## Summary
I think your proposed layout is excellent. It provides a clear and concise structure for presenting the research vision, background, proposed approach, challenges, and broader impact.

Here are some minor suggestions to further improve your layout:

1. **Introduction**: Consider adding a brief paragraph that highlights the significance of the research and its potential to address pressing cybersecurity concerns in industrial control systems.
2. **Background and Related Work**: Break up the bullet points into smaller sections or use subheadings to make it easier to follow. For example:
	* PLCs and Industrial Control Systems: Characteristics, Challenges, and Current State
	* Hardware-in-the-Loop Simulation: Overview, Current Players, and ARCADE Integration
3. **Proposed Approach**: Emphasize the innovative aspects of your approach by using bold headings or highlighting key takeaways. For example:
	* **ARCADE Setup at Pitt**: Successful integration with KOS and Beagleboards
	* **Why Our Approach is the Way to Go**: Unique blend of security, control engineering, and education
4. **Challenges and Limitations**: Use a clear and concise format to present the challenges and limitations. Consider using bullet points or numbered lists to make it easier to read.
5. **Broader Impact**: Use bold headings or highlight key phrases to emphasize the broader impact of your research. For example:
	* **Cybersecurity Elimination**: Potential for eliminating cybersecurity threats by integrating secure-by-design systems
	* **Control of Critical Infrastructure**: Demonstration of control capabilities with seL4-based systems
6. **Conclusion**: Summarize the main points and reiterate the significance of the research.
7. **References**: Use a consistent format throughout, and consider adding a brief note on how to access or retrieve the references.
