    Entanglement sharing in E⊗ϵE\otimes\epsilon Jahn-Teller model in the presence of a magnetic field

    Full text link
    We discuss the ground state entanglement of the E⊗ϵE\otimes\epsilon Jahn-Teller model in the presence of a strong transverse magnetic field as a function of the vibronic coupling strength. A complete characterization is given of the phenomenon of entanglement sharing in a system composed by a qubit coupled to two bosonic modes. Using the residual II-tangle, we find that three-partite entanglement is significantly present in the system in the parameter region near the bifurcation point of the corresponding classical model

    Archaeologically Defining the Earlier Garden Landscapes at Morven: Preliminary Results

    The first phase of archaeology at Morven was designed to test the potential for further study of the early garden landscape at a ca. 1758 house in Princeton, New Jersey. The research included intensive botanical analysis using a variety of archaeobotanical framework. A study was also made of the garden\u27s topography using map analysis combined with subsurface testing. Information on garden features related to the design of earlier garden surfaces suggests the ways in which the Stockton family manipulated their estate to convey a social image of the family to the local Princeton community. This, in turn, provides information that, when combined with collateral ethnographic information obtained from documents, suggests the symbolic content of the garden

    The first phase of archaeology at Morven was designed to test the potential for further study of the early garden landscape at a ca. 1758 house in Princeton, New jersey. The research included intensive botanical analysis using a variety of archaeobotanical techniques integrated within a broader ethnobotanical framework. A study was also made of the garden\u27s topography using map analysis combined with subsurface testing. Information on garden features related to the design of earlier garden surfaces suggests the ways in which the Stockton family manipulated their estate to convey a social image of the family to the local Princeton community.

    Performance of the PADME calorimeter prototype at the DAΦ\PhiNE BTF

    The PADME experiment at the DAΦ\PhiNE Beam-Test Facility (BTF) aims at searching for invisible decays of the dark photon by measuring the final state missing mass in the process e+e−→γ+A′e^+e^- \to \gamma+ A', with A′A' undetected. The measurement requires the determination of the 4-momentum of the recoil photon, performed using a homogeneous, highly segmented BGO crystals calorimeter. We report the results of the test of a 5×\times5 crystals prototype performed with an electron beam at the BTF in July 2016

    Screening of respiratory pathogens by Respiratory Multi Well System (MWS) r-geneâ„¢ assay in hospitalized patients

    Novel respiratory viruses have been identified as possible agents of upper and lower respiratory tract infections. Multiplex real-time PCRs have been developed to identify clinically relevant respiratory pathogens. In this study, 178 respiratory samples already screened for influenza virus types A and B by Flu A/B ASR real-time PCR kit were retrospectively analyzed with the Respiratory Multi Well System (MWS) r-geneâ„¢ real-time PCR kit which detects a wide spectrum of respiratory pathogens. The goal was to demonstrate the importance of a wide spectrum screening compared to a single diagnostic request. The Flu A/B ASR kit detected influenza B virus in 1.7% of the samples (3/178) and no influenza A virus. The MWS r-geneâ„¢ kit detected influenza virus in 6.7% (12/178) of samples (0.6% influenza A, and 6.2% influenza B), while the overall detection rate for respiratory pathogens was 54% (96/178). Co-infections were detected in 8/178 (4.5%) samples. Adenovirus was the infectious agent detected most frequently, followed by respiratory syncytial virus. The risk of being infected by respiratory syncytial virus is almost threefold higher in patients older than 65 years compared to the younger age group (OR:2.7, 95% CI: 1.2-6.2). Wide spectrum screening of respiratory pathogens by real-time PCR is an effective means of detecting clinically relevant viral pathogens
