The method relates to means to increase expression level of a bHLH subgroup 1b gene expression or activity, wherein a desired phenotype such as increased heat tolerance relative to a wild type control plant following heat stress results in reduced flower abortion and increased yield. Included are plants produced by said methods. The invention also relates to nucleic acid sequences and constructs useful such methods and methods of generating and isolating plants having increased expression of a bHLH subgroup 1b expression or activity.

  • Patent number: 8119498
    Abstract: A wafer bonding process that compensates for curvatures in wafer surfaces, and a wafer stack produced by the bonding process. The process entails forming a groove in a surface of a first wafer, depositing a bonding stack on a surface of a second wafer, aligning and mating the first and second wafers so that the bonding stack on the second wafer contacts a bonding site on the first wafer, and then heating the first and second wafers to reflow the bonding stack. The groove either surrounds the bonding site or lies entirely within the bonding site, and the heating step forms a molten bonding material, causes at least a portion of the molten bonding material to flow into the groove, and forms a bonding structure that bonds the second wafer to the first wafer. Bonding stacks having different lateral surface areas can be deposited to form bonding structures of different heights to compensate for variations in the wafer gap.

  • Publication number: 20110009773
    Abstract: Implantable sensing modules and methods for monitoring various physical parameters, including physical parameters of a living body and environmental parameters to which the living body may be subjected, for example, impacts. A method for monitoring impacts to which a living body is subjected entails the use of an implantable sensing module that has a rigid housing containing at least one energy storage device and at least one electromechanical sensing element that is responsive to impacts. The module generates data corresponding to impacts to which the electromechanical sensing element is subjected, and records the data in memory. The module is preferably implanted in a living body so that the module is connected to a rigid portion of the living body, in particular, a bone or tooth.
