According to the mechanism of EMG signal, we know that the sacrificial electrical signal is with weak signal, low frequency, alternating, nonlinear and non-stationary characteristics. Nonlinear analysis includes higher order spectral analysis and fractal and chaos analysis.Chaos theory is one of the main parts of nonlinear science, and the electrical signal of the surface has a strong randomness, so we could consider the nonlinear analysis of EMG signals from the perspective of chaos. We mainly studied on the nonlinear analysis algorithm of EMG signal detailedly in this paper. Experiments show that,according to the quantitative analysis of several important parameters of rolling massage with chaos theory, we can measure objectively the action situation of related muscle groups in the operation course, then guide the professional massage students to understand the norms of operation in training of operation and help to lead their manipulation to the best power structure.

Soil autotrophic bacterial communities play a significant role in the soil carbon (C) cycle in paddy fields, but little is known about how rhizosphere soil microorganisms respond to different long-term (35 years) fertilization practices under double rice cropping ecosystems in southern China. Here, we investigated the variation characteristics of rhizosphere soil RubisCO gene cbbL in the double rice ecosystems of in southern China where such fertilization practices are used. For this experiment we set up the following fertilizer regime: without any fertilizer input as a control (CK), inorganic fertilizer (MF), straw returning (RF), and organic and inorganic fertilizer (OM). We found that abundances of cbbL, 16S rRNA genes and RubisCO activity in rhizosphere soil with OM, RF and MF treatments were significantly higher than that of CK treatment. The abundances of cbbL and 16S rRNA genes in rhizosphere soil with OM treatment were 5.46 and 3.64 times higher than that of CK treatment, respectively. Rhizosphere soil RubisCO activity with OM and RF treatments increased by 50.56 and 45.22%, compared to CK treatment. Shannon and Chao1 indices for rhizosphere soil cbbL libraries with RF and OM treatments increased by 44.28, 28.56, 29.60, and 23.13% compared to CK treatment. Rhizosphere soil cbbL sequences with MF, RF and OM treatments mainly belonged to Variovorax paradoxus, uncultured proteobacterium, Ralstonia pickettii, Thermononospora curvata, and Azoarcus sp.KH33C. Meanwhile, cbbL-carrying bacterial composition was obviously influenced by soil bulk density, rhizosphere soil dissolved organic C, soil organic C, and microbial biomass C contents. Fertilizer practices were the principal factor influencing rhizosphere soil cbbL-carrying bacterial communities. These results showed that rhizosphere soil autotrophic bacterial communities were significantly changed under conditions of different long-term fertilization practices Therefore, increasing rhizosphere soil autotrophic bacteria community with crop residue and organic manure practices was found to be beneficial for management of double rice ecosystems in southern China.

Effect of the Oxygen Flux Ratio on the Structural and the Optical Properties of Silver-oxide Films Deposited by Using the Direct-current Reactive Magnetron Sputtering Method

Xiao-Yong Gao,Hong-Liang Feng,Zeng-Yuan Zhang,Jiao-Min Ma,Meng-Ke Zhao,Chao Chen,Jin-Hua Gu,Shi-E Yang,Yong-Sheng Chen,Jing-Xiao Lu 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.58 No.2

Using values of the oxygen flux ratio (OFR = [O2]/[Ar]) ranging from 0 to 0.5, authors deposited a series of silver-oxide (Ag_xO) films on glass substrates by direct-current reactive magnetron sputtering (DC sputtering) at a substrate temperature of 150 ℃. The effect of the OFR on the film’s structural and optical properties was systematically investigated by using X-ray diffractometry, scanning electron microscopy and spectrophotometry. The Ag_xO films deposited clearly show an evolution of the film’s phase structure from the biphased (Ag + Ag_2O) structure to the biphased (AgO + Ag_2O) structure and then to the single-phased (Ag_2O) structure as value of the OFR increases. Accordingly, the film’s surface morphology, related to the film’s crystalline structure, clearly changes from a loose and porous surface structure to a compact surface structure and then to a pyramid-like surface structure with increasing value of the OFR. The novel porous structure may be attributed to the interruption of the silver’s growth course by the AgO on the film’s surface. Notably, a single-phased Ag_2O film is deposited by DC-sputtering at OFR = 0.5 due to the dual effects of thermal decomposition of the AgO phase and a combination reaction of AgO and Ag to Ag_2O. The oscillations both in the film’s reflectivity and transmissivity spectra are strengthened with increasing OFR, indicating an evolution from the metallic behavior of the biphased (Ag + Ag_2O) film to the dielectric behavior of the biphased (Ag_2O + AgO) film and the single-phased Ag2O film. The fitted optical absorption edges of the Ag_2O and the Ag_xO films deposited at values of the OFR of 0.5 and 0.33 are approximately 2.43 eV and 2.34 eV, respectively. The absorption edges are closely related to the direct interband transitions.

Monitoring Analysis and Numerical Simulation of the Land Subsidence in Linear Engineering Areas

Chao Jia,Xiao Yang,Jing Wu,Pengpeng Ding,Chao Bian 대한토목학회 2021 KSCE JOURNAL OF CIVIL ENGINEERING Vol.25 No.7

Non-uniform land subsidence can cause subgrade deformation and threaten the safety of linear projects such as high-speed railways. The Lunan high-speed railway is taken as the research background. Combined with the hydrogeological and engineering geological conditions, the regional land subsidence is analyzed by the combined method of the differential interferometric synthetic aperture radar (D-InSAR) and small baseline subset interferometric synthetic aperture radar (SBAS-InSAR), which is verified by using precise leveling and GPS monitoring data. The accurate land subsidence analysis of large-scale linear engineering is realized. The distribution situation and change laws of land subsidence in linear engineering areas are revealed. Then, a three-dimensional coupled numerical model of land subsidence along a large-scale linear project is established by using the finite difference method. The spatial distribution characteristics of land subsidence in the linear engineering area are quantitatively analyzed and predicted. The main factors affecting land subsidence and the degree of land subsidence are discussed while keeping the pumping rate constant. The results show that: 1) The combined method of D-InSAR and SBAS-InSAR has high accuracy in the land subsidence monitoring of linear engineering. 2) There are five non-uniform settlement funnels along the Lunan high-speed railway. The groundwater over-extraction and coal mining are the main reasons for the land subsidence. 3) Realizing water source conversion and reduce groundwater exploitation are the main factors in linear engineering areas as soon as possible.

Structural and Optical Properties of RF Magnetron Reactively Sputtered Ag2O Film

Xiao-Yong Gao,Jiao-Min Ma,Chao Chen,Meng-Ke Zhao,Jin-Hua Gu,Jing-Xiao Lu 한국물리학회 2012 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.60 No.5

A series of <111> oriented Ag2O films was deposited onto glass substrates by using RF magnetron reactive sputtering at different flow ratios (FRs) of oxygen to argon. The Ag2O film deposited at FR = 0.667 was the best <111> oriented film due to dual contributions from both lattice strain and film stress. The films’ transmissivity of over 70% in the near-infrared region indicated that Ag2O films are not suitable for applications as transparent conductive films in the visible region. Ag2O films deposited at FRs from 0.467 to 0.800 had optical band gaps ranging from 3.266 eV to 3.107 eV. The redshift in the films’ absorption edge may be attributed to the decrease in the lattice strain with increasing in FR.

Xiao, Yang,Liu, Jun,Huang, Xin-En,Guo, Jian-Xiong,Fu, Peng-Chao,Huang, Xiao-Hong,Zhou, Juan,Ye, Ai-Qin Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.2

Objective: to investigate the effect and side effects of recombinant human interleukin - 11 (rhIL - 11, in Chinese Juheli, produced by Qi Lu Biotechnology CO., LTD) in the second prevention of chemotherapy induced thrombocytopenia (CIT). Methods: Cancer patients with CIT were recruited and were treated with rhIL - 11 (treatment phase, TP), and in the following cycle, all these patients administered with rhIL - 11 24 hours immediately after chemotherapy (preventive treatment phase, PTP). Duration and severity of thrombocytopenia between two phases were compared. Results: for patients in TP or PTP, nadir values of platelet were ($29.28{\pm}20.08){\times}10^9/L$ and ($45.24{\pm}19.66){\times}10^9/L$, duration of thrombocytopenia in TP and PTP was ($11.52{\pm}4.33$) and ($8.20{\pm}+2.77$)days, recovery time was ($19.40{\pm}3.89$)and ($13.44{\pm}3.02$)days, duration of rhIL - 11 administration was ($10.68{\pm}2.46$)and ($6.28{\pm}1.77$)days, number of patients needing platelet infusion was 16and4 respectively, all differences were statistically significant (p value were 0.007, 0.002, 0.000, 0.000, 0.034 respectively). For TP and PTP, number of patients with hemorrhage was 8 and 4, duration of bleeding was ($5.00{\pm}0.82$) and ($4.50{\pm}0.71$) days respectively, with no statistically significant difference. Adverse reactions mainly included fever, edema, arrhythmia, joint pain, fatigue, skin rash, headache, dizziness, etc., all were not statistically significant between TP and PTP. Conclusion: rhIL - 11 could be well tolerated and is effective that could reduce the duration, severity of CIT, platelet transfusion, and incidence of bleeding, as well as shorten the recovery time, duration of rhIL - 11 administration. Thus, rhIL - 11 could be commended in the second prevention of CIT for patients with cancer.
