The dissolving technique of ionic liquid (IL) was applied in extraction process of hydroxyapatite (HAp). Product HAp was extracted by IL choline chloride-urea (ChCl-Urea) dissolving cattle bone. The optimum conditions for regeneration process of cattle bone were determined by single factor, orthogonal and verification experiments. IR spectra of regenerated bone, undissolved bone and raw bone showed that the main groups of regenerated bone did not change. It was indicated that ionic liquid did not damage the bone collagen of raw bone, and the collagen was only dissolved by IL. IR spectrum of the product HAp revealed that its components were similar to those of the natural bone. SEM pattern showed that the crystal shape of the product HAp appeared rod-like shape mostly, and the crystal structure was relatively complete. XRD diffraction explained that there was no difference between product HAp and standard HAp for the crystalline form and compositions.

The phase delay problem of invisibility cloaks designed by optical conformal mapping is referred to the optical path difference between the waves in upper and lower Riemann sheets. As the frequency changes, the phase delay varies accordingly (here, we call it geometrical dispersion), which restricts the cloaks to working only at some discrete frequencies. Here, we solve the phase-delay problem by placing an optically null medium in the lower Riemann sheet. The conformal cloaks designed by using our method have many advantages, such as a continuous working band (no geometrical dispersion), omnidirectionality, robustness under frequency shifts, and no need for any complex materials that are both anisotropic and inhomogeneous. We also design metallic microchannels to realize our cloaks.

This work focuses on the generation of far-field super-resolved pure-azimuthal focal field based on the fast Fourier transform. A self-designed differential filter is first pioneered to robustly reconfigure a doughnut-shaped azimuthal focal field into a bright one with a sub-wavelength lateral scale (∼0.392λ), which offers a 27.3% reduction ratio relative to that of tightly focused azimuthal polarization modulated by a spiral phase plate. By further uniting the versatile differential filter with spatially shifted beam approach, in addition to allowing for an extremely sharper focal spot, whose size is in turn reduced to 0.228λ and 0.286λ in the transverse as well as axial directions, the parasitic sidelobes are also lowered to an inessential level (3/128). The relevant phase profiles are further exhibited to unravel the annihilation of field singularity and locally linear (i.e. azimuthal) polarization. Our scheme opens a promising route toward efficiently steer and tailor the redistribution of the focal field. Copyright © 2019, The Authors. All rights reserved.

Background: Hearing loss affects access to spoken language, which can affect cognition and development, and can negatively affect social wellbeing. We present updated estimates from the Global Burden of Disease (GBD) study on the prevalence of hearing loss in 2019, as well as the condition's associated disability. Methods: We did systematic reviews of population-representative surveys on hearing loss prevalence from 1990 to 2019. We fitted nested meta-regression models for severity-specific prevalence, accounting for hearing aid coverage, cause, and the presence of tinnitus. We also forecasted the prevalence of hearing loss until 2050. Findings: An estimated 1·57 billion (95% uncertainty interval 1·51–1·64) people globally had hearing loss in 2019, accounting for one in five people (20·3% [19·5–21·1]). Of these, 403·3 million (357·3–449·5) people had hearing loss that was moderate or higher in severity after adjusting for hearing aid use, and 430·4 million (381·7–479·6) without adjustment. The largest number of people with moderate-to-complete hearing loss resided in the Western Pacific region (127·1 million people [112·3–142·6]). Of all people with a hearing impairment, 62·1% (60·2–63·9) were older than 50 years. The Healthcare Access and Quality (HAQ) Index explained 65·8% of the variation in national age-standardised rates of years lived with disability, because countries with a low HAQ Index had higher rates of years lived with disability. By 2050, a projected 2·45 billion (2·35–2·56) people will have hearing loss, a 56·1% (47·3–65·2) increase from 2019, despite stable age-standardised prevalence. Interpretation: As populations age, the number of people with hearing loss will increase. Interventions such as childhood screening, hearing aids, effective management of otitis media and meningitis, and cochlear implants have the potential to ameliorate this burden. Because the burden of moderate-to-complete hearing loss is concentrated in countries with low health-ca

Type 2 diabetes (T2D) is a heterogeneous disease that develops through diverse pathophysiological processes and molecular mechanisms that are often specific to cell type. Here, to characterize the genetic contribution to these processes across ancestry groups, we aggregate genome-wide association study data from 2,535,601 individuals (39.7% not of European ancestry), including 428,452 cases of T2D. We identify 1,289 independent association signals at genome-wide significance (P < 5 × 10) that map to 611 loci, of which 145 loci are, to our knowledge, previously unreported. We define eight non-overlapping clusters of T2D signals that are characterized by distinct profiles of cardiometabolic trait associations. These clusters are differentially enriched for cell-type-specific regions of open chromatin, including pancreatic islets, adipocytes, endothelial cells and enteroendocrine cells. We build cluster-specific partitioned polygenic scores in a further 279,552 individuals of diverse ancestry, including 30,288 cases of T2D, and test their association with T2D-related vascular outcomes. Cluster-specific partitioned polygenic scores are associated with coronary artery disease, peripheral artery disease and end-stage diabetic nephropathy across ancestry groups, highlighting the importance of obesity-related processes in the development of vascular outcomes. Our findings show the value of integrating multi-ancestry genome-wide association study data with single-cell epigenomics to disentangle the aetiological heterogeneity that drives the development and progression of T2D. This might offer a route to optimize global access to genetically informed diabetes care.

The abundance of carbon dioxide gas in the atmosphere raises concerns as it affects the environmental sustainability, human's wellbeing as well as the nature. The photocatalysis conversion of carbon dioxide produces valuable gas and limits environmental issue in the same time. Therefore, it attracts the attention to synthesize photocatalyst that is active under visible light irradiation since sunlight provides abundant photon energy mostly in visible light range. In this study, CdS as visible light-active photocatalyst is loaded with nickel to improve its performance to convert CO2 to methanol under irradiation of 500 W of Xe lamp as visible light source. The spherical nanoparticles morphology can be observed for synthesized CdS and Ni/CdS by using field emission scanning electron microscopy (FE-SEM) analysis. The yield of methanol was examined by using high performance liquid chromatography (HPLC). The result shows that the yield can be improved from 11 μmol/g-catalyst to 2348 μmol/g-catalyst by loading of 3wt% of nickel in CdS. The further loading of nickel decreased the yield of methanol.

Induction in Optimal control of Multiple-Kite Airborne Wind Energy systems

引用

IFAC-PapersOnLine 2017年第1期50卷 153-158页

作者： Leuthold R. Gros S. Diehl M. Systems Control and Optimization Laboratory Dept. of Microsystems Engineering Dept. of Mathematics University of Freiburg Germany Department of Signals and System Chalmers University Freiburg Institute for Advanced Studies Sweden

Multiple-kite Airborne Wind Energy systems (MAWES) aim to decrease inter-mittency and cost over conventional wind turbines, while generating more power than other airborne wind energy systems. The purpose of this work is to estimate whether axial and angular induction are relevant phenomena in the modelling of pumping-cycle MAWES with two or more kites. Considering the modelling assumptions, axial induction is a relevant phenomenon and leads to significant changes in design-point, especially with respect to kite mass and secondary tether length. However, angular induction can be neglected in modelling for optimal design and control problems. © 2017
