Here's the abstract:

Scheme's exception system is extended so that exception handlers
gain access to the delimited continuation representing the rest of
the computation of the call of the thunk guarded by the
handler. Algebraic effect handlers can be directly expressed in this
extended exception system. The system directly implements the
shift0/reset0 delimited control operators. It is well known that
other delimited control operators like prompt0/control0 or
reset/shift are expressible in shift0/reset0 (and vice versa).
