MEDT: Using Multimodal Encoding-Decoding Network as in Transformer for Multimodal Sentiment Analysis

IEEE Access, 2022
Multimodal sentiment analysis is a challenging task in the field of natural language processing (NLP). It uses multimodal signals (natural language, facial gestures, and acoustic behavior) in videos to generate emotional understanding.

(1E,3E)-1,4-Dinitro-1,3-butadiene—Synthesis, Spectral Characteristics and Computational Study Based on MEDT, ADME and PASS Simulation

Molecules, 2023
The chemistry of conjugated nitrodienes is becoming increasingly popular. These molecules are successfully applied in cycloaddition to synthesize six-membered rings in Diels-Alder reactions. Nitrodienes can be also applied to obtain bis-compounds in [3+2]

A Mechanistic Insight into the Molecular Mechanism of the Thermal Decomposition of Nitroalkyl Phosphates: MEDT Computational Study. [PDF]

Materials (Basel)
The kinetic aspects and molecular mechanism of the thermal decomposition of nitroalkyl phosphates were evaluated on the basis of DFT quantum-chemical calculations at the ωb97xd/6-311G(d,p) (PCM) level of theory. These reactions were found to proceed via a single-step mechanism with a six-membered transition state.
