Abstract: An embodiment of a system for measuring trace gas concentration is described that comprises a laser absorption spectrometer configured to detect an absorbance measure from a trace gas, as well as a temperature value and a pressure value that correspond to an environment in a gas cell; and a computer having executable code stored thereon configured to perform a method comprising: receiving the absorbance value, the temperature value, and the pressure value; defining a fitting range associated with the trace gas; applying a curve fitting model in the fitting range to the absorbance value using the temperature value and the pressure value as model parameters; and producing a concentration measure of the trace gas.

Abstract: A system including a display output device, a computer including instructions that when executed by the computer, cause the computer to generate a virtual environment, instantiate one or more virtual devices into the virtual environment, instantiate a user representation into the virtual environment, and display the virtual environment, the one or more virtual devices, and the user representation on the display output device, an input device to receive a movement input associated with movement by the user representation in the virtual environment, and the computer further configured with instructions to move or rotate the one or more virtual devices relative to a point of reference in the virtual environment in response to the movement input, while maintaining the user representation stationary.

Abstract: Efficient sequence specific gene silencing is possible through the use of siRNA technology. By selecting particular siRNAs by rational design, one can maximize the generation of an effective gene silencing reagent, as well as methods for silencing genes. Methods, compositions, and kits generated through rational design of siRNAs are disclosed including those directed to nucleotide sequences for TTR.

Abstract: A tamper seal detection system for detecting a sealing sticker on a packaging box includes a housing at least partially bounding an inspection zone, the inspection zone being configured to receive the packaging box. A first sensor is configured to detect the presence of the first sealing sticker located on the packaging box when the packaging box is received within the inspection zone. A push guide is movable relative to the inspection floor between a first position and a spaced apart second position and can be used to push the packaging box out of the inspection zone.
