Fact-based Agent modeling for Multi-Agent Reinforcement Learning [PDF]

arXiv, 2023
In multi-agent systems, agents need to interact and collaborate with other agents in environments. Agent modeling is crucial to facilitate agent interactions and make adaptive cooperation strategies. However, it is challenging for agents to model the beliefs, behaviors, and intentions of other agents in non-stationary environment where all agent ...

Production of yeast cell wall polysaccharides‐β‐glucan and chitin by using food waste substrates: Biosynthesis, production, extraction, and purification methods

Comprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 3, May 2025.
Abstract Food waste causes significant environmental and economic challenges worldwide, prompting many nations to prioritize its reduction and recycling. As a nutrient‐rich material containing vitamins, proteins, and carbohydrates, it serves as a promising substrate for the cultivation of single‐cell microorganisms like yeast.

Cryopreservation of sugarcane embryogenic callus using a simplified freezing process [PDF]

CRYO-LETTERS, Volume: 19, Issue: 3, Pages: 171-176, Published: MAY-JUN 1998, Document Type:Article Published by Cryo-Letters, 7, Wootton Way, Cambridge CB3 9LX, U.K, 2020
A simplified freezing process was developed and successfully applied to embryogenic calluses of three sugarcane commercial hybrids (Saccharum sp. cv. CP 5243, C 91-301 and C 1051-73). To obtain optimal survival, the calluses were pretreated with a cryoprotective solution containing 10% DMSO and 0.3 to 0.75M sucrose.

Optimum storage conditions for osteochondral allograft plugs: An ex vivo comparative study of 12 storage protocols

Journal of Experimental Orthopaedics, Volume 12, Issue 2, April 2025.
Abstract Objective Physiological storage temperature and chondrogenic supplements can enhance tissue viability, potentially overcoming the limitations associated with osteochondral allograft transplantation. This study aimed to evaluate the quality of macroscopically healthy cartilage across 12 different storage protocols to find optimum storage ...

Investigating the Viability of Fat Cells Over 1, 3, and 6 Months After Freezing at −18°C

Journal of Cosmetic Dermatology, Volume 24, Issue 4, April 2025.
ABSTRACT Background Lipofilling is a natural, low‐risk, and long‐lasting method for filling, reconstructing, and improving soft tissues such as the face, with minimal discomfort for patients. Many plastic surgeons prefer autologous fat grafting in aesthetic surgery due to its availability, cost‐effectiveness, biocompatibility, and absence of allergic ...
