Health systems that standardize their EHRs and that own and manage hospitals and medical groups have higher rates of advanced HIT adoption and use. System leaders looking to increase the use of advanced HIT capabilities should consider ways to better standardize their EHRs across organizations.
An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures.
Este articulo responde a la edicion especial de Qualitative Sociology (V. 20; N° 3; verano del 2005) dedicado al libro Body and Soul: Notebooks of an Apprentice Boxer [Entre las cuerdas. Cuadernos de un 1 aprendiz de boxeador]. Cuatro temas son tratados: el posicionamiento del investigador y la cuestion de la aceptacion social y de la pertenencia; la dinamica de la corporizacion y el rol variable de la raza como una propiedad estructural, interactiva y dispocisional; el funcionamiento del gimnasio donde se practica boxeo como una maquina civilizadora y masculinizadora en miniatura, junto con el enigma de las “mujeres ausentes”; y, finalmente, el aprendizaje como un modo de transmision de conocimiento y tecnica para la investigacion social, el area de la sociologia carnal, y el trabajo textual necesario para transmitir la textura multicolor y el encanto del mundo social. Esto nos lleva a clarificar la constitucion empirica, retorica y conceptual de Entre las cuerdas... en relacion a su triple intento de elucidar los trabajos de una competencia sociocultural que reside en las capacidades pre-discursivas; el desplegar y desarrollar el concepto de habitus como una filosofia operativa de la accion y guia metodologica; y ofrecer un informe, no para la sociologia del cuerpo (como un producto social e inteligible) sino para una sociologia desde el cuerpo (como florecimiento social y vector de conocimiento), ejemplificando una manera distintiva de hacer y escribir etnografia, que reconoce y toma una gran ventaja epistemica de la naturaleza visceral de la vida social.
Clouds and aerosols alter the proportion of diffuse radiation in global solar radiation reaching the Earth's surface. It is known that diffuse and direct beam radiation differ in the way they transfer through plant canopies and affect the summation of nonlinear processes like photosynthesis differently than what would occur at the leaf scale. We compared the relative efficiencies of canopy photosynthesis to diffuse and direct photosynthetically active radiation (PAR) for a Scots pine forest, an aspen forest, a mixed deciduous forest, a tallgrass prairie and a winter wheat crop. The comparison was based on the seasonal patterns of the parameters that define the canopy photosynthetic responses to diffuse PAR and those that define the responses to direct PAR. These parameters were inferred from half‐hourly tower CO 2 flux measurements. We found that: (1) diffuse radiation results in higher light use efficiencies by plant canopies; (2) diffuse radiation has much less tendency to cause canopy photosynthetic saturation; (3) the advantages of diffuse radiation over direct radiation increase with radiation level; (4) temperature as well as vapor pressure deficit can cause different responses in diffuse and direct canopy photosynthesis, indicating that their impacts on terrestrial ecosystem carbon assimilation may depend on radiation regimes and thus sky conditions. These findings call for different treatments of diffuse and direct radiation in models of global primary production, and studies of the roles of clouds and aerosols in global carbon cycle.
We report a highly diastereo- and enantioselective allylation of azlactones catalyzed by the combination of a metallacyclic iridium complex and an optically inactive phosphate anion. The process demonstrates an approach for conducting diastereoselective reactions with prochiral nucleophiles in the presence of metallacyclic allyliridium complexes. The reaction provides access to an array of enantioenriched allylated azlactones containing adjacent tertiary and quaternary carbon centers. Preliminary mechanistic studies suggest that the phosphate and methyl carbonate anions together induce the unusually high diastereoselectivity.
Abstract A simple method for the difluoromethylation of phenols and thiophenols using a non‐ozone‐depleting reagent is described.
Summary form only given. Because escape probability is about 2% per radiating surface, it is a good idea to use all six emitting surfaces of a solid rectangular LED. We introduce a photonic gas model for modelling this type of LED. Light extraction efficiency in thick (250/spl times/250/spl times/250 /spl mu/m) transparent substrate LED is a result of competition of light escape from the semiconductor chip, reabsorption in the active layer, and free-carrier absorption in the bulk. This modelling is confirmed by Monte Carlo simulations.
New cellular neural network chips, with stored-program capability and analog-and-logic architecture, are poised to challenge all-digital processing. In this article, we highlight the key ideas leading to the CNN Universal Machine, using simple circuit interpretations. We also illustrate the system, software, and application aspects.
Achirale Polysiloxane mit para ‐Alkoxybenzoesäure‐Seitengruppen können über Wasserstoffbrückenbindungen viele Moleküle eines optisch aktiven trans ‐Stilbazols binden. Das durch Selbstorganisation resultierende System 1 zeigt ferroelektrische Eigenschaften, die sich über die Zahl der Stilbazoleinheiten pro Polymermolekül und die Länge der (CH 2 ) n ‐Spacer steuern lassen. magnified image
