Abstract: A control circuit for a flashing lamp provides power for the flashing lamp. The control circuit includes a control module, a strobe module, and a booster module. The control module includes an oscillator and first and second NOR gates. A square wave from the oscillator of the control module controls the first and second NOR gates to output a first control signal and a second control signal of opposite potential to the strobe module. The strobe module controls the booster module to apply boosting to the flashing lamp, reducing the number of components necessary in a control circuit for a flashing lamp.

Abstract: There is disclosed a tin-containing metal oxide nanoparticle, which has an index of dispersion degree less than 7 and a narrow particle size distribution which is defined as steepness ratio less than 3. There is disclosed dispersion, paint, shielding film and their glass products which comprise the said nanoparticles. Besides, there are also disclosed processes of making the tin-containing metal oxide nanoparticle and their dispersion. The tin-containing metal oxide nanoparticles and their dispersion disclosed herein may be applied on the window glass of houses, buildings, vehicles, ships, etc. There is provided an excellent function of infrared blocking with highly transparent, and to achieve sunlight controlling and thermal radiation controlling.

Abstract: Computer-implemented systems and methods for determining promotion prices for a plurality of items. A system and method can be configured to receive electronic data about items for a promotion event and to receive electronic data about vehicles for a promotion event. An optimizer, which is implemented on a data processor, includes or has access to an optimization formulation for determining optimal promotion prices for the items and for determining assignments of the vehicles to the items for promoting the items during the promotion event.

Abstract: Computer-implemented systems and methods for regular pricing optimization. A system can include decomposing a pricing situation into sub-problems. A non-linear optimization problem is solved to determine continuous optimal prices. A mixed integer linear programming problem is solved to snap prices to grid points.

Abstract: Described are techniques for initializing a cache in connection with storing a received data set. A previously stored data set that is similar to the received data set is identified. A cache is initialized in accordance with the previously stored data set. Processing is performed using the cache to store the received data set.

Abstract: A novel process for the preparation of amorphous cefuroxime axetil particles and the amorphous cefuroxime axetil particles therefrom are disclosed in the invention. Specifically, the invention is implemented by means of antisolvent recrystallization to prepare the cefuroxime axetil in an amorphous form; particularly, the amorphous ultrafine or even nanosized cefuroxime axetil with a controllable particle size and a narrow particle size distribution. The cefuroxime axetil according to the invention can used to enhance bioavailability, since it is in an amorphous form and has a controllable particle size and a narrow particle size distribution.
