Abstract: A method and apparatus for initializing an RRAM and an electronic device are provided. The method includes: inputting a plurality of pulses of a first voltage into an RRAM until memory cells in the RRAM transition from a high resistance state to a low resistance state; inputting a plurality of pulses of a second voltage, a third voltage . . . and an Nth voltage into the RRAM, so that resistance values of the memory cells reach a corresponding preset value, respectively. Voltage values of the first voltage to the Nth voltage gradually decrease. When a total number of input pulses of an ith voltage is greater than a second preset threshold and a resistance change rate is less than a rate threshold, a plurality of pulses of an increased ith voltage are input into the RRAM until the resistance values of the memory cells reach an ith preset value.

Abstract: The present invention relates to the technical field of microbial engineering. Specifically disclosed are a recombinant microorganism, a method for constructing same and use thereof. According to the present invention, by means of constructing a phosphate acetyltransferase-inactivated strain and applying the strain to the production of threonine, the threonine-producing ability of the strain is remarkably improved, and the strain has a remarkably increased production of threonine as compared to an unmodified strain. Combined with attenuated expression or inactivation of acetate kinase, HTH-type transcriptional regulator and the like, as well as improved activity of pyruvate carboxylase and enzymes involved in a threonine synthesis-related pathway, the production of threonine is further improved. The described modifications can be used in the fermentative production of threonine and have relatively good application value.

Abstract: Techniques are described for using data capture devices at a building to automatically generate a building floor plan and associate absolute location data with it, such as by associating separately captured GPS data or other absolute location data with the floor plan, and for presenting a model of the generated floor plan using the associated absolute location data (e.g., at a map position corresponding to the associated absolute location data). In some situations, the presenting of such a building floor plan includes showing varying levels of detail about structural aspects of the building interior and other interior aspects, such as based on the map zoom level and/or other factors. In addition, such presenting of a building floor plan may include automatically determining and using data about surroundings of the building, such as to provide information about views from the building, about directions to nearby points of interest, etc.

Abstract: A blow-molded structural panel has a stiffening rib structure in which the height and width of the rib structure varies over its length. For example, the rib structure may have three tall portions separated by two short portions, with a gradual slope in height between the various portions. The rib structure is preferably wider in the short portions than it is in the tall portions. The lower height of the rib structure in some portions enhances the stiffness of the panel, while also using less material because the plastic does not have to be drawn so deeply into the mold in the short portions.
