临床须要更好的自动血压仪

自Scipione Riva-Rocfi于1896年报告血压计技术以来，水银血压计经过一个世纪的临床应用之后，现在受到威胁，有三个原因：（1）由于水银的毒性危险，环境污染，它有可能从医院被取缔使用；（2）现在已经可以获得准确的自动血压仪，来替换水银血压计；（3）随着24小时动态血压监测的进入临床和研究，人们更信任动态血压而不是偶测血压。在许多国家，水银温度计已被替换，在瑞典和荷兰，医院已不再允许用水银，但在其它欧洲国家，包括英国和爱尔兰，尚未接受将水银从医院禁止使用，因为尚无代替水银血压计的准确的变通办法。

心脏电生理学新概念（16）QT间期离散度研究现状

在不同导联QT间期不同这一现象早已被发现，但在很长时间内被归因于非同步记录引起的测量误差。只是在1985年Campbell和Cowan先前要用了12导联同步记录心电图后，才首先证明不是测量误差，而是一种规律性的现象，并提出了QT间期离散度（QT dispersion, QTd）的概念。Day等在1990年发现QTd增大与室性心律失常及猝死密切相关，并提出QTd可作为预测恶性室性心律失常及猝死的指标。随后的大量研究明确了QTd的重要临床意义，至今QTd已作为心肌复极不均匀性和电不稳定性的一个重要指标。

CyclinB_1、p34~(cdc2)在X射线诱导的K562细胞G_2期阻滞中的作用

细胞周期调控是机体维持细胞增殖有序性及基因组稳定性的关键，它的失控是肿瘤发生的重要原因之一，故细胞周期调控已成为近年来生命科学研究的热点课题。在包括理化因素在内的各种DNA损伤因素作用下，DNA受损伤的细胞通常通过细胞周期阻滞赢得足够的修复时间，不能修复的则通过凋亡去除。细胞周期阻滞包括G_1、G_2期阻滞，G_1期阻滞受p53、WAF1等基因的调控，而在缺失p53基因的K652细胞中，G_2期阻滞则占有主导地位。笔者在采用中等剂量电离辐射作用于K562细胞时发现，K562细胞被诱导发生G_2期阻滞，因G_2期调控机理的研究主要集中在以CyclinB、p34~(cdc2)为中心的调节通路，故我们进一步观察了有丝分裂促进因子(MPF)的两个组成单位CyclinB、p34~(cdc2)在G_2期阻滞中的作用以期为细胞周期调控的机理提供分子水平的依据。

Hydrothermal growth of hydroxyapatite and ZnO bilayered nanoarrays on magnesium alloy surface with antibacterial activities

Magnesium alloy (MgA) has been extensively used as orthopedic and cardiovascular scaffolds in virtue of its good biocompatibility, unique biodegradability and excellent mechanical properties. However, poor corrosion resistance and easy infection after implantation seriously limit the potential applications of MgA in the biomedical field. Herein, we fabricated bilayered nanoarrays of hydroxyapatite nanorods (HANRs) and ZnO nanorods (ZnONRs) onto the surface of MgA (MgA-MgO-HANRs- ZnONRs) via micro-arc oxidation (MAO) treatment, microwave-assisted hydrothermal and hydrothermal methods. The morphology and chemical composition of MgA-MgOHANRs- ZnONRs was characterized by FE-SEM, XRD and EDS, indicating that HANRs-ZnONRs bilayered nanoarrays were fabricated on the surface of MgA-MgO. The surface of MgA-MgO-HANRs-ZnONRs exhibited excellent hydrophilicity as evidenced by the low water contact angle of 3°. Compared with the original MgA, the corrosion resistance of MgA-MgO-HANRs-ZnONRs was obviously improved with decreasing the corrosive current density (i_(corr)) of 2 orders of magnitude. The MgA-MgOHANRs- ZnONRs performed excellent antibacterial properties with the bactericidal rate of 96.5% against S. aureus and 94.3% against E. coli.
Binding to m~6A RNA promotes YTHDF2- mediated phase separation

As one of the most abundant modifications on mRNA in mammal, N~6-methyladenosine(m~6A) has been demonstrated to play important roles in various biological processes including nuclear RNA export, mRNA splicing, miRNA processing, mRNA degradation and translation(Shi et al., 2019). Importantly, different m~6A reader proteins have been shown to play central roles in these processes.
Electrochemical Fabrication of rGO-embeddedAg-TiO_2 Nanoring/Nanotube Arrays for Plasmonic Solar Water Splitting

Effective utilization of hot electrons generated from the decay of surface plasmon resonance in metal nanoparticles is conductive to improve solar water splitting efficiency. Herein, Ag nanoparticles and reduced graphene oxide (rGO) co-decorated hierarchical TiO_2 nanoring/nanotube arrays (TiO_2 R/T) were facilely fabricated by using two-step electrochemical anodization, electrodeposition, and photoreduction methods. Comparative studies were conducted to elucidate the effects of rGO and Ag on the morphology, photoresponse, charge transfer, and photoelectric properties of TiO_2. Firstly, scanning electron microscope images confirm that the Ag nanoparticles adhered on TiO_2 R/T and TiO_2 R/T-rGO have similar diameter of 20 nm except for TiO_2 R-rGO/T. Then, the UV–Vis DRS and scatter spectra reveal that the optical property of the Ag-TiO_2 R/T-rGO ternary composite is enhanced, ascribing to the visible light absorption of plasmonic Ag nanoparticles and the weakening effect of rGO on light scattering. Meanwhile, intensity-modulated photocurrent spectroscopy and photoluminescence spectra demonstrate that rGO can promote the hot electrons transfer from Ag nanoparticles to Ti substrate, reducing the photogenerated electron– hole recombination. Finally, Ag-TiO_2 R/T-rGO photoanode exhibits high photocurrent density (0.98 mA cm–2) and photovoltage (0.90 V), and the stable H2 evolution rate of 413 μL h– 1 cm– 2 within 1.5 h under AM 1.5 which exceeds by 1.30 times than that of pristine TiO_2 R/T. In line with the above results, this work provides a reliable route synergizing rGO with plasmonic metal nanoparticles for photocatalysis, in which, rGO presents a broad absorption spectrum and effective photogenerated electrons transfer.
Optimizing the Performance of CsPbI3-BasedPerovskite Solar Cells via Doping a ZnO Electron Transport Layer Coupled with Interface Engineering

Interface engineering has been regarded as an effective and noninvasive means to optimize the performance of perovskite solar cells (PSCs). Here, doping engineering of a ZnO electron transport layer (ETL) and CsPbI3/ZnO interface engineering via introduction of an interfacial layer are employed to improve the performances of CsPbI3- based PSCs. The results show that when introducing a TiO_2 buffer layer while increasing the ZnO layer doping concentration, the open-circuit voltage, power conversion efficiency, and fill factor of the CsPbI3- based PSCs can be improved to 1.31 V, 21.06%, and 74.07%, respectively, which are superior to those of PSCs only modified by the TiO_2 buffer layer or high-concentration doping of ZnO layer. On the one hand, the buffer layer relieves the band bending and structural disorder of CsPbI3. On the other hand, the increased doping concentration of the ZnO layer improves the conductivity of the TiO_2/ZnO bilayer ETL because of the strong interaction between the TiO_2 and ZnO layers. However, such phenomena are not observed for those of a PCBM/ZnO bilayer ETL because of the weak interlayer interaction of the PCBM/ZnO interface. These results provide a comprehensive understanding of the CsPbI3/ZnO interface and suggest a guideline to design high-performance PSCs.
CNT/High Mass Loading MnO_2/Graphene-Grafted Carbon Cloth Electrodes for High-Energy Asymmetric Supercapacitors

Flexible supercapacitor electrodes with high mass loading are crucial for obtaining favorable electrochemical performance but still challenging due to sluggish electron and ion transport. Herein, rationally designed CNT/MnO_2/graphene-grafted carbon cloth electrodes are prepared by a “graft-deposit-coat” strategy. Due to the large surface area and good conductivity, graphene grafted on carbon cloth offers additional surface areas for the uniform deposition of MnO_2 (9.1 mg cm–2) and facilitates charge transfer. Meanwhile, the nanostructured MnO_2 provides abundant electroactive sites and short ion transport distance, and CNT coated on MnO_2 acts as interconnected conductive “highways” to accelerate the electron transport, significantly improving redox reaction kinetics. Benefiting from high mass loading of electroactive materials, favorable conductivity, and a porous structure, the electrode achieves large areal capacitances without compromising rate capability. The assembled asymmetric supercapacitor demonstrates a wide working voltage (2.2 V) and high energy density of 10.18 mWh cm–3.
Theoretical and Experimental Sets of Choice Anode/Cathode Architectonics for High-Performance Full-Scale LIB Built-up Models

To control the power hierarchy design of lithium-ion battery (LIB) builtup sets for electric vehicles (EVs), we offer intensive theoretical and experimental sets of choice anode/cathode architectonics that can be modulated in full-scale LIB built-up models. As primary structural tectonics, heterogeneous composite superstructures of full-cell-LIB (anode//cathode) electrodes were designed in closely packed flower agave rosettes TiO_2@C (FRTO@C anode) and vertical-star-tower LiFePO_4@C (VST@C cathode) building blocks to regulate the electron/ion movement in the three-dimensional axes and orientation pathways.The superpower hierarchy surfaces and multi-directional orientation components may create isosurface potential electrodes with mobile electron movements, in-to-out interplay electron dominances, and electron/charge cloud distributions.This study is the first to evaluate the hotkeys of choice anode/cathode architectonics to assemble different LIB–electrode platforms with high-mobility electron/ion flows and high-performance capacity functionalities.Density functional theory calculation revealed that the FRTO@C anode and VST-(i)@C cathode architectonics are a superior choice for the configuration of full-scale LIB built-up models.The integrated FRTO@C//VST-(i)@C full-scale LIB retains a huge discharge capacity (~ 94.2%), an average Coulombic efficiency of 99.85% after 2000 cycles at 1 C, and a high energy density of 127 Wh kg–1, thereby satisfying scale-up commercial EV requirements.
Bio-Derived Hierarchical Multicore–ShellFe_2N-Nanoparticle-Impregnated N-Doped Carbon Nanofiber Bundles: A Host Material for Lithium-/ Potassium-Ion Storage

Despite the significant progress in the fabrication of advanced electrode materials, complex control strategies and tedious processing are often involved for most targeted materials to tailor their compositions, morphologies, and chemistries. Inspired by the unique geometric structures of natural biomacromolecules together with their high affinities for metal species, we propose the use of skin collagen fibers for the template crafting of a novel multicore–shell Fe_2N– carbon framework anode configuration, composed of hierarchical N-doped carbon nanofiber bundles firmly embedded with Fe_2N nanoparticles (Fe_2N@N-CFBs).In the resultant heterostructure, the Fe_2N nanoparticles firmly confined inside the carbon shells are spatially isolated but electronically well connected by the long-range carbon nanofiber framework.This not only provides direct and continuous conductive pathways to facilitate electron/ion transport, but also helps cushion the volume expansion of the encapsulated Fe_2N to preserve the electrode microstructure.Considering its unique structural characteristics, Fe_2N@N-CFBs as an advanced anode material exhibits remarkable electrochemical performances for lithium- and potassium-ion batteries.Moreover, this bio-derived structural strategy can pave the way for novel low-cost and high-efficiency syntheses of metal-nitride/carbon nanofiber heterostructures for potential applications in energy-related fields and beyond.
Investment optimization of grid-scale energy storage for supporting different wind power utilization levels

With the large-scale integration of renewable generation, energy storage system(ESS) is increasingly regarded as a promising technology to provide sufficient flexibility for the safe and stable operation of power systems under uncertainty. This paper focuses on grid-scale ESS planning problems in transmission-constrained power systems considering uncertainties of wind power and load. A scenario-based chance-constrained ESS planning approach is proposed to address the joint planning of multiple technologies of ESS. Specifically, the chance constraints on wind curtailment are designed to ensure a certain level of wind power utilization for each wind farm in planning decision-making. Then, an easy-to-implement variant of Benders decomposition(BD) algorithm is developed to solve the resulting mixed-integer nonlinear programming problem. Our case studies on an IEEE test system indicate that the proposed approach can co-optimize multiple types of ESSs and provide flexible planning schemes to achieve the economic utilization of wind power. In addition, the proposed BD algorithm can improve the computational efficiency in solving this kind of chance-constrained problems.
Schedulable capacity forecasting for electric vehicles based on big data analysis

Fast and accurate forecasting of schedulable capacity of electric vehicles(EVs) plays an important role in enabling the integration of EVs into future smart grids as distributed energy storage systems. Traditional methods are insufficient to deal with large-scale actual schedulable capacity data. This paper proposes forecasting models for schedulable capacity of EVs through the parallel gradient boosting decision tree algorithm and big data analysis for multi-time scales. The time scale of these data analysis comprises the real time of one minute, ultra-short-term of one hour and one-day-ahead scale of 24 hours. The predicted results for different time scales can be used for various ancillary services. The proposed algorithm is validated using operation data of 521 EVs in the field. The results show that compared with other machine learning methods such as the parallel random forest algorithm and parallel k-nearest neighbor algorithm, the proposed algorithm requires less training time with better forecasting accuracy and analytical processing ability in big data environment.
Incentive-based demand response model for maximizing benefits of electricity retailers

The change of customer behaviors and the fluctuation of spot prices can affect the benefits of electricity retailers. To address this issue, an incentive-based demand response(DR) model involving the utility and elasticity of customers is proposed for maximizing the benefits of retailers. The benefits will increase by triggering an incentive price to influence customer behaviors to change their demand consumptions. The optimal reduction of customers is obtained by their own profit optimization model with a certain incentive price. Then, the sensitivity of incentive price on retailers' benefits is analyzed and the optimal incentive price is obtained according to the DR model. The case study verifies the effectiveness of the proposed model.
Analysis of unbalanced clustered voltage and control strategy of clustered voltage balancing for cascaded H-bridge STATCOM

To explore the clustered voltage balancing mechanism of the cascaded H-bridge static synchronous compensator(STATCOM), this paper analyzes the causes of unbalanced clustered voltage. The negative-sequence current caused by the compensation of unbalanced reactive power or detection and control errors and the zero-sequence voltage caused by voltage drift of the STATCOM neutral point contribute to unbalanced clustered voltage. On this basis, this paper proposes a control strategy to inject negative-sequence current and zero-sequence voltage simultaneously. The injection of negative-sequence current may cause current asymmetry in the grid, and the zerosequence injection has a relatively limited balancing ability in the clustered voltages. The proposed control strategy can not only generate a faster balancing response than the traditional zero-sequence voltage injection method, but also lower the extent of current asymmetry compared with the traditional negative-sequence current injection method. Then, the negative-sequence current and zero-sequence voltage injection are further transformed into the dq frame to establish a unified frame. The effectiveness of the proposed control strategy is verified by the simulation and experimental results.
