Abstract: Methods and devices are provided for optically interrogating subsurface tissues of a body. Optical interrogation includes illumination of a target tissue through an external body surface and detection of light emitted in response to the illumination. Parameters of such optical interrogation are controlled according to operational modes that are selected to maximize detector sensitivity to a target property of the target subsurface tissues. Operational modes are selected based on detected properties of the target tissue and of intervening tissues (e.g., thickness of intervening tissues between the target tissue and an external body surface) between the target tissue and an interrogating optical device. Operational modes can be determined based on simulated optical interrogation of subsurface tissue across a range of optical detector configurations and tissue conditions. Operational modes can include calibration curves specifying optical interrogation parameters based on intervening tissue properties.

Abstract: A method of preparing a fluoroelastomer capable of being vulcanized by using peroxide, the method comprising: in the presence of an initiator and a chain transfer agent, conducting emulsion polymerization reaction on comonomers to obtain a fluoroelastomer.

The fluoroelastomer obtained via the preparation method greatly improves the performance after being vulcanized; in addition, due to the low cost and extensive sources of alkyl iodide, the preparation method also simplifies the manufacturing process, reduces cost, and has wide application prospects.

Abstract: Techniques and systems are disclosed for improving the computation and solution of bilevel MIP problems. Various single-level reformulation techniques can be used to transform a bilevel MIP problem into soluble form. Decomposition techniques can be applied to the single-level reformulations to iteratively converge on an optimal or near-optimal solution. Some techniques described herein are operative within software applications for solving mathematical problems or MIP problems, and some are operable within an application programming interface or MIP solution service that other software components can access. In some cases, the techniques may be operative within domain-specific modeling software that solves, models, plans, or suggests actions in particular scenarios, for example power grid interdiction analysis and defense tools.

Abstract: A request control device, request control method, and a multiprocessor cooperation architecture. The request control device is connected to a request storage module and includes a comparing means and an identifier means. The comparing means is configured to determine if an incoming first queue unit corresponds to the same message with a queue unit that has existed in the request storage module. The identifier setting means is configured to set a save identifier of the queue unit that has existed in the request storage module to indicate not to save a state associated with the message if the first queue unit corresponds to the same message with the queue unit that has existed in the request storage module. According to the technical solution of the invention, the access to the memory caused by saving/loading the states is reduced and thereby increases the processing speed of the processor.
