Second-harmonic generation was studied in III-metal-polar GaN films grown on sapphire substrates by metalorganic chemical vapor deposition and formed into ridge waveguides. Broadband near-IR femtosecond pulses of an optical parametric amplifier system were injected by end-fire coupling and the nonli ...

Whatever kind of physics may be found at the LHC, strongly-interacting particles will be involved and therefore quantum chromodynamics will play a crucial role. For processes at high energy scales, perturbation theory remains the most powerful approach. These lectures will review the foundations ...

Scientists frequently have multiple types of experiments and data sets on which they can test the validity of their parametrized models and locate plausible regions for the model parameters. By examining multiple data sets, these scientists can obtain inferences for their problems which typically ar ...

Recent developments in programmable, highly parallel Graphics Processing Units (GPUs) have enabled high performance implementations of machine learning algorithms. We describe a solver for Support Vector Machine training, using Platt's Sequential Minimal Optimization algorithm and an adaptive first ...

Three ways to support extensibility have been discussed for XLIFF 2.0: (1) allow custom namespaces in prescribed elements (similar to XLIFF 1.2); (2) provide XML elements and attributes to prescribe extensibility (no custom namespaces); (2) allow both options, but be very picky about which are valid ...

Multilingual content on the web is no longer a luxury, but instead a requirement for most organizations. Although getting web content translated, prepared, and onto the web is hardly turn-key, a best practice is emerging. Many organizations have turned to Web Content Management Systems (CMS) to solv ...

We present DeepWalk, a novel approach for learning latent representations of vertices in a network. These latent representations encode social relations in a continuous vector space, which is easily exploited by statistical models. DeepWalk generalizes recent advancements in language modeling and un ...

Graph clustering and graph outlier detection have been studied extensively on plain graphs, with various applications. Recently, algorithms have been extended to graphs with attributes as often observed in the real-world. However, all of these techniques fail to incorporate the user preference into ...

Given a bipartite graph of users and the products that they review, or followers and followees, how can we detect fake reviews or follows? Existing fraud detection methods (spectral, etc.) try to identify dense subgraphs of nodes that are sparsely connected to the remaining graph. Fraudsters can eva ...
