BSAURUS- A Package For Inclusive B-Reconstruction in DELPHI
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 territorialityâtowards soft spaces?
This paper explores the coexistence of relational and territorial spacesâsoft spacesâthrough 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 âhardâ spaces, and, finally, they can be employed as a political tool.

Benocyclidine (BTCP) as Nonâlabelled 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 84.2â
nM) than the radioligands, e.âg. [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 H + H H + H reaction at low collision energies
The energy dependence of the rate coefficient of the H reaction has been measured in the range of
collision energies between K and
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 K, which is attributed to the joint
effects of the ion-quadrupole and Coriolis interactions in collisions involving
ortho-H molecules in the rotational level, which make up 75% of the
population of the neutral H 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
This article examines the risk of what we term âausterity coâproductionâ, a weak form of collaborative governance shaped by resource scarcity and fragmented, multiple forms of expertise. Despite the hope that coâproduction has radical potential to solve governance challenges across cityâregions, not enough attention has been paid to the institutional contexts in which coâproduction is developed. We argue this institutional context is crucial in shaping how coâproduction 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 coâproduction. We develop a framework that can be applied in different policy areas to assess the potential implementation of coâproduction in cityâregional governance. Whilst the promise of coâproduction remains, we conclude that austerity coâproduction risks operating as an alreadyâexisting default solution to urban problems that constrains more innovative approaches to the governance and politics of the cityâregion
On the problem of the justification of river rights
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 âmoralâ 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 âunmorallyâ, that is, by
procedural legitimacy â and this is best captured by employing a methodological
framework composed of thematic, social and temporal dimension
