    Get PDF
    In today\u27s global market, disputes between U.S. and foreign parties have become a common occurrence. Courts in the United States, as well as other nations, frequently face new and complex international litigation problems. A common problem for many courts centers on the practical, mechanical requirements of bringing a lawsuit. In this Article, the author examines the service of process of U.S. complaints for punitive damages to residents of Germany. In particular, Ms. Lenhardt analyzes the recent German Constitutional Court\u27s ruling on international service of process. In addition, the author reviews the requirements of the Hague Convention on Service Abroad and the procedures that must be followed by foreign plaintiff swishing to serve process to German residents. Finally, Ms.Lenhardt summarizes the German Constitutional Court\u27s decision on the treatment of punitive damages claims and the relation and impact these claims have on the requirements for service of process

    Probing Nuclear forces beyond the drip-line using the mirror nuclei 16^{16}N and 16^{16}F

    Radioactive beams of 14^{14}O and 15^{15}O were used to populate the resonant states 1/2+^+, 5/2+^+ and 0,1,20^-,1^-,2^- in the unbound 15^{15}F and 16^{16}F nuclei respectively by means of proton elastic scattering reactions in inverse kinematics. Based on their large proton spectroscopic factor values, the resonant states in 16^{16}F can be viewed as a core of 14^{14}O plus a proton in the 2s1/2_{1/2} or 1d5/2_{5/2} shell and a neutron in 1p1/2_{1/2}. Experimental energies were used to derive the strength of the 2s1/2_{1/2}-1p1/2_{1/2} and 1d5/2_{5/2}-1p1/2_{1/2} proton-neutron interactions. It is found that the former changes by 40% compared with the mirror nucleus 16^{16}N, and the second by 10%. This apparent symmetry breaking of the nuclear force between mirror nuclei finds explanation in the role of the large coupling to the continuum for the states built on an =0\ell=0 proton configuration.Comment: 6 pages, 3 figures, 2 tables, accepted for publication as a regular article in Physical Review

    New pathway to bypass the 15O waiting point

    Full text link
    We propose the sequential reaction process 15^{15}O(pp,γ)(β+\gamma)(\beta^{+})16^{16}O as a new pathway to bypass of the 15^{15}O waiting point. This exotic reaction is found to have a surprisingly high cross section, approximately 1010^{10} times higher than the 15^{15}O(pp,β+\beta^{+})16^{16}O. These cross sections were calculated after precise measurements of energies and widths of the proton-unbound 16^{16}F low lying states, obtained using the H(15^{15}O,p)15^{15}O reaction. The large (p,γ)(β+)(p,\gamma)(\beta^{+}) cross section can be understood to arise from the more efficient feeding of the low energy wing of the ground state resonance by the gamma decay. The implications of the new reaction in novae explosions and X-ray bursts are discussed.Comment: submitte

    Effective Rheology of Bubbles Moving in a Capillary Tube

    Full text link
    We calculate the average volumetric flux versus pressure drop of bubbles moving in a single capillary tube with varying diameter, finding a square-root relation from mapping the flow equations onto that of a driven overdamped pendulum. The calculation is based on a derivation of the equation of motion of a bubble train from considering the capillary forces and the entropy production associated with the viscous flow. We also calculate the configurational probability of the positions of the bubbles.Comment: 4 pages, 1 figur

    We present an all solid-state narrow line-width laser source emitting 670mW670\,\mathrm{mW} output power at 671nm671\,\mathrm{nm} delivered in a diffraction-limited beam. The \linebreak source is based on a fre-quency-doubled diode-end-linebreak pumped ring laser operating on the 4F3/24I13/2{^4F}_{3/2} \rightarrow {^4I}_{13/2} transition in Nd:YVO4_4. By using periodically-poled po-tassium titanyl phosphate (ppKTP) in an external build-up cavity, doubling efficiencies of up to 86% are obtained. Tunability of the source over 100GHz100\,\rm GHz is accomplished. We demonstrate the suitability of this robust frequency-stabilized light source for laser cooling of lithium atoms. Finally a simplified design based on intra-cavity doubling is described and first results are presented

    Ab Initio Screening Approach for the Discovery of Lignin Polymer Breaking Pathways

    Get PDF
    The directed depolymerization of lignin biopolymers is of utmost relevance for the valorization or commercialization of biomass fuels. We present a computational and theoretical screening approach to identify potential cleavage pathways and resulting fragments that are formed during depolymerization of lignin oligomers containing two to six monomers. We have developed a chemical discovery technique to identify the chemically relevant putative fragments in eight known polymeric linkage types of lignin. Obtaining these structures is a crucial precursor to the development of any further kinetic modeling. We have developed this approach by adapting steered molecular dynamics calculations under constant force and varying the points of applied force in the molecule to diversify the screening approach. Key observations include relationships between abundance and breaking frequency, the relative diversity of potential pathways for a given linkage, and the observation that readily cleaved bonds can destabilize adjacent bonds, causing subsequent automatic cleavage.Massachusetts Institute of Technology (Research Support Corporation, Reed Grant)United States.

    Selected parameters of quality (hydroxyproline, calcium, bone particles content, and histological determination of bone particles) of mechanically deboned poultry meat (MDPM - „firmseparation“ and soft separation „Baadermeat“) were compared. Comparison of results with composition (except bone particles) of fresh poultry meat (breast and thigh muscles) was performed. Hydroxyproline content was significantly different and the mean value of hydroxyproline content was in mechanically deboned meat more than two-fold higher in comparison with Baader meat (333.17 mg.100g-1, 152.90 mg.100g-1 respectively). Similar results were achieved in calcium content (1.94g.kg-1, 1.05 g.kg-1 respectively). The mean content of bone particles was 0.27 % (MDPM) and 0.034 % (Baader). Finally, histological determination of bone particles in MDPM and Baader meat was carried out.U radu su uspoređeni odabrani parametri kakvoće (hidroksiprolin, kalcij, sadržaj čestica kostiju i histološko određivanje čestica kostiju) strojno otkošteog mesa peradi (engl. mechanically deboned poultry meat; MDPM -„čvrsta separacija“ i „meka separacija“ „Baader meso“).

    <i>Gaia</i> Data Release 1. Summary of the astrometric, photometric, and survey properties

    Get PDF
    Context. At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7. Aims. A summary of Gaia DR1 is presented along with illustrations of the scientific quality of the data, followed by a discussion of the limitations due to the preliminary nature of this release. Methods. The raw data collected by Gaia during the first 14 months of the mission have been processed by the Gaia Data Processing and Analysis Consortium (DPAC) and turned into an astrometric and photometric catalogue. Results. Gaia DR1 consists of three components: a primary astrometric data set which contains the positions, parallaxes, and mean proper motions for about 2 million of the brightest stars in common with the HIPPARCOS and Tycho-2 catalogues – a realisation of the Tycho-Gaia Astrometric Solution (TGAS) – and a secondary astrometric data set containing the positions for an additional 1.1 billion sources. The second component is the photometric data set, consisting of mean G-band magnitudes for all sources. The G-band light curves and the characteristics of ∼3000 Cepheid and RR-Lyrae stars, observed at high cadence around the south ecliptic pole, form the third component. For the primary astrometric data set the typical uncertainty is about 0.3 mas for the positions and parallaxes, and about 1 mas yr−1 for the proper motions. A systematic component of ∼0.3 mas should be added to the parallax uncertainties. For the subset of ∼94 000 HIPPARCOS stars in the primary data set, the proper motions are much more precise at about 0.06 mas yr−1. For the secondary astrometric data set, the typical uncertainty of the positions is ∼10 mas. The median uncertainties on the mean G-band magnitudes range from the mmag level to ∼0.03 mag over the magnitude range 5 to 20.7. Conclusions. Gaia DR1 is an important milestone ahead of the next Gaia data release, which will feature five-parameter astrometry for all sources. Extensive validation shows that Gaia DR1 represents a major advance in the mapping of the heavens and the availability of basic stellar data that underpin observational astrophysics. Nevertheless, the very preliminary nature of this first Gaia data release does lead to a number of important limitations to the data quality which should be carefully considered before drawing conclusions from the data

    Feel it in my bones: Composing multimodal experience through tissue conduction

    Get PDF
    We outline here the feasibility of coherently utilising tissue conduction for spatial audio and tactile input. Tissue conduction display-specific compositional concerns are discussed; it is hypothesised that the qualia available through this medium substantively differ from those for conventional artificial means of appealing to auditory spatial perception. The implications include that spatial music experienced in this manner constitutes a new kind of experience, and that the ground rules of composition are yet to be established. We refer to results from listening experiences with one hundred listeners in an unstructured attribute elicitation exercise, where prominent themes such as “strange”, “weird”, “positive”, “spatial” and “vibrations” emerged. We speculate on future directions aimed at taking maximal advantage of the principle of multimodal perception to broaden the informational bandwidth of the display system. Some implications for composition for hearing-impaired are elucidated.n/

    Measurement of charm production at central rapidity in proton-proton collisions at s=2.76\sqrt{s} = 2.76 TeV

    The pTp_{\rm T}-differential production cross sections of the prompt (B feed-down subtracted) charmed mesons D0^0, D+^+, and D+^{*+} in the rapidity range y<0.5|y|<0.5, and for transverse momentum 1<pT<121< p_{\rm T} <12 GeV/cc, were measured in proton-proton collisions at s=2.76\sqrt{s} = 2.76 TeV with the ALICE detector at the Large Hadron Collider. The analysis exploited the hadronic decays D0^0 \rightarrow Kπ\pi, D+^+ \rightarrow Kππ\pi\pi, D+^{*+} \rightarrow D0π^0\pi, and their charge conjugates, and was performed on a Lint=1.1L_{\rm int} = 1.1 nb1^{-1} event sample collected in 2011 with a minimum-bias trigger. The total charm production cross section at s=2.76\sqrt{s} = 2.76 TeV and at 7 TeV was evaluated by extrapolating to the full phase space the pTp_{\rm T}-differential production cross sections at s=2.76\sqrt{s} = 2.76 TeV and our previous measurements at s=7\sqrt{s} = 7 TeV. The results were compared to existing measurements and to perturbative-QCD calculations. The fraction of cdbar D mesons produced in a vector state was also determined.Comment: 20 pages, 5 captioned figures, 4 tables, authors from page 15, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/307
