: Results of a search for the electroweak associated production of charginos and next-to-lightest neutralinos, pairs of charginos or pairs of tau sleptons are presented. These processes are characterised by final states with at least two hadronically decaying tau leptons, missing transverse momentum and low jet activity. The analysis is based on an integrated luminosity of 20.3 fb−1 of proton-proton collisions at recorded with the ATLAS experiment at the Large Hadron Collider. No significant excess is observed with respect to the (...) predictions from Standard Model processes. Limits are set at 95% confidence level on the masses of the lighter chargino and next-to-lightest neutralino for various hypotheses for the lightest neutralino mass in simplified models. In the scenario of direct production of chargino pairs, with each chargino decaying into the lightest neutralino via an intermediate tau slepton, chargino masses up to 345 GeV are excluded for a massless lightest neutralino. For associated production of mass-degenerate charginos and next-to-lightest neutralinos, both decaying into the lightest neutralino via an intermediate tau slepton, masses up to 410 GeV are excluded for a massless lightest neutralino.[Figure not available: see fulltext.].

The World Trade Organization Agreement on the Application of Sanitary andPhytosanitary Measures (the SPS Agreement) isa product of international efforts to blendtrade liberalization with standards of publichealth protection. One of the aims of theAgreement is to facilitate the pre-emption andmanagement of food safety related tradedisputes. An examination of nineteenth-centuryand modern-day trade disputes illustrates howthe SPS Agreement is positioned to carry outthis remit. Historical research andcontemporary experience vindicate the Agreementas a necessary treaty to address severalfactors that influence food safety relatedtrade disputes: (...) economic considerations, riskperception, and regulatory coordination.

The PUC in São Paulo is a college of the Church and keeps the catholic identity. In the academic range, the university preserves its identity, ensures its autonomy in relation to the good of the Church and maintains a dialogue with society. Gospel values should be preserved for an efficient and mature scientific reflection. This article indicates the Apostolic Constitution of the Supreme Pontiff John Paul II, about the catholic universities, and presents the instruction on the Ecclesial Vocation of the (...) theologian of the Congregation for the Doctrine of the Faith. In fact, what is the contribution of the catholic university to society? What is the relationship between Revelation and Reason as an authentic and mature scientific reflection in PUC SP? How to understand catholic identity and university’s autonomy? (shrink)
We investigate the notion of hyperimmunity with respect to how it can be applied to Π{\sp 0}{\sb 1} classes and their Muchnik degrees. We show that hyperimmunity is a strong enough concept to prove the existence of Π{\sp 0}{\sb 1} classes with intermediate Muchnik degree—in contrast to Post's attempts to construct intermediate c.e. degrees.
The aim of this book is “to point how far the Arabian philosophers succeeded in their attempt to integrate the Semitic and Muslim conception of revelation with Greek wisdom.” The problem is precisely that which confronted the Catholic theologians of the 13th century. Seeing the efforts of the Arabian philosophers side by side with the achievement of St. Thomas we can better appreciate what St. Thomas succeeded in doing.
Psychological traits and disorders are often interrelated through shared genetic influences. A combination of maximum-likelihood structural equation modelling and multidimensional scaling enables us to open a window onto the genetic architecture at the symptom level, rather than at the level of latent genetic factors. We illustrate this approach using a study of cognitive abilities involving over 5,000 pairs of twins.
