A single double-strand break (DSB) induced by HO endonuclease triggers both repair by homologous recombination and activation of the Mec1-dependent DNA damage checkpoint in budding yeast. Here we report that DNA damage checkpoint activation by a DSB requires the cyclin-dependent kinase CDK1 (Cdc28) in budding yeast. CDK1 is also required for DSB-induced(More)
Detecting hedges and their scope in natural language text is very important for information inference. In this paper, we present a system based on a cascade method for the CoNLL-2010 shared task. The system composes of two components: one for detecting hedges and another one for detecting their scope. For detecting hedges, we build a cascade subsystem.(More)
In vivo protein-protein interactions are frequently studied by means of yeast two-hybrid analysis. However, interactions detected in yeast might differ considerably in the plant system. Based on GAL4 DNA-binding (BD) and activation domains (AD) we established an Arabidopsis protoplast two-hybrid (P2H) system. The use of Gateway-compatible vectors enables(More)
Repairing a double-strand break by homologous recombination requires binding of the strand exchange protein Rad51p to ssDNA, followed by synapsis with a homologous donor. Here we used chromatin immunoprecipitation to monitor the in vivo association of Saccharomyces cerevisiae Rad51p with both the cleaved MATa locus and the HML alpha donor. Localization of(More)
Transparent, conductive, and ultrathin graphene films, as an alternative to the ubiquitously employed metal oxides window electrodes for solid-state dye-sensitized solar cells, are demonstrated. These graphene films are fabricated from exfoliated graphite oxide, followed by thermal reduction. The obtained films exhibit a high conductivity of 550 S/cm and a(More)
As benchmark programs for microprocessor architectures, network-on-chip (NoC) traffic patterns are essential tools for NoC performance assessments and architecture explorations. The fidelity of NoC traffic patterns has profound influence on NoC studies. For the first time, this paper presents a realistic traffic benchmark suite, called MCSL, and the(More)
An intercomparison of the algorithms used to retrieve aerosol extinction and backscatter starting from Raman lidar signals has been performed by 11 groups of lidar scientists involved in the European Aerosol Research Lidar Network (EARLINET). This intercomparison is part of an extended quality assurance program performed on aerosol lidars in the EARLINET.(More)
World Wide Web, the biggest distributed system ever built, experiences tremendous growth and change in Web sites, users, and technology. A realistic and accurate characterization of Web workload is the first, fundamental step in areas such as performance analysis and prediction, capacity planning, and admission control. Compared to the previous work, in(More)
