  • 简介:为多信道的脑电图(EEG)的独立来源分离(ISS)的一个神经网络方法在这份报纸被建议。用小浪的降噪的功能多尺度的分解,高周波的噪音从原版被移开(未加工)EEG。当加权的混合物和重量向量的表示被寻求第四顺序的cumulants的本地极值获得,然后,多信道的EEG被对待(即峭度系数)混合物。在这些进程步以后,加权的混合物被用作神经网络的输入,因此EEG的独立来源能一个一个地被分开。试验性的结果证明我们的方法为多信道的EEG的ISS是有效的。

  • 简介:因为它的吸引人的表演,超导的nanowire单身者光子察觉者(SNSPD)在极端紫、可见、在红外线附近的波长引起许多注意,并且它能在量信息技术是普遍的。然而,怎么增加罐头戏剧性地增加SNSPD的量效率的吸收仍然是一个顶研究问题。在这研究,洞综合的SNSPD的光吸收比上的事件媒介和洞材料的效果系统地用有限元素的方法被调查。模拟结果为光子表明那极化的平行到nanowire取向尽管nanowire的最大的吸收比对洞材料感觉迟钝,事件媒介的折射索引什么时候减少,确实增加。为垂直地极化的光子,事件媒介和洞材料起重要作用,并且吸收比曲线作为洞材料增加的折射索引接近平行案例。把结果基于这些,有能为平行、垂直的光子提高吸收比的前面照明结构的二洞综合的SNSPD被建议。最后,与高吸收比认识到极化无关的SNSPD的一个图案被介绍。

  • 简介:我们决定了在prostatic演算和更低的尿道之间的关联症状(LUTS),以及prostatic演算的预先安排的因素。为LUTS在我们的诊所介绍了的1527个病人,802经历了完全的评估,包括transrectalultrasonography,voidedbladder-3标本和国际prostatic症状分数(IPSS)。有prostatic演算的335个病人和没有prostatic演算的467个病人的一个总数分别地被划分成演算和没有演算组。严重LUTS和prostatic演算的预兆的因素用uni/multivariate分析被决定。全面IPSS分数是15.7卤9.2在演算和没有演算组织的9.2和14.1卤,分别地(P=0.013)。最大的流动率是12.1卤6.9和14.2卤8.2mLs?1在演算和没有演算组织,分别地(P=0.003)。在为预言严重LUTS的因素的univariate分析上,在年龄的差别(P=0.042),prostatic演算(P=0.048)并且前列腺炎(P=0.018)是统计上重要的。在multivariate分析上,然而,没有因素是重要的。在为预先安排的multivariate分析上prostatic演算的因素,在年龄的差别(P<0.001)并且前列腺体积(P=0.001)是重要的。到我们的知识,有prostatic演算的病人抱怨更严重的LUTS。然而,prostatic演算不是严重LUTS的一个独立预兆的因素。因此,不仅因为prostatic演算而且因为年龄和另外的因素,有prostatic演算的人有更严重的LUTS。另外,老年和大前列腺体积是为prostatic演算的独立人士预先安排因素。

  • 简介:AbstractBackgrounds:Physical activity (PA) and sedentary behavior (SB) have been associated with mortality, while the joint association with mortality is rarely reported among Chinese population. We aimed to examine the independent and joint association of PA and SB with all-cause mortality in southern China.Methods:A cohort of 12,608 China Hypertension Survey participants aged ≥35 years were enrolled in 2013 to 2014, with a followup period of 5.4 years. Baseline self-reported PA and SB were collected via the questionnaire. Kaplan-Meier curves (log-rank test) and Cox proportional hazards regression were performed to evaluate the associations of PA and SB on all-cause mortality.Results:A total of 11,744 eligible participants were included in the analysis. Over an average of 5.4 years of follow-up, 796 deaths occurred. The risk of all-cause mortality was lower among participants with high PA than those with low to moderate level (5.2% vs. 8.9%; hazards ratio [HR]: 0.75, 95% confidence interval [CI]: 0.61-0.87). Participants with SB ≥ 6 h had a higher risk of all-cause mortality than those with SB <6 h (7.8% vs. 6.0%; HR: 1.37, 95% CI: 1.17-1.61). Participants with prolonged SB (≥6 h) and inadequate PA (low to moderate) had a higher risk of all-cause mortality compared to those with SB < 6 h and high PA (11.2% vs. 4.9%; HR: 1.67, 95% CI: 1.35-2.06). Even in the participants with high PA, prolonged SB (≥6 h) was still associated with the higher risk of all-cause mortality compared with SB < 6 h (7.0% vs. 4.9%; HR: 1.33, 95% CI: 1.12-1.56).Conclusions:Among Chinese population, PA and SB have a joint association with the risk of all-cause mortality. Participants with inadequate PA and prolonged SB had the highest risk of all-cause mortality compared with others.
