Publication number: 20240135675Abstract: Detecting fine-grained similarity in image includes determining a core area of a search image by generating an image salient map from a plurality of layers of the search image and determining a connected area based on the image salient map. Feature descriptors are generated from the core area of the search image. A plurality of capsule vectors are generated from different ones of a plurality of keypoints of the feature descriptors. Capsule vectors of the search image are compared with capsule vectors of each image of the dataset to generate a top-K matrix. Similarity scores for the top-K matrix are calculated. One or more image of the dataset having fine-grained similarity with the search image are selected based a bundled similarity score for each image of the dataset. The bundled similarity score is a summation of the similarity scores of the image.Type: ApplicationFiled: October 23, 2022Publication date: April 25, 2024Inventors: Fei Wang, Xue Ping Liu, Dan Zhang, Yun Jing Zhao, Kun Yan Yin, Zhi Xing Peng, Jian Long Sun

Publication number: 20240119563Abstract: One or more systems, devices, computer program products and/or computer-implemented methods of use provided herein relate to detecting a closed ring in a three-dimensional (3D) point cloud via cycle basis. A system can comprise a memory configured to store computer executable components; and a processor configured to execute the computer executable components stored in the memory, wherein the computer executable components can comprise a filtering component that can filter a first undirected graph of a three-dimensional (3D) point cloud, by eliminating one or more edges of the first undirected graph that are longer than an adaptive threshold, wherein filtering the first undirected graph can produce a second undirected graph; and a detection component that can detect a minimum cycle basis of the second undirected graph to determine a cycle path that can traverse an irregular annular shape that is represented by the 3D point cloud.Type: ApplicationFiled: October 5, 2022Publication date: April 11, 2024Inventors: Xue Ping Liu, Fei Wang, Dan Zhang, Kun Yan Yin, Yun Jing Zhao, Jian Long Sun, Zhi Xing Peng

Patent number: 11262349Abstract: A multiplexed method of monitoring immune-cell responses to different ligands using a micropillar/microwell plate platform is disclosed. The method may include dispensing immune cells onto at least one micropillar chip and inserting the at least one micropillar into at least one microwell on a microwell chip, in which the at least one microwell contains at least one test compound. The method may also include immobilizing antibodies onto at least one micropillar on a micropillar chip and inserting the at least one micropillar into at least one microwell on a microwell chip, in which the at least one microwell contains a test compound. The method may also include treating the micropillar chip with at least one reactive polymer.Type: GrantFiled: October 11, 2018Date of Patent: March 1, 2022Assignee: Cleveland State UniversityInventors: Moo-Yeal Lee, Xue-Long Sun

Patent number: 7713544Abstract: A biocompatible biological component is provided comprising a membrane-mimetic surface film covering a substrate. Suitable substrates include hydrated substrates, e.g. hydrogels which may contain drugs for delivery to a patient through the membrane-mimetic film, or may be made up of cells, such as islet cells, for transplantation. The surface may present exposed bioactive molecules or moieties for binding to target molecules in vivo, for modulating host response when implanted into a patient (e.g. the surface may be antithrombogenic or antiinflammatory) and the surface may have pores of selected sizes to facilitate transport of substances therethrough. An optional hydrophilic cushion or spacer between the substrate and the membrane-mimetic surface allows transmembrane proteins to extend from the surface through the hydrophilic cushion, mimicking the structure of naturally-occurring cells.Type: GrantFiled: July 30, 2001Date of Patent: May 11, 2010Assignee: Emory UniversityInventors: Elliot L. Chaikof, June Feng, Janine M. Orban, Hongbo Liu, Xue Long Sun, Keith M. Faucher

Publication number: 20050180945Abstract: Polymeric molecules including glycopolymers useful for biomolecular recognition processes are provided comprising anchoring groups by which they can be immobilized onto surfaces. These molecules are easily synthesized. They are broadly described as molecules comprising a polymer backbone with pendent multivalent groups attached to the polymer backbone and an anchoring group attached to the polymer backbone for covalently or noncovalently attaching the molecule to a surface or another molecule. Such polymeric molecules can be attached to other molecules or surfaces to provide a wide range of bioactive materials. In addition, this invention provides sulfated glycopolymers which are useful for reducing blood coagulation, stimulating growth factors to bind to their receptors, stimulating cell proliferation and preventing degradation of soluble growth factors under conditions of low pH, heat, and proteolytic enzymes.Type: ApplicationFiled: May 21, 2003Publication date: August 18, 2005Inventors: Elliot Chaikof, Xue-Long Sun
