We propose theoretically and verify experimentally a method of combining q-plate spiral phase plate to generate arbitrary vector vortex beams on hybrid-order Poincare sphere. demonstrate that beam can be decomposed into vortex, whereby the generation realized by sequentially using plate. The generated beam, are verified show good agreement with prediction. Another advantage should pointed out is both fabricated silica substrates, suggesting potential possibility integrate two structures...
Perfect vortex beams are the orbital angular momentum (OAM)-carrying with fixed annular intensities, which provide a better source of OAM than traditional Laguerre- Gaussian beams. However, ordinary schemes to obtain perfect usually bulky and unstable. We demonstrate here novel generation scheme by designing planar Pancharatnam-Berry (PB) phase elements replace all required. Different from conventional approaches based on reflective or refractive elements, PB can dramatically reduce...
Accurate estimation of the state charge (SOC) batteries is one key problems in a battery management system. This paper proposes an adaptive SOC method based on unscented Kalman filter algorithms for lithium (Li)-ion batteries. First, enhanced model proposed to include impacts due different discharge rates and temperatures. An joint internal resistance then presented enhance system robustness with aging. The algorithm has been developed verified through experiments types Li-ion results...
The regeneration of metal sulfides during the delithiation process is key to achieving cyclic stability in electrode materials. A graphene-supported peony-like MoS2 nanocomposite with a long cycle life and high rate capability designed for this purpose. synergistic effects hierarchical structure graphene can effectively improve lithium diffusion dynamics conductivity, thus greatly suppressing oxidation Li2S polysulfides by improving reversibility conversion reaction. As service our authors...
Self-assembly of block copolymers (BCPs) has been developed as a promising approach for constructing photonic crystal (PC) microspheres dynamic optical modulation. However, high curvature in the center usually distorts periodic core structure, leading to an inconsistency bandgap and poor monochromaticity structural color. Herein, we report simple yet robust strategy fabricating responsive PC microcapsules polystyrene-b-poly(2-vinylpyridine) through self-emulsification strategy....

A novel opal closest‐packing (OCP) photonic crystal (PC) is successfully prepared for naked‐eye glucose detection. This PC fabricated via a vertical convective self‐assembly method with new type of monodisperse microsphere polymerized by co‐monomers, namely, methyl methacrylate (MMA), N‐isopropylacrylamide (NIPA), and 3‐acrylamidophenylboronic acid (AAPBA). The OCP has high stability periodically‐ordered structure, showing the desired structural color. proposed material displays red shift...
Super-Resolution (SR) is a fundamental computer vision task that aims to obtain high-resolution clean image from the given low-resolution counterpart. This paper reviews NTIRE 2021 Challenge on Video Super-Resolution. We present evaluation results two competition tracks as well proposed solutions. Track 1 develop conventional video SR methods focusing restoration quality. 2 assumes more challenging environment with lower frame rates, casting spatio-temporal problem. In each competition, 247...
As a computing accelerator, large-scale photonic spatial Ising machine has great advantages and potential due to its excellent scalability compactness. However, the current fundamental limitation of is configuration flexibility for problem implementation in accelerator model. Arbitrary spin interactions are highly desired solving various non-deterministic polynomial (NP)-hard problems. In this paper, we propose novel quadrature break through by synchronous phase manipulation two sections....
