  • Publication number: 20260024737
    Abstract: An ion beam lens and methods for combining ion beams are disclosed. Embodiments combine hyperthermal ion beams and can include layered three-dimensional electrodes with passageways through the electrodes, each electrode having a specified DC voltage and each passageway configured for passing an ion beam to an exit, the velocity vectors of the beams being primarily oriented along the lens' central axis upon exiting the passageways. Embodiments include nested electrode plates with curved ion beam passageways. In some embodiments each electrode plate has a charge different from the electrode plates adjacent to it, and in some embodiments every other electrode plate is charged with a first DC voltage and the remaining plates are charged with a second DC voltage different from the first DC voltage.

  • Publication number: 20250171791
    Abstract: Compositions and methods for transiently expressing proteins in a plant are provided. The compositions comprise plants, seeds, plant tissues, and plant parts expressing a protein, wherein the protein is expressed transiently and the transient expression of the protein can be used as a predictive model of how said protein will be expressed in stable transgenic plants in regards to qualitative and quantitative data. The predictive model may be used but is not limited to: promoter evaluation, evaluation of expression cassette construction for best performance (e.g. addition of enhancers or gene silencing suppressors), evaluation of best ways to express heterologous genes.

  • Publication number: 20240301440
    Abstract: Provided herein are regulatory elements, such as transcriptional enhancers, introns, and terminators derived or obtained from various sources including Zea mays and plant viruses. Such regulatory elements are useful for expression cassettes for plants, including monocots (e.g., maize) and dicots (e.g., soy). Enhancers which increase gene expression of tissue specific promoters while maintaining tissue specific expression are provided.

  • Patent number: 9068191
    Abstract: This invention provides methods of transiently expressing a nucleotide sequence in one or more cells of a soybean plant, comprising: a) abrading the surface of a soybean plant and/or intact part thereof; and either (b1) immersing the abraded plant and/or abraded intact part thereof in a solution comprising Agrobacterium cells and a surfactant, wherein the Agrobacterium cells comprise the nucleotide sequence to be transiently expressed; (b2) applying a vacuum to the immersed soybean plant and/or intact part thereof of step (b1); and (b3) releasing the vacuum, thereby introducing the solution into the plant and/or intact part thereof; or (c) contacting the abraded plant and/or abraded intact part thereof with a solution comprising Agrobacterium cells and a surfactant, wherein the Agrobacterium cells comprise the nucleotide sequence to be transiently expressed, whereby the nucleotide sequence is transiently expressed in one or more cells of the plant.

  • Publication number: 20060038415
    Abstract: The present invention relates generally to a fastener module for portable computers that is disposed on the host of a portable computer to fasten the LCD with the host of the portable computer, no matter whether the LCD of the portable computer is closed directly or after rotating 180 degrees; the fastener module has a pivotable eccentric hook rod with a normal horizontal position under the effect of an elastic component when not being affected by magnetic effect, when the LCD closes on the host of the computer, both sides of the hook rod are affected by the magnetic effect of the magnetic component on the LCD; since the pivot of the hook rod is designed eccentrically, the magnetic moment generated by the magnetic effect for each side of the hook rod is different, so that the hook rod changes it position instantly from normal horizontal state to vertical state and hooks in the opening of the LCD to fasten the LCD onto the host of the portable computer.
