Patent number: 11983734Abstract: A system and method for advertising cannibalization management are provided. In example embodiments, historical data comprising advertisement revenue, advertisement parameters, and a cannibalization metric are accessed. The cannibalization metric is indicative of sales loss associated with an advertisement presentation. A value for at least one of the advertisement parameters that, when used, causes a desired advertisement revenue with respect to a bounded cannibalization metric is determined by analyzing the historical data. An advertisement is presented, in real time, on a user interface of a client device using the determined value.Type: GrantFiled: March 29, 2023Date of Patent: May 14, 2024Assignee: PayPal, Inc.Inventors: Chitta Ranjan, Huma Zaidi, Neha Singh

Publication number: 20230086363Abstract: Fluorescent bimetallic nanocomposites (M1@M2-NCs) of silver-gold (Ag@Au-NC) and silver-platinum (Ag@Pt-NC) are prepared by reducing silver nitrate (AgNO3) on gold nanoparticles (AuNPs) and platinum nanoparticles (PtNPs) using sodium borohydride (NaBH4) at alkaline pH=11, in the presence of a lysozyme that acts as a template, and in the presence of a capping and stabilizing agent. The biocompatible bimetallic nanocomposites (M1@M2-NCs) have promising multifunctional applications (cell imaging, bio-sensing, therapeutics) observed by both in vitro as well as in vivo experiments. The fluorescent bimetallic nanocomposites (M1@M2-NCs) of silver-gold (Ag@Au-NC) and silver-platinum (Ag@Pt-NC) may be useful as an alternative nanomedicine in cancer theranostics applications.Type: ApplicationFiled: March 5, 2021Publication date: March 23, 2023Inventors: Sourav DAS, Sudip MUKHERJEE, Chitta Ranjan PATRA

Patent number: 10806715Abstract: The current invention relates to development of new formulation containing gold nanoparticles (AuNPs) with bi-functional recombinant fusion proteins TRAF(C) for the delivery of anticancer drugs and nucleic acids to HER2+ cancers. Using the combinatorial approach, we designed gold nanoparticle-based targeted drug delivery system (TDDS) or (Au-TR-DX-si) by combining AuNPs with bi-functional recombinant fusion protein TRAF(C) (TR), doxorubicin (DX) and siRNA (si). The recombinant protein based gold nanoparticles formulations are stable and homogenous as revealed by several physicochemical studies. In addition, the engineered fusion protein TRAF (C) has the ability to target selectively to HER2+ receptors overexpressed in ovarian cancer cells (SK-OV-3).Type: GrantFiled: October 23, 2017Date of Patent: October 20, 2020Assignee: Council of Scientific & Industrial ResearchInventors: Rajesh Kotcherlakota, Sudip Mukherjee, Chitta Ranjan Patra, Vijaya Gopal

Patent number: 10782711Abstract: A method, an electronic device, and a computer readable medium for fuel blending are disclosed. The method includes deriving a volume of each product from at least two products that is transferred from separate source containers to fill a destination container. The method also includes transferring a portion of the derived volume of each of the products sequentially into the destination container, wherein each product is transferred one at a time. The method further includes repeating the transfer of the portion of each of the products for a plurality of cycles until the derived volume of each of the products is transferred into the destination container. Each product of at least two products is transferred individually and sequentially during each of the cycles. The portion of the derived volume is based on the plurality of cycles.Type: GrantFiled: July 20, 2018Date of Patent: September 22, 2020Assignee: Honeywell International Inc.Inventor: Chitta Ranjan Panigrahi

Patent number: 10231996Abstract: The present invention relates to highly biocompatible or nontoxic PVP (poly(n-vinyl-2-pyrrolidone) coated silver prussian blue nanoparticles (SPB-NPS: Ag3[Fe(CN)6] where PVP acts as stabilizing or capping agent. The as-synthesized nanoparticles (SPB-NPs) have been thoroughly characterized by several analytical tools. The SPB-NPs are highly stable for more than two weeks towards different physiological buffers or solutions with different pH (pH=6, ?7.4 & ?8). These nanoparticles (SPB-NPs) exhibit biocompatibility towards various normal cells (HUVEC, CHO, & ECV304) but show significant inhibition of proliferation of different cancer cells in vitro and tumor growth in C57/BL6/J mice model (aggressive murine melanoma cancer model: B16F10). Additionally, the SPB-NPs show excellent antibacterial activity towards gram-negative (E. coli) and gram-positive (B. subtilis) bacteria.Type: GrantFiled: February 22, 2016Date of Patent: March 19, 2019Assignee: COUNCIL OF SCIENTIFIC & INDUSTRIAL RESEARCHInventors: Sudip Mukherjee, Chitta Ranjan Patra
