Background Cardiorespiratory fitness reduction is potentially related to function/structure,and activity of the stroke patients may be associated with increased risk of cardiovascular disease. Whole body vibration（WBV）training is an efficient alternative therapy for neurological conditions. However,no study has investigated the effects of WBV training on cardiorespiratory fitness in patients with subacute stroke. This single-blinded randomized controlled trial was conducted to assess the effects WBV training on cardiorespiratory fitness and quality of life in individuals with subacute stroke. Methods Thirty-three people with subacute stroke（66.56±5.25 years）were enrolled from 87 patients initially screened（25 patients were excluded by inclusion/exclusion criteria,13 patients for other reasons,16 patients declined participation）. Participants were randomly assigned to the low-intensity WBV group（LWBV）,high-intensity WBV group（HWBV）and a control group（No WBV）.All participants of low-and high-intensity WBV group were exercised on a vibration platform,and the control group performed the same exercise without WBV. Outcome measurements included oxygen uptake（VO2）rate and walking distance during the 6-Minute Walk Test（6 MWT）,and quality of life（Short-Form 12 Health Survey,SF-12）. The measurements were performed by a researcher at baseline and immediately after the 8-week WBV intervention period. Results Statistical analysis revealed a significant time effect for VO2 rate and walking distance achieved during 6 MWT,and the SF-12 physical composite score domain in all three groups after the 8-week treatment period（P0.05）. Conclusions The addition of the 8-week WBV program to the leg exercise protocol is not more effective in enhancing cardiorespiratory fitness and quality of life than leg exercises alone in subacute stroke p

Background Whole-body vibration(WBV) therapy has become a common treatment in rehabilitation of various patient populations. While it has been shown in healthy young adults that the oxygen consumption rate(VO_2)and heat rate(HR) are significantly increased when WBV is added to exercise. However, the cardiovascular response to WBV in patients with subacute stroke is unknown. The objective of this study was to determine the acute cardiovascular responses to WBV during the various exercises in different WBV conditions in patients with subacute stroke(onset less than 3 months). Methods A total of 54 subjects with subacute stroke performed six exercises while being exposed to 3 WBV conditions:(1) no WBV,(2) low WBV intensity [amplitude: 0.6 mm,frequency: 20 Hz, peak acceleration: 0.96 gravitational constant(G)], and(3) high WBV intensity(amplitude:0.44 mm, frequency: 30 Hz, peak acceleration: 1.61 G). The cardiovascular responses(HR and VO_2) were measured by a FitMateTMPro metabolic system during the 6 exercises. Two-way repeated measures ANOVA was used to compare the VO_2, and HR data across the different conditions. In addition, we calculated the rate pressure product(RPP) =(HR × systolic blood pressure)/100, for measuring the myocardial oxygen demand. Two-way ANOVA with repeated measures was used to compare the RPP data across the different test conditions. Results Exposure to WBV(high-and low-intensity protocols) significantly induced higher VO_2 by 0.35-1.07 mL·kg-1·min-1(P0.05). For RPP, there was an overall significant effect between pre-and post-WBV(P<0.001). The main effect of WBV intensity(P=0.572), and intensity × time interaction effect(P=0.756), however,were not significant. Conclusions HR and VO_2 are increased significantly with ad

Real-time performance analysis of non-saturated and non-slotted Ethernet based on a two-dimensional collision state model

引用

Frontiers of Computer Science 2015年第5期9卷 788-805页

作者： Ronggang BAI Jiqiang xia Qingfeng man School of Information Science and Technology Beijing Forestry University Beijing 100083 China School of Mechanical Engineering and Automation Beihang University Beijing 100191 China

This paper proposes a new method to analyze Ethernet performance. Currently, most studies on Ethernet performance assume that the channel is divided into time slots, or the network load is saturated with little attention to a non-slotted channel and the non-saturation status. However, this situation is more consistent with the practical application of Ethernet. This paper first calculates the original collision probability and the retransmission collision probability in the original load, then obtains the retransmission load of the network based on those two collision probabilities, and finally acquires the actual load of the network by an iterative method. In addition, the accuracy of the analysis is checked against simulation results.

Quantum Stackelberg Duopoly Game in Depolarizing Channel

引用

Communications in Theoretical Physics 2008年第1期49卷 111-116页

作者： ZHU xia KUANG Le-man Department of Physics Hunan Normal University Changsha 410081 China

In this paper, we investigate the quantum Stackelberg duopoly （QSD） game in the noise environment with the depolarizing channel expressed by the Kraus-operator representation. It is found that the presence of the damping in the depolarizing channel always leads to the decrease of the quantities of the moves and payoffs of the two players in the QSD game. It is indicated that under certain conditions the first-mover advantage in the QSD game can be weakened due to the presence of the damping in the depolarizing channel.

Rapid diagnostic methods for classifying avian leukosis subgroups in the field were needed for routine, large-scale screening. As a first step in method development, we inserted the avian leukosis virus subgroup A （ALV-A） env gene into plasmid pcDNA3.1/Zeo （＋） and used this construct to transfect DF-1 cells. Zeocin-resistant cells were obtained after 2 weeks of zeocin selection. Then, the cells were analyzed using PCR, immunofluorescence, and Western blot for expression of the envA-encoded envelope protein after 30 serial passages. The DF-1/A cell line was completely resistant to 104 TCIDso/0.1 mL （50% tissue culture infective dose）ALV-A and was partially resistant to 10~ TCIDs0/0.1 mL ALV-A viral particles. By comparing the DF-1/A and DF-1 cell lines, an ALV-A isolate was identified using a gag-specific ELISAfor capsid protein p27. Thus, we established a DF-1/A cell line that was resistant to ALV-A infection. This cell line will be useful as a diagnostic tool.

基于人力资本理论研究脱贫户收入影响因素,对于巩固脱贫攻坚成果同乡村振兴有效衔接具有重要意义。应用实地调查法、OLS多元线性回归方法,从异质性角度分析影响脱贫户收入增长因素,通过对Y省3856户脱贫户的调查研究得到如下结论:教育和健康水平高可有效提升家庭收入,其中健康因素影响更大;劳动力迁移与脱贫户收入体现出极显著相关性,工资性收入是脱贫户收入的主要来源,并且迁移距离越远对家庭人均工资性收入的回报越高,但对家庭人均经营性收入损耗也越大;乡村振兴重点帮扶区县就业技术培训效果较非重点区县更好,但整体而言与家庭人均工资性收入和家庭人均经营性收入呈现反向变化的因果关系,原因在于培训内容与劳动力需求出现错配,就业技术培训并未取得预期效果,技能型人力资本提升是未来投资的重难点。此外,不同性别和民族的脱贫户并没有表现出明显的人力资本收入回报的差异。基于此提出要提升就业技术培训质量、强化健康帮扶、引导转移就业和分层分类帮扶等措施促进脱贫户可持续增收,助力巩固脱贫成果同乡村振兴有效衔接。

It was observed that the atomic fluorescence emission due to signal during the determination of As（Ⅲ） in the mixture of As（Ⅲ） and As（V） could has a 10% to 40% of fluorescence emission As（V）. Besides, interferes from heavy metals such as Pb（Ⅱ）, Cu（Ⅱ） can cause severe increase of the signals as compared to the insignificant effects caused by Cd（Ⅱ）, Zn（Ⅱ）, Mn（Ⅱ） and Fe（Ⅲ）. On the basis of further studies, the masking agent of 8-hydroxyquinoline was used as an efficient agent to eliminate interference of As（V） emission and the heavy metal of Cu^2＋ and Pb^2＋ in the measurements of arsenic species, After a series standard additions and CRM researches, a sensitive and interference-free analytical procedure was developed for the speciation of arsenic in samples of porewaters and sediments in Poyang Lake, China.

We study the differential equations w2＋ R（z）（w（k））2 = Q（z）, where R（z）, Q（z） are nonzero rationalfunctions. We prove （1） if the differential equation w2 ＋R（z）（w＇）2= Q（z）, where R（z）, Q（z） are nonzero rational functions, admits a transcendental meromorphic solution f, then Q= C （constant）, the multiplicities of the zeros of R（z） are no greater than 2 and f（z） = √C cos α（z）, where α（z） is a primitive of 1 such that √C cos α（z） is a transcendental meromorphic function. （2） if the differential equation w2 ＋ R（z）（w（k））2 = Q（z）, where k ≥ 2 is an integer and R, Q are nonzero rational functions, admits a transcendental meromorphic solution f, then k is an odd integer, Q ≡ C （constant）, It（z） ≡ A （constant） and f（z） = √C cos（az ＋ b）, where a2k = A1/A.

The oxidization of pure Li is rarely discussed,but substantially important in the design and optimization,especially the failure mechanism of Li metal anode for rechargeable *** this context,the Li metal and inherent LieLi_(2)O interface after oxidization are examined using first principles *** results demonstrated that in Li itself,the Li ion exhibits a fluid-like transport feature,especially in the vacancy-assisted *** fresh Li surface can be oxidized quickly in air with a thick cover(mainly Li oxides),and an inherent LieLi_(2)O interface is,therefore,*** the lowest surface energy,the Li(111)plane is revealed with a strong capability of adsorbing O and N atoms to form the distorted XLi6(X=O,N,etc.)octahedra in the outmost surface *** the Li ion migrates fast in Li itself,the LieLi_(2)O interface shows a sluggish Li diffusion kinetic in Li_(2)O *** ultimately leads to the Li diffusion prefers to go along the interface boundary in Li side,which loosens the LieLi2O interface structure to result in the exfoliation of surface metastable Li_(2)O spontaneously during electrochemical cycles in Limetal batteries.
