Counties with higher poverty levels had a significantly elevated rate of CWP (adjusted rate ratios [RR] 1.15; 95% CI, 1.12-1.18). There was a small but significant association of CWP with the county-wise catchment area. Rurality was associated with a more than three-fold elevated rate of CWP in the unadjusted analysis (RR 3.28, 95% CI, 2.22-4.84). Orludodstat price However, the rate declined to 1.45 (95% CI, 1.04-2.01) after adjusting for other factors in the analysis. CONCLUSIONS We found evidence of significant spatial clustering of CWP among Medicare beneficiaries living in the seven states of the USA. © 2020 Wiley Periodicals, Inc.For many years, the dominant theoretical framework guiding research into the neural origins of perceptual experience has been provided by hierarchical feedforward models, in which sensory inputs are passed through a series of increasingly complex feature detectors. However, the long-standing orthodoxy of these accounts has recently been challenged by a radically different set of theories that contend that perception arises from a purely inferential process supported by two distinct classes of neurons those that transmit predictions about sensory states and those that signal sensory information that deviates from those predictions. Although these predictive processing (PP) models have become increasingly influential in cognitive neuroscience, they are also criticized for lacking the empirical support to justify their status. This limited evidence base partly reflects the considerable methodological challenges that are presented when trying to test the unique predictions of these models. However, a confluence of technological and theoretical advances has prompted a recent surge in human and nonhuman neurophysiological research seeking to fill this empirical gap. Here, we will review this new research and evaluate the degree to which its findings support the key claims of PP. © 2020 The Authors.

We review two Adaptive Optics set-ups implemented at the Visual Optics and Biophotonics Laboratory, and present examples of their use in better understanding of the role of optical aberrations on visual perception, in normal and treated eyes. RECENT FINDINGS Two systems (AOI and AOII) are described that measure ocular aberrations with a Hartmann-Shack wavefront sensor, which operates in closed-loop with an electromagnetic deformable mirror, and visual stimuli are projected in a visual display for psychophysical measurements. AOI operates in infrared radiation (IR) light. AOII is provided with a supercontiniuum laser source (IR and visible wavelengths), additional elements for simulation (spatial light modulator, temporal multiplexing with optotunable lenses, phase plates, cuvette for intraocular lenses-IOLs), and a double-pass retinal camera. We review several studies undertaken with these AO systems, including © 2020 The College of Optometrists.The poor stability of perovskite light-emitting diodes (PeLEDs) is a key bottleneck that hinders commercialization of this technology. Here, the degradation process of formamidinium lead iodide (FAPbI3 )-based PeLEDs is carefully investigated and the device stability is improved through binary-alkalication incorporation. Using time-of-flight secondary-ion mass spectrometry, it is found that the degradation of FAPbI3 -based PeLEDs during operation is directly associated with ion migration, and incorporation of binary alkali cations, i.e., Cs+ and Rb+ , in FAPbI3 can suppress ion migration and significantly enhance the lifetime of PeLEDs. Combining experimental and theoretical approaches, it is further revealed that Cs+ and Rb+ ions stabilize the perovskite films by locating at different lattice positions, with Cs+ ions present relatively uniformly throughout the bulk perovskite, while Rb+ ions are found preferentially on the surface and grain boundaries. Further chemical bonding analysis shows that both Cs+ and Rb+ ions raise the net atomic charge of the surrounding I anions, leading to stronger Coulomb interactions between the cations and the inorganic framework. As a result, the Cs+ -Rb+ -incorporated PeLEDs exhibit an external quantum efficiency of 15.84%, the highest among alkali cation-incorporated FAPbI3 devices. More importantly, the PeLEDs show significantly enhanced operation stability, achieving a half-lifetime over 3600 min. © 2020 The Authors. Published by WILEY-VCH Verlag GmbH & Co.

In this study, we identified and characterized the bacterium by genome analysis, biochemical properties and pathogenicity. The bacterium was a Gram-negative, non-motile, long rod, forming yellow colonies on a marine agar plate. It grew at 20-33°C (not at 37°C) and degraded chitin and gelatin. Phylogenetic analysis of the 16S rRNA gene sequence identified the bacterium as Aquimarina hainanensis. Genome sequence data obtained from Illumina MiSeq generated 29 contigs with 3.56 Mbp in total length and a G + C content of 32.5%. The predicted 16 chitinase genes, as putative virulence factors, had certain homologies with those of genus Aquimarina. Experimental infection with the bacterium conducted on larvae of four crustacean species, brine shrimp Artemia franciscana, freshwater shrimp Caridina multidentata, swimming crab Portunus trituberculatus and mud crab S. serrata, revealed that this bacterium was highly virulent to these species. The present study suggests that the bacterium caused mass mortality in mud crab seed production was A. hainanensis and can be widely pathogenic to crustaceans. © 2020 John Wiley & Sons Ltd.BACKGROUND AND OBJECTIVES Radiofrequency (RF)-induced ablation can be carried out inside ducts and vessels by simultaneously dragging a bipolar catheter while applying RF power. Our objective was to characterize the relation between pullback speed, impedance progress, and temperature distribution. STUDY DESIGN/MATERIALS AND METHODS We built a numerical model including a bipolar catheter, which is dragged inside a duct while RF power is applied between a pair of electrodes. The model solved a triple-coupled electrical, thermal, and mechanical problem. Lesions were assessed by an Arrhenius model. The numerical model’s thermal and electrical characteristics were chosen to obtain the same initial impedance value as in the experiments 560 Ω at 16°C (sample temperature). RESULTS The catheter initially remained still, and the impedance was falling during the application of power. When pullback speed was too slow ( less then 0.4 mm/s) impedance continued to drop when the catheter began to move, creating deep lesions, overheating and impedance roll-off, while at the faster speed (0.
