Polymeric microwave actuators combining tissue-like softness with programmablemicrowave-responsive deformation hold great promise for mobile intelligentdevices and bionic soft robots. However, their application is challenged by restricted electromagneticsensitivity and intricate sensing coupling. In this study, a sensitized polymericmicrowave actuator is fabricated by hybridizing a liquid crystal polymer with Ti3C2Tx(MXene). Compared to the initial counterpart, the hybrid polymer exhibits unique spacechargepolarization and interfacial polarization, resulting in significant improvements of230% in the dielectric loss factor and 830% in the apparent efficiency of electromagneticenergy harvest. The sensitized microwave actuation demonstrates as the shortenedresponse time of nearly 10 s, which is merely 13% of that for the initial shape memory polymer. Moreover, the ultra-low content of MXene (upto 0.15 wt%) benefits for maintaining the actuation potential of the hybrid polymer. An innovative self-powered sensing prototype that combinesdriving and piezoelectric polymers is developed, which generates real-time electric potential feedback (open-circuit potential of ~ 3 mV) duringactuation. The polarization-dominant energy conversion mechanism observed in the MXene-polymer hybrid structure furnishes a new approachfor developing efficient electromagnetic dissipative structures and shows potential for advancing polymeric electromagnetic intelligent devices.

BACKGROUND Alcohol consumption is a known modifiable risk factor for atrial *** association,however,might differ according to *** investigated gender-specific associations between alcohol consumption and incident atrial fibrillation in an elderly Chinese *** Our study participants were elderly residents(≥65 years)recruited from five community health centers in the urban area of Shanghai(n=6,618).Alcohol intake was classified as never drinkers and current light-to-moderate(<40 g/day)and heavy drinkers(≥40 g/day).Atrial fibrillation was detected by a 30-s single-lead electrocardiography(ECG,AliveCor®Heart Monitor)and further evaluated with a regular 12-lead *** During a median of 2.1 years(interquartile range:2.0−2.2)follow-up,the incidence rate of atrial fibrillation was 1.10%in all study *** was slightly but non-significantly higher in men(n=2849)than women(n=3769,1.30%vs.0.96%,P=0.19)and in current drinkers(n=793)than never drinkers(n=5825,1.64%vs.1.03%,P=0.12).In both unadjusted and adjusted analyses,there was interaction between sex and current alcohol intake in relation to the incidence of atrial fibrillation(P<0.0001).After adjustment for confounding factors,current drinkers had a significantly higher incidence rate of atrial fibrillation than never drinkers in women(12.96%[7/54]vs.0.78%[29/3715],adjusted odds ratio[OR]=10.25,95%confidence interval[CI]:3.54−29.67,P<0.0001),but not in men(0.81%[6/739]vs.1.47%[31/2110],OR=0.62,95%CI:0.25−1.51,P=0.29).CONCLUSIONS Our study showed a significant association between alcohol intake and the incidence of atrial fibrillation in elderly Chinese women,but not men.

为研究不同负压对铝镁贫氧推进剂的点火及燃烧特性的影响,在负压环境下(0.01,0.02,0.04,0.06,0.08,0.1 MPa)和不同热流下(1.26,1.86,2.23,2.79 W·mm^(-2))采用CO_2激光点火系统对铝镁贫氧推进剂进行点火实验,使用高速摄影仪记录点火燃烧过程,使用两个光电二极管同时监测激光和火焰信号得到其点火延迟时间,研究了负压对推进剂点火延迟时间、燃烧过程和燃速的影响。结果表明,压强影响推进剂热解气体的扩散,压强为0.08 MPa时,初焰为圆柱状,随着压强降低至0.02 MPa,初焰为圆球状;随着压强的降低,推进剂点火延迟时间增加,但随着热流密度的增大,压强对点火延迟时间的影响显著降低;压强对推进剂燃速影响较大,随着压强的降低,推进剂燃速降低,当压强从0.1 MPa降至0.01 MPa时,燃速降低47%;同时,在负压环境下,Vielle燃速公式更适用于表征铝镁贫氧推进剂的燃速特性。

目的探讨单纯夜间高血压与左室肥厚的关系。方法在浙江省景宁县14个村的居民中，记录24h血压和12导联心电图。结果647例受检者中单纯夜间高血压[平均血压≥120／70mmHg（1mmHg=0．133kPa）]有72例（11．1％）。夜州和白天的收缩压或舒张压都是左室肥厚的独立影响因素（P〈0．01）。但单纯夜间高血压患者左室肥厚的患病率（23．6％）与正常血压者（17．4％）相比，差异无统计学意义（P=0．24）。结论在本横断面研究中，单纯夜间高血压与用心电图诊断的左室肥厚没有显著独立关联。
