Wearable Battery-Free Perspiration Analyzing Sites Based on Sweat Flowing on ZnO Nanoarrays

We fabricated wearable perspiration analyzing sites for actively monitoring physiological status during exercises without any batteries or other power supply.The device mainly consists of ZnO nanowire(NW)arrays and flexible polydimethylsiloxane substrate.Sweat on the skin can flow into the flow channels of the device through capillary action and flow along the channels to ZnO NWs.The sweat flowing on the NWs(with lactate oxidase modification)can output a DC electrical signal,and the outputting voltage is dependent on the lactate concentration in the sweat as the biosensing signal.ZnO NWs generate electric double layer(EDL)in sweat,which causes a potential difference between the upper and lower ends(hydrovoltaic effect).The product of the enzymatic reaction can adjust the EDL and influence the output.This device can be integrated with wireless transmitter and may have potential application in constructing sports big data.This work promotes the development of next generation of biosensors and expands the scope of self-powered physiological monitoring system.

Analyzing Bandwidth on the Microwave Absorber by the Interface Reflection Model

Metallic flaky sendust particles are prepared for use as fillers in electromagnetic attenuation composites. We report the interface reflection model to divide the broad bandwidth into electromagnetic loss and quarter-wavelength （λ/4） cancelation. Combining with the face reflection calculation, we identify the electromagnetic loss originated from skin effect, which is used to explain over half of the absorbed energy in high frequency band. Most impor- tantly, the unique electromagnetic loss cannot generate the reflection loss （RL） peak. Using the phase relation of face reflection, we show evidence that the λ/4 cancelation is vital to generate the RL peak. The calculated energy loss agrees well with the experimental data and lays the foundation for further research.

Granular analyzing of weapon SoS demand description

The systematism of weapon combat is the typical characteristic of a modern battlefield. The process of combat is complex and the demand description of weapon system of systems （SOS） is difficult. Granular analyzing is an important method for solving the complex problem in the world. Granular thinking is introduced into the demand description of weapon SoS. Granular computing and granular combination based on a relation of compatibility is proposed. Based on the level of degree and degree of detail, the granular resolution of weapon SoS is defined and an example is illustrated at the end.

Dual Space Analyzing Based on Symmetry Properties for Phonons of Si Quantum Dot

Phonon modes in spherical Si quantum dots (QDs) with up to 7.9 nm in diameter are calculated by using the projection operators of the group theory into valence force field model. The phonons of dot modes in each of five irreducible representations (symmetries) are classified by using a dual space analysis method. It is found that the bulk-like modes with localization radius much smaller than the dot's radius have clearly pronounced bulk specific-κdefinite bulk band (one in six modes). In Si dots of all sizes, each specific bulk-like dot mode has specific symmetry.TO dot modes and bulk-like X-derived TA and LA dot modes red-shift in frequency with decreasing dot size. There is almost not LO/TO mixing for bulk-like modes. As for the surface-like modes localized at the periphery of the dot,their eigenmodes have not a dominant bulk specific-κ point parentage or a dominant BZ parentage around some special point. They are a superposition of many bulk bands with κ from all over the bulk BZ. They have much significant mode mixing than the bulk-like phonons. The classification of dot modes based on the symmetry of group theory will bring advantageous to the discussion of Ramam spectrum, electron-phonon interaction and other phonon-assisted effects in QDs.

Comparisons of Criteria for Analyzing the Dynamical Association of Solutes in Aqueous Solutions

How to determine accurately the association states of solutes in aqueous systems is of fundamental importance in a variety of chemical, physical, and biological processes, We apply four widely used criteria to analyze the dynamic association processes of solutes, e.g., amphiphilic molecules, and to find the inappropriate selections of representative sites on solutes in these criteria may bring about appreciable influence on the estimation of dynamic association behaviors such as unrealistic packing radii and even misleading packing structures. It would be better to select dynamically representative sites on solute molecules based on the characteristic of solute associations. Our detailed discussions give a guide on how to determine an appropriate criterion to accurately analyze the association behaviors of solute molecules in aqueous solutions.

On modeling and analyzing multi-agent systems using π-calculus

Dynamic architecture of multi-agent systems （MAS） is important for critical systems. As the existing formal specifications of MAS cannot describe its dynamic architecture, a formal approach using n-calculus is presented, which is suited for the describing and analyzing of concurrent MAS with dynamic topology, n-calculus describes the belief-desireintention （BDI） model that represents agent＇s mental states and provides many useful facilities to analyze MAS model such as deadlock, behavior equivalence, and model checking. To illustrate the favorable representation capability of n-calculus, an example of dynamic multi-agent systems in e-commerce is provided. Finally, by using an existing n-calculus supporting tool, MAS model and some key behaviors properties are analyzed and verified.

A Decision Support System for Analyzing and Evaluating Merger and Acquisition Strategies

A computer aided decision support system (merger and acquisition analyzing and evaluating-decision support system (MAAE-DSS)) for analyzing and evaluating corporate merger and acquisition (M&A) strategies, was proposed. Strategic management tools such as scale index-market growth rate matrix (S-M matrix), industrial attraction-corporate strength matrix (I-S matrix), market growth rate-market occupancy matrix (G-O matrix), and life cycle-competitive position matrix (L-C matrix), were applied in the MAAE-DSS with its own data base (DB), model base (MB), method base (MeB), and knowledge base (KB), in order to support the management bureau in the formulation of M&A strategies.

Analyzing the role of extracellular matrix during nervous system development to advance new regenerative strategies

Regeneration in the central nervous system （CNS） is limited, and CNS damage often leads to cognitive impairment or permanent functional motor and sensory loss. Impaired regenerative capacity is multifactorial and includes inflammation, loss of the blood-brain barrier, and alteration in the extracellular matrix （ECM）. One of the main problems is the formation of a glial scar and the production of inhibitory ECM, such as proteoglycans, that generates a physical and mechanical barrier, impeding axonal regrowth （Figure 1A）.

Analyzing Concepts of Human Rights with an Asian Accent

Let＇s suppose we were in the early Twentieth Century, trying to answer the ques- tion： What will be the mostimportant things that will happen in this century？ You may think about the ＂rise of the United States,＂ or the long-lived British Empire. The development of new energy might have come to mind as well. However, you may neither have imagined the invention of nuclear weapons, nor the development of space technol- ogy. Few may have anticipated the establishment of communist regimes and the rise of democracy later.

千岛湖水体稳定度和热分层结构对溶解氧垂向分布的影响

基于2017年1月—2020年2月千岛湖大坝前水质高频监测数据与湖心区气象数据,使用Lake Analyzer(LA)软件计算了水体稳定度指标(“施密特稳定度”和“浮力频率”)和热分层指标(“温跃层深度”和“温跃层厚度”),并与溶解氧垂向分布指标(“氧跃层深度”和“氧跃层强度”)结合分析。结果表明千岛湖存在时间长且稳定的热力分层和溶解氧分层,分层期为每年4—12月,根据结构变化可分为形成期(4—6月)、稳定期(7—9月)和减弱期(10—12月)三个阶段。水体稳定度指标、热分层指标和溶解氧垂向分布指标间相关分析结果表明:水体混合状态是影响溶解氧垂向分布的重要因素,湖体存在热分层则是氧跃层出现的根本原因,水体稳定度升高与热分层结构形成均阻碍溶解氧的垂向交换,促进氧跃层的形成。基于回归分析,发现温跃层深度与氧跃层深度具有良好的线性关系,拟合精度高(R^(2)=0.81,N=25),说明在千岛湖可通过温跃层深度推断氧跃层态势。研究结果同时证明LA在千岛湖的可适用性,以及在其它湖泊的可推广性,提供了水体稳定度和热分层指标定量化计算的工具。
