We employ cut and paste contact topological techniques to classify some tight contact structures on the closed, oriented genus-2 surface times the interval. A boundary condition is specified so that the Euler class of the of the contact structure vanishes when evaluated on each boundary component. We prove that there exists a unique, non-product tight contact structure in this case. AMS Classif...

Anti-plagiarism tools are currently used in a large number of institutions to perform an initial assessment of students’ essays, enabling an automated approach to the identification of plagiarised work. This paper presents evidence that students are moving from “copy and paste” plagiarism, which can be detected by anti-plagiarism software, to more complex forms of plagiarism using a variety of ...

Stencil printing remains the technology route of choice for flip chip bumping because of its economical advantages over traditionally costly evaporation and electroplating processes. This paper provides the first research results on stencil printing of 80 μm and 60 μm pitch peripheral array configurations with Type 7 Sn63/Pb37 solder paste. In specific, the paste particle size ranges from 2 μm ...

Code clone is a code fragment that has identical or similar fragments to it in the source code. Many code clone detection techniques and tools have been proposed. However, source code derived by copy-and-paste may be disguised by obfuscation because these techniques detect code clone using only static information such as source code or binary. Therefore, we propose a new clone detection techniq...

Cut-and-Paste Text Summarization

In this paper, we evaluate the extent to which human-written book summaries can be obtained through cut-and-paste operations from the original book. We analyze the effect of the parameters involved in the decomposition algorithm, and highlight the distinctions in coverage obtained for different summary types.

In this work, the back surface field (BSF) formation of locally alloyed Al paste contacts employed in recent industrial passivated emitter and rear cell solar cell designs is discussed. A predictive model for resulting local BSF thickness and doping profile is proposed that is based on the time dependent Si distribution in the molten Al paste during the firing step. Diffusion of Si in liquid Al...

The consumption of tomatoes and tomato products has been associated with a reduced risk of prostate cancer. We observed a decrease of 10.77% in prostate-specific antigen (PSA) levels in patients with benign prostate hyperplasia who were submitted to daily ingestion of tomato paste. This was an experimental rather than a controlled study with a sample of 43 men ranging in age from 45 to 75 years...

This study was conducted to evaluate the antifungal activities of Cinnamomum zeylanicum and Origanum vulgare L. essential oil against Aspergillus flavus in culture media and tomato paste. 200 ppm of cinnamon and 500 ppm of oregano completely inhibited A. flavus growth in culture media, while in tomato paste 300 ppm of cinnamon and 200 ppm of oregano had the same effect. Test panel evaluations r...

This data article contains an atlas of paste fabrics and supplemental paste compositional data generated from Late Middle Preclassic-period ceramics at the Maya site of Holtun, Guatemala. The data include maps showing locations of archeological contexts, excavation profiles, photographs and photomicrographs of sherds and paste fabrics, and compositional data produced by Neutron Activation Analy...
