摘要:
A hyperpolarization and multiple irradiation probe head, suitable for use in connection with magnetic resonance techniques (DNP-NMR, photo-DNP-NMR, ENDOR-EPR, MRI, DNP-MRI), comprising a RF transducer for generating and detecting a RF signal, wherein said RF transducer has a conducting element (2) allowing, together with at least one fully or partially connected grid polarizer made of conducting grid elements (1) which are reciprocally spaced so as the grid is at least partially transparent to a given microwave beam (3), controlled RF current paths and a substantially uniform RF magnetic field inside the RF transducer, wherein the grid polarizer (1) and the conducting element (2) forming the RF transducer are shaped and oriented to conform to said microwave beam phase fronts, said grid polarizer and said conducting element surrounding a sample (8), which is apt to be irradiated also by said microwaves (3); the probe head being also suited for a simultaneous irradiation of the sample with THz, FIR, IR, visible, and UV electromagnetic radiation.

摘要:
The present invention provides a dynamic pricing system that generates pricing recommendations for each product in each market. In particular, the system normalizes historic pricing and sales data, and then analyzes this historic data using parameters describing the user's business objectives to produce a pricing list to achieve these objectives. The system uses historical market data to forecast expected sales according to a market segment, product type, and a range of future dates and to determine the effects of price changes on the forecasted future sales. The system further calculates unit costs for the product. The system then estimates profits from sales at different prices by using the sales forecasts, adjusting these sales forecasts for changes in prices, and the costs determinations. The system optionally optimizes prices given current and projected inventory constraints and generates alerts notices according to pre-set conditions.
