Headings of UCAV Based on Nash Equilibrium

Given n vertices in a plane and UCAV going through each vertex once and only once and then coming back,the objective is to find the direction (heading) of motion in each vertex to minimize the smooth path of bounded curvature.This paper studies the headings of UCAV.First,the optimal headings for two vertices were given.On this basis,an n-player two-strategy game theoretic model was established.In addition,in order to obtain the mixed Nash equilibrium efficiently,n linear equations were set up.The simulation results demonstrated that the headings given in this paper are effective.
Optimal Active Power Dispatching of Microgrid and Distribution Network Based on Model Predictive Control

First, a three-tier coordinated scheduling system consisting of a distribution network dispatch layer, a microgrid centralized control layer, and local control layer in the energy internet is proposed. The multi-time scale optimal scheduling of the microgrid based on Model Predictive Control (MPC) is then studied, and the optimized genetic algorithm and the microgrid multi-time rolling optimization strategy are used to optimize the datahead scheduling phase and the intra-day optimization phase. Next, based on the three-tier coordinated scheduling architecture, the operation loss model of the distribution network is solved using the improved branch current forward-generation method and the genetic algorithm. The optimal scheduling of the distribution network layer is then completed. Finally, the simulation examples are used to compare and verify the validity of the method.
Energy Management System Design and Testing for Smart Buildings Under Uncertain Generation (Wind/Photovoltaic) and Demand

This study provides details of the energy management architecture used in the Goldwind microgrid test bed. A complete mathematical model, including all constraints and objectives, for microgrid operational management is first described using a modified prediction interval scheme. Forecasting results are then achieved every 10 min using the modified fuzzy prediction interval model, which is trained by particle swarm optimization. A scenario set is also generated using an unserved power profile and coverage grades of forecasting to compare the feasibility of the proposed method with that of the deterministic approach. The worst case operating points are achieved by the scenario with the maximum transaction cost. In summary, selection of the maximum transaction operating point from all the scenarios provides a cushion against uncertainties in renewable generation and load demand.
Color image encryption scheme based on chaotic systems

To improve the security of the color image encryption scheme,a color image encryption scheme based on chaotic systems is proposed. Firstly,the proposed scheme sets the color image as a three-dimensional matrix which is scrambled by affine transformation. Second,the Logistic chaotic sequence applied to generate the control parameter and auxiliary key is used to encrypt the three-dimensional matrix. Here,we mainly focus on two methods for encryption processes. One is to generate a chaotic sequence by Logistic map and Henon map,which is used to perform XOR operation with the scrambled components R',G',B' respectively. The other one is to adopt a binary Logistic sequence to select the pixel position for the scrambled components R',G',B' image,and then applying the Henon map and Logistic map with the auxiliary key to perform the replacement encryption. Based on this,an encrypted image is synthesized. Simulation results show that the proposed image encryption scheme can implement better encryption and achieve higher security performance.
Optimizing the fabrication of carbon nanotube electrode for effective capacitive deionization via electrophoretic deposition strategy

In order to obtain superior electrode performances in capacitive deionization (CDI), the electrophoretic deposition (EPD) was introduced as a novel strategy for the fabrication of carbon nanotube (CNT) electrode. Preparation parameters, including the concentration of slurry components, deposition time and electric field intensity, were mainly investigated and optimized in terms of electrochemical characteristic and desalination performance of the deposited CNT electrode. The SEM image shows that the CNT material was deposited homogeneously on the current collector and a non-crack surface of the electrode was obtained. An optimal preparation condition of the deposited CNT electrode was obtained and specified as the Al (NO_3)_3 M concentration of 1.3×10~(–2) mol/L, the deposition time of 30 min and the electric field intensity of 15 V/cm. The obtained electrode performs an increasing specific mass capacitance of 33.36 F/g and specific adsorption capacity of 23.93 mg/g, which are 1.62 and 1.85 times those of the coated electrode respectively. The good performance of the deposited CNT electrode indicates the promising application of the EPD methodology in subsequent research and fabrication of the CDI electrodes for CDI process.
Walking Access Distance of Metro Passengers and Relationship with Demographic Characteristics: A Case Study of Nanjing Metro

In the metropolises of China, the metro plays an increasingly important role in commuting because of its efficiency, affordability, and cleanliness. This paper attempts to explore the relationship between walking access distance to metro stations and the demographic characteristics of passengers, such as age, monthly income, travel frequency, gender, and travel purpose, as well as the influence of the urban context. Nanjing Metro Line 2 is selected as the case study. By using different methods such as a questionnaire survey, spatial decay function, analysis of covariance (ANOVA), network analysis of routes, and K-means cluster analysis, it is suggested that demographic characteristics have a significant impact on the pedestrian walking distance, with the exception of gender. Furthermore, the paper finds a spatial decay effect in walking access distance, the decay rate of which, however, varies across stations. Terminal stations have a larger pedestrian catchment area than in regular and exchange stations. Moreover, the passengers of Nanjing Metro Line 2 can be classified into six groups according to their demographic characteristics, among which education and occupation are vital indicators in determining their willingness to walk to the stations. Middle-class passengers have a higher dependence on the metro and tend to walk longer than other groups do. This study provides an important reference for planners and transport sectors to optimize land-use and transport infrastructures.
MXene–2D layered electrode materials for energy storage

As promising candidates of power resources, electrochemical energy storage (EES) devices have drawn more and more attention due to their ease of use, environmental friendliness, and high transformation efficiency. The performances of EES devices, such as lithium-ion batteries, sodium-ion batteries, and supercapacitors, depend largely on the inherent properties of electrode materials. On account of the outstanding properties of graphene, a lot of studies have been carried out on two-dimensional (2D) materials. Over the past few years, a new exfoliation method has been utilized to successfully prepare a new family of 2D transition metal carbides, nitrides, and carbonitrides, termed MXene, from layered precursors. Moreover, some unique EES properties of MXene have been discovered. With rapid research progress on this field, a timely account about the applications of MXene in the EES fields is highly necessary. In this article, the research progress on the preparation, electrochemical performance, and mechanism analysis of MXene is summarized and discussed. We also propose some personal prospects for the further development of this field.
Functionalization of graphene materials by heteroatom-doping for energy conversion and storage

Recent development in nanoscience and nanotechnology has opened up new frontiers in materials science and engineering to create new materials for energy generation and storage. Owing to their earth abundance, lowcost, structural tunability, large-surface area, and unique physicochemical properties, graphitic carbon materials have attracted a great deal of attention for energy-related applications. However, the pristine graphene materials without functionalization is intractable (insoluble and infusible), which has hindered their practical applications. Therefore, considerable research effort has been devoted to the development of functionalized graphene materials with desirable properties for specific applications, including energy conversion and storage. It was demonstrated that functionalized graphene materials with tunable work functions were useful as charge-extraction materials to effectively improve solar cell performance while those with high electrocatalytic activities could be used as metal-free catalysts in fuel cells, metal-air batteries, water splitting and integrated energy systems. This article provides a timely focused review on the development of heteroatom-doped graphene materials for low-cost, but efficient, energy generation and storage.
Triboelectric nanogenerator as a new technology for effective PM2.5 removing with zero ozone emission

Particles matters (PMs) have raised serious concerns due to their great impact on human health. Coupling triboelectric effect and electrostatic induction, triboelectric nanogenerator (TENG) has demonstrated as a practical sustainable power source for portable devices. The characteristics of TENG, such as high electric field and high output power, make it a promising technology in air cleaning applications. Here, the mechanism of the TENG and its application in self-powered air cleaning technologies are reviewed. Using the TENG as a voltage source, a self-powered air cleaning system for removing SO_2 and PMs is developed; and the removal efficiency of nanofiber filters is greatly enhanced due to electrostatic attraction. More importantly, the technology is not only most effective for removing nano-scale particles that cannot be effectively filtered using conventional fiber-film filters, but also produces no ozone emission. Besides being an independent power supply, a vibration TENG based triboelectric filter is designed to effectively capture the PMs from automobile exhaust fumes. Hence, the TENG demonstrates its great potential in self-powered air cleaning applications.
Successful Resuscitation with Extracorporeal Membrane Oxygenation in a Case with Prolonged Cardiac Arrest

This case study describes a 25-year-old patient who had a witnessed cardiac arrest in the medical intensive care unit. The patient received 107 minutes of cardiopulmonary resuscitation before the veno-arterial extracorporeal membrane oxygenation was initiated. During extracorporeal life support, the patient's cardiac function improved. The patient was weaned from extracorporeal membrane oxygenation on day 6 and was discharged without physical and neurological complications on day 28. The successful resuscitation in this case attributed to high-quality CCPR and timely ECMO support.
Glycopeptide ligation via direct aminolysis of selenoester

Direct aminolysis of selenoester in aqueous media was investigated as a glycopeptide ligation strategy. This strategy allows the peptide and glycopeptide ligation to proceed smoothly (even with hindered amino acids) without the need of cysteine residue, N-terminal thiol auxiliary or coupling additive, and to afford the corresponding amide products in excellent yields. No epimerization was observed during ligation reations. In this work, the selenoester of unprotected glycopeptide was readily prepared, and the direct aminolysis of glycopeptide selenoester was successfully applied to synthesize MUC1 mucin sequence efficiently.

Boron-assisted growth of silica nanowire arrays and silica microflowers for bendable capacitor application

Aligned silica nanowire arrays and silica microflowers were fabricated using boron as the catalyst and under the flow N_2 gas. The obtained product had no catalyst contamination. And silica nanowires had long lengths of a few hundreds. The growth of nanowire arrays and microflowers was explained using mechanism. Parallel-plate capacitors using silica nanowire mat as the dielectric were fabricated. The silica nanowire capacitor shows a specific capacitance of 0.24 nF/cm~2 at the frequency of 100 Hz. The capacitor is not monotone changing with the frequency. The measurement of mechanical properties shows that the tunneling current increases along with an increase in bending angle of the capacitor.
Fabrication of Fe-doped Co-MOF with mesoporous structure for the optimization of supercapacitor performances

The synergy effect between different components has attracted widespread attentions because of improved activity, selectivity and stability than single component. In this paper, we fabricated mesoporous hybrid dual-metal Co and Fe containing metallic organic framework (Co/Fe-MOF), Fe-MOF, and Co-MOF in the ionic liquid (IL)/supercritical CO_2 (SC)/surfactant emulsion system, and then studied the electrochemical properties of the three MOFs systematically. Experiment results indicate that, by taking advantages of coexistence of double metal, hybrid bi-metal Co/Fe-MOF exhibits the highest specific capacitance and the best cycling stability, with specific capacitance to 319.5 F/g at 1 A/g,1.4 and 4 times for single Co-MOF and Fe-MOF, respectively.

Remarkably the obtained composite shows 1105.2 mAh/g at a current density of 5000 mA/g after 400 cycles which makes it a promising candidate to improve the volumetric energy density.
Impact of surface hydroxylation in MgO-/SnO-nanocluster modified TiO_2 anatase (101) composites on visible light absorption, charge separation and reducibility

Surface modification with metal oxide nanoclusters has emerged as a candidate for the enhancement of the photocatalytic activity of titanium dioxide. An increase in visible light absorption and the suppression of charge carrier recombination are necessary to improve the efficiency. We have studied Mg_4O_4 and Sn_4O_4 nanoclusters modifying the (101)surface of anatase TiO_2 using density functional theory corrected for on-site Coulomb interactions (DFT + U). Such studies typically focus on the pristine surface, free of the point defects and surface hydroxyls present in real surfaces.We have also examined the impact of partial hydroxylation of the anatase surface on a variety of outcomes such as nanocluster adsorption, light absorption, charge separation and reducibility. Our results indicate that the modifiers adsorb strongly at the surface, irrespective of the presence of hydroxyl groups, and that modification extends light absorption into the visible range while enhancing UV activity. Our model for the excited state of the heterostructures demonstrates that photoexcited electrons and holes are separated onto the TiO_2 surface and metal oxide nanocluster respectively. Comparisons with bare TiO_2 and other TiO_2-based photocatalyst materials are presented throughout.
Implantation-decay method to study the β-delayed charged particle decay

In this paper, the implantation-decay method is introduced to study the β-delayed charged particle decay. A silicon detector array was used for the implantation of the incident beams and for the detection of the emitted particles. An experimental measurement on the β-delayed particle emission from ~(22)Al was used to demonstrate the method. The half-life value, charged particle spectroscopy, γ ray spectrum, and γ particle coincidence for the decay process were obtained and compared with previous experimental results for ~(22)Al. The results show that the implantation-decay method, using a silicon detector array, is a suitable experimental method to study the β-delayed charged particle decay for proton-rich nuclei.
3 μm厚切片在乳腺癌HER-2扩增检测中的可行性探讨

乳腺癌HER-2基因扩增是曲妥珠单抗赫赛汀(Herceptin)靶向治疗和辅助治疗的重要参考指标[1- 2],能有效延长患者的生存期,降低复发率[3]。用于诊断HER-2状态的最常用技术是免疫组化法检测HER-2蛋白水平和荧光原位杂交法(fluorescence in situ hybridization,FISH)检测HER-2 DNA水平,其中FISH法是检测扩增的“金标准”[4]。目前,临床上采用的比较经济实用的模式是免疫组化法初检+ HER-2蛋白2+者FISH检测[5]。2013版ASCO/CAP和2014版中国乳腺癌HER-2检测指南对FISH检测石蜡包埋组织时切片厚度提出的要求为4~ 5 μm[6- 7],但实际工作中发现切片厚度选择3 μm时对于直径小的肿瘤细胞来说更易单层平铺,更易出现连续的可观察区域。HER-2检测试剂盒说明书中明确提出,要选取核边界完整、探针和DAPI染色均匀、无重叠的细胞计数,避开需要主观辨别的细胞区域。本实验选取114例HER-2蛋白2+的乳腺浸润性导管癌石蜡包埋组织,采用3和5 μm两种厚度切片,探讨这两种切片厚度对FISH报告中HER-2基因是否扩增和CH17倍体结论的影响,尝试性分析3 μm厚度切片在FISH检测中的可行性。

Structure and Performance of Fe–N_x–C Catalyst for Oxygen Reduction Reaction Prepared by Vacuum Casting Method and the Second Pyrolysis

Affordable non-precious metal (NPM)catalysts played a vital role in the wide application of polymer electrolyte membrane fuel cells (PEMFC). In current work, a facile vacuum casting reacting method based on vacuum casting was introduced to prepare Fe–N_x–C oxygen reduction reaction (ORR)catalysts with high efficient in acid medium. The catalysts were prepared with ammonium ferrous sulfate hexahydrate (AFS)and 1,10-phenanthroline monohydrate utilizing homemade mesoporous silica template. The heat treatment and its influence on structure and performance were systematically evaluated to achieve superior ORR performance and some clues were found. And 850 ℃ was found to be the best temperature for the first and second pyrolysis. The linear sweep voltammetry (LSV)results showed that there were only 18 mV slightly negative shifts of half-wave potential (E1/2)of the optimal catalyst (749 mV)compared with the commercial Pt/C (20 μg·Pt·cm~(-2)). Besides, I850R also showed better electrochemical stability and methanol-tolerance than that of Pt/C. All evidences proved that our vacuum casting reacting strategy and heat treatment process were prospective for the future R&D of high performance Fe–Nx–C ORR catalysts.
On the Motion of Shear-Thinning Heat-Conducting Incompressible Fluid-Rigid System

The full Navier-Stokes-Fourier system with mixed boundary condition that describes the motion of shear-thinning and incompressible viscous fluid in a rotating multi-screw extruder is investigated. The viscosity is assumed to depend on the shear rate and the temperature. The global existence of suitable weak solutions is established. The fictitious domain method which consists in filling the moving rigid screws with the surrounding fluid and taking into account the boundary conditions on these bodies by introducing a well-chosen distribution of boundary forces is used.
Effects of turbulence on carbon emission in shallow lakes

Turbulent mixing is enhanced in shallow lakes.As a result,exchanges across the air–water and sediment–water interfaces are increased,causing these systems to be large sources of greenhouse gases.This study investigated the effects of turbulence on carbon dioxide (CO_2) and methane (CH_4) emissions in shallow lakes using simulated mesocosm experiments.Results demonstrated that turbulence increased CO_2 emissions,while simultaneously decreasing CH_4 emissions by altering microbial processes.Under turbulent conditions,a greater fraction of organic carbon was recycled as CO_2 instead of CH_4,potentially reducing the net global warming effect because of the lower global warming potential of CO_2 relative to CH_4.The CH_4/CO_2 flux ratio was approximately 0.006 under turbulent conditions,but reached 0.078 in the control.The real-time quantitative PCR analysis indicated that methanogen abundance decreased and methanotroph abundance increased under turbulent conditions,inhibiting CH_4 production and favoring the oxidation of CH_4 to CO_2.These findings suggest that turbulence may play an important role in the global carbon cycle by limiting CH_4 emissions,thereby reducing the net global warming effect of shallow lakes.
Formation process and mechanism of humic acid-kaolin complex determined by carbamazepine sorption experiments and various characterization methods

To explore the formation process and mechanism of organic matter and organic-mineral complex underhumification andmineralization conditions,a series of samples including humic acid,kaolin,and humic acid-kaolin complex were prepared using a subcritical water treatment method (SWT) under specific temperature,pressure and reaction time conditions.HA was used as a surrogate for natural organic matter because it has a similar abundant pore structure,variety of carbon types,and chemical components.These samples were used in carbamazepine (CBZ) sorption experiments and characterized by a variety of techniques.The polymerization of humic acid under the conditions of increased temperature and pressure resulted in an increase in specific surface area and molecular quantity.In addition,the degree of aromaticity rose from 59.52%to 70.90%.These changes were consistent with the transformation from‘soft carbon' to ‘hard carbon' that occurs in nature.The results of sorption experiments confirmed the interaction between humic acid and kaolin from the difference between the predicted and actual Qe values.The conceptual model of humic acid-kaolin complex could be deduced and described as follows.Firstly,the aromatic components of humic acid preferentially combine with kaolin through the intercalation effect,which protects them from the treatment effects.Next,the free carboxyl groups and small aliphatic components of humic acid interact on the surface of kaolin,and these soft species transforminto dense carbon through cyclization and polymerization.As a result,humic acid-kaolin complex with a mineral core and dense outer carbonaceous patches were formed.
