Patent number: 11923074Abstract: Embodiments of the present disclosure provide a method for identifying those entities within a network that have the most influence on other entities within the network. A multi-relational network comprising links among a plurality of physicians is generated based on peer network data, wherein each link indicates a first physician that influences a second physician, and a weight of the influence. A decision by a treating physician of the plurality of physicians is decomposed, using a deep learning engine, into a magnitude of peer influence and a magnitude of control factor influence based on the multi-relational network and a plurality of control factors respectively. The magnitude of peer influence among one or more physicians in the multi-relational network is distributed among physicians in the multi-relational network based on the links each physician maintains with other physicians.Type: GrantFiled: February 12, 2021Date of Patent: March 5, 2024Assignee: IQVIA Inc.Inventors: Ruoxin Li, Yong Cai, John H. Eichert, Jr., Emily Zhao, Yilian Yuan, Yanping Liu, Steve Eichert, D. Bruce West, William McClellan

Publication number: 20230197255Abstract: Methods and systems to identify collaborative communities of individuals from graphs of multiple types of relationships amongst the individuals, including to mine data related to multiple types of relationships amongst individuals, construct graphs to represent the respective types of relationships amongst individuals, and perform a multiplex graph convolutional network (MGCN) artificial intelligence machine learning (AIML) analysis across the multiple graphs to identify the collaborative communities. A mathematical representation of the graphs may be learned/tuned to optimize clustering of the individuals. Multiple parameters (inter-graph weights, consensus regularization function) may be jointly tuned based on a joint optimization function. The collaborative communities may be displayed such that relative positions of the individuals represent measures of influence exerted by the respective individuals within the respective collaborative communities.Type: ApplicationFiled: December 21, 2021Publication date: June 22, 2023Inventors: Yong CAI, Yanping LIU, Ruoxin LI, Emily ZHAO, Yilian YUAN, William MCCLELLAN

Patent number: 10184053Abstract: The present invention relates to an UV coating special for PET window film and its preparation method. A pigmented UV-curable window-film coating comprising the following components in parts by mass: UV monomer: 3-40, modified acrylate: 10-50, photoinitiator: 1-10, leveling agent: 0.4-2, pigment: 3-20, coupling agent: 0.5-1.5 and dispersant: 0.4-0.8. The pigmented window film according to the present invention has the functions of being difficult to fade, UV resistance and excellent outdoor weather-resistance as well as the functions of surface-scratch resistance. The color or hue of the pigment itself can remain unchanged for several or even a dozen years. Thus, a PET window film produced from a pigment with good weather resistance can guarantee that it will keep its original color for several to a dozen years and its performance will not be influenced by outdoor environmental factors.Type: GrantFiled: May 12, 2015Date of Patent: January 22, 2019Assignee: ZHEJIANG NAMEI MATERIAL TECHNOLOGY CO., LTD.Inventors: Yao Tian, Lei Zhao, Ruoxin Li, Tao Zhang, Jun Chen
