Abstract:
The present invention is based on the discovery of a two organism model system that can be used to identify virulence factors. The system is also useful in the process of drug delivery. More specifically, we have established valid fungal infection in caenorhabditis elegans with an invading pathogen, the yeast Saccharomyces cerevisiae. Because both species are genetic model organisms, the assay can be used to identify host and virulence factors involved in such interactions.

Abstract:
Methods and systems for observing/analyzing, interactive behavior are presented. In one instance, the method for observing/analyzing interactive behavior includes interacting, using a robot, with a subject and obtaining data from interaction between the subject and the robot, the data from the data acquisition components, the data being used for diagnosis and/or charting progress. In one instance, the robot includes data acquisition components, interaction inducing components (such as, but not limited to, movable eyelids, movable appendages, sound generating components), a control component operatively connected to the interaction inducing components and a processing component operatively connected to the control component and the data acquisition components, the processing component being configured to obtain data from the data acquisition components, the data being used for diagnosis and/or charting progress. In one instance, the robot is integrated with a computer-aided system for diagnosis, monitoring, and therapy.
Abstract:
The present invention is a low-cost, easily deployed, degradable taggant that can be dispersed over a wide area to serve as a witness to activity in the area and for queuing of other sensors. The taggant enables nearly real-time change detection within the treated area using one or more simple optical sensing techniques.

Abstract:
A flexible wall bioreactor is described that uses a small droplet size mist unit, a lower rate ambient air flow rate, and a flexible wall culture chamber to provide an environment that allows for the growth of dense root matrix, shoot cultures, and 2 and 3 dimensional animal tissues.
Abstract:
The invention relates to a method of signal analysis that determines the location of a transmitter and to devices that implement the method. The method includes receiving by at least three receivers, from a transmitter, a first continuous-time signal having a first channel. The first channel includes a first plurality of signal carriers having known relative initial phases and having known frequencies which are periodically spaced and which are orthogonal to one another within a first frequency range. The signal analysis method also includes determining the phase shifts of the carriers of the first channel resulting from the distance the carriers traveled in reaching the first receiver. Analysis of the phase shifts yields time difference of arrival information amongst the receivers, which is further processed to determine the location of the transmitter.
Abstract:
An alloy solute sensor probe, measurement system and measurement method are disclosed for directly measuring solute concentration profiles in conductive material components at elevated processing temperatures. The disclosed device and method permit direct, real-time non-destructive measurement of solute concentration profiles in treated surfaces in alloy components. In disclosed embodiments, a novel concentric carbon sensor and rod-shaped carbon sensor are disclosed which employ AC frequencies for probing the subsurface region of alloy samples to determine carbon concentration profiles at steel surfaces from measurements of alloy resistivity profiles. Results of carbon profile measurements obtained with the disclosed device and method compare favorably with conventional destructive analytical measurements made on post-processed samples. The sensor probe and method may be utilized to determine solute concentration profiles with a variety of solute materials and alloy compositions and may be advantageously employed in alloy surface processing, carburization heat treatments, induction heating and fatigue fracture applications.
