Exponential Synchronization of Uncertain Complex Dynamical Networks with Delay Coupling

This paper studies the global exponential synchronization of uncertain complex delayed dynamical networks. The network model considered is general dynamical delay networks with unknown network structure and unknown coupling functions but bounded. Novel delay-dependent linear controllers are designed via the Lyapunov stability theory. Especially, it is shown that the controlled networks are globally exponentially synchronized with a given convergence rate. An example of typical dynamical network of this class, having the Lorenz system at each node, has been used to demonstrate and verify the novel design proposed. And, the numerical simulation results show the effectiveness of proposed synchronization approaches.

Impulsive synchronization of two coupled complex networks with time-delayed dynamical nodes

In this paper, we investigate the impulsive synchronization between two coupled complex networks with time- delayed dynamical nodes. Based on the Lyapunov stability, the linear feedback control and the impulsive control theories, the linear feedback and the impulsive controllers are designed separately. By using the generalized Barbalat＇s lemma, the global asymptotic impulsive synchronization of the drive-response complex networks is derived and some corresponding sufficient conditions are also obtained. Numerical examples are presented to verify the effectiveness and the correctness of the synchronization criteria.

High resolution crop intensity mapping using harmonized Landsat-8 and Sentinel-2 data

An increase in crop intensity could improve crop yield but may also lead to a series of environmental problems, such as depletion of ground water and increased soil salinity. The generation of high resolution(30 m) crop intensity maps is an important method used to monitor these changes, but this is challenging because the temporal resolution of the 30-m image time series is low due to the long satellite revisit period and high cloud coverage. The recently launched Sentinel-2 satellite could provide optical images at 10–60 m resolution and thus improve the temporal resolution of the 30-m image time series. This study used harmonized Landsat Sentinel-2(HLS) data to identify crop intensity. The sixth polynomial function was used to fit the normalized difference vegetation index(NDVI) and enhanced vegetation index(EVI) curves. Then, 15-day NDVI and EVI time series were then generated from the fitted curves and used to generate the extent of croplands. Lastly, the first derivative of the fitted VI curves were used to calculate the VI peaks;spurious peaks were removed using artificially defined thresholds and crop intensity was generated by counting the number of remaining VI peaks. The proposed methods were tested in four study regions, with results showing that 15-day time series generated from the fitted curves could accurately identify cropland extent. Overall accuracy of cropland identification was higher than 95%. In addition, both the harmonized NDVI and EVI time series identified crop intensity accurately as the overall accuracies, producer’s accuracies and user’s accuracies of non-cropland, single crop cycle and double crop cycle were higher than 85%. NDVI outperformed EVI as identifying double crop cycle fields more accurately.

New Fixed Point Results of Generalized g-Quasi-Contractions in Cone b-Metric Spaces Over Banach Algebras

In this paper, we introduce the concept of generalized g-quasi-contractions in the setting of cone b-metric spaces over Banach algebras. By omitting the assump- tion of normality we establish common fixed point theorems for the generalized g- quasi-contractions with the spectral radius r（λ） of the g-quasi-contractive constant vector λ satisfying r（λ） ∈[0,1） in the setting of cone b-metric spaces over Banach al- gebras, where the coefficient s satisfies s ≥ 1. The main results generalize, extend and unify several well-known comparable results in the literature.

A Comparative Study of English Transitional Light Verb Morpheme“-ize”and Chinese“化”

English transitional light verb morpheme"-ize"and Chinese"化"have been discussed in English and Chinese languages from different research perspectives.Based on English-Chinese Equivalence Translation,Contrastive Analysis and CodeSwitching in Inter-Cultural Communication,the paper mainly discusses their differences in equivalence translation,word class and pragmatic translation.The nouns,adjectives and verbs investigated respectively are realized by adding morpheme"化",which are equal to English transitional light verb"-ize"and its derivations information.However,from the contrastive analysis expression,there is word class difference between morpheme"-ize"and Chinese"化"in semantic view.In Chinese language,"X+化"is regarded as noun while"X+ize"verb in English.On the top of that,influenced by code-switching strategies,the two morphemes have distinctions in pragmatic translation according to grammatical rules and cultural diversities between Chinese and English.

Vaginal hysterectomy or laparoscopic assisted vaginal hysterectomy for enlarged myomatous uterus:a randomized clinical trial

Objective:To compare the intraoperative condition and short-term outcomes of vaginal hysterectomy(VH) and laparoscopic assisted vaginal hysterectomy(LAVH) for enlarged myomatous uterus. Methods:Fifty patients from Peking Union Medical College Hospital(PUMCH) were randomly assigned to two treatment groups:VH(n= 23) and LAVH(n= 27).All procedures were performed by a single senior surgeon to maintain homogeneity. Results:The baseline characteristics of the two groups were comparable.The operative time for LAVH was significantly longer than for VH(76.7±23.2 vs.57.6±23.5 min,P<0.05),and LAVH costs more money than VH(6,923.07±622.96 vs.5,974.46±1,408.08 RMB,P<0.05).Major complications,uterine weight and the length of hospital stay were comparable between VH and LAVH group.One case of VH was converted to LAVH due to adhesion. Conclusions:Compared with LAVH,VH is a time- and cost-saving operative technique for enlarged myomatous uterus.VH should be the primary method for uterine removal,but LAVH may have advantages when adhesion is present.

Effect of ultrasound-guided acupotomy vs electro-acupuncture on knee osteoarthritis:a randomized controlled study

OBJECTIVE:To investigate the effect of acupotomy on knee osteoarthritis(KOA),compared to electro-acupuncture(EA).METHODS:Sixty KOA patients were randomly divided into 2 groups:ultrasound-guided acupotomy group and EA group;each had 3 weeks' therapy.After the treatment,by contrast before and after therapy,by comparing curative effects among groups,we looked into disease improvement degree through activities of daily living score(ADL),hospital for special surgery index(HSS),visual analogue scales score(VAS) and knee joint's infrared thermal imaging detection.RESULTS:Graded by ADL,the excellent rate in acupotomy group was much higher than EA group;both acupotomy group and EA group had obviouschanges in HSS index before and after the therapy(P < 0.01).And there was remarkable difference in HSS index variation between the groups(P < 0.01).Acupotomy group and EA group showed big difference in pain index before and after treatment(P <0.01).Apparent difference also existed in the comparison among groups(P < 0.01).Both acupotomy group and EA group had apparent changes in infrared thermal imaging detection before and after the treatment(P < 0.01).CONCLUSION:Acupotomy and EA both have significant effects in KOA treatment;the former is better than the latter in relieving pain and improving knee functions.

Meta-analysis on randomized controlled trials for scalp acupuncture treatment of stroke：A systematic review

OBJECTIVE:To conduct a systematic review to assess the clinical effectiveness of scalp acupuncture(SA) for stroke.METHODS:Literature searches were performed in7 databases up to 16 August 2014,and all the randomized controlled trials(RCTs) in which SA therapy was administered to stroke patients were selected.Methodological quality was assessed using the Jadad score,the Cochrane risk of bias assessment,and the Standards for Reporting Interventions in Clinical Trials of Acupuncture.RESULTS:Of a total of 2086 papers,21 RCTs were selected.Meta-analysis revealed significant differences in the total efficacy rates of the SA group and the body acupuncture(BA) group vs the medication group(P < 0.002,P < 0.000 001,respectively),the SA plus BA group vs the BA group(P < 0.001);in the motor function of the SA plus BA group vs the BA group(P = 0.077);and in the nerve function of the SA group vs the SA plus BA group(P < 0.0001).CONCLUSION:The results of our systematic review showed that SA therapy may exhibit effects in treatment efficacy and in the recovery of motor and nervous functions in patients with acute to chronic stroke.However,because of the lack of methodological quality,the thoroughly planned clinical studies are still required.

Effects of Feiwei granules in the treatment of idiopathic pulmonary fibrosis:a randomized and placebo-controlled trial

OBJECTIVE： To document the therapeutic effects of Feiwei granules （FGs） for idiopathic pulmonary fi-brosis （IPF）.METHODS： One hundred cases with IPF were ran- domized into the treatment group （80） and control group （20）. Both groups were given basic treat- ment with prednisone. The treatment group was given FGs, and the control group was given Jinshui- bao capsules （JCs）. Treatment lasted for 6 months. The Medical Research Council Dyspnea Scale （MRCDS）, the Saint George＇s Hospital Respiratory Questionnaire （SGHRQ）, pulmonary function, the Traditional Chinese Medicine Syndrome Score （TC- MSS）, 6-min walking test （6MWT） and blood gas analyses were recorded before the study as well as 3 months and 6 months after treatment.RESULTS： FGs showed greater efficacy than the control in certain parameters between before the study and 6 months, and between 3 months and 6 months, in the MRCDS, some indicators in the SGHRQ, and the TCMSS. There were no significant differences between the treatment group and con- trol group in the remainder of the indices evaluat- ed. In the treatment group, there were significant differences in before and after treatment in the MRCDS, SGHRQ, TCMSS and 6MWT.

Guasha improves the rating of perceived exertion scale score and reduces heart rate variability in male weightlifters:a randomized controlled trial

OBJECTIVE: To evaluate the effects of Guasha therapy on the rating of perceived exertion(RPE) scale score, and heart rate variability(HRV).METHODS: A randomized controlled trial of Guasha(skin scraping) was compared with a sham scraping group and control group. Sixteen sessions within an 8-week period were completed. Sixty-five male weightlifters who had undergone normal weightlifting training for a mean of 5 years before study commencement were recruited. The RPEscale score of "snatch", "clean and jerk" maneuvers(85% of one-repetition maximum), and HRV were measured before and after the intervention.RESULTS: The RPE scale score for snatch, clean and jerk were reduced significantly after intervention in the Guasha group and sham group. However, there was a significant difference in the low frequency(LF) domain and LF/high frequency(HF) ratio(P <0.05): the LF domain decreased, and the LF/HF ratio decreased.CONCLUSION: Guasha could be used to reduce the RPE scale score, and increase the response to HRV.Guasha could be considered as an alternative to some types of recovery from sports training.
