Publication number: 20260024737Abstract: 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.Type: ApplicationFiled: September 30, 2025Publication date: January 22, 2026Inventors: Julia LASKIN, Hang Hu, Pei Su

Publication number: 20250171791Abstract: 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.Type: ApplicationFiled: November 25, 2024Publication date: May 29, 2025Applicant: SYNGENTA CROP PROTECTION AGInventors: Kasimalai Azhakanandam, Jonathan Cohn, Zhongying Chen, Qiudeng Que, Pei Su

Publication number: 20240301440Abstract: 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.Type: ApplicationFiled: December 20, 2021Publication date: September 12, 2024Applicant: SYNGENTA CROP PROTECTION AGInventors: Kasimalai Azhakanandam, Jonathan Cohn, Zhongying Chen, Qiudeng Que, Pei Su

Publication number: 20060038415Abstract: 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.Type: ApplicationFiled: February 3, 2005Publication date: February 23, 2006Applicant: COMPAL ELECTRONICS, INC.Inventors: Jen-Hao Liu, Jung-Sheng Chiang, Yu-Yuan Lin, Ko-Chun Cheng, Ching Chang, Pei Su
