    Jurisdiction shopping and foreign location choice: The role of market and nonmarket experience in the European solar energy industry

    Several countries provide policy support to specific sectors in order to facilitate industry transitions. While industry-support policies stimulate the growth of their target sectors, little is known about how such policies engender heterogeneous international strategies. In this article, we investigate how industry-support policies influence foreign location choices. We argue that firms engage in jurisdiction shopping, choosing to invest in countries with more generous policy support, but that this tendency varies markedly across firms. Specifically, we suggest that firms’ nonmarket experience exacerbates the effect of policy support on location choice, whereas market experience has less of an impact. Further, we propose that some firms view generous policies more skeptically than others, depending on the nature of their nonmarket experience. We test and find support for our predictions using a longitudinal dataset of foreign investments of firms entering the solar energy industry in the European Union. Our findings indicate that supportive policies stimulate the energy transition, attracting in particular foreign entrants diversifying into renewables or having more policy experience. At the same time, they suggest that adverse policy changes in one country affect how firms assess policies in other countries, highlighting the need for policy coordination at a supranational level

    The Azambuja fault: An active structure located in an intraplate basin with significant seismicity (Lower Tagus Valley, Portugal)

    Get PDF
    The Azambuja fault is a NNE trending structure located 50 km NE of Lisbon, in an area of important historical seismicity. It is sited in the Lower Tagus Basin, a compressive foredeep basin related to tectonic inversion of the Mesozoic Lusitanian Basin in the Miocene. The fault is evident in commercial seismic reflection data, where it shows steep thrust geometry downthrowing the Cenozoic sediments to the east. It has also a clear morphological signature, presenting a NNE-SSW trending, east facing, 15 km long scarp, reaching a maximum height of 80 m. The fault scarp is the geomorphic appearance of a flexure expressed as a zone of distributed deformation, where Miocene and Pliocene sediments are tilted eastwards and are cut by steeply dipping meso-scale faults presenting reverse and normal offsets, with a net downthrow to the east. This pattern at the surface is compatible with a steep fault in the basement that tilts and branches through the overlying Cenozoic sedimentary cover. In order to constrain the neotectonic activity of this structure, detailed geological studies were conducted. Morphotectonics was studied through aerial photo interpretation, analysis of topographic maps and digital mapping. Those studies indicate Quaternary slip on the fault in the ranges of 0.05–0.06 mm per year. Seismogenic behaviour was assumed for the Azambuja fault based on the evidence of Quaternary tectonic activity and its location in an area of significant historical seismicity. Mw 6.4–6.7 maximum earthquakes, with recurrence intervals of 10000–25000 years, were estimated based upon the displaced morphological references, cumulative offsets and fault length

    Cosmic String in Scalar-Tensor Gravity

    Get PDF
    The gravitational properties of a local cosmic string in the framework of scalar-tensor gravity are examined. We find the metric in the weak-field approximation and we show that, contrary to the General Relativity case, the cosmic string in scalar-tensor gravitation exerces a force on non-relativistic, neutral test particle. This force is proportional to the derivative of the conformal factor A2(ϕ)A^{2}(\phi) and it is always attractive. Moreover, this force could have played an important role at the Early Universe, although nowadays it can be neglegible. It is also shown that the angular separation δφ\delta\varphi remains unaltered for scalar-tensor cosmic strings.Comment: 15 pages, LATEX, no figure

    Pseudoalignment for metagenomic read assignment

    Get PDF
    Motivation: Read assignment is an important first step in many metagenomic analysis workflows, providing the basis for identification and quantification of species. However ambiguity among the sequences of many strains makes it difficult to assign reads at the lowest level of taxonomy, and reads are typically assigned to taxonomic levels where they are unambiguous. We explore connections between metagenomic read assignment and the quantification of transcripts from RNA-Seq data in order to develop novel methods for rapid and accurate quantification of metagenomic strains. Results: We find that the recent idea of pseudoalignment introduced in the RNA-Seq context is highly applicable in the metagenomics setting. When coupled with the Expectation-Maximization (EM) algorithm, reads can be assigned far more accurately and quickly than is currently possible with state of the art software, making it possible and practical for the first time to analyze abundances of individual genomes in metagenomics projects

    Endoscopic Submucosal Dissection of Early Gastric Cancer Using the Insulated Tip Knife

    Get PDF
    AbstractEndoscopic submucosal dissection (ESD) is an endoscopic technique in which a gastrointestinal mucosal neoplasm can be excised by cutting through the submucosa with an endoscopic knife. It can be used with diagnostic or therapeutic intent and allows en bloc removal of the specimen. ESD usually begins with identification and evaluation of the lesion and assessment of the margin with chromo-endoscopy. The subsequent steps include marking, submucosal injection, and circumferential and submucosal dissection. Complications should be promptly recognized and dealt with immediately if necessary.This video demonstrates the main steps of the technique and management of complications.

    Crystal structures and proton dynamics in potassium and cesium hydrogen bistrifluoroacetate salts with strong symmetric hydrogen bonds

    Get PDF
    The crystal structures of potassium and cesium bistrifluoroacetates were determined at room temperature and at 20 K and 14 K, respectively, with the single crystal neutron diffraction technique. The crystals belong to the I2/a and A2/a monoclinic space groups, respectively, and there is no visible phase transition. For both crystals, the trifluoroacetate entities form dimers linked by very short hydrogen bonds lying across a centre of inversion. Any proton disorder or double minimum potential can be rejected. The inelastic neutron scattering spectral profiles in the OH stretching region between 500 and 1000 cm^{-1} previously published [Fillaux and Tomkinson, Chem. Phys. 158 (1991) 113] are reanalyzed. The best fitting potential has the major characteristics already reported for potassium hydrogen maleate [Fillaux et al. Chem. Phys. 244 (1999) 387]. It is composed of a narrow well containing the ground state and a shallow upper part corresponding to dissociation of the hydrogen bond.Comment: 31 pages, 7 figure

    Generalized Hermite-Gauss decomposition of the two-photon state produced by spontaneous parametric down-conversion

    Full text link
    We provide a general decomposition of the two-photon state produced by spontaneous parametric down-conversion in Hermite-Gaussian modes, in the case that the pump beam is described by a Hermite-Gaussian beam of any order. We show that the spatial correlations depend explicitly on the order of the pump beam, as well as other experimental parameters. We use the decomposition to demonstrate a few interesting cases. Our results are applicable to the engineering of two-photon spatial entanglement, in particular for non-Gaussian states.Comment: 14 page draft, 5 figure
