Bin Lu,Changyu Liu,Cong Li 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.1

Informatization has always been one core competency for effective daily management. Although there are various types of management information systems available, few of them could take into account ever changing management requirements of higher vocational colleges. In this paper, we develop a J2EE based management information system for higher vocational colleges. Firstly, we perform an overview of the entire background and situation of the management informatization for higher vocational colleges. Secondly, according to requirement analysis and use case analysis, we divide the system, which requires three roles, i.e., college administrator, enterprise and graduate, into four functional modules, i.e., user login module, college administrator module, graduate module and enterprise module. Thirdly, for architecture design, we adopt a J2EE four-tier architecture, which are user presentation tier, control treatment tier, business logic tier and data persistence tier. Then, we introduce five entities, which are user information table, enterprise information table, graduate information table, recruitment information table and dynamic news table, for the database design. Furthermore, we also illustrate how we implement the final system.

A Parameter Selection Model for Avascular Tumor Growth

Changyu Liu,Bin Lu,Cong Li 보안공학연구지원센터 2014 International Journal of Control and Automation Vol.7 No.12

Based on a set of reaction-diffusion equations of oxygen, glucose and growth inhibitory factor which were built to describe the tumor growth environment, a cell cycle control factor was proposed for the simulation of the avascular tumor growth. In order to fix the model parameters, a two-level heuristic searching was given for the parameter selection. Finally, a total finite element energy equation was present to combine the chemical simulation and the physical simulation for the avascular tumor growth. Experimental results showed that the presented approach outperformed the baseline approach in the simulation of the mouse mammary tumor cells EMT6/Ro.

Changyu Liu,Bin Lu,Cong Li 보안공학연구지원센터 2014 International Journal of Smart Home Vol.8 No.6

As one kind of high quantity standardized commodities, the fruit juice product is an essential part to our daily life and overall economy. Therefore, it is necessary and important to design an efficient juicing and filling production line. According to deficiencies of traditional design methods, we propose a new design method by introducing virtual design technologies to develop a hybrid simulation system for juicing and filling production line, based on modeling software SolidWorks, virtual reality software EON Studio and application development software C++ Builder. We also describe our design method from aspects of process design and layout design, scene modeling, model import and route configuration, and interactive simulation control. Besides, we compare our design method with one traditional design method. Results show that our method can not only shorten effectively the design period but also improve greatly the design quality of the juicing and filling production line.

Bin Sun,Yu-Xiang Zheng,Cong-Hui Xu,Liang-Yao Chen,Peng Zhou,Yue-Rui Chen,Yu-Fei Kong 한국물리학회 2006 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.49 No.5I

In our work, silicon and silica composite .lms were prepared by using a magnetron sputtering method, and the samples were annealed in the temperature range between 200 ±C and 600 ±C. After annealing, the samples were investigated by spectroscopic ellipsometry (SE), and the SE spectra were measured in the range of 1.5 eV ≫ 4.5 eV with a dual-rotating-element ellipsometer. In order to investigate the microstructure information of the .lm by .tting the SE spectra using the eective- medium approximation (EMA), we modeled the whole .lm by using a multilayer optical model including a surface oxide layer, a composite layer, and substrate layer. We used dierent mixtures to describe the composite layer, and .nally we found that a mixture of amorphous silicon (a-Si), polycrystalline silicon (p-Si), and silicon dioxide had the best .t to the SE spectra. Whereafter, we studied the dependences of the surface roughness, the layer structure, and the composition on the dierent annealing temperatures and found that with increasing annealing temperature, the surface oxide layer grew in thickness, the silicon dioxide maintained its volume fraction, and a-Si transferred to p-Si.

Cap ‘n’ collar C (CncC), a transcription factor, plays a vital role in the development of insect resistance by regulating the expression of multiple detoxifying genes. Clarifying the molecular characteristics of CncC and its pathway regulating insecticide resistance will aid the development of integrated pest control strategies. Here we cloned and identified the molecular feature of CncC genes from the brown planthopper (BPH), Nilaparvata lugens (Stål), (Hemiptera Delphacidae). The full-length open reading frame of NlCncC was 3015 nucleotides with 1005 amino acids. The deduced amino acid sequence has a high similarity with other insect homologs and contains the characteristic Cnc/bZip domain architecture. Functional studies showed that silencing NlCncC by RNA interference (RNAi) could downregulate the transcript expression of NlCYP6ER1, NlCYP6CW1, and NlCYP6AY1, which increase the susceptibility to imidacloprid in N. lugens. The identification of molecular characteristics of NlCncC and func tional studies in this paper will contribute to designing effective control strategies for N. lugens.

Verification of multilevel octree grid algorithm of SN transport calculation with the Balakovo-3 VVER-1000 neutron dosimetry benchmark

Liu Cong,Zhang Bin,Wei Junxia,Tan Shuang 한국원자력학회 2023 Nuclear Engineering and Technology Vol.55 No.2

Neutron transport calculations are extremely challenging due to the high computational cost of large and complex problems. A multilevel octree grid algorithm (MLTG) of discrete ordinates method was developed to improve the modeling accuracy and simulation efficiency on 3-D Cartesian grids. The Balakovo-3 VVER-1000 neutron dosimetry benchmark is calculated to verify and validate this numerical technique. A simplified S2 synthetic acceleration is used in the MLTG calculation method to improve the convergence of the source iterations. For the triangularly arranged fuel pins, we adopt a source projection algorithm to generate pin-by-pin source distributions of hexagonal assemblies. MLTG provides accurate geometric modeling and flexible fixed source description at a lower cost than traditional Cartesian grids. The total number of meshes is reduced to 1.9 million from the initial 9.5 million for the Balakovo-3 model. The numerical comparisons show that the MLTG results are in satisfactory agreement with the conventional SN method and experimental data, within the root-mean-square errors of about 4% and 10%, respectively. Compared to uniform fine meshing, approximately 70% of the computational cost can be saved using the MLTG algorithm for the Balakovo-3 computational model.

Jiao-Na Wang,Bin-Bin Jia,Cong-Ju Li 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2015 NANO Vol.10 No.2

Hexavalent chromium (Cr (VI)) is a highly toxic pollutant which is harmful to marine organisms as well as humanity. Removing Cr (VI) from water is a hot-spot in environmental remediation. In this work, a novel kind of composite nanofibers membrane (thermal plastic elastomer ester (TPEE)@AlOOH) was first proposed by a simple method, based on a hybrid strategy composed of electrospinning and hydrothermal method. The obtained nanofibrous membrane was turned out to be a petaloid structure, which can enlarge the specific surface area of electrospun fibers. Furthermore, the Cr (VI) removal experiments suggested that the obtained nanofibrous membrane showed a high and fast efficiency, a stable recyclable property for the Cr (VI) removal. Therefore, such a novel nanofibrous membrane can be potentially widely used in Cr (VI) removal.

Murine Model Study of a New Receptor-Targeted Tracer for Sentinel Lymph Node in Breast Cancer

Chonglin Tian,Xiao Sun,Bin-Bin Cong,Pengfei Qiu,Yongsheng Wang 한국유방암학회 2019 Journal of breast cancer Vol.22 No.2

Purpose: Sentinel lymph node biopsy (SLNB), a critical staging and treatment step, has replaced axillary lymph node (LN) dissection as the standard staging procedure for early stage breast cancer patients with clinically negative axillary LNs. Hence, using a murine sentinel lymph node (SLN) model, we investigated the localization effect of the new receptor-targeted tracer, indocyanine green (ICG)-rituximab, on breast cancer SLNB. Methods: After establishing the murine SLN model, different doses of ICG-rituximab were subcutaneously injected into the hind insteps of BALB/c mice to determine the optimal dose and imaging time using continuous (> 3 hours) MDM-I fluorescence vasculature imaging. To explore the capacity of ICG-rituximab for sustained SLN localization with the optimal dose, MDM-I imaging was monitored at 6, 12, and 24 hours. Results: The popliteal LN was defined as the SLN for hindlimb lymphatic drainage, the iliac LN as the secondary, and the para-aortic or renal LN as the tertiary LNs. The SLN initial imaging and optimal imaging times were shortened with increased ICG-rituximab doses, and the imaging rates of the secondary and tertiary LNs increased accordingly. The optimal ICG dose was 0.12 μg, and its optimal imaging time was 34 minutes. After 24 hours, the SLN imaging rate remained 100%, while those of the secondary and the tertiary LNs increased from 0% (6 hours) and 0% (6 hours) to 10% (12 hours) and 10% (12 hours) to 20% (24 hours) and 10% (24 hours), respectively. Conclusion: ICG-rituximab localized to the SLN without imaging from the secondary or tertiary LNs within 6 hours. The optimal ICG dose was 0.12 μg, and the optimal interval for SLN detection was 34 minutes to 6 hours post-injection. This novel receptor-targeted tracer is of great value to clinical research and application.

Deng-Lu Hou,Rui-Bin Zhao,Yan-Yan Wei,Cong-Mian Zhen,Cheng-Fu Pan,Gui-De Tang 한국물리학회 2010 Current Applied Physics Vol.10 No.1

Zn1-xNixO (x = 0.02, 0.03, 0.04, 0.05, 0.07) films were prepared using magnetron sputtering. X-ray diffraction indicates that all samples have a wurtzite structure with c-axis orientation. X-ray photoelectron spectroscopy results reveal that the Ni ion is in a +2 charge state in these films. Magnetization measurements indicate that all samples have room temperature ferromagnetism. In order to elucidate the origin of the ferromagnetism, Zn0.97Ni0.03O films were grown under different atmospheric ratios of argon to oxygen. The results show that as the fraction of oxygen in the atmosphere decreases, both the saturation magnetization and the number of oxygen vacancies increase, confirming that the ferromagnetism is correlated with the oxygen vacancy level.
