JOR SPINE, Volume 5, Issue 4, December 2022., 2022 Abstract Intervertebral disc degeneration is a common cause of low back pain, the leading cause of disability worldwide. Appropriate preclinical models for intervertebral disc research are essential to achieving a better understanding of underlying pathophysiology and for the development, evaluation, and translation of more effective treatments.

An agent framework for dynamic agent retraining: Agent academy [PDF]
In B. Stanford-Smith, E. Chiozza, and M. Edin, editors, Challenges
and Achievements in e-business and e-work, pages 757-764, Prague, Czech
Republic, October 2002. IOS Press, 2004 Agent Academy (AA) aims to develop a multi-agent society that can train new agents for specific or general tasks, while constantly retraining existing agents in a recursive mode. The system is based on collecting information both from the environment and the behaviors of the acting agents and their related successes/failures to generate a body of data,

Constructive agents nullify the ability of destructive agents to foster cooperation in public goods games [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science 34.10
(2024)Existing studies have revealed a paradoxical phenomenon in public goods games, wherein destructive agents, harming both cooperators and defectors, can unexpectedly bolster cooperation. Building upon this intriguing premise, our paper introduces a novel concept: constructive agents, which confer additional benefits to both cooperators and defectors.

An informational study of the evolution of codes and of emerging concepts in populations of agents [PDF]
arXiv, 2015 We consider the problem of the evolution of a code within a structured population of agents. The agents try to maximise their information about their environment by acquiring information from the outputs of other agents in the population. A naive use of information-theoretic methods would assume that every agent knows how to "interpret" the information

Agent TCP/IP: An Agent-to-Agent Transaction System [PDF]
arXivAutonomous agents represent an inevitable evolution of the internet. Current agent frameworks do not embed a standard protocol for agent-to-agent interaction, leaving existing agents isolated from their peers. As intellectual property is the native asset ingested by and produced by agents, a true agent economy requires equipping agents with a universal
