Multiple Motivations Consequences on Bidder's Optimal Strategy in Takeover Contests
2011
This paper examines the optimal bidding strategy in takeover contests for a target firm, and the positive correlation between the bidders’ valuation. We consider risk neutral bidders who compete for the control of a target firm in which they get initial shareholdings. The bidder valuation for target firm is correlated with his motivations which determine the bidder’s strategy. We study bidder’s optimal strategy in mixed motivations setting. Since motivations are numerous, hypothesis of affiliated value in auctions allows to study bidder’s strategy. The paper shows that the impact of affiliation degree on bidder’s optimal strategy depends on their private signal and on the ratio between thei…
Precision electroweak measurements on the Z resonance
2005
We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLD experiment using a polarised beam at SLC. The measurements include cross-sections, forward-backward asymmetries and polarised asymmetries. The mass and width of the Z boson, $\MZ$ and $\GZ$, and its couplings to fermions, for example the $\rho$ parameter and the effective electroweak mixing angle, are precisely measured. The number of light neutrino species is determined to be 2.9840…
A search for flavour changing neutral currents in top-quark decays in pp collision data collected with the ATLAS detector at root s=7 TeV
2012
A search for flavour changing neutral current (FCNC) processes in top-quark decays by the ATLAS Collaboration is presented. Data collected from pp collisions at the LHC at a centre-of-mass energy of √s = 7 TeV during 2011, corresponding to an integrated luminosity of 2.1 fb[superscript −1], were used. A search was performed for top-quark pair-production events, with one top quark decaying through the t → Zq FCNC (q = u, c) channel, and the other through the Standard Model dominant mode t → W b. Only the decays of the Z boson to charged leptons and leptonic W -boson decays were considered as signal. Consequently, the final-state topology is characterised by the presence of three isolated cha…

Optimal Hedging of Option Portfolios with Transaction Costs
2006
One of the most successful approaches to option hedging with transaction costs is the utility based approach pioneered by Hodges and Neuberger (1989). However, this approach has one major drawback that prevents the broad application of this approach in practice: the lack of a closed-form solution. The direct numerical computations of the utility based hedging strategy are cumbersome in a practical implementation. Despite some recent advances in finding an explicit description of the utility based hedging strategy by using either asymptotic, approximation, or other methods, so far they were concerned primarily with hedging a single plain-vanilla option. However, in practice one often faces t…
A Trans-amplifying RNA Vaccine Strategy for Induction of Potent Protective Immunity
2019
Here, we present a potent RNA vaccine approach based on a novel bipartite vector system using trans-amplifying RNA (taRNA). The vector cassette encoding the vaccine antigen originates from an alphaviral self-amplifying RNA (saRNA), from which the replicase was deleted to form a transreplicon. Replicase activity is provided in trans by a second molecule, either by a standard saRNA or an optimized non-replicating mRNA (nrRNA). The latter delivered 10- to 100-fold higher transreplicon expression than the former. Moreover, expression driven by the nrRNA-encoded replicase in the taRNA system was as efficient as in a conventional monopartite saRNA system. We show that the superiority of nrRNA- ov…
A vueltas con la traducción en el siglo XXI
2009
El concepto de traducción ha cambiado muchísimo durante las últimas décadas: hemos pasado de la equivalencia absoluta a la ampliación de la definición de este campo hasta límites a veces insospechados. Y es que, efectivamente, la traducción es siempre reflejo del tipo de sociedad que la genera, así que no es de extrañar que una cultura como la occidental, contradictoria, híbrida, enriquecida por las migraciones pero también cargada de problemas por los choques interculturales, ofrezca una definición de traducción que es ahora un proceso nunca neutro y éticamente complejo. Las distintas teorías contemporáneas ayudan mucho a reflexionar sobre todo ello, y reflejan las elecciones que como trad…
Rethinking translation in the 21st century
2009
In the latest decades the concept of translation has dramatically changed: we have gone from absolute equivalence to a widening of the definition of this field which sometimes reaches unforeseen limits. Translation certainly reflects the kind of society which produces it and, thus, it is hardly surprising that a culture like the western one – contradictory, hybrid and enriched thanks to migration but at the same time burdened with problems arising from cross-cultural clashes – offers a definition of translation as a never-neutral and ethically-complex process. The different current theories provide much help when pondering over these issues and reflect the choices which we, translators, con…
Normative Legal Positivism, Neutrality, and the Rule of Law
2013
Usually, in jurisprudential debates what is discussed under the rubric of ‘neutrality’ is the claim that jurisprudence is (or at least can, and should be) a conceptual, or descriptive - thus, non-normative, or morally neutral - inquiry. I discuss neutrality in an altogether different sense, namely, neutrality as an ethico-political ideal the law should meet. My starting point is normative legal positivism, or the claim that it is a good and desirable thing that the laws have easily identifiable, readily accessible, as far as possible non-controversial social sources. What justifies normative legal positivism, I claim, is the value - or the ideal - of neutrality, suitably understood. I.e., w…
Energy harvesting by waste acid/base neutralization via bipolar membrane reverse electrodialysis
2020
Bipolar Membrane Reverse Electrodialysis (BMRED) can be used to produce electricity exploiting acid-base neutralization, thus representing a valuable route in reusing waste streams. The present work investigates the performance of a lab-scale BMRED module under several operating conditions. By feeding the stack with 1 M HCl and NaOH streams, a maximum power density of ~17 W m−2 was obtained at 100 A m−2 with a 10-triplet stack with a flow velocity of 1 cm s−1, while an energy density of ~10 kWh m−3 acid could be extracted by a complete neutralization. Parasitic currents along feed and drain manifolds significantly affected the performance of the stack when equipped with a higher number of t…
