Integrable Hierarchy of Higher Nonlinear Schrödinger Type Equations

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2006
Addition of higher nonlinear terms to the well known integrable nonlinear Schrödinger (NLS) equations, keeping the same linear dispersion (LD) usually makes the system nonintegrable. We present a systematic method through a novel Eckhaus-Kundu hierarchy,

NL versus NP

open access: yes, 2020
P versus NP is considered as one of the most important open problems in computer science. This consists in knowing the answer of the following question: Is P equal to NP? It was essentially mentioned in 1955 from a letter written by John Nash to the United States National Security Agency.

Enhanced antioxidant performance of phlorotannin compounds from brown seaweed Sargassum tenerrimum via nanoliposomal encapsulation

open access: yesFood Chemistry Advances
Seaweeds contain natural antioxidants, known as phlorotannins; however, their direct use in food is limited. Nanoliposomes (NLs) have small, uniform particle sizes (20 nm), a high entrapment efficiency (90 %), and good stability.

LEO-PNT Feasibility Aspects: Satellite Navigation Payload Size, Weight, and Power Analysis

open access: yesIEEE Access
Low Earth Orbit (LEO) satellites are expected to improve the robustness and reliability of critical Positioning, Navigation, and Timing (PNT) services by increasing both the efficiency and diversity of Global Navigation Satellite Systems (GNSS). However,
