One is that the bound on the uncertainty existing in the controller is known, the other is that the bound is unknown. In the latter case, the simple adaptation laws for upper bound on the norm of the uncertainty is proposed. Using this adaptive upper bound, a variable structure control is designed. The proposed method does not guarantee the convergence of the adaptive upper bound to the real one but makes the system asymptotically stable.展开更多

Methods: The search strategy, inclusion and exclusion criteria were made according to the principle of evidence-based medicine. We performed a systematic search on China National Knowledge Infrastructure(CNKI), Wanfang Academic Journal Full-text Database(Wanfang), Chongqing VIP Database(CQVIP), Chinese Biomedical Literature Database(CBM), Pub Med, Excerpta Medica Database(EMBASE), Web of Science, Cochrane Library, and Cochrane Central Register of Controlled Trials(CENTRAL) for randomized controlled trials(RCTs) of acupuncture for allergic rhinitis between January 1990 and December 2015. The quality was evaluated by Cochrane Handbook for Systematic Reviews of Interventions Version 5.1, and the meta-analysis was conducted by Rev Man 5.3 version. Results: Twenty eligible RCTs were included into the meta-analysis after selection. Compared with antihistamines, the meta-analysis showed RR=1.241, 95%CI[1.15, 1.33], P〈0.00001, indicating that acupuncture achieved a better total effective rate for AR than antihistamines; MD=–0.93〈0, 95%CI[–1.22, –0.63], P〈0.00001, indicating that acupuncture is better than antihistamines in decreasing the total nasal symptom score(TNSS) in AR patients; and MD=1.46〉0, 95%CI[–10.84, 13.75], P=0.82, indicating that there was no statistical difference between acupuncture and antihistamines in regulating immunoglobulin E(Ig E) in AR patients. Compared with Bi Yan Kang Tablet, the meta-analysis has shown RR=1.50〉1, 95%CI[1.30, 1.73], P〈0.00001, indicating that acupuncture achieved a better total effective rate for AR than Chinese patent medicine Bi Yan Kang Tablet. Conclusion: Acupuncture alone can achieve a better total effective rate for AR than antihistamines and Bi Yan Kang Tablet. It is also better than antihistamines in improving clinical symptom scores; however, whether acupuncture is better than Bi Yan Kang Tablet needs further proof. As far as current data are concerned, there was no statistical difference between acupuncture and antihistamines in improving serum Ig E; further study is needed in this regard. The risk of bias due to absent randomization methods or blinding implementation decreased the evidence level of the overall conclusion.展开更多

Let {Xt} be a linear process defined by Xt =∑k=0^∞ψ kεt-k, where {ψk, k ≥ 0} is a sequence of real numbers and {εk, k = 0, ±1, ±2,...} is a sequence of random variables. Two results are proved in this paper. In the first result, assuming that {εk, k ≥ 1} is a sequence of asymptotically linear negative quadrant dependent (ALNQD) random variables, the authors find the limiting distributions of the least squares estimator and the associated regression t statistic. It is interesting that the limiting distributions are similar to the one found in earlier work under the assumption of i.i.d, innovations. In the second result the authors prove that the least squares estimator is not a strong consistency estimator of the autoregressive parameter a when {εk, k ≥ 1} is a sequence of negatively associated (NA) random variables, and ψ0 = 1, ψk = 0, k ≥ 1.展开更多
文摘The synchronization problem under two cases is considered. One is that the bound on the uncertainty existing in the controller is known, the other is that the bound is unknown. In the latter case, the simple adaptation laws for upper bound on the norm of the uncertainty is proposed. Using this adaptive upper bound, a variable structure control is designed. The proposed method does not guarantee the convergence of the adaptive upper bound to the real one but makes the system asymptotically stable.
