    This report is part of a series of 21 state and regional studies examining the rollout of the ACA. The national network -- with 36 states and 61 researchers -- is led by the Rockefeller Institute of Government, the public policy research arm of the State University of New York, the Brookings Institution, and the Fels Institute of Government at the University of Pennsylvania.New Mexico is no longer one of the key battleground states as it has moved more Democratic in recent presidential races, a trend driven by Latino population growth and a shift to the Democratic Party among that population. During the 2013 legislative session, Senate Bill 221 passed and authorized the establishment of a state-run New Mexico Health Insurance Exchange (NMHIX). On March 28, 2013, the governor signed Senate Bill 221 into law. Another major ACA-related decision involved Medicaid. Given the aggressive opposition from other Republican governors to the ACA, Martínez surprised some observers when she announced in early 2013 that New Mexico would expand Medicaid as long as the federal government provided the funding for the initial expansion

    Considerando la alta incidencia de vulvovaginitis en la consulta de ginecología pediátrica y de adolescentes, y los aspectos únicos de la microbiología y endocrinología de la paciente prepúber se presenta una revisión de la literatura con lo más relevante de los últimos 5 años, en lo que se refiere a epidemiología, etiología, diagnóstico y tratamiento de la vulvovaginitis bacteriana específica de la niña prepúber. No existe claridad acerca de la microflora vaginal normal, lo cual dificulta en gran medida la interpretación de muestras. De acuerdo con la evidencia actual podemos decir que ante la vulvovaginitis específica de la prepúber debemos tener en consideración como principales agentes causales: patógenos respiratorios, epidérmicos y entéricos; higiene defectuosa, cuerpos extraños, irritantes, enfermedades dermatológicas vulvares, defectos anatómicos y abuso sexual. Streptococcus hemolitico del grupo A y Haemophilus influenzae son patógenos prevalente

    Kerker Conditions Upon Lossless, Absorption, and Optical Gain Regimes

    The directionality and polarization of light show peculiar properties when the scattering by a dielectric sphere can be described exclusively by electric and magnetic dipolar modes. Particularly, when these modes oscillate in-phase with equal amplitude, at the so-called first Kerker condition, the zero optical backscattering condition emerges for non-dissipating spheres. However, the role of absorption and optical gain in the first Kerker condition remains unexplored. In this work, we demonstrate that either absorption or optical gain precludes the first Kerker condition and, hence, the absence of backscattered radiation light, regardless of the size of the particle, incident wavelength, and incoming polarization. Finally, we derive the necessary prerequisites of the second Kerker condition of the zero forward light scattering, finding that optical gain is a compulsory requirement

    Search for photospheric footpoints of quiet Sun transition region loops

    Full text link
    CONTEXT:The footpoints of quiet Sun Transition Region (TR) loops do not seem to coincide with the photospheric magnetic structures appearing in traditional low-sensitivity magnetograms. AIMS: To look for the so-far unidentified photospheric footpoints of TR loops using G-band bright points (BPs) as proxies for photospheric magnetic field concentrations. METHODS: Comparison of TR measurements with SoHO/SUMER and photospheric magnetic field observations obtained with the Dutch Open Telescope. RESULTS: Photospheric BPs are associated with bright TR structures, but they seem to avoid the brightest parts of the structure. BPs appear in regions that are globally redshifted, but they avoid extreme velocities. TR explosive events are not clearly associated with BPs. CONCLUSIONS: The observations are not inconsistent with the BPs being footpoints of TR loops, although we have not succeeded to uniquely identify particular BPs with specific TR loops.Comment: Accepted for publication in A&A. 10 pages, 10 figures.

    Cultural macroevolution of musical instruments in South America

    Musical instruments provide material evidence to study the diversity and technical innovation of music in space and time. We employed a cultural evolutionary perspective to analyse organological data and their relation to language groups and population history in South America, a unique and complex geographic area for human evolution. The ethnological and archaeological native musical instrument record, documented in three newly assembled continental databases, reveals exceptionally high diversity of wind instruments. We explored similarities in the collection of instruments for each population, considering geographic patterns and focusing on groupings associated with language families. A network analysis of panpipe organological features illustrates four regional/cultural clusters: two in the Tropical Forest and two in the Andes. Twenty-five percent of the instruments in the standard organological classification are present in the archaeological, but not in the ethnographic record, suggesting extinction events. Most recent extinctions can be traced back to European contact, causing a reduction in indigenous cultural diversity

    Phylogeny of the Grasses (Poaceae) Revisited

    The most robust previously published phylogeny for the overall structure of the grass family (Poaceae) shows three early diverging lineages and two major derived clades, the BEP clade and the PACCAD clade (Grass Phylogeny Working Group 2001). A few key taxa were incompletely sampled, however, and support for the BEP clade was moderate at best and relationships among the major lineages within the PACCAD clade remained unresolved. In addition, recent studies indicated that the sister group to Poaceae may be Joinvilleaceae and/or Ecdeiocoleaceae, the latter of which were not previously sampled. In this study, missing structural data were determined and analyzed as well as sequence data for ndhF and rbcL, the two most complete plastid sequence data sets. Sampling was increased with a particular focus on key taxa such as Danthoniopsis, Eriachne, Micraira, and Streptogyna and a representative of the outgroup, Ecdeiocoleaceae. A total of 61 ingroup and two outgroup taxa were analyzed using maximum parsimony for total data, and maximum parsimony, Bayesian inference, and neighbor joining for the molecular data. A strongly supported clade of ((Eriachneae, Isachne) Micraira) was recovered as a sister subfamily to Arundinoideae and excluded from Panicoideae. Arundinaria was strongly united with Bambusoideae. The position of Streptogyna was weakly supported among Ehrhartoideae, and is still unresolved. An outgroup effect on ingroup topology was observed, demonstrating that highly divergent outgroups may unpredictably alter ingroup relationships

    What drives growth of Scots pine in continental Mediterranean climates: drought, low temperatures or both?

    Scots pine forests subjected to continental Mediterranean climates undergo cold winter temperatures and drought stress. Recent climatic trends towards warmer and drier conditions across the Mediterranean Basin might render some of these pine populations more vulnerable to drought-induced growth decline at the Southernmost limit of the species distribution. We investigated how cold winters and dry growing seasons drive the radial growth of Scots pine subject to continental Mediterranean climates by relating growth to climate variables at local (elevational gradient) and regional (latitudinal gradient) scales. Local climate-growth relationships were quantified on different time scales (5-, 10- and 15-days) to evaluate the relative role of elevation and specific site characteristics. A negative water balance driven by high maximum temperatures in June (low-elevation sites) and July (high-elevation sites) was the major constraint on growth, particularly on a 5- to 10-day time scale. Warm nocturnal conditions in January were associated with wider rings at the high-elevation sites. At the regional scale, Scots pine growth mainly responded positively to July precipitation, with a stronger association at lower elevations and higher latitudes. January minimum temperatures showed similar patterns but played a secondary role as a driver of tree growth. The balance between positive and negative effects of summer precipitation and winter temperature on radial growth depends on elevation and latitude, with low-elevation populations being more prone to suffer drought and heat stress; whereas, high-elevation populations may be favoured by warmer winter conditions. This negative impact of summer heat and drought has increased during the past decades. This interaction between climate and site conditions and local adaptations is therefore decisive for the future performance and persistence of Scots pine populations in continental Mediterranean climates. Forecasting changes in the Scots pine range due to climate change should include this site-related information to obtain more realistic predictions, particularly in Mediterranean rear-edge areas

    Engineering bound states in the continuum at telecom wavelengths with non-Bravais lattices

    Get PDF
    Various optical phenomena can be induced in periodic arrays of nanoparticles by the radiative coupling of the local dipoles in each particle. Probably the most impressive example is bound states in the continuum (BICs), which are electromagnetic modes with a dispersion inside the light cone but infinite lifetime, i.e., modes that cannot leak to the continuum. Symmetry-protected BICs appear at highly symmetric points in the dispersion of periodic systems. Although the addition of nonequivalent lattice points in a unit cell is an easy and straightforward way of tuning the symmetry, BICs in such particle lattice, i.e., non-Bravais lattice, are less explored among periodic systems. Starting from a periodic square lattice of Si nanodisks, we have prepared three non-Bravais lattices by detuning size and position of the second disk in the unit cell. Diffraction-induced coupling excites magnetic/electric dipoles in each nanodisk, producing two surface lattice resonances at the Γ\Gamma point with a band gap in between. %of ∼\sim 41 meV. The high/low energy branch becomes a BIC for the size/position-detuned array, respectively, while both branches are bright (or leaky) when both size and position are detuned simultaneously. The role of magnetic and electric resonances in dielectric nanoparticles and the change of BIC to bright character of the modes is explained by the two different origins of BICs in the detuned arrays, which is further discussed with the aid of a coupled electric and magnetic dipole model. This study gives a simple way of tuning BICs at telecom wavelengths in non-Bravais lattices, including both plasmonic and dielectric systems, thus scalable to a wide range of frequencies.Comment: 26 pages, 5 figure
