GUI Reliability Assessment based on Bayesian Network and Structural Profile
Zhi-Fang Yang,Zhong-Xing Yu,Bei-Bei Yin,Cheng-Gang Bai 보안공학연구지원센터(IJSIP) 2015 International Journal of Signal Processing, Image Vol.8 No.1
Graphical User Interfaces (GUI) is becoming increasingly important in the software field as it builds a friendly way between users and software through continuous interactions. A well-developed GUI is therefore an important factor of software quality. In particular, the reliability of GUIs is still on the way of development. Existing software reliability assessment techniques attempt to statistically describe the software testing process and predict the reliability of the system. However, those techniques are not suitable for GUI as quality of GUI is challenged by immense number of event interactions and complex structural profile etc. Furthermore, GUI has a wealth of information about GUI architecture, components, windows and their interactions with each other, which can be adopted to guide the testing process and establish confidence assessment of GUI. In this paper, a Bayesian network model of GUI reliability is introduced to discuss the reliability model topology and its issues encountered in the modeling process. A case is also presented to verify the validity of the model during the GUI reliability assessment process.

In this study, two soybean genotypes, i.e., aluminum-tolerant Baxi 10 (BX10) and aluminumsensitive Bendi 2 (BD2), were used as plant materials and acidic red soil was used as growth medium. The soil layers from the inside to the outside of the root are: rhizospheric soil after washing (WRH), rhizospheric soil after brushing (BRH) and rhizospheric soil at two sides (SRH), respectively. The rhizosphere bacterial communities were analyzed by high-throughput sequencing of V4 hypervariable regions of 16S rRNA gene amplicons via Illumina MiSeq. The results of alpha diversity analysis showed that the BRH and SRH of BX10 were significantly lower in community richness than that of BD2, while the WRH exhibited no significant difference between BX10 and BD2. Among the three sampling compartments of the same soybean genotype, WRH had the lowest community richness and diversity while showing the highest coverage. Beta diversity analysis results displayed no significant difference for any compartment between the two genotypes, or among the three different sampling compartments for any same soybean genotype. However, the relative abundance of major bacterial taxa, specifically nitrogen-fixing and/or aluminum-tolerant bacteria, was significantly different in the compartments of the BRH and/or SRH at phylum and genus levels, indicating genotype-dependent variations in rhizosphere bacterial communities. Strikingly, as compared with BRH and SRH, the WRH within the same genotype (BX10 or BD2) always had an enrichment effect on rhizosphere bacteria associated with nitrogen fixation

Zhi-Gang Tai,Le Cai,Ya-Bin Yang,Chuan-Shui Liu,Jian-Jun Xia,Zhong-Tao Ding 대한화학회 2010 Bulletin of the Korean Chemical Society Vol.31 No.10
Three new oleanane-type triterpene saponins (1, 2 and 3) were isolated from aerial parts of Gladiolus gandavensis,along with two known compounds (4 and 5). Their structures were elucidated as 29-O-(β-D-glucopyranosyl)-2β,3β-dihydroxyolean-12-en-28-oicacid(1), 3-O-(β-D-xylopyranosyl)-29-O-(β-D-glucopyranosyl)-12-en-28-oic acid (2),and 2β,3β,29-trihydroxyolean-12-en-28-oic acid 28-O-[β-D-glucopyranosyl(1→2)-(α-L-rhamnopyranosyl(1→6))-β-D-glucopyranosyl] ester (3), by spectroscopic methods, and by comparison with known analogues. These oleanane-type triterpene saponins glycosidated at C-29 were not obtained frequently.
Analytical and Design Method for the Global Stability of Modular Steel Buildings
Zhi-Hua Chen,Xu Zhong,Yang Liu,Jiadi Liu 한국강구조학회 2021 International Journal of Steel Structures Vol.21 No.5
Modular steel buildings (MSBs) are an innovative form of prefabricated buildings with many advantages related to the factory-manufactured construction process. However, technical issues in the global stability design remain ambiguous and induce either unsuitable or uneconomical results without understanding the eff ect of intermodule connections appropriately. In this study, one practical theoretical equation to determine the buckling length factor for the sway-permitted MSB was derived from a sub-assembly considering pinned or rigid inter-module connections. A large number of fi nite element models were then used to numerically validate the eff ectiveness of the theoretical equation and explore the main infl uencing factors including both intermodule connections and height-to-width ratios. Results indicated that the intermodule connections should be carefully considered when the fl oor beams are obviously larger than ceiling beams, and theoretical results can be accurate enough when the height-to-width ratios remain within 3.0. Moreover, the second-order analysis method for MSB was also performed by using nonlinear buckling analyses and then compared with the buckling length method to verify the previous fi ndings. Finally, the criterion in selecting the proper stability design procedure for MSB was discussed in depth.
Dynamic modeling and control of industrial crude terephthalic acid hydropurification process
Zhi Li,Weimin Zhong,Yang Liu,Na Luo,Feng Qian 한국화학공학회 2015 Korean Journal of Chemical Engineering Vol.32 No.4
Purified terephthalic acid (PTA) is critical to the development of the polyester industry. PTA productionconsists of p-xylene oxidation reaction and crude terephthalic acid (CTA) hydropurification. The hydropurificationprocess is necessary to eliminate 4-carboxybenzaldehyde (4-CBA), which is a harmful byproduct of the oxidation reactionprocess. Based on the dynamic model of the hydropurification process, two control systems are studied usingAspen Dynamics. The first system is the ratio control system, in which the mass flows of CTA and deionized water arecontrolled. The second system is the multivariable predictive control-proportional-integral-derivative cascade controlstrategy, in which the concentrations of 4-CBA and carbon monoxide are chosen as control variables and the reactiontemperature and hydrogen flow are selected as manipulated variables. A detailed dynamic behavior is investigatedthrough simulation. Results show that the developed control strategies exhibit good control performances, thereby providingtheoretical guidance for advanced control of industry-scale PTA production.
CLV1 Interacts with UFO in Modulation of Gynoecium Development in Arabidopsis thaliana
Zhi-Peng Cheng,Zhong-Nan Yang,Sen Zhang 한국식물학회 2013 Journal of Plant Biology Vol.56 No.1
The gynoecium is the female reproductive structurein flowering plants. It has been known that the CLAVATA1(CLV1) gene regulates the floral meristem maintenance andfloral organ number in Arabidopsis thaliana. However,whether CLV1 plays roles in gynoecium development remainsuncharacterized. In this study, we showed that CLV1genetically interacts with Unusual Floral Organs (UFO) toregulate the development of Arabidopsis gynoecium. Throughforward genetic screen, we identified a clv1 allele, clv1-9,showing abnormal gynoecium development. Some epidermalcells on the growing inner surfaces of the clv1-9 gynoeciumfailed to fuse after contacting with each other, suggesting thatCLV1 is essential for proper postgenital fusion. Furthermore,the ufo clv1-9 double mutant exhibited an expanded uppergynoecium, narrowed lower part of the ovary, alteredvascular patterning and abaxial outward proliferation of thetransmitting tract tissues. The transcription level of the ETTgene, which is required for gynoecium structure and patternformation, was down-regulated in the ufo clv1-9 doublemutant genoecia. Taken together, our results indicate thatCLV1 functions together with UFO to regulate gynoeciumdevelopment likely through modulating the expression ofETT.
Ghost Cell Odontogenic Carcinoma Arising from Calcifying Cystic Odontogenic Tumor: A Case Report
Zhi-Yu Zhu,Yu Chen,Zhi-Gang Chu,Wei-Ping Zhang,Di Lv,Ning Geng,Ming-Zhong Yang 대한병리학회 2012 Journal of Pathology and Translational Medicine Vol.46 No.5
Ghost cell odontogenic carcinoma (GCOC) is an exceptionally rare and malignant odontogenic tumor with aggressive growth characteristics. We describe a case of GCOC which was considerably derived from a previously resected calcifying cystic odontogenic tumor (CCOT). Cellular atypia, mitotic activity, Ki-67 labeling index and matrix metalloprotease-9 positive expression rate were all increased in the currently resected specimen compared to the initial one. This is a rare case of malignant transformation of CCOT to GCOC with respect to its histopathological and immunohistochemical findings.

Semi-dwarfism is an agronomically important trait in breeding for resistance to damage by wind and rain (lodging resistance)and for stable high yields. Dwarf Polish wheat (Triticum polonicum L., 2n = 4x = 28, AABB AS304) is a potential donor of dwarfing and other traits for common wheat improvement. A genetic analysis using an F2 population derived from a cross of AS304 and tall cultivar AS302 and derived F2:3 lines indicated that AS304 carries a recessive dwarfing gene, temporarily designated Rht-dp. Molecular markers and bulked segregant analysis were used to characterize and map the gene. Eight polymorphic SSR markers (Xwmc511, Xgwm495, Xgwm 113, Xgwm192, Xgpw7026, Xgpw3017, Xgpw1108 and Xgpw7521) on chromosome arm 4BS and two AFLP markers (M8/E5 and M4/E3) were mapped relative to the dwarfing locus. The closest linked markers, Xgpw3017 and M8/E5 at 0.5 and 3.5 cM, respectively, from Rht-dp will enable its marker assisted transfer to wheat breeding populations. Allelic tests indicated that Rht-dp was allelic to Rht-B1b; hence it may be an alternative allele at the Rht-B1 locus.

1-Deoxynojirimycin (DNJ) as a kind of alkaloid has been confirmed that could modulate glycometabolism andhas toxicity for the eri-silkworm in our previous research. On the contrary, what is the potentially defensivemechanism when the DNJ enters the eri-silkworm. Based on comparative transcriptome sequencing, we foundthat ATP-binding cassette (ABC) transporter genes could be induced significantly by DNJ. In this study, a total of16 putative ABC transporter genes were identified, which can be classified into seven subfamilies, namely oneABCA, four ABCBs, three ABCCs, two ABCDs, one ABCE, three ABCFs, and two ABCGs. Phylogenetic analysisrevealed that ScABCs had strong conservation with Bombyx mori. Reverse transcription quantitative PCR (RTqPCR)suggested that 6 ABC transporters had a strong positive correlation between RT-qPCR and transcriptomedata. Additionally, S. c. ricini ABC transporter C-subfamily 4 (ScABCC4), S. c. ricini ABC transporter G-subfamily4 (ScABCG4), S. c. ricini ABC transporter A-subfamily 3 (ScABCA3) and S. c. ricini ABC transporter C-subfamily10 (ScABCC10) showed different expression pattern in two feed dose (1% and 2% DNJ) and three time points(6h, 12 h, 48 h). This study provides the first study on identification, characterization and expression patterns ofABC transporter genes in S. c. ricini response to DNJ, and lays a foundation for further understanding of theirphysiological roles response to the alkaloid.
