MOTIVATION Array-based analysis of chromatin immunoprecipitation (ChIP-chip) data is a powerful technique for identifying DNA target regions of individual transcription factors. The identification of these target regions from comprehensive promoter array ChIP-chip data is challenging. Here, three approaches for the identification of transcription factor target genes from promoter array ChIP-chi...

background mycobacterium tuberculosis is a vicious microbe co-existing with the infected host. this pathogen exploited opportunities to spread during periods of urbanization and social upheaval, and got retreated with improved hygiene. objectives this investigation was designed to clone and characterize m. tuberculosis mutt gene, a homologue of a dna repair protein in escherichia coli. the aim ...

A 1xN2 wavelength-selective switch is demonstrated using a high fill-factor two-axis analog micromirror array and a monolithic 2D collimator array. A 1x2 (scalable to 1x14) WSS with SO-GHz channel spacing is experimentally demonstrated. 02004 Optical Society of America OCIS rodeo: (06C.1810) Couplers, switches, and multiplexers (OM.4510) Optical communications

The chemoreceptors of Escherichia coli localize to the cell poles and form a highly ordered array in concert with the CheA kinase and the CheW coupling factor. However, a high-resolution structure of the array has been lacking, and the molecular basis of array assembly has thus remained elusive. Here, we use cryoelectron tomography of flagellated E. coli minicells to derive a 3D map of the inta...

We have developed sensitive detection of cancer biomarker vascular endothelial growth factor (VEGF) using the p-n heterojunction comprised of p-type BiOI nanoflakes (NFs) array and n-type TiO2 nanotubes (NTs) array. Due to the unique arrayed structure and the synergy effect of photoelectrochemistry in the formed p-n junction, the synthesized configuration has superior excitation efficiency and ...

We present a low-cost shaped beam synthesis method for semi-smart base station antennas. Compared with the conventional array synthesis for smart antenna applications, the proposed circular/conformal array shaped beam synthesis for semi-smart antenna has much lower system complexity and instrumentation implementation cost. This is because only few elements are involved and the circular array fa...

Human enteric viruses are recognized as the main causes of food- and waterborne diseases worldwide. Sensitive and quantitative detection of human enteric viruses is typically achieved through quantitative RT-PCR (RT-qPCR). A nanofluidic real-time PCR system was used to develop novel high-throughput methods for qualitative molecular detection (RT-qPCR array) and quantification of human pathogeni...

3D imaging based on single-photon avalanche diode (SPAD) arrays is of interest in many applications. Limited by the small array size and low fill-factor available SPAD array, it difficult for array-based lidars to achieve high-resolution high-quality images currently. Here, we propose a sub-pixel continuously scanning panoramic method. This method uses increase spatial resolution employs accumu...

We review recent progress in calculating kaon spectrum, pseudoscalar meson decay constants, B K , ε ¡ £ ¢ ε, K ¤ ππ matrix elements, kaon semileptonic form factors, and moments of kaon distribution amplitudes on the lattice. We also address the issue of how best to improve the staggered fermion formulation for the action and operators.
