I had been pleading, unsuccessfully, for Google to fix this issue, as well as many other scientists who use ArXiv daily. The latest post in the thread by Zhiyu Zhang brought up the fact that if you use the German mirror de.arxiv.org, the PDF files are properly tagged again.

This led me to make a change to Vox Charta’s ArXiv links, which now automatically point to de.arxiv.org if it detects the user is using Chrome. Also, I found that through ADS’ preferences that you can change your ArXiv mirror preference to the German mirror, ensuring that all ArXiv links point to this mirror. These changes completely solve the problem for me.

Update: I later learned that the APS mirror also handles PDFs correctly. This is probably a better option for those residing in the United States.

All of the new videos were uploaded to YouTube, which is widely compatible across all platforms and should hopefully play on most semi-modern computers. If you are having issues with playing the YouTube videos, you can downgrade the video quality to 480p or lower to achieve a better frame-rate. The movies posted previously from my other projects still require Quicktime, but I plan to export most of those to YouTube in the coming few days.

If you are interested in seeing what the collisions look like, I have just posted some movies from the simulations we performed in FLASH to the WD collisions project page. Check them out!
