Abstract

This paper examines the direction of arrival (DOA) estimation for polarized signals impinging on a sparse vector sensor array which is based on the maximum interelement spacing constraint (MISC). The vector array effectively utilizes the polarization domain information of incident signals, and the quaternion model is adopted for signals polarization characteristic maintenance and computational burden reduction. The features of MISC arrays are crucial to the mutual coupling effects reduction and higher degrees of freedom (DOFs). The quaternion data model based on vector MISC arrays is established, which extends the scalar MISC array into the vector MISC array. Based on the model, a quaternion multiple signal classification (MUSIC) algorithm based on vector MISC arrays is proposed for DOA estimation. The algorithm combines the advantages of the quaternion model and the vector MISC array to enhance the DOA estimation performance. Analytical simulations are performed to certify the capability of the algorithm.

Abstract

Partner selection is an important aspect of the customer collaborative product innovation process and aims to select innovative customer partners from huge numbers of customers, fast and accurately. The purpose of this article is to present a quantitative partner selection method based on the complex network theory. In this method, the complex network model of the Online Community Customer Network (OCCN) is constructed, and network centrality is used as the initial index of customer partner selection. Then, network efficiency and delta centrality are used to evaluate the effect of the index. An example is presented to reflect the feasibility and efficiency of the proposed method. Results validate the small-world and scale-free properties of the OCCN and show that betweenness centrality is the most appropriate index for partner selection in the OCCN.

235. Boosting self-trapped exciton emission from Cs3Cu2I5 nanocrystals by doping-enhanced exciton-phonon coupling.

Abstract

Self-trapped excitons (STEs) emission from halide perovskites with strong exciton-phonon coupling has attracted considerable attention due to the widespread application in optoelectronic devices. Nevertheless, the in-depth understanding of the relationship between exciton-phonon coupling and luminescence intensity remains incomplete. Herein, a doping-enhanced exciton-phonon coupling effect is observed in Cs3Cu2I5 nanocrystals (NCs), which leads to a remarkable increasement of their STEs emission efficiency. Mechanism study shows that the hetero-valent substitution of Cu+ with alkaline-earth metal ions (AE2+) causes a greater degree of Jahn–Teller distortion between the ground state and excited state structures of [Cu2I5]3− clusters as evidenced by our spectral analysis and first-principles calculations. As a consequence, an X-ray detector based on these Cs3Cu2I5:AE NCs delivers an X-ray imaging resolution of up to 10 lp·mm−1 and a low detection limit of 0.37 µGyair·s−1, disclosing the potential of doping-enhanced exciton-phonon coupling effect in improving STEs-emission and practical application for X-ray imaging.

Abstract

Hexagonal-phase NaYF4 (β-NaYF4) has been acknowledged to be one of the most efficient doping hosts to prepare bright lanthanide-doped luminescent nano-bioprobes for various biomedical applications. However, to date, it remains a great challenge to synthesize ultra-bright lanthanide-doped β-NaYF4 nano-bioprobes under a low reaction temperature by using conventional synthetic methods. Herein, we first develop an acetic acid (HAc)-mediated coprecipitation method for the preparation of ultra-bright lanthanide-doped β-NaYF4 nanoprobes under a low reaction temperature at 200 °C. Based on a series of comparative spectroscopic investigations, we show that the use of HAc in the reaction environment can not only promote the rapid α–β phase transformation of NaYF4 host at 200 °C within 1 h but also boost the absolute photoluminescence quantum yield (PLQY) of NaYF4 nanocrystals to 30.68% for near-infrared emission and to 3.79% for upconversion luminescence, both of which are amongst the highest values for diverse lanthanide-doped luminescent nanocrystals ever reported. By virtue of their superior near-infrared luminescence, we achieve optical-guided dynamic vasculature imaging in vivo of the whole body at a high spatial resolution (23.8 µm) under 980 nm excitation, indicating its potential for the diagnosis and treatment evaluation of vasculature-related diseases.

Abstract

A major epidemic is an evolutionary process of a complex system, which involves multiple parties, such as different groups and prevention and control departments. Thus, it is of practical importance to establish a multi-party game evolution model and study internal laws for curbing an epidemic. This study proposes a method of the combination of the infectious disease warehouse model and evolutionary game. We aim to explore the effects of the prevention and control policies and to have an insight into the influence of social public strategy choices with two-state (susceptible and infected state based on the warehouse model) people. Thus, we construct a tripartite evolutionary game model for two principal groups and the governmental prevention and control department during an epidemic, calculate the replicator dynamics equation and its evolutionary stability value, and conduct a sensitivity analysis of the key parameters. The results show that the governmental prevention and control department's strategy evolves the fastest. The infected (I) group relates to the loss apportionment ratios α (under efficient prevention and control strategy) and β (under inefficient prevention and control strategy), and the susceptible (S) group is easily influenced by opportunity cost e (average opportunity cost of individuals in Group S with crisis awareness).

Abstract

In sports data analysis and visualization, understanding collective tactical behavior has become an integral part. Interactive and automatic data analysis is instrumental in making use of growing amounts of compound information. In professional team sports, gathering and analyzing sportsperson monitoring data are common practice, intending to evaluate fatigue and succeeding adaptation responses, analyze performance potential, and reduce injury and illness risk. Data visualization technology born in the era of big data analytics provides a good foundation for further developing fitness tools based on artificial intelligence (AI). Hence, this study proposed a video-based effective visualization framework (VEVF) based on artificial intelligence and big data analytics. This study uses the machine learning method to categorize the sports video by extracting both the videos' temporal and spatial features. Our system is based on convolutional neural networks united with temporal pooling layers. The experimental outcomes demonstrate that the recommended VEVF model enhances the accuracy ratio of 98.7%, recall ratio of 94.5%, F1-score ratio of 97.9%, the precision ratio of 96.7%, the error rate of 29.1%, the performance ratio of 95.2%, an efficiency ratio of 96.1% compared to other existing models.

Abstract

Due to the currently insufficient consideration of task fitness and task coordination for task allocation in collaborative customized product development, this research was conducted based on the analysis of collaborative customized product development process and task allocation strategy. The definitions and calculation formulas of task fitness and task coordination efficiency were derived, and a multiobjective optimization model of product customization task allocation was constructed. A solution based on adaptive genetic algorithm was proposed, and the feasibility and effectiveness of the task allocation algorithm were tested and verified using a 5-MW wind turbine product development project as example.
