    Conditional Diagnosability of Burnt Pancake Networks Under the PMC Model (2016)
    Oxford University Press
    Details
    Publication Date: 2016-01-08
    Description: The $n$ -dimensional burnt pancake network, denoted by $BP_n$ , originates from the Burnt pancake problem which relates to the construction of networks of parallel processors. In the wake of rapid development of multiprocessor systems, processor fault diagnosis plays an even more important role in measuring the reliability of a multiprocessor system, and the diagnosabilities of many well-known multiprocessor systems have been investigated. The conditional diagnosability has been widely accepted as a new measure of diagnosability by assuming that any faulty set cannot contain all the neighbors of any node in a multiprocessor system. In this paper, we explore combinatorial properties of burnt pancake networks, and investigate the structural vulnerability as well as extra connectivities. Furthermore, we show that the classic diagnosability and the conditional diagnosability of $BP_n$ ( $n\geq 4$ ) under the Preparata, Metze and Chien model are $n$ and $8n-13$ , respectively.

    Transgenic poplar overexpressing the endogenous transcription factor ERF76 gene improves salinity tolerance (2016)
    Oxford University Press
    Details
    Publication Date: 2016-08-03
    Description: The ethylene response factor (ERF) family is one of the largest plant-specific transcription factor families, playing an important role in plant development and response to stresses. The ERF76 gene is a member of the poplar ERF transcription factor gene family. First, we validated that the ERF76 gene expressed in leaf and root tissues is responsive to salinity stress. We then successfully cloned the ERF76 cDNA fragment containing an open reading frame from di-haploid Populus simonii   x   Populus nigra and proved that ERF76 protein is targeted to the nucleus. Finally, we transferred the gene into the same poplar clone by the Agrobacterium -mediated leaf disc method. Using both RNA-Seq and reverse transcription-quantitative polymerase chain reaction, we validated that expression level of ERF76 is significantly higher in transgenic plants than that in the nontransgenic control. Using RNA-Seq data, we have identified 375 genes that are differentially expressed between the transgenic plants and the control under salt treatment. Among the differentially expressed genes, 16 are transcription factor genes and 45 are stress-related genes, both of which are upregulated significantly in transgenic plants, compared with the control. Under salt stress, the transgenic plants showed significant increases in plant height, root length, fresh weight, and abscisic acid (ABA) and gibberellin (GA) concentration compared with the control, suggesting that overexpression of ERF76 in transgenic poplar upregulated the expression of stress-related genes and increased the ability of ABA and GA biosynthesis, which resulted in stronger tolerance to salt stress.

    Thermal analysis of PCM-filled glass windows in hot summer and cold winter area (2016)
    Oxford University Press
    Details
    Publication Date: 2016-05-27
    Description: Phase change material (PCM)-filled glass window was suitable for absorbing or releasing more heat than conventional glass window. Comparisons of thermal performance between PCM-filled glass windows and insulated glass windows (double glass windows filled with dry air and surrounded by sealing strips) were presented in this paper. A 3D unsteady model was built in FLUENT to obtain the internal and external surface temperature fluctuations of these windows in 48 h. Compared with insulated glass windows, thermal performance (especially the thermal regulation effect) of double glass windows filled with Na 2 SO 4 ·10H 2 O was quite satisfactory in sunny days of summer, while double glass windows filled with CaCl 2 ·6H 2 O had a better thermal performance in overcast and rainy days of summer. Because the phase change temperature of these PCM is higher than the ambient temperature in winter, the thermal regulation effects of them were not as good as expected.

    A 3-D enlarged cell technique (ECT) for elastic wave modelling of a curved free surface (2016)
    Oxford University Press
    Details
    Publication Date: 2016-07-29
    Description: The conventional finite-difference time-domain (FDTD) method for elastic waves suffers from the staircasing error when applied to model a curved free surface because of its structured grid. In this work, an improved, stable and accurate 3-D FDTD method for elastic wave modelling on a curved free surface is developed based on the finite volume method and enlarged cell technique (ECT). To achieve a sufficiently accurate implementation, a finite volume scheme is applied to the curved free surface to remove the staircasing error; in the mean time, to achieve the same stability as the FDTD method without reducing the time step increment, the ECT is introduced to preserve the solution stability by enlarging small irregular cells into adjacent cells under the condition of conservation of force. This method is verified by several 3-D numerical examples. Results show that the method is stable at the Courant stability limit for a regular FDTD grid, and has much higher accuracy than the conventional FDTD method.

    Network-based analysis of genotype-phenotype correlations between different inheritance modes (2014)
    Oxford University Press
    Details
    Publication Date: 2014-11-07
    Description: Motivation: Recent studies on human disease have revealed that aberrant interaction between proteins probably underlies a substantial number of human genetic diseases. This suggests a need to investigate disease inheritance mode using interaction, and based on which to refresh our conceptual understanding of a series of properties regarding inheritance mode of human disease. Results: We observed a strong correlation between the number of protein interactions and the likelihood of a gene causing any dominant diseases or multiple dominant diseases, whereas no correlation was observed between protein interaction and the likelihood of a gene causing recessive diseases. We found that dominant diseases are more likely to be associated with disruption of important interactions. These suggest inheritance mode should be understood using protein interaction. We therefore reviewed the previous studies and refined an interaction model of inheritance mode, and then confirmed that this model is largely reasonable using new evidences. With these findings, we found that the inheritance mode of human genetic diseases can be predicted using protein interaction. By integrating the systems biology perspectives with the classical disease genetics paradigm, our study provides some new insights into genotype–phenotype correlations.

    Enrichment of Cdk1-cyclins at DNA double-strand breaks stimulates Fun30 phosphorylation and DNA end resection (2016)
    Oxford University Press
    Details
    Publication Date: 2016-04-08
    Description: DNA double-strand breaks (DSBs) are one of the most cytotoxic types of DNA lesion challenging genome integrity. The activity of cyclin-dependent kinase Cdk1 is essential for DSB repair by homologous recombination and for DNA damage signaling. Here we identify the Fun30 chromatin remodeler as a new target of Cdk1. Fun30 is phosphorylated by Cdk1 on Serine 28 to stimulate its functions in DNA damage response including resection of DSB ends. Importantly, Cdk1-dependent phosphorylation of Fun30-S28 increases upon DNA damage and requires the recruitment of Fun30 to DSBs, suggesting that phosphorylation increases in situ at the DNA damage. Consistently, we find that Cdk1 and multiple cyclins become highly enriched at DSBs and that the recruitment of Cdk1 and cyclins Clb2 and Clb5 ensures optimal Fun30 phosphorylation and checkpoint activation. We propose that the enrichment of Cdk1-cyclin complexes at DSBs serves as a mechanism for enhanced targeting and modulating of the activity of DNA damage response proteins.

    More evidence for the red-shift dependence of colour from the Joint Light-curve Analysis supernova sample using red-shift tomography (2016)
    Oxford University Press
    Details
    Publication Date: 2016-06-17
    Description: In this work, by applying the red-shift tomography method to the Joint Light-curve Analysis (JLA) supernova sample, we explore the possible red-shift dependence of the stretch luminosity α and the colour luminosity β. The basic idea is to divide the JLA sample into different red-shift bins, assuming that α and β are piecewise constants. Then, by constraining the CDM model, we check the consistency of the cosmology-fitting results given by the supernova sample of each red-shift bin. We also adopt the same technique to explore the possible evolution of β in various subsamples of JLA. Using the full JLA data, we find that α is always consistent with a constant value. In contrast, at high red shift, β has a significant trend of decreasing, at ~3.5 confidence level (CL). Moreover, we find that the low- z subsample favours a constant β; in contrast, the Sloan Digital Sky Survey and Supernova Legacy Survey subsamples favour a decreasing β at 2 and 3.3 CL, respectively. Besides, by using a binned parametrization of β, we study the impact of the evolution of β on parameter estimation. We find that compared with a constant β, a varying β yields a larger best-fitting value of fractional matter density m 0 , which slightly deviates from the best-fitting result given by other cosmological observations. However, for both the varying β and the constant β cases, the 1 regions of m 0 are still consistent with the result given by other observations.
