Database Interrelation Miner

The Interrelation Miner Methodology is a technology for multivariate statistical data analysis and outcome prediction (data mining) of either complex and/or multidimensional data sets, or of very small datasets based on statistical fuzzy set theory. This tool can be applied to any complicated data set with many samples or variables (e.g., micro array data), and provides results for small or incomplete data tables by using very simple decision rules with nonlinear data models. The Interrelation Miner has analyzed gas chromatography/mass spectrometry data and has provided up to 20% better prediction performance than compared approaches. Other possible applications include: microarrays, protein arrays, environmental data sets, food quality control, and quality control in general.

Lactic-Acid-Producing Bacterial Strain

This technology has solved the problem of adding beneficial lactic-acid-producing bacteria (LAB) to both wet and dry foods that undergo processing with heat and pressure. The bacterial strain is able to withstand harsh manufacturing regimes including high- compression tableting, coating, highshear blending, and excessive heating. Previously, most LAB could be distributed only in refrigerated wet foods (such as yogurt) and less than 1% of it survived to reach the digestive tract. The new LAB strain delivers 200 times the beneficial bacteria to the digestive tract over current strains, and has been used in products for the treatment of the symptoms of lactose-intolerance, irritable bowel syndrome, Crohn’s disease, colitis, arthritis, psoriasis, and a number of other digestive problems. It also has been shown to strengthen the immune system, improve absorption of vitamins and minerals, aid in digestion generally, and displace harmful bacteria in the digestive tract.

Design Software Bridges Optical/Mechanical Gap for Life Sciences

The inherently interdisciplinary nature of developing instrumentation for life sciences requires a high level of collaboration between scientists and engineers across the fields of analytical or clinical chemistry, optics, mechanics, material science, and microbiology. Moreover, product development teams are competing for first-tomarket benefits that are driven by intellectual property lifetimes and insuring an installed base quickly to realize recurring consumable sales. Concurrently, product designers need to comply with current Good Manufacturing Practices (cGMP). System-level modeling enables adherence to the methodical design process without the cost and time associated with iterative hardware prototyping and laboratory and clinical testing.
