Zhan-Min Sun,Yan-Min Wu,Mei-Liang Zhou,Xing-Guo Xiao,Yi-Xiong Tang 한국식물생명공학회 2014 Plant biotechnology reports Vol.8 No.4

The APETALA2/ethylene-responsive elementbinding factors (AP2/ERF) play central roles in the stressresponse in plants. In this study, we identified and isolateda novel salt stress-related gene, LcERF080, that encodes anAP2/ERF protein in Lotus corniculatus cultivar Leo. LcERF080 was classified into the B-4 group of the ERFsubfamily based on multiple sequence alignment andphylogenetic characterization. Expression of LcERF080was strongly induced by salt, abscisic acid, 1-aminocyclopropane-1-carboxylic acid, methyl jasmonate, and salicylicacid stresses. Subcellular localization assay confirmedthat LcERF080 is a nuclear protein. LcERF080 overexpressionin Arabidopsis resulted in pleiotropic phenotypeswith a higher seed germination rate and transgenic plantswith enhanced tolerance to salt stress. Further, under stressconditions, the transgenic lines exhibited elevated levels ofsoluble sugars and proline as well as relative moisturecontents but a lower malondialdehyde content than incontrol plants. The expression levels of hyperosmoticsalinity response genes COR15A, RD22, and P5CS1 werefound to be elevated in the LcERF080-overexpressingArabidopsis plants compared to the wild-type plants. Theseresults reveal that LcERF080 is involved in the responsesof plants to salt stress.

Sun, Xiu-Wei,Feng, Zhan-Jun,Huang, Peng,Hao, Wang,Sui, Xing-Ling Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.4

Objective: To discuss the significance of DOG1, CD117 and PDGFRA in the diagnosis of gastrointestinal stromal tumors (GISTs), and analyze their correlations with clinicopathological features and risk ranking. Method: DOG1, CD117 and PDGFRA were detected with IHC Envision ldpe-g-nvp in 63 GISTs and 43 cases of non-GISTs, and analyzed for relations with clinicopathological factors (gender, age, location, tumor size, mitotic phase, histology) and risk degree. Results: The positive expression rate of DOG1, CD117 and PDGFRA in GISTs was 84.1% (53/63), 90.5% (57/63), 53.2% (33/63), respectively. Among the 6 CD117 negative cases, all were DOG1 positive and 5 were PDGFRA positive. Rates in patients with non-GISTs was 11.6%, 16.3%, 6.98%, respectively. Expression of DOG1 and PDGFRA demonstrated no significant variation with gender, age, position, tumor size, mitotic phase, histology, and risk rank. However, CD117 was related with position and histology (P=0.008 and P=0.045), those in the mesentery having a higher positive rate than those derived from stomach, small intestine, colon and rectum (50.0% vs 94.7%, P=0.008). Furthermore CD117 was also highly expressed in spindle and epithele types. Conclusions: DOG1 had a good sensitivity and specificity as a kind of newly discovered marker, especially for KIT negative GISTs. However, DOG1, CD117 and PDGFRA cannot be used for assessing the rish of patients.

Coupled disturbance reconstruction by sliding mode observer approach for nonlinear system

Yiyong Sun,Jinyong Yu,Zhan Li,Yu Liu 제어·로봇·시스템학회 2017 International Journal of Control, Automation, and Vol.15 No.5

This paper concentrates on the estimation of system states and the reconstruction of disturbances in aclass of nonlinear systems considering stateless situation. The disturbances are coupled with time-varying parameters. The sliding mode observer approach is utilized to solve these two issues. Firstly, a descriptor model ispresented by transforming the coupled disturbances into the decoupled form. Secondly, the sliding mode observeris designed to estimate the decoupled disturbances and system states of nonlinear systems. The coupled disturbancecan be reconstructed hereafter. The detailed methods of designing the observer, together with the sufficientcondition to guarantee the existence of the observer are also given. Finally, a simulation and a robot manipulatorexperiment are provided to examine the validity of the proposed design approach.

Zhibin Sun,Baojun Shen,Yu He,Jiecai Long,Xiaobin Zhan,Yujin Li,Xiwen Li 한국화학공학회 2022 Korean Journal of Chemical Engineering Vol.39 No.10

Extrusion pressure is crucial for the security and performance of a cylindrical extruder during the extrusion process. In this study, a validated CFD model was adopted to evaluate the relationship between the extrusion velocity, fluid viscosity, and the extrusion pressure of a cylindrical extruder while extruding highly viscous fluids. The simulated and experimental results of the extrusion pressure and velocity profiles show good agreement. This study reveals that extrusion pressure evolution can be divided into two stages during the extrusion process. At stage I, the distance between the ram and the bottom of the vessel (liquid height) is greater than the critical height and the extrusion pressure remains almost constant. At stage II, the distance is less than the critical height and the extrusion pressure increases exponentially. The results indicate that an increase in extrusion velocity and fluid viscosity leads to a linear increase in the extrusion pressure at stage I. Furthermore, by introducing a pressure number, Np, and a pressurerelated Reynolds number, Rep, a novel correlation of the extrusion pressure with the extrusion velocity, viscosity of highly viscous fluids and liquid height has been developed.

Yinggang Sun,Hongguo Zhang,Luogang Zhang,Chao Ma,Hai Huang,Dongyang Zhan,Jiaxing Qu 한국인터넷정보학회 2022 KSII Transactions on Internet and Information Syst Vol.16 No.10

Anonymization technology is an important technology for privacy protection in the process of data release. Usually, before publishing data, the data publisher needs to use anonymization technology to anonymize the original data, and then publish the anonymized data. However, for data publishers who do not have or have less anonymized technical knowledge background, how to configure appropriate parameters for data with different characteristics has become a more difficult problem. In response to this problem, this paper adds a historical configuration scheme resource pool on the basis of the traditional anonymization process, and configuration parameters can be automatically recommended through the historical configuration scheme resource pool. On this basis, a privacy model hybrid recommendation algorithm for user satisfaction is formed. The algorithm includes a forward recommendation process and a reverse recommendation process, which can respectively perform data anonymization processing for users with different anonymization technical knowledge backgrounds. The privacy model hybrid recommendation algorithm for user satisfaction described in this paper is suitable for a wider population, providing a simpler, more efficient and automated solution for data anonymization, reducing data processing time and improving the quality of anonymized data, which enhances data protection capabilities.

Determination of equivalent blasting load considering millisecond delay effect

Song, Zhan-Ping,Li, Shi-Hao,Wang, Jun-Bao,Sun, Zhi-Yuan,Liu, Jing,Chang, Yu-Zhen Techno-Press 2018 Geomechanics & engineering Vol.15 No.2

In the analysis of the effects of rock tunnel blasting vibration on adjacent existing buildings, the model of simplified equivalent load produces higher calculation result of vibration, due to the lack of consideration of the millisecond delay effect. This paper, based on the static force equivalence principle of blasting load, proposes a new determination method of equivalent load of blasting vibration. The proposed method, based on the elastic-static force equivalence principle of stress wave, equals the blasting loads of several single blastholes in the same section of millisecond blasting to the triangle blasting load curve of the exploded equivalent elastic boundary surface. According to the attenuation law of stress wave, the attenuated equivalent triangle blasting load curve of the equivalent elastic boundary is applied on the tunnel excavation contour surface, obtaining the final applied equivalent load. Taking the millisecond delay time of different sections into account, the time-history curve of equivalent load of the whole section applied on the tunnel excavation contour surface can be obtained. Based on Sailing Tunnel with small spacing on Sanmenxia-Xichuan Expressway, an analysis on the blasting vibration response of the later and early stages of the tunnel construction is carried out through numerical simulation using the proposed equivalent load model considering millisecond delay effect and the simplified equivalent triangle load curve model respectively. The analysis of the numerical results comparing with the field monitoring ones shows that the calculation results obtained from the proposed equivalent load model are closer to the measured ones and more feasible.
