Abstract Four hundred myopic children randomly received atropine 0.02% (n = 138) or 0.01% 142) in both eyes once-nightly only wore single-vision spectacles (control group) 120) for 2 years. Spherical equivalent refractive error (SER), axial length (AL), pupil diameter (PD), and amplitude of accommodation (AMP) were measured every 4 months. After years, the SER changes − 0.80 (0.52) D, 0.93 (0.59) D 1.33 (0.72) AL 0.62 (0.29) mm, 0.72 (0.31) mm 0.88 (0.35) groups control group, respectively....

Corneal neovascularization (CRNV) is a prevalence eye disorder that affects the transparency and refraction properties of eyes. To explore correlation between level Angiotensin II (Ang II) corneal angiogenesis, rat model CRNV was established using alkali-burn, while human umbilical vein endothelial cells (HUVECs) were stimulated VEGF to induce in vitro. RNA immunoprecipitation (RIP) pull-down performed validate relationship MIAT miR-1246. The expression Ang increased, miR-1246 decreased...
The indium tin oxide (ITO) thin film plays an important role in the silicon heterojunction (SHJ) solar cells, which acts as not only a carrier transport layer vertical and lateral directions but anti-reflection well. Thickness reduction of expensive ITO is efficient strategy to reduce cost SHJ cells. In this work, simulated antireflection effects several dielectric capping layers demonstrate that Al 2 O 3 SiO are suitable candidates for both cell module. Hall effect measurements show able...

Abstract The traffic flow prediction is the key to alleviate congestion, yet very challenging due complex influence factors. Currently, most of deep learning models are designed dig out intricate dependency in continuous standardized sequences, which dependent high requirements for data continuity and regularized distribution. However, discontinuity irregular distribution inevitable real-world practical application, then we need find a way utilize powerful effect multi-feature fusion rather...
As an important part of urban big data, traffic flow data play a critical role in management and emergency response. Traffic contain multi-mode characteristics, which need to be deeply mined. To make full use we 3-order tensor represent the considering “temporal-spatial-periodic” characteristics. recover missing flow, propose Missing Data Completion Algorithm Based on Residual Value Tensor Decomposition (MDCA-RVTD), combines linear regression, univariate spline, CP decomposition. Then,...

Most electrostatic actuators fabricated by MEMS technologies require high actuation voltage and suffer from the pull-in phenomenon in presence of parasitic capacitance, either driven conventional control or charge control. The resonant drive circuit presented this paper uses much lower supply to actuators, which usually a amplifier, through passive amplification at its electrical resonance. Furthermore, it is shown that able extend operation range beyond point even capacitance due inherent...
