Ball lightning is widely concerning because it is hard to detect, predict, and reproduce. The dependences of electromagnetic (EM) solitons, which are considered expectant ball lightning, forming at the wavelength of the incident light are investigated wit
The incidence of nonmelanoma skin cancer is rising worldwide. The major carcinogenic factor for most skin cancers is solar ultraviolet light, in particular, the chronic exposure to UVB (280–320 nm). In this study, the optical characteristics of skin cance
亚运期间利用多轴差分吸收光谱仪(MAX-DOAS)对广州市的大气污染物进行了实时监测,分别对重要大 气常规污染物NO2和SO2的日变化特征进行了探讨和分析,并通过结合气象条件和周围的重要污 染源综合监测结果分析研究了广州市周围的区域污染输送,结果发现位于市东南部的工业区对于市区的 污染存在较大的影响,其中以SO2尤为明显。分析NO2廓线结果表明,污染物主要位于1 km以下,高污染 层主要位于0.5 km以下。
为了提高多自由度扫描三维拼接的稳定性，提出一种用于实时三维测量拼接的标志点高速、高稳定匹配方法。该方法综合考虑标志点间的距离关系、标志点与其周围标志点间的空间分布关系，提出标志点空间能量概念，实现了当前标志点的唯一性描述，从而利用能量唯一最大的特性实现多视角间的特征点匹配和三维拼接，有效解决了传统方法普遍存在的匹配歧义性问题。实验统计数据表明，两视角间匹配时间平均小于2 ms，正确率接近100%，满足多视角实时三维测量的应用需求。
A high-effective bottom anode is essential for high-performance top-emitting organic light-emitting devices (OLEDs). In this paper, Ag-based top-emitting OLEDs are investigated. Ag has the highest reflectivity for visible light among all metals, yet its h

Total curvature (TC) model and its alternating direction method of multipliers algorithm for noise r
This paper develops a variational model for image noise removal using total curvature (TC), which is a high-order regularizer. The TC has the advantage of preserving image feature. Unfortunately, it also has the characteristics of nonlinear, non-convex an
