	Abstract:In this paper, the outage behavior of a decode-and-forward (DF) relaying network is studied in a two-hop diffusion-based molecular communication (MC) system. The MC system can be characterized by outage probability and outage events. Based on this event and probability, the robustness of the transmissions to fading is measured. Specifically, according to Shannon\'s capacity theorem and Fick\'s law, the outage probability of fading channels is investigated. The distribution characteristics of the channel gain is considered based on the proposed relaying system. The analysis of this article can be useful for the performance optimization of MC system.

	Abstract:As a new advancement of the theory of fractional dimensionality of electron states architecture in semiconductor heterostructure physics, more accurate estimation of the linewidth of energy level dispersion in GaAs based semiconductor heterostructures at a temperature of 300K has been made by adopting a modified energy level dispersion function featuring an asymmetric lineshape and the relevant dimensional similarity functions modified mainly by introducing a novel concept of quantization baseline of density of states. It is determined as about 0.00221eV, which is in the same order of magnitude with the previous result, but about 10% larger than that. This work may magnify the impact of the fractional dimensionality theory on the development of semiconductor quantum electronics and optoelectronics and even that of fundamental physics.

	Abstract:With the rapid development of the information technology, digital music is becoming an essential carrier of music communication. Researches of speech enhancement are penetrating deeply and have got a good performance recently, while it is relatively less in music denoising. In the applications of music information retrieval(MIR), such as automatic music transcription and music alignment, various noises may influence the performance of retrieval algorithms. In this paper, end-to-end approaches based on high-resolution representations are presented without manual feature extraction. The U-Net model cascades neural networks with different resolutions while the HRNet model fuses high-to-low resolutions to extract high-resolution features. To solve the lack of specialized music denoising database, we mix the music database MusicNet and the noise database NoiseX-92 with five different signal-to-noise ratios. Through the analysis of source to distortion ratio, the HRNet model outperforms the U-Net model. The results reveal that the resolution fusion methods of HRNet is more suitable for high-resolution feature extraction to reduce noises.

	Abstract:The traditional 12-lead electrocardiography (ECG) monitor system can record limited body surface potential (BSP) information at some particular area, where the cardiac state can only be roughly evaluated. In order to collect more heart information, in this study, a 32-lead BSP acquisition system is designed. The Wilson central terminal (WCT) is set as the reference electrode to obtain the BSPs at different points. To verify the proposed system, three sets of BSPs about healthy adult male are collected. By comparing the QRS complex of single cardiac cycle, an equilibrium point of BSP signal is defined (i.e. the amplitudes of R and S waves are clearly flipped) through this new system. Such equilibrium point can be a potential position index in clinical diagnosis.

	Abstract:In this paper, an original three-dimensional (3-D) indoor positioning system based on visible light communication (VLC) applying artificial bee colony (ABC) algorithm is proposed. ABC algorithm is an intelligent optimization algorithm that simulates swarm behavior, which has the advantages of pure principle, fewer control parameters, easy implementation, and strong global optimization ability. In the field of visible light positioning, some positioning systems that realize visible light positioning are based on a two-dimensional (2-D) plane, which is not applicable to actual scenarios. However, the ABC algorithm used in visible light positioning system can easily achieve real three-dimensional positioning with accuracy up to the millimeter level. Simulation results show that the average positioning error can reach about 2.6mm after 40 iterations at 1m height and the simulation considers the edge points. The result of track tracking simulation shows that the average error is 1.7mm and 90.4% of the sampling points have a positioning accuracy below 3.811mm. In addition, the convergence performance simulation shows that the average error can reach 3.8mm within 40 iterations under the SNR of 30dB, and the final average error is stable at 2.6mm. From the results, it turns out that the ABC algorithm is a promising method for indoor visible light localization.

	Abstract: An integral method for studying the health states is presented based on the random matrix theory and the classification theory of health states. The pulse of volunteer is labeled by the state 1,2,3,4 respectively, then the single-ring theorem is used to analyze the spectral distribution and mean spectral radius of the pulse, and the health state is obtained. The pulse data of 23 voluntary college students were processed, it has been found that the mean spectral radius of pulse approaches the smallest when the states are both disordered in physical and unbalanced in mental states which is named the state 3.

	Abstract:In the UAV network, high-speed movement of nodes will cause frequent network topology updates, making network management more complex and increasing network maintenance overhead. Clustering can increase network capacity, achieve reuse of space resources, and reduce energy consumption overhead. The existing clustering algorithms are proposed for fixed wireless sensor network, mobile ad hoc network with limited mobility or special application such as vehicle network. It is necessary to continue doing the research that could cope with the rapid changes of the network extension caused by the high-speed movement for the UAV.This paper proposes a modified sub-cluster head stable clustering algorithm (SHSC) for highly dynamic unmanned aerial vehicles, which introduces an improved maximum speed similarity parameter when electing a cluster head, so that nodes with similar motion trends are formed the same cluster. The sub-cluster head node is added in each cluster, and becomes a new cluster head immediately when the original cluster head fails or the energy is too low. It is benefit for enhancing the stability of the network. By simulating verification, SHSC is 27% higher than weighted clustering algorithm (WCA) in terms of energy consumption, 22% higher than improved weighted clustering algorithm (IWCA), and 5% higher than optimized stable clustering algorithm (OSCA). In terms of network stability, it is 26% higher than WCA, 22% higher than IWCA, and 19% higher than OSCA.

	Abstract:Due to too much data, the efficiency of l1 norm-Singular Value Decomposition (l1-SVD) algorithm becomes poor, this paper proposes a Preprocessing l1-SVD algorithm. This method is based on the frequency diversity array of L-type array. Firstly, the search space of the target position is preprocessed to reduce the search space by the inner product of the received data and the perception matrix. Then, l1-SVD algorithm is used to estimate the search space after proposed preprocessing. The simulation results show that the algorithm has better efficiency in the face of large amount of data, and the estimation accuracy is also improved compared with that without processing.
