Publication number: 20220253729Abstract: Systems and methods are described for a scalable approach to build a knowledge database of clinical trial data by extracting, aligning, and synthesizing information from a variety of sources including clinical trial registries, abstracts of papers, and full-text medical journal articles, as well as external gazetteers, dictionaries, and lexicons. For examples, a system may implement a flexible and repeatable workflow that extracts both structured and semi-structured elements from unstructured data such as journal articles using a ‘back off strategy’ in which specialized rules are used to extract structured, clinical trial design parameters as well as information retrieval techniques that exploit regularities in language used in the medical literature to discover semi-structured trial outcomes.Type: ApplicationFiled: February 1, 2022Publication date: August 11, 2022Applicant: Otsuka Pharmaceutical Development & Commercialization, Inc.Inventors: Akshay Vashist, Chumki Basu, Todd Huster, Pingji Lin, Dennis Mok, John R.

Patent number: 10371862Abstract: A method of receiving a substorm activity data log from one or more remote sensors, where substorm activity is due to solar activity. The method also includes receiving a harmonic distortion data stream from one or more remote observatories monitoring disturbances on a power grid, where the distortion is due to geomagnetically induced currents. The method also includes applying a mathematical model to the harmonic distortion data stream to create a derived harmonic distortion data log, and comparing phase-to-phase similarity of the three phases from the derived harmonic distortion data log. The method also includes predicting future adverse events due to geomagnetically-induced currents on the power grid based at least in part on the comparison and the substorm activity data log, and creating a warning based on the prediction.Type: GrantFiled: February 15, 2017Date of Patent: August 6, 2019Assignees: INTERNATIONAL BUSINESS MACHINES CORPORATION, HYDRO-QUÉBECInventors: Chumki Basu, Luc Cauchon, Sébastien Guillon, Innocent Kamwa, Manikandan Padmanaban

Patent number: 10261118Abstract: A subset of mobile devices is selected from a set of mobile devices located in a local area. From a mobile device in the subset, a magnetic measurement value obtained by performing a magnetic measurement is received. The magnetic measurement value comprises a change in a magnetic property of an immediate surrounding ambient environment of the mobile device. When the magnetic measurement corresponds to a deviation in a network condition in a portion of a network, the portion being located in the local area, a conclusion is output that the deviation is caused by an electromagnetic disturbance (EMD), where an effect of the EMD causes the magnetic measurement value. A notification including an indication of the EMD and an identification of the local area is generated.Type: GrantFiled: February 13, 2018Date of Patent: April 16, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Chumki Basu, Younghun Kim, Lloyd A.

Patent number: 10215814Abstract: Systems and methods for cognitive alarm management in a power grid are described. In one embodiment, sensor measurements are transformed to determine the state of a power grid. Given current state information relating to the power grid, various analyses of the alarms may be conducted to produce various rankings of the alarms (e.g., by severity, graph analyses, etc.). In an embodiment, using power flow analysis, an optimal ranking is identified from the rankings in which a causal alarm is prioritized for resolution. Given the resolution of the causal alarm, remaining alarms (either all or a sub-set) may be resolved without further action. Thus, an embodiment provides an appropriate ranking of alarm conditions in a power grid such that the optimal resolution of alarms may be achieved. Other variants and embodiments are broadly contemplated herein.Type: GrantFiled: August 30, 2013Date of Patent: February 26, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Chumki Basu, Kaushik Das, Jagabondhu Hazra, Devasenapathi P.
