Small clause results revisited

The main purpose of this paper is to show that argument structure constructions like complex telic path of motion constructions (John walked to the store) or complex resultative constructions (The dog barked the chickens awake) are not to be regarded as "theoretical entities" (Jackendoff (1997b); Goldberg (1995)). As an alternative to these semanticocentric accounts, I argue that their epiphenomenal status can be shown iff we take into account some important insights from three syntactically-oriented works: (i) Hoekstra's (1988, 1992) analysis of SC R, (ii) Hale & Keyser's (1993f.) configurational theory of argument structure, and (iii) Mateu & Rigau’s (1999; i.p.) syntactic account of Talmy's (1991) typological distinction between 'satellite framed languages' (e.g., English, German, Dutch, etc.) and 'verb-framed languages' (e.g., Catalan, Spanish, French, etc.). In particular, it is argued that the formation of the abovementioned constructions involves a conflation process of two different syntactic argument structures, this process being carried out via a 'generalized transformation'. Accordingly, the so-called 'lexical subordination process' (Levin & Rapoport (1988)) is argued to involve a syntactic operation, rather than a semantic one. Due to our assuming that the parametric variation involved in the constructions under study cannot be explained in purely semantic terms (Mateu & Rigau (1999)), Talmy's (1991) typological distinction is argued to be better stated in lexical syntactic terms

An Integral geometry based method for fast form-factor computation

Monte Carlo techniques have been widely used in rendering algorithms for local integration. For example, to compute the contribution of a patch to the luminance of another. In the present paper we propose an algorithm based on Integral geometry where Monte Carlo is applied globally. We give some results of the implementation to validate the proposition and we study the error of the technique, as well as its complexity.Postprint (published version

Third-Harmonic and intermodulation distortion in bulk acoustic-wave resonators

This article discusses on the measured third-order intermodulation (IMD3) products and third harmonics (H3) appearing in a set of six different solidly mounted resonators (SMR) and bulk acoustic-wave (BAW) resonators with different shapes and stack configurations. The discussion is supported by a comprehensive nonlinear distributed circuit model that considers the nonlinear effects potentially occurring in any layer of the resonator stack. The aluminum-nitride (AlN) and silicon-dioxide (SiO2) layers are identified as the most significant contributors to the IMD3 and H3. The frequency profile of the third-order spurious signals also reveals that, in temperature-compensated resonators, where the SiO2 layers are usually thicker, the remixing effects from the second-order nonlinear terms are the major contributors to the IMD3 and H3. These second-order terms are those that explain the second-harmonic (H2) generation, whose measurements are also reported in this article. Unique values of the nonlinear material constants can explain all the measurements despite the resonators have different shapes, resonance frequencies, and stack configurations.Peer ReviewedPostprint (author's final draft

Point patterns occurring on complex structures in space and space-time: An alternative network approach

This paper presents an alternative approach of analyzing possibly multitype point patterns in space and space-time that occur on network structures, and introduces several different graph-related intensity measures. The proposed formalism allows to control for processes on undirected, directional as well as partially directed network structures and is not restricted to linearity or circularity

Existence of corotating and counter-rotating vortex pairs for active scalar equations

In this paper, we study the existence of corotating and counter-rotating pairs of simply connected patches for Euler equations and the $(\hbox{SQG})_\alpha$ equations with $\alpha\in (0,1).$ From the numerical experiments implemented for Euler equations in \cite{DZ, humbert, S-Z} it is conjectured the existence of a curve of steady vortex pairs passing through the point vortex pairs. There are some analytical proofs based on variational principle \cite{keady, Tur}, however they do not give enough information about the pairs such as the uniqueness or the topological structure of each single vortex. We intend in this paper to give direct proofs confirming the numerical experiments and extend these results for the $(\hbox{SQG})_\alpha$ equation when $\alpha\in (0,1)$. The proofs rely on the contour dynamics equations combined with a desingularization of the point vortex pairs and the application of the implicit function theorem.Comment: 39 pages, we unified some section

Chiral Perturbation Theory with tensor sources

We construct the most general chirally-invariant Lagrangian for mesons in the presence of external sources coupled to the tensor current \bar{\psi}\sigma_{\mu\nu}\psi. In order to have only even terms in the chiral expansion, we consider the new source of O(p^2). With this choice, we build the even-parity effective Lagrangian up to the p^6-order (NLO). While there are only 4 new terms at the p^4-order, at p^6-order we find 78 terms for n_f=2 and 113 terms for n_f=3. We provide a detailed discussion on the different mechanisms that ensure that our final set of operators is complete and non-redundant. We also examine the odd-parity sector, to conclude that the first operators appear at the p^8-order (NNLO).Comment: 23 pages, one figure; typos corrected, one paragraph added, new section added, references added, published versio
