Oligonucleotide microarrays, also called "DNA chips," are currently made by a light-directed chemistry that requires a large number of photolithographic masks for each chip. Here we describe a maskless array synthesizer (MAS) that replaces the chrome masks with virtual masks generated on a computer, which are relayed to a digital micromirror array. A 1:1(More)
Mycobacteriophages are viruses that infect mycobacterial hosts such as Mycobacterium smegmatis and Mycobacterium tuberculosis. All mycobacteriophages characterized to date are dsDNA tailed phages, and have either siphoviral or myoviral morphotypes. However, their genetic diversity is considerable, and although sixty-two genomes have been sequenced and(More)
MOTIVATION Microarrays are a fast and cost-effective method of performing thousands of DNA hybridization experiments simultaneously. DNA probes are typically used to measure the expression level of specific genes. Because probes greatly vary in the quality of their hybridizations, choosing good probes is a difficult task. If one could accurately choose(More)
Agricultural animal research has been immensely successful over the past century in developing technology and methodologies that have dramatically enhanced production efficiency of the beef, dairy, swine, poultry, sheep, and aquaculture industries. In the past two decades, molecular biology has changed the face of agricultural animal research, primarily in(More)
INTRODUCTION Agricultural animal research has been immensely successful over the past century in developing technology and methodologies that have dramatically enhanced production efficiency of the beef, dairy, swine, poultry, sheep, and aquaculture industries. Most of this research effort has been conducted within the broad disciplines of genetics,(More)

(2007) " Image and video noise-a comparison of noise in images and video with regards to detection and removal ". Abstract Most cameras detect colour by using sensors that separate red, green and blue wavelengths of light which is similar to the human eye.(More)
Accurate partition coefficients K = Corg/Caq in chloroform-ammonia can be obtained by measuring the absorbance of the aqueous layer, replenishing with fresh aqueous solvent, and remeasuring the absorption after reequilibration. Provided the solute has a reasonably strong UV absorption, only 0.1-5 mg of material is required. Neither the amount, the(More)
