Access to cancer medications in LMICs is a major problem, especially in recent years, as th...

This letter clarifies the issue of compulsory reduction in linear derivation systems, and will be a helpful warning to new researchers in this area. Well known linear derivation systems include the ME procedure [3], SL-resolution [2], OL deduction [1], and the GC procedure [6]. Each of these systems incorporates a reduction operation to implement ancestor resolution and, in the GC procedure, a ...
