The Grid Resource Discovery Method Based on Hierarchical Model
Yulan Yin,Huanqing Cui,Xin Chen
Information Technology Journal , 2007,
Abstract: Grid is considered as next generation network and resource discovery is a basic component of Grid resource management. This study presents a hierarchical resource discovery method to make use of attractive features of lumped and exhaustive methods. In this study, the resources in Grid are setup in a 3-layer resource organizational model including Physical Network Layer, Resource Information Layer and Index Information Layer. A resource discovery method based on the above hierarchical model is provided. The simulation result proves that the method discussed is of fine extensibility and performance. Furthermore, it can discover a required resource concurrently to improve the efficiency.

Yulan Zhang, Heather Song
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2013, DOI: 10.4236/jemaa.2013.53018
Abstract:

A miniaturized square resonator bandpass filter with circular stubs is designed, fabricated, and characterized. Analytical calculations were carried out to determine the critical filter parameters and the design was optimized using a 3D electromagnetic finite-element solver. The measured results were in good agreement with the designed results. The proposed filter exhibits significant improvement in bandwidth compared to the conventional square resonator bandpass filters.

Photonic structure in the wings of Papilio bianor ganesa
YouHua Qin,Feng Liu,HaiWei Yin,YuLan Wang,XiaoHan Liu,Li Zhao
Chinese Science Bulletin , 2007, DOI: 10.1007/s11434-007-0412-9
Abstract: We conducted structural characterizations, reflection measurements, and theoretical simulations on the iridescent green of the wings of Papilio bianor ganesa. We found that the green iridescence originated from a stack of about 9 periodic structure composed of chitin layers and air-spacer layers. This periodic structure gave rise to a high-reflection band in yellowish-green part of the visible spectrum under normal incidence. With increasing incident angle, all reflection peaks showed a blue shift in wavelength. Based on the structural characterizations, the theoretical simulations accurately predicted the shifts in spectral reflectivity which might be observed experimentally.
Resistance of SKW6 cell to apoptosis induction with anti-Fas antibody upon transduction of a reverse fragment to a cDNA encoding human 6A8 α-mannosidase

Abstract: The effect of transduction with a reverse fragment to a cDNA encoding human 6A8 α-mannosidase on apoptosis induction of human B cell line SKW6 by anti-Fas antibody was tested. Apoptosis-inducer of anti-Fas monoclonal antibody was used to induce apoptosis in SKW6 cells. Giemsa’s staining, Annexin-V-FLUOS staining and DNA ladder test were used to determine the events of apoptosis. Indirect immunofluorescent staining with anti-Fas antibody was performed to detect the surface Fas expression. In a time-course test of 12, 24 and 36 h for apoptosis induction by anti-Fas antibody, DNA ladder was observed in the wild-type SKW6 cells in a time-dependent fashion. Mock transduction had no effect on DNA ladder production. However, no DNA ladder was detected in the rAAV-antisense 6A8 cDNA-transduced SKW6. Results from Annexin-V-FLUOS staining on anti-Fas antibody-treated cells revealed that the staining-positive rate in the rAAV-antisense 6A8 cDNA-transduced SKW6 cells was decreased in comparison to that in the wild-type and the mock-transduced cells. Giemsa’s staining observation showed that the number of dying (with apoptotic bodies) and dead cells was reduced in the rAAV-antisense 6A8 cDNA-transduced SKW6 cells in comparison with that in the wild-type and the mock-transduced cells upon anti-Fas antibody induction. The transduction did not affect the expression of Fas molecular on cell surface. 100% cells in all the groups showed Fas expression. The SKW6 cells became resistant to apoptosis induction by anti-Fas antibody upon transduction with a reverse fragment to a cDNA encoding human 6A8 α-mannosidase. The transduction did not affect the expression of Fas molecule on cells.

Actions of Right-Angled Coxeter Groups on the Croke Kleiner Spaces
Yulan Qing
Mathematics , 2014,
Abstract: It is an open question whether right-angled Coxeter groups have unique group-equivariant visual boundaries. Croke and Kleiner present a right-angled Artin group with more than one visual boundary. In this paper we present a right-angled Coxeter group with non-unique equivariant visual boundary. The main theorem is that if right-angled Coxeter groups act geometrically on a Croke-Kleiner spaces, then the local angles in those spaces all have to be right angles. We present a speci?c right-angled Coxeter group with non-unique equivariant visual boundary. However, we conjecture that the right an- gled Coxeter groups that can act geometrically on a given CAT(0) space are far from unique.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.2782.2787
Abstract: The effects of spermine on the development of small intestine and growth performance of newly weaned pigs were investigated. Thirty pigs were used and the treatment of spermine was through oral administration for the 1st 3 days after weaning with the dose of 0, 300, 600, 900 or 1200 μmol per pig daily. The administration of spermine improved Average Daily Feed Intake (ADFI) and Average Daily Gain (ADG) in the periods 0-14 (p<0.05) but had no significant effects on the ratio of Feed to Gain (F/G) and protein/DNA contents of the duodenal or ileal mucosa. The protein/DNA content of the jejunum was significantly increased at the doses of 300 and 600 μmol day-1 spermine but was declined at the higher doses. The villus height in the duodenum (p<0.01) and ileum (p<0.05) increased with an increase in spermine doses. The crypt depth was reduced by spermine in the jejunum and the ratio of villus height/crypt depth was increased by spermine in the duodenum, jejunum and ileum (p<0.05). Additionally, the treatment of spermine at tested doses showed no effect on D-xylose absorption by the small intestine. These results indicate that oral administration of spermine for 3 days after weaning increased ADG and ADFI, enhanced the development of the small intestinal mucosa and improved intestinal morphology.
Bayesian models and meta analysis for multiple tissue gene expression data following corticosteroid administration
Yulan Liang, Arpad Kelemen
BMC Bioinformatics , 2008, DOI: 10.1186/1471-2105-9-354
Abstract: Bayesian categorical model for estimating the proportion of the 'call' are used for pre-screening genes. Hierarchical Bayesian Mixture Model is further developed for the identifications of differentially expressed genes across time and dynamic clusters. Deviance information criterion is applied to determine the number of components for model comparisons and selections. Bayesian mixture model produces the gene-specific posterior probability of differential/non-differential expression and the 95% credible interval, which is the basis for our further Bayesian meta-inference. Meta-analysis is performed in order to identify commonly expressed genes from multiple tissues that may serve as ideal targets for novel treatment strategies and to integrate the results across separate studies. We have found the common expressed genes in the three tissues. However, the up/down/no regulations of these common genes are different at different time points. Moreover, the most differentially expressed genes were found in the liver, then in kidney, and then in muscle.Despite rapid advancements in statistical methods for gene expression microarray analysis, much more work is needed for multiple source heterogeneous genomic data, such as multiple organisms/tissues, multiple platforms, multiple species and even more from transcriptome, genome, to proteome in order to develop valid and dependable methods that are mainly applicable to microarray data. The congruency of these different data sources needs a unified framework for combining the multiple sources and testing associations between them, thus obtaining a robust and integrated view. In the meantime, we may find a surprising discrepancy present elsewhere between gene expressions given multiple source of genomic data sets.Meta-analysis is a set of statistical procedures designed to integrate experimental and correlational results across independent studies that address a related set of research questions [1-4].

Statistical advances and challenges for analyzing correlated high dimensional SNP data in genomic study for complex diseases
Yulan Liang,Arpad Kelemen
Statistics Surveys , 2008,
Abstract: Recent advances of information technology in biomedical sciences and other applied areas have created numerous large diverse data sets with a high dimensional feature space, which provide us a tremendous amount of information and new opportunities for improving the quality of human life. Meanwhile, great challenges are also created driven by the continuous arrival of new data that requires researchers to convert these raw data into scientific knowledge in order to benefit from it. Association studies of complex diseases using SNP data have become more and more popular in biomedical research in recent years. In this paper, we present a review of recent statistical advances and challenges for analyzing correlated high dimensional SNP data in genomic association studies for complex diseases. The review includes both general feature reduction approaches for high dimensional correlated data and more specific approaches for SNPs data, which include unsupervised haplotype mapping, tag SNP selection, and supervised SNPs selection using statistical testing/scoring, statistical modeling and machine learning methods with an emphasis on how to identify interacting loci.
