Two new high-nitrogen energetic compounds ZTO·2H2O and ZTO(phen)·H2O have been synthesized (where ZTO = 4,4-azo-1,2,4-triazol-5-one and phen = 1,10-phenanthroline). The crystal structure, elemental analysis and IR spectroscopy are presented. Compound 1 ZTO·2H2O crystallizes in the orthorhombic crystal system with space group Pnna and compound 2 ZTO(phen)·H2O in the triclinic crystal system with space group P-1. In ZTO(phen)·H2O, there is intermolecular hydrogen bonds between the -NH group of ZTO molecule (as donor) and N atom of phen molecule (as acceptor). Thermal decomposition process is studied by applying the differential scanning calorimetry (DSC) and thermo thermogravimetric differential analysis (TG-DTG). The DSC curve shows that there is one exothermic peak in ZTO·2H2O and ZTO(phen)·H2O, respectively. The critical temperature of thermal explosion (Tb) for ZTO·2H2O and ZTO(phen)·H2O is 282.21 oC and 195.94 oC, respectively.

Huang, Hua,Jin, Jie-Jie,Long, Zi-Wen,Wang, Wei,Cai, Hong,Liu, Xiao-Wen,Yu, Hong-Mei,Zhang, Li-Wen,Wang, Ya-Nong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.19

Gastric cancer continues to be a leading cause of cancer death. The majority of patients with gastric adenocarcinoma in China present with advanced disease. Ruling out unresectable cancers from an unnecessary "open" exploration is very important. The aim of this study was to assess the value of five-port anatomical laparoscopic exploration in T4 gastric cancer in comparison with three-port laparoscopic exploration and laparotomy exploration. We conducted a retrospective study on 126 patients with T4 stage scheduled for D2 curative gastrectomy based on computed tomography (CT) staging at Department of Gastric Cancer and Soft Tissue Sarcoma, Fudan University Shanghai Cancer Center, from Apr. 2011 to Apr. 2013. Laparotomy exploration (Group I), three-port laparoscopic exploration (Group II) or five-port anatomical laparoscopic exploration (Group III) were performed prior to radical gastrectomy. Accuracy rate for feasibility of D2 curative gastrectomy in laparotomy exploration and five-port anatomical laparoscopic exploration groups was higher than that in the three-port laparoscopic exploration group. Five-port anatomical laparoscopic exploration group had the highest accuracy resection rate (Group I vs Group II vs Group III,92.6% vs78.6% vs 97.7%; p<0.05) and shorter length of hospitalization (Group I vs Group II vs Group III, $9.58{\pm}4.17$ vs $6.13{\pm}2.85$ vs $5.00{\pm}1.81$; p<0.001). Three-port laparoscopic exploration has low accuracy rate for assessing feasibility of D2 curative gastrectomy and five-port anatomical laparoscopic exploration should be performed on patients with T4 gastric cancer.

Jie Huang,Jianfei Chen,Hongsheng Yang,Dongfang Li 제어·로봇·시스템학회 2023 International Journal of Control, Automation, and Vol.21 No.10

To improve the tracking efficiency of the platoon during driving and ensure the spacing safety between vehicles, a platoon tracking control strategy based on the adaptive neural network algorithm is developed. In this method, the nonlinear term in the vehicle model is estimated by the adaptive neural network, and the estimated value is used to compensate for the control input and enhance the tracking performance of the vehicle platoon. In addition, the estimation update law of target trajectory and adjacent vehicle acceleration is designed through the adaptive method, which relaxes the trajectory generation requirements of virtual vehicles, improves the tracking performance of vehicle platoon, reduces the measurement and communication burden in the platoon, and ensures the security and stability of vehicle platoon system. After constructing the vehicle and desired path model, the control objective is formulated, and the adaptive neural network algorithm controller is designed. Meanwhile, the stability of the controller is verified by the Lyapunov method. The feasibility of the proposed method is proved by simulation and experiment. Rigorous theoretical derivation and experiments confirm that the proposed strategy has obvious advantages over other existing strategies.

Jie Huang,Jian-Feng Zhu 대한수학회 2018 대한수학회보 Vol.55 No.5

Let $f=h+\overline{g}$ be a harmonic mapping of the unit disk $\mathbb D$ with the holomorphic part $h$ satisfying that $h$ is injective and $h(\mathbb D)$ is an $M$-linearly connected domain. In this paper, we obtain the sufficient and necessary conditions for $f$ to be bi-Lipschitz, which is in particular, quasiconformal. Moreover, some distortion theorems are also obtained.

Aeroelastic Simulation Using CFD/CSD Coupling Based on Precise Integration Method

Huang Chengde,Huang Jie,Song Xin,Zheng Guannan,Nie Xueyuan 한국항공우주학회 2020 International Journal of Aeronautical and Space Sc Vol.21 No.3

Aeroelasticity studies the interaction between the aerodynamic loads and the flexible structures, and has gained much attention in the design of modern aircraft. Most of the existing computational fluid dynamics/computational structural dynamics (CFD/CSD) coupling approaches are based on Runge–Kutta method, central difference method, linear multi-step method and so on, which are conditionally stable and are unsuitable for the stiff problem that requires a very small time step to solve. In this paper, the precise integration method (PIM) formula is derived for the structural modal equations and then the PIM-based CFD/CSD coupling method is presented. The three-dimensional AGARD wing 445.6 and a sweptback wing are considered here for aeroelastic studies. The flutter results demonstrate that the presented method is comparable in accuracy to the traditional strong coupling method and has better numerical stability property than some exiting improved methods. For the static aeroelastic analyses, applying a large damping ratio to the structural equations helps to obtain the equilibrium quickly but may lead to the stiff problem, which was seldom discussed before. The results show that the presented PIM-based coupling method can overcome the stiff problem arising in static aeroelastic systems and is more efficient than the traditional coupling approach based on Runge–Kutta method, especially when a large damping ratio is applied.

GNSS spoofing detection: Theoretical analysis and performance of the Ratio Test metric in open sky

Jie Huang,Letizia Lo Presti,Beatrice Motella,Marco Pini 한국통신학회 2016 ICT Express Vol.2 No.1

Nowadays more and more applications rely on the information provided by Global Navigation Satellite Systems (GNSSs), but the vulnerability of GNSS signals to interference, jamming and spoofing is a growing concern. Among all the possible sources of intentional interference, spoofing is extremely deceptive and sinister. In fact, the victim receiver may not be able to warn the user and discern between authentic and false signals. For this reason, a receiver featuring spoofing detection capabilities might become a need in many cases. Different types of spoofing detection algorithms have been presented in recent literature. One of the first, referred to as Ratio Metric, allows for the monitoring of possible distortions in the signal correlation. The effectiveness of the Ratio Test has been widely discussed and demonstrated, while in this paper we analyze its performance, proposing a mathematical model that is used to assess the false alarm and detection probabilities.

Infrared-to-visible upconversion enhanced photothermal catalytic degradation of toluene over Yb3+, Er3+: CeO2/attapulgite nanocomposite: Effect of rare earth doping

Jie Huang,Xuhua Ye,Wenjun Li,Anqi Shi,Xini Chu,Ziwen Cao,Chao Yao,Xiazhang Li 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.116 No.-

Developing low cost and efficient strategy to eliminate volatile organic compounds (VOCs) are quite urgent and challenging. Herein, CeO2 nanoparticles co-doped with Yb3+ and Er3+ were immobilized on attapulgite clay (ATP) for photothermal catalytic oxidation of toluene. The CeO2:Yb3+, Er3+/ATP exhibited outstanding catalytic activity with low T90 of 295 °C (temperature at 90% degradation), satisfactory stability and highly water resistance. The enhanced photothermal catalytic performance can be attributed to the optimal introduction of Yb3+ and Er3+, which promoted the up-conversion of near-infrared light (NIR) to visible light increasing the light utilization. The defects caused by Yb3+/Er3+ doping facilitated the adsorption of O2, while the active oxygen species generated from the defects and the photoinduced reactive species not only favored the oxidation of toluene in photothermal catalytic process, but also accelerated the reoxidation of reduced catalyst. Notably ATP support provided large specific surface area and abundant adsorption sites for toluene molecules to promote the deep oxidation and hindered the deactivation of catalysts caused by the accumulation of intermediates. In-situ DRIFTS test revealed that the alkoxide and benzoate appeared as the main intermediates, which can be deeply oxidized under light irradiation. Current work provides a new alternative for photothermal catalytic degradation of VOCs.

Stressing State Analysis of Reinforcement Concrete Beams Strengthened with Carbon Fiber Reinforced Plastic

Jie Huang,Jun Shi,Hengheng Xiao,Jiyang Shen,Baisong Yang 한국콘크리트학회 2020 International Journal of Concrete Structures and M Vol.14 No.5

This paper investigated the working behavior characteristics of six reinforcement concrete (RC) beams subjected to bending based on the numerical shape function (NSF) method and structural stressing state theory. Firstly, the structural stressing state mode is expressed based on the generalized strain energy density (GSED) derived from the measured strain data. Then, one of the Carbon Fiber Reinforced Plastic (CFRP)-strengthened RC beams is taken as an example and the leap characteristics of RC beam’s stressing state are detected by applying the Mann–Kendall (M–K) criterion, updating the existing definition of the structural failure load. Accordingly, the stressing state modes and strain fields of the CFRP-strengthened RC beam are proposed to reveal their leap characteristics. Furthermore, through comparing the working performance of six RC beams, the effects of different strengths and different reinforcement ratios on CFRP strengthening performance are investigated. Finally, the NSF method is applied to reasonably interpolate the limited strain data for further revealing the stressing state characteristics of the RC beams. The research results explore a new analysis method to conduct an accurate estimation of the structural failure load and provide a reference for the future design of CFRP-strengthened RC beams.
