There are many techniques using sensors and wearable devices for detecting and monitoring patients with Parkinson’s disease(Pd).A recent development is the utilization of human interaction with computer keyboards for analyzing and identifying motor signs in the early stages of the *** designs for classification of time series of computer-key hold durations recorded from healthy control and Pd subjects require the time series of length to be considerably *** an attempt to avoid discomfort to participants in performing long physical tasks for data recording,this paper introduces the use of fuzzy recurrence plots of very short time series as input data for the machine training and classification with long short-term memory(LSTM)neural *** an original approach that is able to both significantly increase the feature dimensions and provides the property of deterministic dynamical systems of very short time series for information processing carried out by an LSTM layer architecture,fuzzy recurrence plots provide promising results and outperform the direct input of the time series for the classification of healthy control and early Pd subjects.

提出了用于热塑性聚合物板材的柔性成形技术——多点热成形技术。根据高温单向拉伸试验数据确定了不同温度下聚碳酸酯(PC)板材的超弹性材料模型参数。运用有限元软件Abaqus对不同温度和不同成形压力下的PC板材多点热成形过程进行了数值模拟,结果表明:当成形温度与成形压力分别为160℃和10 kPa时,成形件平均形状误差最小。参照数值模拟结果进行了PC板材的多点热成形试验,验证了数值模拟结果的准确性。测量并分析了成形件的成形精度,结果表明:成形件具有较高的成形精度,可以满足工程应用需要。

The objective of this study is to develop a novel and efficient model for forecasting the nonlinear behavior of structures in response to time-varying random *** key idea is to design a deep learning architecture to leverage the relationships,between external excitations and structure's vibration signals,and between historical values and future values,within multiple time-series *** proposed method consists of two main steps:the first step applies a global attention mechanism to combine multiple-measured time series and time-varying excitation into a weighted time series before feeding it to a temporal architecture;the second step utilizes a self-attention mechanism followed by a fully connected layer to predict multi-step future *** viability of the proposed method is demonstrated via two case studies involving synthetic data from a three-dimensional(3d)reinforced concrete structure and experimental data from an 18-story steel ***,comparison and robustness studies are carried out,showing that the proposed method outperforms conventional methods and maintains high performance in the presence of noise with an amplitude of less than 10%.

Urea-assisted natural seawater electrolysis is an emerging technology that is effective for grid-scale carbon-neutral hydrogen mass production yet *** scaling relations is an effective strategy to break through the bottleneck of natural seawater ***,by dFT calculation,we demonstrated that the interface boundaries between Ni_(2)P and MoO_(2) play an essential role in the selfrelaxation of the Ni-O interfacial bond,effectively modulating a coordination number of intermediates to control independently their adsorption-free energy,thus circumventing the adsorption-energy scaling *** this conceptual model,a well-defined 3d F-doped Ni_(2)P-MoO_(2) heterostructure microrod array was rationally designed via an interfacial engineering strategy toward urea-assisted natural seawater *** a result,the F-Ni_(2)P-MoO_(2) exhibits eminently active and durable bifunctional catalysts for both HER and OER in acid,alkaline,and alkaline sea water-based *** in-situ analysis,we found that a thin amorphous layer of NiOOH,which is evolved from the Ni_(2)P during anodic reaction,is real catalytic active sites for the OER and UOR ***,such electrode-assembled urea-assisted natural seawater electrolyzer requires low voltages of 1.29 and 1.75 V to drive 10 and600 mA cm^(-2)and demonstrates superior durability by operating continuously for 100 h at 100 mA cm^(-2),beyond commercial Pt/C||RuO_(2) and most previous reports.

日前。发表在Scientific Reports杂志上的一篇研究报告中，来自加利福尼亚大学等机构的研究人员通过利用一种由石墨烯组成的新型传感器深入解析了线粒体的程序性细胞死亡过程，该研究或为驱动癌细胞自我毁灭提供了新的线索。研究者通过研究开发了一种监测线粒体改变的电子学方法，该方法能够指示出细胞进行自我毁灭的开始阶段，我们机体每个细胞中都有数百个、甚至数千个线粒体。每个线粒体都有着内膜和外膜结构；作为细胞的能量工厂，线粒体会对细胞中的碳水化合物和脂肪进行代谢产能以便细胞利用并且储存。但同时线粒体还有第二个角色，那就是调节细胞的生死通路。
