In order to study the effective electromagnetic properties of heterogeneous materials, computation of very large 3D RC (resistor-capacitor) network model is indispensable. The huge computations and long time-consuming exist in previous sequential algorithm, which hinder the widely application of the model. A novel par…

Good UV transmittance and some scintillation light are two requirements for materials to be used to construct a homogeneous hadron calorimeter (HHCAL) capable to measure both Cherenkov and Scintillation light. In this paper we report an investigation on lead based halide crystals for the HHCAL detector concept, includ…
Compartmental modeling of dynamic PET data enables quantification of tracer kinetics in vivo, through the obtained model parameters. The dynamic data is sorted into frames during or after the acquisition, with a sampling interval usually ranging from 10 s to 300 s. In this study we wanted to investigate the effect of…

We employed both theoretical calculations and experiments to study the nonlinear responses in optical metamaterials. The spectra of second-harmonic generations measured on a fishnet metamaterial are in quantitative agreements with calculations based on full-wave numerical simulations combined with field integrations,…
The quality of service indicators in distribution networks represents a main concern in the power industry nowadays, and the power quality measurements (PQ) are an important part to obtain these indicators. When a PQ disturbance is detected and measured it has to be characterized to obtain the parametric data related…
The authors of this article have described the proposed modification of the Sheynin's method of weight estimation optimization.
In view of a particular GIS structure, a new type of planar antenna with extremely wide bandwidth is introduced. Due to the analysis of the relationship between antenna impedance and bandwidth, the investigated antenna bandwidth is broadened. The influence of dimension on antenna VSWR is optimized by using the simulat…
Metamaterials after years of development, in various fields shows its unique charm. This paper, based on the FSS with random distributed patches, combined with digital camouflage, proposes a model for processing realize multiband stealth realization. It not only reserved the digital camouflage of visible light stealth…
Abstract Superhydrophobic surfaces use a combination of microstructural surface patterning and a naturally hydrophobic surface to attain very high contact angles (θ > 150°). The interplay between these variables affects the macroscale characteristics of the surface. This manuscript presents a method for modeling a wid…

Objectives In recent years, the development of thrombolysis and percutaneous coronary intervention (PCI) have positive impacts on outcome of the patients with acute myocardial infarction (AMI), but the reperfusion injury followed by these treatments per se would lower the benefit. After carrying on a large amount of r…
Selectivity-determining steps for ethylene hydroformylation, i.e., ethyl hydrogenation versus CO insertion on Rh(111) and Rh@Cu(111) surfaces were investigated by density functional theory calculations. Compared with the Rh(111) surface, the Rh@Cu(111) surface decreases the hydrogenation barrier by 0.12 eV and more si…
The change mesomechanism of split tensile strength of concrete deteriorated by soft water was analyzed based on meso-fracture mechanics and experimental results.A special device was designed to simulate the leaching of concrete caused by soft water.Some experiments were conducted to test the porosity and the split ten…
摘要： 制备了石墨烯(CRG)-壳聚糖(CS)修饰玻碳(CRG-CS/GC)电极，用循环伏安法和示差脉冲伏安法研究了五氯酚(PCP)的电化学行为，发现其氧化电流信号与GC电极相比明显增强，表明修饰电极对PCP具有较强的吸附作用，并能够加速电子传递。 建立了一种灵敏简便、重现性好、稳定性好的测定PCP的新修饰电极方法，线性响应范围为1.00×10-7~1.00×10-5 mol/L（R=0.9975），检测限为2.3×10-8 mol/L(S/N=3)。 将该修饰电极应用于实际水样分析，回收率为97%~103%。
