  • SYSTEMS AND METHODS FOR GRAPH PROTOTYPICAL NETWORKS FOR FEW-SHOT LEARNING ON ATTRIBUTED NETWORKS
    Publication number: 20230117980
    Abstract: A system employs Graph Prototypical Networks (GPN) for few-shot node classification on attributed networks, and a meta-learning framework trains the system by constructing a pool of semi-supervised node classification tasks to mimic the real test environment. The system is able to perform meta-learning on an attributed network and derive a highly generalizable model for handling the target classification task. The meta-learning framework addresses extraction of meta-knowledge from an attributed network for few-shot node classification, and identification of the informativeness of each labeled instance for building a robust and effective model.

  • Polymer composites with highly tunable thermal and mechanical properties and methods of manufacture
    Patent number: 11597861
    Abstract: A method of forming an polymer composites is disclosed herein that includes infiltrating CNT sponges with a polymer or metal to form a composite. The method uses a relatively easy, scalable, and low-cost synthesis process that makes the composites attractive as TIM. CNTs in the sponge structure are covalently bonded, resulting in a low Young's modulus while at the same time maintaining a good thermal conductivity. This strategy makes it possible to obtain both high deformability and high thermal conductivity, which are difficult to have simultaneously due to their adverse correlation.

  • An Ultra-Wide Bandwidth Ultra-Isolation DC-100 Gigahertz Front-End Module with Integrated Duplexer, Low Noise Amplifier, and Power Amplifier for Wireless Communication Applications
    Publication number: 20230036705
    Abstract: Architectures of millimeter wave fully-integrated frequency-division duplex (FDD) transmitting-receiving (T/R) front-end (FE) modules include a duplexer (DUX), power amplifier (PA), and low noise amplifier (LNA) on a single semiconductor substrate to facilitate the development of system on a chip (SoC) for millimeter wave 5G wireless and next-generation communications applications. The entire balanced DUX module implements TX signals in differential mode, and RX signals in single-ended mode. LNA input is located at the center of a symmetrical plane of the entire FE module, resulting in an inherent ultra-high isolation between the differential PA output ports and the LNA input port across a ultra-wide bandwidth. The DUX can stand alone as a single unit in a system and is used together with external PA and LNA provided in the system, or it can include its own internal PA and LNA to form a DUX FE module.
