The Extended Hybrid Carrier-Based Multiple Access Technology for High Mobility Scenarios

The hybrid carrier(HC)system rooted in the carrier fusion concept is gradually garnering attention.In this paper,we study the extended hybrid carrier(EHC)multiple access scheme to ensure reliable wireless communication.By employing the EHC modulation,a power layered multiplexing framework is realized,which exhibits enhanced interference suppression capability owing to the more uniform energy distribution design.The implementation method and advantage mechanism are explicated respectively for the uplink and downlink,and the performance analysis under varying channel conditions is provided.In addition,considering the connectivity demand,we explore the non-orthogonal multiple access(NOMA)method of the EHC system and develop the EHC sparse code multiple access scheme.The proposed scheme melds the energy spread superiority of EHC with the access capacity of NOMA,facilitating superior support for massive connectivity in high mobility environments.Simulation results have verified the feasibility and advantages of the proposed scheme.Compared with existing HC multiple access schemes,the proposed scheme exhibits robust bit error rate performance and can better guarantee multiple access performance in complex scenarios of nextgeneration communications.

Hyperchaos evolved from the Liu chaotic system

This paper introduces a new hyperchaotic system by adding an additional state into the third-order Liu chaotic system. Some of its basic dynamical properties, such as the hyperchaotic attractor, Lyapunov exponent, fractal dimension and the hyperchaotic attractor evolving into chaotic, periodic, quasi-periodic dynamical behaviours by varying parameter d are studied briefly. Various attractors are illustrated not only by computer simulation but also by conducting an electronic circuit experiment.

Shear wave splitting analysis of local earthquakes from dense arrays in Shimian,Sichuan

The Shimian area of Sichuan sits at the junction of the Bayan Har block.Sichuan-Yunnan rhombic block,and Yangtze block,where several faults intersect.This region features intense tectonic activity and frequent earthquakes.In this study,we used local seismic waveform data recorded using dense arrays deployed in the Shimian area to obtain the shear wave splitting parameters at 55 seismic stations and thereby determine the crustal anisotropic characteristics of the region.We then analyzed the crustal stress pattern and tectonic setting and explored their relationship in the study area.Although some stations returned a polarization direction of NNW-SSE.a dominant polarization direction of NW-SE was obtained for the fast shear wave at most seismic stations in the study area.The polarization directions of the fast shear wave were highly consistent throughout the study-area.This orientation was in accordance with the direction of the regional principal compressive stress and parallel to the trend of the Xianshuihe and Daliangshan faults.The distribution of crustal anisotropy in this area was affected by the regional tectonic stress field and the fault structures.The mean delay time between fast and slow shear waves was 3.83 ms/km.slightly greater than the values obtained in other regions of Sichuan.This indicates that the crustal media in our study area had a high anisotropic strength and also reveals the influence of tectonic complexity resulting from the intersection of multiple faults on the strength of seismic anisotropy.

Exploration on medication patterns of “External Treatment” in the ancient Chinese medical book Liu Juanzi Guiyi Fang

Background:To obtain the medication patterns of“External Treatment”by analyzing the prescriptions for the“External Treatment”in a Chinese ancient book called Liu Juanzi Guiyi Fang(Liu Juanzi’Ghost-Bequeathed Prescriptions,written by Liu Juanzi in 499 C.E.).Methods:The prescriptions for“External Treatment”and primary traditional Chinese medicines in Liu Juanzi’Ghost-Bequeathed Prescriptions were analyzed using data mining methods,such as frequency analysis and cluster analysis,after screening for prescriptions related to“External Treatment”in Liu Juanzi’Ghost-Bequeathed Prescriptions.The Database of Prescriptions for External Treatment in Liu Juanzi Guiyi Fang was then established.Results:The earliest Chinese characters for“Yin”and“Yang”were found on“oracle bones”.These bones were the skeletal remains of different animals,and were used in ancient Chinese divination practices going all the way back to the 14th century B.C.Simply put,“Yin”is the cold and“Yang”is the warm.In traditional Chinese medicine,this concept of dualism and its fundamental principle underlie physiology,pathology,and the treatment of illnesses.The“External Treatment”discussed in Liu Juanzi’Ghost-Bequeathed Prescriptions primarily adopts the methods of“Warming Yang”,“Cooling Heat(Yang)”,and“Qu Xie(dispelling pathogenic factors of epidemic diseases)”,as well as“Huo Xue(promoting blood circulation)and promoting tissue regeneration.In Chinese medicine,“Si Qi(cold as winter,cool as autumn,warm as spring,hot as summer)”,“Wu Wei(five flavors:sweet,pungent,salty,sour,and bitter)”used to describe the properties of herbs.In Liu Juanzi’Ghost-Bequeathed Prescriptions,most of the medicines used were more“Sweet”,“Pungent”,“Warm”,and the“Channel Tropism”were primarily distribute to the“Liver”,“Heart”,“Stomach”,and“Large intestine meridian”.Conclusion:The data mining method systematically summarized the medication characteristics of the prescriptions for“External Treatment”in Liu Juanzi’Ghost-Bequeathed Prescriptions.The characteristics of the“External Treatment”in this book include“supporting healthy Qi”and“promoting Qi and Blood circulation”which as the top priority,applying both“Attacking and Supplementing methods”as the focus,and combining“Supplementing methods”with“Elimination methods”.It has provided theoretical guidance in“External Treatment”for surgery of traditional Chinese medicine.
