Can you get me the following papers? They're hosted on Springer. Also, you can't post the Springer download link. You have to upload them to a site like
DepositFiles (registration not reqauired; one-click upload). You can put all the papers in an archive to contain them all in one upload (e.g. .zip, .7z., .rar) or you can just upload them separately.
