Study of Coffee Grounds Oil Action in PVC Matrix Exposed to Gamma Radiation: Comparison of Systems in Film and Specimen Forms

, 2017
The poly (vinyl chloride), PVC, undergoes changes in its physicochemical properties when it is exposed to gamma radiation. Thus, the radiolytic stabilization of PVC is one way for obtain a material with radiation resistance.

Open‐Source Data‐Driven Prediction of Environmental, Social, and Governance (ESG) Ratings Using Deep Learning Techniques

Intelligent Systems in Accounting, Finance and Management, Volume 32, Issue 1, March 2025.
ABSTRACT The evaluation of ESG ratings by ESG rating agencies is time‐consuming and requires the participation of numerous human specialists. In this paper, we propose a method for creating proxies of ESG scores by collecting corporate ESG news and publicly available ESG‐related data using data crawling techniques and deep learning‐based classification

Highly Sensitive Dispersion Characterization of mm‐Length Silicon Nitride Waveguides and Their Couplers Around the Zero‐Dispersion Wavelength

Advanced Optical Materials, Volume 13, Issue 5, February 13, 2025.
Quantifying the dispersion of on‐chip photonic components is quintessential but remains challenging, especially if the dispersion is weak. Here, a new dispersion measurement technique based on time‐of‐flight and spatial light modulator technology is presented and applied to silicon nitride waveguides and couplers.

An AI based cross‐language aspect‐level sentiment analysis model using English corpus

Engineering Reports, Volume 6, Issue 12, December 2024.
First, a multi‐channel XLNet (Multi‐XLNet) model is used to extract contextual information from the text. Then, in the RCNN module, the contextual features are output by the forward and reverse series GRU (BiGRU) to extract deeper emotional features. Finally, the multi‐head attention mechanism obtains text attention emotion representation.
