Surface-enhanced Raman scattering (SERS) is a powerful spectroscopy technique that can provide non-destructive and ultra-sensitive characterization down to single molecular level, comparable to single-molecule fluorescence spectroscopy. However, generally substrates based on metals such as Ag, Au and Cu, either with roughened surfaces or in the form of(More)
Fine-grained data parallelism is increasingly common in mainstream processors in the form of longer vectors and on-chip GPUs. This paper develops support for exploiting such data parallelism for a class of non-numeric, non-graphic applications, which perform computations while traversing many independent, irregular data structures. While the traversal of(More)

Sometimes, a license even carries the key that is used to unlock the protected content. Unfortunately, license protection is difficult, yet it is important for digital rights management (DRM).

BACKGROUND Phenazines are important compounds produced by pseudomonads and other bacteria. Two phz gene clusters called phzA1-G1 and phzA2-G2, respectively, were found in the genome of Pseudomonas sp. M18, an effective biocontrol agent, which is highly homologous to the opportunistic human pathogen P. aeruginosa PAO1, however little is known about the(More)
The Intel Xeon Phi offers a promising solution to coprocessing, since it is based on the popular x86 instruction set. However, to fully utilize its potential, applications must be vectorized to leverage the wide SIMD lanes, in addition to effective large-scale shared memory parallelism. Compared to the SIMT execution model on GPGPUs with CUDA or OpenCL,(More)
The pursuit of computational efficiency has led to the proliferation of throughput-oriented hardware, from GPUs to increasingly wide vector units on commodity processors and accelerators. This hardware is designed to efficiently execute data-parallel computations in a vectorized manner. However, many algorithms are more naturally expressed as(More)
In bacteria, RNA-binding proteins of the RsmA/CsrA family act as post-transcriptional regulators that modulate translation initiation at target transcripts. The Pseudomonas aeruginosa genome contains two phenazine biosynthetic (phz) gene clusters, phzA1-G1 (phz1) and phzA2-G2 (phz2), each of which is responsible for phenazine-1-carboxylic acid (PCA)(More)
The conductance of single-molecule junctions may be governed by the structure of the molecule in the gap or by the way it bonds with the leads, and the information contained in a Raman spectrum is ideal for examining both. Here we demonstrate that molecule-to-surface bonding may be characterized during electron transport by 'fishing-mode' tip-enhanced Raman(More)
Eclipta prostrata (EP) is often prescribed in combination with glucocorticoid to treat glomerular nephritis, nephrotic syndrome, and IgA nephropathy in clinical practice of Traditional Chinese Medicine. Previous studies from our laboratory revealed that coadministration of EP significantly increased the plasma concentration of prednisolone while decreased(More)
