Aim: To develop a process for returning medically actionable genomic variants to Latino patients receiving care in a Federally Qualified Health Center.
Methods: Prior to recruitment, researchers met with primary care providers to (1) orient clinicians to the project, (2) establish a process for returning actionable and nonactionable results to participants and providers through the electronic health record, and (3) develop a process for offering clinical decision support for follow-up education and care. A Community Advisory Board was engaged to provide input on recruitment strategies and materials for conveying results to participants. Read More

Sediments accumulation in reservoirs induces water storage capacities reduction and flood risks increases rendering dam flushing or dredging events compulsory for security reasons. Short transient events like dam flushing monitoring is still a great challenge because the suspended sediments and contaminants concentrations increases could occur over only few hours/days and cover tens of kilometres. Since 1942, 21 dam flushing events have been performed on the Upper Rhône River (from Lake Geneva in Switzerland to Lyon in France) in order to evacuate accumulated sediments behind the Verbois dam (Switzerland).

Metamaterials and metasurfaces provide unprecedented opportunities for designing light-matter interactions. Optical properties of hyperbolic metamaterials with meta-atoms based on plasmonic nanorods, important in nonlinear optics, sensing and spontaneous emission control, can be tuned by varying geometrical sizes and arrangement of the meta-atoms. At the same time the role of the shape of the meta-atoms forming the array has not been studied. Read More

Background: Asthma exacerbations affect the quality of life of patients with asthma and have a major effect on the overall costs of asthma care. An asthma self-management plan that advises the temporary quadrupling of inhaled corticosteroid dose may prevent asthma exacerbations, but this needs to be confirmed before being adopted widely.
Objectives: To compare the clinical effectiveness and cost-effectiveness of an asthma self-management plan that advises patients to temporarily quadruple the dose of inhaled corticosteroid when asthma control starts to deteriorate with a standard self-management plan. Read More

Plasmonic oligomers are one class of the most promising nanoclusters for generating Fano resonances. This study reveals that a nanobar-based heptamer concurrently sustains triple polarization-dependent Fano resonances, in sharp contrast to traditional nanodisk or nanosphere-based counterparts. Benefiting from the enhanced near field and reduced spectral linewidth, the gold heptamer exhibits a high refractive index sensitivity (940 nm per RIU) together with a figure of merit (FoM) value as large as 20.

Objective: The ability to modulate neural activity in a closed-loop fashion enables causal tests of hypotheses which link dynamically-changing neural circuits to specific behavioral functions. One such dynamically-changing neural circuit is the hippocampus, in which momentary sharp-wave ripple (SWR) events-≈ 100 ms periods of large 150-250 Hz oscillations-have been linked to specific mnemonic functions via selective closed-loop perturbation. The limited duration of SWR means that the latency in systems used for closed-loop interaction is of significant consequence compared to other longer-lasting circuit states. Read More

Methods: Baseline serum from 282 RA patients who failed MTX monotherapy were screened for the presence of anti-PAD4 antibodies by immunoprecipitation. Clinical response to either triple DMARD (MTX, sulfasalazine, and hydroxychloroquine) or MTX-etanercept combination therapy was determined at 24- and 48-weeks post-treatment initiation. Read More

We address the behavior in which a bias voltage can be used to switch on and off the photoluminescence of a planar film of methylammonium lead triiodide perovskite (MAPbI) semiconductor with lateral symmetric electrodes. It is observed that a dark region advances from the positive electrode at a slow velocity of order of 10 μm s. Here we explain the existence of the sharp front by a drift of ionic vacancies limited by local saturation, that induce defects and drastically reduce the radiative recombination rate in the film.

Sliding wear is particularly problematic for micro- and nano-scale devices and applications, and is often studied at the small scale to develop practical and fundamental insights. While many methods exist to measure and quantify the wear of a sliding atomic force microscope (AFM) probe, many of these rely on specialized equipment and/or assumptions from continuum mechanics. Here we present a methodology that enables simple, purely AFM-based measurement of wear, in cases where the AFM probe wears to a flat plateau. Read More

Traumatic insemination (TI) is an extraordinary style of mating behavior wherein the female integument is pierced by the male extragenital structure to transfer the spermatozoa into the female's body through wounding. Flower bugs of the genus Orius belong to the family Anthocoridae (Heteroptera), which is referred to as the "TI family". Males possess sharp shaped extragenitalia, and females receive the extragenitalia using the copulatory tubes, which are specialized extragenital structures in Orius species. Read More

While the transformation of carbon monoxide to multicarbon compounds (fuels and organic bulk chemicals) via reductive scission of the enormously strong CO bond is dominated by transition-metals, splitting and deoxygenative reductive coupling of CO under nonmatrix conditions using silicon, the second most abundant nonmetal of the Earth's crust, is extremely scarce and mechanistically not well understood. Herein we report the selective deoxygena-tive homocoupling of carbon monoxide by divalent silicon utilizing the (LSi:)2Xant 1a (Xant = 9,9-dimethyl-xanthene-4,5-diyl; L = PhC(NtBu)2) and (LSi:)2Fc 1b (Fc = 1,1'-ferrocenyl) as four-electron reduction reagents under mild reaction conditions (RT, 1 atm), affording the corresponding disilylketenes, Xant(LSi)2(µ-O)(µ-CCO) 2a and Fc(LSi)2(µ-O)(µ-CCO) 2b, respectively. However, the dibenzofuran analogue of 1b, compound 1c, was unreactive towards CO due to the longer distance between the two SiII atoms, which demonstrated the crucial role of the Si∙∙∙Si distance on cooperative CO binding and activation.

The tip-enhanced Raman spectroscopy (TERS) imaging technique is designed to provide correlated morphological and chemical information with a nanoscale spatial resolution by utilizing the plasmonic resonance supported by metallic nanostructures at the tip apex of a scanning probe. However, limited by the scattering cross-sections of these nanostructures, only a small fraction of the incident light can be coupled to the plasmonic resonance to generate Raman signals. The uncoupled light then directly excites background spectra with a diffraction-limited resolution, which becomes the background noise that often blurs the TERS image. Read More

A full comparison of results from binding isotherms and surface tension (ST) measurements on polyelectrolyte (PE)-surfactant (S) mixtures, especially the polymer dependence, shows up clear distinctions between the behaviour of two representative PE-S systems, poly(sodium styrenesulfonate) (NaPSS) with dodecyltrimethylammonium bromide (CTAB) and poly(dimethyl-diallyl-ammonium chloride) (PDMDAAC) with sodium dodecylsulfate (SDS) in 100 mM NaCl. The surfactant-monomer binding constant in NaPSS-CTAB is an order of magnitude greater than that in the PDMDAAC-SDS system. This results in the ST behaviour being dominated largely by non-cooperativity in the former and by cooperativity in the latter. Read More
