We present a parton-level study of electro-weak production of vector-boson pairs at the Large Hadron Collider, establishing the sensitivity to a set of dimension-six operators in the ...Standard Model Effective Field Theory (SMEFT). Different final states are statistically combined, and we discuss how the orthogonality and interdependence of different analyses must be considered to obtain the most stringent constraints. The main novelties of our study are the inclusion of SMEFT effects in non-resonant diagrams and in irreducible QCD backgrounds, and an exhaustive template analysis of optimal observables for each operator and process considered. We also assess for the first time the sensitivity of vector-boson-scattering searches in semileptonic final states.

We present the first parton-level study of anomalous effects in triboson production in both fully and semi-leptonic channels in proton-proton collisions at 13 TeV at the Large Hadron ...Collider (LHC). The sensitivity to anomalies induced by a minimal set of bosonic dimension-6 operators from the Warsaw basis is evaluated with specific analyses for each final state. A likelihood-based strategy is employed to assess the most sensitive kinematic observables per channel, where the contribution of Effective Field Theory operators is parameterized at either the linear or quadratic level. The impact of the mutual interference terms of pairs of operators on the sensitivity is also examined. This benchmark study explores the complementarity and overlap in sensitivity between different triboson measurements and paves the way for future analyses at the LHC experiments. The statistical combination of the considered final states allows setting stringent bounds on five bosonic Wilson coefficients.
In this paper we show that bank competition has an intrinsically ambiguous impact on capital accumulation. We further show that it is also responsible for the emergence of development traps in ...economies that otherwise would be characterized by unique equilibria. These results explain the conflicting evidence emerging from the recent empirical studies of the effects of bank competition on economic growth. We obtain them developing a dynamic, general equilibrium model of capital accumulation where banks operate in a Cournot oligopoly. More banks lead to a higher quantity of credit available to entrepreneurs, but also to diminished incentives to offer relationship services that improve the likelihood of success of investment projects. We also show that conditioning on one key parameter resolves the theoretical ambiguity: in economies where intrinsic market uncertainty is high (low), less (more) competition leads to higher capital accumulation.
The proteins present in the uterine secretions of pigs change both quantitatively and qualitatively during the normal estrous cycle. One of these proteins, which comprises about 15% of the total at ...Day 15 after estrus, is strongly basic and migrates toward the cathode during polyacrylamide gel electrophoresis at pH 7.0. It also has a characteristic lavender color with an extinction maximum at 545 nm (ε = 1.76 x 103) and gives a positive reaction with periodic acidSchiff stain. In nonpregnant animals this protein is present in the uterus only between Days 12 and 16 after estrus but is absent from serum. It can, however, be induced at approximately the same time in ovariectomized animals given daily doses of progesterone or progesterone plus estrogen. Estrogen alone is ineffective. The protein has been purified from both normal and ovariectomized animals given progesterone by successive chromatography on Sephadex G-100 and CM-cellulose. It was homogeneous as determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis and by immunodiffusion criteria. The protein has a molecular weight of about 32,000 and an isoelectric point at approximately pH 9.7. Large amounts of basic amino acids are present and the molecule is about 12.5% carbohydrate by weight. Antiserum prepared against this protein does not cross-react with extracts from tissues other than the uterus.

These results explain the conicting evidence emerging from the recent empirical studies of the e¤ects of bank competition on economic growth. We obtain them developing a dynamic, general equilibrium model of capital accumulation where banks operate in a Cournot oligopoly. More banks lead to a higher quantity of credit available to entrepreneurs, but also to diminished incentives to o¤er relationship services which contribute to improve the likelihood of success of entrepreneursprojects. This tension between credit quantity and credit quality is what leads to the ambiguous e¤ect on capital accumulation, We also show that conditioning on one key parameter resolves the theoretical ambiguity: in economies where intrinsic market uncertainty is high (low), less (more) competition leads to higher capital accumulation.
This paper shows that bank competition has an intrinsically ambiguous effect on capital accumulation and economic growth. We further demonstrate that banking market structure can be responsible for ...the emergence of development traps in economies that would otherwise be characterized by unique steady-state equilibria. These predictions explain the conflicting evidence gathered from recent empirical studies of how bank competition affects the real economy. Our results were obtained by developing a dynamic general-equilibrium model of capital accumulation in which banks operate in a Cournot oligopoly. The presence of more banks leads to a higher quantity of credit available to entrepreneurs, but also to diminished incentives to screen loan applicants and thus to poorer capital allocation. We also show that conditioning on economic parameters describing the quality of the entrepreneurial population resolves the theoretical ambiguity. In economies where the average prospective entrepreneur is of low credit quality and where screening would therefore be especially beneficial, less competition leads to higher capital accumulation. The opposite is true when entrepreneurs are innately of higher credit quality.
