from Pacific Biosciences data was possible but higher coverage depth was required. Context specific errors were observed in both PGM and MiSeq data, but not in that from the Pacific Biosciences platform. Conclusions All three fast turnaround sequencers evaluated here were able to generate usable sequence. However there are key differences between the quality of that data and the applications it will support.

    The demand for equality of recognition or respect is the dominant passion of modernity. The 20th century experienced a giant leap in technological inventiveness and ruthless use of technological power. In the 21st century, human welfare and environmental wellbeing demand fundamental political appraisal. We have the means, if we choose, to eradicate poverty and to responsibly protect the global environment. However, economic, political and cultural systems act to differentially allocate the benefits and risks for growth between socioeconomic groups. For example, it is a matter of pride that the neonatal mortality rate in affluent societies has dropped substantially since the late 1970s. However, the level of infant mortality (three times the national average) and low birthweight (13%) among the Indigenous Australian population is the highest in the country. With hindsight we now know that is the inevitable legacy of Australia's colonial history. Chronic physical and psychological stress is recognized as an important etiological factor in many lifestyle diseases of the cardiovascular, immune and reproductive systems. Diseases of adaptation are further advanced by non-adaptive lifestyle choices, depression, alcoholism and other drug dependencies. This review describes the principles of bioscience ethics and targets equity issues as they affect human reproduction across generations with particular reference to the Indigenous population of Australia. The review also considers ways we may advance global and cultural maturity from the Indigenous Australian perspective and proposes an ecologically based model of preventative care. If we are to embrace fundamental social change and protect future children without threatening parents' basic freedoms, then new beliefs and priorities--based on a compassionate understanding of biological systems--must evolve from the general public. Belief in human rights arising from a sense of human dignity is a collective outcome originating

    Deregulation is haltingly changing the United States electricity markets. The resulting uncertainty and/or rising energy costs can be hedged by generating electricity on-site and other benefits, such as use of otherwise wasted heat, can be captured. The Public Utility Regulatory Policy Act (PURPA) of 1978 first invited relatively small-scale generators ({ge} 1 MW) into the electricity market. The advent of efficient and reliable small scale and renewable equipment has spurred an industry that has, in recent years, made even smaller (business scale) electricity generation an economically viable option for some consumers. On-site energy capture and/or conversion, known as distributed energy resources (DER), offers consumers many benefits, such as economic savings and price predictability, improved reliability, control over power quality, and emissions reductions. Despite these benefits, DER adoption can be a daunting move to a customer accustomed to simply paying a monthly utility bill. San Diego is in many ways an attractive location for DER development: It has high electricity prices typical of California and a moderate climate i.e. energy loads are consistent throughout the year. Additionally, the price shock to San Diego Gas and Electric (SDG&E) customers during the summer of 2000 has interested many in alternatives to electricity price vulnerability. This report examines the business case for DER at the San Diego biotechnology supply company, BD Biosciences Pharmingen, which considered DER for a building with 200-300 kW base-load, much of which accommodates the refrigerators required to maintain chemicals. Because of the Mediterranean climate of the San Diego area and the high rate of air changes required due to on-site use of chemicals, modest space heating is required throughout the year. Employees work in the building during normal weekday business hours, and daily peak loads are typically about 500 kW.

  7. Harnessing the power of communities: career networking strategies for bioscience PhD students and postdoctoral researchers.

    With an ever more competitive global labour market, coupled with an ever-increasing population of PhD-qualified graduates, the ability to communicate effectively and build strategic connections with others can be advantageous in the job-search process. Whether in pursuit of a tenure-track or non-academic position, many postdoctoral researchers and PhD students will benefit from networking as early as possible to enhance their career prospects. Sometimes viewed cynically as 'using people' or dismissed as 'the old boy network,' the ability to make meaningful connections and build relationships can be more valuable than other job-related skills in order to gain entry to, and progress within, many professions. This mini-review highlights the positive influence of networking and how bioscience PhD students and postdoctoral researchers can harness the power of communities to achieve career success. It is argued that those who make connections and promote personal patronage through networking can gain an advantage over their contemporaries. A summary of key theories and research studies that underpin the practice of networking provides credence to these assertions, which are further substantiated with examples pertinent to the academic community. Although primarily focussed on the biosciences, much of the content is applicable to other scientists at a similar career stage.

  9. A novel flavour tagging algorithm using machine learning techniques and a precision measurement of the B{sup 0}- anti B{sup 0} oscillation frequency at the LHCb experiment

    2015-06-10

    This thesis presents a novel flavour tagging algorithm using machine learning techniques and a precision measurement of the B{sup 0}- anti B{sup 0} oscillation frequency Δm{sub d} using semileptonic B{sup 0} decays. The LHC Run I data set is used which corresponds to 3 fb{sup -1} of data taken by the LHCb experiment at a center-of-mass energy of 7 TeV and 8 TeV. The performance of flavour tagging algorithms, exploiting the b anti b pair production and the b quark hadronization, is relatively low at the LHC due to the large amount of soft QCD background in inelastic proton-proton collisions. The standard approach is a cut-based selection of particles, whose charges are correlated to the production flavour of the B meson. The novel tagging algorithm classifies the particles using an artificial neural network (ANN). It assigns higher weights to particles, which are likely to be correlated to the b flavour. A second ANN combines the particles with the highest weights to derive the tagging decision. An increase of the opposite side kaon tagging performance of 50% and 30% is achieved on B{sup +} → J/ψK{sup +} data. The second number corresponds to a readjustment of the algorithm to the B{sup 0}{sub s} production topology. This algorithm is employed in the precision measurement of Δm{sub d}. A data set of 3.2 x 10{sup 6} semileptonic B{sup 0} decays is analysed, where the B{sup 0} decays into a D{sup -}(K{sup +}π{sup -}π{sup -}) or D{sup *-} (π{sup -} anti D{sup 0}(K{sup +} π{sup -})) and a μ{sup +}ν{sub μ} pair. The ν{sub μ} is not reconstructed, therefore, the B{sup 0} momentum needs to be statistically corrected for the missing momentum of the neutrino to compute the correct B{sup 0} decay time. A result of Δm{sub d}=0.503±0.002(stat.)±0.001(syst.) ps{sup -1} is obtained. This is the world's best measurement of this quantity.

    1999-10-01

    Microsystems increasingly require precision deep microstructures that can be cost-effectively designed and manufactured. New products must be able to meet the demands of the rapidly growing markets for microfluidic, micro- optical and micromechanical devices in industrial sectors which include chemicals, pharmaceuticals, biosciences, medicine and food. The realization of such products, first requires an effective process to design and manufacture prototypes. Two process methods used for the fabrication of high aspect-ratio microstructures are based on X-ray beam lithography with electroforming processes and direct micromachining with a frequency multiplied Nd:YAG laser using nanosecond pulse widths. Factors which limit the efficiency and precision obtainable using such processes are important parameters when deciding on the best fabrication method to use. A basic microstructure with narrow channels suitable for a microfluidic mixer have been fabricated using both these techniques and comparisons made of the limitations and suitability of the processes in respect of fast prototyping and manufacture or working devices.

  11. Reflective writing as a tool for assessing teamwork in bioscience: insights into student performance and understanding of teamwork.

    To ensure a modern bioscience curriculum that responds to the current needs of stakeholders, there is a need to embed a range of generic capabilities that enables graduates to succeed in and contribute to a rapidly changing world, as well as building strong bioscience skills and knowledge. The curriculum must also prepare students for a rapidly evolving competitive work place and align with the needs of industry. This creates a challenge, how do we develop generic capabilities without losing discipline content. This report analyses teamwork projects embedded in an undergraduate Biotechnology degree designed to promote teamwork skills along with a deeper understanding of the underpinning biochemistry. Student reflective writing was used to capture students' understanding and experience of teamwork as well as provide insight into their metacognition. The analysis demonstrates that 73% of Year 3 and 93% of Year 4 students were capable of learning about teamwork through reflective writing. While the importance of frequent high quality communication was a common theme, evidence suggests that many students were unsophisticated in their use of communication software. The analysis also highlighted the depth of metacognition that underpins successful team function and the significant weaknesses in self-insight some students possess. These findings challenge assumptions regarding student capacity for leadership and the ability of some students to contribute to successful team outcomes. It is essential for the design of teamwork experiences to fully understand the competencies that underlie teamwork, the metacognitive processes required, and ensure that assessments are fair and measure individual academic performance.

    The current that flows between the electrical test equipment and the nuclear explosive must be limited to safe levels during electrical tests conducted on nuclear explosives at the DOE Pantex facility. The safest way to limit the current is to use batteries that can provide only acceptably low current into a short circuit; unfortunately this is not always possible. When it is not possible, current limiters, along with other design features, are used to limit the current. Three types of current limiters, the fuse blower, the resistor limiter, and the MOSFET-pass-transistor limiters, are used extensively in Pantex test equipment. Detailed failure mode and effects analyses were conducted on these limiters. Two other types of limiters were also analyzed. It was found that there is no best type of limiter that should be used in all applications. The fuse blower has advantages when many circuits must be monitored, a low insertion voltage drop is important, and size and weight must be kept low. However, this limiter has many failure modes that can lead to the loss of over current protection. The resistor limiter is simple and inexpensive, but is normally usable only on circuits for which the nominal current is less than a few tens of milliamperes. The MOSFET limiter can be used on high current circuits, but it has a number of single point failure modes that can lead to a loss of protective action. Because bad component placement or poor wire routing can defeat any limiter, placement and routing must be designed carefully and documented thoroughly.

    With thirteen beam induced quenches and numerous Machine Development tests, the current knowledge of LHC magnets quench limits still contains a lot of unknowns. Various approaches to determine the quench limits are reviewed and results of the tests are presented. Attempt to reconstruct a coherent picture emerging from these results is taken. The available methods of computation of the quench levels are presented together with dedicated particle shower simulations which are necessary to understand the tests. The future experiments, needed to reach better understanding of quench limits as well as limits for the machine operation are investigated. The possible strategies to set BLM (Beam Loss Monitor) thresholds are discussed. (author)

    2012-01-01

    Inverse limits provide a powerful tool for constructing complicated spaces from simple ones. They also turn the study of a dynamical system consisting of a space and a self-map into a study of a (likely more complicated) space and a self-homeomorphism. In four chapters along with an appendix containing background material the authors develop the theory of inverse limits. The book begins with an introduction through inverse limits on [0,1] before moving to a general treatment of the subject. Special topics in continuum theory complete the book. Although it is not a book on dynamics, the influen

    We believe that the professional responsibility of bioscience and biotechnology professionals includes a social responsibility to contribute to the resolution of ethically fraught policy problems generated by their work. It follows that educators have a professional responsibility to prepare future professionals to discharge this responsibility. This essay discusses two pilot projects in ethics pedagogy focused on particularly challenging policy problems, which we call "fractious problems". The projects aimed to advance future professionals' acquisition of "fractious problem navigational" skills, a set of skills designed to enable broad and deep understanding of fractious problems and the design of good policy resolutions for them. A secondary objective was to enhance future professionals' motivation to apply these skills to help their communities resolve these problems. The projects employed "problem based learning" courses to advance these learning objectives. A new assessment instrument, "Skills for Science/Engineering Ethics Test" (SkillSET), was designed and administered to measure the success of the courses in doing so. This essay first discusses the rationale for the pilot projects, and then describes the design of the pilot courses and presents the results of our assessment using SkillSET in the first pilot project and the revised SkillSET 2.0 in the second pilot project. The essay concludes with discussion of observations and results.

    The 55th Annual Canadian Society for Molecular Biosciences Conference on Epigenetics and Genomic Stability in Whistler, Canada, 14-18 March 2012, brought together 31 speakers from different nationalities. The organizing committee, led by Jim Davie (Chair) at the University of Manitoba (Manitoba, Canada), consisted of several established researchers in the fields of chromatin and epigenetics from across Canada. The meeting was centered on the contribution of epigenetics to gene expression, DNA damage and repair, and the role of environmental factors. A few interesting talks on replication added some insightful information on the controversial issue of histone post-translational modifications as genuine epigenetic marks that are inherited through cell division.

    With a combined analysis of data on Υ(5S) → h{sub b}(1P, 2P)π{sup +}π{sup -} and Υ(5S) → B{sup (*)} anti B{sup (*)}π in an effective field theory approach, we determine resonance parameters of Z{sub b} states in two scenarios. In one scenario we assume that Z{sub b} states are pure molecular states, while in the other one we assume that Z{sub b} states contain compact components. We find that the present data favor that there should be some compact components inside Z{sub b}{sup (')} associated with themolecular components. By fitting the invariant mass spectra of Υ(5S) → h{sub b}(1P, 2P)π{sup +}π{sup -} and Υ(5S) → B{sup (*)} anti B{sup *}π, we determine that the probability of finding the compact components in Z{sub b} states may be as large as about 40 %.

    Local analysis of trajectories of dynamical systems near an attractive periodic orbit displays the notion of asymptotic phase and isochrons. These notions are quite useful in applications to biosciences. In this note, we give an expression for the first approximation of equations of isochrons in the setting of perturbations of polynomial Hamiltonian systems. This method can be generalized to perturbations of systems that have a polynomial integral factor (like the Lotka-Volterra equation).

  6. Interactive problem-solving sessions in an introductory bioscience course engaged students and gave them feedback, but did not increase their exam scores.

    Active learning, including the promotion of student interactivity in lectures, has been found to improve student engagement and performance in university science classes. This letter describes the use of Pearson's Learning Catalytics to run regular, formatively assessed problem-solving sessions as part of the semiflipped redesign of an introductory level university bioscience course. Students found the problem-solving sessions more engaging than a traditional lecture, and felt that they were receiving better feedback on their progress in the course. Their participation in the problem-solving sessions was strongly associated with their performance in the course's summative assessments, making it possible to identify and assist probable poor performers early in the course. Other measures of student engagement with the course were not improved, and neither were their average exam grades when compared with their grades in a course which had not been redesigned. Possible reasons for this are discussed. © FEMS 2017. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.

    2007-01-01

    Structural mapping of proteins and nucleic acids with high resolution in solution is of critical importance for understanding their biological function. A wide range of footprinting technologies have been developed over the last ten years to address this need. Beamline X28C, a white-beam X-ray source at the National Synchrotron Light Source of Brookhaven National Laboratory, functions as a platform for synchrotron footprinting research and further technology development in this growing field. An expanding set of user groups utilize this national resource funded by the National Institute of Biomedical Imaging and Bioengineering of the National Institutes of Health. The facility is operated by the Center for Synchrotron Biosciences and the Center for Proteomics of Case Western Reserve University. The facility includes instrumentation suitable for conducting both steady-state and millisecond time-resolved footprinting experiments based on the production of hydroxyl radicals by X-rays. Footprinting studies of nucleic acids are routinely conducted with X-ray exposures of tens of milliseconds, which include studies of nucleic acid folding and their interactions with proteins. This technology can also be used to study protein structure and dynamics in solution as well as protein-protein interactions in large macromolecular complexes. This article provides an overview of the X28C beamline technology and defines protocols for its adoption at other synchrotron facilities. Lastly, several examples of published results provide illustrations of the kinds of experiments likely to be successful using these approaches

    An indispensable part of our personal and working lives, computing has also become essential to industries and governments. Steady improvements in computer hardware have been supported by periodic doubling of transistor densities in integrated circuits over the past fifty years. Such Moore scaling now requires ever-increasing efforts, stimulating research in alternative hardware and stirring controversy. To help evaluate emerging technologies and increase our understanding of integrated-circuit scaling, here I review fundamental limits to computation in the areas of manufacturing, energy, physical space, design and verification effort, and algorithms. To outline what is achievable in principle and in practice, I recapitulate how some limits were circumvented, and compare loose and tight limits. Engineering difficulties encountered by emerging technologies may indicate yet unknown limits.

Active instrumentation, such as the Beam Current Limiter, is a component of the RSS. The current limiter is designed to limit the average current in a beam line below a specific level, thus minimizing the maximum current available for a beam spill accident. The beam current limiter is a self-contained, electrically isolated toroidal beam transformer which continuously monitors beam current. It is designed as fail-safe instrumentation. The design philosophy, hardware design, operation, and limitations of the device are described

  14. JET pump limiter

    1988-01-01

    JET plans to install two pump limiter modules which can be used for belt-limiter, inner-wall and X-point discharges and, also, for 1-2s as the main limiter. A design is presented which is compatible with two diagnostic systems, and which allows partial removal of the pump limiter to provide access for remote-handling operations. The high heat-flux components are initially cooled during a pulse. Heat is removed between discharges by radiation and pressure contacts to a water-cooled support structure. The pumping edge will be made of annealed pyrolytic graphite. Exhaust efficiency has been estimated, for a 1-d edge model, using a Monte-Carlo calculation of neutral gas transport. When the pump limiter is operated together with other wall components we expect an efficiency of ≅ 5% (2.5 x 10 21 part/s). As a main limiter the efficiency increases to about 10%. (author)

The design of limitations is based on very large activities in the computational field but mostly on the high level of the plant-wide own commissioning experience of a turnkey contractor. Limitations combine intelligence features of closed-loop controls with the high availability of protection systems. (orig.)

    Every detector has limitations in terms of solid angle, particular technologies chosen, cracks due to mechanical structure, etc. If all of the presently planned parts of STAR [Solenoidal Tracker At RHIC] were in place, these factors would not seriously limit our ability to exploit the spin physics possible in RHIC. What is of greater concern at the moment is the construction schedule for components such as the Electromagnetic Calorimeters, and the limited funding for various levels of triggers.

The beam--beam tune shift limitation at 0.005 can be avoided, and a computer simulation seems to show 0.005 is a pessimistic limit. For beams of reasonable smoothness on the edge, the actual limit should be somewhat higher. Some coupling effects due to the beam--beam interaction are also examined

  1. Advanced limiters for ISX

    International Nuclear Information System (INIS)

    Mioduszewski, P.K.; Edmonds, P.H.; Sheffield, J.

    1982-01-01

    Continuous removal of heat and particles becomes a vital necessity in future steady-state fusion devices. The pump limiter seems to be an attractive concept to combine these two tasks. On ISX, various schemes of pump limiters are being explored with the final goal to furnish the ISX--C device with a pump limiter to handle heat removal and particle control in steady state. The emphasis of the present paper is on pump limiters based on ballistic particle collection. If this concept turns out to be successful in supplying sufficient pumping efficiency, it may be possible to design pump limiters without a leading edge. Analytical calculations of the particle collection efficiency are given for various limiter configurations. Pumping efficiencies of approximately 4--10%, depending on the specific configuration, seem to be feasible and should be sufficient for steady-state operation. Initial experimental results on pump limiter studies in ISX--B confirm the calculated collection efficiencies. By measuring the ion saturation current to the limiter blade and the pressure buildup simultaneously, we found a correlation between the incident particle flux and the pressure rise that agrees well with a simple model

  3. Mitigating greenhouse: Limited time, limited options

    International Nuclear Information System (INIS)

    Moriarty, Patrick; Honnery, Damon

    2008-01-01

    Most human-caused climate change comes from fossil fuel combustion emissions. To avoid the risk of serious climate change, very recent research suggests that emission reductions will need to be both large and rapidly implemented. We argue that technical solutions-improving energy efficiency, use of renewable and nuclear energy, and carbon capture and sequestration-can only be of minor importance, mainly given the limited time available to take effective climate action. Only curbing energy use, perhaps through 'social efficiency' gains, particularly in the high-energy consumption countries, can provide the rapid emissions reductions needed. The social efficiency approach requires a basic rethinking in how we can satisfy our human needs with low environmental impacts. Large cuts in emissions could then occur rapidly, but only if resistance to such changes can be overcome. Particularly in transport, there are also serious potential conflicts between the technical and the social efficiency approaches, requiring a choice to be made

    Directory of Open Access Journals (Sweden)

    Oleg Svatos

    2013-01-01

    Full Text Available In this paper we analyze complexity of time limits we can find especially in regulated processes of public administration. First we review the most popular process modeling languages. There is defined an example scenario based on the current Czech legislature which is then captured in discussed process modeling languages. Analysis shows that the contemporary process modeling languages support capturing of the time limit only partially. This causes troubles to analysts and unnecessary complexity of the models. Upon unsatisfying results of the contemporary process modeling languages we analyze the complexity of the time limits in greater detail and outline lifecycles of a time limit using the multiple dynamic generalizations pattern. As an alternative to the popular process modeling languages there is presented PSD process modeling language, which supports the defined lifecycles of a time limit natively and therefore allows keeping the models simple and easy to understand.

    1983-06-01

    The concept of the limiter-divertor proposed by Mirnov is extended to a toroidal limiter-divertor (which we call moving toroidal limiter) using the stream of ferromagnetic balls coated with a low Z materials such as plastics, graphite and ceramics. An important advantage of the use of the ferromagnetic materials would be possible soft landing of the balls on a catcher, provided that the temperature of the balls is below Curie point. Moreover, moving toroidal limiter would work as a protector of the first wall not only against the vertical movement of plasma ring but also against the violent inward motion driven by major disruption because the orbit of the ball in the case of moving toroidal limiter distributes over the small major radius side of the toroidal plasma.

    Conn, R.W.

    1984-05-01

    Recent experiments with a scoop limiter without active internal pumping have been carried out in the PDX tokamak with up to 6MW of auxiliary neutral beam heating. Experiments have also been done with a rotating head pump limiter in the PLT tokamak in conjunction with RF plasma heating. Extensive experiments have been done in the ISX-B tokamak and first experiments have been completed with the ALT-I limiter in TEXTOR. The pump limiter modules in these latter two machines have internal getter pumping. Experiments in ISX-B are with ohmic and auxiliary neutral beam heating. The results in ISX-B and TEXTOR show that active density control and particle removal is achieved with pump limiters. In ISX-B, the boundary layer (or scape-off layer) plasma partially screens the core plasma from gas injection. In both ISX-B and TEXTOR, the pressure internal to the module scales linearly with plasma density but in ISX-B, with neutral beam injection, a nonlinear increase is observed at the highest densities studied. Plasma plugging is the suspected cause. Results from PDX suggest that a region may exist in which core plasma energy confinement improves using a pump limiter during neutral beam injection. Asymmetric radial profiles and an increased edge electron temperature are observed in discharges with improved confinement. The injection of small amounts of neon into ISX-B has more clearly shown an improved electron core energy confinement during neutral beam injection. While carried out with a regular limiter, this Z-mode of operation is ideal for use with pump limiters and should be a way to achieve energy confinement times similar to values for H-mode tokamak plasmas. The implication of all these results for the design of a reactor pump limiter is described

    The use of limiter pumps as the principle plasma exhaust system of a magnetic confinement fusion device promises significant simplification, when compared to previously investigating divertor based systems. Further simplifications, such as the integration of the exhaust system with a radio frequency heating system and with the main reactor shield and structure are investigated below. The integrity of limiters in a reactor environment is threatened by many mechanisms, the most severe of which may be erosion by sputtering. Two novel topolgies are suggested which allow high erosion without limiter failure

The integrity of limiters in a reactor environment is threatened by many mechanisms, the most severe of which may be erosion by sputtering. Two novel topologies are suggested which allow high erosion without limiter failure

  17. Limit lines for risk

    Approaches to the regulation of risk from technological systems, such as nuclear power plants or chemical process plants, in which potential accidents may result in a broad range of adverse consequences must take into account several different aspects of risk. These include overall or average risk, accidents posing high relative risks, the rate at which accident probability decreases with increasing accident consequences, and the impact of high frequency, low consequence accidents. A hypothetical complementary cumulative distribution function (CCDF), with appropriately chosen parametric form, meets all these requirements. The Farmer limit line, by contrast, places limits on the risks due to individual accident sequences, and cannot adequately account for overall risk. This reduces its usefulness as a regulatory tool. In practice, the CCDF is used in the Canadian nuclear licensing process, while the Farmer limit line approach, supplemented by separate qualitative limits on overall risk, is employed in the United Kingdom

    This note presents a direct adjustment of the estimative prediction limit to reduce the coverage error from a target value to third-order accuracy. The adjustment is asymptotically equivalent to those of Barndorff-Nielsen & Cox (1994, 1996) and Vidoni (1998). It has a simpler form with a plug-in estimator of the coverage probability of the estimative limit at the target value. Copyright 2007, Oxford University Press.

    Abstract. Let S be a scheme. Assume that we are given an action of the one dimen- sional split torus Gm,S on a smooth affine S-scheme X. We consider the limit (also called attractor) subfunctor Xλ consisting of points whose orbit under the given action. 'admits a limit at 0'. We show that Xλ is representable by a smooth ...

    The paper touches upon the issues of NPP safety ensuring at the stage of fuel load design and operation by applying special limitations for a series of parameters, that is, design limits. Two following approaches are compared: the one used by west specialists for the PWR reactor and the Russian approach employed for the WWER reactor. The closeness of approaches is established, differences that are mainly peculiarities of terms are noted (Authors)
