On‐Chip Light Polarization Management by Mapping the Polarization Information to Phase Shift

Qingzhong Deng, Ming Jin, Jun Qin, Pengfei Sun, more

Laser & Photonics Reviews > 18 > 1 > n/a - n/a

The comprehensive management of light polarization states has significantly advanced various fields into a new era. With the advent of photonic integration, there has been a persistent desire to replace the bulky optical components with compact chip‐scale circuits. Nonetheless, the complete integration of polarization‐dependent systems has not yet been accomplished due to the absence of a mature polarization...

Yuan Chen, Baobao Sun, Haohui Feng, Ranran Wang, more

Chemistry – A European Journal > 27 > 48 > 12305 - 12309

Chirality at different levels is widely observed in nature, but the clue to connect it all together, and the way chirality transfers among different levels are still obscure. Herein, a l‐/d‐lysine‐based self‐assembly system was constructed, in which two‐step chirality transfer among three different levels was observed in aqueous solution. The chirality originated from the point chirality of amino...

An image retrieval method based on semantic matching with multiple positional representations

Chunye Li, Zhiping Zhou, Wei Zhang

Multimedia Tools and Applications > 2019 > 78 > 24 > 35607- 35631

Text-based image retrieval requires manual annotation or automatic labeling of the machine. Manual annotation is time-consuming, and simple text description is difficult to fully express the content of the image. Existing deep models rely on the representation of a single sentence, and such methods cannot well capture the contextualized local information in the matching process. In response to these...

Multi-target tracking by non-linear motion patterns based on hierarchical network flows

Weigang Lu, Zhiping Zhou, Lijuan Zhang, Guoqiang Zheng

Multimedia Systems > 2019 > 25 > 4 > 383-394

We propose a multi-target tracking method for pedestrians, through locating them and maintaining their identities to make their individual trajectories. In most existing data association-based tracking approaches, the motion information in the affinity model is always linear, but the motion of target is non-linear in real-world surveillance video, especially when there is occlusion. This paper proposes...

Xiaoyan Qiu, Yongqiang Zhang, Haitao Wu, Rui Yang, more

Polymer International > 68 > 2 > 218 - 224

The crystallization of capped ultrathin polymer films is closely dependent on film thickness and interfacial interaction. Using dynamic Monte Carlo simulations, the crystallization behaviors of polymer films confined between two substrates were investigated. The crystallization rate of confined polymers is reduced with high interfacial interactions. Above a critical strength of interfacial interaction,...

Zhiping Zhou, Chunye Li, Xiaoxiao Zhao, Fangzheng Zhou

Multimedia Tools and Applications > 2019 > 78 > 12 > 16329- 16343

Scene classification methods based on effective feature extraction and coding have obtained promising results in recent years. But the K-nearest neighbor search strategy in Locality-constrained Linear Coding (LLC) increases the complexity of the algorithm due to the exhaustive search. To solve the problem, an improved approximate nearest neighbor search strategy is proposed to improve the computational...

Journal of Separation Science > 41 > 23 > 4394 - 4401

Sulfadiazine is an environmental pollutant derived from abuse of antibiotics. Its content in environmental water is closely related to human health. Thus, a novel dual‐emission surface molecularly imprinted nanosensor is designed for the specific adsorption and detection of sulfadiazine. In the system, blue emissive carbon quantum dots wrapped with silica served as the internal reference signal for...
