摘要： The invention provides methods and compositions for the modulation of proanthocynidin (“PA;” condensed tannin) production in plants. The methods of the invention allow creation of plants having novel phenotypes, such as alterations in levels of PA or in the types of tissues in which PAs are produced. Altered expression of PA in plants may be achieved, for instance without significantly affecting anthocyanin content or overall secondary metabolite profiles. Alternatively, expression of PA in plants may be achieved while also affecting anthocyanin content.

摘要： A brushless motor has a stator and a rotor. The stator has a stator core with a plurality of inwardly extending salient poles and windings wound about the salient poles. The rotor has a shaft, a rotor core fixed onto the shaft, and magnets inserted in the rotor core for forming magnetic poles of the rotor. Each of the salient poles has a pole shoe with a pole face that extends along a circumferential direction confronting the rotor core and being spaced from the rotor core by an air gap. In a radial cross section of the motor, each of the magnetic poles of the rotor has an effective dimension (W) which is about 0.85 times to 1.2 times of the chord length (L) of each pole face.

摘要： A method of transmitting data between a plurality of base stations and a plurality of mobile stations is provided. The method includes ranking data links between the plurality of base stations and the plurality of mobile stations according to a quality criterion, and selecting a subset of data links for transmitting the data between the plurality of base stations and the plurality of mobile stations such that a predetermined requirement is satisfied. Selecting the subset of data links may include iteratively assigning a predetermined value to power of the data link having the lowest ranking and determining if the predetermined requirement is satisfied, until the predetermined requirement is no longer satisfied. The remaining data links may then be selected for transmitting the data between the plurality of base stations and the plurality of mobile stations.
