As regards the Ruki law *s > s^ in Balto-Slavic and Indo-Iranian when s
is preceded by any of r u k i,

Do we have cases like r u k i + T/D + s ?
Does the phonotactical "affricate" ts become s^ ?
or does it remain -s- ?
In other words, is there a different development when some intermediary
dental stop was there ?
