Patent number: 11959904Abstract: In a method for sensing translocation of a molecule through a nanopore, a molecule in a first fluidic solution in a first fluidic reservoir that is in direct fluidic connection with the nanopore is directed to a nanopore inlet and translocated through the nanopore to a nanopore outlet and through a fluidic passage that is in direct fluidic connection with the nanopore outlet, to a second fluidic solution in a second fluidic reservoir disposed in direct fluidic connection with the fluidic passage. The fluidic passage has at least one fluidic section in which a length of the fluidic section is greater than a width of the fluidic section. Translocation of the molecule through the nanopore is sensed by measuring the electrical potential local to the fluidic passage during the translocation of the molecule.Type: GrantFiled: August 31, 2020Date of Patent: April 16, 2024Assignee: President and Fellows of Harvard CollegeInventor: Ping Xie

Publication number: 20240104371Abstract: Embodiments of a generative framework comprise cooperative learning of two generative flow models, in which the two models are iteratively updated based on the jointly synthesized examples. In one or more embodiments, the first flow model is a normalizing flow that transforms an initial simple density into a target density by applying a sequence of invertible transformations, and the second flow model is a Langevin flow that runs finite steps of gradient-based MCMC toward an energy-based model. In learning iterations, synthesized examples are generated by using a normalizing flow initialization followed by a short-run Langevin flow revision toward the current energy-based model. Then, the synthesized examples may be treated as fair samples from the energy-based model and the model parameters are updated, while the normalizing flow directly learns from the synthesized examples by maximizing the tractable likelihood. Also provided are both theoretical and empirical justifications for the embodiments.Type: ApplicationFiled: September 19, 2022Publication date: March 28, 2024Applicant: Baidu USA LLCInventors: Jianwen XIE, Yaxuan ZHU, Jun LI, Ping LI

The trans fluidic access resistance, RT, is of the same order of magnitude as the nanopore fluidic resistance, RP, and both RT and RP are at least an order of magnitude greater than the cis fluidic access resistance, RC. An indication of local electrical potential is produced at a site within the nanopore sensor that is on the trans fluidic ionic solution-side of the nanopore, to sense translocation of the molecule through the nanopore.Type: GrantFiled: April 29, 2022Date of Patent: September 26, 2023Assignee: President and Fellows of Harvard CollegeInventors: Ping Xie, Charles M.

Publication number: 20230080984Abstract: A file system executing on a computing device may store a placeholder for a file on secondary storage of the computing device. The placeholder may comprise a sparse data stream containing none or some of the data of the file and information which enables the remotely stored data of the file to be retrieved from the network. As some or all of the data for the file is being stored remotely, the computing device may rely on a storage virtualization provider to create metadata for the file. Thus, the file system executing on the computing device may receive, from the storage virtualization provider, a request to store metadata associated with the file. In response to this request, the file system may store the metadata as a Binary Large Object (BLOB) in a secondary data stream of the placeholder for the file.Type: ApplicationFiled: November 21, 2022Publication date: March 16, 2023Applicant: Microsoft Technology Licensing, LLCInventors: Neal R.

Publication number: 20230066840Abstract: Using metadata for a contentless file to provide a guest context access to file content. Within a guest context, a file system is mounted from a container image which lacks a first file's content and which includes metadata defining properties of the first file and mapping data defining information for identifying a second file within another filesystem from which the first file's content is obtainable Based on the properties, a filesystem operation involving the first file is performed without switching to a host context, and a requested access to the first file's content is responded to. Responding includes, based on the mapping data, communicating a request for the host context to supply the first file's content and, after returning from a context switch, responding to the requested access by supplying content of the second file from guest memory page(s) which are mapped to host memory page(s) containing the second file's content.Type: ApplicationFiled: January 27, 2021Publication date: March 2, 2023Inventors: Ping XIE, Scott BRENDER, Shaheed Gulamabbas CHAGANI, John Andrew STARKS, Arun U.
