    BSAURUS- A Package For Inclusive B-Reconstruction in DELPHI

    Get PDF
    BSAURUS is a software package for the inclusive reconstruction of B-hadrons in Z-decay events taken by the DELPHI detector at LEP. The BSAURUS goal is to reconstruct B-decays, by making use of as many properties of b-jets as possible, with high efficiency and good purity. This is achieved by exploiting the capabilities of the DELPHI detector to their extreme, applying wherever possible physics knowledge about B production and decays and combining different information sources with modern tools- mainly artificial neural networks. This note provides a reference of how BSAURUS outputs are formed, how to access them within the DELPHI framework, and the physics performance one can expect.Comment: 52 pages, 24 figures, added author Z.

    Europeanizing territoriality—towards soft spaces?

    Get PDF
    This paper explores the coexistence of relational and territorial spaces—soft spaces—through the experiences of EU integration and territorialization. First, we seek a better understanding of EU integration through an engagement with the literature and research on soft spaces. We propose that EU integration is best understood as involving an interplay between territorial and relational understandings and approaches that vary through time, a variation that can be categorized as involving pooled territoriality, supraterritoriality, and nonterritoriality. Second, we seek to add to the current research and literature on soft spaces by focusing upon the changing character of soft spaces and their temporalities. We approach these two dimensions through an exploration of two ex post case studies, the development of which typically shows different stages of softening, hardening, and of differing degrees of Europeanization. With the focus on Europeanization, the paper concludes with three findings: the new spaces of European territoriality are characterized by, first, temporal dynamics, second, their parallel existence with ‘hard’ spaces, and, finally, they can be employed as a political tool.

    Benocyclidine (BTCP) as Non‐labelled Reporter Ligand for MS Binding Assays for the PCP Ion Channel Binding Site of the Desensitized Torpedo Nicotinic Acetylcholine Receptor (nAChR)

    In this study we present MS Binding Assays for the PCP ion channel binding site of Torpedo californica nicotinic acetylcholine receptor (nAChR) as an alternative to radioligand binding assays. As MS Marker Benocyclidine (BTCP) was employed, found to be more affine (Kd of 84.2 nM) than the radioligands, e. g. [3H]PCP, used so far in respective binding assays. Based on a highly sensitive and fast LC-ESI-MS/MS method for quantification of BTCP samples, BTCP MS Binding Assays for the PCP ion channel binding site of Torpedo nAChR could be established comprising saturation, kinetic and competition experiments. The affinities obtained in competitive BTCP MS Binding Assays for ligands addressing the PCP ion channel binding site of Torpedo nAChR were in excellent accord with those reported from radioligand experiments. Thus, the new BTCP MS Binding Assays represent a potent and reliable alternative to radioligand binding assays used so far for the characterization of ligand binding to the PCP ion channel binding site of the nAChR

    Observation of enhanced rate coefficients in the H2+_2^+ + H2_2 →\rightarrow H3+_3^+ + H reaction at low collision energies

    Full text link
    The energy dependence of the rate coefficient of the H2+ +H2→H3++H_2^+\ + {\rm H}_2 \rightarrow {\rm H}_3^+ + {\rm H} reaction has been measured in the range of collision energies between kB⋅10k_\mathrm{B}\cdot 10 K and kB⋅300k_\mathrm{B}\cdot 300 mK. A clear deviation of the rate coefficient from the value expected on the basis of the classical Langevin-capture behavior has been observed at collision energies below kB⋅1k_\mathrm{B}\cdot 1 K, which is attributed to the joint effects of the ion-quadrupole and Coriolis interactions in collisions involving ortho-H2_2 molecules in the j=1j = 1 rotational level, which make up 75% of the population of the neutral H2_2 molecules in the experiments. The experimental results are compared to very recent predictions by Dashevskaya, Litvin, Nikitin and Troe (J. Chem. Phys., in press), with which they are in agreement.Comment: 14 pages, 3 figure

    The risk of austerity co-production in city-regional governance in England

    Get PDF
    This article examines the risk of what we term ‘austerity co‐production’, a weak form of collaborative governance shaped by resource scarcity and fragmented, multiple forms of expertise. Despite the hope that co‐production has radical potential to solve governance challenges across city‐regions, not enough attention has been paid to the institutional contexts in which co‐production is developed. We argue this institutional context is crucial in shaping how co‐production comes to ground and the conditions it reproduces. We draw on a critical case study of metropolitan policymaking in Greater Manchester, England, to examine the gap between imagined and actual institutional contexts for co‐production. We develop a framework that can be applied in different policy areas to assess the potential implementation of co‐production in city‐regional governance. Whilst the promise of co‐production remains, we conclude that austerity co‐production risks operating as an already‐existing default solution to urban problems that constrains more innovative approaches to the governance and politics of the city‐region

    On the problem of the justification of river rights

    Get PDF
    This article aims to work out the social conditions that determine whether the communication of river rights finds success in society. Employing the context of hydropower development in the Mekong region, the article finds that an essentialist strategy which claims that river rights have unlimited ‘moral’ validity regardless of any of the decision consequences is unlikely to succeed. Instead, it is proposed that moral conflicts over river rights may ultimately only be resolvable ‘unmorally’, that is, by procedural legitimacy – and this is best captured by employing a methodological framework composed of thematic, social and temporal dimension
