Recently, disordered metasurfaces have attracted considerable interest due to their potential applications in imaging, holography, and wavefront shaping. However, how emerge long-range ordered phase distribution remains an outstanding problem. Here, a general framework is proposed generate spatially homogeneous in-plane from metasurface, by engineering disorder parameters together with topology optimization. As proof-of-concept demonstration, all-dielectric supercell metasurface relatively...
Dispersion decomposes compound light into its monochromatic components, which is detrimental to broadband imaging but advantageous for spectroscopic applications. Metasurfaces provide a unique path modulate the dispersion by adjusting structural parameters on two-dimensional plane. However, conventional linear phase compensation does not adequately match meta-unit's characteristics with required complex dispersion, hindering at-will engineering over very wide bandwidth particularly. Here, we...
To distinguish malignant cervical lymphadenopathy, we established a new scoring system based on ultrasound features. Two hundred sixty-three patients with lymphadenopathy received ultrasonic examination and underwent ultrasound-guided core needle biopsy or fine aspiration. The was proposed by multivariate logistic regression analysis compared Liao (0.06 × age + 4.76 shortest-to-longest axis ratio 2.15 internal echo 1.80 vascular pattern). A model, 1.346 margin 1.339 hilum 2.411 calcification...
Abstract Dispersion decomposes compound light into monochromatic components at different spatial locations, which needs to be eliminated in imaging but utilized spectral detection. Metasurfaces provide a unique path modulate the dispersion by adjusting structural parameters without changing material as required for refractive elements. However, common linear phase compensation does not conform characteristics of meta-unit, limits modulation broader wavelength bands. Here, we propose...
Epilepsia é uma condição neurológica crônica prevalente e, apesar do tratamento adequado controlar aproximadamente 70% dos casos, muito comum, ainda nos dias de hoje, ouvirmos mitos e crenças sobre epilepsia. Para reverter esta situação, o Projeto Demonstrativo da Campanha Global " fora das sombras" , OMS/ILAE/IBE, trouxe mudanças importantes em nossa sociedade, entre elas engajamento associações epilepsia nosso país. Uma atividades deste movimento nacional a realização Semana Nacional...
A novel miniaturized ultra-wide bandwidth (DC–35 GHz) LC phase delay line (PDL) based on overlapped meander inductors and air-bridge capacitors is proposed fabricated. Two 45º 90º PDLs were designed using a semi-lumped model, the parameters calculated optimized transmission theory 3D simulations. The lengths of lines are 110 μm 286 μm, respectively, which represent respective length reductions 50% 75% when compared with corresponding conventional lines. Over entire operating band, error less...
Abstract To assess the diagnostic performance of quantitative parameters for virtual touch tissue imaging quantification by mechanical arm probe, 128 women with 152 breast lesions (90 benign and 62 malignant) were included maximum elasticity ( V max ), median mean minus minimum max-min min ) measured. Intercorrelation coefficients Bland-Altman plots used to compare repeatability consistency handheld probe measurements. Receiver operating characteristic curve was evaluate efficiency. The...
Apesar da epilepsia ser a condição neurológica grave mais comum existente no mundo, crenças e comportamentos inadequados ainda persistem. Para mudar esta perspectiva, o Projeto Demonstrativo Campanha Global "Epilepsia fora das sombras" permitiu engajamento associações de em nosso país, fortalecendo Movimento Nacional Epilepsia. Uma atividades deste movimento é realização Semana Conscientização Epilepsia, que acontece todos os anos na semana do dia 09 setembro, com objetivo conscientizar...
<p class="Abstract">The present study was aimed to investigate the effect of 18α-glycyrrhetinic acid on induction apoptosis and DNA-damage in HR5-CL11 cervical carcinoma cells. The results revealed 73.6% reduction cell viability treatment with 5 µM concentration for 48 hours. DNA acid-treated cells showed a ladder-like pattern. Fragmentation markedly higher compared control Examination damage after breakage strands formation comet-like structures. frequency comet treated found be 7.8...
